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.

Our science has become terrible our research dangerous our findings deadly. We physicists have to make peace with reality. Reality is not as strong as we are. We will ruin reality.

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.

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.

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.
