Yup. Can't do geology w/o the geophysics. Actually all of science is sorta one discipline but I don't think anybody can "know it all." Guess that's why we'll be replaced by computers one day.

I remember an old movie about a giant computer that decided to take over because humans had demonstrated that they were unable to run the world. Often wonder....

But I'm just depressed because it is my birthday and I'm getting OLD.
Cheers!
