Though my soul may set in darkness, it will rise in perfect light;
I have loved the stars too fondly to be fearful of the night.
These are the last lines of a poem called “The Old Astronomer and His Pupil” by Sarah Williams. It is a tribute to the great astronomer Tycho Brahe. He was a dashing figure who lost his nose in a duel against a fellow Danish nobleman over a mathematical formula. His assistant, Johannes Kepler, would later steal Brahe’s huge body of celestial measurements to come up with the three laws of planetary motion.
