Photographer

A photographer for a national magazine was assigned to take pictures of a great forest fire. He was advised that a small plane would be waiting to fly him over the fire.
The photographer arrived at the airstrip just an hour before sundown. Sure enough, a small Cessna airplane was waiting. He jumped in with his equipment and shouted, "Let's go!" The tense man sitting in the pilot's seat swung the plane into the wind and soon they were in the air, though flying erratically.
"Fly over the north side of the fire," said the photographer, "And make several low-level passes."
"Why?" asked the nervous pilot.
"Because I'm going to take pictures!" yelled the photographer. "I'm a photographer, and photographers take pictures!"
The pilot replied, "You mean you're not the flight instructor?"

Alfred Wolf

Died 17 Dec 1998 at age 75 (born 13 Feb 1923).Alfred Peter Wolf was an American nuclear and organic chemist. As a senior chemist at the U.S. Brookhaven National Laboratory, he made pioneering contributions over nearly 50 years in the field of organic radiochemistry. By the mid-1960's, his fundamental studies in the synthesis of small, radiolabeled compounds grew into a new interest in developing radiotracers labeled with short-lived positron emitting isotopes like carbon-11 so that the tracer method could be applied to visualize biochemical transformations in living systems. His discoveries led to advances in medical imaging, especially the development of positron emission tomography, or PET, a tool now used worldwide to diagnose disease and study the brain's inner workings.
