If you think you understand quantum mechanics, you don't understand quantum mechanics.— Richard P. Feynman
Most Powerful Quantum Mechanical quotations
If quantum mechanics hasn't profoundly shocked you, you haven't understood it yet.
[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.
Common sense has no place in Quantum Mechanics.
When forced to summarize the general theory of relativity in one sentence: Time and space and gravitation have no separate existence from matter.
Solipsism may be logically consistent with present Quantum Mechanics, Monism in the sense of Materialism is not.
I count Maxwell and Einstein, Eddington and Dirac, among "real" mathematicians.
The great modern achievements of applied mathematics have been in relativity and quantum mechanics, and these subjects are at present at any rate, almost as "useless" as the theory of numbers.
I am going to tell you what nature behaves like.
If you will simply admit that maybe she does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you can possibly avoid it, 'But how can it be like that?' ...Nobody knows how it can be like that.
It was not possible to formulate the laws of quantum mechanics in a fully consistent way without reference to the consciousness.
When the province of physical theory was extended to encompass microscopic phenomena through the creation of quantum mechanics, the concept of consciousness came to the fore again. It was not possible to formulate the laws of quantum mechanics in a fully consistent way without reference to the consciousness.
When things get tough, there are two things that make life worth living: Mozart, and quantum mechanics
If all people learned to think in the non Aristotelian manner of quantum mechanics, the world would change so radically that most of what we call "stupidity" and even a great deal of what we consider "insanity" might disappear, and the "intractable" problems of war, poverty and injustice would suddenly seem a great deal closer to solution.
When you think about the complexity of our natural world - plants using quantum mechanics for photosynthesis, for example - a smartphone begins to look like a pretty dumb object.
If [quantum theory] is correct, it signifies the end of physics as a science.
[T]he laws of quantum mechanics itself cannot be formulated .
.. without recourse to the concept of consciousness.
[The Many-worlds interpretation is the] only completely coherent approach to explaining both the contents of quantum mechanics and the appearance of the world.
Our intellect does not draw its laws from nature, but it imposes its laws upon nature.
If you start any large theory, such as quantum mechanics, plate tectonics, evolution, it takes about 40 years for mainstream science to come around. Gaia has been going for only 30 years or so.
Niels Bohr brainwashed a whole generation of theorists into thinking that the job (interpreting quantum theory) was done 50 years ago.
The great ocean of truth lay all undiscovered before me.
Nothing can create something all the time due to the laws of quantum mechanics, and it's - it's fascinatingly interesting.
When it comes to atoms, language can be used only as in poetry.
Quantum mechanics makes absolutely no sense.
The difference between science and religion is that the former wishes to get rid of mysteries whereas the latter worships them.
Quantum mechanics as it stands would be perfect if we didn’t have the quantum-gravity issue and a few other very deep fundamental problems.
Quantum Mechanics is different. Its weirdness is evident without comparison. It is harder to train your mind to have quantum mechanical tuition, because quantum mechanics shatters our own personal, individual conception of reality
It is difficult for me to believe that quantum mechanics, working very well for currently practical set-ups, will nevertheless fail badly with improvements in counter efficiency.
Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle. String theory does so again because a point particle is replaced by a string, which is more spread out.
Quantum mechanics, with its leap into statistics, has been a mere palliative for our ignorance
If you have nothing in quantum mechanics, you will always have something.
Theoretical physicists live in a classical world, looking out into a quantum-mechanical world. The latter we describe only subjectively, in terms of procedures and results in our classical domain.
I think I can safely say that nobody understands Quantum Mechanics.
In relativity, movement is continuous, causally determinate and well defined, while in quantum mechanics it is discontinuous, not causally determinate and not well defined.
Entanglement is not one but rather the characteristic trait of quantum mechanics.
The only object of theoretical physics is to calculate results that can be compared with experiment... it is quite unnecessary that any satisfactory description of the whole course of the phenomena should be given.
