Therefore psychologically we must keep all the theories in our heads, and every theoretical physicist who is any good knows six or seven different theoretical representations for exactly the same physics.

More quotes by Richard P. Feynman
In physics the truth is rarely perfectly clear, and that is certainly universally the case in human affairs. Hence, what is not surrounded by uncertainty cannot be the truth.
Richard P. Feynman
What did you ASK at school today?
Richard P. Feynman
When things are going well, something will go wrong. / When things just can't get any worse, they will. / Anytime things appear to be going better, you have overlooked something.
Richard P. Feynman
Only realistic flight schedules should be proposed, schedules that have a reasonable chance of being met. If in this way the government would not support them, then so be it. NASA owes it to the citizens from whom it asks support to be frank, honest, and informative.
Richard P. Feynman
I think we can safely assume that no one understands quantum mechanics.
Richard P. Feynman
One does not, by knowing all the physical laws as we know them today, immediately obtain an understanding of anything much. I love only nature, and I hate mathematicians.
Richard P. Feynman
I wonder why. I wonder why. I wonder why I wonder.
Richard P. Feynman
Agnostic for me would be trying to weasel out and sound a little nicer than I am about this.
Richard P. Feynman
We can deduce, often, from one part of physics like the law of gravitation, a principle which turns out to be much more valid than the derivation.
Richard P. Feynman
It is important to realize that in physics today, we have no knowledge of what energy is
Richard P. Feynman
The game I play is a very interesting one. It's imagination in a straightjacket, which is this: that it has to agree with the known laws of physics. ... It requires imagination to think of what's possible, and then it requires an analysis back, checking to see whether it fits, whether its allowed, according to what's known, okay?
Richard P. Feynman
Nature does not care what we call it, she just keeps on doing it.
Richard P. Feynman
We've learned from experience that the truth will out.
Richard P. Feynman
Science is a way of trying not to fool yourself.
Richard P. Feynman
Physicists like to think that all you have to do is say, these are the conditions, now what happens next?
Richard P. Feynman
Victory usually goes to those green enough to underestimate the monumental hurdles they are facing.
Richard P. Feynman
If you have any talent, or any occupation that delights you, do it, and do it to the hilt. Don't ask why, or what difficulties you may get into.
Richard P. Feynman
The electron is a theory. But the theory is so good we can almost consider them real.
Richard P. Feynman
The fact that you are not sure means that it is possible that there is another way someday.
Richard P. Feynman
Outside of their particular area of expertise scientists are just as dumb as the next person.
Richard P. Feynman
