A Quote by Ivar Giaever
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.

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.
People get a lot of confusion, because they keep trying to think of quantum mechanics as classical mechanics.
Quantum mechanics broke the mold of the previous framework, classical mechanics, by establishing that the predictions of science are necessarily probabilistic.
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.
'Participant' is the incontrovertible new concept given by quantum mechanics. It strikes down the 'observer' of classical theory, the man who stands safely behind the thick glass wall and watches what goes on without taking part. It can't be done, quantum mechanics says it...May the universe in some sense be 'brought into being' by the participation of those who participate?
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
Pinball games were constrained by physical limitations, ultimately by the physical laws that govern the motion of a small metal ball. The video world knows no such bounds. Objects fly, spin, accelerate, change shape and color, disappear and reappear. Their behavior, like the behavior of anything created by a computer program, is limited only by the programmer's imagination. The objects in a video game are representations of objects. And a representation of a ball, unlike a real one, never need obey the laws of gravity unless its programmer wants it to.
The doctrine that the world is made up of objects whose existence is independent of human consciousness turns out to be in conflict with quantum mechanics and with facts established by experiment.
Objects obey quantum laws- they spread in possibility following the equation discovered by Erwin Schodinger- but the equation is not codified within the objects. Likewise, appropriate non-linear equations govern the dynamical response of bodies that have gone through the conditioning of quantum memory, although this memory is not recorded in them. Whereas classical memory is recorded in objects like a tape, quantum memory is truly the analog of what the ancients call Akashic memory, memory written in Akasha, Emptiness- nowhere.
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.
Just because quantum mechanics is weird does not mean that everything that is weird is quantum mechanics.
When the province of physical theory was extended to encompass microscopic phenomena through the creation of quantum mechanics, the concept of consciousness came to the fore again. It was not possible to formulate the laws of quantum mechanics in a fully consistent way without reference to the consciousness.
Quantum mechanics is just completely strange and counterintuitive. We can't believe that things can be here [in one place] and there [in another place] at the same time. And yet that's a fundamental piece of quantum mechanics. So then the question is, life is dealing us weird lemons, can we make some weird lemonade from this?
As an adult I discovered that I was a pretty good autodidact, and can teach myself all kind of things. And developed a great interest in a number of different things from how to build a street hot rod from the ground up to quantum mechanics, and those two different kinds of mechanics, and it was really in the sciences, quantum mechanics, molecular biology, I would begin looking at these things looking for ideas, but in fact you don't read it for ideas you read it for curiosity and interest in the subject.
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.
