Talk:Colors of noise

''Warning: Some of these seem to originate exclusively from a single newsgroup posting from October 1996 by Joseph S. Wisniewski, and should be considered questionable. The nature of the wiki will cause the definitions to converge towards the true definitions with time, making this article more accurate than the copies of that posting. Providing references for each will help with this.''

Measurement 'noise'
This article seems to focus only on noise in terms of sound and maybe electronics. Where should something be included about noise (as a source of error) in making measurements - whether from technical or experimental source material? Of course, the same power/frequency concepts apply. Pat Heslop-Harrison 07:43, 21 May 2006 (UTC)

Real definitions
we could expand all of these to use the 1/fβ notation, where β = something, as used in some of these examples. — Omegatron

"The Federal Standard 1037C Telecommunications: Glossary of Telecommunication Terms defines four noise colors (white, pink, blue & black) and is considered the official source."

 * An official source, perhaps but any one nation's standards can't be taken to be the standard. Is there any ISO standard, for example?  I'd have thought a lot of this information is worth putting onto the main page, BTW.  --Douglas 4 July 2005 15:17 (UTC)

 * It's better than a newsgroup posting. Here are the official definitions:

 * white noise : Noise having a frequency spectrum that is continuous and uniform over a specified frequency band. (188) Note: White noise has equal power per hertz over the specified frequency band. Synonym  additive white gaussian noise.
 * pink noise : In acoustics, noise in which there is equal power per octave.
 * black noise : Noise that has a frequency spectrum of predominately zero power level over all frequencies except for a few narrow bands or spikes. Note: An example of black noise in a facsimile transmission system is the spectrum that might be obtained when scanning a black area in which there are a few random white spots. Thus, in the time domain, a few random pulses occur while scanning.
 * blue noise : In a spectrum of frequencies, a region in which the spectral density, i.e., power per hertz, is proportional to the frequency.

Maybe it should read "Purple noise" because "Orange noise" isn't listed below. I don't know. I guess it's a matter of precision that I don't know about. Peter 03:51, 4 December 2006 (UTC)

 * An industry standard may be considered "official" by those working in that particular industry, but to people in other fields it is just an arbitrary choice like any other. So instead of "official" and "unofficial" this article should say explicitly "according to the FS 1037C Glossary" for the first, and "informal" and/or "occasionally used" for the second. --Jorge Stolfi (talk) 13:19, 13 February 2013 (UTC)

Red
red = brown (1/f2) definition:

A mean reverting stochastic process http://riskinstitute.ch/00012612.htm

A stationary and causal Gaussian first order autoregressive (AR(1)) process {Xt} with mean zero (a real oceanographic definition) http://faculty.washington.edu/dbp/PDFFILES/red-noise.pdf

Geophysical processes, for example, are often characterized by red noise backgrounds. For red noise, the variance decreases with increasing frequency. In some cases, the overall noise trend can be approximated by a first order AR model. http://www.systat.com/products/TableCurve2D/help/?sec=1080

http://www.atmos.ucla.edu/~csi/REF/pdfs/ensomjo.pdf

I have a feeling red and brown are actually the same, and red/brown is used as a model for oceanographic research. In other words, the ocean-filtered noise is not red, but is modeled by red? - Omegatron 15:54, Jun 6, 2005 (UTC)

Why put up examples that can't be played with Quicktime, Real or MS?
 * Using Ogg Vorbis files is Wikipedia policy. There's a handy help link next to each one that will tell you how to configure your player to play them. Wikipedia uses Vorbis because it's not patent encumbered, the standard is totally open, and therefore it is the most likely to a) be usable far into the future when current formats die out, b)have a player for virtually any platform a user might be using, and c) isn't patent encumbered and thus Wikimedia can legally use any free encoders that exist --Ktims 00:56, 28 March 2006 (UTC)

Black
Most environmental noise is reddened: the variation is dominated by long-term £uctuations. Recent modelling has shown that moderately reddened noise a¡ects populations di¡erently from the white noise used in earlier studies. However, some geophysical phenomena, such as temperature and river height, can have deeply reddened `brown' or even `black' spectra http://oak.cats.ohiou.edu/~cuddingt/pubs/proceedings99.pdf

Green noise
So why is there supposedly a 500 Hz hump in "green noise"? Rotation of the ether? --Chinasaur 00:50, 16 Jun 2005 (UTC)

 * Who knows? Original newsgroup post said "Green noise (defined by some folks producing relaxation tapes, Mystic Moods, I believe)".  I don't know why this was removed. - Omegatron 01:36, Jun 16, 2005 (UTC)

Grey noise sample?
Great article, folks :-) Is anybody working on a sample of grey noise to complement the others - cause otherwise I might try to create one. Peter S. 10:20, 26 September 2005 (UTC)

 * Huh. I was going to do that.  Must have forgotten.  Feel free.  I was just going to take white noise and FFT filter it in cool edit/audition, plugging in values from the weighting filter a-weighting equation.  There's probably a better way.  — Omegatron 13:51, 26 September 2005 (UTC)

 * No, just go ahead, I would have to search for an ogg encoder first, you seem to be already set up. Cheers :-) Peter S. 14:37, 26 September 2005 (UTC)

 * Alright, I'll try to remember to do it tonight. — Omegatron 16:39, 26 September 2005 (UTC)

 * Cool, many happy thanks :-) Peter S. 17:18, 26 September 2005 (UTC)

 * Oh, I remember why I never did this. Since it's the inverse of a weighting filter, and a weighting filter tends towards −∞ dB, the signal will tend towards +∞ dB at the frequency extremes.  So I didn't really know how to weight it and still have a decent signal level.  If I chose the range from 10 Hz to 20 kHz, for instance, the level at 10 Hz would be 0 dB, and the level at 1 kHz would be -70 dB.  — Omegatron 21:02, 26 September 2005 (UTC)

 * Good point. (EDIT) I'd create a version of 20Hz-20kHz@16bit (19Hz would be the lowest frequency great cinema subwoofers output). At this range, you've got 55 dB between 20 Hz and 1kHz, plenty enough in 16bit space (~96dB). 24bit would give you a better s/n ratio, of course, but is it really necessary to have a low noise floor on a sound file that is essentially noise? :-) And in any case, add that disclaimer to the article. At least that's what I would do. Cheers! Peter S. 23:20, 26 September 2005 (UTC)

 * Oh, here it is. Sounds good, many thanks :-) Peter S. 09:39, 27 September 2005 (UTC)

 * Yeah, these are just approximations. I guess it all gets lost in the ogg conversion anyway, so it doesn't matter, but I was thinking of making it perfect, taking real random numbers from random.org, converting to sound file (I got this far last night before realizing it wasn't really worth it), making gaussian distributed, save as white noise, integrate in matlab or something (instead of FFT filter approximation), normalize, save as brown noise, etc. etc.    If we could upload WAV files as well as listenable files I could see how this could be useful for posterity kind of reasons; do everything exactly so other people can use the files for other purposes, but for now it's silly overkill.  — Omegatron 14:04, 27 September 2005 (UTC)

