Theory of everything?

[NNadir]

5. I briefly looked through "A New Kind of Science" a few years back...

...and it didn't inspire me deeply.

That said, Wolfram Mathematica is a pretty widely used tool and from what I've seen of it - which is not all that much - it seems impressive; although in my son's undergraduate work, they had a semi-serious class on it, but mostly for just number crunching stuff, I'm told they tend to use MatLab.

Of course, people make fun of Matlab: There's an old football rivalry between my son's university and a neighboring university and someone hung a poster from a dorm reading "[Other University] Computer Scientists Program in Matlab!" which was thought to be a great insult.
