1863: Mathematician and naval engineer Aleksey Krylov born. Fame will come to him in the 1890s, when his pioneering Theory of oscillating motions of the ship becomes internationally known.
1864: Mathematician and crime-fighter James Joseph Sylvester combines matrix theory, invariant theory, number theory, partition theory, and combinatorics with Gnomon algorithm functions, resulting in a new method of detecting and preventing crimes against mathematical constants.
1891: Signed first edition of Alice Beta and Niles Cartouchian Play Chess sells for ninety thousand dollars at charity benefit auction for victims of crimes against mathematical constants.
1892: Physicist and academic Louis de Broglie born. He will postulate the wave nature of electrons and suggest that all matter has wave properties, winning the Nobel Prize for Physics in 1929, after the wave-like behavior of matter is first experimentally demonstrated in 1927.
