This is the earliest of a number of calculations addressing the origin of density fluctuations in inflationary cosmology, which is the most common hypothesis for the origin of the expanding universe and the structure within it.

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.
