WASHINGTON --
Have you ever noticed Sheldon wearing a t-shirt with the number '73' during an episode of Big Bang Theory?
There's a reason. It's his favorite number.
“73 is the 21st prime number. Its mirror, 37, is the 12th, and it mirror, 21, is the product of multiplying 7 and 3 … and in binary 73 is a palindrome… 1-0-0-1-0-0-1, which backwards is 1-0-0-1-0-0-1.”
Pretty cool, right?!
The CBS hit comedy will be coming to an end this month after 12 seasons. The final episode will debut on Thursday, May 16th at 8 P.M. Eastern time.
