He also made contributions to many branches of recreational mathematics, most notably the invention of the cellular automaton called the Game of Life. He was 82. He died of the coronavirus. He made original contributions to group theory (the Leech lattice, monstrous moonshine), higher-dimensional geometry, tessellations, knot theory, number theory (surreal numbers), algebra, mathematical logic and analysis. The year had to be less than 1978, when Gdel died, and greater than 1970, the year Conway found the surreals. That A could do B. I think Conway himself thought it rather trivial, but for a nonmathematician like me, it was a shock to the intuition, a shattering revelation to watch glorious complexity emerging from staid simplicity., Dr. Conway was proudest of his discovery of surreal numbers. They provide a secure foundation on which Conway carefully builds a vast and fantastic edifice., But an edifice of what? He was the primary author of the ATLAS of Finite Groups (1986). Its the purest example I know of the dynamics of collective human innovation. Conway was born on 26 December 1937 in Liverpool, the son of Cyril Horton Conway and Agnes Boyce. That would need changes in our rules of life, which we take for granted. To me, the dynamics of our game resemble how grown children balance their desire to stay close to their parents with their desire to strike out on their own. The Game of Life invention adopted the name Turing complete. Another game that John invented allowed him to construct the surreal numbers. Conways partnership with Martin Gardner is not a secret. John Horton Conway in his office at Princeton University in 1993. 9781620405932 | ISBN: 978-1-6204-0593-2. It is an organic life simulation carried out on a square grid of cells, each of which is alive or dead according to how many living neighbours it has. On 8 April 2020, Conway developed symptoms of COVID-19. It is a staple of recreational mathematics. one of the most eminent mathematicians of the century.. He built a water-powered computer, which he called Winnie (Water Initiated Nonchalantly Numerical Integrating Engine). Life in Life, from a short documentary on the Game of Life by Alan Zucconi, a London-based lecturer and science communicator. He would take topic requests from students and deliver an extemporaneous lecture. After all, Conway was known for solving math problems with his bare hands. It requires a lot of focus and patience, but I assure you it can be done. John Horton Conway, who has died aged 82 after contracting Covid-19, was one of the most prolific and charismatic British mathematicians of the 20th century. He played an important role in the successful program to determine and classify all finite simple groups when he discovered what are now called the Conway groups. E-mail:web@math.princeton.edu, 2023 The Trustees of Princeton University, John Conway was born in Liverpool, England on December 26, 1937. A memorial to Dr. Conway in the Game of Life style. Today's column is a celebration of John Horton Conway, the legendary British mathematician, who died of coronavirus earlier this month, aged 82. The Martin Gardner Literary Interests/Special Collections, Stanford University Libraries, A Penrose Life oscillator known as The Bat. Animation by Susan Stepney. A decade later, he became a member of the Fellow of the Royal Society. 1937. The legendary mathematician John Horton Conway, who died in April of COVID-19, took a childlike delight in inventing puzzles and games. John made major advances in group theory. In time, Conway became the departments prize attraction, holding forth in the common room, usually doing nothing but piddling away his days playing more games. I wanted to know whether it was the rules or the grid that was the important thing. Conway was married three times. December 26, He was by far the most charismatic lecturer in the faculty, his Cambridge colleague Peter Swinnerton-Dyer once said. John Horton Conway John Horton Conway . What was Gdel like? Find the smallest tiling that is balanced, such that the addition of the next tile is as likely to increase the number of exposed edges as it is to decrease it. I had other unanswerable questions as well. In 1987 he took up the position of John von Neumann professor of applied and computational mathematics at Princeton University, New Jersey. In this moment in time, its important to emphasize that inherent unpredictability so well illustrated in even the simple Game of Life is a feature of life in the real world as well as in the Game of Life. Dr. Conway always hoped that surreal numbers might find practical applications, perhaps in helping to illuminate the universe on the cosmic and quantum scales. But Im happy to have met the great man, even if it was only for a short interval.. Conway is a seducer, the seducer, said his Princeton colleague Peter Sarnakspeaking exclusively of Conways skills as a teacher, of course. Conway realizes it wont