There has been a great gulf in psychological thought between the perception of space and objects on one hand and the perception of meaning on the other.

What a thing is and what it means are not separate, the former being physical and the latter mental as we are accustomed to believe.

Psychology is still trying to explain the perception of the position of an object in space, along with its shape, size, and so on, and to understand the sensations of color.

The meaning or value of a thing consists of what it affords.

I've had young women come to me and say that before they watched 'Voyager' it didn't really occur to them that they could be successful in a higher position in the field of science; girls going to MIT, girls pursuing astrophysics with a view to a career in NASA.

I'm a big believer that science is part of a larger cultural thing. Science is not all by itself.

What I love about sci-fi is that every generation's films are based on what we know at that point in time. We make movies about the future but it's always based on what we have. Then as science grows and we discover new things, so do our ideas. You know?

The bedrock nature of space and time and the unification of cosmos and quantum are surely among science's great 'open frontiers.' These are parts of the intellectual map where we're still groping for the truth - where, in the fashion of ancient cartographers, we must still inscribe 'here be dragons.'
