The most complex object in the known universe: brain, only uses 20 watts of power. It would require a nuclear power plant to energize a computer the size of a city block to mimic your brain, and your brain does it with just 20 watts. So if someone calls you a dim bulb, that's a compliment.

I am a figure skater, which helps me appreciate Newton's theory of mechanics.

There are so many wonders awaiting us. If we can upload memories, then we might be able to combat Alzheimers, as well as create a brain-net of memories and emotions to replace the internet, which would revolutionize entertainment, the economy, and our way of life. Maybe even to help us live forever, and send consciousness into outer space.

Science is the engine of prosperity. But you'd never know it, listening to some of the politicians. They're lawyers and businessmen, not scientists. Lawyers and businessmen massage wealth; they don't create it.
