# Recreational Math Books – Part II

In my previous post (see here) I mentioned some interesting puzzle books. In today’s post I will mention different type of recreational math books i.e., biographical books. Here are my top three books in this category. They are must-read books for anybody even remotely interested in mathematics.

There are about three mathematics : (1)  Andrew Wiles, whose determination to solve Fermat’s Last Theorem inspires future generations and gives a strong message that patience and focus are two of the most important assets that every mathematician should posses. (2) Paul Erdos, whose love for mathematics is so deep and prolific and (3) Srinivasa Ramanujan, whose story is different from any other mathematician ever.

This is one of the first “recreational” books I read. It starts with the history of Fermat’s last theorem (FLT), discusses the life style of early mathematicians and moves on to talk about Andrew Wiles’s 8 year long journey proving FLT. Watch this BBC documentary for a quick overview of Andrew Wiles’s story.

Paul Erdos is one of the greatest and most prolific mathematicians ever. The title of my blog is inspired by one of his famous sayings “My Brain is Open”. I don’t want to reveal any details of this book. You will enjoy this book more if you read it without knowing anything about Paul Erdos. I should warn you that there are some really tempting open problems in this book. When I first read this book (during my PhD days) I spent almost one full semester reading papers related to Twin Prime Conjecture and other number-theoretic problems. I also wrote a paper titled “A generalization of Erdos’s proof of Bertrand-Chebyshev’s theorem”. Watch this documentary “N is a number” for a quick overview of Paul Erdos’s story.

This is a very dense book. I bought it five years back and only recently finished reading it. This books covers lots of “topics” : south indian life-style, Hardy’s life, Ramanujan’s proofs and his flawed proofs, his journey to work with Hardy, his health struggles etc. It is definitely worth-reading to know the details of Ramanujan’s passion for mathematics.
