TYCHO BRAHE, THE DANISH ASTRONOMER who made comprehensive astronomical measurements of the solar system and whose data were used by his assistant, Johannes Kepler, to formulate his (Kepler) laws of planetary motion, lost his nose in a duel with one of his students over a mathematical computation.
Scholar Noel Botham in his book The Book of Useless Information (New York, NY: Penguin Group [USA] Inc., 2006) reports that Brahe wore a silver replacement nose for the rest of his life.
