Graduate Special Relativity breaks down in matter?
Thanks.But this is a review and not to introduce any new idea. Above three papers are important although they were not collected by arxiv0710.0461. For example, the speed of a neutrino is unnecessary to be c which is useful to understand the newest report of CERN (arXiv:1109.4897v1). The...- Mr.GaGa

Graduate Special Relativity breaks down in matter?
Special Relativity breaks down in matter? The same idea was proposed by several authors( Ravndal arXiv:0810.1872v1, Crenshaw arXiv:0812.3348v2 , Wang arXiv:0909.1856v2, et al ) to study Abraham-Minkowski controversy (http://en.wikipedia.org/wiki/Abraham%E2%80%93Minkowski_controversy). They...- Mr.GaGa

High School Whether the speed of alternative/direct current is faster than light?
I read http://en.wikipedia.org/wiki/Drift_velocity and the velocity of charge(electron) is very slow. Actually, it is the electromagnetic fiel in conductors to transimit energy and signal whose velocity is much faster than light in vacuum. In particular, it is infinity according to the...- Mr.GaGa

High School Whether the speed of alternative/direct current is faster than light?
Why the value is 66-99% c ? Would you like to give some references to show the result?- Mr.GaGa

High School Whether the speed of alternative/direct current is faster than light?
Whether the speed of alternative/direct current is faster than light? What's the speed of alternative and direct current in metals? c, less or greater? It is impossible to be c because metal is not vacuum.- Mr.GaGa

High School Faster than the speed of light
An example to exceed c has been proposed. A recent paper is to prove the velocity of motion V in point mechanics should be the energy flow velocity S/w (S_Poynting vector,w_energy density) of the wave theory instead of the group velocity and so on. This velocity(V or S/w) of surface...- Mr.GaGa
