I like 'The Simpsons' quite a lot. I love the irreverent character of the whole show. It's great.

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.

You should never be surprised by or feel the need to explain why any physical system is in a high entropy state.

The idea that there could be other universes out there is really one that stretches the mind in a great way.

I can assure you that no string theorist would be interested in working on string theory if it were somehow permanently beyond testability. That would no longer be doing science.

I'd say many features of string theory don't mesh with what we observe in everyday life.

Most scientists like to operate in the context of economy. If you don't need an explanatory principle, don't invoke it.
