Only 232 years old and doing fine
Today is the anniversary of the birth of Carl Friedrich Gauss in 1777. Although we claim him for the mathematicians, lots of people share in Gauss's legacy. He did pioneering work in celestial mechanics, geodesy, and physics as well as mathematics. Fortunately for many mathematicians (but perhaps not for mathematics), Gauss did not publish all his results, allowing them to get credit for discoveries he had long since made on his own.
By the way, some people insist on writing Gauss's first name as “Karl.” That's the German way, right? Don't be fooled. The man himself favored “Carl” when he signed his name and I render his name as he preferred. The only catch: He wrote his last name as Gauß, of course, but we Anglophones have difficulty following him there.
Happy Gauss's Birthday, everyone!
