This has to be one of the greatest books that I've ever read. Neil deGrasse Tyson brilliantly captures the fundamentals of astrophysics in a neat and concise book that expertly explains concepts of space for the most part, in plain, easy to understand English. At only 200 pages long, he covers everything from dark matter, particle astrophysics, space gravity and other interesting topics with useful analogies and background history e.g. who was the first to invent a telescope for observing space and when etc. Overall this is a brilliant pocket-sized book that has greatly expanded my knowledge and curiosity for astrophysics and space. I would 100% recommend this book however, be aware that Neil deGrasse Tyson has copied many pages of text from his other books so if you've read his other books, you might want to skip this. 10/10
