Correction: The signed napkin (from s02e11 "The Bath Item Gift Hypothesis") was from Leonard Nimoy (who played Spock) whom Penny met at the Cheesecake Factory, not Stan Lee.

Bishop73

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.

bcrd500

Correction: It's not a stupidity. It's entirely within the personalities of the two friends that Sheldon wouldn't accept change and give up something that is rightly his and for Howard to gloat over that he's a bigger deal than Sheldon now and refuse to give up something given for his new celebrity.

Correction: Sheldon didn't even have a car. Heck, he didn't even have a license. Well, except for a later episode where he secretly had a license that he never used.

terry s

This point is made several times in the episode. The fact that Sheldon does not have a car but still agues forcibly for his right to the parking space serves to reinforce the recurring theme of the show, that Sheldon is unbearably eccentric and opinionated but still manages to engage with his social group.

Correction: When bringing her to lunch with the other guys, Sheldon specifically says "You may remember Dr. Nowitski" and they reply. They obviously do remember meeting her.

LorgSkyegon

Correction: As the other correction states he introduces her by saying you may remember. Sheldon is also very literal and skeptical of Penny's memory, having had to explain most things for a decade.

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 Classified Materials Turbulence - S2-E22

Corrected entry: Why would all the astronauts want to do something as dangerous as a spacewalk, particularly one that not only leaves nobody in the International Space Station, but one that has been forbidden by NASA? Because of the smell of waste leaking from the defective toilet? If they can still smell that after they have put on their spacesuits, they are in a lot more trouble than they think. There is no need to leave the station, and they would never, ever do something as stupid as all leaving the ISS at the same time anyway. Besides, do they think the problem of the leaking toilet is going to fix itself while they are all out spacewalking?

Correction: If you can explain away technical errors like this by claiming 'suspension of disbelief' that about half of this site just became redundant. There is a definite error in the episode, identified in this posting : there would never, ever be an occasion where every astronaut would leave the ISS at the same time.

Correction: They never say anything about a smell. We can only assume a worst case-scenario, which in this case, would be their feces floating around inside the station. Of course, even something like this wouldn't put real astronauts outside, but since it's a TV show, it falls into the suspension of belief category.

Correction: That's Raj wearing a blue jacket getting condiments.

The Platonic Permutation - S9-E9

Continuity mistake: In episode 16 of season 1, Penny is talking about making a cake for Leonard's birthday and states she knows his birthday because she was checking a horoscope for him. But in this episode she does not know when his birthday is, which leads to Leonard revealing he was secretly reading Penny's diary. (00:40:00)

Suggested correction: It's certainly possible to forget something you knew eight years ago.

LorgSkyegon

This is perhaps true for two people who rarely have contact, but I would list this as a character mistake. Penny and Leonard are in a serious relationship and are married at this point.

Bishop73

This is also a couple who BOTH forgot it was their anniversary.

LorgSkyegon

I forgot my wife's birthday on a number of occasions. It's one of the reasons she is now my ex-wife.

There's a difference between forgetting and not knowing.

Bishop73

I've been married for seven years and my husband still doesn't know my birthday. It's the 24th but sometimes he thinks it's the 24th or the 4th or the 20th etc. And especially since Leonard doesn't celebrate his birthday, it's not something that's going to remain in the forefront of Penny's mind.

immortal eskimo

Correction: It wouldn't matter if they had. They hopelessly contaminated the sterile room by opening a window to allow the bird in in the first place. The bigger mistake is that some idiot allowed an unsealed window that could be opened in a sterile room in the first place.

The Holiday Summation - S10-E12

Corrected entry: Penny finds a place where they can cut a tree themselves. She states that Leonard let the axe slip from his hands but when the tree slips in the roof, we can see that the tree was cut with a chainsaw by the linear cut on the wood.

