Looming is a term found in the study of perception, as it relates directly to psychology.Looming occurs when an object begins moving closer to the eye. As the resulting image becomes increasingly larger on the perceiver's retina, i.e., when an object looms, there is an automatic physiological response to perceive the object as an approaching object or surface, instead of one that is stationary ...
Looming of the Canadian coast as seen from Rochester, New York, on April 16, 1871. Looming is the most noticeable and most often observed of these refraction phenomena. It is an abnormally large refraction of the object that increases the apparent elevation of the distant objects and sometimes allows an observer to see objects that are located below the horizon under normal conditions.
There are two primary debris fields: the ring of objects in GSO and the cloud of objects in low Earth orbit (LEO). The Kessler syndrome, also known as the Kessler effect, [1] [2] collisional cascading, or ablation cascade, is a scenario proposed by NASA scientists Donald J. Kessler and Burton G. Cour-Palais in 1978.
A strong time dilation effect has been reported for perception of objects that were looming, but not of those retreating, from the viewer, suggesting that the expanding discs — which mimic an approaching object — elicit self-referential processes which act to signal the presence of a possible danger. [91]
There is a specific acuity limit in detecting an approaching object's looming motion. [ 40 ] [ 41 ] This is regarded as the subtended angular velocity detection threshold (SAVT) limit of visual acuity. [ 42 ]
Object presentation is the way in which objects appear and is a factor that determines the occurrence of change blindness. Change blindness can occur even without a delay between the original image and the altered image, but only if the change in the image forces the viewer to redefine the objects in the image. [ 45 ]
The Jacquard loom is a mechanical loom, invented by Joseph Marie Jacquard in 1801, which simplifies the process of manufacturing figured textiles with complex patterns such as brocade, damask, and matelasse. [26] [27] The loom is controlled by punched cards with punched holes, each row of which corresponds to one row of the design. Multiple ...
A safety pin. Aichmophobia (/ ˌ eɪ k m ə ˈ f oʊ b i ə /) is a kind of specific phobia, the morbid fear of sharp things, [1] such as triangles, stars, squares, pencils, needles, knives, darts, prickly plants (like thistles and similar weeds), cactus trees, pine needles, broken glass, broken porcelain, sharp pieces of wood, a pointing finger, hexagons, or even the sharp end of an umbrella ...
