Atari Jaguar

The Atari Jaguar is a home video game console developed by Atari Corporation and released in North America in November 1993. Part of the fifth generation of video game consoles, it competed with the 16-bit Sega Genesis, the Super NES and the 32-bit 3DO Interactive Multiplayer that launched the same year. Powered by two custom 32-bit processors–Tom and Jerry–in addition to a Motorola 68000, Atari marketed it as the world's first 64-bit game system, emphasizing its 64-bit bus used by the blitter. The Jaguar launched with Cybermorph as the pack-in game, which received divisive reviews. The system's library ultimately comprised only 50 licensed games.

Development of the Atari Jaguar started in the early 1990s by Flare Technology, which focused on the system after cancellation of the Atari Panther console. The Jaguar was an important system for Atari after the company shifted its focus from computers - having ceased development of its Atari ST - back to consoles. However, the multi-chip architecture, hardware bugs, and poor tools made writing games for the Jaguar difficult. Underwhelming sales further eroded the console's third-party support.

Atari attempted to extend the lifespan of the system with the Atari Jaguar CD add-on, with an additional 13 games, and emphasizing the Jaguar's price of over US$100 less than its competitors. With the release of the Sega Saturn and PlayStation in 1995, sales of the Jaguar continued to fall. It sold no more than 150,000 units before it was discontinued in 1996. The commercial failure of the Jaguar prompted Atari to leave the console market.

After Hasbro Interactive acquired all Atari Corporation properties, the patents of the Jaguar were released into the public domain, with the console declared an open platform. Since its discontinuation, hobbyists have produced games for the system.

Development
Atari Corporation's previous home video game console, the Atari 7800, was released in 1986. While it sold 3.77 million units in the U.S. in the period to 1990, it was considered an 'also-ran' and far behind rival Nintendo. Around 1989 work began on a new console leveraging technology from their Atari ST computers. Originally named the Super XE - following the Atari XE Game System - it eventually became the Atari Panther using either 16 or 32-bit architecture. A more advanced system codenamed Jaguar also began work.

Both the Jaguar and Panther were developed by the members of Flare Technology, a company formed by Martin Brennan and John Mathieson. The team had claimed that they could not only make a console superior to the Genesis or the Super NES, but they could also be cost-effective. Impressed by their work on the Konix Multisystem, Atari persuaded them to close Flare and form a new company called Flare II, with Atari providing the funding.

Work on the Jaguar design progressed faster than expected, so Atari canceled the Panther project in 1991 to focus on the more promising Jaguar, and rumors were already circulating of a 1992 launch and its 32-bit or even 64-bit architecture. By this time the Atari ST had long been surpassed in popularity by the Amiga, while both Atari and Commodore became victims of 'Wintel', which would become the dominant computer platform. Support for Atari's legacy 8-bit products were dropped to fully focus on developing the Jaguar console, while their line of ST computers were dropped during the Jaguar's release in 1993.

The Atari Jaguar was unveiled in at the Summer Consumer Electronics Show in June 1993, calling it a "multi-media entertainment system".

Launch
The Jaguar was launched on November 23, 1993, at a price of $249.99, under a $500 million manufacturing deal with IBM. The system was initially available only in the test markets of New York City and San Francisco, with the slogan "Get bit by Jaguar", claiming superiority over competing 16-bit and 32-bit systems. During this test launch Atari sold all units hoping it would rally support for the system. A nationwide release followed six months later, in early 1994. The Jaguar struggled to attain a substantial user base. Atari reported that it had shipped 17,000 units as part of the system's initial test market in 1993. By the end of 1994, it reported that it had sold approximately 100,000 units.

Computer Gaming World wrote in January 1994 that the Jaguar was "a great machine in search of a developer/customer base", as Atari had to "overcome the stigma of its name (lack of marketing and customer support, as well as poor developer relations in the past)". Atari had "ventured late into third-party software support" for the Jaguar while competing console 3DO's "18 month public relations blitz" would result in "an avalanche of software support", the magazine reported. The small size and poor quality of the Jaguar's game library became the most commonly cited reason for the Jaguar's tepid adoption, as early releases like Trevor McFur in the Crescent Galaxy, Raiden, and Evolution: Dino Dudes also received poor reviews, the latter two for failing to take full advantage of the Jaguar's hardware. Jaguar did eventually earn praise with games such as Tempest 2000, Doom, and Wolfenstein 3D. The most successful title during the Jaguar's first year was Alien vs. Predator. However, these occasional successes were seen as insufficient while the Jaguar's competitors were receiving a continual stream of critically acclaimed software; GamePro concluded their rave review of Alien vs. Predator by remarking "If Atari can turn out a dozen more games like AvP, Jaguar owners could truly rest easy and enjoy their purchase." Next Generation commented that "thus far, Atari has spectacularly failed to deliver on the software side, leaving many to question the actual quality and capability of the hardware. With only one or two exceptions – Tempest 2000 is cited most frequently – there have just been no truly great games for the Jaguar up to now." They further noted that while Atari is well known by older gamers, the company had much less overall brand recognition than Sega, Sony, Nintendo, or even The 3DO Company. However, they argued that with its low price point, the Jaguar might still compete if Atari could improve the software situation.

Bit count controversy
Atari tried to downplay competing consoles by proclaiming the Jaguar was the only "64-bit" system; in its marketing in the American market the company used the tagline do the math!, in reference to the 64 number. This claim is questioned by some, because the Motorola 68000 CPU and the Tom and Jerry coprocessors execute 32-bit instruction sets. Atari's reasoning that the 32-bit Tom and Jerry chips work in tandem to add up to a 64-bit system was ridiculed in a mini-editorial by Electronic Gaming Monthly, which commented that "If Sega did the math for the Sega Saturn the way Atari did the math for their 64-bit Jaguar system, the Sega Saturn would be a 112-bit monster of a machine." Next Generation, while giving a mostly negative review of the Jaguar, maintained that it is a true 64-bit system, since the data path from the DRAM to the CPU and Tom and Jerry chips is 64 bits wide.

Arrival of Saturn and PlayStation
In early 1995, Atari announced that they had dropped the price of the Jaguar to $149.99, in order to be more competitive. Atari ran infomercials with enthusiastic salesmen touting the game system. These aired for most of 1995, but did not sell the remaining stock of Jaguar systems.

In a 1995 interview with Next Generation, then-CEO Sam Tramiel declared that the Jaguar was as powerful, if not more powerful, than the newly launched Sega Saturn, and slightly weaker than the upcoming PlayStation. Next Generation received a deluge of letters in response to Tramiel's comments, particularly his threat to bring Sony to court for price dumping if the PlayStation entered the U.S. market at a retail price below $300. Many readers found this threat hollow and hypocritical, since Tramiel noted in the same interview that Atari was selling the Jaguar at a loss. The editor responded that price dumping does not have to do with a product being priced below cost, but its being priced much lower in one country than another—which, as Tramiel said, is illegal. Tramiel and Next Generation agreed that the PlayStation's Japanese price converts to approximately $500. His remark, that the small number of third party Jaguar games was good for Atari's profitability, angered Jaguar owners who were already frustrated at how few games were coming out for the system.

In Atari's 1995 annual report, it noted: "Jaguar sales were substantially below Atari's expectations, and Atari's business and financial results were materially adversely affected in 1995 as Atari continued to invest heavily in Jaguar game development, entered into arrangements to publish certain licensed titles and reduced the retail price for its Jaguar console unit. Atari attributes the poor performance of Jaguar to a number of factors including (i) extensive delays in development of software for the Jaguar which resulted in reduced orders due to consumer concern as to when titles for the platform would be released and how many titles would ultimately be available, and (ii) the introduction of competing products by Sega and Sony in May 1995 and September 1995, respectively." In addition, Atari had severely limited financial resources, and so could not create the level of marketing which has historically backed successful gaming consoles.

Decline
By November 1995, mass layoffs and insider statements were fueling journalistic speculation that Atari had ceased both development and manufacturing for the Jaguar and was simply trying to sell off existing stock before exiting the video game industry. Although Atari continued to deny these theories going into 1996, core Jaguar developers such as High Voltage Software and Beyond Games stated that they were no longer receiving communications from Atari regarding future Jaguar projects.

In its 10-K405 SEC Filing, filed April 12, 1996, Atari informed stockholders that its revenues had declined by more than half, from $38.7 million in 1994 to $14.6 million in 1995, then gave them the news on the truly dire nature of the Jaguar:

"From the introduction of Jaguar in late 1993 through the end of 1995, Atari sold approximately 125,000 units of Jaguar. As of December 31, 1995, Atari had approximately 100,000 units of Jaguar in inventory."

The filing confirmed that Atari had abandoned the Jaguar in November 1995 and in the subsequent months were concerned chiefly with liquidating its inventory of Jaguar products. On April 8, 1996, Atari Corporation agreed to merge with JTS, Inc. in a reverse takeover, thus forming JTS Corporation. The merger was finalized on July 30.

