A Quote by James Prescott Joule

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.
The earth in its rapid motion round the sun possesses a degree of living force so vast that, if turned into the equivalent of heat, its temperature would be rendered at least one thousand times greater than that of red-hot iron, and the globe on which we tread would in all probability be rendered equal in brightness to the sun itself.
The hypothesis of molecular vortices is defined to be that which assumes - that each atom of matter consists of a nucleus or central point enveloped by an elastic atmosphere, which is retained in its position by attractive forces, and that the elasticity due to heat arises from the centrifugal force of those atmospheres revolving or oscillating about their nuclei or central points.According to this hypothesis, quantity of heat is the vis viva of the molecular revolutions or oscillations.
Electrical force is defined as something which causes motion of electrical charge; an electrical charge is something which exerts electric force.
I am a leader, so 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.

For the first time there was constructed with this machine [locomotive engine] a self-acting mechanism in which the interplay of forces took shape transparently enough to discern the connection between the heat generated and the motion produced. The great puzzle of the vital force was also immediately solved for the physiologist in that it became evident that it is more than a mere poetic comparison when one conceives of the coal as the food of the locomotive and the combustion as the basis for its life.
The libertarian approach is a very symmetrical one: the non-aggression principle does not rule out force, but only the initiation of force. In other words, you are permitted to use force only in response to some else's use of force. If they do not use force you may not use force yourself. There is a symmetry here: force for force, but no force if no force was used.
Our real work is prayer. What good is the cold iron of our frantic little efforts unless first we heat it in the furnace of our prayer? Only heat will diffuse heat.
That small word "Force," they make a barber's block, Ready to put on Meanings most strange and various, fit to shock Pupils of Newton.... The phrases of last century in this Linger to play tricks- Vis viva and Vis Mortua and Vis Acceleratrix:- Those long-nebbed words that to our text books still Cling by their titles, And from them creep, as entozoa will, Into our vitals. But see! Tait writes in lucid symbols clear One small equation; And Force becomes of Energy a mere Space-variation.
Heat may be generated and destroyed by certain processes, and this shows that heat is not a substance.
Unfortunately, I'm heat intolerant. I tend not to go in heat, I avoid the bath, I have lukewarm showers - and now I am throwing myself into the heat of Dubai and trying to run.
One cool judgment is worth a thousand hasty councils. The thing to do is to supply light and not heat. Ay any rate, if it is heat it ought to be white heat and not sputter, because sputtering heat is apt to spread the fire. There ought, if there is any heat at all, to be that warmth of the heart which makes every man thrust aside his own personal feeling, his own personal interest, and take thought of the welfare and benefit of others.
Architects in urban planning are talking about this but they're not talking about it yet I don't think at that level that [Buckminster] Fuller is talking about when he talked about putting a dome over Manhattan, which is to say an attempt at integrating all of these different technologies in a way that makes for a city that, without having an actual dome, thermodynamically manages the heat flow for that urban environment and therefore makes it so that it is a highly efficient machine for a living or a dwelling machine as he would have preferred in terms of thermodynamically optimizing it.
Mighty is the force of motherhood! It transforms all things by its vital heat.
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.
What I have related is sufficient for establishing the main principle, namely, that the heat which disappears in the conversion of water into vapour, is not lost, but is retained in vapour, and indicated by its expansive form, although it does not affect the thermometer. This heat emerges again from this vapour when it becomes water, and recovers its former quality of affecting the thermometer; in short, it appears again as the cause of heat and expansion.
