# List of mathematics references

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

## Season 1

### "Love's Labours Lost in Space" (1ACV04)

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

## Season 2

### "Xmas Story" (2ACV04)

### "The Lesser of Two Evils" (2ACV06)

- Flexo's and Bender's serial numbers, 3370318 and 2716057 respectively, are a sum of two cubes(this is 100% a reference):

- 3370318 = 119
^{3}+ 119^{3} - 2716057 = 952
^{3}+ (-951)^{3}

### "Put Your Head on My Shoulders" (2ACV07)

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

### "Raging Bender" (2ACV08)

- This episode as well as in "I Dated a Robot", features the theater Loew's ℵ
_{0}-Plex. 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's theater. (it represents the cardinality, not the size).

### "The Problem with Popplers" (2ACV15)

- On the billboard that Leela again crashes, it shows how much Popplers were sold. It says: 3.8 x 10
^{10}popplers sold. That number is the average distance from the Earth to the Moon (measured in centimetres).

### "The Honking" (2ACV18)

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

## Season 3

### "Parasites Lost" (3ACV02)

- 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.

### "Insane in the Mainframe" (3ACV11)

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

### "Future Stock" (3ACV21)

- π
^{th}Avenue is an irrational avenue, one of the many irrational references by the Futurama writers!

## Season 4

### "Less than Hero" (4ACV04)

- πkea is yet another irrational number reference.

## Season 5

*Bender's Big Score*

- 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.

*The Beast with a Billion Backs*

- 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."

*Bender's Game*

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

## Season 6

### "Rebirth" (6ACV01)

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

### "Lrrreconcilable Ndndifferences" (6ACV11)

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

### "Benderama" (6ACV17)

- Prof. Farnsworth 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 Banach-Tarski. 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*."

## Recurring

### "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. Or, time has been recalibrated in the future).

## Comics

### "The Bender You Say"

- There is a game show asking "What's the last digit of π?", and the man answers 7. But π is an irrational number, 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 "if
*p*then*q*" is vacuously true if*p*is false.
