Energy

Feynman, Richard Leighton, R.B. Sands, M.

There is a fact, or if you wish, a law governing all natural phenomena that are known to date. There is no known exception to this law—it is exact as far as we know. The law is called the conservation of energy. It states that there is a certain quantity, which we call energy, that does not change in the manifold changes which nature undergoes. That is a most abstract idea, because it is a mathematical principle; it says that there is a numerical quantity which does not change when something happens.

It is important to realize that in physics today, we have no knowledge of what energy is.

Huxley, Julian

I am Energy. Sublime and meaningless Energy. I stream in floods across the empty ocean Of Space, where island-universes float, Each like a little lonely boat.

Meyerson, Emile

Energy is really only an integral; now, what we want to have is a substantial definition, like that of Leibniz, and this demand is justifiable to a certain degree, since our very conviction of the conservation of energy rests in great part on this foundation...And so the manuals of physics contain really two discordant definitions of energy, the first which is verbal, intelligible, capable of establishing our conviction, and false; and the second which is mathematical, exact, but lacking verbal expression.

The innumerable members of our galaxy assure us, however, that though the stars may be evaporating, so to speak, like the dew, their energies will in some way be integrated again.

Astronomy Chapter XV (p. 471)

Soddy, Frederick

Energy, someone may say, is a mere abstraction, a mere term, not a real thing. As you will. In this, as in many another respects, it is like an abstraction no one would deny reality to, and that abstraction is wealth. Wealth is the power of purchasing, as energy is the power of working. I cannot show you energy, only its effects. ..Abstraction or not, energy is as real as wealth—I am not sure that they are not two aspects of the same thing.

Don't bother me, I'm busy conserving energy, momentum, and angular momentum.
