James Prescott Joule Quotes

If you assume that it was a valid experiment, then its disintegration reveals a very substantial part of what has been found since then, including the fact that you can get heat generation at high temperature.

Last year, I made a refrigerator in my basement. And I needed to because I needed to figure how - you know there is no such thing as 'cold.' There is only less heat.

When I was studying at Purdue, we learned our thermodynamics from an antique steam engine. When I went back in 1964, I found the laboratories packed with the most modern equipment for the study of thermodynamics, some of which had been built by the students themselves.

Weather systems are natural heat engines, and like all other heat engines, both natural and artificial, they are driven not by temperature per se, but by differences in temperature between one location and another.

The laws of thermodynamic s are such that if the water is getting warmer - and I believe it is - the energy of the weather is going to go up.

Still all the day the iron wheels go onward, Grinding life down from its mark.

The fall of a given weight from a height of around 365 meters corresponds to the heating of an equal weight of water from 0° to 1°.

Although mechanical energy is indestructible, there is a universal tendency to its dissipation, which produces throughout the system a gradual augmentation and diffusion of heat, cessation of motion and exhaustion of the potential energy of the material Universe

James Watt was equally distinguished as a natural philosopher and chemist; his inventions demonstrate his profound knowledge of those sciences, and that peculiar characteristic of genius - the union of them for practical application.

Whatever is not an energy source, is an energy sink.

The weird thing about the arrow of time is that it's not to be found in the underlying laws of physics. It's not there. So it's a feature of the universe we see, but not a feature of the laws of the individual particles. So the arrow of time is built on top of whatever local laws of physics apply.

Something can be real - actually existing, not merely illusory - and yet not be fundamental. Scientists used to think that heat, for example, was a fluidlike substance called 'caloric' that flowed from hot objects to colder ones.

If we assume there is no maximum possible entropy for the universe, then any state can be a state of low entropy.

[Referring to Fourier's mathematical theory of the conduction of heat] ... Fourier's great mathematical poem.

In speaking of the Energy of the field, however, I wish to be understood literally. All energy is the same as mechanical energy, whether it exists in the form of motion or in that of elasticity, or in any other form. The energy in electromagnetic phenomena is mechanical energy.

Thanks to the discoveries of astronomers in the twentieth century, we now know that the heat death is a myth. The heat death can never happen, and there is no paradox.

Energy is the only universal currency: one of its many forms must be transformed to another in order for stars to shine, planets to rotate, plants to grow, and civilizations to evolve.

Cost is always an object - the second law of thermodynamics sees to that

You cannot make a windmill go with a pair of bellows.

Energy is the measure of that which passes from one atom to another in the course of their transformations. A unifying power, then, but also, because the atom appears to become enriched or exhausted in the course of the exchange, the expression of structure.

Is not Fire a Body heated so hot as to emit Light copiously? For what else is a red hot Iron than Fire? And what else is a burning Coal than red hot Wood?

In the eighteenth century it was often convenient to regard man as a clockwork automaton. In the nineteenth century, with Newtonian physics pretty well assimilated and a lot of work in thermodynamics going on, man was looked on as a heat engine, about 40 per cent efficient. Now in the twentieth century, with nuclear and subatomic physics a going thing, man had become something which absorbs X-rays, gamma rays and neutrons.

There is nothing like a doorbell to precipitate the potential into the kinetic.

The paynefull smith, with force of fervent heat, The hardest yron soone doth mollify, That with his heavy sledge he can it beat, And fashion it to what he it list apply.

Every tiny molecule of Ash is in motion with my heat I am such a Lunatic that I am free even in Jail.
