Does anyone know the meaning of quantum scale in quantum mechanics?
Translation to Chinese would be great!
'quantum scale' is a scale so small that our ability to measure the position of something is measured by a probability. For a given size (scale) like 1 angstrom or so, we can only make a best guess about where a moving particle like an electron may be. At this 'quantum scale' level of measurement, there is no real difference between a partical in motion and a wave that stands still.
