Apr 14 comment Algebra and Cancer Research@JeffH: I tried searching for it, but could unfortunately not fond the reference... Apr 14 comment Algebra and Cancer ResearchI visited a talk a while ago, where the speaker described how the dynamics of blood groups worked in a population. This gave rise to a very specific algebraic variety, and the blood group proportions that we see now today, could be explained, using this variety. This is not exactly cancer research, but definitely in the field of medicine. Apr 14 comment Dead Flies ProblemHow about defining the "average density" as $\lim_{r \to \infty} F_r/B_r$ where $F_r$ are the number of points within distance $r$ from the origin, and $B_r$ the area of a circle with radius $r$? Apr 10 awarded Nice Question Apr 10 comment Applications of really large numbersThank you! I am aware of all the sources you linked to, but they do not really satisfy me as much as I'd like (see my post edit). Surely, the numbers that appear are truly large, but the result in the end is just "this is a large number", If you asked a person in complex analysis what theory of analytic functions is good for, then she would not say "Oh, we use this to construct cool analytic functions", but rather "These particular analytic functions are used to show this other result in other area", which a priori do not really look like they need analytic functions. Apr 10 revised Applications of really large numbersclarified Apr 10 comment Applications of really large numbersIn my opinion, the interesting part here is essentially the existence and finiteness of Grahams bound, not so much the size. If the proof in some sense relies on Grahams number in an essential way, then this is an application, but if there is a lot of extra effort to find a bound of the number, then it does not add so much extra value, I think. Similarly, the recent progress of the twin prime conjecture is not really about the size of the gap between primes, but its finiteness, even though the initial number was a quite large number (70 millions).

Apr 4 comment Is there a self-consistent citation system?How about using latex+bibtex and let publisher decide which format to use? Apr 4 comment Best lecture notes in pure mathematicsHave a look at what other people have done in other areas. Personally, I like the books by R. Stanley in enumerative combinatorics.
