In string theory, all particles are vibrations on a tiny rubber band; physics is the harmonies on the string; chemistry is the melodies we play on vibrating strings; the universe is a symphony of strings, and the "Mind of God" is cosmic music resonating in 11 dimensional hyperspace.

Time travel and teleportation will have to wait. It may take centuries to master these technology.

Well, Congress gave us a billion dollars to dig the hole, this gigantic hole. Bigger, much bigger than the hole in Geneva, Switzerland. Then they canceled the machine and gave us a second billion dollars to fill up the hole. Two billion dollars to dig a hole and fill it up. That is the wisdom of the United States Congress and it really makes you wonder: Is there intelligent life on the Earth? Certainly not in the United States Congress.

The energy necessary to create a wormhole or to wrap time into nuts is incredible. It's not for us. It's maybe for our descendants who have mastered the energy of this technology. So if one day, somebody knocks on your door and claims to be your great great great great granddaughter, don't slam the door.

We have the media, which is such a waste in the sense that you can actually feel your IQ get lower as you watch TV.

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 don't. We've had three technological revolutions that have changed the course of human history, all driven by physics. In the first, the industrial revolution, physicists developed Newtonian mechanics and thermodynamics, which gave us the steam engine and machine power. The second technological revolution was the electricity revolution. That gave us radio, television, and telecommunications. Then, physicists developed the laser and the transistor.
