Correction: The answer Leonard gives to Penny is actually a correct scientific statement, and it doesn't indicate that he's clueless. He says "kinda like carbon atoms for a benzene ring, proximity and valence electrons". This is a correct statement. Carbon atoms are small and have 4 valence electrons, i.e., they can form 4 bonds. Due to catenation, carbon atoms have a very strong tendency to bond with other carbon atoms. Similarly, Leonard's statement suggests that they worked at the same place (hence proximity) and they were all seeking friends (valence electrons). Hence they became friends.

Thanks for the correction.

The Friendship Algorithm - S2-E13

Corrected entry: When Sheldon and Barry are rock climbing, Sheldon looks down and shouts in fear. When Barry asks "You all right there Cooper?", Sheldon answers "I feel somewhat like an inverse tangent function approaching an asymptote." An inverse tangent function approaches its asymptote in the horizontal axis, not the vertical. (00:15:55)

Correction: The vanity card at the end explains the joke. "A linear asymptote is essentially a straight line to which a graphed curve moves closer and closer but does not reach. In other words, given a function y=fn (x) with asymptote A, A represents a number that, no matter how big (or, given the function, small) you make x, y will never make it to A. The particular example Sheldon quotes is the inverse Tangent function, or Arctangent, which has two asymptotes. If you graph it, it sort of looks like a horizontal S. No matter how big you make x (that is, how far you move to the right [that is horizontally]), the function is never going to hit that top line (π/2), and no matter how small x gets (moving to the left), y is never going to be smaller than - π/2" Sheldon is saying he will never reach the top.

Correction: It is easy for a D to look like an O.

The Codpiece Topology - S2-E2

Corrected entry: Sheldon states that the "Reinheitsgebot" would have severely limited the availability of mead in 1487. This is wrong for two reasons, the first being that the most commonly known version of this law wasn't introduced until 1516 and secondly this law only defined the price and the ingredients of beer and had therefore nothing to do with other alcoholic beverages like mead. (00:00:20)

Tanngrisnir

Correction: Purity Law or "Reinheitsgebot" was actually introduced in 1487, the Bavarian Law replaced this in 1516. In addition, the law was in effect on the production of beers in the broad sense of the word, it's main purpose was to reduce the need for "precious' resources like grain wheat and rye and also reduce the usage of 'pagan' plants and materials. In addition, the existence of law only effective on beers would suggest that mead was indeed not likely highly available.

The Codpiece Topology - S2-E2

Corrected entry: Sheldon's battery runs low during Leonard's date with Leslie so he gets an extension cord but leaves the door open. As he goes down the stairs the extension cord unwinds until he can't go any further and attempts to pull it. Then Leonard gets to shut the door easily like there is no extension cord plugged into the outlet and leading out of the apartment. (00:11:20)

Yesser Rabhi

Correction: Having just watched this the lead goes slack and under the door.

The White Asparagus Triangulation - S2-E9

Corrected entry: Sheldon is an obsessive compulsive and picky person and he picks a pre-designated seat in all places. When he enters Penny's apartment to talk to her he promptly sits on the couch, which was not where he chose 'his seat' to be in the last episode of the first season. It seems out of character that he would sit there when he has a ready-chosen spot and that his nature is as it is.

Hamster

Correction: In the season 1 episode mentioned, Sheldon says he thinks it could be his spot. Not decided, so there is no reason to assume he is completely set on that spot and he could have changed it.

The Financial Permeability - S2-E14

Corrected entry: When Leonard returns from talking with Penny, the guys are playing Talisman. Stat counters are randomly placed on the board, when they should always be associated with cards. Then Howard rolls "double sixes" - in Talisman you advance your character by rolling a single die. Raj then acquires a sword without rolling - only the character that rolled would have acquired an item without additional gameplay. (00:13:45)

Laura Hinton Dean

Correction: Fountain of Wisdom, Pool of Life, and Magic Stream all put stat counters on the board to be picked up by whomever lands on them. A Horse allows one to roll two dice for movement, and Market Day or Acquisition would allow someone to acquire items out of turn.

Captain Defenestrator

The Lizard-Spock Expansion - S2-E8

Corrected entry: Sheldon suggests Rock, Paper, Scissors, Lizard, Spock as an alternative to Rock, Paper, Scissors because "Anecdotal evidence suggests that in the game of rock-paper-scissors, players familiar with each other will tie 75 to 80% of the time due to the limited number of outcomes." As a devout scientist, Sheldon would know that anecdotal evidence is no basis for reaching a conclusion because it is based on individual experience and subject to bias. (00:00:30)

Captain Defenestrator

Correction: Presumably the "anecdotal evidence" is his own experience; within his group of friends they tie 75-80% of the time.

