The Jodcast is a monthly podcast created by astronomers at Jodrell Bank Centre for Astrophysics (JBCA), University of Manchester in Manchester, England. It debuted in January 2006, aiming to inspire and inform the public about astronomy and related sciences, to excite young people with the latest astronomy research results, to motivate students to pursue careers in science, and to dispel ...
Chain fountain. The chain fountain phenomenon, also known as the self-siphoning beads, Mould effect, or Newton beads is a physical phenomenon observed with a chain placed inside a jar. One end of the chain is pulled from the jar and is allowed to fall under the influence of gravity. This process establishes a self-sustaining flow of the chain ...
Katie Mack. Katherine J. Mack (born 1 May 1981) [3] is a theoretical cosmologist who holds the Hawking Chair in Cosmology and Science Communication at the Perimeter Institute. Her academic research investigates dark matter, vacuum decay, and the Epoch of Reionization. [4][1][5] Mack is also a popular science communicator who participates in ...
The main Lovell telescope was rotated to face the onlooking crowd and used as a huge projection screen showing various animated planetary effects. During the interval the 'screen' was used to show a history of Lovell's work and Jodrell Bank. [74] There is an astronomy podcast from the observatory, named The Jodcast. [75]
Author Frank White, who in the 1980s coined the term overview effect after interviewing many astronauts, said that the overview effect is "beyond words", requiring experience to understand, even likening it in this regard to Zen Buddhism. [9] He said that astronauts' very first views of the planet were generally very significant, adding that ...
A former Pentagon official testified to Congress that the U.S. government has evidence that "we are not alone in the cosmos," but that a "cabal" of officials is hiding the information.
Troxler's fading, also called Troxler fading or the Troxler effect, is an optical illusion affecting visual perception. When one fixates on a particular point for even a short period of time, an unchanging stimulus away from the fixation point will fade away and disappear. Research suggests that at least some portion of the perceptual phenomena ...
The Faraday effect causes a polarization rotation which is proportional to the projection of the magnetic field along the direction of the light propagation. Formally, it is a special case of gyroelectromagnetism obtained when the dielectric permittivity tensor is diagonal. [2] This effect occurs in most optically transparent dielectric ...
