Corrected entry: When Howard is asking Sheldon engineering questions, the first question is "How do you quantify the strength of materials?" Sheldon answers "Young's Modulus," and Howard admits that is correct. But it's not correct - Young's Modulus quantifies a material's rigidity, not strength.
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
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
Corrected entry: The proposition that danishes wouldn't exist if Copenhagen were flooded is wrong, because "danishes" were created by Austrian bakers. They are called danish in English-speaking countries because they're very popular in Denmark. The Danish word for this pastry is wienerbrød, which translates to "Viennese bread."Tanngrisnir
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.
Corrected entry: When Amy is putting on make up with Penny's help, where Amy says "I'm going to video chat Sheldon" she is not wearing glasses. The shot moves to capture Penny's face and Amy is wearing glasses, then the next shot shows Amy is not wearing her glasses.
Corrected entry: At the end of the episode, Sheldon runs off to Texas. That would be impossible in the short time frame the episode was set in. Especially since they live in Pasadena, California. California is 18 hours away by car from Texas. It has also been stated previously that Sheldon dislikes cars and airplanes a lot.
Corrected entry: When the guys are locked in the basement, the door hinges are on their side. You would think a theoretical physicist, experimental physicist, astrophysicist, and NASA engineer could together figure out to simply take the pins out of the hinges.
Corrected entry: It's revealed that Sheldon rents out a storage unit that contains literally everything that he has ever owned in his lifetime. How is it that nobody else has ever known about this? He doesn't drive, nor does he take public transportation, and we can assume that he must make regular trips there to store any item that he no longer needs/uses. So he would surely need to be driven there by someone, most likely by Leonard, and he obviously couldn't keep it a secret as to why he needs to go there.
Corrected entry: Several times throughout the show, Leonard makes reference to having sleep apnoea, a condition where the airways close up when you are asleep and you stop breathing for periods of time before your body's reflexes kick in and wake you up. However we also see him sleeping numerous times but he doesn't have any form of cpap (Continuous Positive Airway Pressure) machine. This is vital for anyone who has sleep apnoea as it pumps air into the users airways via a nasal cannula or face mask to keep the airways open and stop the user from stopping breathing. Since sleep apnoea in the most extreme cases can cause death (depending on type of sleep apnoea) a cpap machine is vital and should be seen whenever we see Leonard sleeping or in bed.A Demon
Corrected entry: Sheldon is very particular about sitting in his spot and not allowing anyone else into his spot. We learn later on in the series that he has been this way since Leonard moved in. However at the very end of this episode, we see Leonard sat in Sheldon's spot and Sheldon sat in the arm chair.
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.
Corrected entry: When Leonard is standing outside the apartment his hair is tucked under the band of the wireless cam he has on his head, but when he is crawling on his hands and knees through the apartment his hair is out from under the band and is hanging in front of his face.Jacy Sorkenn
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
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.

Corrected entry: In the discussion between Raj and Howard about "shiksa goddess" plus Sheldon's later mispronunciation of the word and Howard's correction, it is never clarified that the term applies only to a Gentile girlfriend of a Jewish man. No other relationship qualifies.MFWills
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.
Corrected entry: Sheldon claims the X-Men were named so after the X in Charles Xavier's' name. In The X-Men #1 (1963), Professor X states that mutants possess an extra power that humans do not have. Xavier then says "That is why I call my students... X-Men, for EX-tra power!"
Corrected entry: At the end of the episode Sheldon's sat nav voice asks "Can you name the four state capitals that are not served by the interstate system?" In fact, there are five, according to the Interstate System's website. Juneau, Alaska; Dover, Delaware; Jefferson City, Missouri; Carson City, Nevada; and Pierre, South Dakota.Captain Defenestrator
Corrected entry: Leonard refers to a never-ending game of "Bottle of Beer on the Wall" as having 'one times ten to the fourth' bottles of beer. One times ten to the fourth power is just one multiplied by itself a ridiculously large number of times, which equals one. That would be a very short game. Not a mistake a physicist would make.PEDAUNT
Corrected entry: In the scene where Sheldon lists the things that were stolen from the apartment, he mentions several gaming platforms including PlayStation 2 and PlayStation 3. Other than that he lists games including Final Fantasy 1 to 9. You can't play those Final Fantasy games on any of the gaming platforms he lists though (Only some HD remakes are available for the PlayStation 3, but only as downloads, so you won't be able to steal the discs because they don't exist).
xx:xx:xxSabine J. Kwak
Corrected entry: Sheldon refers to the "Hillbilly Peace Prize" in connection with Penny. Sheldon would have corrected anyone else who said such a thing. He would point out that that word "hillbilly" refers to people who dwell in rural, mountainous areas in the US primarily in Appalachia, the Ozarks, and other less well-known mountain chains. Nebraska, where Penny is from, is rural, but being a Great Plains state, has no connection at all to the term, not to mention a lack of mountains.MFWills
Corrected entry: While the group are trying to figure out how to play Halo without Howard, Leonard jokingly suggests cutting Raj in half. Raj responds, "Oh sure, cut the foreigner in half. There's a billion more where he came from." But Penny is in the room with them, so there's no way he should be able to talk in front of her, or even if he's been drinking, the fact alcohol helps him isn't realised until the next episode, so the fact he can speak with her there should have surprised everyone, including him.
