... lies close to the charge neutrality point for every node. For simplicity, we assume that the Weyl nodes are locally isotropic to reduce the number of effective parameters. It is likely straightforward, though tedious, to generalize and study anisotropic systems. We will firstly review the hydrodynam ...

... Miletus, a Greek living in around 600 B.C., observed that when a piece of amber was rubbed, the amber attracted bits of straw. However it was not until 2500 years later that the forces between charged particles were actually measured by Coulomb using a torsion balance method. The details of Coulomb' ...

Anti-gravity

Anti-gravity is an idea of creating a place or object that is free from the force of gravity. It does not refer to the lack of weight under gravity experienced in free fall or orbit, or to balancing the force of gravity with some other force, such as electromagnetism or aerodynamic lift. Anti-gravity is a recurring concept in science fiction, particularly in the context of spacecraft propulsion. An early example is the gravity blocking substance ""Cavorite"" in H. G. Wells' The First Men in the Moon.In Newton's law of universal gravitation, gravity was an external force transmitted by unknown means. In the 20th century, Newton's model was replaced by general relativity where gravity is not a force but the result of the geometry of spacetime. Under general relativity, anti-gravity is impossible except under contrived circumstances. Quantum physicists have postulated the existence of gravitons, a set of massless elementary particles that transmit the force, and the possibility of creating or destroying these is unclear.""Anti-gravity"" is often used colloquially to refer to devices that look as if they reverse gravity even though they operate through other means, such as lifters, which fly in the air by using electromagnetic fields.
