comment Using Relaxation Method to Model Negative Dielectrics in an electric field?
Thanks thought it was a long shot but it was something I wanted to know and I thought it would help the site grow.

comment Is quantum entanglement mediated by an interaction?
What about his incorrect assumption "According to EPR experiments measurements of the entangled states are at odds with SR"?

comment What is the difference between a measurement and any other interaction in quantum mechanics?
Reading about Rydberg Atoms may help you understand how different quantum states are produced experimentally. In order to produce a quantum state that has a probability function that is diffuse spatially or in terms of energy it is often necessary to limit it's interaction to the outside world to a large degree. The measurement is preformed between these diffuse states and some probe which is produced to have a well defined quantum states.

comment How do 2 magnets spin by themselves if positioned precisely?
@Jonathan - No, because the magnets produce a force on each other. By positioning the magnets from S-N S-N to S-N N-S you have done work on the system by over coming the magnetic field and put the system into a state of high potential energy. That potential energy is then converted to kinetic energy in the movement you saw and will eventually be dissipated by friction just like Vortico said.
