TRANSLATION

1. Noise, in physics, is an acoustic, electric, or electronic signal consisting of a random mixture of wavelengths. In information theory, the term designates a signal that contains no information. In acoustics, “white” noise consists of all audible frequencies, just as white light consists of all visible frequencies. Noise is also a subjective term, referring to any unwanted sound.

2. Space, in general usage, is that which is characterized by the property of extension or the ability to stretch out or extend in any direction; in astronomy, the region beyond the earth's atmosphere or beyond the solar system: outer space. The so-called actual space in which material objects exist and are perceived was regarded for many thousands of years as having three dimensions: left and right, up and down, and forward and backward.

3. Modern investigations in mathematics, physics, and astronomy have indicated that space and time are actually extensions of the same continuum, which scientists refer to as space-time or the space-time continuum.

4. A television program is created by focusing a television camera on a scene. The camera changes light from the scene into an electric signal, called the video signal, which varies depending on the strength, or brightness, of light received from each part of the scene. In color television, the camera produces an electric signal thatvaries depending on the strength of each color of light.

5. Refrigeration is the process of lowering the temperature and maintaining it in a given space for the purpose of chilling foods, preserving certain substances, or providing an atmosphere conducive to bodily comfort. Storing perishable foods, furs, pharmaceuticals, or other items under refrigeration is commonly known as cold storage. Such refrigeration checks both bacterial growth and adverse chemical reactions that occur in the normal atmosphere.