Correction: Sheldon said that he accidentally had a sip of Red Bull. It was an accident. He didn't do it on a purpose.

Correction: The train was actually headed to San Francisco and made at least one stop when Summer Glau got off the train, since Pasadena is nearly 350 miles from San Francisco and it was not a nonstop route, the ride could take approximately eleven hours.

zendaddy621

Correction: You can see that a person is in a relationship before it is approved by the other person. It would simply say "[Name] is in a relationship" without the other person's name until it is approved, at which point it would say "[Name] is in a relationship with [other name]".

Correction: Paintball markers can easily fire two shots per trigger pull, especially when the CO2 in the tank is low.

The Codpiece Topology - S2-E2

Corrected entry: Sheldon's battery runs low during Leonard's date with Leslie so he gets an extension cord but leaves the door open. As he goes down the stairs the extension cord unwinds until he can't go any further and attempts to pull it. When Leonard gets up to shut the door there is no extension cord plugged into the outlet or leading out of the apartment.

lizbeth1fl

Correction: When Leonard gets up to shut the door, the camera doesn't pan low enough to see the outlet or the floor so there's no way to tell if the cord is plugged in or not.

Guy

Correction: Paintball markers can easily shoot two balls in one shot. They aren't as reliable as a real gun.

The Killer Robot Instability - S2-E12

Corrected entry: Kripke states that there is no guarantee that he will face Leonard, Sheldon, and Raj in the round-robin. In a round-robin, all competitors face each other in turn. It is out of character for Kripke not to be aware of this, and especially for Sheldon to not correct someone making this basic mistake.

Jay32183

Correction: Although the tournament is scheduled as a round robin, it's apparent that a losing robot may be actually destroyed and unable to compete further. MONTE would be unable to face Kripke's robot if it was destroyed in a previous match, regardless of whether it was scheduled to meet them or not.

Moose

The Bad Fish Paradigm - S2-E1

Corrected entry: When Sheldon mentions to Leonard, Raj, and Howard that he is moving out, Raj asks Leonard "Did you pronounce the 't' in often?" This statement in context implies that it makes Sheldon angry when someone pronounces the 't' in often. However, Leonard and other characters do this multiple times throughout the series with Sheldon never commenting on it.

Ashish_Agrawal

Correction: Sheldon is also very particular about things in certain episodes. It's not out of character for certain ticks to disappear and reappear throughout.

Ssiscool

Correction: She had already called them before we (and Sheldon) see her struggling with her door.

THGhost

Correction: This is due to the multiple camera angles used in the scene. The straw doesn't change angle.

Ssiscool

Correction: Raj is whispering to the other two so Penny doesn't hear him.

MasterOfAll

He's not whispering and when he does whisper in front of Penny he covers his mouth.

Ssiscool

Correction: The camera doesn't cut from Penny having two hands on the onion ring to just one hand. After Penny picks up the onion ring with two hands, the camera cuts to Raj squealing at her for a moment. She could have easily let go of the onion ring and put her hand down on her lap during this shot.

Casual Person

The Countdown Reflection - S5-E24

Factual error: There is not a snowball's chance of Howard becoming an astronaut. He suffers from cardiac arrhythmia, something about which he is completely open. "Transient" or not this is easily detectable by a simple electrocardiogram, which is a fundamental part of the many medical examinations a potential astronaut will have to pass. He wouldn't even be allowed to start basic training. Note also that during his basic training he shows signs of severe stress and trauma which would inevitably trigger a cardiac episode. Even if it didn't the fact that he was falling apart at the seams would have him removed from the programme for his own good.

The Holographic Excitation - S6-E5

Trivia: In this episode, Sheldon and Amy are trying to decide on couples' themed Halloween costumes. Sheldon is standing in front of the dry erase board. There are 2 columns written on the board. One named "Couples I Like" and the other "Couples You Like." Under the "Couples You Like" column, one of the couples is Blossom and Joey. Blossom is the name of the television character played by Mayim Bialik in the 90s and Joey was one of her brothers.

Show generally

Question: How come Raj has no problem speaking to his mother, but, when around other women, such as Penny, he immediately stops talking? Also, why does he have to whisper in someone's ear if he wants to ask Penny something?

Answer: Because Raj's selective mutism seems to be caused by women that Raj sees (on some sort of conscious or subconscious level) as a potential sexual partner. An attribute that wouldn't apply to either his sister or mother.
