A delight for mathematicians
on 10 May 2017
A very detailed and not too difficult overview of the second most famous number in mathematics. I loved it and refer to it often. One
of the joys is the copious graphs that so well illustrate the ideas. Good explanations of how e entered into maths and has come
almost to dominate it, and how e is related to the trigonometrical functions we learnt at school and to the square root of minus one.
This book is a valuable addition to other portraits of individual numbers, for example "Zero" by Charles Seife, or "An Imaginary Tale, The
Story of root minus one" by Paul Nahin. For those who wish to pursue e to a high technical level, I recommend "Dr Euler's Famous
Formula" also by Paul Nahin (university level). Can you guess what this famous formuls is? Don't look immediately at the next line!
It is of course e^i.pi = -1