 * We can indeed upload lossless files, I have discovered, by encoding as ogg FLAC. I might go through and do it again sometime with perfect random numbers and mathematical accuracy.  But not today.  I'm not sure what it would accomplish, even, but it would be interesting to do... — Omegatron 00:45, 19 June 2006 (UTC)

Too complex
I'm not a physicist and understand almost none of this, could some of it be explained or simplified somehow? Fantom 17:36, 27 November 2005 (UTC)

 * Well, maybe we could add a graph of the audio spectrum for all the "noise colors" to make it easier to understand? Peter S. 18:36, 27 November 2005 (UTC)

 * Pictures would be very good. — Omegatron 00:53, 1 December 2005 (UTC)
 * I've added some simple spectrum analyses to the page, but the only source data I have is the .ogg files, so it's probably severely distorted from what a real graph would look like. I don't have the software handy (or the background knowledge/maths) to generate new files for some of the more exotic noises. If I get the .wav files, I'll improve them. Aside from Brown and perhaps Grey though, they look pretty good. --Ktims 14:27, 13 March 2006 (UTC)

 * Those are very good. I was going to make some, but yours are better.
 * I have the original wav files, and can send them to you if you'd like (send me an email). The spectra won't be much different except at high frequencies, but I like accuracy, too.
 * I'd like them better if they were log-frequency dB-amplitude, to show the "straight lineness" of the spectra.
 * Your gnuplot diagrams look better than mine. I'd like to know how you made them.  :-)  It's helpful to put some info about how you made things on the image description page so that others can reproduce it, translate labels into their own language, etc.  You're also supposed to upload diagrams in SVG format whenever possible, though gnuplot's SVG output doesn't look so great, in my opinion.  Example: Image:Waveforms.svg vs Image:Waveforms.png.  I'm still uploading them in PNG until either 1. the SVG rendering gets better or 2. I learn to produce better SVGs.  — Omegatron 16:20, 13 March 2006 (UTC)

Sample encoding
Doesn't the OGG encoding of the samples use psychoacoustic modelling? And wouldn't that severely distort the result, considering that grey noise is based on psychoacoustics itself? Using uncompressed or losslessly compressed sample would IMO be vastly preferable. --Brazzy 11:13, 30 November 2005 (UTC)

 * Yep. I have the original wav files still, but Wikipedia only accepts ogg.  It's not a bad approximation for now. — Omegatron 14:09, 30 November 2005 (UTC)

 * forgive my stupidy on the subject.. but in using psychoacoustic modelling surely it would _sound_ the same to a human and that's what's important right? if you were going to use them for anything wouldn't you have software / equipment to generate them? --Streaky 01:34, 11 September 2006 (UTC)

 * Theoretically, yeah, but psychoacoustic modelling isn't really meant for pure noise, and throws away information that distorts the sound. Apparently you can pack pure WAV files into the ogg container, so I might do that if I get around to it someday and upload it separately... — Omegatron 04:47, 11 September 2006 (UTC)

Layout?
Now that we've got frequency graphs, it would be useful to give more significance to the layout of the page, to ensure that the graphs and their descriptions stay aligned. I'm not a Wiki or HTML expert...any takers on this? --Ktims 02:15, 14 March 2006 (UTC)

 * You can add clear after each definition if you want. Is it possible to make the brown and purple fill up the entire x axis?  Or do the others look ugly on the same scale? — Omegatron 03:35, 14 March 2006 (UTC)
 * I just tried it out, and unfortunately increasing the vertical range flattens the pink and brown curves out so much that they look too close. I may recreate the charts with gnuplot's 'smooth bezier' option when I get time, they look a lot less erratic, and for these purposes that's better IMO.

Why do you keep removing it? Its a legit WP construct is it not? Pls resond on Project Electronics as we have the same problem of organising our articles. If we dont start it soon, it will become a massive task--Light current 05:18, 5 April 2006 (UTC)

Shot noise
So where does shot noise fit in this scheme? I have reservations about the color-to-name scheme because I personally have heard only about white noise and pink noise (especially the uniform spectrum part). And what about Johnson noise, for that matter. What if these articles don't have a cited noise-to-color correspondence? --Ancheta Wis 20:41, 18 June 2006 (UTC)

 * According to Johnson-Nyquist_noise, it's white. Shot noise doesn't specify, but this external link says it's white as well.  The colors have nothing to do with the process that produced the noise; they're just descriptions of the frequency spectrum produced. — Omegatron 00:42, 19 June 2006 (UTC)

 * See Talk:Electronic noise. — Omegatron 04:47, 11 September 2006 (UTC)

 * Beware that the power spectrum does not define the sinal; many completely different signals have identical power spectra. Shot noise in particular has a time-domain description that makes it very different from white noise even though it too has (or may have) flat power spectrum. Also, "noise" for this article means "a meaningless random signal", whereas in other signal processing articles it means "an unwanted distortion of a signal"; which need not be the addition of some "meaningless random signal". --Jorge Stolfi (talk) 13:08, 13 February 2013 (UTC)

Origin
How did this whole spectrum → color thing start, anyway? Was "white noise" coined first, to make an analogy to white light with all the colors of the spectrum present? Was "Brownian noise" coined first, named for Brownian motion, but then corrupted into a color abbreviation and followed by others? — Omegatron 17:57, 24 October 2006 (UTC)

American Heritage Dictionary just says: "[From the analogy with white light.]"

From the article:

''The color names for these different types of sounds are derived from a loose analogy between the spectrum of frequencies of sound wave present in the sound (as shown in the blue diagrams) and the equivalent spectrum of light wave frequencies. That is, if the sound wave pattern of "blue noise" were translated into light waves, the resulting light would be blue, and so on.''

Can we get a reference on that? Brown noise, for instance, was not named for the color, and the colors listed do not actually correspond with the actual color spectrum. — Omegatron 04:37, 4 December 2006 (UTC)

what does 'DC' mean in the explanation of Brown noise?
The term 'DC' is not defined and I could not quickly determine its meaning via google or the disambiguation page here on wikipedia... could any help? Kinser 03:20, 18 January 2007 (UTC)

 * Direct current, or a signal with a frequency of zero. — Omegatron 21:48, 18 March 2007 (UTC)

Removed Mains hum section
Sorry for being a party pooper, but I've removed the mains hum section. I'm sad to say, but it is not a colour, as the title of the article tells me, and there is an article named Mains hum. Also, it isn't a pure noise (i.e., it isn't "a random signal", as the first paragraph of the article says), I hope everyone is okay with that. I'll move the relevant discussion to Talk:Mains hum now. +mwtoews 08:50, 8 February 2007 (UTC)

structuredness

Graphs meaning for laymen
Sorry if I'm being dumb here, but I'm struggling to understand how the graphs, particularly of white v pink noise, relate to their descriptions. White noise is described as having a flat frequency spectrum in linear space, but the graph shows a (roughly) flat spectrum with a logarithmic scale. Pink noise is described as being "flat in logarithmic space", but its graph shows a downward trend on the same log scale. I'm guessing that the y-axis of the graphs (dB) is not what they are "flat" in (ie power?), but it all seems horribly confusing. Also the slight rise in the white noise graph is attributed to it being a log rather than linear scale, but that can't be right, if it were on a linear scale it would surely slope downwards dramatically -- so it seems more like the slight rise is an aberration and this isn't true white noise (hardly surprising if it was generated from an OGG file...) Can anyone shed some light? Thanks. 217.169.15.38 19:23, 11 October 2007 (UTC)

 * Yes, you are quite correct. The plots are obviously wrong, and should be corrected or removed. Furthermore, a grey noise curve can only be correct for one absolute level in dBSPL (e.g. dB(A) is only valid for 40dB@1kHz, or -54dBPa@1kHz) and will look more like the white noise as the absolute level increases. Therefore it is questionable if such a graph is of any help without a more stringent (correct) explanation.— DrD 00:08, 10 November 2007 (UTC)

The y axis of the graphs is logarithmic. dB are logarithmic. Maybe it would be better to have two axes, one log (1, 10, 100, 1000) and the opposing axis in dB, to make this clear.

