Demons is discussed. In this sequel to The Da Vinci Code a bomb usinganti-matter produced at the particle physics laboratory CERN is used toterrorize the Vatican. The lecture considers questions such as is ananti-matter bomb viable, how does it compare to conventional nucleardevices and can anti-matter be used as a source of electrical power?Examples of more peaceful real-world uses for anti-matter from within thefields of medicine and fundamental physics research are also explored.
