Season 2

"The Bat Jar Conjecture" is the thirteenth episode of the first season of the American sitcom The Big Bang Theory. This episode first aired on Monday, April 21, 2008.

## SummaryEdit

For the annual Bowl, the gang forms a team, but ends up throwing the obnoxious controlling Sheldon off the team. They recruit Leslie Winkle because she is good at physics and Sheldon takes them all on with his team of stand-ins.

## Extended PlotEdit

The boys are discussing the new Star Trek movie which is supposed to show Spock's birth. They ponder about Spock's [1] and generally alien to human copulation and impregnation. Penny shows up, having spilled diet Coke, yogurt, and nail polish on her laptop, causing the A key to stick. Howard discovers that one of the regular teams in the annual physics competition will not be participating in this year's Physics Bowl because they formed a barbershop quartet. Joy ensues as the boys contemplate victory in the contest. Sheldon feels participating is beneath him . His participation to asking Picasso to play Pictionary, or Noah Webster to play Boggle, or asking Jacques Cousteau to play "Go Fish". In Sheldon's view this would be inviting these famous people to trivialize their area of expertise, suggesting that he feels participating in the quizwould be 'beneath his station' When Leonard reminds Sheldon of Spock's dying words; that the needs of the many outweighs the needs of the few or the one, he relents.

Howard suggests they should name their team the Perpetual-Motion Squad (PMS), although Sheldon suggests the Army Ants, as it is the most powerful animal gram for gram. Leonard tries to point out to Sheldon that some people might misinterpret AA for something else (Alcoholics Anonymous), but he ignores Leonard. Because Sheldon threatens to quit if he doesn't get his way, the team is named Army Ants (AA). Later, during team practice, Sheldon takes it upon himself to answer every question regardless of who buzzes in first. Eventually, he even promotes himself to team captain. Sheldon's insufferable attitude is becoming too much for the team to handle, and as a result, they kick him off the team with a consolation Batman cookie jar. Devastated, Sheldon decides to form his own team. Meanwhile, Leonard, Howard and Raj now need a fourth member for their team and decide to recruit Leslie Winkle, who initially refuses. Upon hearing they will be competing against Sheldon, she agrees, as she bears a grudge against him.

On the day of the Physics Bowl, Sheldon arrives with his team, which is comprised of poorly educated people (presumably) who only serve to qualify him, as the rules state that each team must consist of four people. Both teams rapidly increase their points and, when the final question arrives, the score stands at 1150 for AA (Sheldon's team) and 1175 for PMS (Leonard's team). The last question proves too difficult for PMS, and, in the end, Leonard panics and incorrectly guesses 8.4. However, they soon notice that Sheldon doesn't have an answer either, when suddenly the third floor janitor (one of his teammates) turns out to be a former Union|Soviet] physicist (credited as ]Dimitri and portrayed by Adam Gregor) from Petersburg St. Petersburg State Polytechnical University|Leningrad Polytechnika}} and states the correct answer. In disbelief, Sheldon's pride gets in the way and denies that answer to be AA's official answer and declines to provide one after his childish demand for a different question is denied. Before the winner is announced, Leonard offers Sheldon a chance at redemption, asking if he'd rather lose by himself or win as part of a team. Sheldon simply replies that he doesn't understand the question. PMS is declared the winner, and the team celebrates (Howard tearing off his T-shirt in the process) to [2] "We are the Champions". Penny is still asleep in the audience.

In the final scene, Penny quizzes both Leonard and Sheldon about Culture, in which neither of them can answer a single question unless the incorrect answer is from Star Trek.

