Niels Bohr Quotes

If you aren't confused by quantum physics, then you haven't really understood it

Anyone not shocked by quantum mechanics has not yet understood it.

Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle.

The more you study quantum mechanics, the more crazy and incomprehensible it becomes. You truly do need a Ph.D. in very high level math and science to understand it at a high, high level.

If someone says that he can think or talk about quantum physics without becoming dizzy, that shows only that he has not understood anything whatever about it.

So the old Copenhagen interpretation needs to be generalized, needs to be replaced by something that can be used for the whole universe, and can be used also in cases where there is plenty of individuality and history.

Quantum theory also tells us that the world is not simply objective; somehow it's something more subtle than that. In some sense it is veiled from us, but it has a structure that we can understand.

The verbal interpretation, on the other hand, i.e. the metaphysics of quantum physics, is on far less solid ground. In fact, in more than forty years physicists have not been able to provide a clear metaphysical model.

A careful analysis of the process of observation in atomic physics has shown that the subatomic particles have no meaning as isolated entities, but can only be understood as interconnections between the preparation of an experiment and the subsequent measurement.

In the future, maybe quantum mechanics will teach us something equally chilling about exactly how we exist from moment to moment of what we like to think of as time.

When one studies the properties of atoms, one found that the reality is far stranger than anybody would have invented in the form of fiction. Particles really do have the possibility of, in some sense, being in more than one place at one time.

Those who are not shocked when they first come across quantum theory cannot possibly have understood it.

I think we can safely assume that no one understands quantum mechanics.

A person who wasn't outraged on first hearing about quantum theory didn't understand what had been said.

No one really understands quantum mechanics.

If we look at the way the universe behaves, quantum mechanics gives us fundamental, unavoidable indeterminacy, so that alternative histories of the universe can be assigned probability.

We talk about quantum weirdness and things being in two places at once, but it all involves atoms and molecules, stuff we don't normally interact with.

The possibilities that are suggested in quantum physics tell us that everything that we're looking at may not be in fact there, so the underlying nature of being is weird.

There are a lot of mysteries about quantum mechanics, but they mostly arise in very detailed measurements in controlled settings.

To me quantum computation is a new and deeper and better way to understand the laws of physics, and hence understanding physical reality as a whole.

Nevertheless, all of us who work in quantum physics believe in the reality of a quantum world, and the reality of quantum entities like protons and electrons.

If I realize that actually there's quantum mechanics happening around us all the time in some macroscopic, interconnected way, then that doesn't change my perception of it, that doesn't change my interaction with it; it just changes how I view my interaction.

The new formula in physics describes humans as paradoxical beings who have two complementary aspects: They can show properties of Newtonian objects and also infinite fields of consciousness.

Quantum physics is one of the hardest things to understand intuitively, because essentially the whole point is that our classical picture is wrong.

It is often stated that of all the theories proposed in this century, the silliest is quantum theory. In fact, some say that the only thing that quantum theory has going for it is that it is unquestionably correct.
