##### Update::2009.08.16

MathBabbler learned from the Arizona Republic that Babe Ruth died at the age of `53` on 16 August 1948. [Note: MathBabbler recorded this update at the age of 53-1.]

`53` is a ThurmNumber because it is 2 score 13 and both 2 and 13 are prime numbers.

`53` in base-6 is repdigit number 33 in base-10.

On 31 March 2009, MathBabbler modified the MBNA to check for Ruth-Aaron Pairs. [Note: 53 is not a member of a Ruth-Aaron pair.]
