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."

Sir Joseph Whitworth

Died 22 Jan 1887 at age 83 (born 21 Dec 1803).English mechanical engineer (Baronet), who pioneered precision measurement. He held many patents for machine tools, textile and knitting machinery, and road-sweeping machines. He originated a scraping technique to make a true plane surface (1825). He advocated using the decimal system. In 1841, his standard screw threads were adopted by the Woolwich Arsenal. By 1851 Whitworth's machine tools were internationally known for their accuracy and quality, as well as his screw cutting lathes, his planing, drilling, slotting, and shaping machines, and his millionth-part measuring machine. He also did pioneering work in ordnance, creating a method for casting ductile steel to replace hard steel, which is subject to fracture.«