After the merger, the bulk of Jaguar inventory remained unsold and would be finally moved out to Tiger Software, a private liquidator, on December 23, 1996. On March 13, 1998, JTS sold the Atari name and all of the Atari properties to Hasbro Interactive.

Technical specifications
From the Jaguar Software Reference manual, page 1:

"Jaguar is a custom chip set primarily intended to be the heart of a very high-performance games/leisure computer. It may also be used as a graphics accelerator in more complex systems, and applied to workstation and business uses. As well as a general purpose CPU, Jaguar contains four processing units. These are the Object Processor, Graphics Processor, Blitter, and Digital Sound Processor. Jaguar provides these blocks with a 64-bit data path to external memory devices, and is capable of a very high data transfer rate into external dynamic RAM."

Design specs for the console allude to the GPU or DSP being capable of acting as a CPU, leaving the Motorola 68000 to read controller inputs. Atari's Leonard Tramiel also specifically suggested that the 68000 not be used by developers. In practice, however, many developers use the Motorola 68000 to drive gameplay logic due to the greater developer familiarity of the 68000 and the adequacy of the 68000 for certain types of games. Most critically, a flaw in the memory controller means that certain obscure conventions must be followed for the RISC chips to be able to execute code from RAM.

The system was notoriously difficult to program for, not only because of its two-processor design but development tools were released in an unfinished state and the hardware had crippling bugs.

COJAG arcade games
Atari Games licensed the Atari Jaguar's chipset for use in its arcade games. The system, named COJAG (for "Coin-Op Jaguar"), replaced the 68000 with a 68020 or MIPS R3000-based CPU (depending on the board version), added more RAM, a full 64-bit wide ROM bus (Jaguar ROM bus being 32-bit), and optionally a hard drive (some games such as Freeze are ROM only). It runs the lightgun games Area 51 and Maximum Force, which were released by Atari as dedicated cabinets or as the Area 51 and Maximum Force combo machine. Other games were developed but never released: 3 On 3 Basketball, Fishin' Frenzy, Freeze, and Vicious Circle.

Peripherals
Prior to the launch of the console in November 1993, Atari had announced a variety of peripherals to be released over the console's lifespan. This included a CD-ROM-based console, a dial-up Internet link with support for online gaming, a virtual reality headset, and an MPEG-2 video card. However, due to the poor sales and eventual commercial failure of the Jaguar, most of the peripherals in development were canceled. The only peripherals and add-ons released by Atari for the Jaguar are a redesigned controller, an adapter for four players, a CD console add-on, and a link cable for local area network (LAN) gaming.

The redesigned second controller, the ProController by Atari, added three more face buttons and two triggers. It was created in response to the criticism of the original controller, said to lack enough buttons for fighting games in particular. Sold independently, however, it was never bundled with the system. The Team Tap multitap adds 4-controller support, compatible only with the optionally bundled White Men Can't Jump and NBA Jam Tournament Edition. Eight player gameplay with two Team Taps is possible but unsupported by those games. For LAN multiplayer support, the Jaglink Interface links two Jaguar consoles through a modular extension and a UTP phone cable. It is compatible with three games: AirCars, BattleSphere, and Doom.

In 1994 at the CES, Atari announced that it had partnered with Phylon, Inc. to create the Jaguar Voice/Data Communicator. The unit was delayed and an estimated 100 units were produced, but eventually in 1995 was canceled. The Jaguar Voice Modem or JVM utilizes a 19.9 kbit/s dial up modem to answer incoming phone calls and store up to 18 phone numbers. Players directly dial each other for online play, only compatible with Ultra Vortek which initializes the modem by entering 911 on the key pad at startup.

Jaguar CD
The Jaguar CD is a CD-ROM peripheral for games. It was released in September 1995, two years after the Jaguar's launch. Thirteen CD games were released during its manufacturing lifetime, with more being made later by homebrew developers. Each Jaguar CD unit has a Virtual Light Machine, which displays light patterns corresponding to music, if the user inserts an audio CD into the console. It was developed by Jeff Minter, after experimenting with graphics during the development of Tempest 2000. The program was deemed a spiritual successor to the Atari Video Music, a visualizer released in 1976.

The Memory Track is a cartridge accessory for the Jaguar CD, providing Jaguar CD games with 128 K EEPROM for persistent storage of data such as preferences and saved games. The Atari Jaguar Duo (codenamed Jaguar III) was a proposal to integrate the Jaguar CD to make a new console, a concept similar to the TurboDuo and Genesis CDX. A prototype, described by journalists as resembling a bathroom scale, was unveiled at the 1995 Winter Consumer Electronics Show, but the console was canceled before production.

Jaguar VR
A virtual reality headset compatible with the console, tentatively titled the Jaguar VR, was unveiled by Atari at the 1995 Winter Consumer Electronics Show. The development of the peripheral was a response to Nintendo's virtual reality console, the Virtual Boy, which had been announced the previous year. The headset was developed in cooperation with Virtuality, which had previously created many virtual reality arcade systems, and was already developing a similar headset for practical purposes, named Project Elysium, for IBM. The peripheral was targeted for a commercial release before Christmas 1995. However, the deal with Virtuality was abandoned in October 1995. After Atari's merger with JTS in 1996, all prototypes of the headset were allegedly destroyed. However, two working units, one low-resolution prototype with red and grey-colored graphics and one high-resolution prototype with blue and grey-colored graphics, have since been recovered, and are regularly showcased at retrogaming-themed conventions and festivals. Only one game was developed for the Jaguar VR prototype: a 3D-rendered version of the 1980 arcade game Missile Command, titled Missile Command 3D, and a demo of Virtuality's Zone Hunter was created.

Unlicensed peripherals
An unofficial expansion peripheral for the Atari Jaguar dubbed the "Catbox" was released by the Rockford, Illinois company ICD. It was originally slated to be released early in the Jaguar's life, in the second quarter of 1994, but was not actually released until mid-1995. The ICD CatBox plugs directly into the AV/DSP connectors located in the rear of the Jaguar console and provides three main functions. These are audio, video, and communications. It features six output formats, three for audio (line level stereo, RGB monitor, headphone jack with volume control) and three for video (composite, S-Video, and RGB analog component video) making the Jaguar compatible with multiple high quality monitor systems and multiple monitors at the same time. It is capable of communications methods known as CatNet and RS-232 as well as DSP pass through, allowing the user to connect two or more Jaguars together for multiplayer games either directly or with modems. The ICD CatBox features a polished stainless steel casing and red LEDs in the jaguar's eyes on the logo that indicate communications activity. An IBM AT-type null modem cable may be used to connect two Jaguars together. The CatBox is also compatible with Atari's Jaglink Interface peripheral.

An adaptor for the Jaguar that allows for WebTV access was revealed in 1998; one prototype is known to exist.

Reception
Reviewing the Jaguar just a few weeks prior to its launch, GamePro gave it a "thumbs sideways". They praised the power of the hardware but criticized the controller, and were dubious of how the software lineup would turn out, commenting that Atari's failure to secure support from key third party publishers such as Capcom was a bad sign. They concluded that "Like the 3DO, the Jaguar is a risky investment – just not quite as expensive."

The Jaguar won GameFan's "Best New System" award for 1993.

The small size and poor quality of the Jaguar's game library became the most commonly cited reason for its failure in the marketplace. The pack-in game Cybermorph was one of the first polygon-based games for consoles, but was criticized for design flaws and a weak color palette, and compared unfavorably with the SNES's Star Fox. Other early releases like Trevor McFur in the Crescent Galaxy, Raiden, and Evolution: Dino Dudes also received poor reviews, the latter two for failing to take full advantage of the Jaguar's hardware. Jaguar did eventually earn praise with games such as Tempest 2000, Doom, and Wolfenstein 3D. The most successful title during the Jaguar's first year was Alien vs. Predator. However, these occasional successes were seen as insufficient while the Jaguar's competitors were receiving a continual stream of critically acclaimed software; GamePro concluded their rave review of Alien vs. Predator by remarking "If Atari can turn out a dozen more games like AvP, Jaguar owners could truly rest easy and enjoy their purchase." In late 1995 reviews of the Jaguar, Game Players remarked, "The Jaguar suffers from several problems, most importantly the lack of good software." and Next Generation likewise commented that "thus far, Atari has spectacularly failed to deliver on the software side, leaving many to question the actual quality and capability of the hardware. With only one or two exceptions – Tempest 2000 is cited most frequently – there have just been no truly great games for the Jaguar up to now." They further noted that while Atari is well known by older gamers, the company had much less overall brand recognition than Sega, Sony, Nintendo, or even The 3DO Company. However, they argued that with its low price point, the Jaguar might still compete if Atari could improve the software situation. They gave the system two out of five stars. Game Players also stated the despite being 64-bit, the Jaguar is much less powerful than the 3DO, Saturn, and PlayStation, even when supplemented with the Jaguar CD. With such a small library of games to challenge the incumbent 16-bit game consoles, Jaguar's appeal never grew beyond a small gaming audience. Digital Spy commented: "Like many failed hardware ventures, it still maintains something of a cult following but can only be considered a misstep for Atari."

