According to the standard model billions of years ago some little quantum fluctuation, perhaps a slightly lower density of matter, maybe right where we're sitting right now, caused our galaxy to start collapsing around here.
Seth Lloyd

Because of recent improvements in the accuracy of theoretical predictions based on large scale ab initio quantum mechanical calculations, meaningful comparisons between theoretical and experimental findings have become possible.
Yuan T. Lee

But I don't actually adopt the point of view that our subjective impression of free will, which is a kind of indeterminacy behavior, comes from quantum mechanical indeterminacy.
Murray Gell-Mann

But to do it professionally is a quantum leap difference and my father had to be persuaded by these kind of Ivy League professors that I should go to the Yale Drama School, another one of the stories in there.
Robert Klein

Doing is a quantum leap from imagining.
Barbara Sher

Einstein was searching for String Theory. It not only reconciles General Relativity to Quantum Mechanics, but it reconciles Science and the Bible as well.
Roy H. Williams

I believe that the quantum of our knowledge will increase considerably in the coming years and that scientists will continue to be amongst the brave voices speaking out.
Peter Garrett

I mean, we're really making a quantum change in our relationship to the plant world with genetic modification.
Michael Pollan

I wouldn't have thought that a wrong theory should lead us to understand better the ordinary quantum field theories or to have new insights about the quantum states of black holes.
Edward Witten

If anybody says he can think about quantum physics without getting giddy, that only shows he has not understood the first thing about them.
Niels Bohr

If quantum mechanics hasn't profoundly shocked you, you haven't understood it yet.
Niels Bohr

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.
Murray Gell-Mann

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.
Murray Gell-Mann

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.
James Lovelock

In fact any experiment that measures a quantum effect is one in which the quantum effect is aligned with the behavior of some heavy, macroscopic object; that's how we measure it.
Murray Gell-Mann

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

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.
John S. Bell

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.
John Polkinghorne

Now, what that means is that there is fundamental indeterminacy from quantum mechanics, but besides that there are other sources of effective indeterminacy.
Murray Gell-Mann

Quantum computation is... a distinctively new way of harnessing nature... It will be the first technology that allows useful tasks to be performed in collaboration between parallel universes.
David Deutsch
