Frank Morgan’s Math Chat Archives


Math Chat started as a live call-in cable TV show in Williamstown (1996-97, January 2000) and Princeton (1997-98), ran as a regular column in The Christian Science Monitor (1996-1998), continued on the Mathematical Association of America website, and finally became The Math Chat Book with a $1000 Math Chat Quest. Most of the columns are archived here.
