How to pronounce "rails"

so they pick up these kinds of activities.

This has huge organizational implications

for very large areas of life.

Take astronomy as an example,

which Yochai has already mentioned.

Twenty years ago, 30 years ago,

only big professional astronomers

with very big telescopes could see far into space.

And there's a big telescope in Northern England called Jodrell Bank,

and when I was a kid, it was amazing,

because the moon shots would take off, and this thing would move on rails.

Now, six

amateur astronomers, working with the Internet,

with Dobsonian digital telescopes --

which are pretty much open source --

with some light sensors

developed over the last 10 years, the Internet --

they can do what Jodrell Bank could only do 30 years ago.

So here in astronomy, you have this vast explosion

of new productive resources.

The users can be producers.
