George Dyson – historian, boat maker, and volunteer Staff Historian at Radiant Earth – returns to discuss Fred Hoyle's The Black Cloud. We discuss the cultural conflicts that arise between scientists and politicians, the limits of human language, human-incomprehensible modes of communication, the inevitable benefits of creating new observing instruments, alien consciousness, and the perils of simplified science.
