It seems clear that the present quantum mechanics is not in its final form. Some further changes will be needed, just about as drastic as the changes made in passing from Bohr's orbit theory to quantum mechanics. Some day a new quantum mechanics, a relativistic one, will be discovered, in which we will not have these infinities occurring at all. It might very well be that the new quantum mechanics will have determinism in the way that Einstein wanted.

Now he was…dust. To an outside observer, these ten seconds had been ground up into ten thousand uncorrelated moments and scattered throughout real time - and in model time, the outside world had suffered an equivalent fate. Yet the pattern of his awareness remained perfectly intact: somehow he found himself, “assembled himself” from these scrambled fragments. He’d been taken apart like a jigsaw puzzle - but his dissection and shuffling were transparent to him. Somehow - on their own terms - the pieces remained connected. Imagine a universe entirely without structure, without shape, without connections. A cloud of microscopic events, like fragments of space-time … except that there is no space or time. What characterizes one point in space, for one instant? Just the values of the fundamental particle fields, just a handful of numbers. Now, take away all notions of position, arrangement, order, and what’s left? A cloud of random numbers. But if the pattern that is me could pick itself out from all the other events taking place on this planet, why shouldn’t the pattern we think of as ‘the universe’ assemble itself, find itself, in exactly the same way? If I can piece together my own coherent space and time from data scattered so widely that it might as well be part of some giant cloud of random numbers, then what makes you think that you’re not doing the very same thing?

It was about three o’clock at night when the final result of the calculation [which gave birth to quantum mechanics] lay before me. At first, I was deeply shaken. I was so excited that I could not think of sleep. So I left the house and awaited the sunrise on top of a rock. — Werner Heisenberg

Le equazioni della meccanica quantistica e le loro conseguenze vengono usate quotidianamente da fisici, ingegneri, chimici e biologi, nei campi più svariati. Sono utilissime per tutta la tecnologia contemporanea. Non ci sarebbero i transistor senza la meccanica quantistica. Eppure restano misteriose: non descrivono cosa succede a un sistema fisico, ma solo come un sistema fisico viene percepito da un altro sistema fisico. Che significa? Significa che la realtà essenziale di un sistema è indescrivibile? Significa solo che manca un pezzo alla storia? O significa, come a me sembra, che dobbiamo accettare l’idea che la realtà sia solo interazione?

Mankind has uncovered two extremely efficient theories: one that describes our universe's structure (Einstein's gravity: the theory of general relativity), and one that describes everything our universe contains (quantum field theory), and these two theories won't talk to each other.

Margrethe: And when all our eyes are closed, when even the ghosts have gone, what will be left of our beloved world? Our ruined and dishonoured and beloved world?

Many scientists have tried to make determinism and complementarity the basis of conclusions that seem to me weak and dangerous; for instance, they have used Heisenberg's uncertainty principle to bolster up human free will, though his principle, which applies exclusively to the behavior of electrons and is the direct result of microphysical measurement techniques, has nothing to do with human freedom of choice. It is far safer and wiser that the physicist remain on the solid ground of theoretical physics itself and eschew the shifting sands of philosophic extrapolations.

More than ninety-five percent of your brain activity, as you consciously read this sentence, is being used by your subconscious mind.

One hundred thirty-seven is the inverse of something called the fine-structure constant. ...The most remarkable thing about this remarkable number is that it is dimension-free. ...Werner Heisenberg once proclaimed that all the quandaries of quantum mechanics would shrivel up when 137 was finally explained.

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.

Our subconscious thought patterns collapses the quantum wave function and generates the reality. Meditation is streamline the thought patterns.

People are romantic idiots in the ideals of courtship. When a person says they have x, y, and z, their romantic counterpart takes x, y, and z as distinct points in a person's timeline-versus the imperceptibly messy distances in between (and the attributed entanglement). Thus resulting in happily never afters.

Physical reality does not require that we be pleased with its mechanism.

Quantum Machine Learning is defined as the branch of science and technology that is concerned with the application of quantum mechanical phenomena such as superposition, entanglement and tunneling for designing software and hardware to provide machines the ability to learn insights and patterns from data and the environment, and the ability to adapt automatically to changing situations with high precision, accuracy and speed.

Quantum mechanics. What a repository, a dump, of human aspiration it was, the borderland where mathematical rigor defeated common sense, and reason and fantasy irrationally merged. Here the mystically inclined could find whatever they required and claim science as their proof. And for these ingenious men in their spare time, what ghostly and beautiful music it must be--spectral asymmetry, resonances, entanglement, quantum harmonic oscillators--beguiling ancient airs, the harmony of the spheres that might transmute a lead wall into gold and bring into being the engine that ran on virtually nothing, on virtual particles, that emitted no harm and would power the human enterprise as well as save it. Beard was stirred by the yearnings of these lonely men. And why should he think they were lonely? It was not, or not only, condescension that made him think them so. They did not know enough, but they knew too much to have anyone to talk to. What mate waiting down the pub or in the British Legion, what hard-pressed wife with job and kids and housework, was going to follow them down these warped funnels in the space-time continuum, into the wormhole, the shortcut to a single, final answer to the global problem of energy?

