I knew almost nothing about Astrophysics but I was really interested to learn more. I picked up this book because of two reasons, it's only 200 pages long and the author is Neil degrasse Tyson, who is known for simplifying scientific concepts. I also loved his show "Cosmos: A Spacetime Odyssey". Of course since the book is short some details are overlooked so I had to constantly be assisted by Google. Nevertheless, I learned a LOT and my interest in Astrophysics grew even more and I think this book gave me a base on which I'd further build my knowledge. Overall, I truly enjoyed reading it and it's actually the first non-fiction book I've completed. The only downside to this entire book is the last chapter "Reflections on The Cosmic Perspective". It's not a 100% bad but I just didn't like it, I didn't know why it was necessary to add. The cosmic perspective is interesting but I don't find Neil's personal reflections on it as interesting? Idk. All this being said, it's still a good fun book that doesn't feel so dense, so it serves as a great gateway to Astrophysics for beginners.