In 2006 IGN editor Craig Harris rated the original Jaguar controller as the worst game controller ever, criticizing the unwarranted recycling of the 1980s "phone keypad" format and the small number of action buttons, which he found particularly unwise given that Atari was actively trying to court fighting game fans to the system. Ed Semrad of Electronic Gaming Monthly commented that many Jaguar games gratuitously used all of the controller's phone keypad buttons, making the controls much more difficult than they needed to be. GamePro's The Watch Dog remarked, "The controller usually doesn't use the keypad, and for games that use the keypad extensively (Alien vs. Predator, Doom), a keypad overlay is used to minimize confusion. But yes, it is a lot of buttons for nuttin'." Atari added more action buttons for its Pro Controller, to improve performance in fighting games in particular.

Legacy
Telegames continued to publish games for the Jaguar after it was discontinued, and for a time was the only company to do so. On May 14, 1999, Hasbro Interactive announced that it had released all patents to the Jaguar, declaring it an open platform; this opened the doors for extensive homebrew development. Following the announcement, Songbird Productions joined Telegames in releasing unfinished Jaguar games alongside new games to satisfy the cult following. Hasbro Interactive, along with all the Atari properties, was sold to Infogrames on January 29, 2001.

In the United Kingdom in 2001, Telegames and retailer Game made a deal to bring the Jaguar to Game's retail outlets. It was initially sold for £29.99 new and software ranged between £9.99 for more common games such as Doom and Ruiner Pinball and £39.99 for rarer releases such as Defender 2000 and Checkered Flag. The machine had a presence in the stores until 2007, when remaining consoles were sold off for £9.99 and games were sold for as low as 97p.

In 2022, the compilation Atari 50 released with a collection of Jaguar titles, being one of the first instances of Jaguar software being officially rereleased by Atari. Due to the unique design of the original Jaguar controller, the games feature reworked control layouts to allow them to work with modern hardware.

Molds
In 1997, Imagin Systems, a manufacturer of dental imaging equipment, purchased the Jaguar cartridge and console molds, including the molds for the CD add-on, from JTS. The console molds could, with minor modification, fit their HotRod camera, and the cartridge molds were reused to create an optional memory expansion card. In a retrospective, Imagin founder Steve Mortenson praised the design, but admitted that their device came at the time of the dental industry's transition to USB, and apart from a few prototypes, the molds went unused.

In December 2014, the molds were purchased from Imagin Systems by Mike Kennedy, owner of the Kickstarter funded Retro Videogame Magazine, to propose a new crowdfunded video game console, the Retro VGS, later rebranded the Coleco Chameleon after entering a licensing agreement with Coleco. The purchase of the molds was far cheaper than designing and manufacturing entirely new molds, and Kennedy described their acquisition as "the entire reason [the Retro VGS] is possible". However, the project was terminated in March 2016 following criticism of Kennedy and doubts regarding demand for the proposed console. Two "prototypes" were discovered to be fakes and Coleco withdrew from the project. After the project's termination, the molds were sold to Albert Yarusso, the founder of the AtariAge website.

Atari Lynx

The Atari Lynx is a 16-bit fourth-generation hand-held game console released by Atari Corporation in September 1989 in North America and 1990 in Europe and Japan. It was the first handheld game console with a color liquid-crystal display. Powered by a 4 MHz 65C02 8-bit CPU and a custom 16-bit blitter, the Lynx was more advanced than Nintendo's monochrome Game Boy, released two months earlier. It also competed with Sega's Game Gear and NEC's TurboExpress, released the following year.

The system was developed at Epyx by two former designers of the Amiga personal computers. The project was called the Handy Game or simply Handy. In 1991, Atari replaced the Lynx with a smaller model internally referred to as the Lynx II. Atari published a total of 73 games for the Lynx before it was discontinued in 1995.

History
The Lynx system was originally developed by Epyx as the Handy Game. In 1986, two former Amiga designers, RJ Mical and Dave Needle, had been asked by a former manager at Amiga, Dave Morse, to design a portable gaming system. Morse now worked at Epyx, a game software company with a recent string of hit games. Morse's son had asked him if he could make a portable gaming system, prompting a meeting with Mical and Needle to discuss the idea. Morse convinced Mical and Needle and they were hired by Epyx to be a part of the design team. Planning and design of the console began in 1986 and was completed in 1987. Epyx first showed the Handy system at the Winter Consumer Electronics Show (CES) in January 1989. Facing financial difficulties, Epyx sought partners. Nintendo, Sega, and other companies declined, but Atari and Epyx eventually agreed that Atari would handle production and marketing, and Epyx would handle software development. Epyx declared bankruptcy by the end of the year, so Atari essentially owned the entire project. Both Atari and others had to purchase Amigas from Atari arch-rival Commodore in order to develop Lynx software.

The Handy was designed to run games from the cartridge format, and the game data must be copied from ROM to RAM before it can be used. Thus, less RAM is then available and each game's initial loading is slow. There are trace remnants of a cassette tape interface physically capable of being programmed to read a tape. Lynx developers have noted that "there is still reference of the tape and some hardware addresses" and an updated vintage Epyx manual describes the bare existence of what could be utilized for tape support. A 2009 retrospective interview with Mical clarifies that there is no truth to some early reports claiming that games were loaded from tape, and elaborates, "We did think about hard disk a little."

The networking system was originally developed to run over infrared links and codenamed RedEye. This was changed to a cable-based networking system before the final release as the infrared beam was too easily interrupted when players walked through the beam, according to Peter Engelbrite. Engelbrite developed the first recordable eight-player co-op game, and the only eight-player game for the Lynx, Todd's Adventures in Slime World.

Atari changed the internal speaker and removed the thumb stick on the control pad. At Summer 1989 CES, Atari's press demonstration included the "Portable Color Entertainment System", which was changed to "Lynx" when distributed to resellers, initially retailing in the US at US$179.95 1989.

Its launch was successful. Atari reported that it had sold 90% of the 50,000 units shipped in the launch month in the U.S. with a limited launch in New York. US sales in 1990 were approximately 500,000 units according to the Associated Press. In late 1991, it was reported that Atari sales estimates were about 800,000, which Atari claimed was within its expected projections. Lifetime sales by 1995 amount to fewer than 7 million units when combined with the Game Gear. In comparison, 16 million Game Boy units were sold by 1995 because of its superior durability, pricing, battery life, and game library, notably the pack-in hit Tetris.

As with the console units, the game cartridge design evolved over the first year of the console's release. The first generation of cartridges are flat, and designed to be stackable for ease of storage. However, this design proved to be very difficult to remove from the console and was replaced by a second design. This style, called "tabbed" or "ridged", adds two small tabs on the underside to aid in removal. The original flat style cartridges can be stacked on top of the newer cartridges, but the newer cartridges can not be easily stacked on each other, nor were they stored easily. Thus a third style, the "curved lip" style was produced, and all official and third-party cartridges during the console's lifespan were released (or re-released) using this style.

In May 1991, Sega launched its Game Gear portable gaming handheld with a color screen. In comparison to the Lynx it had shorter battery life (3–4 hours as opposed to 4-5 for the Lynx), but it is slightly smaller, has significantly more games, and cost $30 less than the Lynx at launch.

Retailers such as Game and Toys "R" Us continued to sell the Lynx well into the mid-1990s on the back of the Atari Jaguar launch, helped by magazines such as Ultimate Future Games which continued to cover the Lynx alongside the new generation of 32-bit and 64-bit consoles.

Lynx II

In July 1991, Atari introduced a new version of the Lynx, internally called the "Lynx II", with a new marketing campaign, new packaging, slightly improved hardware, better battery life, and a sleeker look. It has rubber hand grips and a clearer backlit color screen with a power save option (which turns off the backlighting). The monaural headphone jack of the original Lynx was replaced with one wired for stereo. The Lynx II was available without any accessories, dropping the price to US$99 1990.

Decline
In 1993, Atari started shifting its focus away from the Lynx in order to prepare for the launch of the Jaguar; a few games were released during that time, including Battlezone 2000. Support for the Lynx was formally discontinued in 1995.

After the respective launches of the Sega Saturn and Sony PlayStation caused the commercial failure of the Jaguar, Atari ceased all game development and hardware manufacturing by early 1996 and would later merge with JTS, Inc. on July 30 of that year.

Features
The Atari Lynx has a backlit color LCD display, switchable right- and left-handed (upside down) configuration, and the ability to network with other units via Comlynx cable. The maximum stable connection allowed is eight players. Each Lynx needs a copy of the game, and one cable can connect two machines. The cables can be connected into a chain.