The x axis is logarithmic, but the measurement is from an FFT, so the measurement bin divisions are linear. I see how this could be confusing, but the angled straight line spectrums will not show up unless they are plotted on a log-log plot.

Hmm... The slight rise in the white noise appears in Adobe Audition, too, which I think was performed on the original wave file. Could be an artifact of Audition's white noise generator (aliasing?), an artifact of the measurement method, or an artifact of the way it's plotted.

Also, is the grey noise completely wrong? I used white noise and filtered it with an inverted A-weighting curve. But maybe it should have started with pink noise?

It would be better if both the signals and the analysis were generated purely in mathematics software (GNU Octave), rather than audio software, but I never got around to this. — Omegatron (talk) 15:38, 12 April 2008 (UTC)

Relevance of analogies between sound and light
In some aspects sound and light are not even considered to have any relationship, but in some cases the two phenomena can be represented with similar models. An example of the latter case is that a sampling in the time domain of the respective field variables of the both phenomena could be Fourier transformed to the frequency domain and be represented as (e.g.) energy distribution vs frequency. Since different distributions of light energy vs frequency can be interpreted as different colours (which is a very obvious interpretation), it is very tempting to do an analogy with sound. But, since sound and light are perceived totally different, it does not make much sense to do a translation of colours to sounds, apart from in some (actually very few) cases:

Evenly distributed noise (in a linear sense, i.e. perfectly random noise) can be called white and the logarithmically distributed counterpart can be called pink in order to suggest that the energy in the low frequency region is dominating in the latter case. The same line of reasoning can be applied for blue light/noise (a domination of high frequency contents) and for black light/noise (absense of energy throughout the whole frequency range, which does not seem as much of a "help" for visualising the nature of the noise - it is kind of obvious anyway). These definitions can be seen as "standard" definitions, are more or less well-established and give a good picture of how the noise is distributed in each case.

But when it comes to the other colours than these mentioned it is not possible to make an obvious and unique interpretation. Neither will these interpretation be of any help. In the best of scenarios we have some academic interpretations that will not help by giving any "feeling" of what kind of noise it is. A nonsense name would be equally sufficient. In the worst scenario we have some childish and far-fetched attempts to make analogies that are both misleading and non-intuitive.

For example: Brown noise is not even an analogy to the corresponding colour. Furthermore, if brown noise is considered as a result of Brownian motion, then the energy distribution is a result of how you implement the random walk amplitude and frequency wise. The resulting distribution can be totally different from what is stated here (the definition here is as meaningful as claiming that the top speed of a car is twice the top speed of a bus). Also the usefulness of such noise can be doubted. Nevertheless, this definition has some merits, mostly because it has been around for some time. Red noise actually implies absence of high frequency contents (dark pink had been more appropriate...) Purple noise is maybe relevant, but it should in that case replace the blue noise definition, which in analogy to the pink noise actually should be called light blue... The grey noise definition contradicts the notion of white noise being perceived as white. Furthermore, its energy distribution should, according to how it is defined here, be a function of the absolute sound pressure level. It will therefore be meaningless nonsense in a file, as a electrical signal and so on unless it is played back at a corresponding calibrated level. These colours, plus orange, green and so on, are all more or less unnecessary constrained constructions.

Thus, if there is no motive to invent new non-standard noise-colour analogies: Please refrain from creating or promoting personal home-made definitions! It only gives too much importance to an analogy which is not inuitive - does anyone really think there is a common notion of, for example, how "green" would sound? –– DrD 22:29, 9 November 2007 (UTC)

 * These abrownre not "home-made definitions". They are taken right out of Federal Standard 1037C.  I changed the "brown" heading to "red" because it fits in more with the colors theme. — Omegatron (talk) 15:57, 12 April 2008 (UTC)

 * Yes, there are some definitions that are established. I have no problem with them. I had to check in Federal Standard 1037C (http://www.its.bldrdoc.gov/fs-1037/fs-1037c.htm), and I did find the ordinary "white", "pink", "blue" and "black" definitions in their A-Z list. No "brown", "green", "red", "violet" et cetera. Being in the Telecom biz myself, I find it hard to imagine why Federal Standard 1037C should bother to distinguish between e.g. "green", and "orange" noise. Still I find reason to discuss and write about e.g. "brown" and "red" noise. But my point was that I think there is no merit in taking the sound and light analogy too far, since there is so much assumptions to be made before you actually get e.g green, or purple light when you make a translation from sound energy.192.16.134.69 (talk) 08:45, 6 November 2009 (UTC) DrD

White noise amplitudes
I started the process of re-generating all the noise audio samples from scratch in GNU Octave. So far I've just got Image:White noise.ogg (uniformly distributed) and Image:Gaussian white noise.ogg (normally distributed).

The Gaussian file sounds about 4.5 dB quieter than the uniformly-distributed file, while SoX says they are actually 8.4 dB different. Is this psychoacoustics or did I measure something wrong? — Omegatron (talk) 04:58, 21 April 2008 (UTC)

Equal energy versus equal perceptual ammount
White audio noise sounds like a high-frequency hiss; white image noise looks like static and can perceptually be removed with a low-pass filter. Could someone explain the difference between the definition of white noise and this intuitive sense that white noise is a high-frequency noise? I assume it has to do with the difference between energy and amplitude of a frequency band and that blue or violet noise would be perceptually uniform across the spectrum (and so wouldn't be removed easily by a low-pass filter). —Ben FrantzDale (talk) 15:18, 15 September 2008 (UTC)

Too specific
"red noise" has ended up linked from a cliamte page. But the defn here is far far too specific. "red noise" (no-one uses brown) from the climate point of view is just noise with more power at lower frequencies. None of this 6-db-per-whatever stuff William M. Connolley (talk) 21:02, 16 September 2008 (UTC)

Black noise -- a joke?
I'm not questioning whether the entirety of the "black noise" description is a joke, just a part of it. The article says:

 * Used in modeling various environmental processes. Is said to be a characteristic of "natural and unnatural catastrophes like floods, droughts, bear markets, and various outrageous outages, such as those of electrical power." Further, "because of their black spectra, such disasters often come in clusters."

and cites Manfred Schroeder's book _Fractals, chaos, power laws_. I don't have this book and Amazon won't let me search it. Basically I'm wondering if this description is some kind of joke about power outages during natural disasters.

