Or is it just a useful construct that does not satisfy E = mc², and in fact doesn't fit into any real equation?

And what early physics teachers tell you, that potential energy "turns" into kinetic energy and so forth, is just another confusing and inappropriately informal misrepresentation?

Where's the rigor in potential energy? Does it have a differential equation? Can it even really be measured, or just deduced?

What other "types" of energy are actually kinetic energy?

Animal X lives in a forest with very tall trees. While he can survive the best fruit grows at the top of the tree. Over time his descendants have long necks well evolve long necks. I can accept its not chance the long necked ones survive and take over short necked. But the fact the neck grew in the first place has to be chance unless the animal genome is intelligent and can pass down to the next one has to have a longer neck.
Mutated genes fair enough but is the mutation not down to chance. If there was a long necked mutation surely there could have been other mutations what a stroke of luck to evole the correct mutation where in fossil record are mutations that went wrong in my example we start off with only short necked animals long necked ones come along later. Lets say it takes millions of years for the long necked version to be perfected if the mutation is chance would there not be evidence of the mutations that went wrong

All they need is the power for the flux capacitor (which is powered by plutonium) I don't see what the forward velocity does?

I know that in the equation, there are a couple pf n's...
The equation is P=(nRT/v-nb)-(n^2-a/V^2)

I know that the first n, the one from nRT is equal to the number of moles, but what about the other n's o.0 what do they equal....

Thank you in advance

Can an experimental physicist support a family? What is the job market for the profession? Starting from a non-physics major (industrial engineering) how long would it take to get to the field, assuming full-time studying?

Advice is highly appreciated,
Thanks!
