Saving Life

A college physics professor was explaining a particularly complicated concept to his class when a pre-med student interrupted him.
"Why do we have to learn this stuff?" The young man blurted out.
"To save lives," the professor responded before continuing the lecture.
A few minutes later the student spoke up again. "So how does physics save lives?"
The professor stared at the student for a long time. "Physics saves lives," he said, "because it keeps the idiots out of medical school."

James Prescott Joule

Born 24 Dec 1818; died 11 Oct 1889 at age 70. English physicist who established that the various forms of energy - mechanical, electrical, and heat - are basically the same and can be changed, one into another. Thus he formed the basis of the law of conservation of energy, the first law of thermodynamics. He discovered (1840) the relationship between electric current, resistance, and the amount of heat produced. In 1849 he devised the kinetic theory of gases, and a year later announced the mechanical equivalent of heat. Later, with William Thomson (Lord Kelvin), he discovered the Joule-Thomson effect. The SI unit of energy or work , the joule (symbol J), is named after him. It is defined as the work done when a force of 1 newton moves a distance of 1 metre in the direction of the force.