The Lynx was cited as the "first gaming console with hardware support for zooming and distortion of sprites". With a 4096 color palette and integrated maths and graphics co-processors (including a sprite engine unit), its color graphics display was said to be the key defining feature in the system's competition against Nintendo's monochromatic Game Boy. The fast pseudo-3D graphics features were made possible on a minimal hardware system by co-designer Dave Needle having "invented the technique for planar expansion/shrinking capability" and using stretched triangles instead of full polygons.

Reception
Lynx was reviewed in 1990 in Dragon, which gave it 5 out of 5 stars. The review states that the Lynx "throws the Game Boy into the prehistoric age", and praises the built-in object scaling capabilities, the multiplayer feature of the ComLynx cable, and the strong set of launch games.

Legacy
Telegames released several games in the late 1990s, including a port of Raiden and a platformer called Fat Bobby in 1997, and an action sports game called Hyperdrome in 1999.

On March 13, 1998, nearly three years after the Lynx's discontinuation, JTS Corporation sold all of the Atari assets to Hasbro Interactive for $5 million. On May 14, 1999, Hasbro, which held on to those properties until selling Hasbro Interactive to Infogrames in 2001, released into the public domain all rights to the Jaguar, opening up the platform for anyone to publish software on without Hasbro's interference. Internet theories say that the Lynx's rights may have been released to the public at the same time as the Jaguar, but this is clearly disputed. Nevertheless, since discontinuation, the Lynx, like the Jaguar, has continued to receive support from a grassroots community which would go on to produce many successful homebrew games such as T-Tris (the first Lynx game with a save-game feature), Alpine Games, and Zaku.

In 2008, Atari was honored at the 59th Annual Technology & Engineering Emmy Awards for pioneering the development of handheld games with the Lynx.

In 2022, the compilation Atari 50 released with a handful of popular Lynx titles, marking the first time that classic Lynx software would be officially rereleased by Atari.

Ahimsa

 (अहिंसा, IAST:, lit. 'nonviolence' ) is the ancient Indian principle of nonviolence which applies to actions towards all living beings. It is a key virtue in Indian religions like Jainism, Buddhism, Hinduism, and Sikhism.

is one of the cardinal virtues of Jainism, where it is the first of the Pancha Mahavrata. It is also one of the central precepts of Hinduism and is the first of the five precepts of Buddhism. is inspired by the premise that all living beings have the spark of the divine spiritual energy; therefore, to hurt another being is to hurt oneself. is also related to the notion that all acts of violence have karmic consequences. While ancient scholars of Brahmanism had already investigated and refined the principles of, the concept reached an extraordinary development in the ethical philosophy of Jainism. Mahavira, the twenty-fourth and the last of Jainism, further strengthened the idea in. About, Thiruvalluvar emphasized and moral vegetarianism as virtues for an individual, which formed the core of his teachings in the Kural. Perhaps the most popular advocate of the principle of in modern times was Mahatma Gandhi.

's precept that humans should 'cause no injury' to another living being includes one's deeds, words, and thoughts. Classical Hindu texts like the Mahabharata and the Ramayana, as well as modern scholars, disagree about what the principle of dictates when one is faced with war and other situations that require self-defence. In this way, historical Indian literature has contributed to modern theories of just war and self-defence.

Etymology
The word —sometimes spelled —is derived from the Sanskrit root, meaning to strike;  is injury or harm, while  (prefixed with the alpha privative), its opposite, is non-harming or nonviolence.

Origins
Reverence for can be found in Jain, Hindu, and Buddhist canonical texts. Lord Parshvanatha (the 23rd of 24 Tirthankaras of Jainism) is said to have preached as one of the four vows. No other Indian religion has developed the non-violence doctrine and its implications on everyday life as much as has Jainism.

Ancient Vedic texts
as an ethical concept evolved in the Vedic texts. The oldest scriptures indirectly mention. Over time, the Hindu scripts revised ritual practices, and the concept of was increasingly refined and emphasized until  became the highest virtue by the late Vedic era (about ). For example, hymn 10.22.25 in the Rig Veda uses the words (truthfulness) and  in a prayer to deity Indra; later, the Yajur Veda dated to be between  and, states, "may all beings look at me with a friendly eye, may I do likewise, and may we look at each other with the eyes of a friend".

The term appears in the text Taittiriya Shakha of the Yajurveda (TS 5.2.8.7), where it refers to non-injury to the sacrificer himself. It occurs several times in the Shatapatha Brahmana in the sense of "non-injury". The doctrine is a late Vedic era development in Brahmanical culture. The earliest reference to the idea of non-violence to animals, apparently in a moral sense, is in the Kapisthala Katha Samhita of the Yajurveda (KapS 31.11), which may have been written in about.

John Bowker states the word appears but is uncommon in the principal Upanishads. Kaneda gives examples of the word in these Upanishads. Other scholars suggest  as an ethical concept started evolving in the Vedas, becoming an increasingly central concept in Upanishads.

The Chāndogya Upaniṣad, dated to, one of the oldest Upanishads, has the earliest evidence for the Vedic era use of the word in the sense familiar in Hinduism (a code of conduct). It bars violence against "all creatures", and the practitioner of is said to escape from the cycle of rebirths (CU 8.15.1). Some scholars state that this mention may have been an influence of Jainism on Vedic Hinduism. Others scholar state that this relationship is speculative, and though Jainism is an ancient tradition the oldest traceable texts of Jainism tradition are from many centuries after the Vedic era ended.

Chāndogya Upaniṣad also names, along with (truthfulness),  (sincerity),  (charity), and  (penance/meditation), as one of five essential virtues (CU 3.17.4).

The Sandilya Upanishad lists ten forbearances:, , , , , , , , , and. According to Kaneda, the term is an important spiritual doctrine shared by Hinduism, Buddhism, and Jainism. It means 'non-injury' and 'non-killing'. It implies the total avoidance of harming any living creature by deeds, words, and thoughts.

The Epics
The Mahabharata, one of the epics of Hinduism, has multiple mentions of the phrase (अहिंसा परमॊ धर्मः), which literally means: non-violence is the highest moral virtue. For example, Anushasana Parva has the verse: अहिंसा परमॊ धर्मः तथाहिंसा परॊ दमः। अहिंसा परमं दानम् अहिंसा परमस तपः। अहिंसा परमॊ यज्ञः तथाहिस्मा परं बलम्। अहिंसा परमं मित्रम् अहिंसा परमं सुखम्। अहिंसा परमं सत्यम् अहिंसा परमं श्रुतम्॥ The above passage from Mahabharata emphasises the cardinal importance of in Hinduism, and literally means: is the highest, is the highest self-control, is the greatest gift, is the best practice, is the highest sacrifice, is the finest strength, is the greatest friend, is the greatest happiness, is the highest truth, and is the greatest teaching. Some other examples where the phrase are discussed include Adi Parva, Vana Parva, and Anushasana Parva. The Bhagavad Gita, among other things, discusses the doubts and questions about appropriate response when one faces systematic violence or war. These verses develop the concepts of lawful violence in self-defence and the theories of just war. However, there is no consensus on this interpretation. Gandhi, for example, considers this debate about non-violence and lawful violence as a mere metaphor for the internal war within each human being, when he or she faces moral questions.

Self-defence, criminal law, and war
The classical texts of Hinduism devote numerous chapters to discussing what people who practice the virtue of can and must do when faced with war, violent threat, or the need to sentence someone convicted of a crime. These discussions have led to theories of just war, ideas of reasonable self-defense, and views of proportionate punishment. Arthashastra discusses, among other things, what constitutes proportionate response and punishment.

The precepts of in Hinduism require that war must be avoided, with sincere and truthful dialogue. Force must be the last resort. If war becomes necessary, its cause must be just, its purpose virtuous, its objective to restrain the wicked, its aim peace, and its method lawful. War can only be started and stopped by a legitimate authority. Weapons must be proportionate to the opponent and the aim of war, not indiscriminate tools of destruction. All strategies and weapons used in the war must be to defeat the opponent, not to cause misery to the opponent; for example, the use of arrows is allowed, but the use of arrows smeared with painful poison is not allowed. Warriors must use judgment in the battlefield. Cruelty to the opponent during war is forbidden. Wounded, unarmed opponent warriors must not be attacked or killed; they must be brought to your realm and given medical treatment. Children, women, and civilians must not be injured. While the war is in progress, sincere dialogue for peace must continue.
 * War

Different interpretations of ancient Hindu texts have been offered in matters of self-defense. For example, Tähtinen suggests self-defense is appropriate, criminals are not protected by the rule of, and Hindu scriptures support violence against an armed attacker. is not meant to imply pacifism.
 * Self-defence

Alternative theories of self-defense, inspired by, build principles similar to ideas of just war. Aikido, pioneered in Japan, illustrates one such set of principles for self-defense. Morihei Ueshiba, the founder of Aikido, described his inspiration as Ahimsa. According to this interpretation of in self-defense, one must not assume that the world is free of aggression. One must presume that some people will, out of ignorance, error, or fear, attack others or intrude into their space, physically or verbally. The aim of self-defense, suggested Ueshiba, must be to neutralize the attacker's aggression and avoid conflict. The best defense is one with which the victim is protected and the attacker is respected and not injured if possible. Under and Aikido, there are no enemies, and appropriate self-defense focuses on neutralizing the immaturity, assumptions, and aggressive strivings of the attacker.