## Costume NotesEdit

 Muted Earth Green Lantern Robot Evolution Toxic Stripe Sheldon starts with a Muted Earth plaid tee (discontinued from Kirra). The next day he's in a green on green Green Lantern logo t-shirt. Back at the university, he sports the Robot Evolution shirt. During the Physics Bowl contest, Sheldon wears a Star Trek replica style of uniform, featuring his "AA" logo for "Army Ants". Sheldon wears command gold, while the rest of Sheldon's motley crew wears support red. After losing the Physics Bowl, he mopes at the apartment in a tee matching his mood; blue with dark red stripes (aka "Toxic Stripes" by BDG). Unknown blue mole Red Cassette Out of This World Will Fix Computer For Brains Leonard starts the episode in a "mole" t-shirt. The next day he's in a red "cassette tapes" tee - sometimes available at RedBubble.com (search for term "Leonard's cassette"). At the cafeteria, he wears the "Out of This World" green galaxy shirt; in the Physics Bowl, Leonard's team sports blue t-shirts bearing the abbreviation P.M.S. (for Perpetual Motion Squad) and in the final scene at the apartment, he's sporting a geeky Walking Dead shirt, stating "Will Fix Computer For Brains" from Jinx Clothing (discontinued). Detail of Leonard's "Will Fix Computer For Brains" tee: Checkered belt Checker buckle Checkerboard Vans Star buckle Howard's theme this episode is checkerboards. He wears a black and white checkerboard belt with matching buckle, as well as Vans shoes in blue and white checks and in rainbow checks. This episode also features the first appearance of his star belt buckle.

## Set NotesEdit

• The key item for this episode is obviously the "Bat Jar". This jar was manufactured in a limited run on 3,600 - so finding one can be tough. Years ago they were plentiful enough that Overstock.com had them for about \$80, but now they can only be found in a local comic shop, collectibles dealer, or use eBay to find these.
• In the cafeteria, Sheldon is seen studying up for the Physics Bowl by reading Heavy Quark Physics, by Aneesh Manohar and Mark Wise.

## TriviaEdit

• The scene from Star Trek that Howard describes depicting Spock's birth was cut from the final movie, although it's included as a deleted scene.
• Spock's dying words ("The needs of the many outweigh the needs of the few, or the one."), which inspires Sheldon to join the team are from the movie "Star Trek II: The Wrath of Khan".
• Sheldon suffers from carpal tunnel syndrome, which he refers to as an "old Nintendo injury". He is later seen wearing a wrist brace during the competition.
• The Batman Jar Leonard buys Sheldon is seen frequently in future episodes.
• Raj speaks to Penny sober, though inadvertently, by agreeing with Howard that the story of Zod is a good one.
• Although Raj does not speak to (or in front of) Penny, he laughs his "Cruella de Vil" laugh at Sheldon when he, Leonard and Howard confront Sheldon just before the start of the Physics Bowl.
• Sheldon designs uniforms that are emblazoned with the initials "AA", which he designed to mean "Army Ants", though Leonard points out it could imply something else (likely implying "Alcoholics Anonymous"), though Sheldon misses the point and guesses "Anodized Aluminum" as the next most likely acronym expansion. Though, the other team's name isn't much better; 'Perpetual Motion Squad', a double entendre reference to a violation of the of thermodynamics laws of thermodynamics and being able to go all night, abbreviates to PMS, more commonly associated with "Premenstrual syndrome". Later, when Leonard gives Leslie Winkle the team's t-shirt, she replies "PMS? A few days early!".
• Raj suggests "the actress who played TV's Blossom" for their physics bowl team to replace Sheldon. That actress would be Mayim Bialik, and she does have a Ph.D. in neuroscience. Coincidentally, Mayim Bialik joins the show in the Season 3 finale and becomes a regular cast member in Season 4 as Dr. Amy Farrah Fowler. Raj also says, "How about the girl from The Wonder Years?" He is referring to Danica McKellar, who has a degree in mathematics, coauthored a physics theorem, and appears in the Season 3 episode "The Psychic Vortex" as Abby.
• Sheldon's Spanish is very bad. Apparently, he could not differentiate the Spanish words hijo and carnicero to ascertain if his third teammate was the son or butcher of his second.
• Sheldon's long-winded insult of "I'm a polymerized tree sap and you're an inorganic adhesive so whatever verbal projectile you launch in my direction is reflected off of me, returns on its original trajectory and adheres to you." is a much longer (and detailed) version of "I'm rubber and you're glue; whatever you say bounces off me and sticks onto you."
• "Leningrad Polytechnika" most likely refers to the Saint Petersburg State Polytechnical University in St. Peterburg, Russia (formerly, Leningrad, U.S.S.R.).
• It's surprising that Leonard (and P.M.S.) won a trophy for a non-championship match. When Dr. Gablehauser first introduces the teams, he states that it is "today's preliminary match." Unless there were only a few teams in the tournament, it is unlikely that they would get a trophy for an early-round victory.
• The first question of Penny's popular culture quiz is about the TV series "The Brady Bunch". In 2000, actress Kaley Cuoco played Maureen McCormick (i.e. Marcia Brady) in the movie "Growing Up Brady" about the behind the scenes story of the TV series.

