I'm not creating the universe. I'm creating a model of the universe, which may or may not be true.

Our hypotheses are initially rooted in theoretical consistency and elegance, but...ultimatel y it is experiment not rigid belief that determines what is correct.

I had this illusion that if I kind of dressed badly that I wouldn't stand out. You know, so I actually went out of my way to not look different to the extent I could.

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

Probably if you look like Tyra Banks, it probably is hard, even if you are really smart, for people to take - it surprises some.

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.

Scientists actively approach the door to knowledge—the boundary of the domain of what we know. We question and explore and we change our views when facts and logic force us to do so. We are confident only in what we can verify through experiments or in what we can deduce from experimentally confirmed hypotheses.
