What is Schrodinger's cat? - Definition from WhatIs. Schrödinger's cat is a famous illustration of the principle in quantum theory of superposition, proposed by Erwin Schrödinger in 1935.
Schrödinger's cat serves to demonstrate the apparent conflict between what quantum theory tells us is true about the nature and behavior of matter on the microscopic level and what we observe to be true about the nature and behavior of matter on the macroscopic level -- everything visible to the unaided human eye.
Here's Schrödinger's (theoretical) experiment: We place a living cat into a steel chamber, along with a device containing a vial of hydrocyanic acid. There is, in the chamber, a very small amount of hydrocyanic acid, a radioactive substance. If even a single atom of the substance decays during the test period, a relay mechanism will trip a hammer, which will, in turn, break the vial and kill the cat. The Big Bang Theory. Over time, supporting characters have been promoted to starring roles: Leslie Winkle, a physicist colleague at Caltech and, at different times, a lover of both Leonard and Howard; Bernadette Rostenkowski, Howard's girlfriend (later his wife), a microbiologist and former part-time waitress alongside Penny; neuroscientist Amy Farrah Fowler, who joins the group after being matched to Sheldon on a dating website (and later becomes Sheldon's girlfriend), and Stuart Bloom, the cash-strapped owner of the comic book store the characters often visit.
In February 2014, CBS CEO Les Moonves confirmed an eighth season, when announcing the first half of the new season would air on a different night, due to CBS acquiring the rights to Thursday Night Football games.

He had selective mutism, which did not allow him to talk to women outside of his family unless he was under the influence of alcohol (or medication), until the season 6 finale.