 * Rose plays with language, has fun with words, and uses "black noise" playfully rather than in a way that can help define the term. Rose does not define it. She also uses the term TRSOB; another playful bit that is not helpful to an encyclopedia. Binksternet (talk) 13:45, 17 August 2011 (UTC)

Infinite sums can approach a limit
Seeking comments before I strike this sentence:

 * Err no. That is a pile of symbols with no meaning.

What noise is heard on FM tuner?
What noise is heard on FM radio tuned to clear frequency? —Preceding unsigned comment added by Boskoigic (talk • contribs) 19:36, 3 February 2010 (UTC)
 * Mostly white, I think. —Ben FrantzDale (talk) 12:56, 4 February 2010 (UTC)

 * That is not really white noise. FM in-between-station noise is shaped by variables that differ by FM frequency, receiver location, the number of radio stations packing the airwaves, receiver circuit design, loudspeaker capability, etc... a wide range of elements all having an affect on the noise. Sometimes there are voices or music faintly detectable amid the noise—the frequency is not really clear. Most relevant is that the sound will be reproduced by loudspeakers or headphones when you hear it, meaning that it will be band-limited to the frequency range of the playback system. As well, the noise will have a steep filter preventing sounds higher than 16 kHz, typical of FM reception. There's no particular color assigned to this kind of noise. Binksternet (talk) 17:05, 4 February 2010 (UTC)

Physics implications of different colours of noise
I think the article should explain not only what are the colours of noise but also the implications. You often hear physicists referring to different colours of noise so IMHO an explanation of the implications would be useful.

Spectrum vs. spectral density
It must be noted that the spectrum (FFT output, dB, amplitudes) and the spectral density has different units and thus also noise slopes. Pink noise figure - in dB (not in dB/rootHz) but the spectral density stated. White noise - flat spectrum (not spectral density) - http://www.1w.net/nyu/wnoise.html. This article must be rewritten!

brown noise
brown noise can refer to noise that is a frequency that moves the bowels, this should be under unofficial colours 188.223.18.19 (talk) 19:25, 17 March 2012 (UTC)

 * No, that notional noise is brown note and it has its own page. It is not real, so it does not need to be mentioned here. Binksternet (talk) 19:46, 17 March 2012 (UTC)

Article name should be "Noise color" or "Color of noise"
As a general rule, the name of a Wikipedia article should be a singular noun. E.g. the article about pigs is called "Pig" rather than "Pigs", even though it talks about all the billion pigs in the world and all the umpteen breeds of pigs. That rule is useful for readers and editors alike, since it helps them guess the right name of the article. So this article should preferably be renamed "Color of noise" or "Noise color", without changing its contents. --Jorge Stolfi (talk) 02:36, 13 March 2013 (UTC)

Third-octave noise
The colours of third-octave noises are missing in this article. These are frequently used for audio analysis. See also: Third-Octave Filter Banks --Bautsch (talk) 12:46, 30 October 2013 (UTC)

 * What colors? Dark? Warm? Brilliant? Binksternet (talk) 14:29, 30 October 2013 (UTC)

Integrating 3 dB/oct spectrum
"Pink noise is the only power-law spectral density that has this property: all steeper power-law spectra are finite if integrated to the high-frequency end, and all flatter power-law spectra are finite if integrated to the DC, low-frequency limit."

Wouldn't this apply to blue noise, too? — Preceding unsigned comment added by 96.224.69.35 (talk) 15:00, 22 May 2014 (UTC)

No, in that case the integral is clearly diverging. pink noises is the integral of 1/f df, which is log, which is -inf at zero and inf at inf. blue noise is int f df, which is f^2, inf at inf and zero at zero. — Preceding unsigned comment added by 100.45.64.131 (talk) 04:44, 17 July 2014 (UTC)

Green noise as bounded Brownian noise
What kind of bounds are meant to be applied? Most likely the process should be bounded in the space or amplitude domain (i.e., the position of the particle undergoing Brownian motion is constrained within some "container"), but another definition of green noise mentions bounding of white noise in the frequency domain, so I want to make sure.

I noticed that this is the only green-noise definition that currently lacks a citation. A previous discussion on this talk page mentioned http://www.dxarts.washington.edu/courses/565/clm-2/green.cl, but that looks like a dead link (returns HTTP 200 after redirecting to the domain without www, but "There are no courses listed on our site that meet your filtering criteria."). --SoledadKabocha (talk) 20:42, 13 September 2015 (UTC) (+proofread by self 04:50, 19 October 2015 (UTC))

Examples of noises
It should give examples of noises by color that people commonly hear in everyday life. Planet Star  19:16, 6 October 2017 (UTC)

 * If I understand ANY of the article, you need to beware confusing "noise" with "sound". What people commonly hear is "sound" as explained briefly in the article. Wordwood (talk) 12:07, 26 September 2022 (UTC)

Definition of "Power"
The introductory paragraph gives an overview with mentions of "power" and "power spectrum", with those terms linking to their corresponding Wikipedia entries. However, these entries are generic explanations of these terms as used in physics and engineering, and not helpful in understanding how they are applied to sound, and specifically to noise color. Each subsequent technical definition for specific colors of noise refer to the power for each frequency band but it is still a mystery to the layman, even a reasonably well-informed layman, exactly what is meant by "power" here. A layman's explanation of this term specific to the topic of noise color would be much appreciated. — Preceding unsigned comment added by 6StringJazzer (talk • contribs) 15:24, 2 December 2018 (UTC)

Vacuum energy
Quantum fluctuations of the electromagnetic field in the vacuum are blue noise, are they not? (3D blue noise power being proportional to f^3, just like 3D pink noise is proportional to f^-3). This should be added. 97.116.77.170 (talk) 19:38, 11 August 2019 (UTC)

Graphs might need an explanation
For example, the description of white noise makes you expect either a graph in logarithmic frequency space that slopes up as the frequency increases, or a graph in linear frequency space that stays flat. Currently it has a graph in logarithmic frequency space where the power stays flat, which seems wrong, but many commercial music production spectrometers graph white noise similarly, so it can't be completely wrong.

I wonder if the difference between these methods is measuring the power of single frequencies along the spectrum which leads to a flat graph regardless of the type of frequency space, versus measuring the average power of ranges of frequencies that correspond to equal width sections in the graph, which would lead to a sloped graph in logarithmic space. :shrug: 80.220.73.154 (talk) 00:52, 29 January 2020 (UTC)

Red vs. Brown vs. Brownian
To my understanding Brownian noise is not the same as red or brown noise: Brownian noise has memory, like the random walk of moving molecules, and is normal-distributed. While red and brown noise don't have memory, - they are the result of filtered equal distributed white noise. The confusion might happen because for experiments mostly the spectral density is the only importance, together with the similar naming. 93.237.16.85 (talk) 23:43, 11 April 2022 (UTC)

Orange Noise?

