This is a biography of the mathematician John H. Conway. Roberts quotes Conway throughout the book along with corroborating facts with other people who were there. Many of the mathematicians quoted in the book have their own biographies written.
The book is written with great appreciation for Conway in spite of his serial philandering and absolute rejection of all responsibility for his personal affairs. Roberts covers Conway’s suicide attempt. Of course a book about a mathematician will have math in it.
He discovered the Conway groups in mathematical symmetry. His names is in group theory, game theory, knot theory, abstract algebra, geometry and his famous creation of Conway’s Game of Life, a set of rules for propagating a pattern that generates incredible complexity.
The book is well written and at times hilarious. Most of the information comes from the author’s interviews with Conway. I read this as an audiobook downloaded from Audible. Jennifer Van Dyck narrated the book. Van Dyck is a new narrator for me and I was impressed with her ability.
