Kvant (magazine)

Kvant (Russian: Квант for "quantum") is a popular science magazine in physics and mathematics for school students and teachers, issued since 1970 in Soviet Union and continued in Russia. Translation of selected articles from Kvant had been published in Quantum Magazine in 1990–2001, which in turn had been translated and published in Greece in 1993–2001.

History

Kvant was started as a joint project of the USSR Academy of Sciences and USSR Academy of Pedagogical Sciences. In Soviet time, it was published by Nauka publisher with circulation about 200,000.

The idea of the magazine was introduced by Pyotr Kapitsa. Its first chief editors were physicist Isaak Kikoin and mathematician Andrei Kolmogorov. In 1985, its editorial board had 18 Academicians and Corresponding Members of the USSR Academy of Sciences and USSR Academy of Pedagogical Sciences, 14 Doctors of Sciences and 20 Candidates of Science.

All published issues of Kvant are freely available online.

Grip (job)

In the U.S. and Canada, grips are lighting and rigging technicians in the filmmaking and video production industries. They constitute their own department on a film set and are directed by a key grip. Grips have two main functions. The first is to work closely with the camera department to provide camera support, especially if the camera is mounted to a dolly, crane, or in an unusual position, such as the top of a ladder. Some grips may specialize in operating camera dollies or camera cranes. The second main function of grips is to work closely with the electrical department to create lighting set-ups necessary for a shot under the direction of the director of photography.

In the UK, Australia and most parts of Europe, grips are not involved in lighting. In the "British System", adopted throughout Europe and the British Commonwealth (excluding Canada), a grip is solely responsible for camera mounting and support.

The term "grip" is from the early era of the circus. From there it was used in vaudeville and then in today's film sound stages and sets. Some have suggested the name comes from the 1930s–40s slang term for a tool bag or "grip" that these technicians use to carry their tools. Another theory is that in the days of hand-cranked cameras, it was necessary for a few burly men to hang on to the tripod legs to stop excessive movement of the camera. These men became known as the "good grips"—as they were constantly being instructed to "keep a good grip on the tripod".

Grip (gymnastics)

Grips are devices that are worn on the hands of artistic gymnasts when performing on various gymnastics apparatus. They are worn by female gymnasts on the uneven bars, and by male gymnasts on the high bar, and still rings; is rarely seen that a male gymnast uses grips for parallel bars. They are used to enhance the gymnast's grip on the apparatus, and also to reduce (but not eliminate) the friction that can cause painful blisters and rips, in which outer layers of skin separate and tear away from the hand.

Grips are optional and are not used by all gymnasts. Some athletes substitute sports tape or gauze for grips, while others use bare hands. Gymnasts typically apply powdered chalk (typically magnesium carbonate) to their grips, or to their hands if not using grips.

Construction

A grip consists of a wide strip of leather joined to a wrist strap. The leather strip, which covers and protects the palm of the hand, is approximately five centimeters wide and has finger holes at one end. On properly fitted grips, the finger holes will be positioned at the first knuckles of the inserted fingers.
