This is part two of the second podcast dialogue we are airing with renowned astrophysicist, Astronomer Royal, and former President of the Royal Society, Lord Martin Rees. The first time I sat down with Martin for the Podcast we discussed his life in science, and topics ranging from the state of modern cosmology to the potential conflicts between science and religion (which he views as minimal, and I don’t). Martin’s thinking, and his expertise, go far beyond these topics however. Based on his experience at the Royal Society, as an elected member of the House of Lords, and working with the Center for Existential Risk at Cambridge, Martin has thought carefully about the challenges we face as a society in the 21st century, and how science can be marshaled to help us address these challenges. He has written a new book on the subject called If Science is to Save Us. I thought it would be useful and interesting to sit down with Martin to discuss the ideas he raises there, and our conversation turned out to be so wide-ranging that we are presenting it in two separate episodes of the podcast. I am sure you will find his thoughtful and incisive comments both provocative and inspiring. As always, I benefitted greatly from my conversation with him, and I hope you do as well.
