HOW WE GOT TO NOW WITH STEVEN JOHNSON
Clean and Time

Air date: Wed., Oct. 15, 9:00 pm

 

Join best-selling author Steven Johnson to hear extraordinary stories behind remarkable ideas that made modern life possible, the unsung heroes who brought them about and the unexpected and bizarre consequences each of these innovations triggered.

 

Clean
Dirty water has killed more humans than all the wars of history combined, but in the last 150 years, a series of radical ideas, extraordinary innovations and unsung heroes have changed our world. Johnson plunges into a sewer to understand what made a maverick engineer decide to lift the city of Chicago with screw jacks in order to build America’s first sewer system. He talks about John Leal, who deliberately “poisoned” the water supply of 200,000 people when, without authorization, he added chlorine, considered lethal in 1908, into Jersey City’s water and made it safe to drink. This isn’t only about the world becoming a cleaner place — the iPhone, the subway, flat screen TVs and even the bikini are the result of the valiant efforts of the unsung heroes of clean.

 

Time
The world today is obsessed by time. Steven Johnson boards a submarine to discover what a lack of natural light means for a sailor’s working day and visits Heathrow, the world’s busiest airport, to try to get timings right at air traffic control. The story of getting a grip on time is full of curious garage tinkerers. One of them, railway clerk William F. Allen, was so exasperated by the chaos caused by the 8,000 local times zones in the U.S. that he fought tirelessly to standardize time into four zones. Learn how advancements in navigation, the way we work, technology and travel would have been impossible without the unsung heroes of time.
