Quotes About Quantum

Physics out of quantum equilibrium contains several surprises. One is that it becomes possible to send information faster than light. This is a consequence of another result of Valentini's, which tells us that while the system is out of quantum equilibrium, information and energy can be sent instantaneously, contradicting special relativity.

Quantum theory can be described as a new kind of language to be used in a dialogue between us and the systems we study with our instruments. This quantum language contains verbs that refer to our preparations and measurements and nouns that refer to what is then seen. It tells us nothing about what the world would be like in our absence.

It is interesting to note that the quantum-mechanical revolution was made by a virtually orphaned generation of scientists. Many members of the generation above them had been slaughtered in World War I. There simply weren't many senior scientists around to tell them they were crazy.

Basically, string theory is the development of this visionary idea in a context of a fixed background of space and time. Loop quantum gravity is the same idea but developed in a completely background-independent theory.

In practice, the greatest amount of information that may be stored behind a horizon is huge - 10^66 bits of information per square centimetre.

So the challenge for any quantum theory of gravity is to give us a deeper understanding of Bekenstein's entropy and Hawking's temperature.

So we may now pose a question which could be answered only if we have a quantum theory of gravity. What is the nature of the information trapped in a quantum black hole? Keep this in mind as we go ahead and explore the different approaches to quantum gravity, for a good test of a theory of quantum gravity is how well it is able to answer this question.

Quantum mechanics has to be expanded, to allow for many different descriptions, depending on who the observer is.

To my great surprise — and slight annoyance — I found that Seth eloquently and lucidly articulated a view of reality that I had arrived at only after great effort and an extensive study of both paranormal phenomena and quantum physics. …" — Michael Talbot, author of The Holographic Universe

Statistical physics or Newtonian physics gives way to quantum physics. Very unusual properties of matter emerge at that scale, and you can think about building products in a very different way. You can think about interfacing to biology in a very different way.

Readers probably haven't heard much about it yet, but they will. Quantum technology turns ordinary reality upside down.

Thinking about quantum physics is like unraveling your brain and putting it back together again upside down. Much like studying Kabbalah.

Nevertheless, all of us who work in quantum physics believe in the reality of a quantum world, and the reality of quantum entities like protons and electrons.

And a new philosophy emerged called quantum physics, which suggest that the individual's function is to inform and be informed. You really exist only when you're in a field sharing and exchanging information. You create the realities you inhabit.

But here's what physicists tell us. Things, in the quantum world, do not happen in steps. They happen immediately.

our thoughts actually interacted with the physical world, whether or not we knew it, effecting change all the way down to the subatomic realm.

The journey's end is to understand what it means—and how—to bring intelligence to emotion. This understanding itself can help to some degree; bringing cognizance to the realm of feeling has an effect something like the impact of an observer at the quantum level in physics, altering what is being observed.

Newtonian physics runs into problems at the subatomic level. Down there--in the land of hadrons, quarks, and Schrödinger's cat--things gent freaky. The cool rationality of Isaac Newton gives way to the bizarre unpredictability of Lewis Carroll.

Not only is the Universe stranger than we think, it is stranger than we can think.

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.

I think that modern physics has definitely decided in favor of Plato . In fact the smallest units of matter are not physical objects in the ordinary sense; they are forms, ideas which can be expressed unambiguously only in mathematical language.

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.

Here the attention of the research workers is primarily directed to the problem of reconciling the claims of the special relativity theory with those of the quantum theory. The extraordinary advances made in this field by Dirac ... leave open the question whether it will be possible to satisfy the claims of the two theories without at the same time determining the Sommerfeld fine-structure constant.

We can never know anything.
