Suite à l'interprétation que C.G. Jung ose tenter de son propre tirage du Yijing (article du 9 juin 2011 sur la synchronicité), voici comment la science y répondrait :
How does the universe know how to go from a state of indefiniteness before a measurement is made, to definiteness after? (p.62)
…There are two sorts of “random” processes. In one, the system is really deterministic, but you simply don’t have enough information, or can’t calculate fast enough, to figure out what’s going to happen. Take a coin flip, for example. If you wanted to call it in the air and knew the exact position, orientation, weighting, and spin of the coin, as well as the wind direction and speed, then in principle you could run those data through a computer to figure out how the coin will fall. We could repeat the experiment under nearly the same conditions again and again and get the same outcome. If we made a finely tuned robotic coin-flipping machine, we could make heads come up every time.
In practice, there is so much uncertainty with how a coin is held, how the air is blowing, how hard you flip the coin, and where you apply the pressure, that there is absolutely no practical way that you could do these calculations. That’s why the coin flip is the random number generator par excellence. Likewise, even though the sequence of cards or the landing of a roulette ball seem pretty random, at the end of the day it’s really more that we don’t know enough about the initial conditions… BUT COIN FLIPS ARE NOT ATOMS, AND SOMETHING VERY DIFFERENT HAPPENS WHEN WE TALK ABOUT RANDOMNESS ON THE SUBATOMIC SCALE. AT THAT EXTREME, THE UNIVERSE IS REALLY, TRULY RANDOM. (!!!) (p.77-78)
