Mathematicians Of The Day
5th January
On this day in 1874, in a letter to Dedekind, Cantor asked if the points in a square can be put in one-to-one correspondence with those on a line.

On this day in 2022 Google released a Garavito doodle.
The postage stamp of one of today's mathematicians at THIS LINK was issued in 1949.
Methinks that answering this question would be no easy job, despite the fact that the answer seems so clearly to be 'no' that proof appears almost unnecessary.It would be three years before Cantor could prove the answer was "yes."

Quotation of the day
From Max Born
If God has made the world a perfect mechanism, He has at least conceded so much to our imperfect intellect that in order to predict little parts of it, we need not solve innumerable differential equations, but can use dice with fair success.
