Excerpts

 * Wikipedia is not merely an online multilingual encyclopedia; although the Web site is useful, popular, and permits nearly anyone to contribute, the site is only the most visible artifact of an active community. Unlike previous reference works that stand on library shelves distanced from the institutions, people, and discussions from which they arose, Wikipedia is both a community and an encyclopedia. And the encyclopedia, at any moment in time, is simply a snapshot of the community's continuing conversation. This conversation frequently exasperating, often humorous, and occasionally profound. Most importantly, it sometimes reveals what I call a good faith collaborative culture. Wikipedia is a realization -- even if flawed -- of the historic pursuit of a universal encyclopedia: a technology-inspired vision seeking to wed increased access to information with greater human accord. (p. 1)
 * ... Wikipedia culture encourages contributors to treat and think of others as well. For example, participants are supposed to abide by the norm of "Wikiquette," which includes the guidelines of "Assume Good Faith" (AGF) and "Please Do not Bite the Newcomers."6 Such Wikipedia norms and their relationship to the technology, discourse, and vision of a universal encyclopedia prompt me to ask: How should we understand this community's collaborative -- "Good faith" -- culture? In the following chapters I offer my understanding on this question, but, first, an introduction. (p. 3)
 * When I speak of Wikipedia I am referring to a wiki project, which includes both the textual artifact and the community producing it. (This is a common usage, as is referring to Web sites without a definite article, that is "I searched Google and Wikipedia" not "I searched the Google and the Wikipedia.") Furthermore, there is a particular vision of access and openness at Wikipedia, as seen in its slogan as "the free encyclopedia that anyone can edit." This vision, the encyclopedia, and its community and culture are introduced in the sections that follow. (p. 3)
 * The Wikimedia Foundation, the nonprofit organization under which Wikipedia and its related projects operates, asks the reader to "Imagine a world in which every single human being can freely share in the sum of all knowledge. That's our commitment."7 However, this commitment is not unique to the new millennium. Indeed, Wikipedia's heritage can be traced back to Paul Otlet's Universal Repertory and H. G. Wells's proposal for World Brain (included in a 1937 book of the same title). These projects were conceived as furthering increased access to information: facilitated by the (then relatively novel) technologies of the index card, loose-leaf binder, and microfilm. However, this vision exceeds the production of information. Wells proposed that reference work compilers would be joined by world scholars and international technocrats to produce a resource that every student might easily access, in a personal, inexpensive, and portable format. Furthermore, this collection of the world's intellect was envisioned to yield a greater sense of unity: Wells hoped that such an encyclopedia could solve the "jig-saw puzzle" of global problems by bringing all the "mental wealth of our world into something like a common understanding"; this would be more than an educational resource, it would be an institution of global mediation.8 Wikipedia shares this concern for "the sum of all knowledge" with early visionaries. And while no one argues that Wikipedia will bring about world peace, I do argue goodwill is necessary to its production and an occasional consequence of participation. (pp. 3-4)
 * However, while most early Wikipedians were probably unaware of these predecessors from a century ago there was a more immediate inspiration: Free and Open Source Software (FOSS). One of the earliest news articles about Nupedia, Wikipedia's non-wiki progenitor, notes: "The philosophy of the open-source movement is spreading within the industry. Now, a maker of a Web-based encyclopedia wants to apply its principles to share knowledge in general."9 Nupedia described itself as "the open content encyclopedia" and was available under the GNU Free Documentation License. (GNU is a seminal free software project.) FOSS is licensed to enable users to read and improve on the source of the software they use. This has proven to be a much noted alternative to proprietary software in which one's usage can be restricted (e.g., unable to backup, install multiple couples, repair, or improve). When I emailed Jimmy Wales to ask about the influence of FOSS on his thinking, he replied: 	In general what I can say is that Nupedia was absolutely inspired by the free software movement. I spent a lot of time thinking about online communities and collaboration, and one of the things that I noticed is that in the humanities, a lot of people were collaborating in _discussions_, while in programming, something different was going on. People weren't just talking about programming, they were working together to build things of value.10 Consequently, the inspiration for a free and open source encyclopedia -- in terms of access, cost, and collaboration -- might be thought of as the most recent state of a long-running pursuit. (p. 4)