Congratulations!
Congratulations! It's my pleasure to let you know that, consensus being reached, you are now an administrator. You should read the relevant policies and other pages linked to from the administrators' reading list before carrying out tasks like deletion, protection, banning users, and editing protected pages such as the Main Page. Most of what you do is easily reversible by other sysops, apart from page history merges and image deletion, so please be especially careful with those. You might find the new administrators' how-to guide helpful. Cheers! -- Cecropia | explains it all ® 17:24, 6 Jun 2005 (UTC)

 * Good job, congrats, and my support was only there because I think you'll make an excellent administrator. --Scimitar 22:55, 7 Jun 2005 (UTC)
 * Congratulations as well... It's great working with you, I know you'll make a great admin.  Thanks also for supporting my RfA, much appreciated.  JYolkowski // talk 23:19, 7 Jun 2005 (UTC)
 * Congrats from me too - you'll be a good admin. Grutness...  wha?  23:44, 7 Jun 2005 (UTC)

"Le" & "le"
First, congrats on your election as administrator, I'm sure you will do a great job.

Second, I don't think we should get too hung up on the capitalisation of "le" and "la" and just use redirect pages where feasible. There is so much variability, and individuals have been known to use different versions of their own name. For example, "Leblanc" can also be rendered leBlanc, LeBlanc, le Blanc and Le Blanc (not to speak of the French from France Leblond, as French French has lost the distinction between "on" and "an" which Canadian French still retains). While I agree the DoCB is authoritative, I believe we need to keep the ultimate user in mind who might also use different capitalisations.

Third point is about the use of curly apostrophes (smart quotes in Microsoft-speak). I do share what you called "typography weeniesm", and use them all the time when I am writing stuff. However, they can cause havoc with different computer systems and browsers (You saw my botched attempt to redirect de Salaberry's son — Thank you for fixing it). I think it would be better to use plain vanilla ASCII straight "'" in article titles or use the HTML code "rsquo" (with the "&" and ";", of course). See Help:Special characters section on "Typeset-style Punctuation". Luigizanasi 20:33, 6 Jun 2005 (UTC)

Adminship
Congrats again on becoming a sysop. Thanks for offering to nominate me. As for my edit count, I seem to meet most voters standards for adminship. If you feel I would make a good admin, you probably do not have to wait for the nomination. I am quite sure that I wouldn't pass with as big of a margin as you, but I probably would stand a good chance of being promoted. And if I am not promoted, what's the harm? -- JamesTeterenko 03:00, 8 Jun 2005 (UTC)

 * If you want to wait to nominate me, that is fine. I do actually spend a fair amount of time on VfD when I can, particularly those noted on the Canadian wikipedians' notice board.  I don't bother voting on items where consensus has been reached or if I don't have a strong opinion on deleting.  So many of the VfD candidates are situations where they do little harm if kept but also add so little value that deleting does virtually no harm.  Putting a vote of abstain adds no value to the other voters, so I don't bother.  I also find it funny that anything I tag for speedy deletion is removed from my edit history.  Being an admin on other wikis, I do understand its value and risk.  However, I am not going to artificially inflate my edits to get this ability here.  -- JamesTeterenko 20:02, 8 Jun 2005 (UTC)

User:Humanbot update 08 June 2005
Version two-two released today includes in that green box a nice count of how many articles are left. This more or less co-incides with the event of hitting only 1000 articles remaining. Also, I have re-arranged the User:Humanbot page to make it easier to get to the right stuff. Progress charts, wikicookies, wikilove and a more thorough spelling check is promised when this is completed.

British spelling
Just to point out that the correct British spelling of "honorific" is "honorific" (your edit. In some compounds like this, inserting the 'u' is a permissible variant, but here, according to the OED, it's unambiguously wrong.

Perhaps we should mention this in the style guide to discourage the hordes of overcourteous Americans (or nationalistic Brits who can't spell) changing such perfectly correct words as "honorific", "humorist", etc.? A priori it seems unreasonable to expect people to be able to spell reliably in versions of English other than their own. —Blotwell 04:55, 9 Jun 2005 (UTC)

No worries!
Was happy to support your RfA and glad to see it was successful. Hope you are enjoying the new tools, rollback is exceptionally useful. Thanks for your vote, too, on my RfA a few weeks back, it was much appreciated. Thanks also for your edit to my page, adding Lord Dufferin to my list - your wording for the title encompassed him nicely!

Categories
Hello. What about categories: Mountains of South Korea and Mountains of North Korea? I think it should be deleted, cause of existing category:Mountains of Korea. I think that it's better to leave it here and do not make subcats, cause of terrain of Korean Peninsula. Practically every Korean mountain would be in both categories. What do you think? -- Darwinek 18:44, 10 Jun 2005 (UTC)
 * Well, if it was mountain RANGES of Korea, then there might be an argument for this. But really if it is mountain peaks they should be in separate cats under Mountains by nationality or whatever it is, and ditch the Mountains of Korea cat. Fawcett5 18:46, 10 Jun 2005 (UTC)

User:Humanbot update 13 June 2005
The spelling2 project (to work on secondary namespaces) was opened and finished. Progress charts will be available soon.

Version six-three tracks who made the edits, and rankings are available. Much of the work was done while I was asleep, explaining my low place ;).

The next project, which may even be released today, will probably fix incorrectly capitalised headings, particularly "See Also" and "External Links".

The mailing list has grown to 24 people and while that is very nice for my ego, it is rather difficult to send out updates. This is why I did not send out a notice that the spelling2 project had opened. From now on, then, you must watch User:Humanbot/announce for updates. r3m0t talk 12:03, Jun 13, 2005 (UTC)

Ridings and Constituencies
Re: Minnedosa

It's my understanding (now) that the term "riding" is only officially used at the federal level, while the term "constituency" is used provincially. Most people use the terms interchangeably, but there is a technical distinction -- for this reason, I've decided to make the changes where appropriate. CJCurrie 17:39, 17 Jun 2005 (UTC)
 * Ontario, at least, calls them ridings . My understanding is that the term is just one of our quaint Canadianisms, and is indeed fully interchangeable. Fawcett5 20:16, 17 Jun 2005 (UTC)

 * Falphin, the licence that the anon user refers to is entirely unsuitable for use on wikipedia, since it says that it must be a true reproduction of the original.

Very belated thank you
Thanks for your comments, and especially for the assistance on Wikipedia articles. I actually wanted to thank you for the newcomer award you gave me; I thought I already had and just now realized I hadn't. It made me smile while one user was using sockpuppets and generally being difficult. It's occasionally good to be reminded that the majority of Wikipedians are like yourself- friendly, well-intentioned, and community-oriented. Thanks. --Scimitar 22:27, 21 Jun 2005 (UTC)

MP lists
Just noticed that you typed up the alphabetical lists of MPs over the years...great job! I'm filing them in the Members of the Canadian House of Commons category now. The only suggestion I've got right now is to check the lists against the appropriate categories, because I've already found two redlinks where we already have an article under a different form of the person's name. No biggie, though -- either creating redirects or editing the linked names in the list will take care of that. Bearcat 01:28, 25 Jun 2005 (UTC)

 * Bearcat, thanks, I knew it wouldn't take you long to notice the new lists. They were generated based on names from a database dump from the Library of Parliament website, and I could only get it into wikipedia format by using peoples formal full names... So yes, there will be a lot of redlinks that should be blue, and also a lot of blue links that are currently pointing to the wrong person and will need to be disambiguated.  I'll need all the help I can get checking though, there are nearly 3,500 names on the lists!.  Cheers, Fawcett5 03:31, 25 Jun 2005 (UTC)

There are 166 other Canadian companies so categorized. Why not HBC? Am I missing something? -- Mwanner June 29, 2005 23:14 (UTC)

Template:Elec
The Manual of Style (links) says:

 * Try to link accurately. While editing you can use preview to check a link, and follow it by opening the page in another window. If an article you want to link doesn't yet exist, do a quick search to find out if that is really the case; the article may have a different name than you expect. A link going straight to the target is preferred over a link relying on a redirect.

