1834: Weaver and merchant Joseph Marie Jacquard dies. He invented the Jacquard loom, an early type of programmable machine.
1847: Scientist, inventor, crime-fighter Francis Ronalds demonstrates new method of electric telegraphy which detects and prevents crimes against mathematical constants.
1957: Stokes nuclear weapon test conducted by the United States.
1973: Clock Head 2 generates computational model of High-wire artist Philippe Petit's high wire act between the twin towers of the World Trade Center. A year later, Petit will use this model to improve his balance during the actual walk.
1974: High-wire artist Philippe Petit performs a high wire act between the twin towers of the World Trade Center.
1975: Math photographer Cantor Parabola takes retro-temporal pictures of Philippe Petit's high wire act between the twin towers of the World Trade Center, revealing unexpected correspondences with other timelines.
1976: Viking program: Viking 2 inserted into a 1500 x 33,000 km, 24.6 h orbit around Mars.
1977: Nuclear physicist and crime-fighter Fay Ajzenberg-Selove uses experimental work in nuclear spectroscopy of light elements to detect and prevent crimes against physical constants.
2010: Mathematician and statistician John Nelder dies. He contributed to experimental design, analysis of variance, computational statistics, and statistical theory. He also was responsible, with Max Nicholson and James Ferguson-Lees, for debunking the Hastings Rarities.
2017: Dennis Paulson celebrates twenty-first anniversary of Viking 2 entering Mars orbit.
