Aside from communications satellites, space is devoid of industry.

Science is not just there for technology. It's part of what addressing who you are in the universe and understanding your place in the cosmos. Good art, good literature, good music - all of that is for that and science is a part of it.

Empty space is a boiling, bubbling brew of virtual particles that pop in and out of existence in a time scale so short that you can't even measure them.

At the heart of quantum mechanics is a rule that sometimes governs politicians or CEOs-as long as no one is watching, anything goes.

The really important thing is learning how to sceptically question and rely on empirical evidence.

Teaching and writing, to me, is really just seduction; you go to where people are and you find something that they're interested in and you try and use that to convince them that they should be interested in what you have to say.
