Every generation, each cell in the automaton may transition to a new state depending on a set of rules. Sure it was cool game and it's a succinct headline that the general audience will understand, but it kinda sweeps under the rug all the incredible mathematics the man did. More details. Retrieved from "https://www.explainxkcd.com/wiki/index.php?title=2293&oldid=190505" Come to … The raptor's on vacation. Well, he thought of the game of Life as one of his less impressive accomplishments, and was moderately annoyed that it was the main thing people knew him for. You get into problems once you start machine-gunning out gliders (offsets will eventually overflow or awkwardly lose precision, depending on the var-types used; and maintaining a longer and longer bubble, or more and more bubbles just above glider-sized, is probably your other challenge) but it's probably good enough for most purposes. It is the 6th memorial comic, but it is the first released in almost 5 years, since 1560: Bubblegum. (The third author, Elwyn Berlekamp, died a year ago.) Momerath (talk) 05:02, 14 April 2020 (UTC), Interesting to see if the next comic is also a Covid-19 comic, because then it will be the 19th covid-19 comic... --Kynde (talk) 10:53, 14 April 2020 (UTC), I really think this should not be regarded as a Covid-19 comic, since it's a memorial one and the cause of death is not important for this comic. You and me both, friend. I mention this to point out that it was really Martin Gardner's article in SciAm in October 1970 that showed the game to a pretty wide public, although admittedly few people were in a position to program it at the time. Can anybody point me to a truly infinite grid implementation? If an "alive" cell has no live neighbors, or only one live neighbor, it becomes "dead". The black cells are "alive" and the white cells are "dead". He felt like it was trivial, at least compared to his other work. In the biblical age of 103, so possibly nobody even bothered to check for the cause. Eighth generation. I find it fitting that Conway died on a Doomsday (Saturday for 2020).Tovodeverett (talk) 05:41, 17 April 2020 (UTC), Should we perhaps add an explanation as to what the evolving configuration symbolizes, for the sake of readers with different cultural backgrounds? I never got so teary-eyed seeing a glider :(, Same, it’s like his spirit has gone off to be with all the other mathematicians who died doing what they love, I've come to learn that John would have hated his continued association with the game of Life.*. Your influence in modern maths is matched only by your influence on kids everywhere who were amazed by that 2-bit creature gliding across their screen. Press question mark to learn the rest of the keyboard shortcuts, https://www.numberphile.com/podcast/john-conway-tribute. The remains of the chaos down below will take two more generations to disappear completely. was there a placeholder comic posted before the gif went live? Rather, because it is so simple a child can understand it (and a reasonably clever child can implement it), it inspired a generation of mathematicians and computer scientists. Some patterns do not evolve at all ("still lifes"), some enter a cyclic, repeating state ("oscillators"), and some reproduce their own pattern displaced by an offset, resulting in patterns that can move across the grid under their own power ("gliders" and "spaceships"). I've never seen any implementation that actually produces an infinite, nor even practically infinite grid. It will continue to progress, cycling through these four states every four generations. 828 votes, 59 comments. Cellular automata was also referenced in 505: A Bunch of Rocks. This means you're free to copy and share these comics (but not to sell them). Conway was my favorite mathematician and he hated being know only as the creator of the game of life. I heard you used a goto? The glider returns to its first shape, pointing right instead of up. A cellular automaton is a machine composed of cells, each of which can be in a different state. If a "dead" cell has exactly three live neighbors, it becomes "alive". This would have been the perfect alt text. 162.158.91.101 22:26, 13 April 2020 (UTC), Given the cause of death, should this comic be listed among the Covid-19 series? -- https://twitter.com/standupmaths/status/1249105201992171522 172.69.22.146 00:04, 17 April 2020 (UTC), The thing I remember Conway for (in addition to Game of Life) is discovering the Doomsday rule/algorithm for determining days of the week (see https://en.wikipedia.org/wiki/Doomsday_rule). ;), New comments cannot be posted and votes cannot be cast. With all due respect to John Conway, The Game of Life is way more than a fun toy. 162.158.91.101 22:26, 13 April 2020 (UTC) New comments cannot be posted and votes cannot be cast, Press J to jump to the feed. Press question mark to learn the rest of the keyboard shortcuts. Not exactly, he also came back to liking it a bit later. Conway's definitely was not infinite, he even commented at length about the boundary formations that show up at the grid edges (which are among the most subjectively beautiful, incidentally).
