Three maps should be provided, either in separate rooms or separated from each other by screens: one for each player, and one in the centre for the Umpire.* Each Commander and his subordinates will be allowed access only to their own map, the Umpire and his assistants moving from one side to the other. [...] Whenever…
To study the epidemiology of deaths involving firearms kept in the home, we reviewed all the gunshot deaths that occurred in King County, Washington (population 1,270,000), from 1978 through 1983. The medical examiner's case files were supplemented by police records or interviews with investigating officers or both…
At first sight, things seem quite similar in City Number Two. Again, there are ubiquitous cameras, perched on every vantage point. Only here we soon find a crucial difference. The devices do not report to the secret police. Rather, each and every citizen of this metropolis can lift his or her wristwatch/TV and call up…
You have to go through life with more than just passion for change; you need a strategy. I'll repeat that. I want you to have passion, but you have to have a strategy. Not just awareness, but action. Not just hashtags, but votes. [...] But to bring about structural change, lasting change, awareness is not enough. It…
Of course, it is a cliché of our times that we suffer from information overload because of the ubiquity of electronic media. And for fifty years, cognitive scientists have been harping on the limitations of the brain in processing information. Some have argued that Grice’s cooperative maxims are a way to manage the…
A generation ago 70 percent of children played outside; today the rate is down to 30 percent.209 In 2008 the nine-year-old son of the journalist Lenore Skenazy begged her to let him go home by himself on the New York subway. She agreed, and he made it home without incident. When she wrote about the vignette in a New…
In 1991 two hikers stumbled upon a corpse poking out of a melting glacier in the Tyrolean Alps. Thinking that it was the victim of a skiing accident, rescue workers jackhammered the body out of the ice, damaging his thigh and his backpack in the process. Only when an archaeologist spotted a Neolithic copper ax did…
Pretty soon, it will be possible to buy artificially brained robots that perform useful tasks around the house. If the price of such robots can be made affordable, then the demand for them will be huge. I believe in time that the world economy will be based upon brain-based computers. Such devices will be so useful…
PETWHAC stands for Population of Events That Would Have Appeared Coincidental. Population may seem an odd word, but it is the correct statistical term. I won't keep using capital letters because they stand so unattractively on the page. Somebody's watch stopping within ten seconds of the psychic's incantation…
Imagine a spaceship full of sleeping explorers, deep-frozen would-be colonists of some distant world. Perhaps the ship is on a forlorn mission to save the species before an unstoppable comet, like the one that killed the dinosaurs, hits the home planet. The voyagers go into the deep-freeze soberly reckoning the odds…
We look back through countless millions of years and see the great will to live struggling out of the intertidal slime, struggling from shape to shape and from power to power, crawling and then walking confidently upon the land, struggling generation after generation to master the air, creeping down into the darkness…
"I give them fifty milli-Helens," he said. This went totally missing on everyone. "A milli-Helen is enough beauty to launch exactly one ship," Zane explained, and the older Crims all laughed. "Fifty's pretty good."
Benoit Mandelbrot asked his famous question “How long is the coast of Britain?” long before this symposium was written, but it perfectly captures the sort of puzzle people in this crowd love. The question seems simple. Just look it up in the encyclopedia. But as Mandelbrot observed, the length of the coast of Britain…
The point of a good argument isn’t for one person to simply win over the other. It’s ideally for both to come away with cognitive gains. Even if the goal of an argument is to reach a decision, the goal isn’t to win, the goal is to define the parameters for a good decision and then make the best possible decision with…
Where power intervenes, transparency fails to provide accountability. This is the main fact that the residents of the Planetary Consortium and their ilk must grasp. Public-accessible cameras and citizen sousveillance of police is not enough. To truly hold the people at the top accountable, publicams should be placed…
The atoms like each other to different degrees. Oxygen, for instance in the air, would like to be next to carbon, and if they get near to each other, they snap together. If they’re not too close though, they repel and they go apart, so they don’t know that they could snap together. It’s just as if you had a ball, it…
When you look at the planet from low orbit, the impact of the Himalayas on Earth’s climate seems obvious. It creates the rain shadow to beat all rain shadows, standing athwart the latitude of the trade winds and squeezing all the rain out of them before they head southwest, thus supplying eight of the Earth’s…
Nobody is bom a specialist. Every child is born with comprehensive interests, asking the most comprehensively logical and relevant questions. Pointing to the logs burning in the fireplace, one child asked me, "What is fire?" I answered, "Fire is the Sun unwinding from the tree's log. The Earth revolves and the trees…
Don't be buffaloed by experts and elites. Experts often possess more data than judgment. Elites can become so inbred that they produce hemophiliacs who bleed to death as soon as they are nicked by the real world.
The bell ringing for church, we went thither immediately, and with hearts full of gratitude, returned sincere thanks to God for the mercies we had received: were I a Roman Catholic, perhaps I should on this occasion vow to build a chapel to some saint, but as I am not, if I were to vow at all, it should be to build a…
