Larva halftones:

1254-1346 A Venitian trader and explorer; one of the first westerners to travel to China on the [[Silk Road]].<ref>http://www.kyrene.org/schools/brisas/sunda/great/2amy.htm</ref>

A fun childrens game is called Marco Polo and is played in a swimming pool. One kid closes his eyes and yells "Marco" and the rest yell "Polo" the child with his eyes closed has to try to tag one of the other children.

Electron

2007-03-17T08:24:21Z

Larva halftones:

An electron is one of the [[fundamental particles]]. It is a [[lepton]] with a rest mass of 9.1093897*10^-31kg and carries the [[fundamental charge]] of -1.60218925*10^-19 C. An electron is a spin 1/2 particle which obeys Fermi-Dirac Statistics.<ref>Gribbin: ''Q is for Quantum''</ref>

The scientific definition of energy is the ability to do work.<ref>Wile, Dr. Jay L. ''Exploring Creation With Chemistry''. Apologia Educational Ministries, Inc. 1998</ref> In physics, energy is a conserved quantity, and a closed system of interacting particles is known to always have the same value for its energy; this is known as the law of conervation of energy.<ref>Halliday, Resnick, Walker: '' Fundamentals of Physics'', 6th Edition</ref>

Wave

2007-03-17T08:15:43Z

Larva halftones:

A wave is a disturbance which, in general, propagates through a medium in space. Waves can transport both energy and momentum (with little or no mass transport). Examples include waves on strings, electromagnetic waves, and sound waves.

Photons

Larva halftones:

A Photon is a quantised packet of electromagnetic radiation <ref>A French, P Taylor.(1978). A Introduction to Quantum Physics. MIT: CRC Press.</ref>. It is the elementary exchange particle for the electromagnetic force. The Energy of a photon depends on its frequency and is given by the equation:

'''E = hf'''

where '''f''' is the frequency of the electromagnetic wave and h is Plank's constant and has the numerical value of 6.626*10^-34 J*s or 4.135*10^-15 eV*s.

Dusty plasma

2007-03-17T07:28:57Z

Larva halftones:

A dusty plasma is a [[plasma | Plasma]] with particles of solid matter in it, each particle usually has a diameter on the order of 10 micrometers

Plasma

2007-03-17T07:24:08Z

Larva halftones:

A plasma is an gas where some or all of its atoms have had their electrons stripped off, this state is called ionized. Therefore, a plasma consists of both negatively charged electrons, and positively charged ions.
A plasma is generally regarded as the 4th state of matter.
