Physics is like sex: sure, it may give some practical results, but that's not why we do it.
-
If you keep proving stuff that others have done, getting confidence, increasing the complexities of your solutions - for the fun of it - then one day you'll turn around and discover that nobody actually did that one! And that's the way to become a computer scientist.
-
As revealed by physics, the truth is so remarkable, so amazing!
-
You can’t say A is made of B or vice versa. All mass is interaction.
-
If you can find any other view of the world which agrees over the entire range where things have already been observed, but disagrees somewhere else, you have made a great discovery.
-
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.
-
Thus we can get the correct answer for the probability of partial reflection by imagining (falsely) that all reflection comes from only the front and back surfaces. In this intuitively easy analysis, the 'front surface' and 'back surface' arrows are mathematical constructions that give us the right answer, whereas .... a more accurate representation of what is really going on: partial reflection is the scattering of light by electrons inside the glass.
-
We've learned from experience that the truth will out.
-
Know your place in the world and evaluate yourself fairly, not in terms of the naïve ideals of your own youth, nor in terms of what you erroneously imagine your teacher's ideals are.

-
If you can't explain something to a first year student, then you haven't really understood .
-
What Do You Care What Other People Think?
-
Our freedom to doubt was born out of a struggle against authority in the early days of science. It was a very deep and strong struggle: permit us to question - to doubt - to not be sure. I think that it is important that we do not forget this struggle and thus perhaps lose what we have gained.
-
Do not read so much, look about you and think of what you see there.
-
Start out understanding religion by saying everything is possibly wrong... As soon as you do that, you start sliding down an edge which is hard to recover from.
-
The Quantum Universe has a quotation from me in every chapter - but it's a damn good book anyway.
-
Of course, you only live one life, and you make all your mistakes, and learn what not to do, and that's the end of you.
-

-
People often think I'm a faker, but I'm usually honest, in a certain way--in such a way that often nobody believes me!
-
No problem is too small or too trivial if we can really do something about it.
-
It appears that there are enormous differences of opinion as to the probability of a failure with loss of vehicle and of human life. The estimates range from roughly 1 in 100 to 1 in 100,000. The higher figures come from the working engineers, and the very low figures from management.
-
I learned very early the difference between knowing the name of something and knowing something.
