People presume we've been somehow monitoring the entire sky at all frequencies, all the time, but we haven't yet been able to do any of those things. The fact is, all the SETI efforts to date have only closely examined a couple thousand nearby stars, and we're only just now learning which of those might have promising planets.

While NASA talks about 'Are we alone?' as a number one question, they are putting zero money into searching for intelligent life. There's a big disconnect there.

No company is hiring anyone to search for messages from aliens. Most people don't seem to think there's much benefit to it. The lack of interest is, I think, because most people don't realize what even a simple detection would really mean.

Right now, there could well be messages from the stars flying right through this room. Through you and me. And if we had the right receiver set up properly, we could detect them. I still get chills thinking about it.

Manufacturing doesn't just mean building cars and metal-bashing; it includes making pharmaceuticals and hi-tech electronics. A crucial part of the process is the research and development that allows better and greener products to come to market. Britain has traditionally had a strong science and engineering base.

Today, blood work and science are able to provide more of a movie of your health, identifying trends before they become an issue.

Spiderman was my favorite comic book character growing up. I'm a geek, so I love the fact Peter Parker is into science. And I gravitate towards short guys. I'm 5' 9"" now, but in junior high, I got picked on because I was 4' 8"".

So the history of discovery, particularly cosmic discovery, but discovery in general, scientific discovery, is one where at any given moment, there's a frontier. And there tends to be an urge for people, especially religious people, to assert that across that boundary, into the unknown, lies the handiwork of God. This shows up a lot.
