Join astronomer and lecturer Martin Griffiths for a journey to the heart of early modern science on our tour of mediaeval Prague in the footsteps of Tycho Brahe and Johannes Kepler. Johannes Kepler (1571-1630), namesake of the NASA space observatory, was one of the world’s most influential astronomers whose work on optics and the laws of planetary motion would influence the ground-breaking research of Galileo and Newton after him. He spent some of his most important years working with Tycho Brahe in Prague, whom he replaced in 1601 as imperial mathematician and advisor to Holy Roman Emperor Rudolph II. The Prague of the 17th century was a melting pot of international artists, scientists and thinkers, attracted by the tolerant political climate which made their work possible. On our five night tour we shall discover the legacy of Brahe and Kepler, including the world’s oldest Astronomical Clock, Benatky Castle where Kepler conducted some of his early experiments; and an evening visit to the Ŝtefánik Observatory.
