'Boldly going where hundreds have gone before' does not make headlines.

UFO (Unidentified Flying Object)sightings are not higher among amateur astronomers than they are in the general public. In fact, they're lower. You say, why is that so? Well, because we know what the hell we're looking at!

Everything we do understand about the universe - the periodic table of elements, Einstein's laws, Newton's laws, all of chemistry, all of biology - that's 4 percent of the universe. We got to the moon on the 4 percent we do understand. We landed on Mars on the 4 percent we do understand. So the day we crack the nut of the rest of that 95 percent... Oh my gosh.

If you look at the history of unexplained phenomena that was first explained by spiritual, mystical forces, the track record is not very good for the mystical, magical explanations to survive against more quote "mundane" physical explanations.

If Pizza sizes were given in area not diameter, you'd see instantly that a 7 inch is less than half the size of a 10 inch pie

No doubt, the most challenging class of questions in science is the origin of things.

I try to show the public that chemistry, biology, physics, astrophysics is life. It is not some separate subject that you have to be pulled into a corner to be taught about.