## GoofsEdit

• Sheldon also makes a categorical error in this episode. When Howard says he should answer the engineering questions since he is an engineer, Sheldon compares this to him answering all the anthropology questions because he's a mammal. Anthropology is the study of humans, not mammals; all humans are mammals, but not all mammals are humans. He ought to have said 'mammalogy', or claimed he was a human.

## Episode QuestionEdit

• When Sheldon was kicked out of the team, Sheldon got very angry and was determined to take revenge. This reaction is strange as he did not even want to take place in the Physics Bowl competition as shown at the beginning of the episode.
• More information about the questions asked during the Physics Bowl and during the practice round with Penny (The questions or answers written inside "()" indicate that both are not mentioned in the episode, or are somewhat to be true, or are generated by viewers):

### Penny'sEdit

• What is the shortest light pulse ever produced? 130 attoseconds (billionths of a billionth of a second and the new record is now 80 attoseconds) [5]
• What is the quantum mechanical effect used to encode data on hard disk drives? Giant magneto resistance
• What artificial satellite has seen Albert Einstein's predicted frame-dragging?

### Physics BowlEdit

• What is the isospin singlet partner of the pi-zero meson? Eta meson
• What is the lightest element on earth, with no stable isotopes?
• What is the force between two uncharged plates due to quantum vacuum fluctuation?
• How does a quantum computer factor large numbers?
• (What is the mechanical work necessary to produce 1 cal of heat?) 4.1855×107 ergs/cal
• (What theory proposed that the temperatures of two adjacent bodies will equalize due to the transfer of heat energy by radiation and absorption?) Prèvost's theory of exchanges
• (?) $\lambda=\frac{1}{\pi r^2 N}$
• (At what temperature does an iron magnet lose its magnetic field (the Curie temperature/point)?) 770 degrees Celsius (Howard's answer of 760 (the temperature of the young lady in the front row) was incorrect)

The final question asks to solve what looks to be the following equation: $\left ( 2 \pi \right )^4 \int \left [ \bar{v}^{(s_2)} \left ( p _3 \right ) \left (i \sqrt{4 \pi \alpha}\gamma^\mu \right ) v^{(s_1)} \left ( p _1 \right ) \right ] \frac{i g_{\mu\nu}}{q^2} \left [ \bar{v}^{(s_4)} \left ( p _4 \right ) \left ( i \sqrt{4 \pi \alpha}\gamma^\mu \right ) v^{(s_2)} \left ( p _2 \right ) \right ] \times \delta ^{(4)} \left (p _1 - p _3 - q \right ) \delta ^{(4)} \left ( p _2 + q - p _4 \right ) d^4 q$

PMS guesses 8.4, which is incorrect, while AA has no official answer, one of Sheldon's teammates suggests $-8\pi\alpha$, which turns out to be the correct answer.

