In this deep dive into the history of science and war, and the strange but productive alliances that have been formed over the centuries—particularly those between astrophysicists and politicians, governments, military, and corporations—Neil deGrasse Tyson and Michael Shermer cover centuries of history and the many facets of science policy that have brought us to the modern world of space telescopes, GPS, and the Internet, along with guided missiles, nuclear weapons, and smart bombs delivered by drones. The conversation focuses primarily on Tyson’s new book, Accessory to War, co-authored with his long-time Natural History editor Avis Lang, which is a serious scholarly work on a monumentally influential topic. Shermer also challenges Tyson on the relationship between resource scarcity and war, and when scientists like Werner von Braun and Edward Teller go too far in developing weapons of mass destruction, when “scientists know sin.” Tyson is at his best when pushed to go deep on serious subjects like these. Don’t miss this fascinating discussion. Neil deGrasse Tyson is an astrophysicist, author, and the Frederick P. Rose Director of the Hayden Planetarium at the Rose Center for Earth and Space in New York City. He is the host of the Cosmos television documentary series, and of his wildly popular Startalk podcast and National Geographic television show. His books include Death by Black Hole, Origins, The Sky is Not the Limit, The Pluto Files, Space Chronicles, and Astrophysics for People in a Hurry, which has been on the New York Times bestseller list for 67 weeks.
