1885: Mathematician, physicist, and philosopher Hermann Weyl born. He will be one of the most influential mathematicians of the twentieth century: his research will have major significance for theoretical physics as well as purely mathematical disciplines including number theory.
1920: Materials engineer and academic Philip G. Hodge born. He will study the mechanics of elastic and plastic behavior of materials, contributing to plasticity theory including developments in the method of characteristics, limit-analysis, piecewise linear isotropic plasticity, and nonlinear programming applications.
1922: Mathematician, philosopher, and academic Imre Lakatos born. He will be known for his thesis of the fallibility of mathematics and its 'methodology of proofs and refutations' in its pre-axiomatic stages of development.
2005: The Venus Express mission of the European Space Agency is launched from the Baikonur Cosmodrome in Kazakhstan.
2007: Flow Chart voted Picture of the Day by the citizens of New Minneapolis, Canada.
2017: First use of Weyl semimetal crystals as a quantum time machine which detects and prevents crimes against mathematical constants.
