Swami Vivekananda Quotes

The total quantity of all the forces capable of work in the whole universe remains eternal and unchanged throughout all their changes. All change in nature amounts to this, that force can change its form and locality, without its quantity being changed. The universe possesses, once for all, a store of force which is not altered by any change of phenomena, can neither be increased nor diminished, and which maintains any change which takes place on it.

Nothing can create something all the time due to the laws of quantum mechanics, and it's - it's fascinatingly interesting.

It is just physics - who can argue with Newton and the first law of thermodynamics?

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

Before the discovery of quantum mechanics, the framework of physics was this: If you tell me how things are now, I can then use the laws of physics to calculate, and hence predict, how things will be later.

The universe is composed of matter, and, as a system, is sustained by motion. Motion is not a property of matter, and without this motion the solar system could not exist.

There is nothing more certain in nature than that it is impossible for any body to be utterly annihilated.

I know that nothing is destructible; things merely change forms.

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

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

Physics is based on the assumption that certain fundamental features of nature are constant.

Acceleration is finite, I think according to some laws of physics.

Pick a flower on Earth and you move the farthest star.

You may hate gravity, but gravity doesn't care.

There is no science in this world like physics. Nothing comes close to the precision with which physics enables you to understand the world around you. It's the laws of physics that allow us to say exactly what time the sun is going to rise. What time the eclipse is going to begin. What time the eclipse is going to end.

Man is simply the best chance we know of that matter has had of providing itself with information about itself.

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.

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.

The same law takes place in a system, consisting of many bodies, as in one single body, with regard to their persevering in their state of motion or of rest. For the progressive motion, whether of one single body or of a whole system of bodies, is always to be estimated from the motion of the center of gravity.

The foregoing considerations lead us to the very important conclusion, that matter is essentially force, and nothing but force; that matter, as popularly understood, does not exist, and is, in fact, philosophically inconceivable.

When you buy a jacket, you pick the size to ensure it fits. Similarly, we live in a universe in which the amount of dark energy fits our biological make-up. If the amount of dark energy were substantially different from what we've measured, the environmental conditions would be inhospitable to our form of life.

All great results in our universe are founded in motions and forces the most minute.

Every description of natural processes must be based on ideas which have been introduced and defined by the classical theory.

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.
