 Dec3 awarded Talkative Dec1 comment $e$ to 50 billion decimal places It becomes even more incredulous when you realize that you only need 55 digits of pi to draw a circle with the radius of the universe to the accuracy of the radius of a hydrogen atom. Nov24 comment Methods to see if a polynomial is irreducible I'm not able to access the first link you posted Nov23 comment Why would I want to multiply two polynomials? @J.M. You are right that the actual solution involves a single polynomial. But if you are doing Laguerre polynomials by hand they are (well, can be) defined through a recursion relation and thus require you to multiply polynomials together.

Nov23 comment Converting an explicitly defined function to a recursive one Recursion (n) - See: Recursion Nov19 awarded Nice Question Nov15 comment A root? Or two roots? I was under the impression that those are just two ways of saying the same thing. Nov12 comment Can the phase of a function be extracted from only its absolute value and its Fourier transform's absolute value? Just curious. How would one even define the phase of a constant function? Nov12 comment Making meaning of mathematical “bridges” Personally I find the "full" version of the formula ($e^{i\theta} = \cos{\theta} + i\sin{\theta}$) of which this "identity" is a special case to be much more beautiful and revealing Nov9 comment What's so “natural” about the base of natural logarithms? I would think that very few function are eigenvectors of the Derivative operator. In fact, I'd be curious to know if there are any others besides the exponentials and even some sums of sinusoidals/hyperbolics. Nov5 comment Is It True that We Can Never Be Sure of Validity of a Mathematical Proof? The only solution is to train more quality mathematicians so that our peer-review process can be more comprehensive and accurate. On the serious side, results that are very specialized (like the proof of fermat's last theorem) can spend a long time in review before they are published for this very reason. Nov5 answered Which one result in mathematics has surprised you the most? Nov4 comment Is speed an important quality in a mathematician? @mike too true unfortunately. I've lost many points on exams that had I had more time to think I would have solved completely. There must be some middle ground between the free for all of a take home exam (there are not very many questions you can ask on an undergraduate exam that won't be proven in some book) and the stressful race of a sit-in exam. Nov4 comment Is speed an important quality in a mathematician? It sure helps on mathematics exams!
