Robert Mayer Quotes

The law in question asserts, that the quantity of force which can be brought into action in the whole of Nature is unchangeable, and can neither be increased nor diminished.

A raised weight can produce work, but in doing so it must necessarily sink from its height, and, when it has fallen as deep as it can fall, its gravity remains as before, but it can no longer do work.

A ball will always come to rest halfway down a hill, unless there is sand or water at the bottom.

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

One of the bedrock principles of physics is the conservation of energy. In this universe, energy can be neither created nor destroyed.

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.

In this house, we obey the laws of thermodynamics!

Heat can also be produced by the impact of imperfectly elastic bodies as well as by friction. This is the case, for instance, when we produce fire by striking flint against steel, or when an iron bar is worked for some time by powerful blows of the hammer.

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.

Whenever we warm our hands by the fire, we allow the energy radiated by the fire to quicken up the movements of the atoms of which the hands are composed. When we cool any substance, we check those movements.

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.

Energy is everything. Rubbing happy and sad together creates energy.

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.

Heat energy of uniform temperature [is] the ultimate fate of all energy. The power of sunlight and coal, electric power, water power, winds and tides do the work of the world, and in the end all unite to hasten the merry molecular dance.

The elevator shaft was a kind of heat sink. Hot food was cold by the time it arrived. Cold food got colder. No one knew what would happen to ice cream, but it would probably involve some rewriting of the laws of thermodynamics.

It is sunlight in modified form which turns all the windmills and water wheels and the machinery which they drive. It is the energy derived from coal and petroleum (fossil sunlight) which propels our steam and gas engines, our locomotives and automobiles. ... Food is simply sunlight in cold storage.

It's frightening and unnerving to watch a stone melt.

According to the kinetic theory of gases, the mean kinetic energy of a molecule is a measure of absolute temperature.

Energy Is Conserved.

In order to lift a certain object from the ground, we have to use energy. But then to sustain it at that level, we have to keep on adding energy, or otherwise, the object falls to the ground. It's exactly the same thing with the sound.

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.

In the Marvel universe, vibranium has always been this material that absorbs kinetic energy. And any tiny bit of physics knowledge will tell you that that's really non-Newtonian. You can't just absorb energy, you've gotta change it into something else.

Living fire begets cold, impotent ash.

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.

Energy is a very subtle concept. It is very, very difficult to get right.
