"Search for Extraterrestrial Intelligence."

and when I tell people that at a cocktail party, they usually

look at me with a mildly incredulous look on their face.

I try to keep my own face somewhat dispassionate.

Now, a lot of people think that this is kind of idealistic,

but I just want to talk to you a little bit about why I think

that the job I have is actually a privilege, okay,

and give you a little bit of the motivation for my getting into

this line of work, if that's what you call it.

I was working there collecting data for my thesis.

Now, it's kinda lonely, it's kinda tedious, just collecting data,

so I would amuse myself by taking photos at night

because, you know, it, at night, I would be the only hominid

The observatory had just acquired at new book,

by the name of Joseph Shklovsky, and then expanded

and translated and edited by a little-known

Cornell astronomer by the name of Carl Sagan.

and at three in the morning I was reading this book

and it was explaining how the antennas I was using

to measure the spins of galaxies could also be used

to communicate, to send bits of information

Now, at three o'clock in the morning when you're all alone,

haven't had much sleep, that was a very romantic idea,

but it was that idea, the fact that you could in fact

that appealed to me so much that 20 years later I took a job

at the SETI Institute. Now, I have to say

that my memory is notoriously porous, and I've often

wondered whether there was any truth in this story,

or just, you know, misremembering something,

but I recently just blew up this old negative of mine,

the Shklovsky and Sagan book underneath that

All right. Now, the idea for doing this, it wasn't very old

The idea dates from 1960, when a young astronomer

by the name of Frank Drake used this antenna

in West Virginia, pointed it at a couple of nearby stars

Actually it did, but it turned out to be the U.S. Air Force,

which doesn't count as extraterrestrial intelligence. (Laughter)

But Drake's idea here became very popular because it

was very appealing — and I'll get back to that —

and on the basis of this experiment, which didn't succeed,

In fact, we don't know about any life beyond Earth,

but I'm going to suggest to you that that's going to change

rather soon, and part of the reason, in fact,

the majority of the reason why I think that's going to change

This is the Allen Telescope Array, about 350 miles

to search for E.T., and the electronics have gotten

This is Frank Drake's electronics in 1960.

This is the Allen Telescope Array electronics today.

Some pundit with too much time on his hands

has reckoned that the new experiments are approximately

a hundred trillion times better than they were in 1960,

That's a degree of an improvement that would look good

But something that's not appreciated by the public is,

in fact, that the experiment continues to get better,

This is a little plot, and every time you show a plot,

you lose 10 percent of the audience. (Laughter)

But what I plotted here is just some metric

In other words, we're looking for a needle in a haystack.

We know how big the haystack is. It's the galaxy.

But we're going through the haystack no longer

In fact, those of you who are still conscious