Tähtinen concludes that Hindus have no misgivings about the death penalty; their position is that evil-doers who deserve death should be killed and that a king, in particular, is obliged to punish criminals and should not hesitate to kill them, even if they happen to be his brothers and sons.
 * Criminal law

Other scholars conclude that Hindu scriptures suggest that sentences for any crime must be fair, proportional, and not cruel.

Non-human life
The Hindu precept of "cause no injury" applies to animals and all life forms. This precept is not found in the oldest verses of Vedas, but increasingly becomes one of the central ideas in post-Vedic period. In the oldest layer of the Vedas, such as the Rigveda, ritual sacrifices of animals and cooking of meat to feed guests are mentioned. This included goat, ox, horse, and others. However, the text is not uniform in its prescriptions. Some verses praise meat as food, while other verses in the Vedas recommend "abstention from meat", in particular, "beef". According to Marvin Harris, the Vedic literature is inconsistent, with some verses suggesting ritual slaughter and meat consumption, while others suggesting a taboo on meat-eating.

Hindu texts dated to initially mention meat as food, then evolve to suggest that only meat obtained through ritual sacrifice can be eaten, thereafter evolving to the stance that one should eat no meat because it hurts animals, with verses describing the noble life as one that lives on flowers, roots, and fruits alone. The late Vedic-era literature condemns all killings of men, cattle, birds, and horses, and prays to god Agni to punish those who kill.

Later texts of Hinduism declare one of the primary virtues, declare any killing or harming any life as against  (moral life). Finally, the discussion in Upanishads and Hindu Epics shifts to whether a human being can ever live his or her life without harming animal and plant life in some way, which and when plants or animal meat may be eaten, whether violence against animals causes human beings to become less compassionate, and if and how one may exert least harm to non-human life consistent with, given the constraints of life and human needs. The Mahabharata permits hunting by warriors, but opposes it in the case of hermits who must be strictly non-violent. Sushruta Samhita, a Hindu text written in, in Chapter XLVI suggests proper diet as a means of treating certain illnesses, and recommends various fishes and meats for different ailments and for pregnant women, and the Charaka Samhita describes meat as superior to all other kinds of food for convalescents.

Across the texts of Hinduism, there is a profusion of ideas about the virtue of when applied to non-human life, but without a universal consensus. Alsdorf claims the debate and disagreements between supporters of vegetarian lifestyle and meat eaters was significant. Even suggested exceptions – ritual slaughter and hunting – were challenged by advocates of. In the Mahabharata both sides present various arguments to substantiate their viewpoints. Moreover, a hunter defends his profession in a long discourse.

Many of the arguments proposed in favor of non-violence to animals refer to the bliss one feels, the rewards it entails before or after death, the danger and harm it prevents, as well as to the karmic consequences of violence.

The ancient Hindu texts discuss and non-animal life. They discourage wanton destruction of nature including of wild and cultivated plants. Hermits (sannyasins) were urged to live on a fruitarian diet so as to avoid the destruction of plants. Scholars claim the principles of ecological nonviolence are innate in the Hindu tradition, and its conceptual fountain has been as its cardinal virtue.

The classical literature of the Indian religions, such as Hinduism and Jainism, exists in many Indian languages. For example, the Tirukkural, written in three volumes, likely between, dedicates verses 251–260 and 321–333 of its first volume to the virtue of , emphasizing on moral vegetarianism and non-killing. However, the Tirukkural also glorifies soldiers and their valour during war, and states that it is king's duty to punish criminals and implement "death sentence for the wicked".

In 1960, H. Jay Dinshah founded the American Vegan Society (AVS), linking veganism to the concept of.

Modern times
In the 19th and 20th centuries, prominent figures of Indian spirituality such as Shrimad Rajchandra and Swami Vivekananda emphasised the importance of Ahimsa.

Mohandas Karamchand Gandhi successfully promoted the principle of to all spheres of life, in particular to politics. His non-violent resistance movement had an immense impact on India, impressed public opinion in Western countries, and influenced the leaders of various civil and political rights movements such as the American civil rights movement's Martin Luther King Jr. and James Bevel. In Gandhi's thought, precludes not only the act of inflicting a physical injury but also mental states like evil thoughts and hatred, and unkind behavior such as harsh words, dishonesty, and lying, all of which he saw as manifestations of violence incompatible with. Gandhi believed to be a creative energy force, encompassing all interactions leading one's self to find, "Divine Truth". Sri Aurobindo criticized the Gandhian concept of as unrealistic and not universally applicable; he adopted a pragmatic non-pacifist position, saying that the justification of violence depends on the specific circumstances of the given situation.

Gandhi took the religious principle of ahimsa, and turned it into a non-violent tool for mass action. He used it to fight not only colonial rule, but social evils such as racial discrimination and untouchability as well.

Gandhi stated his belief that " is in Hinduism, it is in Christianity as well as in Islam." He added, "Nonviolence is common to all religions, but it has found the highest expression and application in Hinduism (I do not regard Jainism or Buddhism as separate from Hinduism)." When questioned whether violence and nonviolence are taught in Quran, he stated, "I have heard from many Muslim friends that the Koran teaches the use of nonviolence. (... The) argument about nonviolence in the Holy Koran is an interpolation, not necessary for my thesis."

Studying 's history and philosophy influenced Albert Schweitzer's principle of "reverence for life." He commended Indian traditions for their ethics of, considering the prohibition against killing and harming "one of the greatest events in the spiritual history of humankind". However, he noted that "not-killing" and "not-harming" might be unfeasible in certain situations, like self-defense, or ethically complex, as in cases of prolonged famine.

Yoga
is imperative for practitioners of Patañjali's eight limb Raja yoga system. It is included in the first limb and is the first of five (self restraints) which, together with the second limb, make up the code of ethical conduct in Yoga philosophy. is also one of the ten in Hatha Yoga according to verse 1.1.17 of its classic manual Hatha Yoga Pradipika. The significance of as the first restraint in the first limb of Yoga, is that it defines the necessary foundation for progress through Yoga. It is a precursor to, implying that success in can be had only if the self is purified in thought, word, and deed through the self-restraint of.

Jainism
In Jainism, the understanding and implementation of is more radical, scrupulous, and comprehensive than in any other religion. Killing any living being is considered  (to injure) and abstaining from such an act is  (noninjury). The vow of is considered the foremost among the "five vows of Jainism". Other vows like truth are meant for safeguarding the vow of.

In the practice of, the requirements are less strict for the lay persons who have undertaken  (Smaller Vows) than for the Jain monastics who are bound by the Mahavrata "Great Vows".

The statement (or, "Non-injury/nonviolence/harmlessness is the supreme/ultimate/paramount/highest/absolute duty/virtue/attribute/religion") is often found inscribed on the walls of the Jain temples. As in Hinduism, the aim is to prevent the accumulation of harmful karma.

When Mahavira revived and reorganised the Jain faith in, was already an established, strictly observed rule. Rishabhanatha (Ādinātha), the first Jain Tirthankara, whom modern Western historians consider to be a historical figure, followed by Parshvanatha (Pārśvanātha) the twenty-third Tirthankara lived in about. He founded the community to which Mahavira's parents belonged. Ahimsa was already part of the "Fourfold Restraint" (Caujjama), the vows taken by Parshva's followers. In the times of Mahavira and in the following centuries, Jains were at odds with both Buddhists and followers of the Vedic religion or Hindus, whom they accused of negligence and inconsistency in the implementation of. According to the Jain tradition either lacto vegetarianism or veganism is prescribed.

The Jain concept of is characterised by several aspects. Killing of animals for food is absolutely ruled out. Jains also make considerable efforts not to injure plants in everyday life as far as possible. Though they admit that plants must be destroyed for the sake of food, they accept such violence only inasmuch as it is indispensable for human survival, and there are special instructions for preventing unnecessary violence against plants. Jain monks and nuns go out of their way so as not to hurt even small insects and other minuscule animals. Both the renouncers and the laypeople of Jain faith reject meat, fish, alcohol, and honey as these are believed to harm large or minuscule life forms.

Jain scholars have debated the potential injury to other life forms during one's occupation. Certain Jain texts (according to Padmannabh Jaini, a Jainism scholar) forbid people of its faith from husbandry, agriculture, and trade in animal-derived products. Some Jains abstain from farming because it inevitably entails unintentional killing or injuring of many small animals, such as worms and insects. These teachings, in part, have led the Jain community to focus on trade, merchant, clerical, and administrative occupations to minimize (occupational violence against all life forms). For the layperson, the teaching has been of with  – that is, reducing violence through proper intention and being careful in every action on a daily basis to minimize violence to all life forms.

