A Text-Book of Astronomy

"A Text-Book of Astronomy" by George C. (George Cary) Comstock is an education resource from the early 1900s that dives into the core ideas and measurement skills required to understand astronomy, covering everything from how things move in space to different cosmic events. Instead of just explaining facts, the book wants students and teachers to get involved by making observations for themselves. Starting off, it explains that it's more about teaching a method for learning about space than listing every detail that's known. It stresses how important it is to take good measurements in astronomy, and introduces simple steps for seeing and noting things in the sky. Early chapters also cover basics like how to measure angles and time, which are must-knows for anyone wanting to study stars and planets. The book sets a hands-on tone for understanding the universe.
