Why is uncertainty principle said to be a very strange thing? "Heisenberg uncertainty principle states that locating a particle in a small region of space makes the momentum of the particle uncertain; and conversely, that measuring the momentum of a particle precisely makes the position uncertain." Isnt it just a limitation of our measuring techniques? I remember reading some scientist exclaiming that one who is not shocked by this principle has not understood it. But I am not at all shocked. Can anyone please help?
