1. The luminous orb, the light of which constitutes day, and
its absence night; the central body round which the earth
and planets revolve, by which they are held in their
orbits, and from which they receive light and heat. Its
mean distance from the earth is about 92,500,000 miles,
and its diameter about 860,000.
[1913 Webster]
Note: Its mean apparent diameter as seen from the earth is
32' 4[sec], and it revolves on its own axis once in
251/3 days. Its mean density is about one fourth of
that of the earth, or 1.41, that of water being unity.
Its luminous surface is called the photosphere, above
which is an envelope consisting partly of hydrogen,
called the chromosphere, which can be seen only through
the spectroscope, or at the time of a total solar
eclipse. Above the chromosphere, and sometimes
extending out millions of miles, are luminous rays or
streams of light which are visible only at the time of
a total eclipse, forming the solar corona.

Sun and planet wheels (Mach.), an ingenious contrivance for
converting reciprocating motion, as that of the working
beam of a steam engine, into rotatory motion. It consists
of a toothed wheel (called the sun wheel), firmly secured
to the shaft it is desired to drive, and another wheel
(called the planet wheel) secured to the end of a
connecting rod. By the motion of the connecting rod, the
planet wheel is made to circulate round the central wheel
on the shaft, communicating to this latter a velocity of
revolution the double of its own. --G. Francis.

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 workstation 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 - Easton's 1897 Bible Dictionary :
Sun
(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).
