Sir Ken Robinson put it in his excellent book Out of Our Minds: Learning to Be Creative, was subject to the division of labor: “Like an assembly line, students progressed from room to room to be taught by different teachers specializing in separate disciplines.

Stem Cell Exhaustion: As we age, our supply of stem cells plummets, in certain cases by a ten thousandfold decline. Worse, the ones we do manage to hang on to become far less active. This means that the body’s internal tissue and organ repair system loses its ability to do its job.

Studies have shown that games outperform textbooks in helping students learn fact-based subjects such as geography, history, physics, and anatomy, while also improving visual coordination, cognitive speed, and manual dexterity.

This last question may seem innocuous, but think about it this way: In 2006, retail was booming. Sears was worth $14.3 billion, Target $38.2 billion, and Walmart a whopping $158 billion. Meanwhile, an upstart retailer named Amazon was at $17.5 billion. Now fast-forward a decade. What’s changed? Hard times hit Main Street. By 2017, Sears had lost 94 percent of its value, ending the decade worth $0.9 billion, before promptly going out of business. Target did better, finishing up at $55 billion. Walmart did the best, going up to $243.9 billion. But Amazon? The Everything Store closed out the era worth $700 billion (today $800 billion). And it’s a fairly safe bet that your life changed as a result.

Electrical signals require electrons, which generate heat, which limits the amount of work a chip can perform and requires a lot of power for cooling. Light has neither limitation. If IBM’s estimations are correct, over the next eight years, its new chip design will accelerate supercomputer performance a thousandfold, taking us from our current 2.6 petaflops to an exaflop (that’s 10 to the 18th, or a quintillion operations per second) — or one hundred times faster than the human brain.

Once we start believing that the apocalypse is coming, the amygdala goes on high alert, filtering out most anything that says otherwise. Whatever information the amygdala doesn’t catch, our confirmation bias — which is now biased toward confirming our eminent destruction — certainly does. Taken in total, the result is a population convinced that the end is near and there’s not a damn thing to do about it.

In the developing world, where sanitation issues cause tremendous death and disease, this will obviously save millions and millions of lives, but in the developed world, three-quarters of our water bill is the cost of hauling away waste and running sewage treatment plants. So the goal is to solve both problems: to find a way for people to go to the bathroom that doesn’t involve running water or sewage, while still rendering human waste completely harmless.

5x5x5 Rapid Innovation Method, a very concrete way of putting Shiv’s notion into practice. “The idea is fairly simple and straightforward,” he says. “A company looking to drive breakthroughs in a particular area sets up five teams of five people and gives each team five days to come up with a portfolio of five ‘business experiments’ that should take no longer than five weeks to run and cost no more than five thousand dollars each to conduct.

we need to understand the way our brain shapes our beliefs and our beliefs shape our reality. There is perhaps no one better suited to help us look at this issue than the Nobel Prize–winning economist Daniel Kahneman.

Each of us has an internal “line of credibility.” When we hear of an idea that is introduced below this line, we dismiss it out of hand. If the teenager next door declares his intent to fly to Mars, you smirk and move on. We also have an internal line of supercredibility.

Yet climate migration is a peculiar kind of forced migration, as we ourselves are doing the forcing. The cost in both hard dollars and human suffering is much higher than we should be willing to pay. With a population of 38 million, Tokyo is the largest mega-city on Earth. Consider what it would cost to relocate fifteen Tokyos. Now consider that this is an entirely voluntary expense.

The London coffee-houses provided a gathering place where, for a penny admission charge, any man who was reasonably dressed could smoke his long, clay pipe, sip a dish of coffee, read the newsletters of the day, or enter into conversation with other patrons. At the period when journalism was in its infancy and the postal system was unorganized and irregular, the coffee-house provided a centre of communication for news and information … Naturally, this dissemination of news led to the dissemination of ideas, and the coffee-house served as a forum for their discussion.

National Science Foundation report on the subject pointed out, “nanotechnology has the potential to enhance human performance, to bring sustainable development for materials, water, energy, and food, to protect against unknown bacteria and viruses, and even to diminish the reasons for breaking the peace [by creating universal abundance].
