HEISENBERG’S UNCERTAINTY

In my post on FREE WILL, I talked about, how quantum mechanics adds a little uncertainty in the outcome of an experiment. This was first pondered upon by Heisenberg, who said that it is impossible to know the exact position and the exact velocity (or momentum) of a quantum particle simultaneously.

Think of it this way. The reason we “see” is because light (or photons) bounce off of it and enter our eye. For big objects this doesn’t pose a problem because a photon is tiny and hitting something with a photon won’t cause it to move. But imagine a very small particle, like an electron. If we hit an electron with a photon, the collision would cause the electron to move. So, we wouldn’t know with exact certainty, where the electron was, or how fast was it moving. This types up with my Acts of Observation post as well. Interaction with an experiment causes the experiment to change.

The uncertainty principle is a fundamental of Quantum Mechanics. It explains everything from why atoms are stable to why vacuum in not actually empty space. Also, it is the source of much humour.
