In physics, one of the most exciting areas is in nanotech. With computers exhausting the power of silicon, Silicon Valley could become a Rust Belt, unless we can find replacements, such as quantum computers and molecular computers. To be a leader in any field, one has to have a great imagination. Sure, we have to know the basics and fundamentals. But beyond that, we have to let our imagination soar.

In general, the larger the breeding population, the slower the rate of evolution.

I think a colony in space will take much longer than sci fiction writers think. It costs $10,000 to put a pound of anything into near earth orbit. That is your weight in gold. It costs about $100,000 a pound to put you on the moon. And it costs $1,000,000 a pound to put you on Mars.

Being a physicist, not a philosopher, I have devised an entirely new theory of consciousness, allowing one to numerically calculate the level of consciounsess of humans and even animals.

All kids are born geniuses, but are crushed by society.

To a physicist, we have the 'I' word, the I-word is 'impossible.' That's dangerous.

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.