The Jain texts, unlike most Hindu and Buddhist texts on just war, have been inconsistent. For its monastic community – and  – the historically accepted practice has been to "willingly sacrifice one's own life" to the attacker, to not retaliate, so that the mendicant may keep the First Great Vow of "total nonviolence". Jain literature of, for example, describes a king ready for war and being given lessons about non-violence by the Jain acharya (spiritual teacher). In and thereafter, in an era of violent raids, destruction of temples, the slaughter of agrarian communities and ascetics by Islamic armies, Jain scholars reconsidered the First Great Vow of mendicants and its parallel for the laypeople. The medieval texts of this era, such as by Jinadatta Suri, recommended both the mendicants and the laypeople to fight and kill if that would prevent greater and continued violence on humans and other life forms. Such exemptions to is a relatively rare teaching in Jain texts, states Dundas.

Mahatma Gandhi stated, "No religion in the World has explained the principle of so deeply and systematically as is discussed with its applicability in every human life in Jainism. As and when the benevolent principle of  or non-violence will be ascribed for practice by the people of the world to achieve their end of life in this world and beyond, Jainism is sure to have the uppermost status and Mahāvīra is sure to be respected as the greatest authority on ".

Buddhism

In Buddhist texts (or its Pāli cognate ) is part of the Five Precepts, the first of which has been to abstain from killing. This precept of is applicable to both the Buddhist layperson and the monk community.

The precept is not a commandment, and transgressions did not  for laypersons, but their power has been in the Buddhist belief in karmic consequences and their impact in afterlife during rebirth. Killing, in Buddhist belief, could lead to rebirth in the hellish realm, and for a longer time in more severe conditions if the murder victim was a monk. Saving animals from slaughter for meat is believed to be a way to acquire merit for better rebirth. These moral precepts have been voluntarily self-enforced in lay Buddhist culture through the associated belief in karma and rebirth. Buddhist texts not only recommend, but suggest avoiding trading goods that contribute to or are a result of violence:

"These five trades, O monks, should not be taken up by a lay follower: trading with weapons, trading in living beings, trading in meat, trading in intoxicants, trading in poison."

Unlike with lay Buddhists, transgressions by monks do invite sanctions. Full expulsion of a monk from follows instances of killing, just like any other serious offense against the monastic  code of conduct.

War
Violent ways of punishing criminals and prisoners of war were not explicitly condemned in Buddhism, but peaceful ways of conflict resolution and punishment with the least amount of injury were encouraged. The early texts condemn the mental states that lead to violent behavior.

Nonviolence is an theme within the Pāli Canon. While the early texts condemn killing in the strongest terms, and portray the ideal queen/king as a pacifist, such a queen/king is nonetheless flanked by an army. It seems that the Buddha's teaching on nonviolence was not interpreted or put into practice in an uncompromisingly pacifist or anti-military-service way by early Buddhists. The early texts assume war to be a fact of life, and well-skilled warriors are viewed as necessary for defensive warfare. In Pali texts, injunctions to abstain from violence and involvement with military affairs are directed at members of the ; later Mahayana texts, which often generalise monastic norms to laity, require this of lay people as well.

The early texts do not contain just-war ideology as such. Some argue that a in the Gamani Samyuttam rules out all military service. In this passage, a soldier asks the Buddha if it is true that, as he has been told, soldiers slain in battle are reborn in a heavenly realm. The Buddha reluctantly replies that if he is killed in battle while his mind is seized with the intention to kill, he will undergo an unpleasant rebirth. In the early texts, a person's mental state at the time of death is generally viewed as having a great impact on the next birth.

Some Buddhists point to other early texts as justifying defensive war. One example is the Kosala Samyutta, in which King Pasenadi, a righteous king favored by the Buddha, learns of an impending attack on his kingdom. He arms himself in defence, and leads his army into battle to protect his kingdom from attack. He lost this battle but won the war. King Pasenadi eventually defeated King Ajātasattu and captured him alive. He thought that, although this King of Magadha has transgressed against his kingdom, he had not transgressed against him personally, and Ajātasattu was still his nephew. He released Ajātasattu and did not harm him. Upon his return, the Buddha said (among other things) that Pasenadi "is a friend of virtue, acquainted with virtue, intimate with virtue", while the opposite is said of the aggressor, King Ajātasattu.

According to Theravada commentaries, there are five requisite factors that must all be fulfilled for an act to be both an act of killing and to be karmically negative. These are: (1) the presence of a living being, human or animal; (2) the knowledge that the being is a living being; (3) the intent to kill; (4) the act of killing by some means; and (5) the resulting death. Some Buddhists have argued on this basis that the act of killing is complicated, and its ethicality is predicated upon intent. Some have argued that in defensive postures, for example, the primary intention of a soldier is not to kill, but to defend against aggression, and the act of killing in that situation would have minimal negative karmic repercussions.

According to Babasaheb Ambedkar, there is circumstantial evidence encouraging from the Buddha's doctrine, "Love all, so that you may not wish to kill any." Gautama Buddha distinguished between a principle and a rule. He did not make a matter of rule, but suggested it as a matter of principle. This gives Buddhists freedom to act.

Laws
The emperors of the Sui dynasty, Tang dynasty, and early Song dynasty banned killing in the Lunar calendar's 1st, 5th, and 9th months. Empress Wu Tse-Tien banned killing for more than half a year in 692. Some rulers banned fishing for a period of time each year.

There were also bans after the death of emperors, after Buddhist and Taoist prayers, and after natural disasters such as Shanghai's 1926 summer drought, as well as an eight-day ban beginning August 12, 1959, after the August 7 flood (八七水災), the last big flood before the 88 Taiwan Flood.

People avoid killing during some festivals, like the Taoist Ghost Festival, the Nine Emperor Gods Festival, and the Vegetarian Festival, as well as during others.

Annals of Mathematics

The Annals of Mathematics is a mathematical journal published every two months by Princeton University and the Institute for Advanced Study.

History
The journal was established as The Analyst in 1874 and with Joel E. Hendricks as the founding editor-in-chief. It was "intended to afford a medium for the presentation and analysis of any and all questions of interest or importance in pure and applied Mathematics, embracing especially all new and interesting discoveries in theoretical and practical astronomy, mechanical philosophy, and engineering". It was published in Des Moines, Iowa, and was the earliest American mathematics journal to be published continuously for more than a year or two. This incarnation of the journal ceased publication after its tenth year, in 1883, giving as an explanation Hendricks' declining health, but Hendricks made arrangements to have it taken over by new management, and it was continued from March 1884 as the Annals of Mathematics. The new incarnation of the journal was edited by Ormond Stone (University of Virginia). It moved to Harvard in 1899 before reaching its current home in Princeton in 1911.

An important period for the journal was 1928–1958 with Solomon Lefschetz as editor. Norman Steenrod characterized Lefschetz' impact as editor as follows: "The importance to American mathematicians of a first-class journal is that it sets high standards for them to aim at. In this somewhat indirect manner, Lefschetz profoundly affected the development of mathematics in the United States."

Princeton University continued to publish the Annals on its own until 1933, when the Institute for Advanced Study took joint editorial control. Since 1998, it has been available in an electronic edition, alongside its regular print edition. The electronic edition was available without charge, as an open access journal, but since 2008, this is no longer the case. Issues from before 2003 were transferred to the non-free JSTOR archive, and articles are not freely available until 5 years after publication.

Abstracting and indexing
The journal is abstracted and indexed in the Science Citation Index, Current Contents/Physical, Chemical & Earth Sciences, and Scopus. According to the Journal Citation Reports, the journal has a 2020 impact factor of 5.246, ranking it third out of 330 journals in the category "Mathematics".

Andrei Sakharov

Andrei Dmitrievich Sakharov (Андрей Дмитриевич Сахаров; 21 May 1921 – 14 December 1989) was a Soviet physicist and a Nobel Peace Prize laureate, which he was awarded in 1975 for emphasizing human rights around the world.

Although he spent his career in physics in the Soviet program of nuclear weapons, overseeing the development of thermonuclear weapons, Sakharov also did fundamental work in understanding particle physics, magnetism, and physical cosmology. Sakharov is mostly known for his political activism for individual freedom, human rights, civil liberties and reforms in the Soviet Union, for which he was deemed a dissident and faced persecution from the Soviet establishment.

In his memory, the Sakharov Prize was established and is awarded annually by the European Parliament for people and organizations dedicated to human rights and freedoms.

Family background and early life
Andrei Dmitrievich Sakharov was born in Moscow on 21 May 1921, to a Russian family. His father, Dmitri Ivanovich Sakharov, was a physics professor at the Second Moscow State University and an amateur pianist. His grandfather, Ivan, was a lawyer in the former Russian Empire who had displayed respect for social awareness and humanitarian principles (including advocating the abolition of capital punishment). Sakharov's mother, Yekaterina Alekseevna Sofiano, was a daughter of Aleksey Semenovich Sofiano, a general in the Tsarist Russian Army with Greek heritage.

