Three doctors

Three doctors are waiting in line to get into the Pearly Gates. St. Peter walks out and asks the first one, "What have you done to enter Heaven?"

"I am a pediatrician and have brought thousands of the Lord's babies into the world."

"Good enough to enter the gates," replied St. Peter and in he goes. The same question is asked of the second doctor.

"I am a general practioner and go to Third World countries three times a year to cure the poor." St. Peter is impressed and allows him through the gates. The third doctor steps up in line and knowing the question, blurts out, "I am a director of an HMO."

St. Peter meditates on this for a while and then says, "Fine, you can enter Heaven...but only for 2 days."

First U.S. Nobel physicist

In 1907, the first U.S. scientist to receive the Nobel Prize was Albert Michelson, a German-born American physicist who received the Nobel Prize for Physics “for his optical precision instruments and the spectroscopic and metrological investigations.” He designed the highly accurate Michelson interferometer and used it to accurately measure the speed of light and establish it as a fundamental constant. In 1887, with Edward Morley, he also used it in an attempt to measure the velocity of the earth through the ether (yielding null results that later led Albert Einstein to his theory of relativity). He measured the standard meter bar in Paris to be 1,553,163.5 wavelengths of the red cadmium line (1892-3).«
