The Course Outline: Cosmology I, Fall 1401 (Fall 2022) Cosmology is the science of the universe as a whole A study of cosmology brings smallest scales, relevant to quantum mechanics and particle physics, in contact with the largest scales, scales as big as the size of the universe Many progresses on the theoretical sides
In some senses, we are at the golden age of cosmology This course is devoted to theoretical cosmology at the PhD level There are numerous textbooks on this subject, many of them written by leading researchers of this eld In this course we will mainly follow the excellent textbook by Steven Weinberg: \Cosmology", Oxford University Press, 2008
a selection of recommended cosmology books, at the popular, intermediate, and advanced levels Many people (too many to name individually) helped in the making of this book; I thank them all I owe particular thanks to the students who took my undergraduate cosmology course at Ohio State University Their
