Just finished Uncle Petros and Goldbach’s Conjecture: A Novel of Mathematical Obsession by Apostolos Doxiadis. It was the first book I reached for and it was a great kick-off to the readathon. The book was full of pencil markings, annoying as it is a library book, and I spent the last 100 pages erasing the marks. (Someone else will have to do the first half.)
The book is fiction, but a very lifelike tale of the joys and trials of mathematics, or in particular, being a mathematician. I recommend it for anyone interested in the field, or with a scientific bent. It is out of print but I ordered two copies on AbeBooks to scatter around to mathy people in my life.
Next up is The Detective and the Woman: A Novel of Sherlock Holmes. I met author Amy Thomas at 221B Con a couple of years ago and bought her first two books, which she kindly signed. The readathon was a good time to get at least one of them read!
