A century old Astronomy text book is a fascinating thing. It’s amazing to see what was known 100 years ago, and what was still speculation based on very logical application of physics.

As you fall asleep you will learn about how it was believed the sun produces heat, how long it will continue to shine, and about the structure of the solar system.
