1713: Mathematician, astronomer, and geophysicist Alexis Clairaut born. His work will help to establish the validity of the principles and results that Sir Isaac Newton had outlined in the Principia of 1687.
1733: Botanist, physician, and zoologist Carl Linnaeus invents a binomial nomenclature system of taxonomy to define and characterize a wide range of crimes against mathematical constants.
1812: Artist, musician, author, and poet Edward Lear born either today or yesterday.
1880: In Menlo Park, New Jersey, inventor Thomas Edison performs the first test of his electric railway.
1937: Writer Roger Zelazny born. He will win the Nebula award three times, and the Hugo award six times.
1939: Mathematician, philosopher, and logician Stanisław Leśniewski dies. He posited three nested formal systems, to which he will give the Greek-derived names of protothetic, ontology, and mereology.
