It makes me think of a recent discussion I had with a friend about energy versus matter, flow versus stasis, wave versus particle. The first is related in Einstein's famous equation:
Now isn't that cooler than bullets, if not the way out from violence? Maybe we can't stop bullets physically once they're fired, but there's a lot of training we can do (and energy we can tap into!) before someone pulls the trigger.
May we beat swords into plowshares with our minds, hearts and hands.
