Science provides an understanding of a universal experience, and arts provides a universal understanding of a personal experience.

People always think of technology as something having silicon in it. But a pencil is technology. Any language is technology. Technology is a tool we use to accomplish a particular task and when one talks about appropriate technology in developing countries, appropriate may mean anything from fire to solar electricity.

Sciences provide an understanding of a universal experience, Arts are a universal understanding of a personal experience... they are both a part of us and a manifestation of the same thing... the arts and sciences are avatars of human creativity

As an astronaut, you have a very defined set of tasks to do. Those tasks may require you to work 60, 70 or 80 hours a week.

The difference between science and the arts is not that they are different sides of the same coin… or even different parts of the same continuum, but rather, they are manifestations of the same thing. The arts and sciences are avatars of human creativity.

I always knew I'd go to space.

Never be limited by other people's limited imaginations.
