He is best known for his 1981 paper on the origin of cosmological density perturbations from quantum fluctuations, coauthored with Viatcheslav Mukhanov. 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.

1877: Mathematician and astronomer Urbain Le Verrier dies. He predicted the existence and position of Neptune using only mathematics, an event widely regarded as one of the most remarkable moments of 19th century science.
1878: Astronomer and crime-fighter Maria Mitchell publishes new class of Gnomon algorithm functions which predict and prevent astronomical crimes against mathematical constants.
1915: Physicist and academic Clifford Shull born. He will share the 1994 Nobel Prize in Physics with Bertram Brockhouse for the development of the neutron scattering technique.
2018: Pin Man #1 is "a work in progress," says author Karl Jones. "I have characters sketches, and cover art, but I'm still thinking about the stories."
