What is a magnetic field? by David Sligar
... I've seen one book that stated nickel56 is really at the top of the binding energy curve. It is interesting that many meteorites are made of ferromagnetic elements, iron and nickel, blown out by stars that went supernova! Iron and nickel, with their tightly bound nucleus, seem to give virtual photon ...

Concepts in Theoretical Physics
... Why do the quarks stick together in this way? It s because the quarks are the only particles to feel the strong nuclear force. To understand this better, we next need to look at the forces. ...

Vacuum superconductivity, conventional
... In a simplified picture, an electron in a metal behaves as an almost free negatively charged particle which moves in a background of a lattice of positively charged ions. A conventional superconductivity is a result of condensation of specific “Cooper pairs” made of some of these electrons. Each Coo ...

Quantum vacuum thruster
A quantum vacuum plasma thruster (or Q-thruster) is a proposed type of spacecraft thruster that would work in part by acting on the virtual particles produced by quantum vacuum fluctuations. This was proposed as a possible model for an engine that could produce thrust without carrying its own propellant. Some physicists working with microwave resonant cavity thrusters think that they might be the first examples of such an engine.
