Entanglement
Feb. 16th, 2004 08:41 pmRecently finished reading the book 'Entanglement' by Amir D. Aczel. Food for thought:
"Entanglement teaches us that our everyday experience does not equip us with the ability to understand what goes on at the micro-scale, which we do not experience directly.
Greenstein and Zajonc (The Quantum challenge) give an example demonstrating this idea. A baseball hit against a wall with two windows cannot get out of the room by going through BOTH windows at once. This is something every child knows instinctively. And yet an electron, a neutron, or even an atom, when faced with a barrier with two slits in it, will go through both of them at once. Notions of causality and the impossibility of being at several locations at the same time are shattered by the quantum theory. The idea of superposition- of "being at two places at once"- is related to the phenomenon of entanglement. But entanglement is even more dramatic, for it breaks down our notion that there is a meaning to spatial separation. Entanglement can be described as a superposition principle involving two or more particles. Spatial separation as we know it seems to evaporate with respect to such a system. Two particles that can be miles, or light years apart may behave in a concerted way: what happens to one of them happens to the other one instantaneously, regardless of the distance between them."
