Mar 21 comment Is there such a thing as proof by example (not counter example) Obligatory xkcd. Nov 24 comment Adding imaginary number to exponential of Euler Gamma function I did check. It's not empty, but I'm still figuring out when it will and will not converge. Nov 24 comment Adding imaginary number to exponential of Euler Gamma function It diverges for every real number n, but not necessarily for complex numbers. Oct 30 comment How can I quantify the amount of space required to store all possible 128kilobit mp3s? Very crudely: 2^2,840,000 = (2^4)^(2,840,000/4) = 16^710,000 > 10^710,000 > 10^80. Oct 10 awarded Editor Oct 10 revised How to obtain an approximate expression for $\sqrt{\varepsilon}$ where $\varepsilon \ll 1$? Added plot Oct 10 answered How to obtain an approximate expression for $\sqrt{\varepsilon}$ where $\varepsilon \ll 1$? Oct 10 comment Integral One-to-one functions in 3 dimensions Note however, AlbertH's solution provides a unique integer for every unique tuple. To ensure the same for a function mapping to integers in the range of one to n requires knowledge of all tuples that are yet to be mapped. Sep 19 comment Why is the probability of having 2 boys 7/15? Probability of having two boys (1/4), multiplied by the probability of having at least one of them born in spring. That's $\frac{3}{16} + \frac{3}{16} + \frac{1}{16}$, or alternatively: $1-(\frac{3}{4})^2$. Sep 18 comment Why is the probability of having 2 boys 7/15?
