Two possible mechanisms give origin to the spin Hall effect, in which an electric current (composed of moving charges) transforms into a spin current (a current of moving spins without charge flow). The original (extrinsic) mechanism devised by Dyakonov and Perel consisted of spin-dependent Mott scattering , where carriers with opposite spin ...
When the rattleback is spun in the "stable direction", also known as the weak reversal direction, friction and damping often slow the rattleback to a stop before the rolling instability has time to fully build. Some rattlebacks, however, exhibit "unstable behavior" when spun in either direction, and incur several successive spin reversals per spin.
This endlessly cool treehouse is a hidden gem nestled in a wooded area in the town of Mendenhall, about 40 minutes outside Jackson. Looking like something akin to a wooden spaceship from a ...
These tops may be thrown forward while firmly grasping the end of the string and pulling it back. The forward momentum of the top contributes to the string's tension and thus to the final spin rate. In some throwing styles, the top is thrown upside-down, but the first loop of the rope is wound around a stubby "head".
Gravitoelectromagnetism, abbreviated GEM, refers to a set of formal analogies between the equations for electromagnetism and relativistic gravitation; specifically: between Maxwell's field equations and an approximation, valid under certain conditions, to the Einstein field equations for general relativity.
Spencer Suderman (born August 17, 1966 in Far Rockaway, New York as Spencer Denenberg) is an American airshow performer, [1] Guinness World Record holder for most inverted flat spins, [2] [3] [4] flight instructor, [5] and aviation video producer. [6]
In architecture, an inverted pyramid is a structure in the shape of an upside-down pyramid. The Hanoi Museum and Hong Kong Coliseum are buildings which have an inverted pyramidal shape. The Pyramide Inversée in Paris is a skylight of this shape. The Tokyo Big Sight's conference tower consists of four inverted pyramids mounted on support bases.
The Louvre Inverted Pyramid (French: Pyramide inversée du Louvre) [1] is a skylight constructed in the Carrousel du Louvre, an underground shopping mall in front of the Louvre Museum in France. It may be thought of as a smaller sibling of the more famous Louvre Pyramid proper, yet turned upside down: its upturned base is easily seen from outside.
