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 ...
The International Environmental Design Contest (IEDC) is a competition hosted by the WERC Consortium and The Institute for Energy & The Environment at New Mexico State University. [1] It is an annual event in which student teams prepare written, oral, poster, and bench-scale model presentations in response to design tasks.
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.
Since then there have been several proposals for Grand Unified Theories, e.g. the Pati–Salam model, although none is currently universally accepted. A major problem for experimental tests of such theories is the energy scale involved, which is well beyond the reach of current accelerators .
Army vet and USA Today reporter Davis Winkie credited killed pilot Rebecca Lobach as instrumental in helping him navigate the "hardest periods" of his personal life during their time together in ...
In particle physics, the Georgi–Glashow model [1] is a particular Grand Unified Theory (GUT) proposed by Howard Georgi and Sheldon Glashow in 1974. In this model, the Standard Model gauge groups SU(3) × SU(2) × U(1) are combined into a single simple gauge group SU(5) .
9. RB Terrell Davis. In what was arguably the greatest Super Bowl effort by a tailback, he ran for 157 yards and a record-tying three TDs – while combating a migraine – on his way to Super ...
Contests have also been run on various other Wikimedia projects, generally eliciting excitement and support; the Wikinews writing contest in March/April and the second German writing contest (part of the International writing contest) both attracted over 10 unusual prizes from the community to hand out to the lucky/skillful winners.