 * Wikipedia is the wiki-based successor to Nupedia and its name is a portmanteur of "wiki," an online collaborative editing tool, and "encyclopedia," itself a contraction of the Greek enkyklios and paidei, referring to the "circle of learning" of the classical liberal arts. This name is evidence of a geeky sort of linguistic humor and also prompts the question of whether a relatively open-to-all wiki can also be a high-quality reference work. In the following pages I return to these points but for now let's consider the wiki and encyclopedic aspects of the thing we call Wikipedia. (pp. 4-5)
 * Wikipedia is an online wiki-based encyclopedia. "Wiki wiki" means "super fast" in the Hawaiian language, and Ward Cunningham chose the name for his collaborative WikiWikiWeb software in 1995 to indicate the ease with which one could edit pages. (He learned of the word during his first visit to Hawaii when he was initially confused by the direction to take the "Wiki Wiki Bus," the Honolulu airport shuttle.11) In a sense, the term wiki captures the original conception of the World Wide Web as both a browsing and editing medium; the latter capability was largely forgotten when the Web began its precipitous growth and the most popular clients did not provide their users with the ability to edit Web pages. (p. 5)
 * The wiki changed this asymmetry by placing the editing functionality on the server. consequently, if a page can be read, it can be edited in any browser. With a wiki, the user enters a simplified markup into a form on a Web page. (p. 5)
 * The application of the wiki platform with a few encyclopedic features enables surprisingly sophisticated content creation.15 And, as we will see throughout this book, wikis often are thought of as potent collaborative tools because they permit asynchronous, incremental, and transparent contributions from many individuals. Yet, as is often the case, the consequence of this quick and informal approach of editing the Web was not foreseen -- or, rather, was pleasantly surprising. Wikipedia is the populist offshoot of Nupedia, started in March 2000 by Jimmy Wales and Larry Sanger. Nupedia's mission was to create a free encyclopedia via rigorous expert review under a free documentation license. Unfortunately, this process moved rather slowly and, having recently been introduced to wikis, Sanger persuaded Wales to set up a scratchpad for potential Nupeida content where anyone could contribute. However, there was "considerable resistance on the part of Nupedia's editors and reviewers to the idea of associating Nupedia with a wiki-style website. Sanger suggested giving the new project its own name, Wikipedia, and Wikipedia was soon launched on its own domain, wikipedia.com. on 15 January 2001."16 (p. 6)
 * I conclude with a reflection upon H. G. Wells's complaint of the puzzle of wasted knowledge and global discord. Seventy years later, Wikipedia's logo is that of a not yet complete global jigsaw puzzle. This coincidence is representative of a shared dream across the decades. The metaphor of the puzzle if useful in understanding Wikipedia collaboration: NPOV ensures that we can join the scattered pieces of what we think we know and good faith facilitates the actual practice of fitting them together. (p. 15)
 * Creating a world encyclopedia, much less world peace, is a difficult task and the trivia found on Wikipedia is a source of delight to some and derision to others. Nonetheless, the coupling of increased information access with human accord is along-held dream. While its advocates are sometimes overly exuberant they can also be pragmatic, as seen in Wales's 2004 "Letter from the Founder": Our mission is to give freely the sum of the world's knowledge to every single person on the planet in the language of their choice, under a free license, so that they can modify, adapt, reuse, or redistribute it, at will. And, by "every single person on the planet," I mean exactly that, so we have to remember that much of our target audience is not yet able to access the Internet reliably, if at all .... Our community already comes from a huge variety of backgrounds, and over time the variety will only increase. The only way we can coordinate our efforts in an efficient manner to achieve the goals we have set for ourselves, is to love our work and to love each other, even when we disagree. Mutual respect and a reasonable approach to disagreement are essential ... on this incredible ridiculous crazy fun project to change the world.    None of us is perfect in these matters; such is the human condition. But each of us can try each day, in our editing, in our mailing list posts, in our irc [Internet Relay] chats, and in our private emails, to reach for a higher standard than the Internet usually encourages, a standard of rational benevolence and love.3 (p. 18)
 * In Germany Wilhelm Ostwald (1853-1932) invested much of the award from his Nobel Prize for Chemistry in Die Brücke ("The Bridge"), an international institute he cofounded for organizing intellectual work across the world. Emanuel Goldberg (1881-1970), once a student of Ostwald's, advanced imaging technologies and developed a "Statistical Machine" by which microfilm records could be indexed and subsequently retrieved. (p. 20)
 * One can trace Wikipedia's heritage back to this period. as seen most clearly in the writings of two twentieth-century visionaries: Paul Otlet and H. G. Wells. (p. 20)

