There is a time for scientists and movie stars and those who have flown the atlantic to restrain their opinions lest they be taken more seriously than they should be.
By having simplified what is known, physicists have been led into realms which as yet are anything but simple. That at some time, they, too, will appear as simple consequences of a theory of which no one has yet dreamed is not a statement of fact.It is a statement of faith.
Society's emissions of carbon dioxide may or may not turn out to have something significant to do with global warming-the jury is still out.
There is no case where ignorance should be preferred to knowledge - especially if the knowledge is terrible.
It is often claimed that knowledge multiplies so rapidly that nobody can follow it. I believe this is incorrect. At least in science it is not true. The main purpose of science is simplicity and as we understand more things, everything is becoming simpler. This, of course, goes contrary to what everyone accepts.
I am guilty of the great crime of optimism.
I believe in good. It is an ephemeral and elusive quality. It is the center of my beliefs, but it cannot be strengthened by talking about it.
I think that intellectuals who end up in hell will have to read page proofs and check indexes there.
Secrecy in science does not work. Withholding information does more damage to us than to our competitors.
One may say that predictions are dangerous particularly for the future. If the danger involved in a prediction is not incurred, no consequence follows and the uncertainty principle is not violated.
Today's science is tomorrow's technology.
In the theater you create a moment, but in that moment, there is a touch, a twinkle of eternity. And not just eternity, but community. . . . That connection is a sense of life for me.
The scientist is not responsible for the laws of nature. It is his job to find out how these laws operate. It is the scientist's job to find the ways in which these laws can serve the human will. However, it is not the scientist's job to determine whether a hydrogen bomb should be constructed, whether it should be used, or how it should be used. This responsibility rests with the American people and with their chosen representatives.
[Chemistry] laboratory work was my first challenge. ... I still carry the scars of my first discovery-that test-tubes are fragile.
A state-of-the-art calculation requires 100 hours of CPU time on the state-of-the-art computer, independent of the decade.
Really exotic methods of propulsion . . . will have to be devised to get there. How it will be done, I do not know. Whether it will be done, I am not quite certain. But I would bet it can be done.
Today, nothing is unusual about a scientific discovery's being followed soon after by a technical application: The discovery of electrons led to electronics; fission led to nuclear energy. But before the 1880's, science played almost no role in the advances of technology. For example, James Watt developed the first efficient steam engine long before science established the equivalence between mechanical heat and energy.
I claim that relativity and the rest of modern physics is not complicated. It can be explained very simply. It is only unusual or, put another way, it is contrary to common sense.
My experience has been in a short 77 years that in the end when you fight for a desperate cause and have good reasons to fight, you usually win.
U.S. has lost a battle more important and greater than Pearl Harbor.
I tried to contribute to the defeat of the Soviets. If I contributed 1%, it is 1% of something enormous.
In the history of physics, there have been three great revolutions in thought that first seemed absurd yet proved to be true. The first proposed that the earth, instead of being stationary, was moving around at a great and variable speed in a universe that is much bigger than it appears to our immediate perception. That proposal, I believe, was first made by Aristarchos two millenia ago ... Remarkably enough, the name Aristarchos in Greek means best beginning.
In our educational institutions applied science may almost be described as a "no-man's land."
Knowing he [Bob Serber] was going to the [first atom bomb] test, I asked him how he planned to deal with the danger of rattlesnakes. He said, 'I'll take along a bottle of whiskey.' … I ended by asking, 'What would you do about those possibilities [of what unknown phenomena might cause a nuclear explosion to propagate in the atmosphere]?' Bob replied, 'Take a second bottle of whiskey.'
Could we have avoided the tragedy of Hiroshima? Could we have started the atomic age with clean hands? No one knows. No one can find out.
