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
Hilbert symbol reciprocity law follows from the Artin reciprocity law and the definition of the Hilbert symbol in terms of the Artin symbol. If "K" is a number field containing the "n"th roots of unity, "p" is a prime ideal not dividing "n", π is a prime element of the local field of "p", and "a" is coprime to "p", then the power residue symbol () is related to the Hilbert symbol by The power residue symbol is extended to fractional ideals by multiplicativity, and defined for elements of the number field by putting ()=() where ("b") is the principal ideal generated