Differential equations/Separable differential equations

The order of a differential equation is the largest derivative involved. For example, in the equation $$\frac{d^2y}{dx^2} + \frac{dy}{dx} + y = 0$$, the largest derivative is the second, so the order is 2.

Separable Equations
One of the easiest class of ODEs to solve is separable equations.

Definition
A differential equation is called separable when it can be manipulated into an equation with the dependent variable and its differentials on one side of the equality, and the independent variable and its differentials on the other side. Thus, each side is in terms of a single variable.

Example
The equation $$\frac{dy}{dx} = y$$ has a fairly obvious solution if you know your differentiation rules well. Recall that $$\frac{d}{dx}e^x = e^x$$ and hence $$y=e^x$$ is a solution. But how could we have found this if we did not remember that $$e^x$$ happened to be its own derivative? Additionally, is it possible to find any more solutions? Observe that the equation above is separable, and can be written as $$\frac{1}{y}dy = dx$$. Now that both sides are in terms of their own variable, we can integrate:

$$\int\frac{1}{y}dy = \log{|y|} + C_1 = x +C_2 = \int dx$$

And thus, $$|y| = e^{x+C_2 - C_1} = e^x e^{C_2 - C_1} = Ae^x$$. Since $$C_1$$ and $$C_2$$ are arbitrary constants of integration, $$A = e^{C_2-C_1}$$ is another arbitrary constant, so that the final solution is $$y = Ae^x$$ for any $$A$$.

General Solution
Suppose we have some separable equation:

$$f(y)dy = g(x)dx$$

Then we can integrate both sides:

$$F(y) + C_1 = G(x) + C_2$$

Since the constants are arbitrary, we really only need one. However, do not forget the constant of integration, or you will lose a large number of solutions. Additionally, do not wait until the last step to add the constant of integration. Many times when learning calculus, students add a $$+C$$ to the end of a problem without really thinking, but remember that the $$C$$ comes from the integration, so you need to add it at that step. In the above example, adding the $$C$$ at the last step would give $$y = e^x + C$$ as a solution. But we can see that, for example, $$\frac{d}{dx}(e^x + 1) = e^x \neq e^x + 1$$, so that $$e^x + C$$ is not a solution (whenever $$C\neq 0$$)! At any rate, the equation is now of the form $$ F(y) = G(x) + C$$, which can be solved for $$y$$ using any available algebra tools.

In short:
 * 1) If possible, manipulate the equation using algebra to get each variable on its own side of the equation. The form should be $$f(y) dy = g(x) dx$$.
 * 2) Integrate both sides of the equation. Include a constant of integration.
 * 3) Solve for the function in terms of the independent variable.

It can be misleading, however, to think that a constant of integration necessarily must appear in the solution of a differential equation. This is true for linear equations, but for nonlinear ones, all bets are off.

Consider for example the equation

 * $$|y'| + |y| = 0$$.

The only solution to this equation is $$y = 0$$, and no arbitrary constant of integration can be imposed anywhere.

Differential equations/Exact differential equations

Definition
A differential equation of is said to be exact if it can be written in the form $$M(x,y) dx + N(x,y) dy = 0$$ where $$M$$ and $$N$$ have continuous partial derivatives such that $$\frac {\partial M}{\partial y} = \frac {\partial N}{\partial x}$$.

