New study sheds light on molecular motion

New research has shown how a synthetic self-made fibers can guide molecular movement that can be fuelled by light over long distances, a discovery that could pave the way for new ways to use light as a source of sustainable ...

First ALMA animation of circling twin young stars

Researchers analyzed the accumulated data from the Atacama Large Millimeter/submillimeter Array (ALMA) and depicted the motion of a young twin star system XZ Tauri over three years. This first-ever "ALMA Animation" of twin ...

A breakthrough in droplet manipulation

Researchers in the Department of Mechanical Engineering at the University of Hong Kong (HKU) have made a key breakthrough in droplet manipulation. They have discovered an innovative way to navigate liquids on a surface in ...

Slow and regular earthquakes interact near Istanbul

Earthquakes typically last only a few seconds, although sometimes the shifts in the subsurface occur in slow motion. Understanding these 'slow quakes', known as 'slow slip events', and their interplay with the short—sometimes ...

Tracking the movement of a single nanoparticle

Based on the principle of interaction between matter and light, a new method has been developed to track and observe the Brownian motion of fast-moving nanometer-sized molecules, and measure the different fluorescence signals ...

Decoding electron dynamics

Electron motion in atoms and molecules is of fundamental importance to many physical, biological and chemical processes. Exploring electron dynamics within atoms and molecules is essential for understanding and manipulating ...

Film

A film, also called a movie or motion picture, is a series of still or moving images. It is produced by recording photographic images with cameras, or by creating images using animation techniques or visual effects. The process of filmmaking has developed into an art form and industry.

Films are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them. Film is considered to be an important art form, a source of popular entertainment and a powerful method for educating – or indoctrinating – citizens. The visual elements of cinema give motion pictures a universal power of communication. Some films have become popular worldwide attractions by using dubbing or subtitles that translate the dialogue into the language of the viewer.

Films are made up of a series of individual images called frames. When these images are shown rapidly in succession, a viewer has the illusion that motion is occurring. The viewer cannot see the flickering between frames due to an effect known as persistence of vision, whereby the eye retains a visual image for a fraction of a second after the source has been removed. Viewers perceive motion due to a psychological effect called beta movement.

The origin of the name "film" comes from the fact that photographic film (also called film stock) has historically been the primary medium for recording and displaying motion pictures. Many other terms exist for an individual motion picture, including picture, picture show, moving picture, photo-play and flick. A common name for film in the United States is movie, while in Europe the term film is preferred. Additional terms for the field in general include the big screen, the silver screen, the cinema and the movies.
