Physicists are interested in measuring neutrino properties because they tell us about the structure of the Standard Model, the well-tested theory that describes matter's most basic elements and interactions.

The standard model of particle physics describes forces and particles very well, but when you throw gravity into the equation, it all falls apart. You have to fudge the figures to make it work.

Harvard freshmen are smart, interested, and excited, and it's fun hearing their different perspectives and stuff that they will share.

There could be more to the universe than the three dimensions we are familiar with. They are hidden from us in some way, perhaps because they're tiny or warped. But even if they're invisible, they could affect what we actually observe in the universe.

I actually think I'm probably more interested in structure than most people who write screenplays, because I think about it.

There is real confusion about what it means to be right and wrong - the difference between what spiritual beliefs are and what science is.