So please don't change "Canadian federal election, YYYY" to "YYYY Canadian election". The latter links to a redirect, and not to the article. Thanks. Ground Zero 5 July 2005 20:49 (UTC)
 * Ground Zero, please keep your hands off my private template. As the content there is not stable, I probably won't even notice if you edit it, and the content there is subject to being reverted to a way earlier version at my whim. If you don't like the way that things are linked in the articles created from the template, then fine, fix them. Be aware that the link style in the template long predates the current format used for the names of Canadian elections. Also, redirects are cheap, so don't get bent in a knot. Fawcett5 5 July 2005 20:53 (UTC)

I wasn't aware that it was your "private template" since it is not a branch from your user page. I encourage you, as does the Wikipedia Manual of Style to link correctly. I did not set that policy, I am only making you aware of it. I think it is there for a good reason. I am not clear what advantage is gained from linking incorrectly. Linking correctly, too, is cheap. :"so don't get bent in a knot" Ummm.... why are you being so hostile? Can I suggest that you review Civility? Like you, I am just here to contribute to building an encyclopedia. Personal attacks are not necessary. Ground Zero 5 July 2005 21:16 (UTC)

Brasseur de Bourbourg
Hi there, Fawcett5. Firstly, thanks for verifying that I had correctly linked Charles Etienne Brasseur de Bourbourg with the right entry in the CDB. However, I plan to restore the reference to the Maya Hieroglyph handbook source in this latter article, since it contained some of the biog data for him which I had used to earlier update the entry. This source (and some others which I have not yet annotated) recounts his involvement in the general history of Mayan decipherment, and contains data which is not available in his Canadian Bio entry, which focuses naturally enough on his association with Quebec. In fact, most of my updates so far to this article have been based on sources other than his Canadian Biog db entry, which I had not been aware of until I came across the link to it a short while ago when doing a general search for other mentions of him in Wikipedia. The Canadian Biog. entry does contain some good data, and I plan to incorporate more of that info in future updates. Cheers. --cjllw | TALK  04:27, 2005 July 21 (UTC)

NPOV question
Hello.

I was wondering if you could help me with a problem. Many people have been trying to expand the article for Old Dominion University. However, any changes made to the article are immediately deleted by a user called Agriculture. The article's history suggests that he is very determined to disparage this university's reputation. I don't want to cause any trouble, but is there anything that can be done about this?

I would appreciate any advice or help you have to offer. Thank you in advance.
 * I would appreciate help in this matter as well. Many times have I posted to the talk page of Old Dominion University with the reasons why false acclaim for ODU is baseless.  I have no intention to "disparage" the reputation of the university, but having come from that area after many many years of life there, and a close connection to Universities in general, I feel honor bound to make sure the article is factual.  All information in the article is a factual account, NPOV, and not in the least disparaging.  I have reverted recent destructive edits, yes.  Why?  Because those who have made them have failed to address the consensus reached on the talk page after the evidence was presented.  If there are individuals who wish to make a case for their point, then they should feel free to do so on the talk pages.  But until that time comes, their continued vandalism of the page to promote the university unfairly is, I feel, against Wikipedia policy. Agriculture 07:16, 21 July 2005 (UTC)

 * I'm a bit hesistant to wade back into this, but the truth probably lies somewhere in the middle. For the time being I will refrain from editing the article myself and will suggest a compromise:
 * Agriculture is in general right, there is a lot of biased boosterism in university articles, and we must guard against this. He has also established that several of ODUs programmes are nowhere near "acclaimed". For instance, they train a lot of engineers, but not particularly well regarded ones.  Most of that "acclamation" language was stripped out of the article a long time ago though, and it looks as though the current dispute boils down to one paragraph.
 * ODU does have pretty low academic standards. So it is fair to point this out, but should be done dispassionately. Agriculture, perhaps you should clarify right in the article that the tier 4 designation is from US News and world reports.  I suggest saying it is a ODU is a tier 4 university by the US News criteria and leave it at that — that alone makes things pretty clear.  I have no problem in principal with the USN&WR tier being reported in every US university article.
 * The Carnegie classification should be kept. This is incredibly widely used within academia (currently) as a method for describing institutional behaviour and classifying institutions. It should be included in every US university article. Note that it says NOTHING about institutional rankings, only really the scope of the universities activities — i.e. what flavour of school it is. ODU does offer PhD's in a a wide variety of fields, thus the research-extensive designation. Normally this designation is only achieved by fairly large schools with many programmes. It will be interesting to see what happens to ODU though when Carnegie updates their criteria this year.... The Carnegie classification system is also definitely worthy of its own article, which would go a long to clear up any mistaken notion that this is a ranking, rather than a classification..
 * The claim that the reason for ODU's failure to improve is due to the local crime must be substantiated with a reference to be keptl, otherwise it is just opinion.
 * As for attracting good students and faculty, that's a bit of a "chicken and the egg" business, isn't it? To my mind, it is perhaps the essentual determinant of a good school..Good schools do, bad schools don't....maybe someone can find an article about ODU's attempts to recruit better faculty or increase its admission standards?
 * In no way can the modern ODU be fairly characterized as a "community college". Commuter college does probably has more truth to it — maybe there is a statistic about the percentage of undergrads who live on-campus that would indicate if this is a fair characterisation?
 * Finally, I must caution Agriculture about his calling the placement of the NPOV tag on the article vandalism. It does seem there is a real dispute for the moment about the article's neutrality, and such tags should be left alone until some accomodation is reached. In general one must be very careful about allegations of vandalism in the context of a content dispute. Also my reading of the discussion page doesn't seem to indicate that a consensus was ever reached.

Cheers, Fawcett5 13:06, 21 July 2005 (UTC)

 * I'll endeavor to make the edits you indicate. As far as calling the NPOV tag vandalism, here is my reasoning:  This tag was added without editing the discussion page to add new information.  This matter has not been brought up for months and now a single user comes back and slaps it on the article WITHOUT editing the discussion page to indicate why.  This, as far as I can divine from Wikipedia policy pages, does constitute vandalism as it is an inappropriate use of the tag.  Otherwise perhaps it would be fine for myself or someone else to log on fron anonymous accounts and place this tag on other pages without backing up our position?  I am of the opinion that unless the party concerned with NPOV takes enough interest in the NPOV issue to detail it himself on the talk page, that the tag constitutes vandalism.  I believe Wikipedia agrees with me.
 * As far as consensus goes, I have in the past done great research on this issue to back up the article. Whenever I have responded to NPOV accusations on the subject the result is the same, I post a lengthy result from such research and all the concerned parties evaporate abandoning the issue.  If they don't care enough to respond with their own points or to argue the point further, in my mind at least, the matter has reached consensus. Agriculture 14:12, 21 July 2005 (UTC)

