The only thing that interests the physicist is finding out on what assumptions a framework of things can be constructed which will enable us to know how to use them mechanically. Physics, as I have said on another occasion, is the technique of techniques and the ars combinatoria for fabricating machines. It is a knowledge which has scarcely anything to do with comprehension.

Physical objects are conceptually imported into the situation as convenient intermediaries not by definition in terms of experience, but simply as irreducible posits comparable, epistemologically, to the Gods of Homer . . . For my part I do, qua lay physicist, believe in physical objects and not in Homer's Gods; and I consider it a scientific error to believe otherwise. But in point of epistemological footing, the physical objects and the Gods differ only in degree and not in kind. Both sorts of entities enter our conceptions only as cultural posits.

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.

I think it's science and physics are just starting to learn from all these experiments. These experiments have been carried out hundreds and hundreds of times in all sorts of ways that no physicist really questions the end point. I think that these experiments are very clearly telling us that consciousness is limitless and the ultimate reality.

As a theoretical physicist I feel at once proud and humble at the thought of the illustrious figures that have preceded me here to receive the greatest of all honors in science the Nobel prize.

I'm a geophysicist and all my earth science books when I was a student I had to give the wrong answer to get an A. We used to ridicule continental drift. It was something we laughed at. We learned of Marshall Kay's geosynclinal cycle which is a bunch of crap.

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

I am sure that I have been much more useful to society as a medical physicist.

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 growth of technology is such that it is not possible today for a nuclear physicist to switch into medical physics without training. The field is now much more technical. More training is needed to do the job.

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.

Among physicists I'm respected I hope.

I get heartfelt thanks from all kinds of people. Today I heard from a waitress in Georgia who has lost her job and is trying to figure out how her local bank can change the terms on her credit card and I heard from a physicist at a major research university who wants to explain a better theory of financial stress tests.

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.
