An aura of glamorous secret attaches to the thought of quantum entanglement, and also to the (somehow) connected claim that quantum concept needs “many worlds.” Yet in the end individuals are, or ought to be, scientific suggestions, with down-to-earth meanings and concrete implications. In this article I’d like to reveal the concepts of entanglement and quite a few worlds as simply just and plainly as I know how. I. Entanglement is often regarded as a uniquely quantum-mechanical phenomenon, but it is not. In point, it is enlightening, nevertheless considerably unconventional, to take into account a straightforward non-quantum (or “classical”) version of entanglement first. This permits us to pry the subtlety of entanglement itself aside from the normal oddity of quantum concept.
