List of mathematics references

This article attempts to list references to specific and common mathematical issues.


 * The Nimbus ship has the serial number "BP-1729", a reference to the - number, the smallest non-trivial.


 * Bender is his mom's 1729th son, another reference to the Hardy-Ramanujan number.


 * Flexo's and Bender's serial numbers, 3370318 and 2716057 respectively, are a sum of two cubes:
 * 3370318 = 1193 + 1193
 * 2716057 = 9523 + (-951)3


 * While Fry and Amy are in the closet, there are two books labelled P and NP. This refers to the in.
 * Outside of Bender's computer dating service, the sign advertises that it is "discreet and discrete", referencing the field of.


 * This episode as well as in "I Dated a Robot", features the theater Loew's ℵ0-Plex. {w|Aleph number|ℵ (aleph)} is used in a sequence of numbers to represent the size of infinite sets. Also, the suffix -plex means how many screens in a cinema. In this case, the ℵ would indicate that there is a countably infinite number of screens in Loew theater. (it represents the cardinality, not the size).


 * On the billboard that Leela again crashes, it shows how much Popplers were sold. It says: 3.8 x 1010 popplers sold. That number is the average distance from the Earth to the Moon (measured in centimetres).


 * Bender sees the number 1010011010 in the mirror. After the digits have been decoded, it reads "666".


 * In this episode, a sign reads Historic √66 (pronounced Historic Root 66, or Route) is a parody of the U.S. Route 66. It is also an irrational root.


 * The π-in-1 oil is an oil lubricant, with an irrational amount of oils in one.


 * πth Avenue is an irrational evenue, one of the many irrational references by the Futurama writers.


 * πkea is yet another irrational number reference.


 * In Bender's Big Score, Al Gore drives a cab that has the number 87,539,319 on it. This is the third taxicab number.
 * Sweet Clyde demonstrates some razzle-dazzle Globetrotter calculus using variation of parameters and expanding the Wronskian, both techniques used to solve differential equations.


 * In The Beast with a Billion Backs, Colleen can be seen wearing a shirt with a quantified statement at the church where Yivo is introduced. The statement reads "For all X, I Love (heart) X."


 * In the beginning of Bender's Game, the Planet Express ship goes through various numbers, that are the digits of . The number e, as π, is irrational and has infinite digits.


 * Bender visits Studio 1²2¹3³, equal to 54, which is a reference to in New York.


 * The ⁴√4 in Channel ⁴√4 is an irrational number, equal to √2.


 * invents a copy machine that makes 2 exact duplicates of any object. The model on the copier (that looks like an old overhead projector) says . From Wikipedia The Banach–Tarski paradox is a theorem in set-theoretic geometry, which states the following: Given a solid ball in 3‑dimensional space, there exists a decomposition of the ball into a finite number of disjoint subsets, which can then be put back together in a different way to yield two identical copies of the original ball."

"Channel √2 News"

 * While talking of irrational numbers, the √2 in Channel √2 News an irrational number itself, which means (possibly) that there are root signs on remote controls, and more irrational channels out there.

"7¹¹"

 * 7¹¹, equal to 1,977,326,743, is a convenience store open 28 hours a day (possibly 7:00 AM until 11:00 AM of the following day).

"The Bender You Say"

 * There is a game show aksing "What's the last digit of π?", and the man answers 7. But π is an, which means it doesn't end. He would be right if the statement "If there is a last digit of π, then it is 7" were true, and wrong if the statement "There is a last digit of π, and it is not 7" were true. In logic, the statement is  if p is false.
