Salyut 7 space station in orbit

The Salyut 7 space station photographed in orbit. Attached to the space station at bottom, with the separate solar panels, is the Soyuz T14 ferry spacecraft. Soyuz T14 was launched on 17 September 1985 and carried cosmonauts Vladimir Vasyutin, Alexander Volkov and Georgi Grechko to Salyut 7. Their mission was terminated when Vasyutin became seriously ill, and they returned to Earth on 22 November 1985

Portrait of Pavel Cerenkov

Pavel Cerenkov, Russian physicist, born Voronezh Guberniya on August 10, 1904, photographed (on right) at the controls of a synchrotron at the Institute of Physics of the Soviet Academy of Science, in 1959. His important discovery in 1934 involved the velocity of high-energy subatomic particles, which is never greater than the velocity of light in a vacuum. Light travelling through water, however, moves more slowly: a high- energy particle moving through water may exceed the velocity of light in that medium. When it does it creates a "wake" of light - termed Cerenkov radiation. For this work, Cerenkov, Frank & Tamm shared the 1958 Nobel Prize in physics

Asthma inhaler use

Illustration showing the use of a Ventolin inhaler to control recurrent attacks of asthma, featuring a cutaway drawing of a man which shows the "tree" of branching airways in both lungs. A cross- section through a division of a bronchus is shown in detail at bottom right. A Ventolin inhaler contains the drug salbutamol, which dilates the bronchial muscles allowing air to pass to the lungs. In bronchial asthma a narrowing of the airways is produced by spasm of the muscles in the bronchial tubes. These spasms are associated with swelling of the lining surfaces accompanied by an increased in mucous secretion
