I give a lot of public talks about the universe. Really. It's in my job description:

  • Astronomer. Check.
  • Study stuff in space. Check.
  • Give talks about universe. Check.

The combustion engine is dominant. In the United States, according to the latest estimates from the Census, more than 76 percent of us get to work alone in a car. The numbers are not quite as lopsided in some big cities, where public transit and other options are more widely available.
