For most people, the major hurdle in grasping modern insights into the nature of the universe is that these developments are usually phrased using mathematics.

For me it's been very exciting to contribute to the public's understanding of how rich and wondrous science is.

In my own research when I'm working with equations, I never feel like I really understand what I'm doing if I'm solely relying on the mathematics for my understanding. I need to have a visual picture in my mind. I'm constantly translating from the math to some intuitive mind's-eye picture.

There are many of us thinking of one version of parallel universe theory or another. If it's all a lot of nonsense, then it's a lot of wasted effort going into this far-out idea. But if this idea is correct, it is a fantastic upheaval in our understanding.

Learn computer science. It's extraordinarily helpful. I like recommending learning economics as well so they think in terms of business, they have rational frameworks for looking at the world, but yeah, computer science is an amazing way to get into, even if you want to be CEO, having a tech background is helpful.

When the state was going to tell you what your future would be, science fiction was irrelevant.

Today's preoccupation with physical theories of everything takes a wrong turn from the purpose of science - to question all things relentlessly. Modern physics has become like Swift's kingdom of Laputa, flying absurdly on an island above the earth and indifferent to what is beneath.

I was, from early on, interested in science. And my parents were very obliging about that. My father used to take me to the museum of natural history, and I knew much more scientific stuff early on. From the time I was 11 or 12, I wanted to be a mathematician.
