Adrian Berry, dubbed "the Dean of English science writers," extrapolates from his wide knowledge to inquire into the possibilities of far-space exploration.

Berry writes with lucidity and humor, demonstrating not only a broad spectrum of scientific knowledge but also an intimacy with the works of science fiction writers. His predictions are always rooted in scientific fact.
