Lucky Numbers and Stanislaw Ulam

I just uploaded a video about the so-called Lucky Numbers.

These numbers are derived using a sieve-type algorithm developed by the acclaimed mathematician Stanislaw Ulam.

The video explains what they are:



The first lucky numbers are 1, 3, 7, 9, 13, 15, 21, 25, 31, 33, 37, 43, 49, 51, 63, 67, 69, 73, 75, 79, 87, 93 and 99.

Checking a few facts, I was just reading a about Stanislaw Ulam.

It turns out he was born and dies on the 13th of the month (13 Apr 1909 - 13 May 1984).

13 is lucky number!

He lived to be 75 years old - another Lucky Number.

And the year of his birth - 1909 - was also the year a film called "The Lucky Number" was released.
