"particles"タグの名言

You never walk alone. Even the devil is the lord of flies.

A photon or an electron is not a thing, it is a description of a relationship.

The future of particle physics is not more particles instead moments in time.

There are no particles. There are only moments in time.

The true fundamental building blocks of the universe are not particles, but moments in time.

When left alone, quantum particles behave as multiple images of themselves (as waves, really), simultaneously moving through all possible paths in space and time. Now, again, why do we not experience this multitude around ourselves? Is it because we are probing things around us all the time? Why do all experiments that involve, say, the position of a particle make the particle suddenly be somewhere rather than everywhere? No one knows. Before you probe it, a particle is a wave of possibilities. After you've probed it, it is somewhere, and subsequently it is somewhere for ever, rather than everywhere again. Strange, that. Nothing, within the laws of quantum physics, allows for such a collapse to happen. It is an experimental mystery and a theoretical one. Quantum physics stipulates that whenever something is there, it can transform into something else, of course, but it cannot disappear. And since quantum physics allows for multiple possibilities simultaneously, these possibilities should then keep existing, even after a measurement is made. But they don't. Every possibility but one vanishes. We do not see any of the others around us. We live in a classical world, where everything is based on quantum laws but nothing resembles the quantum world.

The very small quantum world, it seems, is a mixture of possibilities. The quantum fields to which all particles belong are the sum of these possibilities and, somehow, one possibility is chosen out of all the existing ones just by seeing it, just by the very act of detecting it, whenever one tries to probe a particle's nature. Nobody knows why or how this happens.

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

Those who are not shocked when they first come across quantum theory cannot possibly have understood it.

In the world of the very small, where particle and wave aspects of reality are equally significant, things do not behave in any way that we can understand from our experience of the everyday world...all pictures are false, and there is no physical analogy we can make to understand what goes on inside atoms. Atoms behave like atoms, nothing else.
