Welcome to PhysicsWiki,

The universe we live in is a place of vastness beyond human conception. It has principles of operation that can be divined by observation, analysis, and calculation. It is the goal of this organization to attempt to set an order to those principles in a fashion that results in the unification of the principles into a coherent calculable science.

47 Tucanae

Tucana is a constellation of stars in the southern sky, named after the toucan, a South American bird. It is one of twelve constellations conceived in the late sixteenth century by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman. It first appeared on a 1598 celestial globe by Plancius and Jodocus Hondius in Amsterdam and was depicted in Johann Bayer's star atlas Uranometria of 1603. French explorer and astronomer Nicolas Louis de Lacaille gave its stars Bayer designations in 1756. Tucana is not a prominent constellation as all of its stars are third magnitude or fainter; the brightest is Alpha Tucanae with an apparent visual magnitude of 2.87. Beta Tucanae is a star system with six member stars, while Kappa is a quadruple system. Five star systems have been found to have exoplanets to date. The constellation contains most of the Small Magellanic Cloud, along with 47 Tucanae (pictured), one of the brightest globular clusters in the sky. The constellations Tucana, Grus, Phoenix and Pavo are collectively known as the "Southern Birds". (Full article...)

Original & Experimental Material

PhysicsWiki welcomes the addition of Original, Theoretical & Experimental Material. The articles in this area should not be considered as reference material. They are the real reason for the existence of PhysicsWiki. PhysicsWiki is a place where we can explore ideas regarding any area of physics in a collaborative fashion. This area is not a BLOG but it is for placing challenging views about the science of physics up for anyone to examine.
The synopsis below is an open dialog regarding the defination energy
Merriam-Webster's Full Definition of ENERGY

1 a : dynamic quality <narrative energy>

 b :  the capacity of acting or being active <intellectual energy>
 c :  a usually positive spiritual force <the energy flowing through all people>

2: vigorous exertion of power : effort <investing time and energy> 3: a fundamental entity of nature that is transferred between parts of a system in the production of physical change within the system and usually regarded as the capacity for doing work 4: usable power (as heat or electricity); also : the resources for producing such power


A Proposed New Definition of Energy
  • A field of existence having finite boundaries, that are infinitely variable and exhibiting infinitely variable topology. The field occupies no more than 2 dimensions of space and has a constant entropic condition.
Properties
  • An energy field will exhibit polar properties due to its motion in space/time. Those properties are positive on the surface that is exposed to the direction of motion and negative on the surface that is opposite the direction of motion. These fields appear to exist always at right angles to the direction of propagation.
  • Entropic condition is caused by interactions between different energy fields and between energy fields and matter. These interactions are caused by the polar relationships of energy fields. Since all fields are constantly in motion, one will always exhibit the characteristic of repelling any other field that is directionally opposed to it.
  • Energy fields are always in motion relative to our perception of the universe, or we may be in motion relative to energy fields.
  • The topology of an energy field may have an almost infinite variety of configurations. A visual example would be to consider an impossibly thin sheet of plastic wrap. It has elastic properties and may be shaped in a variety of ways, but it only has two surfaces and a finite boundary.
  • The behavior of all energy fields is that of a somewhat elastic surface that has infinite properties of flexibility.

NGC 1300 is a barred spiral galaxy about 61 million light-years away in the constellation Eridanus. The galaxy is about 110,000 light-years across; just slightly larger than our own galaxy, the Milky Way.
