These were not errors that detracted from the overall ability to understand the material, and there were only a few throughout the whole of the book. There is a section on gravity where the Moon's acceleration around the Earth is compared to the acceleration on the surface of the Earth, and a number for the acceleration of the Moon is stated as known, without context.

But other knowledge, including advanced math and the rational thought, were used as the skills needed to allow modern western culture to expand The only topic from my previous book that was not covered as much in this one was the possible ends of the universe (Heat Death, etc.). The coverage of basic physics is less than in some of the other introductory textbooks, but again seems to be adequate for this level. The content presented in the book is accurate and error-free. I would suggest stating a series of facts about the Moon that tell the reader how someone in the 17th century already knew the centripetal acceleration of the Moon due to the Earth (parallax for Moon distance, velocity based on circumference and time to go through zodiac, etc.) This voluminous book covers all the areas of introductory Astronomy in detail and it is usually taught in most universities and colleges over two semesters.
