In The Big Bang Theory, Sheldon is a gifted teenager with IQ 187 and several degrees. Sheldon looks very different from others because of his super intelligence. Although his IQ is surprisingly high, his EQ is slightly inferior. He is used to showing off his high IQ and has no sense of humor, so he was not very popular at first.
His friends also agree that "he is the smartest person I have ever met", but he is also a vicious, conceited and paranoid person, obsessive-compulsive and seriously neat. But it is precisely because of this great contrast that the audience began to slowly accept this role and even become obsessed.
In addition, the actor who plays Sheldon is Jim Parsons,1born in the United States on March 24th, 973. He won the Emmy Award for Best Comedian four times.
