Disappearing diner

A man and a beautiful woman were having dinner in a fine restaurant. Their waitress, taking another order at a table a few paces away suddenly noticed that the man was slowing sliding down his chair and under the table, but the woman acted unconcerned. The waitress watched as the man slid all the way down his chair and out of sight under the table. Still, the woman dining across from him appeared calm and unruffled, apparently unaware that her dining companion had disappeared.

After the waitress finished taking the order, she came over to the table and said to the woman, "Pardon me, ma'am, but I think your husband just slid under the table." The woman calmly looked up at her and replied firmly, "No he didn't. My husband just walked in the door."

Jacobus Cornelius Kapteyn

Born 19 Jan 1851; died 18 Jun 1922 at age 71.Dutch astronomer who used photography and statistical methods in determining the motions and spatial distribution of stars. Such work was the first major step after the works of William and John Herschel. He tried to solve the questions of space density of stars as a function of distance from the sun, and the distribution of starts according to brightness per unit volume. Some of his results had lasting value, but some were superceded because he had failed to account for the interstellar absorption. In studies using proper motion to determine stellar distances, he discovered stellar motions are not random, as previously thought, but that stars move in two "star streams" (1904). He introduced absolute magnitude and colour index as standard concepts.
