John Conway has died
People here might know him best for the "Game of Life"[0], but he did so much more.  The book about Conway by Siobhan Roberts is an interesting read about the man and his work.  There's a review here.[1]<p>Some will know Conway via is work on the Classification of Finite Simple Groups (with <i>many</i> others), some via his "Look and Say" sequence, while still others will know his book "Winning Ways"[2], written with Richard Guy[3] and Elwyn Berlekamp[4].  My copy signed by all three is something I treasure.<p>I was privileged to know all three of them, and I mourn their passing.<p>[0] <a href="https://en.wikipedia.org/wiki/Conway%27s_Game_of_Life" rel="nofollow">https://en.wikipedia.org/wiki/Conway%27s_Game_of_Life</a><p>[1] <a href="https://www.theguardian.com/science/2015/jul/23/john-horton-conway-the-most-charismatic-mathematician-in-the-world" rel="nofollow">https://www.theguardian.com/science/2015/jul/23/john-horton-...</a><p>[2] <a href="https://en.wikipedia.org/wiki/Winning_Ways_for_your_Mathematical_Plays" rel="nofollow">https://en.wikipedia.org/wiki/Winning_Ways_for_your_Mathemat...</a><p>[3] <a href="https://en.wikipedia.org/wiki/Richard_K._Guy" rel="nofollow">https://en.wikipedia.org/wiki/Richard_K._Guy</a><p>[4] <a href="https://en.wikipedia.org/wiki/Elwyn_Berlekamp" rel="nofollow">https://en.wikipedia.org/wiki/Elwyn_Berlekamp</a><p><i>Added in Edit:</i><p>From his wikipedia page:<p>Known for: Surreal numbers, Conway groups, Monstrous moonshine, Doomsday algorithm, Look-and-say sequence, Icosians, Mathieu groupoid, Free will theorem, Conway chained arrow notation, Conway criterion, Conway notation (knot theory), Conway polyhedron notation, ATLAS of Finite Groups, Conway's Game of Life
