Kepler meets Brahe
On February 4, 1600, Johannes Kepler arrived in Prague to begin his collaboration with Tycho Brahe. Kepler provided mathematical calculation skills to make sense of the wealth of data that Brahe had accumulated as an enthusiastic and accomplished astronomical observer. Brahe gave Kepler the task of determining a way to reliably compute the orbit of Mars. What Kepler had initially thought would take eight weeks to accomplish, actually extended to eight years work. Brahe died abruptly on October 24, 1601, having bequeathed his data, records and instruments to Kepler who also was appointed his successor as imperial mathematician to the Holy Roman Emperor and Archduke of Austria, Rudolf II.
