James Bond

In The Property of a Lady from Octopussy (the earlier editions of the three-part short story book included this story), James Bond (a character created by Ian Fleming) attended an auction to identify a top KGB spy. This spy was to raise the value of a Fabergé egg so that his female double agent working in MI5 (The British Secret Service) would get more money (as a way to monetarily pay her back for many years of service) from the sale of her (previously sent from Russia) Fabergé egg. The lot number of the Fabergé egg was 42.

Asteroid Douglasadams

In January 2005, Asteroid 2001 DA42 was given the name Asteroid Douglasadams, named for the author Douglas Adams who popularized the number 42 and died in 2001. With even his initials in the provisional designation, Brian G. Marsden, the director of the Minor Planet Center and the secretary for the naming committee, said, “This was sort of made for him, wasn’t it?”

Bach

42 was one of J.S. Bach’s (the composer) favourite numbers. He worked this out by adding up the numbers of position of the letter BACH in the alphabet and then multiplying the answer by three (from the holy trinity). E.G.:

B + A + C + H
2 + 1 + 3 + 8 = 14 * 3 = 42

Journey to the center of the earth, and beyond

In 1965, mathematician Paul Cooper theorized that the fastest, most efficient way to travel across continents would be to bore a straight hollow tube directly through the Earth, connecting a set of antipodes, evacuate it (remove the air), and then just fall through. The first half of the journey consists of free-fall acceleration, while the second half consists of an exactly equal deceleration. The time for such a journey works out to be 42 minutes. Remarkably, even if the tube does not pass through the exact center of the Earth, the time for a journey powered entirely by gravity always works out to be 42 minutes, as long as the tube remains friction-free, as while gravity’s force would be lessened, so would the distance traveled at an equal rate. The same idea was proposed by Lewis Carroll in Sylvie and Bruno, volume 2, chapter 7, without calculation.
