’’The Age of Newton’’ is an intensive course in mathematics (calculus), mechanics, optics, and astronomy directed mainly toward nonscientists. Although it introduces the subjects in a consciously historical context, it is a course in—not merely about—science and mathematics. The course is divided into a central lecture series, at which guest lecturers may participate, a series of topical tutorial lectures, and four workshops or laboratories, one each in mathematics, mechanics, optics, and astronomy. Original sources, notably Newtons’sOpticsand Galileo’sTwoNewSciences, are used as far as practicable. Special apparatus was built to allow the performance of the experiments described by Newton and Galileo, in addition to modern experiments with air tracks, spectroscopes, lasers, and the rotating room.
