Private Audience With the Holy Mother

After a long life of unselfish service, Father John O'Malley died and went to heaven. St. Peter met him at the gate and said: "John, you did such a wonderful job for us on earth, we'd like to do something special for you. You name it; it's yours."
John thought for a moment and said: "I'd like a private audience with the Holy Mother." St. Peter told him it would be arranged.On the appointed day, St. Peter escorted John to the Holy Mother's sanctuary. John went before Her, knelt, and said: "Holy Mother, I've always looked to You for guidance, and You have granted me peace and serenity through some difficult times. But I have one question that has nagged me during my whole time on earth. In all the paintings that were done of you, and in all the sculptures that were carved of you, you always looked so sad. Why is that?"
Mary thought for a moment, pursing her lips. She said: "I always wanted a girl."

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.«
