against sun

sun (sʌn)
—n
1.	the star at the centre of our solar system. It is a gaseous body having a highly compressed core, in which energy is generated by thermonuclear reactions (at about 15 million kelvins), surrounded by less dense radiative and convective zones serving to transport the energy to the surface (the photosphere). The atmospheric layers (the chromosphere and corona) are normally invisible except during a total eclipse.

sun

the fem. pronoun was used until 16c.; since then masc. has prevailed. The empire on which the sun never sets (1630) originally was the Spanish, later the British. To have one's place in the sun (1680s) is from Pascal's "Pensées"; the Ger. imperial foreign policy sense (1897) is from a speech by von Bülow. The U.S. Sunbelt is first recorded 1969. Sunlight is first recorded c.1200. Sunbeam was in O.E.; sunset first recorded 1390 (sundown is from 1620); sunrise is first found mid-15c. (sun-up is from 1712). Sundial is from 1590s. Sunspot in ref. to the solar phenomenon is from 1868. Egg served sunny side up first attested 1900. Sunroof of a car is from 1966.

sun

1519, "to set something in the sun," from sun (n.). Meaning "to expose oneself to the sun" is recorded from 1610. Sun-bathing is attested from 1600. Sun-tan (v.) is recorded from 1821; the noun is first attested 1904. Sunburn (v.) is from sunne y-brent (c.1400).

sun   (sŭn)  Pronunciation Key  (click for larger image in new window) Often Sun. A medium-sized, main-sequence star located in a spiral arm of the Milky Way galaxy, orbited by all of the planets and other bodies in our solar system and supplying the heat and light that sustain life on Earth. Its diameter is approximately 1.4 million km (868,000 mi), and its mass, about 330,000 times that of Earth, comprises more than 99 percent of the matter in the solar system. It has a temperature of some 16 million degrees C (27 million degrees F) at its core, where nuclear fusion produces tremendous amounts of energy, mainly through the series of reactions known as the proton-proton chain. The energy generated in the core radiates through a radiation zone to an opaque convection zone, where it rises to the surface through convection currents of the Sun's plasma. The Sun's surface temperature (at its photosphere) is approximately 6,200 degrees C (11,200 degrees F). Turbulent surface phenomena analogous to the Earth's weather are prevalent, including magnetic storms, sunspots, and solar flares. The Sun was formed along with the rest of the solar system about 4.5 billion years ago and is expected to run out of its current hydrogen fuel in another 5 billion years, at which point it will develop into a red giant and ultimately into a white dwarf. See Table at solar system. See Note at dwarf star.

sun definition

The star around which the Earth revolves.

Note: The sun is about 4.5 billion years old and is expected to remain in its present state for approximately another six billion years; it will eventually evolve into a white dwarf.

Sun

n. Sun Microsystems. Hackers remember that the name was originally an acronym, Stanford University Network. Sun started out around 1980 with some hardware hackers (mainly) from Stanford talking to some software hackers (mainly) from UC Berkeley; Sun's original technology concept married a clever board design based on the Motorola 68000 to BSD Unix. Sun went on to lead the worstation industry through the 1980s, and for years afterwards remained an engineering-driven company and a good place for hackers to work. Though Sun drifted away from its techie origins after 1990 and has since made some strategic moves that disappointed and annoyed many hackers (especially by maintaining proprietary control of Java and rejecting Linux), it's still considered within the family in much the same way DEC was in the 1970s and early 1980s.

Sun definition

(Heb. shemesh), first mentioned along with the moon as the two great luminaries of heaven (Gen. 1:14-18). By their motions and influence they were intended to mark and divide times and seasons. The worship of the sun was one of the oldest forms of false religion (Job 31:26,27), and was common among the Egyptians and Chaldeans and other pagan nations. The Jews were warned against this form of idolatry (Deut. 4:19; 17:3; comp. 2 Kings 23:11; Jer. 19:13).
