Tycho Brahe and the Measure of the Heavens

Tycho Brahe and the Measure of the Heavens, by John Robert Christianson

What an interesting man. Invented modern astronomy but still never worked out that Copernicus was right. (Tycho favoured a model where everything else orbits the sun, but they all orbit the Earth.) As well as being an observational scientist he was a very laissez faire (hence, best) kind of Christian, even believing in a form of astrology that didn’t impact human free will. And on top of all that, you come to realise what a fascinating powerhouse of ideas Europe was at the time (we were just plodding through the Elizabethan age), with scientists and philosophers sharing ideas freely across national borders … as well as having the plague, religious wars etc.
