Jennifer's wedding day was fa...

Jennifer's wedding day was fast approaching. Nothing could dampen her excitement - not even her parent's nasty divorce.
Her mother had found the PERFECT dress to wear, and would be the best-dressed mother-of-the-bride ever!
A week later, Jennifer was horrified to learn that her father's new, young wife had bought the exact same dress as her mother!
Jennifer asked her father's new young wife to exchange it, but she refused. "Absolutely not! I look like a million bucks in this dress, and I'm wearing it," she replied.
Jennifer told her mother who graciously said, "Never mind sweetheart. I'll get another dress. After all, it's your special day."
A few days later, they went shopping, and did find another gorgeous dress for her mother.
When they stopped for lunch, Jennifer asked her mother, "Aren't you going to return the other dress? You really don't have another occasion where you could wear it."
Her mother just smiled and replied, "Of course I do, dear... I'm wearing it to the rehearsal dinner the night before the wedding."

Martin Schwarzschild

Born 31 May 1912; died 10 Apr 1997 at age 84.German-American astronomer who worked on stellar structure and evolution, including pulsating stars and differential solar rotation, the helium flash and the ages of star clusters. He traced the post-main sequence evolutionary tracks on the Hertzprung-Russel diagram, indicating how stars become red giants. The computer techniques he used to make stellar models were taken up by subsequent astrophysicists. In 1957, he initiated the Stratoscope projects, using hot-air balloons to carry scientific and photographic instruments to unprescedented stratospheric heights. Using that stable platform he obtained, high-resolution observations of the turbulence in the photosphere of the sun, free from ground-based atmospheric effects. His is the son of German astrophysicist Karl Schwarzschild. In 1936, Martin fled the Nazi regime and moved to America.«
