Classical Mechanics Quotes

Classical mechanics gave us a deterministic view of the world. Quantum mechanics, conversely, gives us a probabilistic view instead. According to Newton, if you know the cause af an event, you can predict the outcome. According to M.Born, you can only predict how likely that outcome will be. ~ Leonid V. Azaroff

Thus it can be argued that quantum theory provides an opening for an idea of nature and of our role within it that is in general accord with certain religious concepts, but that, by contrast, is quite incompatible with the precepts of mechanistic deterministic classical physics. Thus the replacement of classical mechanics by quantum mechanics opens the door to religious possibilities that formerly were rationally excluded. ~ Paul Davies

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. ~ Ivar Giaever

This question about the reason we do not observe any quantum mechanical uncertainty in the appearance of flies or stars was never tackled by the inventors of quantum mechanics. Given that we are convinced that the basic laws of quantum mechanics are at the bottom of all mechanical laws, and that the beginning of our world can be understood exclusively in quantum mechanical terms, we have to ask ourselves: Why are there any observable systems at all on the classical side of the demarcation line between classical mechanics and quantum mechanics? Why are there these stumbling blocks, these flies, these stars? The demarcation line proper, between quantum physics and classical physics, was clearly stated by the fathers of quantum mechanics: Classical laws govern large and heavy classical systems. But they failed to tell us how and why the world became that way. ~ Henning Genz

People get a lot of confusion, because they keep trying to think of quantum mechanics as classical mechanics ~ Sidney Coleman

Quantum mechanics broke the mold of the previous framework, classical mechanics, by establishing that the predictions of science are necessarily probabilistic. ~ Brian Greene

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

Evolution in quantum mechanics is deterministic as in classical mechanics except for the difference that as the system interacts with another system, its state function collapses. This dichotomy exists only for separated systems, in which one of them is being observed by the other. Given that the state of the entire universe is defined at the initial point, its evolution must be completely deterministic. Any seeming randomness now should merely be an amplification of the randomness in the initial state and the entropy at the origin should not change as the universe evolves. In other words, the physical universe governed by quantum laws has no place for the emergence of life. ~ Subhash Kak

Oh, stuff the critics. I don't care. Too many people are snooty about classical. Look, I wasn't brought up in a home where we listened to classical music. It was a singing teacher that thought it would be best for my voice. Then I moved into crossover. And if that makes the music accessible to more people, then great. ~ Katherine Jenkins

I spent ten years playing classical piano, and that was what led to keyboards and eventually to production and to Linkin Park. ~ Mike Shinoda

Then there are those who think their bodies don't exist. They live by mechanical time. They rise at seven o'clock in the morning. They eat their lunch at noon and their supper at six. They arrive at their appointments on time, precisely by the clock. They make love between eight and ten at night. They work forty hours a week, read the Sunday paper on Sunday, play chess on Tuesday nights. When their stomach growls, they look at their watch to see if it is time to eat. When they begin to lose themselves in a concert, they look at the clock above the stage to see when it will be time to go home. They know that the body is not a thing of wild magic, but a collection of chemicals, tissues, and nerve impulses. Thoughts are no more than electrical surges in the brain. Sexual arousal is no more than a flow of chemicals to certain nerve endings. Sadness no more than a bit of acid transfixed in the cerebellum. In short, the body is a machine, subject to the same laws of electricity and mechanics as an electron or clock. As such, the body must be addressed in the language of physics. And if the body speaks, it is the speaking only of so many levers and forces. The body is a thing to be ordered, not obeyed. ~ Alan Lightman

The road has been viewed as a male turf. If you think of the classic "Odyssey," of, you know, classical literature or Jack Kerouac or almost any road story, it's really about a man on the road. There's an assumption that the road is too dangerous for women. ~ Gloria Steinem

That mainstream English is essential to our self-preservation is indisputable ... but it is not necessary to abandon Spoken Soul to master Standard English, any more than it is necessary to abandon English to learn French or to deprecate jazz to appreciate classical music. ~ John R. Rickford

We Gonna Win' is a song of triumph, It represents my personal belief that with hard work, talent and dedication, everything is possible. It's a one of a kind marriage between rap and classical music, where the music doesn't accompany the vocalist, but rather stands on its own. ~ Miri Ben-Ari

The computational paradigm for the universe supplements the ordinary mechanistic paradigm: the universe is not just a machine, it is a machine that processes information. The universe computes. The computing universe is not a metaphor, but a mathematical fact: the universe is a physical system that can be programmed at its most microscopic level to perform universal digital computation. Moreover, the universe is not just a computer: it is a quantum computer. Quantum mechanics is constantly injecting fresh, random bits into the universe. Because of its computational nature, the universe processes and interprets those bits, naturally giving rise to all sorts of complex order and structure (Lloyd, 2006). ~ Paul Davies

