All this, the positive and physical essence of mechanics, which makes its chief and highest interest for a student of nature, is in existing treatises completely buried and concealed beneath a mass of technical considerations.
It seems to me that we must make a distinction between what is "objective" and what is "measurable" in discussing the question of physical reality, according to quantum mechanics. The state-vector of a system is, indeed, not measurable , in the sense that one cannot ascertain, by experiments performed on the system, precisely (up to proportionality) what the state is; but the state-vector does seem to be (again up to proportionality) a completely objective property of the system, being completely characterized by the results it must give to experiments that one might perform.roger penrose
Ananke must above all be regarded as cosmic force , that is as the ruling law in the universe ; thus … the super-personal, cosmic significance of "the All" ruled by Ananke as well, can be accepted as certain. It represents in the universe the inviolability of cause and effect and does so as dual essence, as a mythical personage belonging to the oldest theogony or as the earliest philosophical concept of the mechanics of natural events.
As in earlier days were our mechanics, such todayare our engineers, who may be required not only to tear down a fortress, and then to build it up again, but also to produce all sorts of engines based on mechanical principles, and with equal easeto defend or toannihilate a fortress.Jakob Leupold
You are menaced by the goodness of your mechanics.
Geometry is that part of universal mechanics which accurately proposes and demonstrates the art of measuring.
It must be confessed that the new quantum mechanics is far from satisfying the requirements of the layman who seeks to clothe his conceptions in figurative language. Indeed, its originators probably hold that such symbolic representation is inherently impossible. It is earnestly to be hoped that this is not their last word on the subject, and that they may yet be successful in expressing the quantum postulate in picturesque form.H. Stanley Allen
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
The laws of classical mechanics represent a mathematical idealization and should not be assumed to correspond to the real laws of nature. ... We now have to realize that errors are inevitable (..) a discovery that makes strict determinism impossible.léon brillouin
I am coming more and more to the conviction that the necessity of our geometry cannot be demonstrated, at least neither by, nor for, the human intellect. . . Geometry should be ranked, not with arithmetic, which is purely aprioristic, but with mechanics.carl friedrich gauss
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.murray gell-mann
Quantum mechanics as it stands would be perfect if we didn't have the quantum-gravity issue and a few other very deep fundamental problems.gerardus 't hooft
One element that seems to run throughout Martin's forty years of work is the physical and psychological mechanics of the body/mind. Whether spirited in animals or manifested through abstraction, they are about ourselves: our neurosis, the dreams we hope for, how we eat... Ultimately though, they reveal our resistance to escape the gravitational pull of stillness - the inevitable conclusion to life.eugene j. martin
... one can still say that quantum mechanics is the key to understanding magnetism. When one enters the first room with this key there are unexpected rooms beyond, but it is always the master key that unlocks each door.
In the beginning was mechanics.
Is it not good to know what follows from what, even if it is not necessarily FAPP? [FAPP is Bell's suggested abbreviation of "for all practical purposes."] Suppose for example that quantum mechanics were found to resist precise formulation. Suppose that when formulation beyond FAPP was attempted, we find an unmovable finger obstinately pointing outside the subject, to the mind of the observor, to the Hindu scriptures, to God, or even only Gravitation? Would that not be very, very interesting?john stewart bell
To my mind this makes psychedelics central to any political reconstruction, because these are the only force in nature that actually dissolve linguistics structures; lets the mechanics of syntax to be visible, allows the possibility for rapid introduction and spread of new concepts; gives permission for new ways of seeing; and this is what we have to do, we have to change our minds.terence mckenna
Quantum mechanics is certainly imposing. But an inner voice tells me that it is not yet the real thing. The theory says a lot, but does not really bring us any closer to the secret of the "old one." I, at any rate, am convinced that He does not throw dice.
To the art of mechanics is owing all sorts of instruments to work with, all engines of war, ships, bridges, mills, curious roofs and arches, stately theatres, columns, pendent galleries, and all other grand works in building. Also clocks, watches, jacks, chariots, carts and carriages, and even the wheel-barrow. Architecture, navigation, husbandry , and military affairs, owe their invention and use to this art.
Experimental physics was particularly interested in the processes taking place inside the atom, and in this field the classical mechanics was failing conspicuously and completely. Perhaps its most spectacular failure was with the fundamental problem with the structure of the atom.
Herschel has noticed how the Stagirite obstructed the progress of astronomy by not identifying celestial with terrestrial mechanics, but laying down the principle that celestial motions were regulated by peculiar laws, thus placing them entirely without the pale of experimental research, while at the same time the progress of mechanics was impeded by the [his] assumption of natural and unnatural motions.
In the beginning was mechanics.
There is no machine or mechanism [as compared with the steam engine] in which the little the theorists have done is more useless. It arose, was improved and perfected by working mechanics and by them only.
In the the past thirty years, what is now known as the science of industrial management has grown from a scattered, almost formless beginning into a well-defined, rapidly developing structure. Today this science bids fair to outstrip in public importance and economic usefulness any one of the great sciences that have been applied to serve mankind. For the science of industrial management is the great super-science that takes mechanics, chemistry, physics, electricity, psychology; and Burbank-like, grafts them all into one great, productive, ever-bearing plant.
No physical theory of local hidden variables can ever reproduce all of the predictions of quantum mechanics.
