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."

Computing scale

In 1900, the first automatic computing scale was issued a patent to the Toledo, Ohio, inventor Allen De Vilbiss, Jr. After applying for the patent on 24 Jan 1899, he formed the De Vilbiss cale Co., predecessor of the Toledo Scale Co. This company produced a number of firsts in innovations for scales. In addition to the first automatic computing pendulum-type scale, other firsts included an indicator controller to bring the hand to a quick stop, a cylinder type platform scale, automatic-dial portable scale and auto truck scales using a shallow pit.
