8.286 The Early Universe

8.286 The Early Universe (Fall 2013, MIT OCW). Instructor: Professor Alan Guth. The Early Universe provides an introduction to modern cosmology. The first part of the course deals with the classical cosmology, and later part with modern particle physics and its recent impact on cosmology. (from ocw.mit.edu)

Lecture 11 - Non-Euclidean Spaces: Closed Universes

In this lecture, the professor reviewed Euclid's Postulates and talked about non-Euclidean geometry and a sphere in 4 Euclidean dimensions.
