True Science: A similar Doppler Effect costume is available for sale online.
SEASON 1 -“THE TANGERINE FACTOR”
TV Science: We bet many people were able to understand the Schrödinger’s cat thought experiment because of the show. Penny was also in the dark about Edwin Schrödinger, the Austrian physicist's idea. The test is centered around a cat placed inside a box with a vial of poison that will break open at a random time. The cat can be regarded as both being dead or alive until the box is opened.
Sheldon narrated the theory to Penny as a means to aid her decision about going out with Leonard or not. She was concerned that going out with Leonard could affect their friendship. Leonard was also worried, and he approached Sheldon. He instantly understood Sheldon's advice when he gave Schrödinger’s cat as a means of counsel. Eventually, both Leonard and Penny went for the date and were ready for whatever would happen after.

True Science: When Howard brings the space toilet to Leonard and Sheldon’s apartment to work on, he also comes along with a box of supplies that resembles the things the astronauts on the ISS have. This is an adulation to the scene in 1995’s Apollo 13. In the scene, Ken Mattingly, and the NASA team have to develop an improvised repair for emergency harm caused by an oxygen tank explosion. They had to make this happen by using only the materials that look like the supplies, Jim Lovell, Jack Swigert, and Fred Haise had on their craft.
SEASON 2 - “THE MONOPOLAR EXPEDITION”
Sheldon is the winner of a National Science Foundation grant. His prize is a three-month, all-expenses-paid trip to the North Pole. There, he would endeavor to detect magnetic monopoles.

The opinion she provides is that of Sheldon, who feels Leonard's work is gotten from a completed project by Netherlands scientists.
True Science: The episode tag affirms Sheldon’s belief that if Koko the gorilla could be introduced to sign language, he should be able to teach Penny fundamental physics. Penny isn’t impressed by it but accepts to be Koko. Then Sheldon gets more derogatory; he tells Penny:
“Not likely. Koko learned to understand over 2,000 words.”
SEASON 3 - ”THE EINSTEIN APPROXIMATION”
TV Science: Sheldon isn’t making any headway while trying to solve a physics challenge - "Why electrons possess no mass when traveling through graphene."

At last, he finds inspiration in Albert Einstein, his hero.
Following the manner Einstein discovered special relativity while working in the Swiss patent office, he hopes to find a job. He indeed makes progress while serving as a busboy and working at the Cheesecake Factory as a server.
True Science: Graphene was a big topic in 2010. University of Manchester scientists Andre Geim and Konstantin Novoselov earned a Nobel Prize in Physics that year for their outstanding experiments with the material. The material which is the strongest, lightest and thinnest is referred to as the future due to its immense potentials.
SEASON 3- “THE STAIRCASE IMPLEMENTATION”
TV Science: Leonard has been operating a top-private government project, involving military rocket fuel. He comes home with some to astonish his girlfriend, Joyce Kim.
