Steven Johnson is hosting a new six-part PBS series called How We Got To Now that will start on October 15th (he also wrote a companion book). Here’s how PBS describes it:

Johnson explains how the answers to the questions he poses in each episode — such as “how do we make something cold?” or “how do we create light?”— have driven other discoveries through the web of ideas and innovations that made each finding possible. Tracking each pursuit through history both ancient and contemporary, Johnson unlocks tales of unsung heroes and radical revolutions that changed the world and the way we live in it.

Here’s a trailer for the show, along with an interview Jon Stewart did with Johnson this past week. I’m adding this info to The Best Sites Where Students Can Learn About Inventions.
