I still will sit down at the piano and play when I am wrestling with something emotionally or just want to move into the musical world.

In this world, time has three dimensions, like space. Just as an object may move in three perpendicular directions, corresponding to horizontal, vertical, and longitudinal, so an object may participate in three perpendicular futures. Each future moves in a different direction of time. Each future is real. At every point of decision, the world splits into three worlds, each with the same people, but different fates for those people. In time, there are an infinity of worlds.

Unfortunately, public debates do not have much room for subtlety. The audience wants a quick thrust at your opponent, not a slow and convoluted series of moves. Whenever Obama uses subtleties in discussing a complex issue, he gets creamed.

The world is moving faster and faster, but where are we going?
