There can sometimes be this fear among laypeople: 'I don't understand everything in science perfectly, so I just can't say anything about it.' I think it's good to know that we scientists are also confused some of the time.

Creativity is essential to particle physics, cosmology, and to mathematics, and to other fields of science, just as it is to its more widely acknowledged beneficiaries - the arts and humanities.

People who dismiss science in favor of religion sometimes confuse the challenge of rigorously understanding the world with a deliberate intellectual exclusion that leads them to mistrust scientists and, to their detriment, what they discover.

It's hubris to think that the way we see things is everything there is.