Corrected entry: Leonard wonders aloud "I wonder who's going to tell his (Sheldon's) parents they're not having grandchildren." Leonard and Sheldon have been sharing the apartment for long enough for Leonard to know that Sheldon's father has been dead for a number of years, but it is at least since S1E04, when Sheldon's mother says "God rest his soul" while talking about his father.MFWills
Corrected entry: Stephen Hawking tells Sheldon he made an arithmetic mistake on page 2 of his paper. Sheldon then quickly turns pages on his paper to find the error, but Sheldon turns several pages of his paper, way past the second page, and still finds the error Stephen had noted.Casual Person
Corrected entry: Sheldon asks Missy why she doesn't tell her friends that he is a toll taker on The Golden Gate Bridge. There are no toll takers on the Golden Gate Bridge. Tolls are paid by credit or debit card, a prepaid account or by invoice to the registered car owner's address. There is no way Sheldon would not know this.
Corrected entry: Five minutes into the show, Sheldon has written down what a dice roll will tell him what to do. He rolls the dice, pauses and looks at the list to see what he has to do for that dice roll. The problem is he has an Eidetic memory and wouldn't take the time to look at the list when he can already see it in his head.terry s
Corrected entry: Sheldon is playing an online game he found. He yells to Leonard "I'm trapped in quicksand, the axe is dragging me down." Leonard then tells him to "Drop axe." Shortly after, Sheldon heads to bed, but he comes back saying "I know how to get the bucket. I can turn the axe around and use the handle to reach it." However, he does not have the axe as he has already dropped it.
Corrected entry: Sheldon steals the 35mm movie canisters and 2 exterior metal cases for "Raiders Of The Lost Ark" so that they supposedly could see it at a later date. We then see Sheldon running with the movie canisters and cases. That would not even be remotely possible as the 2 sets of film weigh approximately 140-160 pounds. Each individual reel (of which there would be a total of 4) has a weight of somewhere between 30 and 35 pounds including the film and individual canister. If you add in the weight of just 2 canisters plus the carrying cases they come in, that's well beyond Sheldon's carrying capacity.
Corrected entry: Sheldon gets Leonard to read the roommate agreement, and it talks about robots. Sheldon is not a robot, he's using a Virtual presence device, therefore Leonard is under no obligation to follow the rules of the roommate agreement.
Corrected entry: There is not a snowball's chance of Howard becoming an astronaut. He suffers from Intermittent Cardiac Arrhythmia, something about which he is completely open. 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.
Corrected entry: The "Hollermus" that Sheldon allegedly makes is not actually a Swiss breakfast dish. It is in fact simply a kind of jam made from elderberries which is quite common in most German-speaking countries. Also, judging by the ingredients on the table (eggs, milk, butter) and the food on the plate, the dish prepared by Sheldon seems most likely to be an omelette with a Vienna sausage, which is in no way traditionally Swiss.Tanngrisnir
Corrected entry: Penny storms into Sheldon and Leonard's apartment to throw her boyfriend's iPod out of their window and yell at her boyfriend who has just left. Raj then finds the iPod on his way in. However, according to the layout of the building with the front door being to the left of the elevator, the front side of their apartment building would be on Penny's side, so she should have thrown it out of her own apartment window. The window through Sheldon and Leonard's apartment would lead to the back.07marsh
Corrected entry: At the end of this episode when Penny asks to use Leonard and Sheldon's bathroom for a shower, when she goes down the hallway towards the bathroom/bedrooms, she turns past the bathroom (the door that is visible from the living room) and turns right and goes towards the bedrooms.Jack Adams
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
Corrected entry: Bernadette tells Howard that she chose the premature ejaculation project because neither of them has any heart diseases. However Howard has stated more than once that he has transient idiopathic arrhythmia. Also in the previous episode he actually emphasizes that his family has a history of heart diseases and alludes to a cave painting showing one of his ancestors clutching their chest.Tanngrisnir
Corrected entry: At the end of the episode, when Sheldon imagines going to the Grand Canyon to scream about Leonard, that's not the Grand Canyon, signs not withstanding. The location is Dead Horse Point State Park in Utah (near the town of Moab), with the view looking roughly south into Canyonlands National Park. [GPS near 38°28'12" by 109°44'30".] It's several hundred miles upriver from the Grand Canyon. [At least it is along the Colorado River.] The first national park sign looks authentic, but the small one at the overlook is fake, since that's not the Grand Canyon. And by the way, since it's just after New Year's, there would likely be snow at both the Grand Canyon and Dead Horse Point; the images used are not winter scenes.
