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.
1703: Mathematician and scientist Vincenzo Viviani dies. In 1660, Viviani and Giovanni Alfonso Borelli conducted an experiment to determine the speed of sound. Timing the difference between the seeing the flash and hearing the sound of a cannon shot at a distance, they calculated a value of 350 meters per second (m/s), considerably better than the previous value of 478 m/s obtained by Pierre Gassendi.
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.
2012: Mathematician, author, activist, and academic Irving Adler dies. He was a plaintiff in the McCarthy-era case Adler vs. Board of Education.
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.
