Does Nantenna (nano antenna) violates 2nd Law of Thermodynamics? Yes they do have a cooling effect which is even used in some aquarium tank cooling device. And you are right, they require a temperature difference to produce electricity. |

Show the Lorentz Transformation Matrices Have an Inverse There is typo: 0≠u∈kerΛ. instead of u≠0∈kerΛ |

Why is my speed imaginary? Why don't you just try the conservation of energy. mdvdt=mvdvdR is false. |

How does Sol's magnetic field continue to exist at such high temperatures? Actually, I have just read a paper about Beltegeuse. It is not the rotational dynamics that induces the magnetic field but convection cells. |

Why do grapes in a microwave produce plasma? @Georg: You would be inspired to check your physics. Rotaional spectroscopy is a field in itself. lsbu.ac.uk/water/vibrat.html |

Conservation of Energy in a magnet If it takes the energy from the field, then the field is modified and the continuity equations at the magnet surface implies that the magnet's inside field is also modified. It is either due to the dipolar magnetic field created by the steel ball (that was my initial guess in a question I have asked) or by a magnetic domain reconfiguration (the answer I got). |

On non-local physics It is indeed a very interesting possible explanation. But if you are new to the field of kinetic theory, I suggest you first read: Generalized Boltzmann Physical Kinetics [Hardcover] by Alexeev, Boris V. |

Conservation of Energy in a magnet It does not make any sense. Why does a steel ball attracted by an electromagnet takes its energy from the generator and why does it take it from the field for a permanent magnet !! |

Conservation of Energy in a magnet That's what I have first thought about, but it does not stand when we compare this solution to the electromagnet's solution. Griffith shows the generator provides the extra work. Magnetic force does not work. |
