This is kind of driving me crazy. I was watching a program on pbs the other night called "The Elegant Universe" (that's a book too, isn't it?)

Anyways, there was a cello piece played in it and I know I've heard it somewhere before but I've never heard the name. I think it might be a piece played in "The Pianist," but I'm not really sure...

Probably, no one will be able to tell me what it is because you only hear a very small portion of it, but if you go to: http://www.pbs.org/wgbh/nova/elegant/program.html

And click on "the potential of strings" (chapter 2) under hour 3 a little bit is played at about 1:25 and in the next chapter I think the end is played at about 2:00, and I think other places in the program it is played in the background as well...Maybe I'm just a little crazy asking about this but I would really like to know what the piece is...
