Impossibility : The Limits of Science and the Science of Limits

Barrow looks at what limits there might be to human discovery, and what we might find, ultimately, to be unknowable, undoable, or unthinkable. that any Universe complex enough to contain conscious beings will contain limits on what those beings can know about their Universe; that what we cannot know defines reality as surely as what we can know.

What can we never do? Barrow looks at what limits there might be to human discovery, and what we might find, ultimately, to be unknowable, undoable, or unthinkable. Science is a big success story, but where will it end? And, indeed, will it end? Weaving together a tapestry of surprises, Barrow explores the frontiers of knowledge. We find that the notion of ''impossibility'' has played a striking role in our thinking. Surrealism, impossible figures, time travel, paradoxes of logic and perspectives - all stimulate us to contemplate something more than what is. Using simple explanations, it shows the reader that impossibility is a deep and powerful notion; that any Universe complex enough to contain conscious beings will contain limits on what those beings can know about their Universe; that what we cannot know defines reality as surely as what we can know.
