Quirks & Quarks is the award-winning radio science program of the Canadian Broadcasting Corporation. The program is heard by a national audience in Canada of nearly 800,000 people, and by thousands more around the world on our weekly podcast.

For the past 40 years, Quirks & Quarks has brought its listeners to the cutting edge of scientific inquiry. Every week, the program presents the people behind the latest discoveries in the physical and natural sciences - from the smallest sub-atomic particle to the largest objects in the sky and everything in between. The program also examines the political, social, environmental and ethical implications of new developments in science and technology. Quirks & Quarks is a program for people fascinated by the world above, below and around them. And you don't need a PhD to enjoy it.

Join host Bob McDonald each week to find out the latest in science, technology, medicine and the environment. We cover every aspect of science, from the quirks of the expanding universe to the quarks within a single atom...and everything in between.

Over its lifetime, Quirks & Quarks has won more than 80 national and international awards for science journalism.
