I've always been interested in physics but unfortunately at my school there were basically no classes. So I felt less than informed on the topic and didn't know where to start to learn about it.
A Brief History of Time was certainly a good choice. First of all, Stephen Hawking tries to cover a lot of stuff and explains from the very beginning. Thus, the reader can follow the evolution of physic!
Furthermore, he uses some nice metaphors, to make it easier to grasp. It definitely helped to have a familiar picture that I could connect with the sometimes complicated topics.
Hawking tries hard to make this as understandable is somehow possible, so that we all can get an insight into the history of the universe. He doesn't always succeed and some stuff confused me a bit. But in general A Brief History of Time helped me a lot to learn about physics!