So writing a song is much harder than doing a classical piece for me, because in a classical piece, I can just let the mood dictate what's going to happen. ~ Glenn Danzig

The modern virtues fail because they concern the outer self, the human facade, the part of ourselves the world sees most readily – while the classical virtues form an organizing framework for our inner selves… for our souls. ~ Jonathan V. Last

The Snow White the midnight the moon tales of the mechanics ~ Marissa Meyer

In neo-classical economic theory, it is claimed without evidence that people are basically self-seeking, that they want above all the satisfaction of their material desires: what economists call "maximising utility". The ultimate objective of mankind is economic growth, and that is maximized only through raw, and lightly regulated, competition. If the rewards of this system are spread unevenly, that is a necessary price. Others on the planet are to be regarded as either customers, competitors or factors of production. Effects upon the planet itself are mere "externalities" to the model, with no reckoning of the cost - at least for now. Nowhere in this analysis appears factors such as human cooperation, love, trust, compassion or hatred, curiosity or beauty. Nowhere appears the concept of meaning. What cannot be measured is ignored. But the trouble is that once our basic needs for shelter and food have been met, these factors may be the most important of all. ~ Carne Ross

Every new discovery in science brings with it a host of new problems, just as the invention of the automobile brought with it gas stations, roads, garages, mechanics, and a thousand other subsidiary details. ~ Banesh Hoffmann

I should've probably warned you:
once you end a relationship with an artist,
you are perpetually reminded of them.
They have now ruined classical music and jazz for you.
They have ruined books and poetry.
You should just forget about galleries and museums.
But you know what the worst part is?
It's how they witnessed and observed you,
making you feel like the only person in the room.
And you secretly loved being looked at,
being worshipped.
So now you avoid mirrors.
Because when you look at yourself,
you remember me. ~ Kamand Kojouri

Unlearning the colonialism I was taught, the stories I've been told and I've told myself, is a daily practice, like learning a new language. You learn it by watching films, listening to the radio, reading books. Your ear gets attuned to it. You pick up the vocabulary, learn the system's grammar and mechanics. From there, you can understand and deconstruct it. Sure, learning a language is a solo task, but it helps to have conversation partners. ~ Matt Ortile

On every full moon, rituals ... take place on hilltops, beaches, in open fields and in ordinary houses. Writers, teachers, nurses, computer programmers, artists, lawyers, poets, plumbers, and auto mechanics
women and men from many backgrounds come together to celebrate the mysteries of the Triple Goddess of the Dance of Life. The religion they practice is called Witchcraft. ~ Starhawk

There are a lot of mysteries about quantum mechanics, but they mostly arise in very detailed measurements in controlled settings. ~ Lisa Randall

The best gift I was ever given was the arts. My mum gave me those on a silver platter. Growing up, her and my grandmother would take me to ballets, classical concerts, even smoky jazz clubs I wasn't supposed to be in! ~ Jill Scott

To me, the advantage of the recorder is that it is so natural. I love the fact that it is just a piece of wood, that there are almost no mechanics involved. ~ Michala Petri

Paul Furlong is my vintage Rolls Royce and he cost me nothing. We polish him, look after him, and I have him fine tuned by my mechanics. We take good care of him because we have to drive him every day, not just save him for weddings. ~ Ian Holloway

The fact that we can describe the motions of the world using Newtonian mechanics tell us nothing about the world. The fact that we do, does tell us something about the world. ~ Ludwig Wittgenstein

The great hospitals, houses of confinement, establishments of religion and public order, of assistance and punishment, of governmental charity and welfare measures, are a phenomenon of the classical period: ~ Michel Foucault

Marxist writers are generally either indifferent or mildly hostile to the anti-capitalist movement, which they see as no good substitute for the great projects of communism and social democracy. Now, in one sense this is quite justified[…] However, there seems very little reason to believe that a return to the tactics of the twentieth-century labour movement is going to achieve anything in the future… [W]hat is wrong with commodification is not commodification per se… Marxist tradition goes much further than simply recommending that the excessive power of capital be challenged and curbed. Historically, this tradition tends to assert that such a challenge can only be made by virtue of a direct challenge to the existing relations of production, conceived of as the basis for a social totality, and, crucially, that it can only be made by the proletariat, politically mobilizes as a 'Class of Itself'. In concrete terms, this means that only the labour movement, being organized and mobilized on the basis of its class identity and demanding the socialization of the means of production, can mount such a challenge… This is where I, and the anti-capitalist movement, part company with classical Marxism… [A]nti-capitalist movement is characterized by a certain pluralism, an unwillingness to impose any one model of social organization, and a refusal of neoliberal hegemony not on the basis of a single class identity or even a single universal human identity, but precisely n the basis of a d ~ Jeremy Gilbert

