Quotes About Quantum

Like human lovers, electrons are unpredictable, fickle, and always open to better offers.

Quantum physics shows that it is in the nature of reality to be unpredictable.

The whole quantum setup ends up being embarrassing in the special way something pretentious is embarrassing when it's also wrong.

1962 that "No data processing system, whether artificial or living, can process more than 2 × 1047 bits per second per gram of its mass," which means that a hypothetical supercomputer the size of the earth (= c. 6 × 1027 grams) grinding away for as long as the earth has existed (= about 1010 years, with c. 3.14 × 107 seconds/year) can have processed at most 2.56 × 2092 bits, which number is known as Bremermann's Limit.

This turns out to be true for our three spatial dimensions: mass, energy, and even time itself. There is no briefer period than 10-43 seconds.

What makes them even more astonishing is that there is compelling evidence that the only time quanta ever manifest as particles is when we are looking at them.

and that time itself is a fourth physical dimension.

In the froth, space doesn't have a definite structure. It has various probabilities for different shapes and curvatures. It might have a 50 percent chance of being in one shape, a 10 percent chance of being in another, and a 40 percent chance of being in a third form. Because any structure is possible inside the singularity, we say the singularity is constructed from probabilistic foam, or quantum foam. Quantum gravity governs the probabilities for the various foam structures.

This three-dimensional froth even produces tunnels and wormlike tubes commonly depicted in embedding diagrams for quantum froth. The connecting bridges in the foam correspond to wormholes between different universes or between different places in the same universe.

Until computers and robots make quantum advances, they basically remain adding machines: capable only of doing things in which all the variables are controlled and predictable.

Because the theory of quantum mechanics could explain all of chemistry and the various properties of substances, it was a tremendous success. But still there was the problem of the interaction of light and matter.

If I take the theory as we have it now, literally, I would conclude that extra dimensions really exist. They're part of nature. We don't really know how big they are yet, but we hope to explore that in various ways.

The quantum world is still very mysterious, still seemingly very powerful, and I'm definitely attracted to the mysterious and the unknown and just the vastness of what my imagination puts on it.

The uncertainty principle refers to the degree of indeterminateness in the possible present knowledge of the simultaneous values of various quantities with which the quantum theory deals; it does not restrict, for example, the exactness of a position measurement alone or a velocity measurement alone.

The uncertainty relation does not refer to the past; if the velocity of the electron is at first known and the position then exactly measured, the position for times previous to the measurement may be calculated.

The verbal interpretation, on the other hand, i.e. the metaphysics of quantum physics, is on far less solid ground. In fact, in more than forty years physicists have not been able to provide a clear metaphysical model.

Mindfulness and mental effort would then be understood as a way of using attention to control brain state by means of the Quantum Zeno Effect.

This statement was tremendously gratifying because it stated, from a physicist's perspective, what seemed to me the essential core of all my OCD work: that effort itself is the key to altering one's brain function. Stapp's insight was that quantum theory naturally allows for the direct influence of mental effort on the function of the brain. It thus makes mental effort and its effect on attention a primary causal agent.

This is the textbook position on quantum mechanics and the nature of reality: that the Cartesian separation of mind and matter into two intrinsically different substances is false.

If there is to be a resolution to the mystery of how mind relates to matter, it will emerge from explaining the data of the human brain in terms of these laws-laws capable of giving rise to a very different view of the causal efficacy of human consciousness. Quantum mechanics makes it feasible to describe a mind capable of exerting effects that neurons alone cannot.

For quantum theory elegantly explains how our actions are shaped by our will, and our will by our attention, which is not strictly controlled by any known law of nature.

The role of observation in quantum physics cannot be emphasized too strongly. In classical physics, observed systems have an existence independent of the mind that observes and probes them. In quantum physics, however, only through an act of observation does a physical quantity come to have an actual value.
