Quotes About Quantum

A single photon seems to "know" if there are two slits open or only one slit open and it behaves differently accordingly!

The speed of light is about 300,000 kilometers per second.

Between successive measurements along the z axis, we turn through 90 degrees, make an intermediate measurement, and turn it back to its original direction. Will a subsequent measurement along the z axis confirm the original measurement? The answer is no. The

Quantum mechanics can be appreciated, to some degree, on a purely qualitative level. But mathematics is what brings its beauty into sharp focus. We have tried to make this amazing body of work fully accessible to mathematically literate nonphysicists.

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.

The development of quantum mechanics early in the twentieth century obliged physicists to change radically the concepts they used to describe the world.

Well, I've always thought that my career was in England, really. I used to do more in the theatre, and I felt that I should be there. It's not far is it? It's amazing the way that special FX have taken a quantum leap in what they're capable of doing.

When you think about the complexity of our natural world - plants using quantum mechanics for photosynthesis, for example - a smartphone begins to look like a pretty dumb object.

You said, 'Why do I frighten you?' Frighten me? Yes you do frighten me. You act as though we will be together for ever. You act as though there is infinite pleasure and time without end. How can I know that? My experience has been that time always ends. In theory you are right, the quantum physicists are right, the romantics and the religious are right.

My experience has been that times always ends. In theory, you are right, the quantum physicists are right, the religious and romantics are right. Time without end. In practice we both wear a watch.

This is a quantum universe,' said Spike, 'neither random nor determined. It is potential at every second. All you can do is intervene.

My grandmother whispering to herself, over and over, David is in heaven now, David is in heaven now,' my mind repeating Schrodinger's Cat, Schrodinger's Cat.

A book on the new physics, if not purely descriptive of experimental work, must essentially be mathematical.

You have that one basic string, but it can vibrate in many ways. But we're trying to get a lot of particles because experimental physicists have discovered a lot of particles.

Spreading out the particle into a string is a step in the direction of making everything we're familiar with fuzzy. You enter a completely new world where things aren't at all what you're used to.

Bohr's influence on the physics and the physicists of our century was stronger than that of anyone else, even than that of Albert Einstein.

Indeed, our everyday world presents intellectual challenges just as daunting as those of the cosmos and the quantum, and that is where 99 per cent of scientists focus their efforts. Even the smallest insect, with its intricate structure, is far more complex than either an atom or a star.

The Machine will reinvent the fundamental architecture of computers to enable a quantum leap in performance and efficiency, while lowering costs over the long term and improving security.

The tug of the lodestar slowly grew stronger until, with an abrupt quantum jump, it was a physical force prying at her mind. She felt everything else fall away, felt the same out-of-body swoon she'd experienced on First Foot when she'd stared too long at the star at the edge of the Badlands. Felt as if she was expanding beyond her body the room the ship into everywhere …

No scientific theory touches on the mysteries that the religious tradition addresses. A man asking why his days are short and full of suffering is not disposed to turn to algebraic quantum field theory for the answer. The answers that prominent scientific figures have offered are remarkable in their shallowness.

The essential feature in quantum interconnectedness is that the whole universe is enfolded in everything, and that each thing is enfolded in the whole.

relativity and quantum theory agree, in that they both imply the need to look on the world as an undivided whole, in which all parts of the universe, including the observer and his instruments, merge and unite in one totality. In this totality, the atomistic form of insight is a simplification and an abstraction, valid only in some limited context.

We propose instead that the basic element be a moment which, like the moment of consciousness, cannot be precisely related to measurements of space and time, but rather covers a somewhat vaguely defined region which is extended in space and has duration in time.

If one computes the amount of energy that would be in one cubic centimeter of space, with this shortest possible wavelength, it turns out to be very far beyond the total energy of all the matter known in the universe.