Classical music's ability to translate emotional themes is fantastic. ~ Alan Price

observations suggest that the survivor as ANP typically engages in tasks of daily life such as reproduction, attachment, caretaking, and other social action tendencies, and avoidance of traumatic memories, which support a focus on daily life issues. In contrast, the survivor as EP primarily displays evolutionary defensive and emotional reactions to the (perceived) threat on which he or she seems to be fixated. Third, survivors should be very susceptible to classical conditioning, because, as we discuss below, EP and ANP strongly respond to unconditioned and conditioned threat cues. ~ Onno Van Der Hart

It would take a civilization far more advanced than ours, unbelievably advanced, to begin to manipulate negative energy to create gateways to the past. But if you could obtain large quantities of negative energy - and that's a big "IF" - then you could create a time machine that apparently obeys Einstein's equation and perhaps the laws of quantum theory. ~ Michio Kaku

During this same period of his life Bohm also continued to refine his alternative approach to quantum physics. As he looked more carefully into the meaning of the quantum potential he discovered it had a number of features that implied an even more radical departure from orthodox thinking. One was the importance of wholeness. Classical science had always viewed the state of a system as a whole as merely the result of the interaction of its parts. However, the quantum potential stood this view on its ear and indicated that the behavior of the parts was actually organized by the whole. This not only took Bohr's assertion that subatomic particles are not independent "things, " but are part of an indivisible system one step further, but even suggested that wholeness was in some ways the more primary reality. It also explained how electrons in plasmas (and other specialized states such as superconductivity) could behave like interconnected wholes. As Bohm states, such "electrons are not scattered because, through the action of the quantum potential, the whole system is undergoing a co-ordinated movement more like a ballet dance than like a crowd of unorganized people. " Once again he notes that "such quantum wholeness of activity is closer to the organized unity of functioning of the parts of a living being than it is to the kind of unity that is obtained by putting together the parts of a machine. "6 An even more surprising feature of the quantum potential was its implications fo ~ Michael Talbot

String theory is the most developed theory with the capacity to unite general relativity and quantum mechanics in a consistent manner. I do believe the universe is consistent, and therefore I do believe that general relativity and quantum mechanics should be put together in a manner that makes sense. ~ Brian Greene

What kind of books do you like?'
'I like books about nice people. And a story where it all comes out right in the end.'
'But Nancibel, that's not true to life.'
'I daresay not. Why should it be?'
'You're an escapist.'
'Pardon?'
'You don't want the face facts.'
'Not in story books, I don't. I face plenty between Monday and Saturday without reading about them.'
Bruce sighed.
'I don't think a book ought to be sad,' said Nancibel, 'unless it's a great classical book, like 'Wuthering Heights.'
'Oh! You've read 'Wuthering Heights'. Did you like it?'
'Yes, but I didn't think it was the right part for Merle Oberon. Running about with bare feet, well she was hobbling most of the time. You could see she wasn't used to it.'
'Oh... you mean the film. ~ Margaret Kennedy

I'm a classical type of guy. Whatever's out at that point in time, I like it. I just put my own twist on it, and we go from there. ~ Carmelo Anthony

I've never been really interested in music, classical or otherwise, where the craft is more important than the result. I realized quickly that I'd never be a technical electronic musician. ~ Anna Meredith

There's a cardinal rule in book publishing that applies equally to brain surgery and auto mechanics: "If it ain't broke, don't fix it." Since people are still buying the original Where Is God When It Hurts? ~ Philip Yancey

Quantum attention function is deeply grounded on the mathematics of theoretical physics and penetrates deeply the world of the very small and the world of the very big. ~ Amit Ray

The hell with virtue. I've figured out the mechanics of her dress. ~ Audrey Niffenegger

My earliest memories are of CP4 - that's a Kähler manifold that looks locally like a vector space with four complex directions, though the global topology's quite different. But I didn't really grow up there; I was moved around a lot when I was young, to keep my perceptions flexible. I only used to spend time in anything remotely like this" - he motioned at the surrounding more-or-less-Euclidean space - for certain special kinds of physics problems. And even most Newtonian mechanics is easier to grasp in a symplectic manifold; having a separate visible coordinate for the position and momentum of every degree of freedom makes things much clearer than when you cram everything together in a single three-dimensional space. ~ Greg Egan
