It is unavoidable. In this age of top ten lists, coolness factor and obsessions with all sorts of numbers, someone will sooner or later construct a top ten coolness number list. Mathematician Cam McLeman just comes up with one: the top ten coolest numbers.
His choice is interesting, especially since the usual suspects, 0, 1, i, π and e are excluded. His explanations are a little difficult for non-Mathematician likes me. However, you may note how significant prime numbers are mentioned. This includes illegal primes, which is central to many computer applications, such as DVD encryption. In general, number theory is an important mathematics foundation for computer science, especially useful in cryptography.
And the coolness number according to McLeman? It is 163 and to understand the rationale, you will need to read its “many eerily related properties,” such as the fact that “it is the largest value of d such that the number field Q(sqrt(-d)) has class number 1.” For me, it is satisfying to know that my office number is cool.
