1665: Mathematician Pierre de Fermat dies. He is recognized for his discovery of an original method of finding the greatest and the smallest ordinates of curved lines, which is analogous to that of differential calculus, then unknown.
1665: The San Pietro scrying engine spontaneously generates an elegy for Pierre de Fermat.
1875: Children reprogram Jacquard loom to perform scrying engine functions.
1876: Author Jack London born. He will become one of the first fiction writers to obtain worldwide celebrity and a large fortune from his fiction alone.
1909: Mathematician and academic Hermann Minkowski dies. He showed that Albert Einstein's special theory of relativity can be understood geometrically as a theory of four-dimensional space–time, since known as the "Minkowski spacetime".
2005: Deep Impact launches from Cape Canaveral on a Delta II rocket. It will be the first spacecraft to eject material from a comet's surface.
