Pareidolia is a type of apophenia. Common examples include perceived images of ...
A sailing stone in Racetrack Playa. Sailing stones (also called sliding rocks, walking rocks, rolling stones, and moving rocks) are part of the geological phenomenon in which rocks move and inscribe long tracks along a smooth valley floor without animal intervention. The movement of the rocks occurs when large, thin sheets of ice floating on an ...
The Hessdalen lights appear both by day and by night, and seem to float through and above the valley. They are usually bright white, yellow or red and can appear above and below the horizon. The duration of the phenomenon may be a few seconds to well over an hour. Sometimes the lights move with enormous speed; at other times they seem to sway ...
A geological phenomenon is a phenomenon which is explained by or sheds light on the science of geology. Examples of geological phenomena are: Mineralogic phenomena; Lithologic phenomena Rock types. Igneous rock. Igneous formation processes; Sedimentary rock. Sedimentary formation processes (sedimentation) Quicksand; Metamorphic rock; Endogenic ...
The following criteria are required to classify an event as an inattentional blindness episode: 1) the observer must fail to notice a visual object or event, 2) the object or event must be fully visible, 3) observers must be able to readily identify the object if they are consciously perceiving it, [3] and 4) the event must be unexpected and the failure to see the object or event must be due ...
Hutton's Unconformity. Hutton's Unconformity is a name given to various notable geological sites in Scotland identified by the 18th-century Scottish geologist James Hutton as places where the junction between two types of rock formations can be seen. This geological phenomenon marks the location where rock formations created at different times ...
The Swedish Army, who released the picture, was less certain. Ghost rockets (Swedish: Spökraketer, also called Scandinavian ghost rockets) were rocket - or missile -shaped unidentified flying objects sighted in 1946, mostly in Sweden and nearby countries like Finland. The first reports of ghost rockets were made on February 26, 1946, by ...
Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically. Natural patterns include symmetries, trees, spirals, meanders, waves, foams, tessellations, cracks and stripes. [1] Early Greek philosophers studied pattern, with Plato ...
