John Horgan: I think of certain scientists as wise, even statesmanlike. They possess a quiet authority that makes you trust their judgment, and not just on scientific matters. Physicists Hans Bethe and Steven Weinberg come to mind, and so does cosmologist Martin Rees. Rees, who is based at the University of Cambridge and is Britain’s Astronomer Royal, has had an illustrious career, which you can read about here. In addition to his decades of contributions to astrophysics and cosmology, he has also spoken out on threats facing humanity.
