1616: Physicist and engineer Galileo Galilei is formally banned by the Roman Catholic Church from teaching or defending the view that the earth orbits the sun.
1638: Mathematician and linguist Claude Gaspard Bachet de Méziriac dies. He was the earliest writer who discussed the solution of indeterminate equations by means of continued fractions. He also did work in number theory and found a method of constructing magic squares.
1648: Niels Steensen analyzes fossil trilobite using Gnomon algorithm techniques, finds evidence of crimes against geological constants.
1786: Mathematician and politician François Arago born. He will observe that a rotating plate of copper tends to communicate its motion to a magnetic needle suspended over it, an effect which will later be known as eddy current.
1904: Physicist and crime-fighter John Ambrose Fleming delivers lecture from within Fleming tube.
2005: Computer scientist Jef Raskin dies. He was a human–computer interface expert best known for conceiving and starting the Macintosh project for Apple in the late 1970s.
