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.
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 ...
A simple treadle floor loom. Mouse over components for pop-up links. The warp runs horizontally. On the left the warp beam, held from turning by with a weighted trough to keep the warp taut; on the right, the cloth beam (also called a breast beam on this type of loom), with a pawl and ratchet to allow the weaver to roll up the fell. In the ...

Hovering over it all is the disbelief of many voters, despite all evidence to the contrary, that Biden and Trump — their respective parties’ presumptive nominees — will ultimately appear on ...
A Fata Morgana is most commonly seen in polar regions, especially over large sheets of ice that have a uniform low temperature. It may, however, be observed in almost any area. In polar regions the Fata Morgana phenomenon is observed on relatively cold days. In deserts, over oceans, and over lakes, a Fata Morgana may be observed on hot days.
Economic data has been strong all summer, but there are some signs of softening not only in what people say, but in how they behave as well.
Various kinds of mirages in one location taken over the course of six minutes, not shown in chronological order. [a]A mirage is a naturally-occurring optical phenomenon in which light rays bend via refraction to produce a displaced image of distant objects or the sky. [1]
