Nine of pentacles
 

In the TV-show "The Big Bang Theory", Dr. Sheldon Cooper says that his favorite number and the best number is 73.

73 is the 21st prime number, and 37 (73 backwards) is the 12th prime number (21 backwards).

In binary code 73 is written 100001 and backwards it makes the same.

Card number 73 in the tarot deck is Nine of pentacles. This is truly what Sheldon strives for.

A look at learntarot.com shows the keywords discipline, self-reliance and refinement.

I'm definitely no Sheldon Cooper. I need Jesus Christ and my Holy father to control me.

Why doesn't Sheldon Cooper give up? His own scientific research shows that it all will end. Wouldn't it be smarter to listen to his mother and her christian faith for an eternal life - or does Sheldon just show the wrong way for the christians? Maybe he knows it himself? Maybe he is God's little showman? A real actor? :-)
