A Quote by Alain Aspect
The development of quantum mechanics early in the twentieth century obliged physicists to change radically the concepts they used to describe the world.

[Heisenberg's seminal 1925 paper initiating quantum mechanics marked] one of the great jumps—perhaps the greatest—in the development of twentieth century physics.
It has been said that the three great develpments in twentieth century science are relativity, quantum mechanics, and chaos. That strikes me the same as saying that the three great developments in twentith century engineering are the airplane, the computer, and the pop-top aluminum can. Chaos and fractals are not even twentieth century ideas: chaos was first observed by Poincare and fractals were familiar to Cantor a century ago, although neither man had the computer at his disposal to show the rest of the world the beauty he was seeing.
Most 20th century academic physicists, and academia as a whole, simply did not want to touch the subject of consciousness. We have seen psychology grow up, and we've seen the development of neurophysiology and other much more sophisticated science, but only in the recent years have the tools of quantum mechanics been applied to anything representing human scale size.
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
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.
If all people learned to think in the non Aristotelian manner of quantum mechanics, the world would change so radically that most of what we call "stupidity" and even a great deal of what we consider "insanity" might disappear, and the "intractable" problems of war, poverty and injustice would suddenly seem a great deal closer to solution.
Theoretical physicists live in a classical world, looking out into a quantum-mechanical world. The latter we describe only subjectively, in terms of procedures and results in our classical domain.
Quantum mechanics is so counter-intuitive, physicists have never been able to come up with a comfortable picture of how it works.
The birth of science as we know it arguably began with Isaac Newton's formulation of the laws of gravitation and motion. It is no exaggeration to say that physics was reborn in the early 20th-century with the twin revolutions of quantum mechanics and the theory of relativity.
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.
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.
The epithet beautiful is used by surgeons to describe operations which their patients describe as ghastly, by physicists to describe methods of measurement which leave sentimentalists cold, by lawyers to describe cases which ruin all the parties to them, and by lovers to describe the objects of their infatuation, however unattractive they may appear to the unaffected spectators.
Polymeric materials in the form of wood, bone, skin and fibers have been used by man since prehistoric time. Although organic chemistry as a science dates back to the eighteenth century, polymer science on a molecular basis is a development of the twentieth century.
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.
The humanities and science are not in inherent conflict but have become separated in the twentieth century. Now their essential unity must be re-emphasized, so that twentieth-century multiplicity may become twentieth-century unity.
While many questions about quantum mechanics are still not fully resolved, there is no point in introducing needless mystification where in fact no problem exists. Yet a great deal of recent writing about quantum mechanics has done just that.
