A Quote by Richard P. Feynman

'Conservation' (the conservation law) means this ... that there is a number, which you can calculate, at one moment-and as nature undergoes its multitude of changes, this number doesn't change. That is, if you calculate again, this quantity, it'll be the same as it was before. An example is the conservation of energy: there's a quantity that you can calculate according to a certain rule, and it comes out the same answer after, no matter what happens, happens.
There are two principles inherent in the very nature of things, recurring in some particular embodiments whatever field we explore - the spirit of change, and the spirit of conservation. There can be nothing real without both. Mere change without conservation is a passage from nothing to nothing. . . . Mere conservation without change cannot conserve. For after all, there is a flux of circumstance, and the freshness of being evaporates under mere repetition.
Knowing how to calculate something is not the same as understanding it. Having a computer to calculate the origin of mass for us may be convincing, but is not satisfying. Fortunately we can understand it too.
There is a conservation of matter and of energy, there may be a conservation of life; or if not of life, of something which transcends life.
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.
The page of my notebook was filled with many messy integrals, but all of a sudden I saw emerge a formula for counting. I had begun to calculate a quantity on the assumption that the result was a real number, but found instead that, in certain units, all the possible answers would be integers. This meant that areas and volumes cannot take any value, but come in multiples of fixed units.
Animal rights can be as extreme as not riding a horse, or not wearing leather, not having a pet at all. Animal welfare advocates are preventing the suffering of animals. And then there's conservation and species conservation and what conservation biologists do.
Revolution is everywhere, in everything. It is infinite. There is no final revolution, no final number. The social revolution is only one of an infinite number of numbers: the law of revolution is not a social law, but an immeasurably greater one. It is a cosmic, universal law - like the laws of the conservation of energy and of the dissipation of energy (entropy).
I never calculate. That is why those who do, calculate so much less accurately than I.
I think that we have to be constantly asking ourselves, 'How do we calculate the risk?' And sometimes we don't calculate it correctly; we either overstate it or understate it.
Leibniz mapped the principles concerning the conservation of energy, but nobody has yet scientifically diagrammed the conservation of emotion - have they? How is this subsumed pain vented? Is it released in my art? I hope so, but I also suspect that it's emitted in my sleep.
I'm a good example of wanting to apologize only for my precise share of a problem--as I calculate it, of course--and I expect my husband Steve to apologize for his share, also as I calculate it. Since we're not always of one mind on the math, it can lead to the theater of the absurd.
We must not risk defunding environmental conservation programs, which is why Congress should reauthorize the Land and Water Conservation Fund to preserve our natural resources.
It takes many years to become proficient in energy conservation. But it is something that happens. You get continually stronger. You see your attention field is far different than it ever was before.
No more fiction, for now we calculate; but that we may calculate, we had to make fiction first.
From a conservation issue alone, you'd have to say there are too many badgers. A bigger growth in the badger population is not good for the balance of conservation anyway.
We may lay it down as an incontestible axiom, that, in all the operations of art and nature, nothing is created; an equal quantity of matter exists both before and after the experiment; the quality and quantity of the elements remain precisely the same; and nothing takes place beyond changes and modifications in the combination of these elements. Upon this principle the whole art of performing chemical experiments depends: We must always suppose an exact equality between the elements of the body examined and those of the products of its analysis.
