A golfer, who was known for hi...

A golfer, who was known for his bad temper, walked into the Pro Shop one day and plunked down big bucks for a new set of woods.
The staff all watched to see what would happen after he used them for the first time - more than half expecting he'd come in and demand his money back.
But the next time he came in, he was all smiles.
"They're the best clubs I've ever had," he said. "In fact, I've discovered I can throw them at least 40 yards farther than I could my last ones."

Baron Jean-Baptiste-Joseph Fourier

Died 16 May 1830 at age 62 (born 21 Mar 1768). French mathematician, Egyptologist and administrator who exerted strong influence on mathematical physics through his Théorie analytique de la chaleur (1822; The Analytical Theory of Heat). He introduced an infinite mathematical series to aid in solving conduction equations. This analysis technique allows the function of any variable to be expanded into a series of sines of multiples of the variable, which is now known as the Fourier series. His equations spawned many new areas of study in mathematics and physics, including the branch of optics named for him, have subsequently been applied other natural phenomena such as tides, weather and sunspots.
