Quantum Quotes
-
One of the main successes of string theory is that it has been able to unify the general theory of relativity, which describes gravity, and quantum mechanics.
-
After the conversations about Indian philosophy, some of the ideas of Quantum Physics that had seemed so crazy suddenly made much more sense.
-
Quantum phenomena do not occur in a Hilbert space. They occur in a laboratory.
-
...contemporary physicists come in two varieties. Type 1 physicists are bothered by EPR and Bell's Theorem. Type 2 (the majority) are not, but one has to distinguish two subvarieties. Type 2a physicists explain why they are not bothered. Their explanations tend either to miss the point entirely (like Born's to Einstein) or to contain physical assertions that can be shown to be false. Type 2b are not bothered and refuse to explain why.

The shell game that we play ... is technically called 'renormalization'. But no matter how clever the word, it is still what I would call a dippy process! Having to resort to such hocus-pocus has prevented us from proving that the theory of quantum electrodynamics is mathematically self-consistent. It's surprising that the theory still hasn't been proved self-consistent one way or the other by now; I suspect that renormalization is not mathematically legitimate.
-
What really matters for me is ... the more active role of the observer in quantum physics ... According to quantum physics the observer has indeed a new relation to the physical events around him in comparison with the classical observer, who is merely a spectator.
-
I liked quantum mechanics very much. The subject was hard to understand but easy to apply to a large number of interesting problems.
-
The history of the universe is, in effect, a huge and ongoing quantum computation. The universe is a quantum computer.
-
In a quantum universe, magic is not the exception but the rule.
-
Build a quantum computer and problems long dismissed as hopeless would melt away. Imagine tapping a fundamental force of nature, not for the purpose of moving around matter but for moving around numbers—explosions of information. Quantum computing would be to ordinary computing what nuclear energy is to fire.
-
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.
-
Classical physics has been superseded by quantum theory: quantum theory is verified by experiments. Experiments must be described in terms of classical physics.
-
Quantum theory was split up into dialects. Different people describe the same experiences in remarkably different languages. This is confusing even to physicists
-
There is a responsibility on all companies to look at the quantum of pay and the relationship between the top and the bottom.
-
The laws of quantum mechanics itself cannot be formulated ... without recourse to the concept of consciousness.
-
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.
-
Quantum mechanics is weird. I don't understand it. Just live with it. You don't have to understand the nature of things in order to build cool devices.
-
Thinking about quantum physics is like unraveling your brain and putting it back together again upside down. Much like studying Kabbalah.
-
What one thing could you do in your personal and professional life that, if you did on a regular basis, would make a tremendous positive difference in your life? Quadrant II activities have that kind of impact. Our effectiveness takes quantum leaps when we do them.
-
In this communication I wish first to show in the simplest case of the hydrogen atom (nonrelativistic and undistorted) that the usual rates for quantization can be replaced by another requirement, in which mention of "whole numbers" no longer occurs. Instead the integers occur in the same natural way as the integers specifying the number of nodes in a vibrating string. The new conception can be generalized, and I believe it touches the deepest meaning of the quantum rules.
