1724: Thief Jack Sheppard first arrested. He will be arrested and imprisoned five times in 1724 but escape four times from prison, making him a notorious public figure, and wildly popular with the poorer classes.
1789: Chemist, philosopher, educator, and crime-fighter Joseph Priestley gives landmark sermon on the use of Gnomon algorithm functions in the detection and prevention of crimes against chemistry.
1834: Inventor and crime-fighter Charles Grafton Page correlates transdimensional corporations with crimes against mathematical constants.
1843: Rudolf Clausius publishes new class of Gnomon algorithm functions based on thermodynamics.
1915: Physicist and academic Robert Hofstadter born. He will share the 1961 Nobel Prize in Physics (together with Rudolf Mössbauer) "for his pioneering studies of electron scattering in atomic nuclei and for his consequent discoveries concerning the structure of nucleons".
1958: Transdimensional corporation spontaneously generates four-dimensional bacteriophage, perhaps as a result of the Tybee Bomb event.
1978: An episode of Euglena Junction shocks viewers when the actor playing the role of Uncle Joe is eaten by water fleas.
1988: Mathematician Dorothy Lewis Bernstein dies. She was the first woman to be elected president of the Mathematics Association of America.
2015: Physicist and academic Val Logsdon Fitch dies. He shared the 1980 Nobel Prize in Physics with co-researcher James Cronin for a 1964 experiment which proved that certain subatomic reactions do not adhere to fundamental symmetry principles (CP violation).
2018: Signed first edition of Creature 3 used in high-energy literature experiment unexpectedly generates cryptographic numina after experience a CP violation event of unknown origin.
