Elegant Universe


The Wheel is Forever
Has anyone watched this?

It does an awesome job of explaining modern physics that's very easy to understand (and with a lot of special effects). Has anyone else watched it?

I have some issues with String Theory, but the program is extremely well done.

Yeah, our physics lecturer showed it to us in first year. I found it very interesting, and most concepts were easy enough to understand and well-illustrated. I didn't know it was available online, might watch some parts again now :)

I actually had the entire series downloaded onto my HDD last year. Unfortunately the disk crashed before I was halfway through it. It did a good job of simplifying the concepts involved.

Pretty much. It hasn't made a single prediction that has not been made by existing theories. When asked to make a prediction, they give scenarios so far beyond our current technological capabilities, that proof is doubtful to ever come by. If you don't make predictions that can be tested, it's not a valid theory.

It certainly could be true, and the math is extremely elegant. In fact, I'd say it's probably very true, but it's still a hypothesis, not a theory. I don't have a PhD in math, and even I could come up with elegant looking equations that tie things together, but that doesn't mean they have a basis in reality. Math is deductive, most of science is inductive. You can come up with equations using deduction, but then they have to match the data, and if they don't, your deduction is based on faulty assumptions, and you must go back.

Not implying String Theory is like that, but until it makes testable predictions, a lot of intellectual horsepower might be going to waste (all new Theoretical Physics PhD's pretty much focus on it these days).
