“Other qualities of bodies are connected with simple energy of motion and energy of position. Such is heat, which we find by experiment can be turned into work. Finding it convertible with energy, we call it a form of energy. ...But as to heat, it is further established by experiment that in this case the energy of motion does really persist as such. Thus a gas consists of molecules flying about with velocity, rotating and vibrating, and so having energy motion. All this energy of motion is what we call heat, and thus heat is a repetition of a known meaning of energy. Again, heat exists between a radiating body and the thing it warms; now the intermediate space is filled by the luminiferous ether, which, being elastic, has in its ultimate parts both energy of motion energy of position. In these forms the heat exists in the space in question.”

“When a body is let fall from a higher position to lower one, it has, at the instant when it is let go, energy of motion; but it gains, in falling, as much energy of motion as it loses energy of position. It is found that the sum of energy of motion and energy of position is always constant. ...Energy is a quantity which can be greater or less but has no direction. ...This constancy is expressed by including them in common name of Energy, and saying that energy is conserved, or is indestructible. This form of speech might be applied to other cases of alternate immortality, where one of two things comes into existence on disappearance of the other.”

“Another conspicuous failure of classical mechanics was with one aspect of the problem of radiation. …Imagine a crowd of steel balls rolling about on a steel floor. …There must… be a steady leakage of energy from… causes, such as air resistance and the friction of the floor, so the balls will eventually lose energy, and, after no great length of time, will be found standing at rest on the floor. The energy of their motion seems to have been lost… most of it has been transformed into heat. The classical mechanics predicts that this must happen; it shows that all energy of motion, except possibly a minute fraction of the whole, must be transformed into heat whenever such a transformation is physically possible. It is because of this that perpetual-motion machines are a practical impossibility.”

James Jeans (1877–1946) British mathematician and astronomer

Physics and Philosophy (1942)

“There is… something which is in energy only; and there is something which is both in energy and capacity. …of relatives, one is predicated as according to excess and defect: another according to the effective and passive, and, in short, the motive, and that which may be moved… Motion, however, has not a substance separate from things… But each of the categories subsists in a twofold manner in all things. Thus… one thing pertaining to it is form, and another privation. …So the species of motion and mutation are as many as those of being. But since in every genus of things, there is that which is in entelecheia, and that which is in capacity; motion is the entelecheia of that which is in capacity… That there is energy, therefore, and that a thing then happens to be moved, when this energy exists, and neither prior nor posterior to it, is manifest. … [N]either motion nor mutation can be placed in any other genus; nor have those who have advanced a different opinion concerning it spoken rightly. …for by some motion is said to be difference, inequality, and non-being; though it is not necessary that any of these should be moved… Neither is mutation into these, nor from these, rather than from their opposites. …The cause, however, why motion appears to be indefinite, is because it can neither be simply referred to the capacity, nor to the energy of beings. …[I]t is difficult to apprehend what motion is: for it is necessary to refer it either to privation, or to capacity, or to simple energy; but it does not appear that it can be any of these. The above-mentioned mode, therfore remains, viz. that it is a certain energy; but… difficult to be perceived, but which may have a subsistence.”

“The whole science of heat is founded Thermometry and Calorimetry, and when these operations are understood we may proceed to the third step, which is the investigation of those relations between the thermal and the mechanical properties of substances which form the subject of Thermodynamics. The whole of this part of the subject depends on the consideration of the Intrinsic Energy of a system of bodies, as depending on the temperature and physical state, as well as the form, motion, and relative position of these bodies. Of this energy, however, only a part is available for the purpose of producing mechanical work, and though the energy itself is indestructible, the available part is liable to diminution by the action of certain natural processes, such as conduction and radiation of heat, friction, and viscosity. These processes, by which energy is rendered unavailable as a source of work, are classed together under the name of the Dissipation of Energy.”

James Clerk Maxwell (1831–1879) Scottish physicist

“According to the Special Theory of Relativity, the velocity of a moving body is always less than the velocity of light. Since the energy of motion of a body depends on its inertial mass and its velocity, it follows that if the energy of a body is increased indefinitely by the continual application of a force, the inertial mass of the body must be increased too; for, if not, the velocity would ultimately increase indefinitely and exceed the velocity of light. Einstein found that, corresponding to any increase in the energy content of a body, there is an equivalent increase in its inertial mass. Mass and energy thus appeared to be different names for the same thing, the energy associated with a mass M being Mc2, where c is the velocity of light; and the mass M of a body moving with velocity v he found to be given by the following formulaM = \frac {m}{\sqrt{(1 - \frac {v^2}{c^2}}}</center”

“We can think in other terms. The energy of Aquarius is the energy of synthesis. So the energies of Pisces have left us divided... it has given us tremendous qualities... for example of individuality.”

Benjamin Creme (1922–2016) artist, author, esotericist

“When we understand that Who We Are is pure energy, the Essential Essence of Life itself, and that this energy not only composes us and comprises us, but is projected through us, from us, and outward into the world…and when we understand furthermore that energy affects other energy, that all energy impacts other energy…then we begin to understand that how we think about a thing determines how the thing is, and continues to be.”

Neale Donald Walsch (1943) American writer

“The more you get into material and matter, all you realize is in matter, there is energy. There is a blur between energy and consciousness. All material is conscious to some extent or another. All material can respond to some extent or another to vibrations of energy that is different to energy you learn about in physics.”

Dr. Moog (1934–2005) electronic music pioneer and inventor from the United States

From the film Moog (2004)
Context: The more you get into material and matter, all you realize is in matter, there is energy. There is a blur between energy and consciousness. All material is conscious to some extent or another. All material can respond to some extent or another to vibrations of energy that is different to energy you learn about in physics. There are all sorts of reliable information now on people and animal being able to be able to effect the operations of machines—even of computers—and I think that has great implications for what goes on between a musician and his instrument. There is a level of reality where there is no time, and there is no space, there is just energy. And we have contact with that through the intermediate layers, so, if the right channels—if the right connections are established, I don’t see why a piece of matter, a piece of broken glass or and old record can’t make contact through this very high level of reality that has access to everything past and future. I suppose my instruments do retain some sort of memory of me. I know that when I’m working on them I feel (not explicitly, I don’t hear voices in my head or anything) that I’m making a connection with it. The circuit diagram, that is then converted into a circuit board, which then becomes a part of an instrument is something that is a record that I made. So I guess in that sense it is something that is certainly a memory.
