Topics related to "scintillation"

scintillation counter
scintillation counter device for detecting and measuring radiation by means of tiny visible flashes produced by the radiation when it strikes a sensitive substance known as a phosphor (see phosphorescence ). Phosphors used in scintillation counters include zinc sulfide, sodium iodide, various li... Read more
pulsar
pulsar in astronomy, a neutron star that emits brief, sharp pulses of energy instead of the steady radiation associated with other natural sources. The study of pulsars began when Antony Hewish and his students at Cambridge built a primitive radio telescope to study a scintillation effect on radi... Read more
seeing
seeing in astronomy, the clarity with which stars and other celestial objects can be observed. It is primarily determined by the atmosphere of the earth. The most obvious phenomenon is twinkling, when the brightness of a star seems to fluctuate. Known to astronomers as scintillation, twinkling is c... Read more
Giovanni Battista Tiepolo
Giovanni Battista Tiepolo , 1696-1770, Italian painter, b. Venice. He was the most important Venetian painter and decorator of the 18th cent. His frescoes in the Labia Palace and the doge's palace won him international fame. In 1750, Tiepolo was summoned to Würzburg, where he decorated the pala... Read more
musicals
musicals earlier known as musical comedy, plays that incorporate music, song, and dance. These elements move with the plot, heightening and commenting on the action. Mixing the sprightly songs and sketchy plots of operetta with the topical numbers of the revue , musical comedy began in En... Read more
stained glass
stained glass in general, windows made of colored glass. To a large extent, the name is a misnomer, for staining is only one of the methods of coloring employed, and the best medieval glass made little use of it. Background Colored glass as window decoration is of great antiquity in East ... Read more
