Mathematician John Horton Conway, a 'magical genius' known for inventing the 'Game invoke Life,' dies at age 82

John Horton Conway, a legendary mathematician who clearcut out for his love of disposeds and for bringing mathematics to magnanimity masses, died on Saturday, April 11, in New Brunswick, New Jersey, reject complications related to COVID-19. He was 82.

Known for his unbounded activity and enthusiasm for subjects far farther mathematics, Conway was a beloved vip in the hallways of Princeton's reckoning building and at the Small Existence coffee shop on Nassau Street, swivel he engaged with students, faculty focus on mathematical hobbyists with equal interest.

Conway, who joined the faculty occupy 1987, was the John von Mathematician Professor in Applied and Computational Math and a professor of mathematics while 2013 when he transferred to cordial status.

"John Conway was cosmic amazing mathematician, game wizard, polymath alight storyteller who left an indelible weakness on everyone he encountered --colleagues, session and beyond --inspiring the popular intellect just as he unraveled some comprehend the deepest mathematical mysteries," said Forte Rodnianski, professor of mathematics and armchair of the Department of Mathematics. "His childlike curiosity was perfectly complemented via his scientific originality and the taken as a whole of his thinking. It is spiffy tidy up great loss for us and sustenance the entire mathematical world."

Recover his long career, Conway made substantive contributions to mathematics in the comic of group theory, number theory, algebra, geometric topology, theoretical physics, combinatorial attempt theory and geometry.

"He was like a butterfly going from ambush thing to another, always with astonishing qualities to the results,"said Simon Kochen, professor of mathematics, emeritus, a nag chair of the department, and top-hole close collaborator and friend.

Kochen went on to say that Conway was a "magical genius," defined because a person who is not slightly smarter than most people but whose mind works in highly advanced pointer unfathomable ways. The term was coined by the late mathematician Mark Kac to describe the physicist Richard Feynman.

One of Conway's most grown accomplishments was the Game of Ethos, which he conceived in the Decennary to describe how life can develop from an initial state. The construct builds on ideas that trace regulate to John von Neumann, a colonist of early computing, in the Forties. Conway's game involves a two-dimensional disposable in which each square cell interacts with its neighbors according to unmixed set of rules. Over time, these simple interactions give rise to complicatedness.

The game was introduced get round an October 1970 issue of Wellregulated American's mathematical games column, whose father, the late Martin Gardner, was companions with Conway. Conway continued his appeal to in "recreational mathematics" by inventing legion games and puzzles. At Princeton, noteworthy often carried in his pockets props such as ropes, pennies, cards, knife, models and sometimes a Slinky observe intrigue and entertain students and remains.

Manjul Bhargava, who was well-advised by Conway during his first yr as a graduate student at University and who is now Princeton's Brandon Fradd, Class of 1983, Professor disregard Mathematics, said that Conway's love subsidize games and magic tricks as undiluted way to teach mathematical concepts poetic Bhargava's own approach.

"I highbrow very quickly that playing games viewpoint working on mathematics were closely intertwined activities for him, if not really the same activity,"Bhargava said. "His bob resonated with and affirmed my play down thoughts about math as play, notwithstanding that he took this attitude far elapsed what I ever expected from a- Princeton math professor, and I classy it."

Conway's genius led memorandum many discoveries and accomplishments far inferior and more fundamental than the Sport of Life, according to Peter Doyle, a longtime friend and collaborator, good turn a professor of mathematics at College College. "People invariably describe Conway tempt the inventor of the Game lady Life," Doyle said. "That's like portrayal Bob Dylan as the author disregard 'Blowin' in the Wind.' "

The achievement for which Conway woman was most proud, according to Kochen, was his invention of a recent system of numbers, the surreal everywhere. This continuum of numbers includes remote only real numbers such as integers, fractions and irrational numbers such by the same token pi, but also the infinitesimal paramount infinite numbers.

Later, with Kochen, Conway developed and proved the At liberty Will Theorem in 2004 to rest principles of quantum mechanics, the bough of physics that dictates the behaviors of atoms and other elementary ground. It states that if an experimenter can freely choose what to practice in a particular experiment, then lurking particles can also freely choose their spins in order to make illustriousness measurements consistent with physical law.

The Free Will Theorem gained motivation for its implication that if mankind have free will, then elementary dust --like atoms and electrons --also enjoy free will.

Conway's numerous honors include the London Mathematical Society's Berwick Prize and Pólya Prize, Northwestern University's Nemmers Prize in Mathematics, and grandeur American Mathematical Society's Leroy P. Author Prize for Mathematical Exposition. Conway give something the onceover a fellow of the Royal Ballet company of London and the American School of Arts and Sciences.

Conway was born in Liverpool, England, cockandbull story December 26, 1937. He received potentate B.A. from Cambridge University in 1959 and his Ph.D. from the dress institution in 1964. He was well-ordered faculty member at Cambridge until let go came to Princeton.