Correction: It was a farm that lets people cut down their own tree with an axe, but after you cut it down, there is normally a place at the front where you pay that will give a clean cut with a chainsaw so that the tree goes cleanly into a stand. They also will typically clean up the lower branches for the same reason.

The Vengeance Formulation - S3-E9

Corrected entry: The foam Sheldon used on Kripke consists of mixing ordinary dish soap, hydrogen peroxide, and saturated potassium iodide. That kind of exothermic reaction is dangerously flammable, so it should have severely burned Kripke and the members of the university board when it fell on them.

Correction: Correct, but I think you're confusing 'flammable' with hot. Without a source of ignition, the flammable foam would not ignite and generate heat from combustion. However, this reaction is sufficiently exothermic that the falling goop would not have had time to cool, and would likely have burned the individuals underneath. You can see this during the test in the apartment when the reaction generates copious clouds of steam.

Correction: He never specified his level of proficiency. By saying he never learned it, he may simply be saying he's not fluent in it. He knows some basic words/phrases and that's it and saying he "never learned it" is simply that he never completed education in the language beyond the basic level.

The Rothman Disintegration - S5-E17

Corrected entry: After Sheldon has told Barry about the rules of Rock/Paper/Scissors/Lizard/Spock for the first time, Barry then replies "I'm sorry, can you repeat that." When he says "repeat", he correctly pronounces the "r." However, it has already been established throughout the series that Barry pronounces all his Rs like Ws due to his speech impediment.

Casual Person

Correction: Barry doesn't always mispronounce the letter R. It can happen with certain Rs and Ls.

The Vengeance Formulation - S3-E9

Corrected entry: Sheldon caused thousands of dollars of damage to university property when he exacted his revenge against Barry Kripke in an act of blatant vandalism. Not only does he get Barry, but also the university president and other dignitaries. Sheldon would have certainly faced a disciplinary hearing, along with paying for the damages he admitted to causing. But nothing of the event is mentioned after that.

Mike Lynch

Correction: Nothing about it is mentioned in the show. Doesn't mean that he wasn't punished. He's lucky he held his job, probably. That's all we know.

lionhead

Correction: Watch closely, while she's talking to Sheldon, you see her lean and light the cigarette. There is also an occasion where she gives the monkey a cigarette but comments on not lighting it.

The Robotic Manipulation - S4-E1

Corrected entry: While driving towards the restaurant, Amy mentions she uses dandruff shampoo for her "dry" scalp. Dandruff and dry scalp have the same main symptoms, which are falling flakes and an itchy scalp, but they are two different conditions. In dry scalp, the skin gets irritated and flakes off. With dandruff, the cause is too much oil on the scalp. That excess oil causes skin cells to build up and then shed. Therefore dandruff shampoo should be used for an oily scalp, not a dry scalp. (00:11:19)

Correction: Except there are dandruff shampoos that specifically treat dry scalp. In addition, dry scalp is commonly caused by dandruff.

Bishop73

More of a continuity error regarding this is that much later she claims that lice isn't attracted to her hair cos of her naturally oily scalp (contradictory).

Then that should be entered as a mistake. What was entered isn't a mistake.

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 Big Bran Hypothesis - S1-E2

Corrected entry: Sheldon is wrong about the physics of pushing the furniture up the stairs. This is not just a question of work (energy) but also of power (energy/time). Since he and Leonard cannot produce an unlimited amount of energy per second, they may need to push it slowly, contrary to what he asserts. This is a very serious and very basic error for Sheldon considering he has a PhD in Physics.

Correction: This is wrong. Not only does he not mention energy anywhere, the commenter is not correct. This is not a mistake, just a different way of saying it (even though he didn't, rewatch the episode and find anything about work there).

Correction: However, Penny's father might not know that. Also, it could be a case that since he works as a theoretical physicist that he may have to work weekends, like when he worked nights.

Ssiscool

Correction: It's not the same work shift. Note that Howard isn't wearing the same clothes.

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.

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.
