 Write a Review of CBC Radio: Quirks and Quarks Segmented Show Podcast
My favourite podcast!, April 22, 2006
Reviewer: Joanna
This is a very interesting, well-produced podcast that also airs on Terrestrial radio. Bob Macdonald is a friendly and personable host and the weekly show covers a wide range of science topics of interest to the average person. I love how they get in more than one expert on most topics, in order to present a well-rounded view. You can also download the whole show as one file, or just individual segements. Archives on the website go back several years! This is a show well worth a listen. I am addicted!
