... Planets and most satellites move in elliptical orbits. This motion is caused by gravitational attraction forces. Since these forces act in pairs, the sum of the moments of the forces acting on the system will be zero. This means that angular momentum is conserved. ...

On an Intriguing Invention Albert Einstein Made Which Has Gone
... 8.3. Inventing a System of Units for All Times and All Civilizations In 1865, German physicist Rudolph Clausius, then forty-three-years old, had a preference for letters from the last half of the alphabet to represent entities in his equations—he used the letters M to Z, except O and Y. He selected ...

Condensed matter realization of the axial magnetic effect
... vF becomes smaller simply because it costs less energy to populate states with higher p. The spontaneous generation of angular momentum and an edge current are typical phenomena in parity-violating physics, as occurs, for instance, in the A phase of helium-3 [4] (see also Ref. [47]). Our model adds ...

... Nuclear magnetic resonance, or NMR as it is abbreviated by scientists, is a phenomenon which occurs when the nuclei of certain atoms are immersed in a static magnetic field and exposed to an oscillating electromagnetic field. Some nuclei experience this phenomenon, and others do not, dependent upon ...

Electric and magnetic fields - The Physics of Bruce Harvey
... The primary purpose in nature of magnetic fields is to surround moving elementary charged particles and contain their potential energy. When elementary charged particles move in a co-ordinated way, they generate an extended magnetic field. This is a secondary function of nature. If we are to underst ...

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.
