When I was in school I liked math because all the problems had answers. Everything else seemed very subjective.

I did not set out to explain the extinction of the dinosaurs. I'm a particle physicist, and I was actually thinking about dark matter along with some collaborators.

You might find it hard to imagine gravity as a weak force, but consider that a small magnet can hold up a paper clip, even though the entire earth is pulling down on it.

One of the nice things about math and science is it’s obvious, you get the answer or you don’t get the answer.

Scientific research involves going beyond the well-trodden and well-tested ideas and theories that form the core of scientific knowledge. During the time scientists are working things out, some results will be right, and others will be wrong. Over time, the right results will emerge.

Both religions and musicals work best with energetic and committed believers. Cynicism or detachment would have destroyed the magic - something true of religion, too.

Science is a combination of theory and experiment and the two together are how you make progress.
