There's a little known method of solving the cube from this position that makes a good analogy with the effects of the strong nuclear force on particle symmetry.

I have a pristine cube, and I've just exchanged the stickers on the top edge cubie facing me. How do I solve it? So far, the only way I've been able to solve this one is to whack it in a particle accelerator and wait for the stickers to change color again...

Remove the edge piece from the cube framework, flip it and insert it back in (you've just turned an Up quark into a Down quark, or something like that.)
