Museum of the History of Science
The Ashmolean, the world's oldest public museum, was originally housed in this 1683 building, which now holds scientific and mathematical instruments, from astrolabes to quadrants. Among the gems are a wonderful collection of 18th- and 19th-century models of the solar system and the chalkboard Einstein used in a lecture on the Theory of Relativity. There are guided tours on Thursday (2:30 and 3:15) and Saturday (12:30 and 1:15).
