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.

I remember the first day of school my first year in the classroom. My stomach churned with a mixture of excitement and anxiety. Could I do the job? Could I connect with the kids? Will there be the chemistry to build relationships and get the job done, or will I totally flop?

There is a science to managing high tech businesses, and it needs to be respected. One of them is that in technology businesses, leadership is temporary. It's constantly recycling. So the asset has limited lifetime.

When I was a graduate student in computer science in the early 2000s, computers were barely able to detect sharp edges in photographs, let alone recognize something as loosely defined as a human face.

Science may never come up with a better office communication system than the coffee break.
