And of course, besides these grand concepts, inside the number pi there are lots of kinky midget porn too.

This is part of an infographic by the CBC. It shows that most of the musicians who have a doctorate degree have that degree in a field of science. I have discussed this graph previously on my main site. The number of science/math PhDs in the graph is actually proportional with the number of science/math PhDs overall.
I remember it up to the sixth digit.

Real men do their Fourier analysis by hand. And by hand I mean I usually enter fft(x) in Matlab by my bare hands. Yeaaah.

The Fourier transform takes an input function f (in red) in the “time domain” and converts it into a new function f-hat (in blue) in the “frequency domain”. In other words, the original function can be thought of as being “amplitude given time”, and the Fourier transform of the function is “amplitude given frequency”.
Shown here, a simple 6-component approximation of the square wave is decomposed (exactly, for simplicity) into 6 sine waves. These component frequencies show as very sharp peaks in the frequency domain of the function, shown as the blue graph. In practice, these peaks are never that sharp. That would require infinite precision.
