I hope we find evidence of dark matter in the lab and in outer space. This would go a long way to proving the correctness of string theory, which is what I do for a living. That is my day job. So string theory is a potentially experimentally verifiable theory.

We should explore new ways to drive down the cost of space travel. instead of costly booster rockets, maybe we should think of laser/microwave driven rockets, or space elevators. Until then, the cost of space exploration will limit our ability to explore the universe.

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.

We have learned more about the brain in the last fifteen years than in all prior human history, and the mind, once considered out of reach, is finally assuming center stage.

In fact, all of us have a piece of Chernobyl in our bodies going back to 1986.

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.

The brain weighs only three pounds, yet it is the most complex object in the solar system.
