Happy Birthday to Dana Stewart Scott! Scott received the 1976 #ACMTuringAward along with Michael O. Rabin, for their joint paper "Finite Automata and Their Decision Problem," which introduced the idea of nondeterministic machines, which has proved to be an enormously valuable concept. Their classic paper has been a continuous source of inspiration for subsequent work in this field. Scott explains how he came to write a thesis on infinite dimensional geometry: https://buff.ly/sZ3FDK7
