 Shannon and Thorp Hack the Roulette Wheel

It was in this tinkerer’s laboratory that they set out to understand how roulette could be gamed, ordering “a regulation roulette wheel from Reno for $1,500,” a strobe light, and a clock whose hand revolved once per second. Thorp was given inside access to Shannon in all his tinkering glory: Gadgets . . . were everywhere. He had a mechanical coin tosser which could be set to flip the coin through a set number of revolutions, producing a head or tail according to the setting. As a joke...

 Microcosm of Imagination

Brooding, she changed the pool into the sea, and made the minnows into sharks and whales, and cast vast clouds over this tiny world by holding her hand against the sun, and so brought darkness and desolation, like God himself, to millions of ignorant and innocent creatures, and then took her hand away suddenly and let the sun stream down.

 Just-In-Time Learning

Teachers should create situations where the students are required to locate the facts and information specifically related to the context of the question at hand, and then to utilize that information effectively. An example is the Jasper Mathematics series created by the Vanderbilt University's Peabody College of Education. In these multimedia presentations, students are introduced to characters that are faced with a mathematical dilemma that the students help the characters solve. Rather tha...

 Oankali Crave Difference

Human beings fear difference,” Lilith had told him once. “Oankali crave difference. Humans persecute their different ones, yet they need them to give themselves definition and status. Oankali seek difference and collect it. They need it to keep themselves from stagnation and overspecialization. If you don’t understand this, you will. You’ll probably find both tendencies surfacing in your own behavior.” And she had put her hand on his hair. “When you feel a conflict, try to go the ...

 Rolling Triggers and Social Multipliers Explain the Flynn...

The most potent facet of our environment is other people. When something, perhaps the popularity basketball got from television, triggered greater participation in basketball, the average performance rose as individuals played more and got better. Initially, a few people learn to shoot with either hand, then others imitate them. The rise in average performance feeds back into a new challenge for each individual. Those who want to excel have to learn to pass with either hand and this spreads a...

 Standing Desks Improve Student Engagement

The research looked at the results of an experiment in which 282 participants in grades 2-4 were observed in the fall and spring during one school year. Student engagement was monitored by actions such as answering a question, raising a hand, or participating in discussion, while off-task behaviors included talking out of turn. Engagement of the "treatment" classrooms was compared with the engagement of "control" classrooms. The researchers noted that both groups showed "general increases in...

 Religion Prevented Immortality

The other way was if you do various kinds of mumbo-jumbo then this great agent in the sky will come down and give you eternal life, in which case you could have an infinite number of sports cars. And so Pascal’s wager: either you believe in God or you don’t; if there is no God it can’t do any harm to believe in him because he’s not going to punish you because he doesn’t exist; on the other hand if you don’t believe in him and there is one then he’ll be mad at you and you won’t...

 The Farmer Hypothesis

The farmer hypothesis, on the other hand, has the flavor of a horror story: Every morning on a turkey farm, the farmer comes to feed the turkeys. A scientist turkey, having observed this pattern to hold without change for almost a year, makes the following discovery: “Every morning at eleven, food arrives.” On the morning of Thanksgiving, the scientist announces this law to the other turkeys. But that morning at eleven, food doesn’t arrive; instead, the farmer comes and kills the entire...

 Prescriptivism and Descriptivism

So, you seem to be at an impasse. On the one hand, you have generations of grade school English teachers rightly warning their pupils that people might chuckle at them if they use the word ‘irregardless’. On the other hand, you have the scientific rigor of the modern linguistic community touting descriptivism as the torch-bearer of truth and enlightenment. Are you doomed to choose between a democracy of solecisms and a library of thousand-page tomes of writer’s regulations? Are things r...

 Robots and Nature

Our most powerful tool against the robots is the natural world. This fact is overlooked almost entirely in human/robot war literature because humans are the ones writing it, and humans tend to think of the natural world as basically a good thing to be in. Sure, we like our air conditioning, to be sheltered from the rain, and to avoid poisonous snakes, but in general we view the habitable zone of the Earth to be a pretty great thing to be in. This is no coincidence! Trillions of experiments co...
