Helpful quantum mechanics analogy.

[ollypenrice]

Rather than trying to visualize particles interacting within the atom, it is better to think of them as being like chess pieces. They might be made of wood or ivory, large or small, they might even just be symbols noted on slips of paper, but this doesn't matter. What matters is the way they interact with each other.

I though this was a great analogy. The above is not a quotation, just a paraphrase, and it comes from one who was certainly not famous as a good communicator, but whose competence in quantum mechanics is well and truly beyond any doubt: Paul Dirac.
