Apparently, there were a couple of episodes where he was wrong. I am adding what I remember, but will add more if I come across them later.
In the episode, The Hamburger Postulate, Dr. Leslie Winkles corrects his wrong equation.
Sheldon: My equations, someone’s tampered with my equations.
Leonard: Are you sure?
Sheldon: Of course I’m sure. Look ...
It's just a reoccurring joke that management is lazy and how extensive the damage was. The elevator was damaged due to a malfunctioning experiment of Leonard's (He wrongly calculated the mixture for the experimental rocket Fuel he was developing), which Sheldon recognized as going critical so he placed it in the elevator. It exploded inside and took out the ...
Tod Browning's controversial cult horror film Freaks from 1932.
The central story is of this conniving trapeze artist Cleopatra, who seduces and marries sideshow midget Hans after learning of his large inheritance. At their wedding reception, the other "freaks" announce that they accept Cleopatra in spite of her being a "normal" outsider; they hold an ...
In the episode "The Hot Tub Contamination", the origins of this knocking ritual are revealed. When Sheldon was 13 years old, he once came home because they ran out of math to teach him. His mother was at a Bible study. He walked in the house expecting it to be empty and heard a sound from his parents' bedroom. When he opened the door, he saw ...
They modify them. The Big Bang Theory is filmed on the Warner Brothers Studio lot. In addition to providing locations for film and television productions, WB offers prop rental services that include design and manufacturing. The studio employs hundreds of craftsmen, designers, costumers, carpenters, metal-workers and mechanics to design any customized props ...
Chemicals + lightning = The Flash.
Sheldon is well known to love the comic character The Flash.
This shirt is an equation for how you create that character.
As you can see from the link above, the shirt actually appeared in a much earlier episode of the show, season six episode 21, which aired on April 25th, 2013, over a year before the CW version of The ...
From Penny's Wikipedia entry:
In contrast to all other characters, Penny and her father's surname
have not been revealed. Co-creator Bill Prady stated that Penny's last
name will be revealed eventually. Executive producer Steve Molaro,
however, has since stated her surname will remain a secret.
The creators of the program wanted a hallway between the two apartments but they felt that it was too thin. Adding an elevator forces the hallway to be wider.
Forcing the characters to use the stairs also enables a longer conversation as a lift would be too quick.
This was revealed by the creators in the 100 episode special for the UK TV channel e4.
The check engine light is being used as an indicator of the relative difference in general concern by Penny versus Sheldon or Beverly.
The check engine light in modern vehicles quite often indicates an issue with the emissions control system, although as commenters have noted it can cover a wide variety of vehicle faults (including those unrelated to the ...
The plot and dialog from the episode answer this. Wil Wheaton is a troll, and enjoys messing with people (remember the bowling games?). And he's most known for playing Wesley on Star Trek TNG. The Trekkie vs Jedi (Star Trek vs Star Wars fans) feud is as famous as the Hatfields and McCoys (No, not that McCoy.)
At the movies, the audience ...
As a writing device, it's far funnier to let the viewers imagination run away with the wild descriptions that Howard gives. Additionally, by not showing Howards mother, the writers are able to characterize and describe her any way they like, without having to find an actor who lives up to that description. Howard repeatedly describes his mother as having no ...
I too was asking myself this question, and had to go back and watch the movie over again. Here's how I see the movie turning out without Indiana Jones' presence.
Regardless of whether Indiana led the Nazi's to Marion, they would have found her anyways. They already knew that Abner Ravenwood had the amulet, like the U.S. Army Intelligence officers told ...
Monday Night: Thai Takeout Night(this has all the activities posted by weekday)
Tuesday Night: Cheesecake Factory night.
Wednesday Night: Halo Night/New Comic Book Night
Thursday Night: Every 3rd Thursday of each month is Anything Can Happen Thursday. The rest of them are Pizza Night.
Friday Night: Vintage Video Game night, also order Chinese ...
I don't believe Amy is correct, and it relates to a scene that isn't in the movie. We know that the nazis had the wrong length staff because they only had one side of the head piece. Other posters have argued whether or not the nazis obtain the head piece from Marion without him...let's assume they do...
I don't remember where I heard this but there's a ...
Internet searches for Cheesecake Factory waitress salaries range from $27,000-$33000. This may or may not include tips, but tips are shared with the kitchen. As you note, Penny freeloads quite a bit. Her car has had the engine-check light on forever.
