A Brief History Of Time: Journal Entry 1

Chapter 1 (Pg 1-14) Today, I began my book A Brief History of Time by Stephan Hawking. He talked about the earth’s shape and why it’s round and not flat by using information from a book written by Aristotle. I got to read about the theories on where the solar system was centered around, Isaac Newton’s theory on Gravity and how it affects the universe, and whether not the universe had a beginning or if the universe had just already existed. It included work from famous people like Galileo Galilee, Isaac Newton, Johann Kepler, & Aristotle. I read about the history of theories, arguments, & theses about whether the universe had a beginning or if it was already there. Then Stephan Hawking was talking about what makes a good theory by using Newton’s theory of gravity and Einstein’s theory of relativity as examples. I also read about a time in 1929 when Edward Hubble comes up with the theory of the Big Bang. I also read about relativity & quantum mechanics and how there is yet to be a combination of the two theories (the quantum theory of gravity). And that “our goal, of desiring knowledge, is nothing less than the description of the universe that we live in.
