1770: Physicist and academic Thomas Johann Seebeck born. He will discover the thermoelectric effect.
1805: Mathematician and crime-fighter Joseph-Louis Lagrange delivers lecture on applications of number theory to the detection and prevention of crimes against mathematical constants.
1860: On his phonautograph machine, Édouard-Léon Scott de Martinville makes the oldest known recording of an audible human voice. A visual recording of audio data, it will first be played back in 2008.
1864: Engineer and physicist Wilhelm Röntgen uses X-rays generator to expose loaded dice, reveals organized math crime cartel in casinos around the world.
