In 2008, the Amaz!ng Meeting 6 took on the theme “I, Skeptic”, exploring the role skeptics play in the modern, digital age. We are happy to present our keynote speaker from that meeting, astrophysicist Dr. Neil DeGrasse Tyson, who delivers a fiery defense of critical thinking and a skeptical worldview.
