Dreams about the future are always filled with gadgets.

Dinosaurs are extinct today because they lacked opposable thumbs and the brainpower to build a space program.

You can't have people making decisions about the future of the world who are scientifically illiterate. That's a recipe for disaster. And I don't mean just whether a politician is scientifically literate, but people who vote politicians into office.

I like to believe that science is becoming mainstream. It should have never been something that sort of geeky people do and no one else thinks about. Whether or not, it will always be what geeky people do. It should, as a minimum, be what everybody thinks about because science is all around us.

The problem is not scientifically illiterate kids; it is scientifically illiterate adults. Kids are born curious about the natural world. They are always turning over rocks, jumping with two feet into mud puddles and playing with the tablecloth and fine china.

Some asteroids have us in their sights. Be nice to sort of go near them and find out what they're made of, possibly tag their ears so they're always broadcasting to us their location. In case one of their trajectories head straight for us, we'll know well in advance to do something about it.
