Natural plasmoid produced in the near-Earth magnetotail by magnetic reconnection. A plasmoid is a coherent structure of plasma and magnetic fields.Plasmoids have been proposed to explain natural phenomena such as ball lightning, [1] [2] magnetic bubbles in the magnetosphere, [3] and objects in cometary tails, [4] in the solar wind, [5] [6] solar atmosphere, [7] and in the heliospheric current ...
Winston H. Bostick (March 5, 1916 – January 19, 1991) was an American physicist who discovered plasmoids, plasma focus, and plasma vortex phenomena. He simulated cosmical astrophysics with laboratory plasma experiments, and showed that Hubble expansion can be produced with repulsive mutual induction between neighboring galaxies acting as homopolar generators.
Einstein attempted to create a classical unified field theory, rejecting quantum mechanics. Among other difficulties, this required a new explanation of particles as singularities or solitons instead of field quanta. Later attempts to unify general relativity with other forces incorporate quantum mechanics.
The toroidal ring model, known originally as the Parson magneton or magnetic electron, is a physical model of subatomic particles. It is also known as the plasmoid ring, vortex ring, or helicon ring. This physical model treated electrons and protons as elementary particles, and was first proposed by Alfred Lauck Parson in 1915.
Comparison of the evolution of the universe under Alfvén–Klein cosmology and the Big Bang theory. [1]Plasma cosmology is a non-standard cosmology whose central postulate is that the dynamics of ionized gases and plasmas play important, if not dominant, roles in the physics of the universe at interstellar and intergalactic scales.
Magnetic reconnection is a breakdown of "ideal-magnetohydrodynamics" and so of "Alfvén's theorem" (also called the "frozen-in flux theorem") which applies to large-scale regions of a highly-conducting magnetoplasma, for which the Magnetic Reynolds Number is very large: this makes the convective term in the induction equation dominate in such regions.
In 1984, he began studying plasma phenomena and laboratory fusion devices, performing experimental work on a machine called a dense plasma focus (DPF). NASA's Jet Propulsion Laboratory has funded mainstream as well as alternative approaches to fusion, and between 1994 and 2001 NASA provided a grant to Lawrenceville Plasma Physics, the company of which Lerner was the only employee, to explore ...
In physics, the Pati–Salam model is a Grand Unified Theory (GUT) proposed in 1974 by Abdus Salam and Jogesh Pati. Like other GUTs, its goal is to explain the seeming arbitrariness and complexity of the Standard Model in terms of a simpler, more fundamental theory that unifies what are in the Standard Model disparate particles and forces.
