Hermann von Helmholtz Quotes

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

Energy Is Conserved.

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.

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.

Energy can't be destroyed, only converted into something different. So when a person dies, where does that energy go?

There is no energy in matter other than that received from the environment

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°.

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.

Energy is a concept that has been coined by physicists. There is no observable thing known as energy anywhere.

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.

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

The law of conservation of energy tells us we can't get something for nothing, but we refuse to believe it.

We're electrical items and when we die the electricity goes somewhere else. When we die our energy goes into the galaxy.

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.

Energy can't be created or destroyed, and energy flows. It must be in a direction, with some kind of internal, emotive, spiritual direction. It must have some effect somewhere.

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.

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

Energy is the inherent effort of every multiplicity to become unity.

Our energy is in proportion to the resistance it meets.

Everything is energy. All matter is energy. Energy cannot be created or destroyed. It is the cause and affect of itself. It is evenly present in all places, at all times. Energy is in constant motion and never rests. It is forever moving from one form to another. Energy follows thought.

When a body acts upon another one, it is always immediately or through some intermediate body; this intermediate body is in general what one calls a machine.

Local order in parts of the universe is always possible at the expense of heat and disorder dissipated to the external environment. The human body is one example: we take in energy from our environment to build up complex molecules that help power our bodies, and, in doing so, we release heat to the world around us.
