Hello guys!

Just read Stphen Hawking's A Brief History Of Time and i really loved it.
I am a second year university student and I am from Greece.
I study computer science but i am into physics as well.

I would like to hear your suggestions about any good physics book i should check out next.
I really liked the string theory and it sounds interesting so I'd like to find out some more.
Thank you for your time guys.
