Something unknown is doing we don’t know what.
Every body continues in its state of rest, or of uniform motion in a right (straight) line, unless it is compelled to change that state by forces impressed upon it.
It would probably be wiser to nail up over the door of the new quantum theory a notice, “Structural alterations in progress – No admittance except on business”, and particularly to warn the doorkeeper to keep out prying philosophers.
Everything starts somewhere, although many physicists disagree.
Enough of this. Newton forgive me. You found the only way that, in your day, was at all possible for a man of the highest powers of intellect and creativity. The concepts that you created still dominate the way we think in physics, although we now know that they must be replaced by others farther […]
Ordinary language is totally unsuited for expressing what physics really asserts, since the words of everyday life are not sufficiently abstract. Only mathematics and mathematical logic can say as little as the physicist means to say.
The real problem is in the hearts and minds of men. It is not a problem of physics but of ethics. It is easier to denature plutonium than to denature the evil spirit of man.
In science there is only physics, all the rest is stamp collecting.
It should be possible to explain the laws of physics to a barmaid.
If all this damned quantum jumping were really here to stay, I should be sorry I ever got involved with quantum theory.