Solution
Solving the differential equation consists of the following steps:

 * 1) Create a function $$f(x,y) := \int M(x,y) dx$$. While integrating, add a constant function $$g(y)$$ that is a function of $$y$$. This is a term that becomes zero if function $$f(x,y)$$ is differentiated with respect to $$x$$.
 * 2) Differentiate the function $$f(x,y)$$ with respect to $$\frac {\partial f}{\partial y}$$. Set $$\frac {\partial f}{\partial y} = N(x,y)$$. Solve for the function $$g(y)$$.

Differential equations/Homogeneous differential equations

Definition
The word “homogeneous” can mean different things depending on what kind of differential equation you’re working with. A homogeneous equation in this sense is defined as one where the following relationship is true:

$$\textstyle f(tx,ty) = t \cdot f(x,y)$$

Solution
The solution to a homogeneous equation is to:

 * 1) Use the substitution $$\textstyle y = ux$$ where $$u$$ is a substitution variable.
 * 2) Implicitly differentiate the above equation to get $$ \frac {dy} {dx} = x \frac {du} {dx} + u $$.
 * 3) Replace $$\textstyle \frac {dy} {dx}$$ and $$\textstyle y$$ with these expressions.
 * 4) Solve for $$u$$.
 * 5) Substitute with the expression $$ u = \frac {y} {x} $$ Then solve for $$\textstyle y$$.

The advantage of this method is that the function is in terms of 2 variables, but we simplify the equation by relating $$\textstyle y$$ and $$\textstyle x$$ to each other.

Differential equations/Integrating factors

Definition
If the expression $$M(x,y) dx + N(x,y) dy = 0$$ is not exact or homogeneous, an integrating factor $$I(x)$$ can be found so that the equation: $$I(x)M(x,y) dx + I(x)N(x,y) dy = 0$$ is exact.

Solution
There are 2 approaches to a solution.
 * 1) If the function is of the form $$\frac {dy}{dx}+p(x)y=r(x)$$, then the integrating factor is $$I(x)=e^{\int p(x) dx}$$. OR  If the function is of the standard form $$M(x,y)dx+N(x,y)dy=0$$ , then the integrating factor is $$I(x)=e^{\int \frac {M_y-N_x}{N} dx}$$ or $$I(x)=e^{\int \frac {N_x-M_y}{M} dy}$$.
 * 2) Substitute the integration factor into the equation $$I(x)M(x,y)dx+I(x)N(x,y)dy=0$$ and solve.


text:
Differential equations/Change of variables

Definition
In a differential equation, if a certain term appears many different times, a substitution can be made similar to a $$u$$-substitution.

Solution

 * 1) Substitute a term for a variable (e.g. $$\textstyle u=\frac {2y}{x}$$).
 * 2) Implicitly differentiate the variable (e.g. $$\textstyle \frac {du}{dx}=\frac {2}{x} \frac {dy}{dx}$$).
 * 3) Solve for the derivative that needs to be solved (e.g. $$\textstyle \frac {dy}{dx}=\frac {x}{2} \frac {du}{dx}$$).
 * 4) Solve the original equation in terms of $$u$$ and then use the substitution for $$u$$ to get the original equation back in terms of $$x$$ and $$y$$.

A second order differential equation has a given function and terms including the first and second derivatives of that function. There are many techniques that are employed to find solutions to these problems. Different types of problems need different techniques to solve them.

Definition
For second order differential equations, a homogeneous equation is one where the right hand side is zero (e.g. $$y''+by'+cy=0$$ ).

Solution

 * 1) A general solution to this equation is $$y=e^{mx}$$ . Substitute this into the equation.
 * 2) After dividing by the exponential part, the equation should resolve to the form $$m^2+bm+c=0$$.
 * 3) Solve the quadratic equation using the quadratic formula to get the roots of $$m$$.
 * 4) If there are 2 roots, the solution is $$y=Ae^{m_1 x}+Be^{m_2 x}$$ . If there is 1 root, the solution is $$y=Ae^{mx}+Bxe^{mx}$$.

Differential equations/Linear inhomogeneous differential equations

Definition
A non-homogeneous second order equation is an equation where the right hand side is equal to some constant or function of the independent variable. This technique is best when the right hand side of the equation has a fairly simple derivative.

