"Mean Creek" opens with a schoolyard bully picking on a smaller kid, develops into a story of revenge, and then deepens into the surprisingly complex story of young teenagers trying to do the right thing.
Jacob Aaron Estes, who wrote and directed "Mean Creek," shows in his first film a depth of empathy for his characters, and for the ways the strong-willed ones control the others.
"Mean Creek" joins a small group of films including "The River's Edge" and "Bully," which deal accurately and painfully with the consequences of peer-driven behavior.

A fictitious sun which is assumed to move in the celestial equator at a uniform speed corresponding to the average angular speed of the real Sun in the ecliptic, the mean sun being alternately in advance and behind the real Sun.
It is used as a reference for reckoning mean time, noon of mean local time corresponding to the time of the transit of the mean sun over the local meridian.

 Greenwich Mean Time - Wikipedia, the free encyclopedia
Greenwich Mean Time (GMT) is mean solar time at the Royal Greenwich Observatory in Greenwich, London, England, which by convention is at 0 degrees geographic longitude.
Noon Greenwich Mean Time is not the moment when the Sun crosses the Greenwich meridian (and reaches its highest point in the sky in Greenwich) because of Earth's uneven speed in its elliptic orbit and its axial tilt.
The fictitious mean sun is the annual average of this nonuniform motion of the true Sun, necessitating the inclusion of mean in Greenwich Mean Time.

 Company Seven | Technical Information: Principles of the Sun Earth Relationship As Demonstrated by Geochron
However, the speed of the Earth's travel around the Sun varies so that over a period of one year, some days are shorter and others longer, causing the relative zenith, or noon position of the Sun to vary accordingly.
For time measurement purposes, man has taken the "mean" between the longest and the shortest apparent solar days, divided it into 24 equal hours, and thus had "mean solar time." When our clocks say 12 o'clock "mean time", it does not necessarily indicate that the Sun is at its zenith.
The Sun, Sunrise, and Sunset mechanism system is driven by a synchronous motor coupled to a gear train which reduces the speed to one revolution per year.

 Basic Astrology #4; the Mean Sun (MS) - MysticWicks Online Pagan Community and Pagan Forums
Since we are viewing the Sun from the Earth, it is the Sun that appears to travel the Zodiacal circle.
Where the appearent Sun (that which is visible) is in its orbit, around the Zodiac, is called the RA of the appearent Sun, or it is simply called R.A. This value is given daily in the more complete ephemerides.
The average (or mean) change is calculated by 24 hours (of RA) divided by 365.2564,(the amount of days for the Earth to orbit the Sun.) This yields a mean daily incrment of :03:56.546 minutes of RA per day.

 Tilt_Effect
If we observe the position of the sun every day at the same time each day we notice that throughout the year the sun moves slowly to the east against the background of the stars taking one year to return to its starting position.
The velocity of the Mean Sun and the True Sun are constant, each one taking one year to make a complete trip around the celestial sphere.
If we look at the position of the True Sun at noon in May, we should "expect" it to be in the position of the Mean Sun (remember that the Mean Sun at noon will be at culmination).

 U.S. Global Change Research Information Office
The enhanced solar activity that characterized the Sun at the peak of the last two cycles, in 1979- 1981 and again in 1989-1991, increased both the overall brightness and the amplitude of the rotational modulation.
Changes in the Sun's total radiation and how it is distributed in wavelength occur primarily because solar activity produces two different phenomena that alter the surface brightness, and hence modulate the outward flow of radiated energy.
The same isotopic records show that the Sun seems to have been building up over the last several hundred years to a state of enhanced activity that is the opposite of the suppressed levels of the 17th century Maunder Minimum.

 Equation of Time   (Site not responding. Last check: 2007-11-05)
The apparent motion of the sun as it crosses the sky is mostly affected by the earth's rotation.
A mean sun assumes a scenario where the sun comes across the sky at an equal speed every day, crossing the local meridian at the highest point in the sky at exactly noon every day.
The apparent sun and mean sun reach the local meridian at noon 4 times a year; then at other times of the year they differ.

This phenomenon is due in part to the inclination of the terrestrial rotation axis on the plane of the Earth orbit around the Sun and in part to the unequal motion of the Earth around the Sun, caused by the elliptical orbit.
To avoid this drawback, it was defined the mean solar time that has the mean solar day, equal to the mean duration of all days of year, as measurement unit.
To the definition of this time, it is associated an ideal Sun, called mean Sun, that has an uniform apparent motion.

Greenwich Mean Time (GMT) is the mean solar time at the Royal Greenwich Observatory in Greenwich near London in England, which by convention is at 0 degrees geographic longitude.
Theoretically, noon Greenwich Mean Time is the moment when the Sun crosses the Greenwich meridian (and reaches its highest point in the sky in Greenwich).
Because of the Earth's uneven speed in its elliptic orbit, this event may be up to 16 minutes off apparent solar time (this discrepancy is known as the equation of time); but this is averaged out over the year through the use of the mean sun.