Corrected entry: At the beginning, when Leonard has won the online auction, we see a shot of his laptop computer screen showing an Apple Safari browser window with Mac OS X window controls, but the laptop is a PC, not made by Apple. Mac OS X can only run on Mac hardware.
Corrected entry: If Howard can hack into Blizzard's database so deeply that he can get the name and address of game players, he could easily restore all of Sheldon's stolen 'items'. Hacking personal details - a player's real identity and their home address! - is hardcore, detailed work that only an expert could do, compared to which adding a few extra items to a player in the game would be child's play.
Corrected entry: Professor Crawley states he discovered a new species of dung beetle (named after him) in a rain forest in Borneo. That is impossible - dung beetles do not live in damp climates as the fecal matter upon which they live degrades too quickly when moist. You can find dung beetles in Savannah grassland, semi-arid desert, some lightly wooded areas, but a rain forest? Never.
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
Corrected entry: Leonard and Sheldon live in 4A and Penny in 4B. Yet when they go to the mailbox downstairs, Sheldon's mailbox is the upper left one while Penny's is the third or fourth one from the left. Mail boxes have to be in apartment order, not necessarily for the tenant who could remember where their box is but for the mailman to be able to use the apartment number as to placement of the mailbox. Whenever a sub carrier would do the route, he wouldn't be able to follow the random pattern.terry s
Corrected entry: In 3-14 "The Einstein Approximation" Bernadette stated that she is able to easily handle children as her Mother ran an illegal day care centre in their basement. However, in this episode she states that she hates children because her mother worked and she had to bring up her siblings, and she cannot properly react to children. So which is it? Can't be both.
Corrected entry: At the apartment, after pretending to eat some of the granola bar, Howard throws the bar and wrapper down on the coffee table. He does not pick it up again before they leave the apartment. Later, at the hospital, he takes the bar from his pocket and eats some.pinkwafer
Corrected entry: Leonard and Penny are inhaling Sulphur Hexaflouride to make their voices low. The effect can be seen to be fake for two reasons. First, their voices go back to normal instantly and on demand - the gas actually takes a while to clear. Second, when Leonard releases the balloon, it flies away; it should just fall to the floor because Sulphur Hexaflouride is heavier than air.Moose
Corrected entry: When the characters are driving in the car duringthis episode, it looks to be a black car (when they film in front of the car). When they run out of gas, there is a shot of them pulling over. The problem is, the car is white when pulling over.*BleuFever
Corrected entry: When Penny and Leonard are talking to Sheldon about their date, Sheldon refers to Schrodinger's Cat, stating "The cat in the box is both alive and dead, until you open the box and find out." Yet the precise point of the Schrodinger's Cat example is that the cat cannot be both alive and dead. Schrodinger was arguing against physicists of the time who claimed that certain subatomic particles were special and could be in opposite states at the same time; his argument was that you can't make small systems special because a large and obvious system (e.g., the cat) could always be made to depend on the state of the smaller one, and for a large and obvious system to be in opposite states simultaneously is ridiculous. Now, this is pretty obscure and the misunderstanding of Schrodinger's Cat experiment is widespread, but this is Sheldon we're talking about.Moose
Corrected entry: After Amy stalks off on Sheldon, Penny tells him off because she told him some good news about her paper being published, and he belittled her achievements while bigging up his own, trivial activities. She is very specific about what he did and why Amy reacted. How did she know all of this? She was nowhere near the table at the time and could not possibly have overheard their conversation. She might assume Amy is mad at Sheldon but she can't possibly know why.
Corrected entry: For an obsessive genius Sheldon makes a stupid mistake when he blackmails Leonard into signing a new roommate agreement - any contract signed under duress is invalid. He gains nothing from Leonard signing the new agreement as no other action on his part is required. Effectively Sheldon has got his autograph. Big deal. Leonard is free to ignore the new agreement if he feels like it - and his lawyer was there to witness the fact that he was forced against his will to sign in the first place. This also begs the question of why Priya gets in such a panic about Sheldon blackmailing Leonard by threatening to reveal details of their relationship to her parents - why didn't she just advise Leonard to sign on the dotted line, explaining later that he signed an invalid contract? It would certainly have saved her a lot of grief.
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.
Corrected entry: Howard explains the ease with which he "borrowed" the programmable robot arm thus : "You just have to take it out to your car as if you own it". Howard doesn't have a car - he has a Vespa scooter, and there is no way he could carry the robot arm on that. (While we are on the subject, how does he transport it from Sheldon and Leonard's apartment to his house?).
