Willem de Sitter

Died 20 Nov 1934 at age 62 (born 6 May 1872). Dutch mathematician, astronomer, and cosmologist who developed theoretical models of the universe based on Albert Einstein's general theory of relativity. He worked extensively on the motions of the satellites of Jupiter, determining their masses and orbits from decades of observations. He redetermined the fundamental constants of astronomy and determined the variation of the rotation of the earth. He also performed statistical studies of the distribution and motions of stars, but today he is best known for his contributions to cosmology. His 1917 solution to Albert Einstein's field equations showed that a near-empty universe would expand. Later, he and Einstein found an expanding universe solution without space curvature.

The brunette gets some extra gardening done, the redhead goes to a bar, and the blonde goes home to find her husband having sex with the female boss! She quietly sneaks out of the house and returns at her normal time. "That was fun," says the brunette. "We should do it again sometime." "No way," says the blonde. "I almost got caught!"