Adminship?
Hi Fawcett5,

No problem with the Canadian senators category work. This was long overdue and I am happy to help. As for the admin, I am content at being one of the "grunts" for now and staying out of the spotlight. All the best, --YUL89YYZ 17:56, July 25, 2005 (UTC)

your revert
Any particular reason you decided to rv my addition of a stub cat to Illinois Central Gulf Railroad? Tomer TALK 19:44, July 25, 2005 (UTC)
 * Yes, the stub as you had it was broken and did not correspond to any actual template, making the edit indistinguishable from vandalism. Please review your edits to make sure that you've gotten things right. I haven't seen Wisconsin stub before, but perhaps you meant Wisconsin-stub (with a hyphen)? In any case, I strongly discourage you from adding innapropriately geographically restricted stubs to something like an interstate railway. The article is already appropriately stubbed. Fawcett5 20:09, 25 July 2005 (UTC)
 * I'm not going to argue with you or fight about it, but the fact of the matter is that some editors look for articles based upon their stub cat, in order to improve them. What you have done, effectively, is to ensure that only railroad buffs will see that the article is in need of expansion.  If that's your hope, then more power to you, but my POV is that you've disserviced the article by removing a potential interest group from considering the article "in need of expansion".  That said, there is nothing about Wisconsin-stub that is remotely interpretable as "geographically restricted".  In that light, since that's the only rational excuse you've given (a misspelled stub should have been corrected, not removed), I will continue to regard your removal as inappropriate.  Tomer TALK  05:52, July 26, 2005 (UTC)
 * I'd be more open to "cool[ing] it" were it not obvious that you knew by the time you responded to my inquiry that the "problem" was that I had neglected to hyphenate the stub tag. That was clearly not, at least from your response to my inquiry above, your core rationale for removing the stub tag.  Tomer TALK  05:55, July 26, 2005 (UTC)
 * Anyways, I don't want to fight about it. Pax?  Tomer TALK  06:34, July 26, 2005 (UTC)

Well, by means of clarification, I was bumbling through every single article within Wisconsin-related categories looking for stubs, and adding Wisconsin-stub to all the stubs in such cats, including the one that popped up on your watchlist. I went through about 1500 articles in about 3 hours, and moved a LOT of stubs to the bottom of articles (which is where I feel they belong, i.e., below any other templates etc.) and the article that you happened to revert was one of but about 20 RR-related stubs that seemed to be a source of conflict, and then only because I'd added the Wisconsin-stub to it. Understand--Wisconsin-stub is not a "restrictive geo stub" as you've characterized it--it is a stub cat that encompasses any article that can be related to Wisconsin in any way, including if a part of a certain railway's lines traverse the state. Nothing about the stub tag is meant to characterize articles in which it appears as exclusively "Wisconsin" domain, rather it is meant as a way to alert editors with Wisconsin-related expertise as to which Wisconsin-related articles are in need of attention or expansion. For what I hope is now a more understandable rationale, I still maintain that your removal of the tag is a detriment to the article, but as I said, I'm not going to fight with you, at least not on the article level, about it. Kindest regards. -Tomer TALK 08:36, July 27, 2005 (UTC)

 * I'm going to throw my support behind User:Fawcett5 here. 13 categories is downright ridiculous.  User:Fawcett5's categorization is much more appropriate. The point isn't to exhaustively categorize in every possible way but to make articles useful for readers.  13 categories is not useful, it obscures it. Agriculture 07:17, 26 July 2005 (UTC)

Topic of Concern
It might be worthwhile to keep an eye on a newly forming group. They could be legit, but I am a bit worried this is an attempt to insert POV into articles through amassing a group of like minded editors, ensuring editwars and the like are won. I am most concerned by the inclusion of a certain member, given his POV track record and some of his recent handiwork. I'm not suggesting any action other than monitoring, but thought it might be a good idea. Agriculture 05:58, 27 July 2005 (UTC)

Pierre Desproges

Pierre Desproges (9 May 1939 – 18 April 1988) was a French humorist. He was born in Pantin, Seine-Saint-Denis. According to himself, he made no significant achievements before the age of 30. From 1967 to 1970, he worked as: life insurance salesman, opinion pool investigator, "lonely hearts" columnist, horse racing forecaster, and sales manager for a styrofoam beam company.

From 1970 to 1976, he worked for the newspaper L'Aurore. Starting in 1975, he became a "reporter" on Le petit rapporteur (The Little Snitch), a satirical TV show hosted by Jacques Martin. He caught the public's attention with unconventional interviews of celebrities, among them novelists Françoise Sagan or Jean-Edern Hallier.

He appeared for the first time on stage at the Olympia theater during a Thierry Le Luron show. Among other things, he became very famous for his Chroniques de la haine ordinaire (Chronicles of Ordinary Hatred), a 1986 radio show.

In the 1980s, he appeared daily on Le tribunal des flagrants délires (a pun on the French term "flagrant délit" meaning red-handed), a comedy show where celebrities were judged in mock-trials. Desproges held the part of the prosecutor for more than two years, a part for which his verve, his scathing humour and his literary erudition were ideally suited.

In 1982, he created La minute nécessaire de Monsieur Cyclopède, a series of shorts for TV, where he played an omniscient professor. He answered to metaphysical and nonsensical questions such as "How to make King Louis XVI fireproof?", proved that Beethoven was not deaf but stupid, and explained why the improbable encounter between the Venus de Milo and Saint Exupéry's 'Petit Prince' was a fiasco. Each episode ended with the catchphrase: "Étonnant, non ?" ("Astonishing, isn't it?")

In 1984, he had his first stand-up show at the Théâtre Fontaine. In 1986, his second stand-up, Pierre Desproges se donne en spectacle was presented at the Théâtre Grévin. He started work on a third stand-up, and the drafts were ultimately published in 2010.

In 1987, doctors discovered he had inoperable lung cancer in an advanced stage, and his relatives, in agreement with the doctors, decided to hide the condition from him, so he could spend his final days quietly. He died in 1988, from a disease he had bitterly laughed at time and time again, often saying "I won't have cancer: I'm against it". He is buried in the Père Lachaise Cemetery in Paris. His family publicly announced his death with the sentence (which he had prepared): "Pierre Desproges est mort d'un cancer, étonnant, non ?" ("Pierre Desproges died of cancer, astonishing, isn't it?")

"We can laugh about everything, but not with everyone"
Pierre Desproges is the author of many memorable quotes, in particular "you can laugh about everything, but not with everyone". Although Pierre Desproges never actually wrote it in his texts, he did confirm that "I do think that we can laugh at everything, but not necessarily with everyone.".

The quote comes initially from an "indictment" that Desproges pronounced as "Prosecutor of the French Republic" against far-right Jean-Marie Le Pen on 28 September 1982 at Tribunal des flagrants délires on France Inter radio. In the first part of his speech, Desproges declares: "Two questions haunt me. First, can we laugh at everything? Secondly, can we laugh with anyone?". His answer to the first question is "yes, undoubtly". He adds that not only we "can" laugh at everything but that we "must" laugh at everything to "desacralize our stupidity, exorcise our true sorrows and beat our mortal anxieties". To the second question, he answers "it's difficult", in the sense that he, Pierre Desproges, does not want to laugh with anyone, especially the guest of that day, Jean-Marie Le Pen. Pierre Desproges later adds that laughing with "a practicing Stalinist", a "hysterical terrorist" or "far-right activist" is beyond his abilities.

