A Quote by David J. C. MacKay
Most of physics is about energy, and physicists understand inefficiencies. I wanted to write a book about our energy options in a neutral, human-accessible form.

One of the most exciting things about dark energy is that it seems to live at the very nexus of two of our most successful theories of physics: quantum mechanics, which explains the physics of the small, and Einstein's Theory of General Relativity, which explains the physics of the large, including gravity.
What is extraordinary about contemporary art is the energy - it has our energy. New energy. Pieces hundreds of years old are beautiful from an aesthetic point of view, but without our modern energy.
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.
If our nation wants to reduce global warming, air pollution and energy instability, we should invest only in the best energy options. Nuclear energy isn't one of them.
Improved energy productivity and renewable energy are both available in abundance—and new policies and technologies are rapidly making them more economically competitive with fossil fuels. In combination, these energy options represent the most robust alternative to the current energy system, capable of providing the diverse array of energy services that a modern economy requires. Given the urgency of the climate problem, that is indeed convenient.
By increasing the use of renewable fuels such as ethanol and bio-diesel, and providing the Department of Energy with a budget to create more energy efficiency options, agriculture can be the backbone of our energy supply as well.
Energy is the master resource, because energy enables us to convert one material into another. As natural scientists continue to learn more about the transformation of materials from one form to another with the aid of energy, energy will be even more important.
At our most elemental, we are not a chemical reaction, but an energetic charge. Human beings and all living things are a coalescence of energy in a field of energy connected to every other thing in the world. This pulsating energy field is the central engine of our being and our consciousness, the alpha and the omega of our existence.
Power is not something we should be afraid of. Power is great, power is energy. And in terms of energy, the most important energy is human spiritual energy and when I say spiritual, I feel like have to be very careful, I don't mean religious, I mean the energy of the mind, the energy that exists within us.
I would like to help people have honest and constructive conversations about energy. We need to understand how much energy our modern lifestyles use, decide how much energy we would like to use in the future, and choose where we will get that energy from.
The ancient intuition that all matter, all "reality," is energy, that all phenomena, including time and space, are mere crystallizations of mind, is an idea with which few physicists have quarreled since the theory of relativity first called into question the separate identities of energy and matter. Today most scientists would agree with the ancient Hindus that nothing exists or is destroyed, things merely change shape or form; that matter is insubstantial in origin, a temporary aggregate of he pervasive energy that animates the electron.
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.
Music is energy, and energy is the single most important form of it in the world. Without energy, there is no life. The only difference between a dead person and a live person is the energy, the electricity flowing inside their system, and that's what makes music.
The unseen energy that was once in Shakespeare or Picasso or Galileo or any human form, is also available to all of us. That is because the spirit energy does not die, it simply changes form.
I'm very moved by chaos theory, and that sense of energy. That quantum physics. We don't really, in Hindu tradition, have a father figure of a God. It's about cosmic energy, a little spark of which is inside every individual as the soul.
You are energy, and energy cannot be created or destroyed. Energy just changes form. And that means You! The true essence of You, the pure energy of You, has always been and always will be. You can never not be.
