Skepticality #071 - Dr. Karl Explains it All - Interview: Dr. Karl Kruszelnicki

This week on Skepticality, science educator and skeptic Michael McRae interviews one of Australia's most recognizable scientists, Dr. Karl Kruszelnicki, who is known to most Aussies simply as "Dr. Karl." Dr. Karl is the Julius Sumner Miller Fellow at the University of Sydney, as well as a proud recipient of the Ig Nobel prize.  He is also a popular science commentator on radio and television, and a bestselling author of 26 books—including his most recent, Please Explain, which gives the facts on everything from why we yawn, to the history of near death experiences.
