Proposition Infinity the method used for "Proposition Infinity", as the team felt that most viewers would not have a strong opinion for or against robot and human intermarriage, thus lightening the potentially polarizing nature of the source material. "Proposition Infinity" was inspired by the political battle over California Proposition 8 in the United States and heavily satirizes the controversy over same-sex marriage. The title is a reference to California Proposition 8 with the "8" sideways, thus becoming the symbol of infinity (∞). The camp where Bender is being reprogrammed parodies conversion therapy camps for homosexuals. The episode also satirizes the people against
Kronecker symbol Kronecker symbol In number theory, the Kronecker symbol, written as formula_1 or formula_2, is a generalization of the Jacobi symbol to all integers formula_3. It was introduced by . Let formula_3 be a non-zero integer, with prime factorization where formula_6 is a unit (i.e., formula_7), and the formula_8 are primes. Let formula_9 be an integer. The Kronecker symbol formula_10 is defined by For odd formula_8, the number formula_13 is simply the usual Legendre symbol. This leaves the case when formula_14. We define formula_15 by Since it extends the Jacobi symbol, the quantity formula_17 is simply formula_18 when formula_19. When formula_20,
