In the first article on history of astronomy, I provide a brief overview of history of astronomy from ancient time to the time of Johannes Kepler and Galileo Galilei. In the other two articles on history of astronomy, I provide a brief overview of history of astronomy from the time of Sir Isaac Newton to the present. Physics was essentially applied to and received feedback from astronomy during the time period treated in these two articles. Those of you who are not really interested in astronomy may still want to read some parts of these three articles on history of astronomy, because they also treat some interesting concepts and developments in physics, such as Newton’s explanations of Kepler’s laws, Einstein’s general relativity, and Verlinde gravity, which I didn’t explain in details in “A short introduction to the history of physics and string theory as a “Theory of Everything.”” In the last article, I provide some evidences that the Earth is round, as it is alarming that the Flat Earth proponents are gaining momentum these days. They are idiots who reject scientific evidences. They don’t deserve to enjoy modern scientific innovations.
