Hello, I was just wondering if anyone has used the software Mathematica 7. I heard it's a really good program and with the new functions it looks great, i was just wanted to get some good user feedback from people who definitely know what they're talking about. Thanks! P.S. - as a side note, has anyone used the book 'Six Ideas That Shape Physics: C, E, N, Q, R, T' by Thomas A. Moore? I'm using this text for my physics course this fall and haven't heard of it before.
