" Heisenberg’s uncertainty principle, people are often confused by it. Heisenberg stated that both the position and velocity of a particle cannot simultaneously be known. You measure one, the other will always remain uncertain. The observation affects that which is observed. This is where people confuse the issue. It’s not the act of observation which makes things inherently uncertain - it’s the system itself which is uncertain. We blame it on us, the observers, but this is merely a convenient excuse, for the uncertainty is actually built into the world. A particle can never have two definite attributes - direction and position. If your define one, the other fades into indetermination. And so: there is no way to know everything. You must choose your knowledge. "