Sakharov's parents and paternal grandmother, Maria Petrovna, largely shaped his personality; his mother and grandmother were members of the Russian Orthodox Church, although his father was a non-believer. When Andrei was about thirteen, he realized that he did not believe in God. However, despite being an atheist, he did believe in a "guiding principle" that transcends the physical laws.

After schooling, Sakharov studied physics at the Moscow State University in 1938 and, following evacuation in 1941 during the Eastern Front with Germany, he graduated in Aşgabat in Turkmenistan. In 1943, he married Klavdia Alekseyevna Vikhireva, with whom he raised two daughters and a son. Klavdia would later die in 1969. In 1945, he joined the Theoretical Department of Physical Institute of the Russian Academy of Sciences under Igor Tamm in Moscow. In 1947, Sakharov was successful in defending his thesis for the Doctor of Sciences (lit. Doktor Nauk), which covered the topic of nuclear transmutation.

Soviet program of nuclear weapons
After World War II, he researched cosmic rays. In mid-1948 he participated in the Soviet atomic bomb project under Igor Kurchatov and Igor Tamm. Sakharov's study group at FIAN in 1948 came up with a second concept in August–September 1948. Adding a shell of natural, unenriched uranium around the deuterium would increase the deuterium concentration at the uranium-deuterium boundary and the overall yield of the device, because the natural uranium would capture neutrons and itself fission as part of the thermonuclear reaction. This idea of a layered fission-fusion-fission bomb led Sakharov to call it the sloika, or layered cake. The first Soviet atomic device was tested on August 29, 1949. After moving to Sarov in 1950, Sakharov played a key role in the development of the first megaton-range Soviet hydrogen bomb using a design known as Sakharov's Third Idea in Russia and the Teller–Ulam design in the United States. Before his Third Idea, Sakharov tried a "layer cake" of alternating layers of fission and fusion fuel. The results were disappointing, yielding no more than a typical fission bomb. However the design was seen to be worth pursuing because deuterium is abundant and uranium is scarce, and he had no idea how powerful the US design was. Sakharov realised that in order to cause the explosion of one side of the fuel to symmetrically compress the fusion fuel, a mirror could be used to reflect the radiation. The details had not been officially declassified in Russia when Sakharov was writing his memoirs, but in the Teller–Ulam design, soft X-rays emitted by the fission bomb were focused onto a cylinder of lithium deuteride to compress it symmetrically. This is called radiation implosion. The Teller–Ulam design also had a secondary fission device inside the fusion cylinder to assist with the compression of the fusion fuel and generate neutrons to convert some of the lithium to tritium, producing a mixture of deuterium and tritium. Sakharov's idea was first tested as RDS-37 in 1955. A larger variation of the same design which Sakharov worked on was the 50 Mt Tsar Bomba of October 1961, which was the most powerful nuclear device ever detonated.

Sakharov saw "striking parallels" between his fate and those of J. Robert Oppenheimer and Edward Teller in the US. Sakharov believed that in this "tragic confrontation of two outstanding people", both deserved respect, because "each of them was certain he had right on his side and was morally obligated to go to the end in the name of truth." While Sakharov strongly disagreed with Teller over nuclear testing in the atmosphere and the Strategic Defense Initiative, he believed that American academics had been unfair to Teller's resolve to get the H-bomb for the United States since "all steps by the Americans of a temporary or permanent rejection of developing thermonuclear weapons would have been seen either as a clever feint, or as the manifestation of stupidity. In both cases, the reaction would have been the same – avoid the trap and immediately take advantage of the enemy's stupidity."

Sakharov never felt that by creating nuclear weapons he had "known sin", in Oppenheimer's expression. He later wrote: "After more than forty years, we have had no third world war, and the balance of nuclear terror ... may have helped to prevent one. But I am not at all sure of this; back then, in those long-gone years, the question didn't even arise. What most troubles me now is the instability of the balance, the extreme peril of the current situation, the appalling waste of the arms race ... Each of us has a responsibility to think about this in global terms, with tolerance, trust, and candor, free from ideological dogmatism, parochial interests, or national egotism.'"

Support for peaceful use of nuclear technology
In 1950 he proposed an idea for a controlled nuclear fusion reactor, the tokamak, which is still the basis for the majority of work in the area. Sakharov, in association with Tamm, proposed confining extremely hot ionized plasma by torus shaped magnetic fields for controlling thermonuclear fusion that led to the development of the tokamak device.

Magneto-implosive generators
In 1951 he invented and tested the first explosively pumped flux compression generators, compressing magnetic fields by explosives. He called these devices MK (for MagnetoKumulative) generators. The radial MK-1 produced a pulsed magnetic field of 25 megagauss (2500 teslas). The resulting helical MK-2 generated 1000 million amperes in 1953.

Sakharov then tested a MK-driven "plasma cannon" where a small aluminum ring was vaporized by huge eddy currents into a stable, self-confined toroidal plasmoid and was accelerated to 100 km/s. Sakharov later suggested replacing the copper coil in MK generators with a large superconductor solenoid to magnetically compress and focus underground nuclear explosions into a shaped charge effect. He theorized this could focus 1023 protons per second on a 1 mm2 surface.

Particle physics and cosmology
After 1965 Sakharov returned to fundamental science and began working on particle physics and physical cosmology. He tried to explain the baryon asymmetry of the universe; in that regard, he was the first to give a theoretical motivation for proton decay. Proton decay was suggested by Wigner in 1949 and 1952. Proton decay experiments had been performed since 1954 already. Sakharov was the first to consider CPT-symmetric events occurring before the Big Bang:"We can visualize that neutral spinless maximons (or photons) are produced at t  < 0 from contracting matter having an excess of antiquarks, that they pass 'one through the other' at the instant  t  = 0 when the density is infinite, and decay with an excess of quarks when  t  > 0, realizing total CPT symmetry of the universe. All the phenomena at t < 0 are assumed in this hypothesis to be CPT reflections of the phenomena at t > 0." His legacy in this domain are the famous conditions named after him: Baryon number violation, C-symmetry and CP-symmetry violation, and interactions out of thermal equilibrium.

Sakharov was also interested in explaining why the curvature of the universe is so small. This led him to consider cyclic models, where the universe oscillates between contraction and expansion phases. In those models, after a certain number of cycles the curvature naturally becomes infinite even if it had not started this way: Sakharov considered three starting points, a flat universe with a slightly negative cosmological constant, a universe with a positive curvature and a zero cosmological constant, and a universe with a negative curvature and a slightly negative cosmological constant. Those last two models feature what Sakharov calls a reversal of the time arrow, which can be summarized as follows: He considers times t > 0 after the initial Big Bang singularity at t = 0 (which he calls "Friedman singularity" and denotes Φ) as well as times t < 0 before that singularity. He then assumes that entropy increases when time increases for t > 0 as well as when time decreases for t < 0, which constitutes his reversal of time. Then he considers the case when the universe at t < 0 is the image of the universe at t > 0 under CPT symmetry but also the case when it is not so: the universe has a non-zero CPT charge at t = 0 in this case. Sakharov considers a variant of this model where the reversal of the time arrow occurs at a point of maximum entropy instead of happening at the singularity. In those models there is no dynamic interaction between the universe at t 0.

In his first model the two universes did not interact, except via local matter accumulation whose density and pressure become high enough to connect the two sheets through a bridge without spacetime between them, but with a continuity of geodesics beyond the Schwarzschild radius with no singularity, allowing an exchange of matter between the two conjugated sheets, based on an idea after Igor Dmitriyevich Novikov. Novikov called such singularities a collapse and an anticollapse, which are an alternative to the couple black hole and white hole in the wormhole model. Sakharov also proposed the idea of induced gravity as an alternative theory of quantum gravity.

Turn to activism
Since the late 1950s Sakharov had become concerned about the moral and political implications of his work. Politically active during the 1960s, Sakharov was against nuclear proliferation. Pushing for the end of atmospheric tests, he played a role in the 1963 Partial Test Ban Treaty, signed in Moscow.

Sakharov was also involved in an event with political consequences in 1964, when the Soviet Academy of Sciences nominated for full membership Nikolai Nuzhdin, a follower of Trofim Lysenko (initiator of the Stalin-supported anti-genetics campaign Lysenkoism). Contrary to normal practice, Sakharov, a member of the academy, publicly spoke out against full membership for Nuzhdin and held him responsible for "the defamation, firing, arrest, even death, of many genuine scientists." In the end, Nuzhdin was not elected, but the episode prompted Nikita Khrushchev to order the KGB to gather compromising material on Sakharov.

The major turn in Sakharov's political evolution came in 1967, when anti-ballistic missile defense became a key issue in US–Soviet relations. In a secret detailed letter to the Soviet leadership of July 21, 1967, Sakharov explained the need to "take the Americans at their word" and accept their proposal for a "bilateral rejection by the USA and the Soviet Union of the development of antiballistic missile defense" because an arms race in the new technology would otherwise increase the likelihood of nuclear war. He also asked permission to publish his manuscript, which accompanied the letter, in a newspaper to explain the dangers posed by that kind of defense. The government ignored his letter and refused to let him initiate a public discussion of ABMs in the Soviet press.

