In How We Got to Now, the TV series based on the book of the same name, Steven Johnson explains how the wine press was used to print books, which resulted in a surge in demand for reading glasses, which had yet more unintended effects.
Johnson calls this cascade of inadvertent invention the Hummingbird Effect.
This is how change happens in the natural world: sometime during the Cretaceous age, flowers began to evolve colors and scents that signaled the presence of pollen to insects, who simultaneously evolved complex equipment to extract the pollen and, inadvertently, fertilize other flowers with pollen.
Over time, the flowers supplemented the pollen with even more energy-rich nectar to lure the insects into the rituals of pollination. Bees and other insects evolved the sensory tools to see and be drawn to flowers, just as the flowers evolved the properties that attract bees. The symbiosis between flowering plants and insects that led to the production of nectar ultimately created an opportunity for much larger organisms -- the hummingbirds -- to extract nectar from plants, though to do that they evolved a extremely unusual form of flight mechanics that enable them to hover alongside the flower in a way that few birds can even come close to doing. In other words, they had to learn an entirely new way to fly.
In an interview with Popular Mechanics, Johnson shared another example:
At the start of the 20th century, in Brooklyn, a printer was doing full-color magazines. In the summer the ink didn't set up properly. The printer hired a young engineer, Willis Carrier, to devise a way to bring down the temperature and humidity in the room. He built this contraption that made the printing possible. Then the workers were like, "I'm gonna have my lunch in the room with the contraption, it's cool in there." Carrier says, "Hmm, that's interesting." He sets up the Carrier Corporation, which air-conditions movie theaters, paving the way for the summer blockbuster. Before air conditioning, a crowded theater was the last place you wanted to go. After a/c, summer movies become part of the cultural landscape.
Speaking of PBS shows, Steven Johnson's How We Got to Now starts on PBS tonight with two back-to-back episodes. The NY Times has a positive review.
The opening episode, for instance, is called "Clean," and it sets the pattern for the five that follow. We tend not to acknowledge just how recent some of the trends and comforts of modern life are, including the luxury of not walking through horse manure and human waste on the way to the post office.
The episode turns back the clock just a century and a half, to a time before our liquid waste stream was largely contained in underground pipes. Mr. Johnson then traces the emergence of the idea that with a little effort, cities and towns could have a cleaner existence, and the concurrent idea that cleanliness would have public health benefits.
But his examination of "the ultraclean revolution," as he calls it, doesn't stop at the construction of sewage and water-purification systems. He extends the thread all the way to the computer revolution, visiting a laboratory where microchips are made.
The show is based on Johnson's book of the same name, which enters the NY Times bestseller list at #4 this week. Also, I keep wanting to call the book/show How We Got to Know, which strikes me as a perfectly appropriate title as well.
Update: The first two episodes are available online until 10/30.
Update: How We Got to Now is now available on Netflix and Amazon Prime Video.
Steven Johnson has been working on a six-part series for PBS called How We Got to Now. (There's a companion book as well.) The series is due in October but the trailer dropped today:
And here's a snippet of one of the episodes about railway time. I'm quite looking forward to this series; Johnson and I cover similar ground in our work with similar sensibilities. I'm always cribbing stuff from his writing and using his frameworks to think things through and just from the trailer, I counted at least three things I've covered on kottke.org in the past: Hedy Lamarr, urban sanitation, and Jacbo Riis (not to mention all sorts of stuff about time).
Now this looks interesting: Steven Johnson is doing a six-episode series on PBS about the 500-year histories of several aspects of modern life. Sounds right up my alley...and also quite Connections-ish.
The show builds on many of themes in the innovation history trilogy of The Ghost Map, The Invention Of Air, and Where Good Ideas Come From, but is based on new material with a completely different structure. Each hour-long episode takes one facet of modern life that we mostly take for granted -- artificial cold, clean drinking water, the lenses in your spectacles -- and tells the 500-year story of how that innovation came into being: the hobbyists and amateurs and entrepreneurs and collaborative networks that collectively made the modern world possible. It's also the story of the unintended consequences of these inventions: air conditioning and refrigeration didn't just make it possible to build ski slopes in the desert; they also triggered arguably the largest migration of human beings in the history of the species -- to cities like Dubai or Phoenix that would otherwise be virtually uninhabitable.
Outside of the nature documentaries like Planet Earth, I haven't seen a decent science series on TV in a long while -- most of them are too slow with too much filler and not enough actual, you know, science -- so I'm not getting my hopes up too high, but hoping this one bucks that trend.
