I've written and presented more than a dozen feature-length radio documentaries, the majority prepared for the CBC Radio program Ideas. I've also written or produced a variety of shorter features for the CBC and other outlets. Some highlights:

The Value of Thought Experiments (The Philosopher's Zone, ABC Radio, Australia -- January 2018)

Science is rooted in "empiricism" -- the idea that the only way to learn about nature is via experiment and observation. But what if you could gain new knowledge just by thinking about a problem?

The Politics of the Professoriat (CBC Radio "Ideas" - Sept. 2017) 

Universities have long prided themselves in the free exchange of ideas. But according to social psychologist Jonathan Haidt, campuses now skew so far to the left that they've become "political monocultures." In this program, host Paul Kennedy speaks with Prof. Haidt and other scholars.

The Science of Morality (CBC Radio "Ideas" - October 2012)

The Idea of Genius (CBC Radio "Ideas" - 2011)
We live in awe of genius, of those few individuals capable of producing Hamlet, the Fifth Symphony, or the Theory of Relativity. Genius is more than talent, but what exactly is it? In this two-part series, science journalist Dan Falk explores our obsession with those who achieve greatness.

Living on Oxford Time (CBC Radio "Ideas" - 2008)
The guidebooks say that 'time stands still' among the dreaming spires of Oxford – and modern physics seems to agree. Journalist Dan Falk meets with three brilliant Oxford scientists – Roger Penrose, David Deutsch, and Julian Barbour – and searches for insight into a most peculiar dimension.

Einstein's Cosmos (CBC Radio "Ideas" - 2005)
In June of 1905, a German physics journal published Albert Einstein's first paper on relativity. A tour thorough Einstein's universe, with science journalist Dan Falk.

In the Beginning (CBC Radio "Ideas" - 2004)
Dan Falk winds back the clock to the birth of the cosmos 14 billion years ago, revealing strange worlds of dark energy and extra dimensions – perhaps even universes beyond our own. (Winner of a Gold Medal in Radio Programming from the New York Festivals.)

The Matter of Mind (CBC Radio "Ideas" - 2001)
No problem in science is more challenging that the puzzle of consciousness – how three pounds of grey matter gives rise to our experience of the world. A two-part Ideas documentary from science journalist Dan Falk.

The Question of Design (CBC Radio "Ideas" - 2000)
Our universe displays beauty, complexity, and order. For some, that indicates "design" – and, by extension, a designer; a proof, perhaps, for the existence of God. But science challenged that view, describing a universe that unfolds blindly by natural law. Yet design arguments continue to surface, from the anthropic principle in cosmology to the “intelligent design” movement in biology. Dan Falk weighs the evidence.

Einstein as Icon (CBC Radio "The Sunday Edition" - 2005)
Einstein was – and is – much more than just a towering scientific figure. Einstein made the great leap from scientific fame to cultural icon. In this documentary, first broadcast on CBC Radio's The Sunday Edition, science journalist Dan Falk looks at the forces that shaped Einstein's rise to fame, and kept him there for a hundred years. (Winner of the Science in Society Journalism Award from the Canadian Science Writers' Association.)
