1851: Physicist and chemist Hans Christian Ørsted dies. He discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism.
1917: Mathematician and philosopher Georg Cantor publishes new theory of sets derived from Gnomon algorithm functions. Colleagues hail it as "a magisterial contribution to science and art of detecting and preventing crimes against mathematical constants."
1928: Engineer Gerald Bull born. He will attempt to build artillery guns capable of launching satellites into orbit.
1941: The Eel Escapes Hydrolab is "proof that The Eel is a criminal," according to Baron Zersetzung.
