Magnetite nanowires with sharp insulating transition

Magnetite (Fe3O4) is best known as a magnetic iron ore, and is the source of lodestone. It also has potential as a high-temperature resistor in electronics. In new research led by Osaka University, published in Nano Letters, ...

Improving heat recycling with the thermodiffusion effect

Absorption heat transformers can effectively reuse the waste heat generated in various industries. In these devices, specialised liquids form thin films as they flow downward due to gravity. These liquid films can absorb ...

Mobile cinemas in China are a lens on society

Mobile cinemas appeared in China in the 1950s as a means for the government to educate people and spread communist messages to the countryside. The roving cinemas ran until the late '80s, but their popularity waned as TV ...

Fusion scientists have developed a 'nano-scale sculpture technique'

A research team of fusion scientists has succeeded in developing a "nano-scale sculpture technique" to fabricate an ultra-thin film by sharpening a tungsten sample with a focused ion beam. This enables the nano-scale observation ...

X-rays reveal monolayer phase in organic semiconductor

A team of researchers from Russia, Germany, and France, featuring materials scientists from the Moscow Institute of Physics and Technology, has investigated how the electrical properties of dihexyl-quarterthiophene thin films ...

Graphenes now go monolayer and single crystalline

IBS-CMCM scientists have reported a truly single layer (i.e., adlayer-free) large area graphene film on large area copper foils. They refined the chemical vapor deposition (CVD) growth method by eliminating all carbon impurities ...

Creating 'movies' of thin film growth

From paint on a wall to tinted car windows, thin films make up a wide variety of materials found in ordinary life. But thin films are also used to build some of today's most important technologies, such as computer chips ...

Film

Film encompasses individual motion pictures, the field of film as an art form, and the motion picture industry. Films are produced by recording images from the world with cameras, or by creating images using animation techniques or special effects.

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 gives motion pictures a universal power of communication. Some films have become popular worldwide attractions by using dubbing or subtitles that translate the dialogue.

Traditional 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) had historically been the primary medium for recording and displaying motion pictures. Many other terms exist for an individual motion picture, including picture, picture show, photo-play, flick. A common name for film in the United States is movie, while the Europeans prefer cinema. Additional terms for the field in general include the big screen, the silver screen, the cinema and the movies.
