The supermoon is a 16-inch pizza compared with a 15-inch pizza. It's a slightly bigger moon; I ain't using the adjective 'supermoon.'
As the area of our knowledge grows, so too does the perimeter of our ignorance.
I lose sleep at night wondering whether we are intelligent enough to figure out the universe. I don't know.
We didn't go to the moon to explore or because it was in our DNA or because we're Americans. We went because we were at war and we felt a threat.
For me, I am driven by two main philosophies: know more today about the world than I knew yesterday and lessen the suffering of others. You'd be surprised how far that gets you.
I can't tell you how many people say they were turned off from science because of a science teacher that completely sucked out all the inspiration and enthusiasm they had for the course.