Some people, including Hawking, think that we may be able to understand the big bang or the big crunch (in particular, whether time has a beginning or an end at these events) when we have a satisfactory quantum theory of gravitation.

So much love, so much time.

The answer to the ancient question 'Why is there something rather than nothing?' would then be that ‘nothing’ is unstable.

The belief in causality is metaphysical. It is nothing but a typical metaphysical hypostatization of a well-justified methodological rule- the scientist's decision never to abandon his search for laws. The metaphysical belief in causality seems thus more fertile in its various manifestations than any indeterminist physics metaphysics of the kind advocated by Heisenberg. Indeed, we can see that Heisenberg's comments have had a crippling effect on research. Connections which are not far to seek may easily be overlooked if its continually repeated that the search for any such connections is 'meaningless'.

The mind reels when we realize that, according to this interpretation of quantum mechanics, all possible worlds coexist with us. Although wormholes might be necessary to reach such alternate worlds, these quantum realities exist in the very same room that we live in. They coexist with us wherever we go.

The more we delve into quantum mechanics the stranger the world becomes; appreciating this strangeness of the world, whilst still operating in that which you now consider reality, will be the foundation for shifting the current trajectory of your life from ordinary to extraordinary.

The particles that are the very building blocks of all things, are in all possible locations until observation/measurement causes them to choose a specific position.

The Quantum Mechanic will fix your car, but it won’t work unless you observe him fixing it

The [quantum] theory reminds me a little of the system of delusions of an exceedingly intelligent paranoiac.

There are just some things that are outside of comprehension, even if we can quantify them. At some point, science becomes magic.

There are many, many, many worlds branching out at each moment you become aware of your environment and then make a choice.

There has been much controversy about what is meant by an observation causing a quantum entity to come into existence. The controversy is caused by ambiguity in the meaning of terms such as existence and reality. No one seems to know what they mean in the context of quantum mechanics, so I will explain what they mean. The correct interpretation is that when we say that quantum entities do not exist except when observed, we mean they do not exist as part of the human sensory world created by the human sensory apparatus, when an observation is made. The human sensory world is the world we know and live in, and is the world given to us by our sensory apparatus. There is nothing to stop quantum entities existing in other worlds when being observed in the human sensory world and when not being observed in the human sensory world. In addition all observations made by a human observer are personal to that observer, although other human observers will perceive something very similar to that which is observed by other human observers due to having very similar sensory apparatus. The evidence we perceive in our experiments which indicates the presence of quantum entities should be treated in the same way as our perceptions of tables, trees and people in the macro world. ... We don't actually see quantum entities, we see macro level evidence the quantum entities exist, and this macro level evidence comes into existence in exactly the same way as everything else in the macro world. The solution to the quantum measurement problem lies not in the quantum world, but in how the human sensory apparatus works in the macro world.

There’s a cellular automaton called TVC. After Turing, von Neumann and Chiang. Chiang’s version was N-dimensional. That leaves plenty of room for data within easy reach. In two dimensions, the original von Neumann machine had to reach further and further - and wait longer and longer - for each successive bit of data. In a six-dimensional TVC automaton, you can have a three-dimensional grid of computers, which keeps on growing indefinitely - each with its own three-dimensional memory, which can also grow without bound. And when the simulated TVC universe being run on the physical computer is suddenly shut down, the best explanation for what I’ve witnessed will be a continuation of that universe - an extension made out of dust. Maria could almost see it: a vast lattice of computers, a seed of order in a sea of random noise, extending itself from moment to moment by sheer force of internal logic, “accreting” the necessary building blocks from the chaos of non-space-time by the very act of defining space and time.

There was a young lady named Bright, Whose speed was far faster than light; She started one day In a relative way, And returned on the previous night.

The strength of the familiar electromagnetic force between two electrons, for example, is expressed in physics in terms of a constant known as the fine structure constant. The value of this constant, almost exactly 1/137, has puzzled many generations of physicists. A joke made about the famous English physicist Paul Dirac (1902-1984), one of the founders of quantum mechanics, says that upon arrival to heaven he was allowed to ask God one question. His question was: "Why 1/137?

The very small quantum world, it seems, is a mixture of possibilities. The quantum fields to which all particles belong are the sum of these possibilities and, somehow, one possibility is chosen out of all the existing ones just by seeing it, just by the very act of detecting it, whenever one tries to probe a particle's nature. Nobody knows why or how this happens.

