In vita itaque apprime utile est, intellectum seu Rationem, quantum possumus, perficere, et in hoc uno summa hominis felicitas seu beatitudo consistit; quippe beatitudo nihil aliud est, quam ipsa animi acquiescentia quae ex Dei intuitiva cognitione oritur. It is therefore extrememly useful in life to perfect as much as we can the intellect or reason, and of this alone doesthegreatest happiness or blessedness of man exist: for blessedness is nothing else than satisfaction of mind which arises from the intuitive knowledge of God.
If quantum communication and quantum computation are to flourish, a new information theory will have to be developed.hans christian von baeyer
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
O mihi tum longae maneat pars ultima vitae, Spiritus et quantum sat erit tua dicere facta.
Anyone who dares to speak about an aether is regarded as an ignorant and backward mind and he can only lose his credibility in scientific circles, although in reality those who criticize him use the same concept of intermediate medium in other words, whether it be fields, an associated fluid, a probability fluid, a pilot fluid, a quantum fluid, etc.maurice allais
According to Gould and Eldredge, the reason why so many links are missing is that they simply do not exist. They take the view that biological evolution proceeds in successive stages of "punctuated equilibrium." Living species would remain unchanged for extremely long stretches of time, and then undergo profound changes in relatively short periods. To borrow a term from the quantum theory of atoms, evolution would occur in "quantum jumps." It is very likely that the spark of life appeared during the first such "jump."niles eldredge
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
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
Cornelia would not be altogether surprised if she saw the grazing cow start tap dancing, lap dancing, or whatever quantum gravity might cause cows to do.joão magueijo
We are trying to understand the implications of quantum mechanics. The subject is very old, but we are still learning.leonard mandel
As with all quantum devices, a qubit is a delicate flower. If you so much as look at it, you destroy it.hans christian von baeyer
Physics is at present a mass of partial theories which no man has yet been able to render truly and clearly consistent. It has been well said that the modern physicist is a quantum theorist on Monday, Wednesday, and Friday and a student of gravitational relativity theory on Tuesday, Thursday, and Saturday. On Sunday he is praying. . . that someone will find the reconciliation between the two views.Norbert Wiener
“Having presented all the relevant nanoscale mechanisms, thus laying down a firm background for the readers’ understanding, the author moves to the topic of architectural challenges in Chapter 7. This field is claimed still to be an unsolved problem so the author gives examples of currently used technologies and points out potential architectural solutions such as self-assembly, carbon nanotubes, or quantum systems. That is why it makes the book even more valuable for those who intend to involve nanonetworks in their research.”stephen bush
The mathematical framework of quantum theory has passed countless successful tests and is now universally accepted as a consistent and accurate description of all atomic phenomena. The verbal interpretation, on the other hand – i.e., the metaphysics of quantum theory – is on far less solid ground. In fact, in more than forty years physicists have not been able to provide a clear metaphysical model.fritjof capra
Lugete, O Veneres Cupidinesque, Et quantum est hominum venustiorum. Passer mortuus est meae puellae, Passer, deliciae meae puellae.
It seems significant that according to quantum physics the indestructibility of energy on one hand which expresses its timeless existence and the appearance of energy in space and time on the other hand correspond to two contradictory (complementary) aspects of reality. In fact, both are always present, but in individual cases the one or the other may be more pronounced.wolfgang pauli
The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation.
People get a lot of confusion, because they keep trying to think of quantum mechanics as classical mechanics.
I think I can safely say that nobody understands quantum mechanics.
I waive the quantum o' the sin, The hazard of concealing: But, och! it hardens a' within, And petrifies the feeling!Robert Burns
Pro superi! quantum mortalia pectora cæcæ, Noctis habent.
quantum physics is no longer an abstract theory for specialists. We must now absolutely include it in our education and also in our culture.claude cohen-tannoudji
quantum theory was split up into dialects. Different people describe the same experiences in remarkably different languages. This is confusing even to physicists.
quantum theory provides us with a striking illustration of the fact that we can fully understand a connection though we can only speak of it in images and parables.werner heisenberg
The quantum Universe has a quotation from me in every chapter but it's a damn good book anyway.richard feynman
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.
