You could think of the galaxy as a sort of stove with lots of pots on it, and the pots are the interstellar medium, like a chicken broth getting stronger with every reduction. Every time a supernova goes off and sends its heavy elements out into the interstellar medium, we cook up a stew that's better and better for solar systems and life.

If I should have a daughter, instead of 'Mom,' she's gonna call me 'Point B,' because that way she knows that no matter what happens, at least she can always find her way to me. And I'm going to paint solar systems on the backs of her hands so she has to learn the entire universe before she can say, 'Oh, I know that like the back of my hand.'

I've had experiences in my life that leave no doubt in my mind about the fact that God exists. I'm quite willing to debate people who don't think so because I want them to explain to me how did our solar system get so organized and how is the universe so complex and yet well-organized that we can predict 70 years hence when a comet is coming?

Already renewable energy advocates are noting that the 42 miles of above-ground right-of-way between Yosemite and the city could be fitted with enough solar panels to generate at least 40 megawatts per year - a proposal the San Francisco Public Utilities Commission has never seriously considered because they currently aren't required to do so.

I used to be a strong believer that we would eventually colonize the solar system the way it's been done in science fiction many, many times: bases on the moon, Mars colonized, move out to the outer planets, then we go to the next solar system and build a colony there. I don't know now - I'm not as convinced that's the way it's going to pan out.

Hydroelectric dams remain the way many poor countries gain access to reliable electricity, and both solar and wind might be worthwhile in some circumstances. But there is nothing in either their history or their physical attributes that suggests solar and wind in particular could or should be the centerpiece of efforts to deal with climate change.