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
Corrected entry: In "The Loobenfield Decay" Sheldon and Leonard go to absurd lengths to avoid having to hear Penny perform because her singing voice is so horrible. But in series 2 episode 18 "The Work Song Nanocluster", series 3 episode 3 "The Gothowitz Deviation" and series 3 episode 8 "The Adhesive Duck Deficiency" (amongst others) she is shown to have a strong, pleasant singing voice, and she sings in front of both men without them objecting. They aren't just being polite - they genuinely like her singing. So, which is it?
Corrected entry: When Sheldon tells Leonard about the time travel clause, he states "in precisely five seconds." Anybody who knows anything about time travel know that you need a definitive point in time, so without having that exact date and time written down somewhere, there's no way a future version of them could arrive at that unspecified time. Sheldon's too anal to ignore something like that.Knever
Corrected entry: When Penny and Sheldon are driving to the supermarket, Sheldon is explaining the weight of the car and how it affects her braking time. He estimates the car's weight to be 4000 pounds, 140 for himself and 120 for Penny, and then rounds the total up to be 4400 pounds, when it actually should be 4260. It's extremely out of character for somebody like Sheldon to make such a basic addition mistake.LittleWildman
Corrected entry: Sheldon makes fun of Leonard's idea to go to Raj's for dinner by speculating that they could stop using the letter M, which would be "isguided and oronic. Later he says that "This is adness. Complete and utter adness. He should have said "This is adness. Coplete and utter adness., leaving the M out of the word "complete" - and there is no way a pedantic, obsessive genius like Sheldon would make a mistake like that.
Corrected entry: Sheldon states that reductio ad absurdum is "the logical fallacy of extending an argument to a ridiculous extreme and then challenging it". This is incorrect; this is the straw man fallacy. Reductio ad absurdum is the entirely valid inferential technique of demonstrating that the consequences of an argument being true result in a contradiction.Moose
Corrected entry: When Penny and Sheldon get into the car to drive to the hospital, she makes the remark, "You do have a learner's permit, right?" He answers yes and explains he has logged several simulation hours which ended badly. She already knows he has a learner's permit and about the simulations, since in season 2, "The Euclid Alternative," she was with him at the DMV when he got the permit and stood beside him during the simulation, actually hitting him in the face with a pillow to mimic an airbag when he crashed.lizbeth1fl
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
Corrected entry: Wil Wheaton tells Sheldon that he missed the convention because his grandmother died. When Wheaton later refers to a living grandmother, Sheldon realizes he has been tricked. He shouldn't - presumably Wheaton, like everyone else, has two grandmothers (mother's and father's side) and thus Wheaton announcing he has a living grandmother in no way contradicts what he said before. This alone shouldn't tip Sheldon off that Wheaton was lying.Moose
Corrected entry: Penny got a red light camera ticket while Sheldon was driving her car. She says she gave up Sheldon as the driver to the court because she didn't want to get any more points on her license. You don't get points on your license for a camera issued violation. The registered owner just gets a straight fine. A police officer has to issue a ticket at the scene to get license points.terry s
Corrected entry: At the end of the show Sheldon states on the walkie-talkie, "I spy with my little eye, a ferrous metal," Later he reveals that what he spied was the aluminum rims of a police car. Aluminum is a non-ferrous metal - definitely not a mistake Sheldon would make.allensis
Corrected entry: Kripke pumps helium into Sheldon's office to make his voice squeaky while conducting a phone interview. However, the helium is pumped in via a tube that is above the height of Sheldon's head, and helium floats in air; therefore, the helium would have accumulated near the ceiling and would not have affected Sheldon within a couple of minutes as shown.DavidK93
Corrected entry: Sheldon asks at the book store information desk if they have any books about making friends, and the employee tells him that all their books like that are for "little kids." It is unreasonable that the employee would not have been able to tell Sheldon about the very well known self-help book "How to Win Friends and Influence People," if Sheldon had not already been able to discover it through a cursory internet search.DavidK93
Corrected entry: When Leonard is explaining his thoughts to Sheldon, during the rant which includes him naming who he intends with the words she or her (eg "She: Penny, Her: Leslie), he states, "Indicating that She: Penny had no interest in me asking Her: Penny out," which makes no sense.
Corrected entry: Throughout the series Penny complains that she is broke, and is paid minimum wage at The Cheesecake Factory. She even takes on additional duties as a barmaid to try to earn extra money. We also learn that Sheldon and Leonard live together as their apartment is too expensive for one person - Sheldon says he would be happy to live alone if he 'could afford the rent'. Penny's apartment is almost identical to theirs - it can't be that much cheaper. So, if two University lecturers can't afford an apartment in that building, how on earth can a waitress on minimum wage do so?
