What was done is measure directly, with exquisitely sensitive instruments, gravitational waves predicted about 100 years ago by Albert Einstein. These waves are a new way to study the universe and are expected to have significant impact on astronomy and astrophysics in the years ahead.

I thought that there must be an easier way to explain how a gravitational wave interacts with matter: If one just looked at the most primitive thing of all, 3D floating masses out in space, and look at how the space between them changed because of the gravitational wave coming between them.

We were looking almost one-tenth of the way to the edge of the universe. We're planning to use the facilities we have to make improvements by another factor of 10... a strain sensitivity that is 10 times smaller. This means looking 10 times further out into the universe.

You know the Einstein waves can be thought of as a distortion of space and time. But the way we see it, we see it as a distortion of space. And space is enormously stiff. You can't squish it; you can't change its dimensions so easily.

It's unfair to the hard-core stay-at-home moms to pretend you're able to have an amazing body by chasing around your kids.

My father loved people, children and pets.

Whatever our bedtime was as kids, we could stay up an extra half hour if we were reading. My parents didn't care as long as I was under the spell of a Stephen King or a Douglas Adams. Now I read in bed. I read at work. I read standing in line. It's like, 'Hello, my name is Nathan and I am a reader.'

Parenting girls makes you quite gender-conscious - it's almost impossible to fight the power of pink. It's not such a terrible thing to want to be a princess when you're five, but it would be nice if there were some other options.
