Matter and Energy Quotes

I think I always wanted to go into physics. What always fascinated me about science was the desire to understand what underlies it all, and I think physics is basically the study of that.

It would be a poor thing to be an atom in a universe without physicists, and physicists are made of atoms. A physicist is an atom's way of knowing about atoms.

I thought I should study physics because it's fundamental to all science.

A physicist is just an atom's way of looking at itself.

The stars are matter, we're matter, but it doesn't matter.

The nature of matter, or body considered in general, consists not in its being something which is hard or heavy or coloured, or which affects the senses in any way, but simply in its being something which is extended in length, breadth and depth.

Nothing puzzles me more than the time and space; and yet nothing troubles me less.

Theory may be deliberate, as in a chapter on chemistry, or it may be second nature, as in the immemorial doctrine of ordinary enduring middle-sized physical objects.

Fundamental physics is like an art more or less. It's completely non-practical, and you can't use it for anything. But it's about the universe and how the world came into being. It's very remote from your daily life and mine, and yet it defines us as human beings.

It is easy to make out three areas where scientists will be concentrating their efforts in the coming decades. One is in physics, where leading theorists are striving, with the help of experimentalists, to devise a single mathematical theory that embraces all the basic phenomena of matter and energy. The other two are in biology. Biologists-and the rest of us too-would like to know how the brain works and how a single cell, the fertilized egg cell, develops into an entire organism

We account for all the matter and energy that we're familiar with, measure up how much gravity it should have, it's one-sixth of the gravity that's actually operating on the universe. We call that dark matter. It really should be called dark gravity. We don't know what that is.

Just as there are laws of Conservation of Matter and Energy, so there are in fact Laws of Conservation of Pain and Joy. Neither can ever be created or destroyed. But one can be converted into the other.

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

Physics is nothing but the ABC's. Nature is an equation with an unknown, a Hebrew word which is written only with consonants to which reason has to add the dots.

Physics is, hopefully, simple. Physicists are not.

From this time on, the universe is built up into an aggregate of permanent objects connected by causal relations that are independent of the subject and are placed in objective space and time.
