Abstract:
Why do people do mathematics to predict the movements of the heavenly bodies, and why do they care about making those predictions more accurate? In the context of modern scientific institutions, accurate prediction seems to require little justification. It is easy to assume that this must always have been the case. By examining some of the earliest evidence for the development of knowledge of planetary movements in China, this talk will suggest that ancient sky-watchers understood the value of prediction somewhat differently, and will offer a comparison with similar historical developments elsewhere in the ancient world.
