1618: Johannes Kepler uses Gnomon algorithm functions to prevent crimes against laws of planetary motion.
1878: Chemist and physicist Henri Victor Regnault dies. He was an early thermodynamicist, best known for his careful measurements of the thermal properties of gases, and for mentoring William Thomson in the late 1840s.
1883: Mathematician Alfred Clebsch born. He will make important contributions to algebraic geometry and invariant theory.
1884: Electrical engineer and crime-fighter Zénobe Gramme uses what will later be called the Gramme Device to detect and prevent crimes against mathematical constants.
2015: Engineer and inventor Justin Capră dies. He designed fuel-efficient cars, unconventional engines, aircraft, and jet backpacks.
2016: Army research laboratories convert modern plowshares into ancient swords. Military contractors call technique "Astonishing breakthrough."
