Quotes About Quantum

Maybe time was an illusion after all, as some of the latest scientific theories seemed to suggest.

Sam grudgingly acknowledged the role of consciousness, but argued this, too, was based on unexamined assumptions, dependent on an unfounded faith in the collapse of quantum indeterminacy, and we debated the many minds theory, hidden variables, multiverses, and materialism until the coffee went cold and I'd managed to forget I was anything but pure consciousness myself.

It is important to bear in mind that this is a property of single photons. Each individual photon must be considered to feel out both routes that are open to it, but it remains one photon; it does not split into two photons in the intermediate stage, but its location undergoes the strange kind of complex-number weighted co-existence of alternatives that is characteristic of quantum theory.

string theory is completely different from this. Here there appear to be no results whatever that provide it with experimental

Perhaps it is conceivable that, in the future, some different kind of 'computer' might be introduced, that makes critical use of continuous physical parameters-albeit within the standard theoretical framework of today's physics-enabling it to behave in a way that is essentially different from a digital computer.

Though it indeed seems reasonable to rule out space-time geometries with closed timelike lines as descriptions of the classical universe, a case can be made that they should not be ruled out as potential occurrences that could be involved in a quantum superposition.

Nevertheless, the Geroch-Hartle work does indicate the clear possibility that non-computability may have a genuine role in whatever quantum gravity theory finally emerges as being physically correct.

In the present chapter, we tried to pinpoint the place in the brain where quantum action might be important to classical behaviour, and have apparently been driven to consider that it is through the cytoskeletal control of synaptic connections that this quantum/classical interface exerts its fundamental influence on the brain's behaviour.

At the heart of quantum mechanics is a rule that sometimes governs politicians or CEOs— as long as no one is watching, anything goes.

a negative charge moving backward in time is mathematically equivalent to a positive charge moving forward in time!

But relying on invisible miracles is the stuff of religion, not science. To ascertain whether this remarkable accident was real, physicists relied on another facet of the quantum world. Associated with every background field is a particle, and if you pick a point in space and hit it hard enough, you may whack out real particles.

El universo no es solamente más raro de lo que suponemos, sino más raro de lo que podemos suponer.   J. B. S. HALDANE, 1924

Some theorists have estimated that there are perhaps 10500 different possible consistent four-dimensional universes that could result from a single ten-dimensional string theory.

measurement of a system can alter its behavior

light is an electromagnetic wave.

the remaining 70 percent of the total energy in the universe resided not in any form of matter, but rather in empty space itself.

Whatever is happening on very small scales near the horizon of the black hole will be enlarged by the effect whereby the wavelengths of light are stretched as the light climbs up to us. This means that jf we can observe light coming from very close to the horizon of a black hole, we may be able to see the quantum structure of space itself.

These two discoveries, of relativity and of the quantum, each required us to break definitively with Newtonian physics. However, in spite of great progress over the century, they remain incomplete. Each has defects that point to a deeper theory. But the main reason each is incomplete is the existence of the other.

The main ingredient of the first quantum revolution, wave-particle duality, has led to inventions such as the transistor and the laser that are at the root of the information society.

The role of gender in society is the most complicated thing I've ever spent a lot of time learning about, and I've spent a lot of time learning about quantum mechanics.

I think science and spirituality are one and the same, I don't think they're really different. The film makes pretty clear that quantum physics is validating all kinds of spiritual teachings.

Do you really believe that the moon isn't there when nobody looks?

Spooky action at a distance.
