What is Cosmology? 

This is the very first of the videos in my new series of Cosmology. I'm going through Dr. Barbara Ryden's textbook "Introduction to Cosmology". If you follow along, you'll get a full upper-division undergraduate course in Cosmology. I used this textbook at William Paterson University.
This course will cover the current state of the science of Cosmology. To follow along, it'll be a good idea for you to ge to know your calculus. Here are the topics of this video:
Introductory Cosmology: Chapter 01. What is Cosmology?
What is Cosmology?
Units of Distance
Units of Mass
Units of Time
Units of Energy and Power
The Very Small
Fundamental Constants of Nature
Planck Units
Gemetrized Units
The Briefest History of Cosmology
How did the Universe begin? Why are we here? When will it all end? What’s it made out of? What’s it’s fate? What’s the meaning of it all? How can we learn anything about any of these questions?
