Today's clunky smart glasses will be replaced by smart contact lenses. We'll command them by voice, blinking, or even thinking, to interact visually in 3-D with the Internet.

What do oil company executives, vampires and NASA bureaucrats all have in common? They fear solar energy.

We need an enduring, robust theory of education. Now, it seems education careens from one fad to another and often back again. I think that with better education and students willing to put in the 10,000-hours to become expert, we could develop better science professionals, even theoretical physicists.

I realized very early in life what my abilities and limitations were, and foreign languages was definitely one of my limitations. With strenuous effort, I just barely passed my French class at Harvard so I could graduate.

We need more concept-development and active involvement, less tuning forks, pulleys, and friction formulas - students know they'll never use those. They need more study of outer space and DNA. They need more exciting teaching, more fair-minded encouragement, more career guidance, more mentorship. Both students and teachers need more feedback. It would help if we stopped protecting bad teachers - It's very difficult to get rid of even sexual perverts let alone just bad teachers.

Once again, my colleague Stephen Hawking has upset the apple cart. The event horizon surrounding a black hole was once though to be an imaginary sphere. But recent theories indicate that it may actually be physical, maybe even a sphere of fire. But I don't trust any of these calculations until we have a full-blown string theory calculation, since Einstein's theory by itself is incomplete.

There is so much noise on the Internet, with would-be prophets daily haranguing their audience and megalomaniacs trying to push bizarre ideas, that eventually people will cherish a new commodity: wisdom.