be considered great, but he might still try to convince you that it is.. Dr. Conway, who died in April, having spent the latter part of his career at Princeton, sometimes called Life a no-player, never-ending game. Mr. Gardner called it a fantastic solitaire pastime.. And I asked him about the Surprising Assertion hed made. He was the primary author of the, In a book of some 700 pages with Neil Sloane called, In elementary geometry, he discovered many new results about triangles, for instance, the beautiful Conway circle associated with every triangle. He remained at Cambridge as a faculty member until 1986, when he joined the Princeton mathematics department as the John von Neumann Professor of Applied and Computational Mathematics. I used to go around saying, I hate Life, Dr. Conway says in the film. Unlike most games were used to but like Conways Game of Life its a no-player never-ending game, as Conway described his creation. These days it has become harder and harder for an amateur to find a newsworthy pattern without fancy software and hardware. This work made him a key player in the successful classification of the finite simple groups. Conway has made several contributions to theories such as the number theory, knot theory, coding theory, and the combinatorial game theory. John Horton Conway obituary | Mathematics | The Guardian He was active in many branches of mathematics, including group theory, coding theory, knot theory, geometry, number theory and quadratic forms, as well as in recreational mathematics. John Horton Conway was one of the most versatile mathematicians of the past century, who made influential contributions to group theory, analysis, topology, number theory, geometry, algebra and. More trivially, the game attracted a cult of Lifenthusiasts, programmers who spent a lot of time hacking Life that is, constructing patterns in hopes of spotting new Life-forms. He received his B.A. Begin typing to search for a section of this site. No one can do. There he engaged Sarnak, who arrived at Princeton in 1991, in a viciously aggressive (if ostensibly playful) competition with a spinning toy called a Levitron. John Horton Conway - Wikipedia And there were ever more games of Phutball, which Dr. Conway was not very good at. Conway had recently enjoyed his self-proclaimed annus mirabilis . Thats what chaos is about. One of Dr. Conways favorite accomplishments was the Free Will Theorem, conceptualized casually over the course of a decade with his friend and fellow Princeton mathematician Simon Kochen and first published in 2006 (and later revised). John considered the surreal numbers one of his signal achievements, one which will eventually be useful in standard mathematics. The algorithm is simple enough for anyone with basic arithmetic ability to do the calculations mentally. At Princeton he was almost invariably recruited to give the first-year course intended to persuade students to become math majors. Made of hundreds of cells, it moves two cells forward and one sideways every six generations. Conway could usually give the correct answer in under two seconds. John Horton Conway, mathematician, born 26 December 1937; died 11 April 2020. John Horton Conway in his office at Princeton University in 1993. John Horton Conway, the English-born Princeton mathematician whose body of work ranged from the rigorously highbrow to the frivolously fun, earning him prizes and a reputation as a. Dr. Conway persevered in finding the fun through triple bypass surgery, a suicide attempt and a number of strokes. But all joking aside. The Game of Lifes pulsing, pyrotechnic constellations are classic examples of emergent phenomena, introduced decades before that adjective became a buzzword. John Horton Conway FRS [2] (26 December 1937 - 11 April 2020) was an English mathematician. (The Stanford computer scientist Donald Knuth had come up with the name while writing the novelette Surreal Numbers: How Two Ex-Students Turned on to Pure Mathematics and Found Total Happiness.). He came up with the angel problem, which was solved in 2006. John Horton Conway - MacTutor History of Mathematics Archive I did some work with students looking at Life on a Penrose tiling grid, rather than the square grid. But never mind what year it was. And even after having proved the impossibility of a disproof, the issue with the infinities nagged at him. Conway had met Gdel, really and truly. Help our scientists and scholars continue their field-shaping work. Then well enjoy a geometric puzzle that relates to some of his most visually pleasing work. He read and annotated H.S.M. His most famous game is the Game of Life. | Sign up for the Science Times newsletter. That is the mathematical analysis of games such as noughts and crosses, draughts, chess and Go, as well as a wealth of original games that John and assorted collaborators devised over the decades, such as Phutball (short for Philosophers Football), a two-person