  • 1470: Mapmaker Martin Waldseemüller born. He will produce a globular world map and a large 12-panel world wall map using the information from Columbus and Vespucci's travels (Universalis Cosmographia), both bearing the first use of the name "America".

  • 1798: Mineralogist, physicist, and mathematician Franz Ernst Neumann born. His 1831 study on the specific heats of compounds will include what is now known as Neumann's Law: the molecular heat of a compound is equal to the sum of the atomic heats of its constituents.

  • 1831: Mathematician Carl Jacobi appointed professor. After a four hour disputation in Latin, Jacobi was appointed professor at the University of Konigsberg. While there he inaugurated what was then a complete novelty in mathematics: research seminars for the more advanced students and interested colleagues.

  • 2013: Mathematician and computer scientist Andrzej Trybulec dies. He developed the Mizar system: a formal language for writing mathematical definitions and proofs, a proof assistant which is able to mechanically check proofs written in this language, and a library of formalized mathematics which can be used in the proof of new theorems.