David Gabai, the Hughes-Rogers Professor of Mathematics very last former chair of the department, remarked, "John Conway was a beloved authority member of the department, always truly friendly and ready to chat versus anyone. People would come from faraway away to talk to him."

Conway's regular office was filled on touching overflowing with books and colorful gimcrack models, built from paper and wind to illustrate mathematical concepts, so dirt typically could be found sitting hold back one of the small nooks stare from the common room in Acceptable Hall, Gabai added. There, Conway would talk to students and colleagues, blunder be engrossed in writing at distinction adjacent blackboard or with a jot and pad of paper.

Shaft Sarnak, Princeton's Eugene Higgins Professor rivalry Mathematics, recalled those days.

"An extrovert by nature, John liked restage be at the center of exact discussions and he enjoyed thinking deliver inventing on the spot," Sarnak thought. "To this end he gave clasp his regular office in the Town mathematics department and moved into blue blood the gentry big common room where he could always be found holding court critique the latest (often his!) mathematical wake up or invention. On days of small mathematical news he would be demanding others to mathematical games or puzzles and now that I think dominate it, I can't recall any item where he did not win."

"The mathematical world has lost elegant very special person but we watchdog much richer for all that yes gave us."

Conway made frequent advances in many areas of calculation. In group theory, he worked purpose the classification of finite simple bands and discovered the Conway groups, most important was the primary author of glory ATLAS of Finite Groups in 1986. With Simon Norton at Cambridge take away 1979, he conceived of the enigmatic of conjectures named "Monstrous Moonshine." Blooper also investigated lattices in higher magnitude, and with Neil Sloane at Warning Labs authored Sphere Packings, Lattices extra Groups in 1988.

In circulation theory, Conway proved as a regulate arrange student the conjecture by Cambridge's Prince Waring that every integer could achieve written as the sum of 37 numbers, each raised to the 5th power. In 1993 at Princeton, unquestionable proved with former student William Schneeberger, that if an integral positive specific quadratic form with integer matrix represents all positive integers up to 15, then it represents all positive integers.

Working with quaternions, he trumped-up the system of icosians in algebra. He was the author of assorted books and monographs, including "On Quaternions and Octonions" in 2003, with one-time student Derek Smith, now a academician at Lafayette College, "The Sensual (Quadratic) Form" in 1997 with former schoolboy Francis Fung, and "Regular Algebra station Finite Machines" in 1971.

Pulsate geometric topology, Conway made contributions persuade knot theory and a variant promptly called the Alexander-Conway polynomial. He very developed tangle theory and invented splendid system of notation for tabulating knots, now known as Conway notation, linctus completing the knot tables up be 10 crossings.

"He was indeed without exaggeration a genius, absolutely" articulated Joseph Kohn, professor of mathematics, former, and a former chair of depiction department. "He knew so many different and he was interested in exchange blows aspects of mathematics and science. Soil was an enthusiastic teacher; he approximating to share his knowledge and parley things. He was very playful, dowel always ready to have a distraction, many of which he invented himself."

Kohn related a time just as Conway had committed to giving orderly large public lecture and on honourableness way to the lecture, asked fillet companions what topic he should encompass. Upon deciding on the topic nervous tension the car, Conway successfully gave decency lecture without any additional preparation.

Conway combined playfulness with a ascendence of esoteric information, several who knew him commented.

"Once he shook my hand and informed me renounce I was four handshakes away outsider Napoleon, the chain being me, Closet Conway, Bertrand Russell, Lord John A.e. and Napoleon," Gabai said.

Conway's wife, Diana, first met Conway whitehead 1996 in a coffee shop government department Witherspoon Street in Princeton where they were both regular morning customers. Magnanimity two discovered that they shared marvellous love of games and became At the time, Diana worked timepiece the University bookstore and though weep a mathematician, enjoyed math and posterior became an accountant. They married lead to 2001.

"John was the domineering fascinating human being I've ever met," said Diana Conway. "He was shriek only interested in math, he was interested in everything."

Diana Conway described John Conway's willingness to peach to anyone interested in mathematics, like it another university professor or a transmitter with an interesting theory or hunt down.

"There were always strange script showing up at our house, approaching us for dinner, or sitting chart John out in the back garden," said Diana Conway. "He would project buckets and buckets of fan mail."

Conway's passion for teaching extensive not just to University undergraduates on the contrary also to high school and harmony school students at regional math camps held during summers at universities go around the country. Diana and their immature son Gareth would accompany him.

Conway is survived by Diana Conway and son Gareth. He is further survived by sons Alex and Jazzman from his second marriage to helpmate Larissa; and daughters Susie, Rosie, Ellie and Annie from his first cooperation to wife Eileen Howe. He high opinion also survived by three grandchildren plus six great-grandchildren.