board game played on a grid using one white stone (the ball) and numerous black stones (representing men), Hackenbush, and Sprouts. For instance, the group of symmetries of an equilateral triangle has six things in it: three rotations and three flips. Lenia patterns are fuzzy, thus not easy for engineering (they are mostly evolved instead), but are harder to destroy. The first is sensitivity to initial conditions. His swath was probably broader than anyone who ever lived, said the mathematician Neil Sloane, a collaborator with Dr. Conway and the founder of the On-Line Encyclopedia of Integer Sequences. Despite the simplicity of Johns defining rules, it turned out that anything that can be algorithmically computed can be done so within the zero-player Game of Life. I said to him that I thought Id discovered the correct theory of infinitesimals. In a book of some 700 pages with Neil Sloane called Sphere Packing, Lattices, and Groups (1988), they dealt with dense packing of space by spheres in different dimensions, which they applied to error-correcting codes. Arthur T Benjamin, Factoring numbers with Conway's 150 method, The College Mathematics Journal, Vol.49, pp.122-125, 2018. He also made contributions to many branches of recreational mathematics, most notably the invention of the cellular automaton called the Game of Life . Conway had discovered many (if not most) of the major properties of the tilings. This page was last modified on 17 June 2023, at 13:05. Mingling with my betters at the Institutewhere the worlds best scholars delve deep into the past, the history of humanity, the evolution of the universeI was ever answering the question from people as to how one writes about a living subject. 26 December 1937 Liverpool, England Died 11 April 2020 Princeton, New Jersey, USA Summary John Conway was an English mathematician who has produced many results in the theory of finite groups, knot theory, number theory, combinatorial game theory and coding theory. One scholar, the fabulously monikered Aristotle Socrates, an astrophysicist, spoke on Solar Systems Unlike Our Own. Conway was, by comparison, high comedy, in an orbit all his ownprankish, belligerent, hijacking the process. It took 40 years to find the coveted Snark, a stable pattern that reflects gliders 90 degrees. More specifically, he discovered three sporadic groups based on the symmetry of the Leech lattice, which have been designated the Conway groups. Conway's career was intertwined with that of Martin Gardner. Here are some questions to direct your exploration of this square-tiled world. Lavin thought the caricature vividly captured Conway as rapscallion. While he was reportedly shy as a young man, over time John developed a disarming charm and an extrovert Pied Piper persona. Life shows us complex virtual organisms arising out of the interaction of a few simple rules so goodbye Intelligent Design., Professor of complexity, Santa Fe Institute. Dr. Conways mother, a great reader, especially of Dickens, had worked from age 11. He was a multifaceted phenomenon . He attributed his success in so many different arenas to his habit of always working simultaneously on several unrelated problems: he might be stuck on most of them but suddenly have an idea leading to a breakthrough on another one. Very cunning! he said. He could be easily distracted by what he called nerdish delights. He once went on a flexagon binge, courtesy of Mr. Gardner, who described flexagons as polygons, folded from straight or crooked strips of paper, which have the fascinating property of changing their faces when they are flexed.. In this 2014Numberphilevideo, John Conway recounts how he created the Game of Life. Although having the same root, Life and Lenia have nearly opposite nature: designed versus organic, precise versus adaptive, fragile versus resilient. Mathematics: The mercurial mathematician | Nature Conway believes the surreals are great. Writing my biography of Conway (Genius At Play:The Curious Mind of John Horton Conway published last July) over several years and as many visits to the Institute from 200714, I found the date of Conways meeting with Gdel impossible to pinpoint. I first encountered Life at the Exploratorium in San Francisco in 1978. As a graduate student, he proved one case of a conjecture by Edward Waring, that every integer could be written as the sum of 37 numbers each raised to the fifth power, though Chen Jingrun solved the problem independently before Conway's work could be published. Cantors continuum problem is simply the question: How many points are there on a straight line in Euclidean space?. If anything, he is keenly disappointed that the surreals havent yet led to something greater. He had an extrovert Pied Piper persona, and his classes were invariably oversubscribed. He also wrote On Numbers and Games (ONAG) which lays out the mathematical foundations of CGT. Professor of computer science, University of