Despite what ShamelessC says about the skepticism of other physicists, I found Stephen Wolfram's talk absolutely fascinating. For the first time, some disparately related notions in my mind ceased to be so and now make sense to me in that they're integrally related in ways I'd not given much thought to previously.

Irrespective of whether he's on the correct track or not, his explanation of certain phenomena, energy for instance, made complete sense. His way of using analogies to describe abstract processes is superb. By that I mean he is able to present one with conceptually understandable mental pictures or images of difficult physics that one would normally only understand through mathematical equations.

It's a shame more physicists don't take a leaf [or do I mean branch - pun intended ;-)] from his way of presenting these concepts.

Which has received a good deal of skepticism from the scientific community.
