A Quote by Hermann von Helmholtz
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.

In all cases where work is produced by heat, a quantity of heat proportional to the work done is expended; and inversely, by the expenditure of a like quantity of work, the same amount of heat may be produced.
The effects of heat are subject to constant laws which cannot be discovered without the aid of mathematical analysis. The object of the theory is to demonstrate these laws; it reduces all physical researches on the propagation of heat, to problems of the integral calculus, whose elements are given by experiment. No subject has more extensive relations with the progress of industry and the natural sciences; for the action of heat is always present, it influences the processes of the arts, and occurs in all the phenomena of the universe.
Heat may be considered, either in respect of its quantity, or of its intensity. Thus two lbs. of water, equally heated, must contain double the quantity that one of them does, though the thermometer applied to them separately, or together, stands at precisely the same point, because it requires double the time to heat two lbs. as it does to heat one.
But we must also look at renewable heat technology. More combined heat and power schemes, putting waste heat to better use. More district heating schemes. And more electric air and ground-source heat pumps, drawing warmth from the outside world to heat the indoors. Better insulation, smarter homes, and more efficient heating can help us cut our energy demand.
Constant companionship is not enjoyable, any more than constant eating. We sit too long at the table of friendship, when we outsit our appetites for each other's thoughts.
You have to be uncompromised in your level of commitment to whatever you are doing, or it can disappear as fast as it appeared... Excellence isn't a one-week or one-year ideal. It's a constant. There will be days when you don't feel on top of your game, or meetings in which you aren't at your best, but your commitment remains constant. No compromises.
The physiological combustion theory takes as its starting point the fundamental principle that the amount of heat that arises from the combustion of a given substance is an invariable quantity-i.e., one independent of the circumstances accompanying the combustion-from which it is more specifically concluded that the chemical effect of the combustible materials undergoes no quantitative change even as a result of the vital process, or that the living organism, with all its mysteries and marvels, is not capable of generating heat out of nothing.
I am a leader. Leaders always get heat. They're always going against the grain. Jimi Hendrix got heat; Bob Marley got heat; Miles Davis got heat. Every great artist got heat. Heat means you're doing something right.

In Nature nothing remains constant. Everything is in a perpetual state of transformation, motion and change.
And by the influence of heat, light, and electrical powers, there is a constant series of changes; matter assumes new forms, the destruction of one order of beings tends to the conservation of another; solution and consolidation, decay and renovation, are connected; and whilst the parts of the system continue in a state of fluctuation and change, the order and harmony of the whole remain unalterable.
Gases are distinguished from other forms of matter, not only by their power of indefinite expansion so as to fill any vessel, however large, and by the great effect heat has in dilating them, but by the uniformity and simplicity of the laws which regulate these changes.
The heart in man signifieth the heat or the element of fire, and it is also the heat; for the heat in the whole body hath its original in the heart.
Don't speak if you don't have to about trivia. The time for joking comes because of the trust, and you have to earn the trust. So, I don't alibi for anything, and I'll take the heat. That's the other thing. Don't let them take the heat. We take the heat.
The most convincing proof of the conversion of heat into living force [vis viva] has been derived from my experiments with the electro-magnetic engine, a machine composed of magnets and bars of iron set in motion by an electrical battery. I have proved by actual experiment that, in exact proportion to the force with which this machine works, heat is abstracted from the electrical battery. You see, therefore, that living force may be converted into heat, and that heat may be converted into living force, or its equivalent attraction through space.
If you do a quantity challenge, the problem you'd face would be a starchy challenge. If it has a lot of potatoes, a lot of bread or fried elements, that's difficult. With heat challenges, challenges that use the whole pepper are much, much easier than ones that use pepper extract. That's concentrated, and also devoid of flavour. It's just heat.
