Erdős had some considerable peculiarities. For instance there's the anecdote about him not figuring out the proper way to open a carton of orange juice, so he used a knife to stab a hole in its side.

the actor Terrence Howard appeared on the TV show, The View, and claimed that he had proof (his own) that the square root of 2 was a rational number
laughable?
he was very serious

Incredible mathematician for sure! I went to Bell Labs many times back when it was real but never ran into her.
Understandable since my field was ion implanters, semiconductor hardware and Bell Labs had a small chip base there.
So Erdos lived with her and her husband and worked on a number of papers together.
Incredible CV!

What does that mean? 50/49 is 1.02 and change. What has that to do with 2^ 0.5?
I assume you meant the ration of 50 to 49.
1/49, like 1/7, is irrational, of course, but I thought it was an interesting way to characters rt(2) in terms we think of more often.
