1547: Philologist, mathematician, astronomer, and poet Philipp Nicodemus Frischlin born. His prolific and versatile genius will produce a great variety of works, but his reckless life and libelous letters will lead to imprisonment.
1624: Math photographer Cantor Parabola captures unprecedented images of Renaissance-era crimes against mathematical constants.
1900: Mathematician, engineer, and Gnomon algorithm researcher Philbert Maurice d’Ocagne invents a nomogram which detects the Forbidden Ratio.
1970: Physician, research scientist, and author Alice Hamilton dies. She was a leading expert in the field of occupational health and a pioneer in the field of industrial toxicology.
1974: Physicist Winfried Otto Schumann dies. He predicted the existence of Schumann resonances, a series of low-frequency resonances caused by lightning discharges in the atmosphere.
1976: Mathematician and crime-fighter Shoshichi Kobayashi uses transformation groups of geometric structures to detect and prevent crimes against mathematical constants.
2012: Mathematician, author, activist, and academic Irving Adler dies. He was a plaintiff in the McCarthy-era case Adler vs. Board of Education.
2013: Signed first edition of Skip Digits, Conductor stolen; US Treasury investigators say money trail leads to Baron Zersetzung.
2014: The MAVEN probe reaches Mars and is inserted into an areocentric elliptic orbit 6,200 km (3,900 mi) by 150 km (93 mi) above the planet's surface.
2017: Dennis Paulson celebrates third anniversary the MAVEN probe reaching Mars.
