Originally, the burden of proof was on physicists to prove that time travel was possible. Now the burden of proof is on physicists to prove there must be a law forbidding time travel.

There are now over 5,000 medical physicists in the U.S more than 50 times the number in 1958.

Medical physicists work in cooperation with doctors. A few medical physicists devote their time to research and teaching. A few get involved with administrative duties.

Most medical physicists work in the physics of radiation oncology making sure that the desired dose is given to the cancer and the dose to normal tissues are minimized.

The idea would be in my mind - and I know it sounds strange - is that the most important advances in medicine would be made not by new knowledge in molecular biology, because that's exceeding what we can even use. It'll be made by mathematicians, physicists, computer scientists, figuring out a way to get all that information together.

In some sort of crude sense, which no vulgarity, no humor, no overstatement can quite extinguish, the physicists have known sin; and this is a knowledge which they cannot lose.

It was Einstein's dream to discover the grand design of the universe, a single theory that explains everything. However, physicists in Einstein's day hadn't made enough progress in understanding the forces of nature for that to be a realistic goal.

If you want to make big improvements in communication, my advice is - hire physicists, not communications people from normal companies and never believe what advertising companies tell you about 'data' unless you can independently verify it.

Keats mourned that the rainbow, which as a boy had been for him a magic thing, had lost its glory because the physicists had found it resulted merely from the refraction of the sunlight by the raindrops. Yet knowledge of its causation could not spoil the rainbow for me. I am sure that it is not given to man to be omniscient. There will always be something left to know, something to excite the imagination of the poet and those attuned to the great world in which they live (p. 64)

Now and then, teaching may approach poetry, and now and then it?may approach profanity. May I tell you a little story about the great?Einstein? I listened once to Einstein as he talked to a group of?physicists in a party. "Why have all the electrons the same charge?" said he. "Well, why are all the little balls in the goat dung of the same size?"?Why did Einstein say such things? Just to make some snobs to raise?their eyebrows? He was not disinclined to do so, I think. Yet,?probably, it went deeper. I do not think that the overheard remark of?Einstein was quite casual. At any rate, I learnt something from it:?Abstractions are important; use all means to make them more tangible.?Nothing is too good or too bad, too poetical or too trivial to clarify your?abstractions. As Montaigne put it: The truth is such a great thing that?we should not disdain any means that could lead to it. Therefore, if the spirit moves you to be a little poetical, or a little profane, in your class,?do not have the wrong kind of inhibition." - George Polya's Mathematical Discovery, Volume 11, pp 102, 1962.

Physicists have come to realize that mathematics, when used with sufficient care, is a proven pathway to truth.

If you dont love somebody, it gets annoying if they tell you what to do or what to feel. When you love them, you get pleasure from their pleasure nad it makes it easy to serve. I didnt love God because i didnt know God. universe is not effected by time. Light exists outside of time.. It is still a mystery to physicists.

The value today of philosophy to physics seems to me to be something like the value of early nation-states to their peoples. It is only a small exaggeration to say that, until the introduction of the post office, the chief service of nation-states was to protect their peoples from other nation-states. The insights of philosophers have occasionally benefited physicists, but generally in a negative fashion-by protecting them from the preconceptions of other philosophers.

The weapons were conceived and created by a small band of physicists and chemists they remain a cataclysmic threat to the whole of human society and the natural environment.

Among physicists I'm respected I hope.

The way in which mathematicians and physicists and historians talk is quite different and what a physicist means by physical intuition and what a mathematician means by beauty or elegance are things worth thinking about.
