cleanup date January 2010 Terrestrial stationary waves is a persistent spherical Electrical conductor conductor single wire surface wave electricity electrical transmission line phenomenon arising across the Earth s surface by virtue of the highly conductive nature of the earth itself. It was considered by Nikola Tesla to be his most important discovery. Earth s surface constitutes an interface that supports the wave. On July 3, 1899, Tesla claimed discovery of this new geo electrical phenomenon, which he said would allow for the transmission of electrical energy around the world. quote That communication without wires to any point of the globe is practicable with such apparatus would need no demonstration, but through a discovery which I made I obtained absolute certitude. Popularly explained, it is exactly this When we raise the voice and hear an echo in reply, we know that the sound of the voice must have reached a distant wall, or boundary, and must have been reflected from the same. Exactly as the sound, so an electrical wave is reflected, and the same evidence which is afforded by an echo is offered by an electrical phenomenon known as a stationary wave that is, a wave with fixed nodal and ventral regions. Instead of sending sound vibrations toward a distant wall, I have sent electrical vibrations toward the remote boundaries of the earth, and instead of the wall the earth has replied. In place of an echo I have obtained a stationary electrical wave, a wave reflected from afar. ref http www.tfcbooks.com tesla 1900 06 00.htm THE PROBLEM OF INCREASING HUMAN ENERGY , Century Magazine, June 1900 ref Terrestrial stationary waves were first observed by Tesla and formed the basis ... of the stationary terrestrial waves, showing that, despite its vast extent, the entire planet can ...

If many sinusoids have the same phase and they are added together, they will add constructively. If, however, these same sinusoids have phases which change rapidly as the frequency changes, they will add incoherently, varying between constructive and destructive addition at different times.

SHARP , short for Stationary High Altitude Relay Platform , was an experimental aircraft using beam powered propulsion designed by the Communications Research Centre Canada CRC and built by the University of Toronto Institute for Aerospace Studies UTIAS during the 1980s. SHARP used microwaves to provide energy from a ground station that powered electric motors spinning propellers to keep the aircraft aloft. The power was also used for the onboard electronics. SHARP could remain aloft indefinitely, and was intended to be used as a sort of low altitude communications satellite for smaller geographical areas. History Background The concept of using beamed power for aircraft propulsion was invented almost single handedly by William C. Brown . ref Sheldon Hochheiser, http www.ieeeghn.org wiki index.php William C. Brown William C. Brown Biography , IEEE Global History Network, 29 August 2008 ref After joining Raytheon in the 1940s, Brown started work on improving their magnetron products. This led to the development of the crossed field amplifier , a simple, reliable and highly efficient microwave amplifier .

Regulation of the equipment used in the event was done through proscribing ammunition weighing more than 140 grains, with a velocity of more than 1,450 feet per second, or having a hard metal base. Each shooter fired 80 shots, half at 50 yards and half at 100 yards. Maximum score for a shot was 5 points, giving a maximum total possible of 400 points. Twelve competitors from each nation were allowed to take part. Because of a delay in the arrival of Barnes registration, the British team registered Philip Plater as a replacement. The original registration later arrived, resulting in Britain having 13 entrants. Further confusion on the day of competition resulted in all 13 shooting, Plater going last. Plater, who had scored 391 points to place first in the event and set a world record, was ruled to have been the illegal competitor and his score was invalidated. ref name Plater cite web url http www.rifleman.org.uk W.W.Greener martini target rifles.htm title W.

It was conceived of and edited by Matt Weiland and Sean Wilsey . Background Weiland and Wilsey stated that they were inspired by the Federal Writers Project of the 1930 s, in which the US government helped to create jobs by sending writers across the country and commissioning pieces on their sights and experiences. The two previously edited Thinking Fan s Guide to the World Cup , in which they commissioned 32 authors to write pieces on the 32 countries competing in the 2006 World Cup they decided a similar approach could be taken with the United States. Both Weiland and Wilsey decided that they wanted a mixture of approaches for the collection while several well known authors eg, Ha Jin , Jhumpa Lahiri , Dave Eggers were included, they deliberately avoided certain authors that were closely associated with a particular state for instance, Garrison Keillor with Minnesota , or Carl Hiaasen with Florida . The collection has a mix of familiarity, with some authors writing about places in which they have lived their entire lives, while others visited the state for the first time.

In probability theory and statistical mechanics , a Gibbs state is an equilibrium probability distribution which remains invariant under future evolution of the system. For example, a stationary or steady state distribution of a Markov chain , such as that achieved by running a Markov chain Monte Carlo iteration for a sufficiently long time, is a Gibbs state. Precisely, suppose math L math is a generator of evolutions for an initial state math rho 0 math , so that the state at any later time is given by math rho t e L t rho 0 math . Then the condition for math rho infty math to be a Gibbs state is math L rho infty 0 math . In physics there may be several physically distinct Gibbs states in which a system may be trapped, particularly at lower temperatures. They are named after J. Willard Gibbs , for his work in determining equilibrium properties of statistical ensemble s.

Reid title ...Thermodynamics cTopic Thermodynamic system Systems A thermodynamic state is a set of values of properties of a Thermodynamics thermodynamic Thermodynamic system system that must be specified to reproduce the system. The individual parameters are known as state variables , state parameters or thermodynamic variables . Once a sufficient set of thermodynamic variables have been specified, values of all other properties of the system are uniquely determined. The number of values required to specify the state depends on the system, and is not always known. State functions Main State function State functions , also called thermodynamic variables , state quantities , or a functions of state describe the momentary condition of a thermodynamic system. Regardless of the path by which a system goes from one state to another i.e., the sequence of intermediate states the total change in any state variable will be the same. This means that the incremental changes in such variables are exact differential s .

After absorbing energy , an electron may Atomic electron transition jump from the ground state to a higher energy excited state. The ground state of a quantum mechanics quantum mechanical system is its lowest energy stationarystatestate the energy of the ground state is known as the zero point energy of the system. An excited state is any state with energy greater than the ground state. The ground state of a quantum field theory is usually called the vacuum state or the vacuum The quantum mechanical vacuum vacuum . If more than one ground state exists, they are said to be degenerate energy level degenerate . Many systems have degenerate ground states. It turns out that degeneracy occurs whenever a nontrivial unitary operator commutator commutes with the Hamiltonian quantum mechanics Hamiltonian of the system. According to the third law of thermodynamics , a system at absolute zero temperature exists in its ground state thus, its entropy is determined by the degeneracy of the ground state. Many systems, such as a perfect crystal lattice , have a unique ground state and therefore have zero entropy at absolute zero because the logarithm of 1 is 0.
