@layman,
Quote:And wrong. The theory must come first. It is of paramount important, not it's mathematical consequences.
This is an interesting philosophical question... but a theory that doesn't can't be tested by experiment and shown to be mathematically valid is not scientifically valid.
You are claiming that the concept of potential energy is "logically inconsistent" even though this concept is accepted, and used, by scientists and engineers. You are saying this is "logically inconsistent" because it doesn't make sense to you. And yet, the educated hard working people who actually do real science don't agree with you.
The great thing about science is that when two people disagree -- in this case you and real scientists, there is a clear, unambiguous way to show who is correct and who is wrong.
You set up the question in mathematical terms. You design an experiment making predictions based on your hypothesis. You run the experiment taking careful record. You then publish the experiment, along with your mathematical reasoning for other scientists to check for correctness. Then you decide if the results support your hypothesis or not (and if it doesn't, you drop it).
The great thing about mathematics is that there is a clear, objective, definition of rightness and wrongness.
The reason I believe in potential energy as a valid scientific concept is because
1) I have studied and I understand the math (an integral path through a force field).
2) Not only do I understand the experiments that support the concept, I have actual performed them myself (I can't say this about QM experiments).
3) I have seen the concepts based on potential energy (from electrodynamics and thermodynamics) and see their usefulness and their experimental validity.
There is a very strong argument in favor of potential energy (as a matter of fact, people who have taken a single college course in Physics know it as fact).
Yet you reject it because it doesn't make sense to you. Let's see if you have an alternative explanation.... Potential Energy explains and predicts what happens when an object falls in gravity... or a ball rolls down a low-friction ramp. Do you have an alternative to potential energy that can do this?
