In this game the floor is the sea. Half—rather the larger half because of some instinctive right of primogeniture—is assigned to the elder of my two sons (he is, as it were, its Olympian), and the other half goes to his brother. We distribute our boards about the sea in an archipelagic manner. We then dress our…
...innovation often occurs through sequencing—building on prior innovation. Recall that suitcases didn't used to have wheels. Then someone created a suitcase with two wheels. Now many suitcases have four wheels. What helpful improvement on the suitcase might come next? I've pitched this question to students, who then…
Before we discuss what current research tells us about memory and recall, it may be helpful to address a common misconception that emerged from the work ofCanadian neurosurgeon Wilder Penfield in the 1930s and 1940s. Penfield reported that during surgery, an electrical stimulation of the temporal lobe produced…
What if the 100,000-odd year-old evidence of human social life—from the arrowheads in South Africa, to the Venus figurines at Dordogne—is the effect of nothing, more or less, but our efforts to become parents? What if the 10,000-odd year-old record of civilization—from the tax accounts at temples in the Near East, to…
Whenever a Metroid player aquires a new power-up, her mind races back in time in a way not unlike what happens at a turning point in a movie. When a secret is revealed we are forced back through the story to mentally review everything we've seen so far, sometimes changing the interpretation of entire scenes. [...]…
The painter is standing a little back from his canvas [1]. He is glancing at his model; perhaps he is considering whether to add some finishing touch, though it is also possible that the first stroke has not yet been made. The arm holding the brush is bent to the left, towards the palette; it is motionless, for an…
For the last decade, the science of aging has increasingly focused on sirtuins, a group of genes that are believed to protect many organisms, including mammals, against diseases of aging. Mounting evidence has demonstrated that resveratrol, a compound found in the skin of grapes as well as in peanuts and berries…
Los Angeles is not really a city of skyscrapers. All around those skyscrapers is a flat expanse of one- and two-story buildings. This low-density urban development means you have to drive to get around in LA. Los Angeles’ sprawl is considered a classic case of failed urban planning.Los Angeles’ sprawl is considered a…
More than four decades later, in her last moments, Ye Wenjie would recall the influence Silent Spring had on her life. The book dealt only with a limited subject: the negative environmental effects of excessive pesticide use. But the perspective taken by the author shook Ye to the core. The use of pesticides had…
"The fall of Trantor," said Seldon, "cannot be stopped by any conceivable effort. It can be hastened easily, however. The tale of my interrupted trial will spread through the Galaxy. Frustration of my plans to lighten the disaster will convince people that the future holds no promise to them. Already they recall the…
It happened three times in the past that theoretical astronomers invented a new planet on the basis of indirect and circumstantial evidence. The first time was in 1845 when Adams and Leverrier independently deduced the existence of the planet Neptune from the perturbations which it had produced in the motion of…
Tally spent the day walking around the city, marveling at how different it was from her own. She saw new pretties and uglies hanging out together, friends that the operation hadn't separated. And littlies clinging to their ugly older brothers and sisters instead of being stuck in Crumblyville with their parents. Those…
he most common example used is the hives of social insects, where all individuals work for the common good with little regard for themselves. Although it has been argued that hives lack collective minds (Nicholls 1982) it should be noted that all such species communicate with chemical signals, and at least in the case…
"We uploaded via the router," Amber says, and looks confused for a moment. "There's a network on the other side of it. We were told it was FTL, instantaneous, but I'm not so sure now. I think it's something more complicated, like a lightspeed network, parts of which are threaded through wormholes that make it look FTL…
That's not a problem. The CO2 that's released by humans (and animals) is produced by metabolising carbon from food, and the food comes from plants that have been grown recently. During their growth, the plants have absorbed an equivalent amount of CO2 from the atmosphere. Even when eating meat, the animals are…
The way to solve the conflict between human values and technological needs is not to run away from technology, that's impossible. The way to resolve the conflict is to break down the barriers of dualistic thought that prevent a real understanding of what technology is—not an exploitation of nature, but a fusion of…
Ancient Taoist and Zen masters wrote about something called, "beginner's mind," or translated, the Japanese word shosin. In contemporary counseling the revolution taking place is finally catching onto their ancient message. Until around the 1990's a therapist was considered expert, authority, and guide until diverse…
Sagan had talked of the “great demotions.” Humanity had learned, painfully, that it did not live on a planet at the center of the universe, and further demotions followed. We were not (in Sagan’s view) the purpose of the Creation, not specially chosen by a divine authority, and were in fact just one evolutionary twist…
The circulation of accurate and meaningful natural science ideas is of vital concern to our age. These are abundant in science but scarce in society. They should be rendered accessible to all. . . without education in natural science it is impossible to develop a strong intellect.... By placing natural science at the…
For want of a nail the shoe was lost. For want of a shoe the horse was lost. For want of a horse the rider was lost. For want of a rider the battle was lost. For want of a battle the kingdom was lost. And all for the want of a horseshoe nail.
