On October 24, 1992 a new voice took the helm at CBC's already venerable science program. And three decades and some 7000 interviews later, Bob McDonald is ready to look back - while still looking forward. We celebrated Bob's 30th anniversary with a show recorded in front of a live audience at the Ontario Science Centre in Toronto, where Bob began his career as a science communicator half a century ago. The event was hosted by Tapestry's Mary Hynes, as Bob was a guest on Quirks for the first time. We looked back at Bob's career, and some of the big stories in science he covered over the years, with appearances by special guests including retired Canadian astronaut Chris Hadfield, Nobel prize winner Art McDonald, and a whole family of friends and former guests on the program. It was a great evening of reminiscences and storytelling, with one eye on the past, but, as always with Quirks & Quarks, another on the future. ** This podcast contains bonus material not included in the radio broadcast.
