１８　Uncertainty principle【What is the Universe？】Dialogue with the Universe

Introduced first in 1927, by the German physicist Werner Heisenberg, it states that the more precisely the position of some particle is determined, the less precisely its momentum can be known, and vice versa.
You can answer only according to probability on the level of quantum.

○The formal inequality relating the standard deviation of position σx and the standard deviation of momentum σp
　　σｘσｐ≧ｈ
：No matter how improve the accuracy of the measurement, the product of the standard deviation of the position and momentum is greater than h.
：One is uncertain when you try to confirm the other.
・ｘ：position、ｐ：momentum
・h：Planck constant（6.626×10^-34 J・s）

○In the case of energy and time
　　σＥσｔ≧ｈ
：Beating only a little law of conservation of energy, it may be borrowed energy.
※However it must return as fast as borrow a lot.
・Ｅ：energy、ｔ： time