Solution
The solution is divided into two parts and then added together by superposition. The first part is obtained by solving the complimentary (homogeneous) equation. The second part is obtained from a set of equations. To illustrate the solution, we will take the equation $$y''+2y'+y=x^2$$ as an example.
 * 1) Solve the homogeneous equation ($$y''+2y'+y=0$$) and get the roots of the characteristic equation ($$(m+1)^2=0, m=-1$$).
 * 2) Plug the roots into the general solution ($$y_c=c_1 \sin(x)+c_2 \cos(x)$$) to obtain the complementary (homogeneous) solution.
 * 3) To get the typical (specific) solution to the differential equation, we need to choose a "solution" from a table.
 * 4) $$1$$ (any constant): $$A$$
 * 5) $$5x+7$$ : $$Ax+B$$
 * 6) $$3x^2-2$$ : $$Ax^2+Bx+C$$
 * 7) $$x^3-x+1$$ : $$Ax^3+Bx^2+Cx+D$$
 * 8) $$\sin(4x)$$ : $$A \cos(4x)+B \sin(4x)$$
 * 9) $$\cos(4x)$$ : $$A \cos(4x)+B \sin(4x)$$
 * 10) $$e^{5x}$$ : $$Ae^{5x}$$
 * 11) $$(9x-2)e^{5x}$$ : $$(Ax+B)e^{5x}$$
 * 12) $$x^{2}e^{5x}$$ : $$(Ax^2+Bx+C)e^{5x}$$
 * 13) $$e^{3x}\sin(4x)$$ : $$Ae^{3x} \cos(4x)+Be^{3x} \sin(4x)$$
 * 14) $$5x^{2}\sin(4x)$$ : $$(Ax^2+Bx+C)\cos(4x)+(Ex^2+Fx+G)\sin(4x)$$
 * 15) $$xe^{3x}\cos(4x)$$ : $$(Ax+B)e^{3x} \cos(4x)+(Cx+E)e^{3x} \sin(4x)$$
 * 16) Choose the "solution" that best fits the right hand side of the equation. (the solution of $$\textstyle x^2$$ must take the form $$\textstyle y_p = Ax^2+Bx+C$$ ).
 * 17) Differentiate the "solution" to get the derivatives of the solution ($$y_p^{'}=2Ax+B, y_p^{''}=2A$$ ).
 * 18) Substitute those solutions into the left hand side of the original differential equation ($$(2A)+2(2Ax+B)+(Ax^2+Bx+C)=x^2$$ ).
 * 19) Collect and compare like terms to solve for the coefficients ($$A=1, B=-4, C=6$$ ).
 * 20) Substitute the coefficients back into typical "solution" ($$y_p=x^2-4x+6$$ ).
 * 21) Add the typical and the complementary solutions to get the complete solution

 * $$y=y_c+y_p=c_1 \cos(x)+c_2 \sin(x)+x^2 -4x+6$$

Definition
A non-homogeneous second order equation is an equation where the right hand side is equal to some constant or function of the independent variable. This technique is best when the right hand side of the equation has a fairly complicated derivative.