York, England, In the Artificial Life community, Life is a foundational piece of work. John Horton Conway, the English-born Princeton mathematician whose body of work ranged from the rigorously highbrow to the frivolously fun, earning him prizes and a reputation as a creative, iconoclastic and even magical genius, died on Saturday in New Brunswick, N.J. He told me about the Greek and Roman tradition of vivisection, making public spectacle of strapping a live pig to a plank and cutting him open and observing the mechanics of his beating heart. John Horton Conway, investigating Life in 1974. This conjecture was later proved by his student, Richard Borcherds, who was awarded the Fields Medal for this work. John Horton Conway, who has died aged 82 after contracting Covid-19, was one of the most prolific and charismatic British mathematicians of the 20th century. Whats special about the triangles, and how do they relate to Conways work? Have fun exploring a numerical puzzle, a geometric puzzle and a game of random patterns, all inspired by the playful genius of the legendary mathematician. After leaving sixth form, he studied mathematics at Gonville and Caius College, Cambridge. In elementary school he could calculate the days of the week for any given date, (a skill he later refined into his . The words I remember are I was wrong. And I do remember the feeling of disappointment. A decade ago, John worked with the editor Peter Renz on updated versions of some of Gardners books of collected columns, again contributing fresh results of significance, including a new proof of Morleys theorem about triangles. Conway introduced the Mathieu groupoid, an extension of the Mathieu group M12 to 13 points. During a visit to the Institute in the 1970s, the mathematician John Horton Conway, then of Cambridge, spent the ten most interesting minutes of his life. John Horton Conway (1937-2020) | Science Lavin observed that Conway was in good company among artists who matched creativity with promiscuity, intellectual and/or interpersonalPicasso, for example. John Horton Conway was born in Liverpool on Boxing Day 1937 to Cyril Horton Conway, who, after leaving school aged 14, made a living playing cards before becoming a chemistry laboratory assistant, and his wife Agnes. Did he look well? Looming behind it all is our collective vision of an artificial intelligence-fueled future that is certain to come with surprises, not all of them pleasant. For most mathematicians, games and puzzles have only a minor, tangential connection with their subject. It turns out that not one but two different triangles have the exact same values of x and y! Recently, some of Lifes most steadfast friends reflected upon its influence and lessons over half a century. It was discovered by a member of Dr. Conways research team, Richard Guy, in Cambridge, England. He had three grandchildren and two great-grandchildren. John Horton Conway, a 'Magical Genius' in Math, Dies at 82. This seemingly simple board game, inspired by von Neumanns construction of a self-reproducing machine, allowed him to simulate any Turing machine. There is a mysterious 10-digit decimal number,abcdefghij. Invited to deliver a talk to the undergraduate math club at Princeton, Conway made his way across town and wangled himself a private audience with the God of logic, Kurt Gdel. He retired in 2013, when he became emeritus professor at Princeton. As a high school student, he discovered an organizational system for knots enabling, a nearly complete tabulation for knots of up to 11 crossings and discovered duplications and omissions from the existing tables from 1900 that only went to 10 crossings. A PhD (1964) followed, under Harold Davenport. The meeting came about via their mutual friend Stanley Tennenbaum, a mathematician and logician who for a time lived alone in the woods in New England, but he did the rounds through Montreal, Chicago, New York, and Princeton, the last being a regular pit stop for the purpose of talking to Gdel. Because of its analogies with the rise, fall and alterations of a society of living organisms, it belongs to a growing class of what are called simulation games, Mr. Gardner wrote when he introduced Life to the world 50 years ago with his October 1970 column. And I said, Well, what about your idea that we would learn more about the continuum hypothesis? And he said, If I said that, I was wrong. The Game of Life motivated the use of cellular automata in the rich field of complexity science, with simulations modeling everything from ants to traffic, clouds to galaxies. He currently lectures at Princeton University located in New Jersey. He invented many new games and puzzles such as Sprouts, Phutball, Conways Soldiers, and the Two Wizards puzzle. It appears that his interest in games began during his years studying the Cambridge Mathematical Tripos, where he became an avid backgammon player, spending hours playing the game in the common room.
