The code to generate this cartoon is in my answer to the XKCD-ification question. When executed in Mathematica, there is even a secret mouse-over message.

comment Unexpected result from FullSimplify
It is not zero. {FullSimplify[Y //. {Q -> Sqrt[3/(16 A)], A -> 1}] // N, FullSimplify[Z //. {Q -> Sqrt[3/(16 A)], A -> 1}] // N} gives {3.4641, 4.5} so here is at least one value of A for which the two are not equal.

comment Calculating the recursion at the Fourier domain
In the code above you have not defined ff1 or gg1 so it is not clear what you are trying to do. Why are you loading Needs[FourierSeries]? What's wrong with FourierTransform and InverseFourierTransform? And if you are going to do it numerically, then Fourier and InverseFourier should be the correct commands.

How is this question different from your previous - and what is wrong with those answers? mathematica.stackexchange.com/q/33790/1783

comment How to solve a signaling game in Mathematica (game theory)
What do you mean by "solve"? The article you link to describes the game but not a solution. Can you point to the kind of solution you wish for in some other computer language?

comment Evaluating an expression a second time returns wrong result
It looks to me as if you are using the variable i in three different ways in the same expression. What are you really trying to accomplish?

comment How can I recover the source code from cdf file?
Open the .cdf in Mathematica. Then "save as" in the notebook .nb format. Now read it back into Mathematica. If it is not immediately visible, select all then enter and the cell will open as it executes.
