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?"

Joseph Liouville

Born 24 Mar 1809; died 8 Sep 1882 at age 73.French mathematician who discovered transcendental numbers (those which are not the roots of algebraic equations having rational coefficients), and that there are infinitely many of them. He also did work in real and complex analysis, number theory, and differential geometry. His name is remembered in the Sturm-Liouville theory of differential equations that generalises Joseph Fourier's ideas, and are important in mathematical physics. He studied celestial mechanics. Liouville founded in 1836, and editted for nearly four decades, the Journal de Mathématique which remains a leading French mathematical publication. He editted and published (1843) the manuscripts left behind upon the untimely death of Evariste Galois 22 years earlier.«
