The Friendship Algorithm - S2-E13

Corrected entry: When Penny asks Leonard how Sheldon met Howard and Raj his answer is a long science answer that means he has no clue. That is incorrect since another episode reveals Leonard met them at school and brought them to the apartment. (00:05:00)

bcrd500

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.

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.

The Friendship Algorithm - S2-E13

Corrected entry: When Sheldon was stuck in an infinite loop in his "friendship flowchart", Howard created an escape which he labeled "LDA"; however, Sheldon referred to it as "Least Objectionable Activity", which would be "LOA."

zendaddy621

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

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 Premium member

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 passes by. A Horse allows one to roll two dice for movement, and Market Day or Acquisition would allow someone to acquire items out of turn.

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 Premium member

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

The Codpiece Topology - S2-E2

Corrected entry: Sheldon says something about drinking red bull, but he doesn't drink coffee because it's a drug, so he would avoid red bull even more.

Feather

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

The Terminator Decoupling - S2-E17

Corrected entry: On the train, the guys reference an eleven-hour train ride from Pasadena to San Diego, but it's only a 4 hour ride, at most. (00:10:00)

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.

The White Asparagus Triangulation - S2-E9

Corrected entry: Sheldon obviously changes the relationship status on Leonard's Facebook page to 'in a relationship with Stephanie Barnett'. At this point it would have been impossible for Penny to see the status update, because it only shows up after both parties have confirmed it.

Tanngrisnir

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]".

The Cushion Saturation - S2-E16

Corrected entry: At the end, Sheldon fires 5 shots at Leonard, who somehow ends up with 7 distinct paintball marks on his chest.

Jon Sandys Premium member

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.

The Cushion Saturation - S2-E16

Corrected entry: At the end of the episode, Sheldon shoots Leonard five times, but there are six stains on Leonard's armor.

Brad Premium member

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.

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.

The Barbarian Sublimation - S2-E3

Corrected entry: When Penny is having trouble unlocking her apartment door, she says she is waiting for the locksmith but she never took the time to call the locksmith.

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

THGhost

The Codpiece Topology - S2-E2

Corrected entry: When Leonard and Leslie are talking about assuming a relationship, in the cafeteria, the angle of the straw sticking out of Leonard's soda can continually changes throughout the whole scene. (00:06:05)

Hamster Premium member

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

The Panty Piñata Polarization - S2-E7

Corrected entry: Penny takes Sheldon's onion ring and holds it with 2 hands. Camera cuts and one is hand is down in her lap. (00:05:00)

Ssiscool Premium member

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 Financial Permeability - S2-E14

Corrected entry: When using the whiteboard at the beginning, Raj writes "7:11" on the board with a red marker. Later on when Sheldon returns to the apartment with Red Vines, this has vanished from the whiteboard although nobody rubbed it out. (00:01:10)

Hamster Premium member

Correction: There is a red smudge where 7:11 was written. There was enough time for Sheldon to go out get Red Vines, so there was time for him to rub it off when on his own.

The Financial Permeability - S2-E14

Corrected entry: In 'Pilot' (season 1, episode 1), Leonard and Sheldon attempt to sell their sperm for money to install a T1 line in their apartment, and in 'The Dumpling Paradox' (season 1, episode 7), Sheldon says to Leonard "Frankly, if I could afford the rent, I would ask you to leave". Yet in this episode he says to Penny, "My expenses account for 46.9% of my after-tax income". The only way that his expenses could account for less than half his income just over a year after these lines can only really be explained away if the university gave him a pay rise of over 100%, which is incredibly unlikely for many reasons.

Douglasac

Correction: There are so many possible situations that could explain all of this. Regarding his payrise, You said "unlikely" but that does not mean impossible. That aside, Sheldon could have changed his spending/expense habits. Personally, I did when I got a payrise, regardless of how much it was. Also Sheldon has also proven to us that he is capable of making sarcastic comments now and then whether he is aware he is doing it or not.

The Pork Chop Indeterminacy - S1-E15

Character mistake: In his conversation with Missy Sheldon makes it clear that his superior intelligence is a result of a random, mutated gene. Since Missy isn't similarly intelligent she obviously isn't carrying this mutated gene (which would be a billion to one shot anyway) so her offspring wouldn't inherit it. Sheldon would know this - his offspring would carry the mutated gene for superior intelligence, Missy's would not. Anyone knowing enough about genetics to use the term 'randomly mutated gene' understands enough to know that the mutated gene would only be expressed in a direct line from the carrier - Sheldon. Also bear in mind he has a model of the DNA molecule in his living room - it is obviously an interest.

Upvote valid corrections to help move entries into the corrections section.

Suggested correction: Genes can be dormant. Which allows them to skip generations. Therefor Missy's children could actually get the "mutated" gene. This is especially true since Sheldon and Missy are twins. Also, since the episode is about who out of Leonard, Howard or Raj, Sheldon would allow to "mate" with his sister, there is the added "insurance" of getting any smart genes from any of the 3 Lothario's mentioned above.

If you are going to try to argue with a geneticist about genetics, please use the correct terms. Sheldon is not referring to a recessive gene - there is no such thing as a dormant gene - he is speaking of a randomly mutated gene. Those are the words he used. If he had inherited a homozygous recessive karotype - one recessive gene from each of his parents - then somewhere in his family tree there would similarly gifted people, in which case he would use the correct term - a recessive gene. If Missy is a heterozygotic dominant karotype possessing the recessive gene for super-genius and the dominant for ordinary intelligence then mating her with Howard, Raj or Leonard would be a waste of time as their dominant genius gene would prevent the recessive super-genius gene from being expressed in the phenotype of the resulting child. The child would be highly intelligent but not on Sheldon's standards. It doesn't matter if Sheldon does not know any of this as he refers several times to a randomly mutated gene, not a recessive one. Missy does not carry the super-genius gene. The posting is correct.

Sheldon is prone to magical thinking when necessary to preserve his obsessive need to control his environment. He may have simply ignored the flaw in his reasoning, as even the most intelligent humans do when venturing outside their ares of expertise. He may be interested in the science of genetics, but his Ph.D. in physics doesn't qualify him as an expert in that field.

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.
