Impossibility The Limits of Science and the Science of Limits

JOHN D. BARROW

Perhaps it's a harbinger of the end of science that so much attention is being paid to the impossible. In Impossibility, astronomer John D. Barrow outlines a maturation pattern for areas of deep human inquiry that includes an adolescence of exciting discoveries, new formulas, and unusual predictions. As science has matured, our confidence in it has grown. We expect that science has answers, that its predictive powers are mostly accurate. But what happens when the science gets old? Oddly enough, it seems to have started trying to find the end of its own usefulness--its formulas "predict that there are things which they cannot predict, observations which cannot be made, statements whose truth they can neither affirm nor deny."

Barrow's book is a fairly tough read, delving into topics as varied as theology, art, mathematics, and cosmology in its quest to define impossibility. But for those who have noticed that, "Scientists seem no longer content merely to describe what they have done or what Nature is like; they are keen to tell their audience what their discoveries mean for an ever-widening range of deep philosophical questions," Impossibility is an intriguing look at the evolution of our thoughts on knowing everything. Without limits, there would be no science, and though our imaginations may roam freely through the realms of impossibility, we may find in the end that "what cannot be known is more revealing than what can." --Therese Littleton
