Still a favourite of mine, this is perhaps the best 'popular' maths book I've yet come across. I feel the existence of such accounts is something of a niche in mathematics, since most popular books on subjects like physics tend to be largely descriptive and deliberately avoid actual results and derivations for fear of becoming inaccessible. As with Havil's text here, and others like Dunham's, Maor's, Nahin's, et al. however, in mathematics comparable popular treatments will give the lay reader a

I was hoping to find a book that went further into the rabbit hole of the gamma constant than most books. It pops up in many places, but why? Here, Havil goes further than I expected, and is easy to follow. He also remains entertaining while doing so.

And it is always interesting to end up with my favorite subject, the Riemann Hypothesis. My friends sometimes tease me for reading books on math and the Riemann Hypothesis (boring!), but they noticed my ...more

Some tidbits:

p.32-33 Kempner series = Harmonic series with those terms whose denominators having a fixed digit dropped (e.g. only sum reciprocals of numbers without a '7' in them). This is bounded by geometric series, and therefore converges.

p.39 Fun proof of sum of reciprocal squares = pi^2 / 6, appropriate for calc class, once you know Taylor series for sin.

p. 44-45 \int_0^1 1/(x^x) dx = \sum_n=0^{\infy} 1/(n^n) using Taylor series for e^x and ...more

so far so good although i always feel like an idiot when i get caught up on even the "simple" proofs. and this happens a lot.
