This sort of thing is always interesting to me. I love how by using the analemma and the equation of time you can figure out the times of sunrise/sunset anywhere on the planet for any time of the year [1]. Another interesting thing to read about is the problem of longitude, it's amazing how clever we've had to be to solve such problems in practice. In Florence there is a Galileo museum which showcases some of his ideas on how to compute longitude, namely by using the orbits of Jupiter's moons as a sort of universal clock to make the calculation possible.
