bending of light rays passing close to the sun because of the sun’s gravitational field ( see Relativity). The great brilliance of the solar disk and the sun-induced brightening of the earth’s atmosphere make observations of the corona and nearby stars impossible except during a solar eclipse. The coronagraph, a photographictelescope, permits direct observation of the edge of the solar disk at all times. Today, scientific solar eclipse observations are extremely valuable, particularly when thepa...

Pluto - astronomy.
depended on how Pluto was classified. The status of Pluto drew world attention in 2006 when the official body that governs the naming of astronomical objects, the International Astronomical Union (IAU),voted for an official definition of the term planet . According to the standards adopted, a “classical planet” must orbit the Sun, must have a rounded shape from effects of its own gravity, and must be the dominant object in its region of space, having cleared the neighborhood of its orbit of oth...

Astronomy - astronomy.
Telescopes may use either lenses or mirrors to gather visible light, permitting direct observation or photographic recording of distant objects. Those that use lenses arecalled refracting telescopes, since they use the property of refraction, or bending, of light ( see Optics: Reflection and Refraction ). The largest refracting telescope is the 40-in (1-m) telescope at the Yerkes Observatory in Williams Bay, Wisconsin, founded in the late 19th century. Lenses bend different colors of light by d...

Boucher's Diana resting after her Bath, not a mythological painting !!!
size. Mythological paintings were often painted on large canvases to symbolize the divinity and importance of the immortals depicted. The Rococo Movement is characterized by small canvases that were made to fit on wooden panels of smaller apartments, and “Diana Resting After Her Bath”, which measures 57 × 73 cm (22.4 × 28.7 in), would thus refer more to the characteristic of a genre painting than a mythological one. Furthermore, Diana is more sensual than a huntress, as she is nude....

Ellroy, James - écrivain.
4 UN ÉCRIVAIN HORS NORMES James Ellroy est aujourd’hui l’un des auteurs de romans noirs américains les plus populaires. Il a réussi à canaliser ses pulsions les plus sombres pour les transcender dans le roman noir. Son style cru et acide dépeint les recoins sombres de la société américaine. Il s’intéresse particulièrement aux structures et au fonctionnement de l’État ainsi qu’à ses pratiques policières. Ses romans revêtent une dimension historique, notamment ceux de la trilogie Underworld U.S....

Radar.
gathers the weak returning radar signals and converts them into an electric current. Because a radar antenna may both transmit and receive signals, the duplexerdetermines whether the antenna is connected to the receiver or the transmitter. The receiver determines whether the signal should be reported and often does furtheranalysis before sending the results to the display. The display conveys the results to the human operator through a visual display or an audible signal. B1 The Antenna The rec...

Earth (planet).
Milky Way to complete one revolution around the Galaxy’s center. Earth’s axis of rotation is inclined (tilted) 23.5° relative to its plane of revolution around the Sun. This inclination of the axis creates the seasons and causes the height of the Sun in the sky at noon to increase and decrease as the seasons change. The Northern Hemisphere receives the most energy from the Sun when it is tiltedtoward the Sun. This orientation corresponds to summer in the Northern Hemisphere and winter in the S...

Volcano.
before eruption. Very violent explosive eruptions are called Plinian eruptions, after Roman naturalist Pliny the Elder. These eruptions can last for several hours to daysand eject a large amount of pyroclastic material. Some volcanoes can produce much more energetic eruptions that eject materials farther from the vents because oftheir andesitic and dacitic composition. Andesitic and dacitic lava is generally thicker than basaltic lava. Stiff lava generally produces more-explosive eruptions. B No...

repetition of certain lines and the rhyming of certain lines. The Provençal sestina features a set of six words that end lines (end-words), repeated in a dizzyingly complexpattern. The range of effects created by the poetic line varies tremendously depending on its length, its patterns of repetition, and whether the sentence stops at the end of theline (end-stopped) or carries over the end of the line (enjambed). Many of the earliest examples of Old English poetry feature an accentual line with...

Idaho - geography.
Idaho-Montana state line in the southern part of the Bitterroot Mountains. Consequently, nearly all the rivers in the state drain toward the Pacific. Most of Idaho lieswithin the drainage basin of the Columbia River system. The Snake River, which is the chief river in southern and central Idaho, follows a crescent-shaped course forabout 790 km (about 490 mi) across southern Idaho. It then swings northward along the Idaho state line and joins the Columbia River in Washington. Major tributariesof...
