No, no, you're not thinking;

It is wrong to think that the task of physics is to find out how Nature is. 

Physics concerns what we say about Nature.

Every sentence I utter 

must be understood 

not as an affirmation, 

but as a question.

The opposite of a fact is falsehood, 

but the opposite of one profound truth 

may very well be 

another profound truth.

The best weapon of a dictatorship is secrecy, 

but the best weapon of a democracy should be 

the weapon of openness.

A physicist is just an atom's way of looking at itself.

When it comes to atoms, 

language can be used only as in poetry. 

The poet, too, is not nearly so concerned with describing facts 

as with creating images.

It is the hallmark of any deep truth 

that its negation is also a deep truth.

How wonderful that we have met with a paradox. 

Now we have some hope of making progress.

There are some things so serious 

you have to laugh at them.

Every great and deep difficulty bears in itself it’s own solution. 

It forces us to change our thinking in order to find it.

Opposites are complementary.

Everything we call real is made of things that cannot be regarded as real.

It is wrong to think that the task of physics is to find out how Nature is.
