Quotes about quantum-mechanics

You are deluded if you think that the world around you is a physical construct separate from your own mind.

When you look at the external reality, you may assume you know everything, but when you close your eyes and try to look into the darkness of your internal reality, all the knowledge of the external life fails to create a way out of the darkness.

The very nature of the quantum theory ... forces us to regard the space-time coordination and the claim of causality, the union of which characterizes the classical theories, as complementary but exclusive features of the description, symbolizing the idealization of observation and description, respectively.

In the world of the very small, where particle and wave aspects of reality are equally significant, things do not behave in any way that we can understand from our experience of the everyday world...all pictures are false, and there is no physical analogy we can make to understand what goes on inside atoms. Atoms behave like atoms, nothing else.

...quantum mechanics—the physics of our world—requires that you hold such pedestrian complaints in abeyance.

Where misunderstanding dwells, misuse will not be far behind. No theory in the history of science has been more misused and abused by cranks and charlatans—and misunderstood by people struggling in good faith with difficult ideas—than quantum mechanics.

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.

If the business of physics is ever finished, the world will be a much less interesting place in which to live . . .

Einstein said that if quantum mechanics were correct then the world would be crazy. Einstein was right - the world is crazy.

Which came first — the observer or the particle?

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.

The Theory of Relativity confers an absolute meaning on a magnitude which in classical theory has only a relative significance: the velocity of light. The velocity of light is to the Theory of Relativity as the elementary quantum of action is to the Quantum Theory: it is its absolute core.

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.

The ultimate aim of reality is to become science fiction!

Based upon quantum mechanics, our physical reality should not be solid. Most likely our physical reality is an elaborate illusion within our own consciousness and the collective consciousness of the Universe/God.

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

If we look upon the earth as a place where our 'higher selves' have come to learn, to experience, or even to be judged, then the splitting of realities that occurs with the many-worlds interpretation is merely an extension of these functions.

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

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.

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.

Heisenberg's uncertainty relation measures the amount by which the complementary descriptions of the electron, or other fundamental entities, overlap. Position is very much a particle property - particles can be located precisely. Waves, on the other hand, have no precise location, but they do have momentum. The more you know about the wave aspect of reality, the less you know about the particle, and vice versa. Experiments designed to detect particles always detect particles; experiments design

Calculate the fine structure constant from first principles.

A university student attending lectures on general relativity i the morning and others on quantum mechanics in the afternoon might be forgiven for thinking that his professors are fools, or have neglected to communicate with each other for at least a century.

[..] when we get down to the subatomic level, the solid world we live in also consists, again rather worryingly, of almost nothing and that wherever we do find something it turns out not to actually something, but only the probability that there may something there.

Electrons, when they were first discovered, behaved exactly like particles or bullets, very simply. Further research showed, from electron diffraction experiments for example, that they behaved like waves. As time went on there was a growing confusion about how these things really behaved ---- waves or particles, particles or waves? Everything looked like both.This growing confusion was resolved in 1925 or 1926 with the advent of the correct equations for quantum mechanics. Now we know how the e

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.

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

Another very good test some readers may want to look up, which we do not have space to describe here, is the Casimir effect, where forces between metal plates in empty space are modified by the presence of virtual particles.Thus virtual particles are indeed real and have observable effects that physicists have devised ways of measuring. Their properties and consequences are well established and well understood consequences of quantum mechanics.

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

You are the individual and the entire Universe.

All perception is the result of electrical impulses in the brain - the world of the individual is tantamount to a highly advanced computer running and analyzing programs in its working memory.

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.

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.

A mathematician is an individual who proves his beliefs with equations.

It is the definition of the word 'object' which destroys all religions.

[T]he atoms or elementary particles themselves are not real they form a world of potentialities or possibilities rather than one of things or facts.

What believer of faith among us can claim to understand the exact mechanistic structure of a world created by a god/God.

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?

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

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

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.

Is the purpose of theoretical physics to be no more than a cataloging of all the things that can happen when particles interact with each other and separate? Or is it to be an understanding at a deeper level in which there are things that are not directly observable (as the underlying quantized fields are) but in terms of which we shall have a more fundamental understanding?
