The concept of zero-point energy occurs in a number of situations.

As a scientific concept, the existence of zero-point energy is not controversial although the ability to harness it is.

This is interesting for it combines both the thermodynamic concept of a minimum Gibbs function for equilibrium and minimum mechanical potential energy for equilibrium.

The concept of the strain energy as a Gibbs function difference Af and exerting a force normal to the shearing face is compatible with the information obtained from optical birefringence studies of fluids undergoing shear.

Breatharianism is a related concept, in which believers claim food and possibly water are not necessary, and that humans can be sustained solely by prana ( the vital life force in Hinduism ), or, according to some, by the energy in sunlight ( according to Ayurveda, sunlight is one of the main sources of prana ).

It is a concept album about the persistence of matter, energy and memory in the Universe.

The concept of the Dyson sphere was the result of a thought experiment by physicist and mathematician Freeman Dyson, when he theorized that all technological civilizations constantly increased their demand for energy.

Ørsted's discovery also represented a major step toward a unified concept of energy.

This definition of potential, while formal, has little practical application, and a more useful concept is that of electric potential difference, and is the energy required to move a unit charge between two specified points.

Food webs are a type of concept map or a heuristic device that is used to illustrate and study pathways of energy and material flows.

The concept of energy emerged out of the idea of vis viva ( living force ), which Gottfried Leibniz defined as the product of the mass of an object and its velocity squared ; he believed that total vis viva was conserved.

It also led to a mathematical formulation of the concept of entropy by Clausius and to the introduction of laws of radiant energy by Jožef Stefan.

During a 1961 lecture for undergraduate students at the California Institute of Technology, Richard Feynman, a celebrated physics teacher and Nobel Laureate, said this about the concept of energy:

Thus, it is this semi-empirical formula for bond energy that underlies Pauling electronegativity concept.

The concept is frequently applied in the physical sciences to chemical reactions, where chemical bond energy is converted to thermal energy ( heat ).

The concept is frequently applied in physical sciences to, for example, chemical reactions, where thermal energy ( heat ) is converted to chemical bond energy.

Although forests are classified primarily by trees, the concept of a forest ecosystem includes additional species ( such as smaller plants, fungi, bacteria, and animals ) as well as physical and chemical processes such as energy flow and nutrient cycling.

" Verena Frank, project manager at Beluga Shipping GmbH, SkySails GmbH's partner further stated that " the project's core concept was using wind energy as auxiliary propulsion power and using wind as a free of charge energy ".

This was an enormous theoretical leap, but the concept was strongly resisted at first because it contradicted the wave theory of light that followed naturally from James Clerk Maxwell's equations for electromagnetic behavior, and more generally, the assumption of infinite divisibility of energy in physical systems.

Later the concept was expanded greatly to comprise any interaction with radiative energy as a function of its wavelength or frequency.

At the low extreme of size is the concept of micro-SMES solenoids, for energy storage range near 1 MJ.

Catholics charge that modalistic monarchianism has its origin by means of influence in Greek pagan philosophy, including pagan philosophers like Euclid and Aristotle, who based their logic on Monism and Aristotle's arguments around his concept energeia ( i. e. energy ) called metaphysics.

Thermochemistry coalesces the concepts of thermodynamics with the concept of energy in the form of chemical bonds.

However, this notion is problematic for a standing wave ( for example, a wave on a string ), where energy is moving in both directions equally, or for electromagnetic ( e. g., light ) waves in a vacuum, where the concept of medium does not apply and interaction with a target is the key to wave detection and practical applications.

Jean Bodin, writing in the sixteenth century, may have been the seminal thinker, but it was the vastly influential John Austin who set out the main lines of the concept as now understood.

They recognized that slavery was a moral issue and not merely an economic interest, and that to recognize it explicitly in their Constitution would be in explosive contradiction to the concept of sovereignty they had set forth in the Declaration of 1776 that `` all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among them are life, liberty and the pursuit of happiness.

But though the Southern States, when drafting a constitution to unite themselves, narrowed the difference to this fine point by omitting to assert the right to secede, the fact remained that by seceding from the Union they had already acted on the concept that it was composed primarily of sovereign states.

What was perhaps more important than his concept of the nature of history and the historical method were those forces which shaped the direction of his thought.

There was only one way to accomplish this: by design, by drawing diagrams and sketches in which he probed the remotest corner of his mind for creative ideas to carry his concept.

what mattered was that a new concept of Americans was being born.

The concept of the Middle Kingdom at peace, strong and united under a forceful ruler, which had been only a longed-for ideal in the time of the Warring States, was finally realized by the establishment of a Chinese Empire under the Ch'in dynasty ( 221-207 B.C. ).

there was no Martian concept to match it -- unless one took `` church '' and `` worship '' and `` God '' and `` congregation '' and many other words and equated them to the totality of the only world he had known during growing-waiting then forced the concept back into English in that phrase which had been rejected ( by each differently ) by Jubal, by Mahmoud, by Digby.

He was closer to understanding it in English now, although it could never have the inevitability of the Martian concept it stood for.

`` I did not perceive this essential distinction either, First-Born '', Hesperus said at once, `` I was only practicing a concept that Jack taught me, called a deal ''.

This concept was emphasized by Sufi mystics like Rabia al-Adawiyya who paid attention to the difference between dedication to Allah ( i. e. God ) and dedication to people.

The zero was probably introduced to the Chinese in the Tang Dynasty ( 618-907 AD ) when travel in the Indian Ocean and the Middle East would have provided direct contact with India, allowing them to acquire the concept of zero and the decimal point from Indian merchants and mathematicians.

A third concept was proposed in 1923 by Gilbert N. Lewis which includes reactions with acid-base characteristics that do not involve a proton transfer.

The concept of an atom as an indivisible component of matter was first proposed by early Indian and Greek philosophers.

As it took many years for the name " The Ashes " to be given to the ongoing series between England and Australia, there was no concept of there being a representation of the ashes being presented to the winners.

Ford was the first company to build large factories around the assembly line concept.

The assembly line concept was independently redeveloped throughout history and not " invented " at one time by one person.

A peculiar feature of these Taoist thinkers, like the Seven Sages of the Bamboo Grove, was the concept of feng liu ( lit.

Rabbi Trugman states that in the last five centuries the concept of reincarnation, which until then had been a much hidden tradition within Judaism, was given open exposure.

The Arian concept of Christ is that the Son of God did not always exist, but was created by — and is therefore distinct from — God the Father.

Woolfson, a songwriter and composer, was working as a session pianist ; he had also composed material for a concept album idea based on the work of Edgar Allan Poe.

A grant application to build a proof of concept prototype was submitted in March 1939 to the Agronomy department which was also interested in speeding up computation for economic and research analysis.
