Thanks to the Encyclopedia Britannica thingy on my Yahoo home page, it came to be known that today is Tycho Brahe's birthday, 14 December, 1546. That would make him ............well, really old. (http://en.wikipedia.org/wiki/Tycho_Brahe)
The chain of events that led to the overthrow of the Ptolemaic, Earth centered universe, has always fascinated me. Kepler (http://en.wikipedia.org/wiki/Kepler) and Brahe pretty much started the revolution. Continued by Copernicus (http://en.wikipedia.org/wiki/Copernicus) and Galileo (http://en.wikipedia.org/wiki/Galileo), and others. And, now we know that not even Sol is the center.
And Brahe might very well be the most interesting of them all. A Danish nobleman ( my wife is half Danish so that gives him a good head start in my book), Brahe noted the great differences in astronomical measurements at the time. He constructed several observatories, 1500's, pretelescope, style, to try to get more accurate and precise values. He and his assitant, Kepler, noted that things did not seem as they should and that the only way to make them work out was to make the sun the center. Brahe was more the measurer and Kepler the geometrician.
As a student at the University of Copehagen, he got into an enebriated rapier fight (Brahe was enebriated, not the rapier) and got his nose pretty much cut off. “For the rest of his life, he was said to have worn a replacement made of silver and gold blended into a flesh tone, and used an adhesive balm to keep it attached.” (Wikipedia) Tycho for a period of time had a clairvoyant dwarf and a pet moose. But the poor moose drank too much beer and fell down the stairs and died. The dwarf just stayed under Brahe's table.
Tycho had a good relationship with King Frederick II but disagreed with the new King Christian IV and he and Kepler moved to Poland. He probably died of mercury poisoning. Since he was also a chemist (alchemist), he messed around with mercury salts. But also should have known better. Rumors that Kepler poisoned him (possible but doubtful) and took all his data and equipment (which he did). In physics classes in 2007, we learn Kepler's laws. Not Brahe's Laws.
They don't make Danes the way they used to.
