e. Quantum entanglement is the phenomenon of a group of particles being generated, interacting, or sharing spatial proximity in such a way that the quantum state of each particle of the group cannot be described independently of the state of the others, including when the particles are separated by a large distance.
Reflective surface to send light back to viewer. (In a backlit LCD, this layer is replaced or complemented with a light source.) A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers.
Maxwell's equations, or Maxwell–Heaviside equations, are a set of coupled partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, electric and magnetic circuits. The equations provide a mathematical model for electric, optical, and radio technologies, such ...
It's easier to manage bills. With a joint account, it's simpler to pay shared expenses like your mortgage, utilities and groceries. You don't have to figure out who owes what or transfer money ...
An article from TCU magazine from 2009 gives a differing account of the origin of the name. It claims the Battle for the Iron Skillet began on Nov. 30, 1946. According to the magazine, the idea of ...
Eigenvalues and eigenvectors. In linear algebra, an eigenvector (/ ˈaɪɡən -/ EYE-gən-) or characteristic vector is a vector that has its direction unchanged by a given linear transformation. More precisely, an eigenvector, , of a linear transformation, , is scaled by a constant factor, , when the linear transformation is applied to it: .
Halley's Comet is the only known short-period comet that is consistently visible to the naked eye from Earth, [ 16 ] appearing every 72–80 years. [ 17 ] It last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061. Officially designated 1P/Halley, it is also commonly called Comet Halley, or sometimes simply ...
9:28: Flight 93 is hijacked above northern Ohio, turning to the southeast. 9:37:46: Flight 77 crashes into the western side of The Pentagon. All 58 passengers and crew are killed aboard the aircraft including an additional 125 (including emergency workers) on the ground. The crash starts a violent fire.
