Dining Companion

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, "No he didn't. He just walked in the door."

Polykarp Kusch

Died 20 Mar 1993 at age 82 (born 26 Jan 1911). German-American physicist who shared the Nobel Prize for Physics in 1955 for his accurate determination that the magnetic moment of the electron is greater than its theoretical value. This he deduced from researching the hyperfine structure of the energy levels in certain elements, and in 1947 found a discrepancy of about 0.1% between the observed value and that predicted by theory. Although minute, this anomaly was of great significance and led to revised theories about the interactions of electrons with electromagnetic radiation, now known as quantum electrodynamics. (He shared the prize with Willis E. Lamb, Jr. who performed independent but related experiments at Columbia University on the hyperfine structure of the hydrogen atom.)
