Course Description
Celestial mechanics has attracted the interest of some of the greatest mathematical minds in history, from the ancient Greeks to the present day, and has motivated many significant mathematical developments. We shall discuss some outstanding problems and approaches to them, from the Kepler’s problem (describing the motion of a planet around a star), the famous 3body problem (e.g. the motions of the sun, the earth and the moon), to the more general nbody problem.

Honesty in Academic Work
The Chinese University of Hong Kong places very high importance on honesty in academic work submitted by students, and adopts a policy of zero tolerance on cheating and plagiarism. Any related offence will lead to disciplinary action including termination of studies at the University. Although cases of cheating or plagiarism are rare at the University, everyone should make himself / herself familiar with the content of the following website:
http://www.cuhk.edu.hk/policy/academichonesty/and thereby help avoid any practice that would not be acceptable.