Solution
This technique involves solving the complementary equation and using both solutions ($$y_1$$ and $$y_2$$ ) as a basis to solve for two more particular solutions that combine to form the typical solution $$y_p=u_1(x)+u_2(x)$$. To illustrate, let's solve the differential equation $$y''-2y'-1=2xe^{3x}$$. y_1(x) & y_2(x) \\ y_1^{'}(x) & y_2^{'}(x) \end{vmatrix}=\begin{vmatrix} e^x & xe^x \\ e^x & e^x(1+x) \end{vmatrix}=e^{2x}$$ 0 & y_2(x) \\ f(x) & y_2^{'}(x) \end{vmatrix}=\begin{vmatrix} 0 & xe^x \\ 2xe^{3x} & e^x(1+x) \end{vmatrix}=-2x^2e^{4x}$$ y_1(x) & 0 \\ y_1^{'}(x) & f(x) \end{vmatrix}=\begin{vmatrix} e^x & 0 \\ e^x & 2xe^{3x} \end{vmatrix}=2xe^{4x}$$
 * 1) Solve for the complementary solution ($$(m-1)^2=0, m=\pm 1, y_c=e^x+xe^x$$ ).
 * 2) Take each term in the complementary solution and make them separate functions ($$y_1=e^x, y_2=xe^x$$ ).
 * 3) Set up the following three Wronksian matrices and take the determinants of them:
 * 4) $$W=\begin{vmatrix}
 * 1) $$W_1=\begin{vmatrix}
 * 1) $$W_2=\begin{vmatrix}
 * 1) Solve for the terms $$u_1^{'}=\frac {W_1}{W}=\frac {-2x^2e^{4x}}{e^{2x}}=-2x^2e^{2x}$$ and $$u_2^{'}=\frac {W_2}{W}=\frac {2xe^{4x}}{e^{2x}}=2xe^{2x}$$.
 * 2) Integrate them to get the terms $$u_1=\frac {-(2x^2-2x+1)e^{2x}}{2}$$ and $$u_2=\frac {(2x-1)e^{2x}}{2}$$.
 * 3) Combine them with the complementary solution to get the complete solution ($$y=y_c+y_p=c_1 e^x+c_2 xe^x-\frac {(2x^2-2x+1)e^{2x}}{2}+\frac {(2x-1)e^{2x}}{2}$$).

Differential equations/Power series solutions

Definition
A power series solution to a differential equation is a function with infinitely many terms, each term containing a different power of the dependent variable. The general solution has the form $$y=a_0+a_1 x+a_2 x^2+a_3 x^3+\cdots$$.

Solution
To illustrate how to use the power series method to arrive at a solution, let's take the equation $$y''+x^2y'+xy=0$$.
 * 1) Start with the general form of the power series: $$y=a_0+a_1 x+a_2 x^2+a_3 x^3+\cdots$$
 * 2) Take derivatives of the general power series until an equation exists for every order of derivative in the equation. You can shift the nth term so that all the terms end with $$x^n$$ . For example,
 * 3) $$y'=a_1+2a_2 x+\cdots+na_n x^{n-1}$$ or in alternative form, $$y'=a_1+2a_2 x+\cdots+(n+1)a_{n+1} x^n$$
 * 4) $$y''=2a_2 +3\cdot2a_3 x+\cdots+(n+2)(n+1)a_{n+2} x^n$$
 * 5) To find a "recursive" solution, compare the general nth terms of each equation and substitute them into the original differential equation. If there are dependent variables in the differential equation, you might have to alter the nth term to get all the powers of the dependent variable the same. For example:
 * 6) $$y''=(n+2)(n+1)a_{n+2} x^n$$
 * 7) $$x^2 y'=x^2 \lbrack (n-1)a_{n-1}x^{n-2} \rbrack = (n-1)a_{n-1}x^n$$
 * 8) $$xy'=x \lbrack a_{n-1}x^{n-1}=a_{n-1}x^n \rbrack$$
 * 9) $$\lbrack (n+2)(n+1)a_{n+2} x^n \rbrack + \lbrack (n-1)a_{n-1}x^n \rbrack + \lbrack a_{n-1}x^n \rbrack = 0$$
 * 10) Divide by the $$x^n$$ term and solve for the highest subscript coefficient ($$a_{n+2}=\frac {-na_{n-1}}{(n+1)(n+2)}, n=1,2,3,\cdots$$ ).
 * 11) Successive iterations produce more terms in the solution. For example:
 * 12) For $$n=1: a_3=\frac {-a_0}{2\cdot3}=-\frac{a_0}{3!}, n=2: a_4=\frac{-2a_1}{3\cdot4}=-\frac{(2)^2a_1}{4!}, \cdots$$
 * 13) Some terms, like $$a_2$$, do not exist because $$n=0$$ for that case.
 * 14) Sometimes the solution can be split up into two or more functions, each dependent on a base coefficient. For example:
 * 15) $$y=y_1(x)+y_2(x)$$
 * 16) $$y_1(x)=a_0-\frac{a_0}{3!}x^3+\frac{(4)^2a_0}{4!}x^6-\frac{(4)(7)a_0}{7!}x^9+\cdots$$
 * 17) $$y_2(x)=a_1 x-\frac{(2)^2a_1}{4!}x^4+\frac{(2)^2(5)^2a_1}{7!}x^7-\frac{(2)(5)(8)a_1}{10!}x^{10}+\cdots$$

