The older view of the nature of heat was that it is a substance, very fine and imponderable indeed, but indestructible, and unchangeable in quantity, which is an essential fundamental property of all matter.
Sentiment: POSITIVE
What appeared to the earlier physicists to be the constant quantity of heat is nothing more than the whole motive power of the motion of heat, which remains constant so long as it is not transformed into other forms of work, or results afresh from them.
Heat cannot be separated from fire, or beauty from The Eternal.
But heat can also be produced by the friction of liquids, in which there could be no question of changes in structure, or of the liberation of latent heat.
If matter cannot be destroyed, cannot be annihilated, it could not have been created. The indestructible must be uncreatable.
At twenty-one, so many things appear solid, permanent, untenable.
The indestructible is one: it is each individual human being and, at the same time, it is common to all, hence the incomparably indivisible union that exists between human beings.
One of the bedrock principles of physics is the conservation of energy. In this universe, energy can be neither created nor destroyed.
My first book is really about heat. That book, for me, was an exploration of heat as ingredient. Why we don't talk about heat as an ingredient, I don't quite understand, because it is the common ingredient to all cooking processes.
At the extreme temperature occurring in the stars, matter can only survive in its most dissociated states. Only simple bodies exist on these incandescent stars.
It ain't the heat, it's the humility.
