frustrations, frustrations...

I bought a book by Stephen Hawking. A Brief History of Time (latest edition) was on sale and I've been wanting to buy it since highschool! Now at chapter 3 I positively feel abysmal and stupid. But this should be good. The last time I felt stupid was on my fourth year in college, those piles of articles/books written and inspired by sad and dead old people for my Philosophy courses. But then some of those readings were translated from foreign languages, which was proably the reason I found them difficult to understand. Most of those dead authors were French, and God knows how awful people translate that language into English. This time, Hawking is positively clear on language. It's just that I don't understand the concepts very clearly, especially space-time. I mean I understand the illustrations but I can't seem to imagine it in the real world!!! And, gulay, this is already a physics book for lay people. Frustrations, frustrations.
