A Quote by David Gross

Since the founding of quantum mechanics in the 1920s, theoretical physics had nurtured an extremely radical tradition.

Certainly we do not need quantum mechanics for macroscopic objects, which are well described by classical physics - this is the reason why quantum mechanics seems so foreign to our everyday existence.

Alain Aspect

In quantum mechanics there is A causing B. The equations do not stand outside that usual paradigm of physics. The real issue is that the kinds of things you predict in quantum mechanics are different from the kinds of things you predict using general relativity. Quantum mechanics, that big, new, spectacular remarkable idea is that you only predict probabilities, the likelihood of one outcome or another. That's the new idea.

Brian Greene

The quantum entered physics with a jolt. It didn't fit anywhere; it made no sense; it contradicted everything we thought we knew about nature. Yet the data seemed to demand it. ... The story of Werner Heisenberg and his science is the story of the desperate failures and ultimate triumphs of the small band of brilliant physicists who-during an incredibly intense period of struggle with the data, the theories, and each other during the 1920s-brought about a revolutionary new understanding of the atomic world known as quantum mechanics.

David C. Cassidy

A gifted experimentalist, and theoretician, in the best Newtonian tradition... His contributions to quantum measurements, and elucidative teachings on quantum mechanics, have not yet received the attention they deserve.

Willis Lamb

Quantum Mechanics is different. Its weirdness is evident without comparison. It is harder to train your mind to have quantum mechanical tuition, because quantum mechanics shatters our own personal, individual conception of reality

Brian Greene

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

Edward Witten

Nature is one. It is not divided into physics, chemistry, quantum mechanics.

Albert Szent-Gyorgyi

Quantum mechanics has explained all of chemistry and most of physics.

Paul Dirac

It seems sensible to discard all hope of observing hitherto unobservable quantities, such as the position and period of the electron... Instead it seems more reasonable to try to establish a theoretical quantum mechanics, analogous to classical mechanics, but in which only relations between observable quantities occur.

Werner Heisenberg

Ancient wisdom and quantum physicists make unlikely bedfellows: In quantum mechanics the observer determines (or even brings into being) what is observed, and so, too, for the Tiwis, who dissolve the distinction between themselves and the cosmos. In quantum physics, subatomic particles influence each other from a distance, and this tallies with the aboriginal view, in which people, animals, rocks, and trees all weave together in the same interwoven fabric.

Huston Smith

One of the most exciting things about dark energy is that it seems to live at the very nexus of two of our most successful theories of physics: quantum mechanics, which explains the physics of the small, and Einstein's Theory of General Relativity, which explains the physics of the large, including gravity.

Adam Riess

...quantum mechanics—the physics of our world—requires that you hold such pedestrian complaints in abeyance.

Brian Greene

Before the discovery of quantum mechanics, the framework of physics was this: If you tell me how things are now, I can then use the laws of physics to calculate, and hence predict, how things will be later.

Brian Greene

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.

Edward Witten

I never studied science or physics at school, and yet when I read complex books on quantum physics I understood them perfectly because I wanted to understand them. The study of quantum physics helped me to have a deeper understanding of the Secret, on an energetic level.
