Quotes About Macroscopic

Why are black holes so different from all other objects in the macroscopic Universe? Why are they, and they alone, so elegantly simple? If I knew the answer, it would probably tell me something very deep about the nature of physical laws. But I don't know.

An excellent definition can be found in the book Quantum Enigma by Bruce Rosenblum and Fred Kuttner: "Whenever any property of a microscopic object affects a macroscopic object, that property is 'observed' and becomes a physical reality." For example, when a microscopic photon hits the macroscopic screen in the double-slit experiment, then

In fact any experiment that measures a quantum effect is one in which the quantum effect is aligned with the behavior of some heavy, macroscopic object; that's how we measure it.

The black holes of nature are the most perfect macroscopic objects there are in the universe: the only elements in their construction are our concepts of space and time.

But, of course, that's just how the Earth operates—on a slightly larger scale.

Las teorías cuánticas han resultado ser notablemente precisas en la predicción de acontecimientos a dichas escalas, y también reproducen las predicciones de las viejas teorías clásicas cuando son aplicadas al mundo macroscópico de la vida corriente.

If information is lost in macroscopic black holes it should also be lost in processes in which microscopic, virtual black holes appear because of quantum fluctuations of the metric. One could imagine that particles and information could fall into these holes and get lost. Maybe that is where all those odd socks went.

The qubit acts as a bridge between the microscopic and the macroscopic worlds.

I think I'm more concerned with things that are very big and things that are very small than with all the stuff in between.

To the physicist – but only to him – I could hope to make my view clearer by saying: The living organism seems to be a macroscopic system which in part of its behaviour approaches to that purely mechanical (as contrasted with thermodynamical) conduct to which all systems tend, as the temperature approaches the absolute zero and the molecular disorder is removed.

Through the continued accumulation of detailed and reliable knowledge about elementary reactions, we will be in a better position to understand, predict and control many time-dependent macroscopic chemical processes which are important in nature or to human society.

The whole, tightly coupled system, at the moment of self-organization, begins to act upon its microscopic parts to stimulate further, often much more complex, synchronizations. A continuous stream of information begins flowing back and forth, extremely rapidly, between the macroscopic, ordered whole to the smaller microscopic subunits and back again (interoceptive) so that the self-organizing structure is stabilized, its newly acquired dynamic equilibrium actively maintained.

Newton's laws aren't fundamental, they are emergent; that is, they are what happens when quantum matter aggregates into macroscopic fluids and objects. It is a collective organizational phenomenon.

a) The probability wave for a macroscopic object is generally narrowly peaked. (b) The probability wave for a microscopic object, say, a single particle, is typically widely spread.

Rather than probability, one can speak of a measure of the disorder of the atoms, because the equivalent disordered states (for a given macroscopic state) are very many and the probability that one of them occurs is extremely high. We shall discuss this paper in detail in Chapter 6.

In the same paper Boltzmann was able to derive a proof of the irreversibility of macroscopic phenomena. It is the difference of scale between the objects that we observe in everyday life on the one hand, and molecules on the other hand, which explains this irreversibility through the laws of probability.

The entropy of the world in the far past appears very low to us. But this might not reflect the exact state of the world: it might regard the subset of the world' s variables with which we, as physical systems, have interacted. It is with respect to the dramatic blurring produced by our interactions with the world, caused by the small set of macroscopic variables in terms of which we describe the world, that the entropy of the universe was low.

A dolgok csak egymáshoz képest változnak. A világ alapszerkezetében nincs id?. Az id? múlásának érzete csupán közelítés, és csak a mi makroszkopikus mérettartományunkban érvényes.

The apparent determinism of the macroscopic world is due only to the fact that the microscopic randomness cancels out on average, leaving only fluctuations too minute for us to perceive in everyday life.

Someday, when the ultimate laws of physics are in our grasp, we may discover that the notion of time isn't actually essential. Time might instead emerge to play an important role in the macroscopic world of our experience, even if it is nowhere to be found in the final Theory of Everything.

Like the microscopic strands of DNA that predetermine the identity of a macroscopic species and the unique propertires of its members, the modern look and feel of the cosmos was writ in the fabric of its earliest moments, and carried relentlessly through time and space. We feel it when we look up. We feel it when we look down. We feel it when we look within.

The microscopic pieces were perfectly clear; the macroscopic behavior remained a mystery. The tradition of looking at systems locally—isolating the mechanisms and then adding them together—was beginning to break down.