Actually $-8\pi\alpha$ is not really the correct solution of the equation shown above, but it would take some effort to get the right answer, which surely won't be as simple as given in the show. Additionally, there's an error in this equation; if it should correspond to the Feynman-Diagram standing above it and if the answers should not have an open index $\nu$, because $\nu$ isn't contracted, then the second gammamatrix needs to have the index $\nu$. Even if one corrects that, one has to square this Matrix element (expression) and sum over the Spins $s_1,s_2,s_3,s_4$ to get a better result than just the whole expression. Even then, the answer depends on some kinematic variables. If interested in calculating that, look in ’s "An Introduction to Quantum Field Theory" pages 131ff.

## Penny's QuizEdit

Penny brings in what looks to be cards from a Pursuit game, to settle once and for all, who's smarter between Sheldon and Leonard. She asks them:

After her questions, it turns out that Leonard and Sheldon have trouble understanding pop culture and seem to be mainly smart in their comfort zone of science and other general knowledge. Like, when Penny asks the Tweety Bird question, Sheldon struggles to know the answer and comes up with Romulan, which Penny with her attitude of sarcasm says "yes". However, when Leonard hooks up with Penny in the third season, he has a much better understanding of it.

## QuotesEdit

[After the Physics Bowl, Penny is making Leonard and Sheldon answer Trivial Pursuit questions]

Penny: Tweety Bird tawt he taw a what?

Sheldon: [thinks for a second] Romulan?

Penny: Yes.... he tawt he taw a Romulan.

Leslie: Hello, Sheldon.

Sheldon: [looking terrified] Leslie Winkle!

Leslie: Yeah, Leslie Winkle! The answer to the question, "Who made Sheldon Cooper cry like a little girl?".

Sheldon: Yes, well, I'm polymerized tree sap and you're an inorganic adhesive, so whatever verbal projectile you launch in my direction is reflected off of me, returns on its original trajectory and adheres to you.

Leslie: [sarcastically] Ooooh... ouch.

Penny: Good afternoon, and welcome to today’s physics bowl practice round. I’m Penny, and I’ll be your host, because apparently I didn't have anything else to do on a Saturday afternoon, and isn't that just a little sad? Gentlemen, are you ready?

Howard: Okay, we’re going to need a strong fourth for our team.

Raj: You know who’s apparently very smart, is the girl who played TV’s "Blossom". She got a PhD in neuroscience or something.

Leonard: Raj, we’re not getting TV’s Blossom to join our physics bowl team.

Raj: How about the girl from "The Wonder Years"?

Howard: Gentlemen, I believe I've found the solution to all our problems.

Leonard: We can’t ask Leslie Winkle.

Raj: Why? Because you slept together and when she was done with you she discarded you like last night’s chutney?

Leonard: Yes.

Dimitri: The answer is minus eight pi alpha.

Sheldon: Hang on, hang on a second, that's not our answer. What are you doing?

Dimitri: Answering question. Winning physics bowl.

Sheldon: How do you know anything about physics?

Dimitri: Here, I am janitor. In former Soviet Union, I am physicist. Leningrad Politechnika. Go, polar bears.

Sheldon: Well, that's a delightful little story, but our arrangement was that you sit here and not say anything, I answer the questions.

Sheldon: Hey, look, now maybe you have democracy now in your beloved Russia, but on this physics bowl team, I rule with an iron fist. (makes fist in the air) Ow!

Sheldon: Gentlemen.
Leonard: Sheldon.
Howard: Sheldon.
Raj: Hee, hee, hee, hee, hee, hee, hee.
Penny: Sheldon.

Leonard: This is our year! With those guys out, the entire physics bowl will kneel before Zod.
Penny: Zod?
Howard: Kryptonian villain. Long story.
Raj: Good story. (clasps hands to mouth in shock)

Leonard: Do I need to quote Spock's dying words to you?
Sheldon: No, don't.
Leonard: The needs of the many...
Howard: Outweigh the needs of the few...
Sheldon: Or the one. Damn it, I'll do it. (does a Vulcan salute)
