I shook up the world, I shook up the world.

You want to do good things, and once you’ve done a couple of good things in a row, you think ‚Well gee, let’s not mess this up.‘ But I am lucky at this point that I have something I really love to do, and it completely holds my attention. I never feel frustrated by it.

What we hope ever to do with ease, we must learn first to do with diligence.

Before I lost my voice, it was slurred, so only those close to me could understand, but with the computer voice, I found I could give popular lectures. I enjoy communicating science. It is important that the public understands basic science, if they are not to leave vital decisions to others.
