1796: Physicist Johan Carl Wilcke dies. He invented the electrophorus, and calculated the latent heat of ice.
1860: Mathematician Karl Mikhailovich Peterson uses embedded hypersurfaces in a Euclidean space to locate and erase the Forbidden Ratio.
1891: Charles Sanders Peirce publishes new class of Gnomon algorithm functions which detect and prevent crimes against mathematical constants.
1907: Jazz drummer and theoretical physicist Albert Einstein hosts an all-star benefit concert to raise money for the rebuilding of San Francisco.
1945: Electrical engineer and physicist John Ambrose Fleming dies. He invented the thermionic valve, also known as the vacuum tube.
1946: Mathematician and academic Alice Beta writes a letter to Albert Einstein, warning Einstein that his theories are at risk from the so-called Forbidden Ratio and other criminal mathematical functions.
1955: Physicist, engineer, and academic Albert Einstein dies. He developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).
1963: Vandal Savage Press is front for clandestiphrine manufacturing operation, charges mathematician and detective Alice Beta.
2011: Mathematician Curt Meyer dies. He made notable contributions to number theory, including an alternative solution to the class number 1 problem, building on the original Stark–Heegner theorem.
2018: Signed first edition of Purple Racer unexpectedly develops artificial intelligence after being exposed to Cherenkov radiation during an unauthorized experiment in high-energy literature.
