Quantum Quotes
-
If quantum theory is correct, it signifies the end of physics as a science.
-
Ultimately, my Ph.D. is in mathematical physics, focusing on quantum field theory and curved space-time, and I worked with Stephen Hawking.
-
There's been a quantum leap technologically in our age, but unless there's another quantum leap in human relations, unless we learn to live in a new way towards one another, there will be a catastrophe.
-
Among the lesser effects of quantum theory are gaping holes in old ideas about causality.
-
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 more success the quantum theory has, the sillier it looks.
-
Welcome to the strange world of the quantum, where one cannot determine how a particle gets from here to there. Physicists are reduced to bookies, posting odds on the various possibilities.
-
If you think you understand quantum mechanics, you don't understand quantum mechanics.
-
Nature isn't classical, dammit, and if you want to make a simulation of nature, you'd better make it quantum mechanical, and by golly it's a wonderful problem, because it doesn't look so easy.
-
The dividing line between the wave or particle nature of matter and radiation is the moment “Now.” As this moment steadily advances through time it coagulates a wavy future into a particle past.
-
Interference between universes at the quantum level means that information transfer takes place between them.
-
I am fascinated by quantum physics.
-
There's no verbs before time itself exists, right? There's no popping into existence, there's no fluctuating, there's no quantum mechanical craziness, there is literally nothing.
-
It turns out that information leaks between universes at the quantum level. We think it accounts for all kinds of phenomena, from what drives evolution to strange insights and mystical experiences through the ages. The machine was built as an attempt to investigate and amplify them.
-
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.
-
I'm fascinated with quantum physics.
-
After the conversations about Indian philosophy, some of the ideas of Quantum Physics that had seemed so crazy suddenly made much more sense.
-
On quantum theory I use up more brain grease than on relativity.
-
With quantum computers you can calculate how many bits are in the universe, how much energy it takes to flip them, how much energy exists, and use that to rule out lots of things about the universe's history. Anything that takes more bit flips couldn't have happened.
-
As a witness of that period, I am also deeply convinced that John Bell indirectly played a crucial role in the progress of the application of quantum mechanics to individual objects, microscopic and mesoscopic. The example of his intellectual freedom, that had led to the recognition of the importance of entanglement, was no doubt an encouragement to those who were contemplating the possibility of developing new approaches, beyond the so-efficient paradigm developed decades earlier. His example opened the gate for new quantum explorations.
-
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.
-
...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.
-
I think it is not an exaggeration to say that the realization of the importance of entanglement and the clarification of the quantum description of single objects have been at the root of a second quantum revolution, and that John Bell was its prophet. And it may well be that this once purely intellectual pursuit will also lead to a new technological revolution.
-
While classical mechanics correctly predicts the behavior of large objects such as tennis balls, to predict the behavior of small objects such as electrons, we must use quantum mechanics.
