“Old math teachers never die—they just become irrational”

“Old soldiers never die—they just fade away” is an old saying that was popularized by General Douglas MacArthur (1880-1964) in his farewell address to Congress on April 19, 1951. Many parodies of the saying have been made.

There have been many math versions. “Old math teachers never die, they just become irrational” was posted on Twitter on April 13. 2009.

“Old mathematicians never die—they just lose some of their functions” is a related saying.