Since 1967, after the Six Day War and the beginning of the Arab-Israeli conflict, he actively supported Israel, as he reported more than once in the press, and also maintained friendly relations with refuseniks who later made aliyah.

In May 1968, Sakharov completed an essay, "Reflections on Progress, Peaceful Coexistence, and Intellectual Freedom". He described the anti-ballistic missile defense as a major threat of world nuclear war. After the essay was circulated in samizdat and then published outside the Soviet Union, Sakharov was banned from conducting any military-related research and returned to FIAN to study fundamental theoretical physics.

For 12 years, until his exile to Gorky (Nizhny Novgorod) in January 1980, Sakharov assumed the role of a widely recognized and open dissident in Moscow. He stood vigil outside closed courtrooms, wrote appeals on behalf of more than 200 individual prisoners, and continued to write essays about the need for democratization.

In 1970, Sakharov was among the three founding members of the Committee on Human Rights in the USSR, along with Valery Chalidze and Andrei Tverdokhlebov. The Committee wrote appeals, collected signatures for petitions and succeeded in affiliating with several international human rights organizations. Its work was the subject of many KGB reports and brought Sakharov under increasing pressure from the government.

Sakharov married a fellow human rights activist, Yelena Bonner, in 1972.

By 1973, Sakharov was meeting regularly with Western correspondents and holding press conferences in his apartment. He appealed to the US Congress to approve the 1974 Jackson-Vanik Amendment to a trade bill, which coupled trade tariffs to the Kremlin's willingness to allow freer emigration for Soviet Jews.

Attacked by Soviet establishment from 1972
In 1972, Sakharov became the target of sustained pressure from his fellow scientists in the Soviet Academy of Sciences and the Soviet press. The writer Aleksandr Solzhenitsyn came to his defence.

In 1973 and 1974, the Soviet media campaign continued, targeting both Sakharov and Solzhenitsyn for their pro-Western, anti-socialist positions.

Sakharov later described that it took "years" for him to "understand how much substitution, deceit, and lack of correspondence with reality there was" in the Soviet ideals. "At first I thought, despite everything that I saw with my own eyes, that the Soviet State was a breakthrough into the future, a kind of prototype for all countries". Then he came, in his words, to "the theory of symmetry: all governments and regimes to a first approximation are bad, all peoples are oppressed, and all are threatened by common dangers.":

"...symmetry between a cancer cell and a normal one. Yet our state is similar to a cancer cell – with its messianism and expansionism, its totalitarian suppression of dissent, the authoritarian structure of power, with a total absence of public control in the most important decisions in domestic and foreign policy, a closed society that does not inform its citizens of anything substantial, closed to the outside world, without freedom of travel or the exchange of information."

Sakharov's ideas on social development led him to put forward the principle of human rights as a new basis of all politics. In his works, he declared that "the principle 'what is not prohibited is allowed' should be understood literally", and defied what he saw as unwritten ideological rules imposed by the Communist Party on the society in spite of a democratic Soviet Constitution (1936): "I am no volunteer priest of the idea, but simply a man with an unusual fate. I am against all kinds of self-immolation (for myself and for others, including the people closest to me)."

In a letter written from exile, he cheered up a fellow physicist and free market advocate with the words: "Fortunately, the future is unpredictable and also – because of quantum effects – uncertain." For Sakharov, the indeterminacy of the future supported his belief that he could and should take personal responsibility for it.

Nobel Peace Prize (1975)
In 1973, Sakharov was nominated for the Nobel Peace Prize, and in 1974, he was awarded the Prix mondial Cino Del Duca.

Sakharov was awarded the Nobel Peace Prize in 1975. The Norwegian Nobel Committee called him "a spokesman for the conscience of mankind". In the words of the Nobel Committee's citation: "In a convincing manner Sakharov has emphasised that Man's inviolable rights provide the only safe foundation for genuine and enduring international cooperation."

Sakharov was not allowed to leave the Soviet Union to collect the prize. His wife, Yelena Bonner, read his speech at the ceremony in Oslo, Norway. On the day the prize was awarded, Sakharov was in Vilnius, where the human rights activist Sergei Kovalev was being tried. In his Nobel lecture, "Peace, Progress, Human Rights", Sakharov called for an end to the arms race, greater respect for the environment, international cooperation, and universal respect for human rights. He included a list of prisoners of conscience and political prisoners in the Soviet Union and stated that he shared the prize with them.

By 1976, the head of the KGB, Yuri Andropov, was prepared to call Sakharov "Domestic Enemy Number One" before a group of KGB officers.

Internal exile (1980–1986)
Sakharov was arrested on 22 January 1980, following his public protests against the Soviet intervention in Afghanistan in 1979, and was sent to the city of Gorky, now Nizhny Novgorod, a city that was off limits to foreigners.

Between 1980 and 1986, Sakharov was kept under Soviet police surveillance. In his memoirs, he mentioned that their apartment in Gorky was repeatedly subjected to searches and heists. Sakharov was named the 1980 Humanist of the Year by the American Humanist Association.

In May 1984, Sakharov's wife, Yelena Bonner, was detained, and Sakharov began a hunger strike, demanding permission for his wife to travel to the United States for heart surgery. He was forcibly hospitalized and force-fed. He was held in isolation for four months. In August 1984, Bonner was sentenced by a court to five years of exile in Gorky.

In April 1985, Sakharov started a new hunger strike for his wife to travel abroad for medical treatment. He again was taken to a hospital and force-fed. In August, the Politburo discussed what to do about Sakharov. He remained in the hospital until October 1985, when his wife was allowed to travel to the United States. She had heart surgery in the United States and returned to Gorky in June 1986.

In December 1985, the European Parliament established the Sakharov Prize for Freedom of Thought, to be given annually for outstanding contributions to human rights.

On 19 December 1986, Mikhail Gorbachev, who had initiated the policies of perestroika and glasnost, called Sakharov to tell him that he and his wife could return to Moscow.

Political leader
In 1988, Sakharov was given the International Humanist Award by the International Humanist and Ethical Union. He helped to initiate the first independent legal political organizations and became prominent in the Soviet Union's growing political opposition. In March 1989, Sakharov was elected to the new parliament, the All-Union Congress of People's Deputies and co-led the democratic opposition, the Inter-Regional Deputies Group. In November the head of the KGB reported to Gorbachev on Sakharov's encouragement and support for the coal miners' strike in Vorkuta.

In December 1988, Sakharov visited Armenia and Azerbaijan on a fact-finding mission. He concluded, "For Azerbaijan the issue of Karabakh is a matter of ambition, for the Armenians of Karabakh, it is a matter of life and death".

Death
Soon after 9 p.m. on 14 December 1989, Sakharov went to his study to take a nap before preparing an important speech he was to deliver the next day in the Congress. His wife went to wake him at 11pm as he had requested but she found Sakharov dead on the floor. According to the notes of Yakov Rapoport, a senior pathologist present at the autopsy, it is most likely that Sakharov died of an arrhythmia consequent to dilated cardiomyopathy at the age of 68. He was interred in the Vostryakovskoye Cemetery in Moscow.

Memorial prizes
The Sakharov Prize for Freedom of Thought was established in 1988 by the European Parliament in his honour, and is the highest tribute to human rights endeavours awarded by the European Union. It is awarded annually by the parliament to "those who carry the spirit of Soviet dissident Andrei Sakharov"; to "Laureates who, like Sakharov, dedicate their lives to peaceful struggle for human rights."

An Andrei Sakharov prize has also been awarded by the American Physical Society every second year since 2006 "to recognize outstanding leadership and/or achievements of scientists in upholding human rights".

The Andrei Sakharov Prize for Writer's Civic Courage was established in October 1990.

In 2004, with the approval of Yelena Bonner, an annual Sakharov Prize for journalism was established for reporters and commentators in Russia. Funded by former Soviet dissident Pyotr Vins, now a businessman in the US, the prize is administered by the Glasnost Defence Foundation in Moscow. The prize "for journalism as an act of conscience" has been won over the years by famous journalists such as Anna Politkovskaya and young reporters and editors working far from Russia's media capital, Moscow. The 2015 winner was Yelena Kostyuchenko.

Andrei Sakharov Archives and Human Rights Center
The Andrei Sakharov Archives and Human Rights Center, established at Brandeis University in 1993, are now housed at Harvard University. The documents from that archive were published by the Yale University Press in 2005. These documents are available online. Most of documents of the archive are letters from the head of the KGB to the Central Committee about activities of Soviet dissidents and recommendations about the interpretation in newspapers. The letters cover the period from 1968 to 1991 (Brezhnev stagnation). The documents characterize not only Sakharov's activity, but that of other dissidents, as well as that of highest-position apparatchiks and the KGB. No Russian equivalent of the KGB archive is available.
