Looking Up On Ideas
400 years ago, a novel optical device from Holland made its way to Italy. There, it got 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.
This week on IDEAS, science journalist Dan Falk tells the remarkable story of Galileo and the revolution he began.
It's a part one of a special celebration of astronomy on IDEAS. Monday, October 12th at 9 p.m. (9:30 NT) on CBC Radio One. Part two airs on Monday, October 19th.
