Hi!
I will appreciate if anyone can tell me the physical interpretation or at least the importance of the Navier-Stokes ladder theorem, but without getting into mathematical technicalities.
Capacitors and dielectrics pertain electric phenomena, one could say that inductors can be considered analogues of capacitors in the magnetic case. Is there a dielectric analogue in magnetism?...

Some thermodynamics confusion. Assume ideal gases for simplicity. Are kinetic energy (K) and internal energy (U) for gases, different from one another? As I understand, dU = n Cv dt And if some...

I have encountered some ambiguity regarding the applicability of Newton's third law of action-reaction to the force of gravitation. For two masses m1 and m2, separated by a distance r, the law of...

1) Do vacuum and empty space imply the same? Can they be used interchangeably? 2) If a sealed "empty" box resting on a table is slided to another position, is the space if "encapsulated", also...

Isn't special theory of relativity an offshoot of a measurement problem, though of different kind than from quantum mechanics? If a watch is designed whose measure of time does not depend on light...
