comment convolution square root of uniform distribution
hmm, upon further reflection it seems like there is no such pdf; the convolution of f(x) with itself would always have a maximum when it lines up.

comment numerical integration for N datapoints
Huh, never heard of Romberg integration before, thanks... What if h is fixed (i.e. velocity measurements made once every N milliseconds) rather than something that can be increased adaptively?

comment numerical integration for N datapoints
Well, I understand that part when N is small (I guess it's kind of like windowing functions in FFTs), but not when N is large.

comment closed-form expressions for product of 3n+k where k = 1 or 2
yes, I know. Read the Wolfram Alpha link. The gamma function expressions involve gamma(n+4/3) or gamma(n+5/3) which are not integer factorials.

comment constructing “pseudonoise” sequences other than (2^n)-1? (low cyclical autocorrelation)
hmm, looks like there's a lot of research on this: signalslab.marstu.net/?page_id=1769

comment How can adding an infinite number of rationals yield an irrational number?
Infinite sums have meaning, sure. But I have a finite lifetime, and each addition step takes a finite time -- therefore I cannot add infinitely many numbers. Neither can a computer, by the same reasoning. However I can use reasoning in some cases to compute the limit of an infinite sum (as could a computer in some other cases, with sufficient programming). The difference may be a bit pedantic, but this is mathematics, after all.

comment how to distribute n red and m blue balls in some containers to maximize probability of random picking a red one from them?
off-topic. Best fit is probably math.stackexchange (NOT mathoverflow.net)
