"An Original Theory or New Hypothesis of the Universe" by Thomas Wright is a collection of letters to a friend that puts forth an idea about the universe. Using math and observations of nature, the author explains the Milky Way and the overall nature of our visible world. He knows new ideas, especially about space, can be hard for people to accept, yet he wants to look at planets and their movements, blending math with deeper, thoughtful ideas about the universe. The author thinks being curious is key to understanding the universe and that learning about space helps us understand the divine plan of creation.