Her apartment is not flashy - the elevator hasn't worked in 7 years. The PhDs across the hall are ...
A simple answer, No.
Sheldon Cooper doesn't have Asperger, he has 'Sheldony'
Some viewers have asserted that Sheldon's behavior is consistent with Asperger syndrome. The writers have stated that they did not use Asperger syndrome as a basis for the character, but instead thought of his actions as "Sheldony".Series co-creator Bill Prady stated: "We ...
Driving is kind of a social skill. You need to follow some unwritten norms like guessing when the other person is going to turn. And it also needs some level of reliance on your instinct. However, Sheldon takes every calculation to a very scientific and molecular level. He sucks in many situations where you need to interact with other people.
There's a ...
In The Romance Resonance he read a data table in a text book wrong
Sheldon: This is the very copy of The Handbook of Chemistry and Physics in which I looked up the reaction rates of mendelevium and…
Amy: And what?
Sheldon: No. No, no, no, no.
Amy: What’s wrong?
Sheldon: I’ve made a horrible mistake.
Amy: What are you talking about?
Sheldon: This table, it’s ...
It's a real obscure word that Sheldon's actor overheard and decided it was funny to use. From an interview with AOL:
"One of the writers, he used to say it, apparently in the writers' room. That's the tale I've heard. But I remember it wasn't in a script. It was one of those moments where we'd work on a scene and then you'd go and take notes from the ...
It is a reference to one of the origin stories about The Flash.
As a scientist, he was working in his lab when a lightening bolt struck some chemicals which turned him into The Flash.
That's what the equation represents.
Chemicals + Lightening Bolt = The Flash
The lightning bolt through a circle is the logo for The Flash.
Excerpt from Wikipedia
Close, but (given the context) the reference is presumably to a shit-eating-grin:
1. (idiomatic, vulgar) A broad smile indicating self-awareness that may suggest self-satisfaction, smugness, discomfort, or embarrassment.
Per OP's suggestion I am expanding my comment to an answer. (Of course, it will be nice if someone is able to find some additional information and sources.)
The following is mentioned in Wikipedia article on The Cheesecake Factory:
A fictional version of The Cheesecake Factory is used as a setting in the U.S. sitcom The Big Bang Theory. The show's ...
From collider.com on Comic Con 2012:-
A child asks Parsons, “Why does Sheldon like The Flash?”, Parsons
threw the question to the showrunners, and Prady responded that
Sheldon liked the Flash because Sheldon was bullied a lot and the
Flash was able to run away really fast.
In-universe, The Flash is very pro-science, specially physics and he is (...
Are they fans of both Marvel and DC characters?
They seem to be fans of both Marvel and DC characters, but we see more DC characters than Marvel ones.
In the S03E13, we see Sheldon agreeing with Raj's request after getting a pair of Hulk Hands signed by Stan Lee. There is also appearance of Stan Lee in S03E16, where he comes to a comic book store to give ...
It is the classic origin for his powers.
Even in the new CW Flash, Barry Allen was mixing some chemicals in his CSI lab when Star Labs had its explosion. The resulting energy wave also created some lightning, of which one of the bolts struck Barry.
His full name is Stuart David Bloom.
Stuart's family name Bloom is revealed on his Facebook page in The
Flaming Spittoon Acquisition (S05E10) when Sheldon is examining his
page, and was confirmed verbally by Raj during his Murder Mystery Night introduction in The Mommy Observation (S07E18).
Stuart's middle name David is mentioned by Howard in The Commitment
Small elements are changed such as plants and the door numbers
Noted here: How does ‘The Big Bang Theory’ staircase work?
However, in reality, there is only one hallway-staircase set on Stage 25 on the Warner Brothers lot (a separate set is available for the lobby, which connects to the stairs).
When scenes involving multiple floors are filmed, the ...
When did Raj start being able to talk in the presence of women without the need for alcohol consumption?
In Season 2, Episode 17 The Terminator Decoupling, it was shown that Raj could perfectly talk to women and be flirtatious without consuming alcohol. But Raj is shy and believes that He could only talk to women when he's drunk.
In this episode, the four ...
The quote is actually:
Come on, this is huge, Raj is going to be in People magazine. And he didn’t even have to knock up one of the Spears sisters.
She is referencing Britney and Jamie Lynn Spears, who are sisters. Both are also singers and pretty famous, not sure if it has to do with it exactly, but they both were actually on magazine covers after they ...
