Asimov Story on Computation

■ N 1958, American science fiction legend Isaac Asimov wrote a very short story called "The Feeling of Power." In it, lowly technician MyI ron Aub discovers that he is capable of duplicating the work of his computer by multiplying two numbers together on a piece of paper. Amazing! This miraculous discovery makes its way up the chain of command, where the generals and politicians are stunned by Aub's black magic. The top general is intrigued by the possibility that human calculations could g...

 Space is Negative Energy

The great mystery at the heart of the Big Bang is to explain how an entire, fantastically enormous universe of space and energy can materiahse out of nothing. The secret lies in one of the strangest facts about our cosmos. The laws of physics demand the existence of something called "negative energy." To help you get your head around this weird'd but crucial concept, let me draw on a simple analogy Imagine a man wants to build a hill on a flat piece of land. The hill will represent the univ...

 Competitive and Addictive Gaming VS Gaming for Play

The compulsive games-player, of course, is another universal phenomenon, particularly where gambling is a part of the game. The compulsive gambler is not made in a day: he descends an increasingly slippery path, eventually falling into a psychological trap from which escape is rare. The Chinese god of gambhng, Tu Chieng Kui, represents a man who spent his hfe gambling until he died, deeply in debt. Traditionally, statuettes made of him - known as 'a devil gambhng for cash' - show a figure in ...

 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...

 The Boundaries of a Game Versus Boundaries of Other Kinds...

What does it mean to say that games take place within set boundaries established by the act of play? Is this really true? Is there really such a distinct boundary? In fact there is. Compare, for example, the informal play of a toy with the more formal play of a game. A child approaching a doll, for example, can slowly and gradually enter into a play relationship with the doll. The child might look at the doll from across the room and shoot it a playful glance. Later, the child might pick it u...

 The Case Against Reading Too Broadly

The real problem with telling young writers to fan out across genres and forms is that it doesn’t help them find a voice. If anything, it’s antivoice. Learning the craft of writing isn’t about hopping texts like hyperlinks. It’s about devotion and obsession. It’s about lingering too long in some beloved book’s language, about steeping yourself in someone else’s style until your consciousness changes colour. It’s Tolkien phases and Plath crushes. It’s going embarrassingly, un...

 Lego Letter About Gender

To Parents The urge to create is equally strong in all children. Boys and girls. It’s the imagination that counts. Not skill. You build whatever comes into your head, the way you want it. A bed or a truck. A dolls house or a spaceship. A lot of boys like dolls houses. They’re more human than spaceships. A lot of girls prefer spaceships. They’re more exciting than dolls houses. The most important thing is to put the right material in their hands and let them create whatever appeals t...

 The Absurd Visions from a Post-Hypnotic Suggestion

I hardly heard him for trying to keep track of what was going on in my skull. I knew it was just post-hypnotic suggestion, even remembered the session in Missouri when they'd implanted it, but that didn't make it any less compelling. My mind reeled under the strong pseudo-memories: shaggy hulks that were Taurans (not at all what we now knew they looked like) boarding a colonists' vessel, eating babies while mothers watched in screaming terror (the colonists never took babies; they wouldn't st...

 Transcription Fluency

When you write something down, either while taking notes or while trying to write your own original thoughts, you’re dealing with what literacy scholars call “transcription fluency”: How quickly and fluidly you can get down — “transcribe” — the stuff that’s in your head. One of the reasons we formally teach handwriting to young children is that you don’t want a bottleneck between the ideas they’re forming and the writing. If you struggle with the act of forming let...

 How to Explain Science

As nearly as I can see, the only secret in popularising science (or anything else) is remembering what thinking went on in your head when you first really understood whatever it is you're now explaining: especially (1) what misunderstandings needed to be cleared away, (2) what metaphors and analogies proved helpful, and (3) what reassurance had to be offered. The effort involved is slight, the benefits great. Among the potential pitfalls are oversimplification, the need to be sparing w...
