WebAug 28, 2015 · Take, for instance, Conway’s Doomsday Algorithm, by which he displayed his prodigious skill at naming the day of the week for any given date. Although Conway had been showing off this trick since he was a teen, the algorithm came about during a visit with Gardner. Conway flew to New York and waited for his friend to pick him up at the airport.