Differential equations/Laplace transforms

Definition
For some problems, the Laplace transform can convert the problem into a more solvable form. The Laplace transform equation is defined as $$L(f(t))=\int_0^\infty e^{-st}f(t) dt=F(s)$$, for the values of $$s$$ such that the integral exists. There are many properties of the Laplace transform that make it desirable to work with, such as linearity, or in other words, $$L(\alpha f(t)+\beta g(t))=\alpha L(f(t))+\beta L(g(t))$$.

Solution
To illustrate how to solve a differential equation using the Laplace transform, let's take the following equation: $$y''+2y'+y=0, y(0)=1, y'(0)=1$$. The Laplace transform usually is suited for equations with initial conditions.
 * 1) Take the Laplace transform of both sides ($$L(y''+2y'+y)=L(0)=0$$ ).
 * 2) Use the associative property to split the left side into terms ($$L(y'')+2L(y')+L(y)=0$$ ).
 * 3) Use the theorem $$L(y')=sL(y)-y(0)$$, and by extension, $$L(y'')=s^2L(y)-sy(0)-y'(0)$$ to modify the terms into scalars and multiples of $$L(y)$$ ($$s^2L(y)-sy(0)-y'(0)+2 \left [ sL(y)-y(0) \right ] +L(y)=0$$ ).
 * 4) Solve for the Laplacian ($$L(y)=\frac {s+3}{s^2+2s+1}=\frac {s+3}{(s+1)^2}$$ ).
 * 5) Take the inverse Laplace transform of both sides to get the solution, solving by method of partial fractions as needed: ($$L(y)=\frac {s+1+2}{(s+1)^2}=\frac {1}{s+1}+ \frac {2}{(s+1)^2}, y(t)=e^{-t}+2te^{-t}$$ ).
 * 6) For reference, here are some basic Laplace transforms:
 * 7) $$L(1)=\frac {1}{s}$$
 * 8) $$L(t^n)=\frac {n!}{s^{n+1}},n=1,2,3,\cdots$$
 * 9) $$L(e^{at})=\frac {1}{s-a}$$
 * 10) $$L(\sin at)=\frac {a}{s^2+a^2}$$
 * 11) $$L(\sinh at)=\frac {a}{s^2-a^2}$$
 * 12) $$L(\cos at)=\frac {s}{s^2+a^2}$$
 * 13) $$L(\cosh at)=\frac {s}{s^2-a^2}$$
 * 14) For reference, here are some theorems for the Laplace transforms:
 * 15) $$L(e^{at}f(t))=F(s-a)$$
 * 16) $$L(t \cdot f(t))=-F'(s)$$
 * 17) $$L(f^{(n)}(t))=s^n F(s)-s^{n-1}f(0)-s^{n-2}f(0)\cdots$$
 * 18) $$L(f(t-a) \cdot U(t-a)=e^{-as}F(s), a>0$$

Applied analysis

Applied analysis is the study of limits, differentiation, integration, and series as they apply to real world problems. The more theoretical side of the subject is Abstract Analysis, which deals with how one can perform all of these operations inside of more exotic sets and spaces than the familiar real and complex numbers.

Walsh spectrum of Boolean functions
The Walsh spectrum of a Boolean function is the product of it's binary string representation and a Walsh matrix.

The background pattern of white and red squares in the resulting matrix shows the binary Walsh spectra. In the following cases, they form binary Walsh matrices:

LDU decomposition of a Walsh matrix
Positive numbers are green, the zero white, negatives red. The ones in the lower and upper triangular matrices form Sierpinski triangles. The entries of the diagonal matrix are from Gould's-Morse sequence.

Product of a Walsh matrix and Gould's-Morse sequence
Concider a Walsh matrix of order 2n and a column vector with the first 2n values from with the signs distributed like the ones in sequence.

