There's two in particular that I've seen over and over, Fabric of the Cosmos and The Elegant Universe, both by Dr Brian Greene (I think I've butchered his name). I think things are slowly starting to sink in for me, very slowly, but the actual mathematics behind it still just looks like a scary wall of characters to me.
It's all just so fascinating! When you see our place in the universe, some of the silly worries kinda disappear I find.
haha, I've often been tempted to say the same thing to people to the east of us! Australian's man, they're so far ahead of us!
