Things you didn't know about Big Bang Theory

The title initially intended for comedy was "Lenny, Penny and Kenny."

The names of the two main characters (Sheldon and Leonard) were chosen in tribute to Sheldon Leonard, actor, director and screenwriter, who died in 1997 in Los Angeles, and who was also a physicist.

Does anyone of you ring Amy's face? This is the same actress, Mayim Bialik, who gave life to the character of "Blossom". It is curious that the actress is a real-life neurobiologist.

Sheldon's custom of giving 3 knocks when he knocks on the door was established from chapter 10 of the series.

It is curious that actor Jim Parsons (Sheldon) has acknowledged that he has not seen Stark Trek (a series that idolizes fiction).

There is only one main character in the series whose last name is unknown. It's about the neighbor's, Penny. This, which actress Kaley Couco embodies, did not appear in some episodes of the fourth season, as the young woman broke her leg.

The lullaby "Sweet Kitty" that Sheldon loves and needs to be sung when he is sad or sick, is an adaptation of "Warm Kitty," whose author is Edith Newlin.

If it is rare to find someone who plays instruments such as theremin, cello or harp, it turns out that both Jim Parsons (Sheldon), Johnny Galecki (Leonard) and Mayim Bialik (Amy) not only play them in the series, but also They do it in reality.

As you know, in the series the actors carry out a lot of scientific experiments. As it turns out they are real! They have the supervision of Professor David Saltzberg of the University of California.

Contrary to what usually happens in the world of cinema, Penny's declaration of love to Leonard was filmed at first, when the director judged it "unbeatable!".

The actor who brings Sheldon Cooper to life, Jim Parsons, had actually worked in Houston for the Microsoft Sidewalk company.

The series has been visited by celebrities from various fields. For example, comic book writer Stan Lee, creator among others of characters such as Captain America, or actors Leonard Nimoy, George Takei, Brent Spiner and LeVar Burton, of Star Trek. They have also appeared George Smoot, Nobel Prize in Physics in 2006, Michael J. Massimino, NASA engineer and astronaut, and even Stephen Hawking.
