We've heard from many teachers that they used episodes of Star Trek and concepts of Star Trek in their science classrooms in order to engage the students.

Science fiction was never my thing. I have no interest in it.

I don't really see science fiction as fiction. I can imagine colonies on Mars and everything.

And I have lived since - as you have - in a period of cold war, during which we have ensured by our achievements in the science and technology of destruction that a third act in this tragedy of war will result in the peace of extinction.

From all this it follows what the general character of the problem of the development of a body of scientific knowledge is, in so far as it depends on elements internal to science itself.
