Uncertainty" is NOT "I don't know." It is "I can't know." "I am uncertain" does not mean "I could be certain. — Werner Heisenberg Copy Share Image
In my paper the fact the XY was not equal to YX was very disagreeable to me. I felt this was the… — Werner Heisenberg Copy Share Image
The uncertainty relation does not refer to the past; if the velocity of the electron is at first known and the position… — Werner Heisenberg Copy Share Image
