At the time, the most remote object was quasar OQ172, at z=3.53, found in 1974. [72] From 1964 to 1997, the title of most distant object in the universe were held by a succession of quasars. [79] That list is available at list of quasars. 3C 295: 1960– z=0.461 This is a radio galaxy. This was the remotest object known at time of discovery of ...
Artificial gravity is the creation of an inertial force that mimics the effects of a gravitational force, usually by rotation. [ 1] Artificial gravity, or rotational gravity, is thus the appearance of a centrifugal force in a rotating frame of reference (the transmission of centripetal acceleration via normal force in the non-rotating frame of ...
A Spin refers to the motion of a pen circularly spinning while it is in contact with the hand or other body part. Spins done on the knuckle-side of the fingers are called "Top Spins". There are many versions of the Spin, and the names usually involve the body parts the pen spins on (e.g., in the Thumb Spin, the pen spins on top of the thumb).
v. t. e. Rotation around a fixed axis or axial rotation is a special case of rotational motion around an axis of rotation fixed, stationary, or static in three-dimensional space. This type of motion excludes the possibility of the instantaneous axis of rotation changing its orientation and cannot describe such phenomena as wobbling or precession.
Fidget spinner. A fidget spinner is a toy that consists of a ball bearing in the center of a multi-lobed (typically three-lobed) flat structure made from metal or plastic with metal weights in the lobes, designed to spin around its central axis. Fidget spinners became very prevalent trending toys in 2017. The toy has been promoted as helping ...
The graviton must be a spin-2 boson because the source of gravitation is the stress–energy tensor, a second-order tensor (compared with electromagnetism's spin-1 photon, the source of which is the four-current, a first-order tensor). Additionally, it can be shown that any massless spin-2 field would give rise to a force indistinguishable from ...
Spin (physics) Spin is an intrinsic form of angular momentum carried by elementary particles, and thus by composite particles such as hadrons, atomic nuclei, and atoms. [ 1][ 2]: 183 –184 Spin is quantized, and accurate models for the interaction with spin require relativistic quantum mechanics or quantum field theory .
Articulate! is a board game from Drumond Park, for 4 to 20+ players aged 12 and up with original concept by Andrew Bryceson. [1] Articulate! players describe words from six different categories (Object, Nature, Random, Person, Action and World) to their team as quickly as possible. The teams move round the board based on the number of words ...
