Physicists always have a habit of taking the simplest example of any
phenomenon and calling it "physics," leaving the more complicated examples
to become the concern of other fields...
"Science is the belief in the ignorance of experts. "
"I can live with doubt and uncertainty and not knowing. I think it is
much more interesting to live not knowing than to have answers that
might be wrong."
"The first principle is that you must not fool yourself - and you are the
easiest person to fool."
"If we will only allow that, as we progress, we remain unsure, we will
leave opportunities for alternatives. We will not become enthusiastic
for the fact, the knowledge, the absolute truth of the day, but remain
always uncertain... In order to make progress, one must leave the door
to the unknown ajar."
You can know the name of a bird in all the languages of the world, but
when you're finished, you'll know absolutely nothing whatever about the
bird... So let's look at the bird and see what it's doing -- that's what
counts. I learned very early the difference between knowing the name of
something and knowing something.
"We cannot define anything precisely! If we attempt to, we get into that
paralysis of thought that comes to philosophers, who sit opposite each
other, one saying to the other, 'You don't know what you are talking
about!' The second one says 'What do you mean by know? What do you mean by
talking? What do you mean by you?', and so on."
"...far more marvelous is the truth than any artists of the past imagined
it. Why do the poets of the present not speak of it? What men are poets who
can speak of Jupiter if he were a man, but if he is an immense spinning
sphere of methane and ammonia must be silent?"
(On pseudoscience) "...there is one feature I notice that is generally
missing in 'cargo cult science'... It's a kind of scientific integrity, a
principle of scientific thought that corresponds to a kind of utter
honesty -- a kind of leaning over backwards... For example, if you're
doing an experiment, you should report everything that you think might
make it invalid--not only what you think is right about it... Details
that could throw doubt on your interpretation must be given, if you know
them."
"I'd hate to die twice. It's so boring." (last words)
