In the early 1990s, I was signed as a singer to the same label as Robyn. She was in her early teens, and I was in my twenties, so we didn't hang out, but our paths crossed so many times that we slowly got to know each other and became friends.

I began my career as a recording artist, and eventually I started directing my own music videos.

I grew up all over the world. My dad was a doctor but not a career-type doctor. He was very curious, so he took the whole family and moved to Miami in the '70s, and we lived there for a couple of years. Then we continued like that and lived in various places around the world.

Building a cast is a card house. They lean on each other, provide for each other, and take from each other.

While a lab director can get done the things that he regards as important, he has the more important job of bringing out the best ideas of the broader scientific community. I learned this early in my career while I was leading the construction of the SPEAR facility.

Traditional scientific method has always been at the very best, 20 - 20 hindsight. It's good for seeing where you've been. It's good for testing the truth of what you think you know, but it can't tell you where you ought to go.

Theories, for me, are just about freeing your mind. It doesn't mean the theory is going to work like a scientific theory works. It's about freeing your mind and making you think a different way.

There has to be chemistry in a duet, but if you go beyond the point of friendship and attraction, you lose something.