The French magazine Télérama published an interview of Pierre Desproges on 24 November 1982, two months after the broadcast, where Pierre Desproges explains: "I think we have the right to laugh at everything. But to laugh with anyone, maybe not. (...) Laughter is an outlet and I do not understand why we should not laugh at what hurts. Things hurt less when we laugh".

Desproges reformulates his ideas the following year, in November 1983, in his book Vivons heureux en attendant la mort (Let us live happy while we wait to die): "It's better to laugh at Auschwitz with a Jew than to play Scrabble with Klaus Barbie". Bernard Pivot invites Pierre Desproges to Apostrophes, a French TV literary talk show on 30 December 1983, to promote his book. Pierre Desproges says "we can laugh at absolutely everything but not with anyone", and declares that when he prepared the speech about Jean-Marie Le Pen, he "did not want to laugh with him".

European School, Mol

The European School, Mol was the third of the thirteen European Schools to be established, and is one of five such schools in Belgium. Founded in 1960, it is located in Mol, in the province of Antwerp.

The school was primarily established to provide an education to the children of staff posted to nearby domestic, and European atomic research projects and facilities; the Belgian governments' nuclear research centre, the Organisation for Economic Co-operation and Development's Eurochemic nuclear fuel reprocessing plant (now defunct), and the European Atomic Energy Community's Central Bureau for Nuclear Measurements (now under the auspices of the European Commission as the Institute for Reference Materials and Measurements).

However, the school has also welcomed children from other European or overseas families who live and work in the area. Buses bring pupils from as far as Antwerp and Eindhoven, with nearby facilities to accommodate boarders during the school week.

Johns Hopkins School of Medicine

The Johns Hopkins University School of Medicine (JHUSOM) is the medical school of Johns Hopkins University, a private research university in Baltimore, Maryland. Founded in 1893, the School of Medicine shares a campus with Johns Hopkins Hospital and Johns Hopkins Children's Center, established in 1889.

Johns Hopkins School of Medicine consistently ranks among the top medical schools in the United States in terms of research grants awarded by the National Institutes of Health, and other factors.

History
Before his death in 1873, Baltimore financier and philanthropist Johns Hopkins appointed a 12-member board of trustees to carry out his vision for a university and hospital that would be linked to each other by a medical school, which was at the time a radical idea.

The Johns Hopkins University was established first, opening in 1876. Construction of the Johns Hopkins Hospital began in 1877 with the razing of the site formerly occupied by the city's mental asylum, and took twelve years to complete. By the time the Hospital opened in 1889, only six of the original twelve trustees appointed by Hopkins were still alive. Despite having already recruited the necessary faculty, the board no longer had enough funds to establish the medical school.

Four the original trustee's daughters, led by Mary Elizabeth Garrett, stepped in to spearhead a nationwide fundraising campaign to secure funding for the medical school, on the condition that the remaining trustees agree to open the medical school to both men and women, who were generally excluded from medical education in the 1890s. When the Johns Hopkins University School of Medicine finally opened its doors in 1893, there were three women in its first class.

The founding physicians of Johns Hopkins School of Medicine, sometimes referred to as the "Big Four", were pathologist William Henry Welch (1850–1934), the first dean of the school and a mentor to generations of research scientists, Canadian internist William Osler (1849–1919), who was perhaps the most influential physician of the late 19th and early 20th centuries and the author of The Principles and Practice of Medicine (1892), surgeon William Stewart Halsted (1852–1922), who revolutionized surgery by insisting on subtle skill and technique and strict adherence to aseptic technique, and gynecological surgeon Howard Atwood Kelly (1858–1943), credited with establishing gynecology as a specialty and being among the first to use radium in the treatment of cancer.

Facilities
The School of Medicine, along with the Johns Hopkins Hospital (the School of Medicine's primary teaching hospital), Johns Hopkins Children's Center, Bloomberg School of Public Health, and School of Nursing, are located on the Johns Hopkins Medical Campus in East Baltimore.

The wider Johns Hopkins Medicine system includes several other regional medical centers, including Johns Hopkins Bayview Medical Center on Eastern Avenue in East Baltimore, Howard County General Hospital near Ellicott City, Suburban Hospital in Bethesda, Sibley Memorial Hospital in Washington, D.C., and Johns Hopkins All Children's Hospital in St. Petersburg, Florida. Together, they form an academic health science center.

Reputation and rankings
According to the Flexner Report, Hopkins has served as the model for American medical education.

Its major teaching hospital, the Johns Hopkins Hospital, was ranked the top hospital in the United States every year from 1991 to 2011 by U.S. News & World Report. In 2024, U.S. News & World Report ranked Hopkins #2 medical school in the U.S. for Research, and #92 for Primary Care. U.S. News also ranked Hopkins #1 in Anesthesiology, #1 in Internal Medicine, #2 in Obstetrics and Gynecology, #4 in Pediatrics, #3 in Psychiatry, tied at #3 in Radiology, and #1 in Surgery.

Colleges Advisory Program
Upon matriculation, medical students at Johns Hopkins School of Medicine are divided into four colleges named after famous Hopkins faculty members who have had an impact in the history of medicine, Florence Sabin, Vivien Thomas, Daniel Nathans, and Helen Taussig. The colleges were established to "foster camaraderie, networking, advising, mentoring, professionalism, clinical skills, and scholarship" in 2005.

In each incoming class, 30 students are assigned to each college, and each college is further subdivided into six molecules of five students each. Each molecule is advised and taught by a faculty advisor, who instructs them in Clinical Foundations of Medicine, a core first-year course, and continues advising them throughout their 4 years of medical school. The family within each college of each molecule across the four years who belong to a given advisor is referred to as a macromolecule. Every year, the colleges compete in the "College Olympics" in late October, a competition that includes athletic events and sports, as well as art battles and dance-offs.

Governance
The Johns Hopkins University School of Medicine is led by Ronald J. Daniels, president of Johns Hopkins University, and Theodore DeWeese, dean of the medical faculty and chief executive officer of Johns Hopkins Medicine. Kevin Sowers serves as president of Johns Hopkins Health System and executive vice president of Johns Hopkins Medicine.

Nobel laureates
As of 2024, 29 Nobel laureates have been affiliated with Johns Hopkins University as faculty, fellows, residents, or graduates, with 15 out of the 29 being associated with the School of Medicine specifically, including 14 out of the university's 17 laureates for the Nobel Prize in Physiology or Medicine and 1 out of the university's 3 laureates for the Nobel Prize in Chemistry. Two laureates, Peter Agre and Gregg Semenza, are current faculty at the School of Medicine.

The 1985 Nobel Peace Prize was awarded to International Physicians for the Prevention of Nuclear War (IPPNW). Two of the six founding members of the organization, Bernard Lown (M.D. 1945) and James E. Muller (M.D. 1969) were graduates of the Johns Hopkins School of Medicine.
