"The physical universe and it’s laws have little to do with human interaction."

And the models and simultaions we have constructd in our minds have little to do with the real universe that surrounds. But that is all we have to work with, isn't it?

Consider the imaginary physicist I brought up in my example. He is fighting to advance his career in the backstabbing world of academia, dealing with rivals and superiors, departmental rules and professional standards and customs. At the same time, his kid's in trouble with the law, he has to keep him out of jail and figure out how to straighten him out and salvage what's left of his life. Meanwhile, he's got an outside woman, his marriage is in trouble, and his personal and emotional life is in turmoil. And in the middle of all this, his Volvo loses it on an icy patch of road and he has to drop everything to regain control and get out of the way of oncoming traffic.

All these scenarios are imposed on his world of forces and fields, particles and waves. But they are just as real and just as vital to him. But none would matter if he weren't there, he has created these universes, he has imposed those realities on top of the fundamental scaffolding provided by earth, air, fire and water. A knowledge of physics and an expertise in the methods of physicists does him no good at all in navigating these personal realities, these personal universes. The point is that even though they are only an issue because of the way they affect him, he must still deal with them. He is lost in the world of his own dreams and they are deadly.