Miller believes, like many theists, that religion brings us beyond the bounds of materialism. (Ironically he insists on a material explanation [evolution] for our existence.) However, he fails to explain how religion does this. Will religion enable us to overcome Heisenberg's Uncertainty Principle? Will the secrets of Miller's black box of quantum mechanics be revealed? Will chance and chaos be things of the past? If religion can't help us solve these mysteries, take us beyond the bounds of our material understanding, then Miller's belief is just so much wishful thinking. However, during one of his more coherent, non-blonde moments, Miller makes one of his strongest points: Science only concerns itself with the material universe, so we must look beyond science if we are to have morals. I can't say I disagree. However, morals don't have to come from an imaginary sky daddy. They could be rationally conceived and practiced to create an orderly society. And, why should science limit itself to the material universe? Morals can be tried and tested; bad morals can be weeded out while good morals are preserved. Such has already happened. Consider the fact that most parents no longer obey God's command to kill their children when they misbehave. Yet, those same parents abstain from stealing and adultery.

Quantum fluctuations are, at their root, completely a-causal, in the sense that cause and effect and ordering of events in time is not a part of how these fluctuations work. Because of this, there seem not to be any correlations built into these kinds of fluctuations because 'law' as we understand the term requires some kind of cause-and-effect structure to pre-exist. Quantum fluctuations can precede physical law, but it seems that the converse is not true. So in the big bang, the establishment of 'law' came after the event itself, but of course even the concept of time and causality may not have been quite the same back then as they are now.

Quantum Mechanics can indeed be extremely complex to grasp, but when we talk about Consciousness, with decades of rigorous studies on the human brain we have realized that actually, there is no other phenomenon in the entire universe that is simpler than the majestic phenomenon of Consciousness. 'If you think you have a solution to the problem of consciousness, you haven’t understood the problem.' This age-old metaphysical and philosophical argument is strictly not true. If you are sufficiently clear-sighted enough, you can realize the problem itself was a matter of the past when we didn’t have insight into the neurological basis of consciousness. And today it is common knowledge in Neuroscience that, all mesmerizing features of the Human Mind, including the glorious Human Consciousness, are born from the tiny specks of jelly inside your head.

Quantum physics tells us that no matter how thorough our observation of the present, the (unobserved) past, like the future, is indefinite and exists only as a spectrum of possibilities. The universe, according to quantum physics, has no single past, or history. The fact that the past takes no definite form means that observations you make on a system in the present affect its past.

Seriousness of mind was a prerequisite for understanding Newtonian physics. I am not convinced it is not a handicap in understanding quantum theory.

She figured that the main problem in physics is physicists, that most of them are caught in a mind trap because they're so used to things being made of smaller things. So they instinctively believe that reality, at its most basic level, must be made up of and regulated by almost infinitely small elementary particles.

The Copenhagen Interpretation has long been the orthodox view of the quantum world and this is not surprising considering how weird the alternatives are. However realism has usually been assumed in the macro world, but given the modern research into animal senses, neurology, and cognitive psychology, realism must inevitably cease to be a serious explanation of the macro world. It seems quite obvious the macro world is sense dependent and the orthodox interpretation of the quantum world postulates a sense dependent world as well. This suggests the same rules can apply to both the macro and quantum worlds which eliminates the need for a dividing line between the two worlds.

The nature of the 'collapse of the wave function' is determined by our self-concept stored in the subconscious mind. Our subconscious mind is aware of the 'many-worlds' occurring simultaneously and chooses the reality we continue to exist in based on our self-concept.

The subconscious mind is the guiding force for your entire life.

The subconscious mind is aware of the many worlds unfolding in each moment.

The subconscious mind is shielding or showing numerous potential paths, based on what it determines would represent a consistent reality for you.

To access your subconscious, is to access your 'higher-self.

To shift your life in a desired direction, you must powerfully shift your subconscious.

To strengthen the connection between your conscious and subconscious, is to gain access to a map and compass, as you travel through parallel worlds.

To study the self is to forget the self. Maybe if you sat enough zazen, your sense of being a solid, singular self would dissolve and you could forget about it. What a relief. You could just hang out happily as part of an open-ended quantum array.

Universe is like a soup of consciousness. Brain is just a receiver. Awareness is continuously transforming thoughts into matter.

We are a manifestation that we perpetuate through space-time. Death is the ceasing of the observation of it whether by direct or indirect influence.

We are Love experiencing itself, in myriad ways.

We are not talking about waves or particles, what we are talking about is a quantum of action in a field. This thing we call a particle is a quantum of action that becomes more focused by a process we have not described and this thing we call a wave is the potential in the field. How can a wave be quantized? The wave is a precise ratio of potential.
