When I was younger, I understood these theories much better. Today I read them like a fascinated, but a bit distant bystander.

But it is terribly interesting. What does turning physics into math mean? When we find a mathematical shortcut that works but we don't understand - is this real? What is the relation between mathematical formulas and reality? And will we finally understand gravity some day?

It was an interesting article, but I am not sure I understood it all. I guess, I'm getting old. Or just too specialized.
