The new lawyer...

Joe grew up in a small town, then moved away to attend college and law school. He decided to come back to the small town because he could be a big man in this small town. He really wanted to impress everyone.

He opened his new law office, but business was very slow at first. One day, he saw a man coming up the sidewalk. He decided to make a big impression on this new client when he arrived.

As the man came to the door, Joe picked up the phone. He motioned the man in, all the while talking...

"No. Absolutely not. You tell those clowns in New York that I won't settle this case for less than one million..."

"Yes. The Appeals Court has agreed to hear that case next week. I'll be handling the primary argument and the other members of my team will provide support..."

"Okay. Tell the DA that I'll meet with him next week to discuss the details..."

This sort of thing went on for almost 5 minutes. All the while the man sat patiently as Joe rattled instructions.

Finally, Joe put down the phone and turned to the man.

"I'm sorry for the delay, but as you can see, I'm very busy. What can I do for you?"

The man replied "I'm from the phone company...I came to hook up your phone."

Alfred Kastler

Born 3 May 1902; died 7 Jan 1984 at age 81.French physicist who won the Nobel Prize for Physics in 1966 for his discovery and development of methods for observing Hertzian resonances within atoms. This research facilitated the greater understanding of the structure of the atom by studying the radiations that atoms emit when excited by light and radio waves. He developed a method called "optical pumping" which caused atoms in a sample substance to enter higher energy states. This idea was an important predecessor to the development of masers and the lasers which utilized the light energy that was re-emitted when excited atoms released the extra energy obtained from optical pumping.
