Nonsense. Space is blue and birds fly through it.
The 'path' comes into existence only when we observe it.
Science clears the fields on which technology can build.
The reality we can put into words is never reality itself.
The one who insists on never uttering an error must remain silent.
Every tool carries with it the spirit by which it has been created.
Only a few know, how much one must know to know how little one knows.
There are things that are so serious that you can only joke about them.
My mind was formed by studying philosophy, Plato and that sort of thing.
It will never be possible by pure reason to arrive at some absolute truth.
Not only is the Universe stranger than we think, it is stranger than we can think.
The more closely you look at one thing, the less closely can you see something else.
Certainly, in the course of time, the splendid things will separate from the hateful.
What we observe is not nature itself, but nature exposed to our method of questioning.
...separation of the observer from the phenomenon to be observed is no longer possible.
Every word or concept, clear as it may seem to be, has only a limited range of applicability.
A consistent pursuit of classical physics forces a transformation in the very heart of that physics.
Every experiment destroys some of the knowledge of the system which was obtained by previous experiments.
The more precise the measurement of position, the more imprecise the measurement of momentum, and vice versa.
Thus, the more precisely the position is determined, the less precisely the momentum is known, and conversely.
"Uncertainty" is NOT "I don't know." It is "I can't know." "I am uncertain" does not mean "I could be certain."
An expert is someone who knows some of the worst mistakes that can be made in his subject and how to avoid them.
In 1924, I became a Dozent in Gottingen and worked out the quantum mechanics during a holiday stay on Heligoland.
If we made atomic bombs, we would bring about a terrible change in the world. Who knows what would happen from this?
The basic idea is to shove all fundamental difficulties onto the neutron and to do quantum mechanics in the nucleus.
I think that the discovery of antimatter was perhaps the biggest jump of all the big jumps in physics in our century.
Natural science, does not simply describe and explain nature; it is part of the interplay between nature and ourselves
Natural science, does not simply describe and explain nature; it is part of the interplay between nature and ourselves.
The Same organizing forces that have shaped nature in all her forms are also responsible for the structure of our minds.
Even for the physicist the description in plain language will be a criterion of the degree of understanding that has been reached.
Nature allows only experimental situations to occur which can be described within the framework of the formalism of quantum mechanics
Bohr's influence on the physics and the physicists of our century was stronger than that of anyone else, even than that of Albert Einstein.
After the conversations about Indian philosophy, some of the ideas of Quantum Physics that had seemed so crazy suddenly made much more sense.
I had imagined doing nuclear physics and cosmic ray work in greater style in peace time. To do modern physics in a small way is of no use of all.
When I meet God, I am going to ask him two questions: Why relativity ? And why turbulence ? I really believe he will have an answer for the first.
The existing scientific concepts cover always only a very limited part of reality, and the other part that has not yet been understood is infinite.
[T]he atoms or elementary particles themselves are not real; they form a world of potentialities or possibilities rather than one of things or facts.
I believe that the existence of the classical "path" can be pregnantly formulated as follows: The "path" comes into existence only when we observe it.
In general, scientific progress calls for no more than the absorption and elaboration of new ideas- and this is a call most scientists are happy to heed.
We will have to abandon the philosophy of Democritus and the concept of elementary particles. We should accept instead the concept of elementary symmetries.
Whether we electrons, light quanta, benzol molecules, or stones, we shall always come up against these two characteristics, the corpuscular and the undular.
By getting to smaller and smaller units, we do not come to fundamental or indivisible units. But we do come to a point where further division has no meaning.
Whenever we proceed from the known to the unkown we may hope to understand, but we may have to learn at the same time a new meaning of the word 'understanding'
Quantum theory provides us with a striking illustration of the fact that we can fully understand a connection though we can only speak of it in images and parables.
The problems of language here are really serious. We wish to speak in some way about the structure of the atoms. But we cannot speak about atoms in ordinary language.
There is a fundamental error in separating the parts from the whole, the mistake of atomizing what should not be atomized. Unity and complementarity constitute reality.
Whoever dedicates his life to searching out particular connections of nature will spontaneously be confronted with the question how they harmoniously fit into the whole.
