comment Where do magnets get the energy to repel?
What is you D ? The electric displacement field ? ( Note: I agree that you can associate a potential to certain magnetic fields, but your clearly wrote "magnetic field is conservative" ...)

OK, but what if you actually displace the magnets while they are repelling each other ?

comment Where do magnets get the energy to repel?
Magnetic field is conservative ? That absolutely WRONG ... A field is conservative if its rot F = 0, then you can have a potential defined as F = - grad P. rot H = m0 J , so ... In addition I think there is a confusion between that and the concept of state variable, as you said "history".

What theories are you talking about ? You should be more specific.

comment Lay explanation of the special theory of relativity?
Good that you separate the principles from the most common "conclusions" as a lot of people mix both.

comment Lay explanation of the special theory of relativity?
The problem is : after the beta we will have a lot of questions like that, it is unrealistic to answer individually each one of them. The best answer to this one is "Look in Wikipedia, then ask more specific questions".

"To the extend of my knowledge we don't how to tune up mass." : just by taking another particle

comment Hamilton's Principle
It should be noted that this is "Hamilton's principle", that is is not exactly the same as "Hamiltonian [classical] mechanics" (ie, where an actual Hamiltonian is involved) and that is as nothing specific about QM.
