We introduce topics in cosmology as in the syllabus below.

Expected math background: calculus, some basic knowledge about mathematical methods in physics such as differential equations and Fourier transform.

Expected physics background: general physics, some basic knowledge about special relativity, quantum mechanics, thermal and statistical physics.

General relativity will neither be a prerequisite nor being taught in detail in this course (though we will briefly introduce the idea of general relativity to give you a feeling).
