That sounds amazing. Assuming enough people submitted often enough, it would be the best screensaver ever. If there were enough users for it to be real-time it would be even cooler. On Nov 2, 5:43 pm, Jason Grout wrote: > On 11/2/10 7:22 PM, William Stein wrote: > > > > > > > > > > > On Tue, Nov

Cellular automata of the sort that Wolfram talks about can be implemented in languages other than Mathematica much more efficiently. Maybe 10,000 times faster when I wrote some stuff in lisp. Not for doing anything useful, just a speed competition. Their importance in Mathematica per se is proba

Yes, I have read it (at least a part of it, it's huge). I agree with you, none of his hypotheses are supported by any evidence; they're just assumptions. Agreed too on the lack of modesty, too. It's the most self-indulgent piece of scientific literature I've ever read. However, it does have many in

Thank you. I will definitely try to build upon that source. However, it seems to be outdated; it gives tracebacks when run. What I meant was, what is necessary for it to be implemented into the main Sage distribution, once it is written? Or is it too niche to be added? Thanks. -- To post to thi
