My radio documentary on Galileo and the history of the telescope, "Looking Up," airs this month on Ideas on CBC Radio One.

Part One -- Monday Oct. 12 at 9:05 p.m.
Part Two -- Monday Oct. 19 at 9:05 p.m.

As described on the Ideas website: "Four hundred years ago, a novel optical device from Holland made its way to Italy and into the hands of a free-thinking mathematician named Galileo Galilei. He soon aimed the instrument skyward - and our universe changed forever. Since that time, astronomers have been building bigger and better telescopes - and their discoveries continue to challenge us. Science journalist Dan Falk tells the remarkable story of Galileo and the revolution he began."

A short video of the “falling bodies” experiment can be viewed on YouTube.