Their product always has the first 2n values from (like Gould's sequence, but with powers of 3 instead of 2) and the signs are distributed like:
 * the zeros in Thue-Morse sequence for odd n
 * the ones in Thue-Morse sequence for even n

"n-ary Walsh matrices"
The product of matrices made of consecutive numbers in the n-based numeral system gives an "n-ary Walsh matrix", when modulo n operations are used. In the following files the result for normal operations is shown in light gray numbers.

In each row and column, except the one with only zeros, there is an equal number of entries for the same value.

Quaternion group
The quaternion group can be defined via matrix multiplication in different ways:

Theory Design Lab/Defence against the dark arts

Defence against the dark arts
—On education (Über Pädagogik), Immanuel Kant Unlike the world of the Harry Potter novels there are no dark arts in the real world, unless you choose to name something so, of course. This module is named after the subject Defence Against the Dark Arts in the Harry Potter novels mostly for humorous reasons.

Almost magical effects
Are there real-world effects that might appear as wizardry, seen from a certain perspective?

Predestination
An example could be predestination as a metaphor for lack of planning. From the perspective of the planner there is no magic involved. From the perspective of the unsuspecting observer some of the effects could appear almost like magic. One defense against this form of magic would be mentoring.

 * Example:
 * How is it possible that the best pupils know the topics of the lesson in advance? Surely they will not have read ahead in the school book, or even learned something beyond the school book in their free time?

Psychology
Knowledge of psychological effects can also appear as wizardry from the perspective of the unsuspecting observer.

Especially cognitive biases may lead to observations where the unsuspecting observer may behave less rational and less sensible than the informed person and where the informed person may gain an advantage through his knowledge of psychology. Prejudices, group effects and social cohesion could also be seen to have "magical effects" on the unsuspecting observer.

 * See also: Observer-psychology effect

Knowledge
The science fiction author Arthur C. Clarke is often quoted as saying: "Any sufficiently advanced technology is indistinguishable from magic". Obviously any sufficient knowledge and technology can appear as wizardry from the perspective of the unsuspecting observer.

 * Example:
 * What did the Native Americans at first think about the steam locomotive?

Karma
Many religions claim that there is something like karma. If this were the cases then, for the unsuspecting observer again, the world might exhibit inexplicable phenomena that could amount to magical effects. Consequently one could see "good karma" as a necessary means of self-defence. Unfortunately different cultures and religions have quite different notions what karma would be. Some religions, for instance, recommend vegetarianism. Thus the question would remain: Whose theory of karma would apply?

 * See also: Karma theory

Economy
Companies could be seen to exert "magical forces" on customers and employees. The defenses against this form of magic would be consumer protection, strike action, ethical consumerism and demanding corporate social responsibility in the workplace.

Your account will be renamed
Hello,

The developer team at Wikimedia is making some changes to how accounts work, as part of our on-going efforts to provide new and better tools for our users like cross-wiki notifications. These changes will mean you have the same account name everywhere. This will let us give you new features that will help you edit and discuss better, and allow more flexible user permissions for tools. One of the side-effects of this is that user accounts will now have to be unique across all 900 Wikimedia wikis. See the announcement for more information.

Unfortunately, your account clashes with another account also called Boom. To make sure that both of you can use all Wikimedia projects in future, we have reserved the name Boom~enwikiversity that only you will have. If you like it, you don't have to do anything. If you do not like it, you can pick out a different name.

Your account will still work as before, and you will be credited for all your edits made so far, but you will have to use the new account name when you log in.

Sorry for the inconvenience.

Yours, Keegan Peterzell Community Liaison, Wikimedia Foundation 23:31, 17 March 2015 (UTC)

Renamed
 This account has been renamed as part of single-user login finalisation. If you own this account you can |log in using your previous username and password for more information. If you do not like this account's new name, you can choose your own using this form after logging in: . -- Keegan (WMF) (talk) 06:04, 19 April 2015 (UTC)

Hi, Dancemagicblackham,

I noticed you added your name to the French Stream page. This is not a page I am familiar with, but having looked at the talk page, there seems to have been very little activity since 2007, so I think you might well find that nothing is going on here.Leutha 07:24, 11 July 2011 (UTC)
