And yet it only takes ten poles if you build the fence around something. Mar21 comment Is there such a thing as proof by example (not counter example) Obligatory xkcd. Nov24 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. Nov24 comment Adding imaginary number to exponential of Euler Gamma function It diverges for every real number n, but not necessarily for complex numbers. Oct30 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.

Added plot Oct10 answered How to obtain an approximate expression for $\sqrt{\varepsilon}$ where $\varepsilon \ll 1$? Oct10 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. Sep19 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: $1-(\frac{3}{4})^2$. Sep18 comment Why is the probability of having 2 boys 7/15?
