Sir Isaac NewtonDied 20 Mar 1727 at age 84 (born 25 Dec 1642). English physicist and mathematician who made seminal discoveries in several areas of science, and was the leading scientist of his era. His study of optics included using a prism to show white light could be split into a spectrum of colours. The statement of his three laws of motion are fundamental in the study of mechanics. He was the first to describe the moon as falling (in a circle around the earth) under the same influence of gravity as a falling apple, embodied in his law of universal gravitation. As a mathematician, he devised infinitesimal calculus to make the calculations needed in his studies, which he published in Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy, 1687).«
Fresh out of business school, the young man answered a want ad for an accountant. Now, he was being interviewed by a very nervous man who ran a small business that he had started himself.
"I need someone with an accounting degree," the man said. "But mainly, I'm looking for someone to do my worrying for me."
"Excuse me?" the accountant said.
"I worry about a lot of things," the man said. "But I don't want to have to worry about money. Your job will be to take all the money worries off my back."
"I see," the accountant said. "And how much does the job pay?"
"I'll start you at eighty thousand."
"Eighty thousand dollars!" the accountant exclaimed. "How can such a small business afford a sum like that?"
"That," the owner said, "is your first worry."
