The information you get from social media is not a substitute for academic discipline at all.

You start doing the addictive behavior to feel good and then your receptors get overloaded with dopamine, then you stop doing the addictive thing and some of the receptors have shut down and you don't have enough dopamine to feel good. So then you feel bad and go back to the addictive behavior to get more dopamine. The strange thing is that it works with what we think of as uppers and downers and whatever you call gambling - sidewaysers.

I say to the grown-ups, 'If you want to deny evolution and live in your world that's completely inconsistent with everything we've observed in the universe that's fine. But don't make your kids do it.'

There's nothing I believe in more strongly than getting young people interested in science and engineering, for a better tomorrow, for all humankind.

From an evolutionary standpoint you can't just wipe everything out and start over, and I don't think you can do it in the school system either.

Promoting a religious agenda that is to apply to every citizen is inconsistent with our laws in the US. It seems to me that your community and mine can live and work together without conflict.

To leave the world better than you found it, sometimes you have to pick up other people's trash.
