Electrical phenomena are a somewhat arbitrary division of electromagnetic phenomena. Some examples are: Atmospheric electricity; Biefeld–Brown effect — Thought by the person who coined the name, Thomas Townsend Brown, to be an anti-gravity effect, it is generally attributed to electrohydrodynamics (EHD) or sometimes electro-fluid-dynamics ...

Electrical phenomena are commonplace and unusual events that can be observed which illuminate the principles of the physics of electricity and are explained by them. Electrical phenomena are a somewhat arbitrary subset of phenomena of electromagnetism in general.
Triboelectric effect (electrical phenomena) (electricity) Trickle-down economics; Trickle-down fashion; Trickle-up economics; Trickle-up fashion; Twisted nematic field effect (display technology) (liquid crystal displays) (liquid crystals) Twomey effect (air pollution) (atmospheric radiation) (clouds, fog and precipitation)
This is a list of art movements in alphabetical order. These terms, helpful for curricula or anthologies , evolved over time to group artists who are often loosely related. Some of these movements were defined by the members themselves, while other terms emerged decades or centuries after the periods in question.
1665 – Francesco Maria Grimaldi highlights the phenomenon of diffraction; 1673 – Ignace Pardies provides a wave explanation for refraction of light; 1675 – Robert Boyle discovers that electric attraction and repulsion can act across a vacuum and do not depend upon the air as a medium. Adds resin to the known list of "electrics".
Africa's many diverse countries are sources of vibrant design with African design influences visible in historical and contemporary art and culture around the world. The study of African design is still limited, particularly from the viewpoint of Africans, and the opportunity to expand its current definition by exploring African visual ...
Kirlian photograph of two coins. Kirlian photography is a collection of photographic techniques used to capture the phenomenon of electrical coronal discharges.It is named after Soviet scientist Semyon Kirlian, who, in 1939, accidentally discovered that if an object on a photographic plate is connected to a high-voltage source, an image is produced on the photographic plate.
