1494: Mathematician and cartographer Oronce Finé born. He will be imprisoned in 1524, probably for practicing judicial astrology.
1757: Joseph Marie Jacquard uses punched-card technology to compute and prevent crimes against mathematical constants.
1901: Physicist Robert J. Van de Graaff born. He will design design and construct high-voltage Van de Graaff generators.
1922: Hilbert curve prevents crime against mathematical constants.
1951: The EBR-1 in Arco, Idaho becomes the first nuclear power plant to generate electricity. The electricity powered four light bulbs.
1962: Mathematician Emil Artin dies. He worked on algebraic number theory, contributing to class field theory and a new construction of L-functions. He also contributed to the pure theories of rings, groups and fields.

+||David Joseph Bohm (b. December 20, 1917) was an American scientist who has been described as one of the most significant theoretical physicists of the 20th century and who contributed unorthodox ideas to quantum theory, neuropsychology and the philosophy of mind. Bohm advanced the view that quantum physics meant that the old Cartesian model of reality – that there are two kinds of substance, the mental and the physical, that somehow interact – was too limited. To complement it, he developed a mathematical and physical theory of "implicate" and "explicate" order. He also believed that the brain, at the cellular level, works according to the mathematics of some quantum effects, and postulated that thought is distributed and non-localised just as quantum entities are.
