Science

  • The atomic number of molybdenum.
  • The angle rounded to whole degrees for which a rainbow appears (the critical angle).
  • In 1966, 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 (also known as Gravity train) 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, without calculation by Lewis Carroll in 1893 in Sylvie and Bruno Concluded.)

Famous quotes containing the word science:

    “We would be a lot safer if the Government would take its money out of science and put it into astrology and the reading of palms.... Only in superstition is there hope. If you want to become a friend of civilization, then become an enemy of the truth and a fanatic for harmless balderdash.”
    —Kurt Vonnegut, Jr. (b. 1922)

    “He has been described as “an innkeeper who hated his guests, a philosopher, and poet who left no written record of his thought, a despiser of women who gave all he had to one, an aristocrat, a proletarian, a pagan, an arcadian, an atheist, a lover of beauty, and, inadvertently, the stepfather of domestic science in America.””
    —Administration in the State of Colo, U.S. public relief program (1935-1943)

    “The negative cautions of science are never popular. If the experimentalist would not commit himself, the social philosopher, the preacher, and the pedagogue tried the harder to give a short- cut answer.”
    —Margaret Mead (1901–1978)
