This course provides an overview of the basic physical picture as well as historical accounts
of classic and modern cosmology. Cosmology has been one of the central interest of human
beings. Ancient people had a very different picture of the universe than we have now. Since
then, our picture of the universe has evolved tremendously as our understanding of physics
has advanced, while at early times religious reasons were also necessary to develop
cosmological models. Recently, cosmology has entered a new era with precision observations,
which reveal new cosmological puzzles that will probably lead us to discover new physics.
The lectures will cover cosmological models, expansion of the universe, redshifts, the early universe,
cosmic inflation, dark matter and energy, special and general relativity, as well as stars, galaxies,
quasars and black holes.

Class & Help Sessions
Homework & Exams
- Class meets at WEL 3.502 on MWF 9-10.
- Help sessions will be scheduled for help with the homework and exams.
- Location: RLM 15.216B; Time: 5-6pm
- There will be 5 homework assignments. These will be written assignments and reports. All written assignments
must be in computer-generated format - no hand written work. Some of the assignments may involve problem-solving
- Homework assignments will not be counted after the due date. Homework can be done in groups
(and I encourage this) but you must hand in your own work. Homeworks that are duplicates will have severe penalties.
You may get help on homework (or anything else) from the professor or TA during office hours, help sessions, or
- The midterm and final will consist of multiple choices. The penalty for cheating on an exam is a score of zero for
the exam, and the zero will be included to calculate the final grade.
