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.

I agree, along with Carl Sagan, that we should eventually become a two planet species. Life is too precious to place on a single planet.

We've done a miserable job of preparing people for today's world, let alone tomorrow's.

Hover boards, unfortunately, currently violate the laws of physics. Supermagnets exist, but they have to be cooled to near absolute zero, and they are extremely expensive. So Michael J. Fox's hover boards are not possible until we invent room temperature super conductors.

Our best shot at finding life in our solar system might be to look at the moons of Jupiter and Saturn. Mars, increasingly, looks like a dead planet. But the oceans beneath the ice cover of the moons of Jupiter and Saturn may actually have more liquid water than the oceans of Earth.

Chemistry is the melodies you can play on vibrating strings.

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.
