Werner Heisenberg Quotes

The more precise the measurement of position, the more imprecise the measurement of momentum, and vice versa.

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

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.

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.

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

In relativity, movement is continuous, causally determinate and well defined, while in quantum mechanics it is discontinuous, not causally determinate and not well defined.

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.

There certainly is a tension between the relativity of simultaneity and non-locality in quantum theory, but it's not strong enough to add up to a falsification of either side by itself.

Old Newtonian physics claimed that things have an objective reality separate from our perception of them. Quantum physics, and particularly Heisenberg's Uncertainty Principle, reveal that, as our perception of an object changes, the object itself literally changes.

There is nothing new to be discovered in physics now, All that remains is more and more precise measurement

Quantum physics is quite interesting. All these tiny particles are there as much as they're not there. That to me is very, very interesting. And how our thoughts change the outcome of an experiment, I think that's all quite spiritual.

It is true that in quantum theory we cannot rely on strict causality. But by repeating the experiments many times, we can finally derive from the observations statistical distributions, and by repeating such series of experiments, we can arrive at objective statements concerning these distributions.

We appear to have form, but we are like a whirlpool. We appear to have form, but we are just whirling electrons.

When we try to observe things that are very small, the act of observation itself will significantly disturb the state we are seeking to measure.

Earlier in this century, the Heisenberg Principle established that the very act of observing a natural phenomenon can change what is being observed. Although the initial theory was limited in practice to special cases in subatomic physics, the philosophical implications were and are staggering.

The 'path' comes into existence only when we observe it.

Life is strong and fragile. It's a paradox... It's both things, like quantum physics: It's a particle and a wave at the same time. It all exists all together.

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.

The main ingredient of the first quantum revolution, wave-particle duality, has led to inventions such as the transistor and the laser that are at the root of the information society.

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.

I'm fascinated with quantum physics.

Spooky action at a distance.

In subjects that physicists think of as purely quantum, classical ideas and classical computational techniques can often be powerful.
