English spelling, owing to the conditions that gov- ernd the growth of the English language, now presents many anomalies. The same letter, or combination of letters, often represents many different sounds; while the same sound is often represented by many different letters, or combinations of letters. The combination…
Colorado Mesa University was typical of most public institutions in the fall of 2007, with out-of-state students making up a small number, about 5 percent, of the overall student body. But when the economic downturn hit in the fall of 2008, and state support for higher education began dwindling, Colorado Mesa…
Back then, I thought of one thing: Have you heard of the Monte Carlo method? Ah, it’s a computer algorithm often used for calculating the area of irregular shapes. Specifically, the software puts the figure of interest in a figure of known area, such as a circle, and randomly strikes it with many tiny balls, never…
After waiting patiently for the noise to subside, one of the male Red Guards turned to the victim. “Ye Zhetai, you are an expert in mechanics. You should see how strong the great unified force you’re resisting is. To remain so stubborn will lead only to your death! Today, we will continue the agenda from the last…
This is a role-playing game. That means that you will be like an actor, imagining that you are someone else, and pretending to be that character. You won’t need a stage, though, and you won’t need costumes or scripts. You only need to imagine. This game doesn’t have a board, because you won’t need one. Besides, no…
The main difference between an instructional system and a selectional system is that the instructional system uses information from the environment to change the properties of the object in question, but a selectional system has a large and varied population of objects, and the ones that are most fit for the…
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…
But our unconscious feats of unweaving and weaving are greater even than this. Think what is happening when you listen to a whole orchestra. Imagine that, superimposed on a hundred instruments, your neighbour in the concert is whispering learned music criticism in your ear, others are coughing and, lamentably…
Moralists and theologians place great weight upon the moment of conception, seeing it as the instant at which the soul comes into existence. If, like me, you are unmoved by such talk, you still must regard a particular instant, nine months before your birth, as the most decisive event in your personal fortunes. It is…
Since I have had to pay college tuition for five daughters, I have chosen to play the role of preacher. I preach to all who will listen the gospel of manifest destiny. The destiny which I am preaching is not the expansion of a single nation or of a single species, but the spreading out of life in all its multifarious…
One may picture, then, these beings, nuclearly resident, so to speak, in a relatively small set of mental units, each utilizing the bare minimum of energy, connected together by a complex of etherial intercommunication, and spreading themselves over immense areas and periods of time by means of inert sense organs…
Piet Hut, another Dutch astronomer fifty years younger than Jan Oort, decided to take seriously the possibility that comet showers are periodic. If they are periodic, the theory that they are caused by the random passing-by of alien stars cannot be right. If showers are periodic, they must be explained by a different…
To understand why comet showers occur, we go back to the Oort Cloud. The theory of comet showers was worked out by Jack Hills, an American physicist now at Los Alamos. He realized that the movements of the comets in the Oort Cloud are not entirely random. Comets in the cloud are generally moving in random directions…
I cover my ears when Tawaddud shouts the Name. By now I have a fairly good idea about how it works. Extreme fractal compression of some kind, a self-referential loop inside a story, forcing the target brain to iterate it all over again, bootstrapping a new mind inside it into existence. How it is possible, I do not…
The designers of our species set out to produce a being that might be capable of an order of mentality higher than their own. The only possibility of doing so lay in planning a great increase in brain organisation. But they knew that the brain of an individual human being could not safely be allowed to exceed a…
There is a little local exomemory that opens up while Isidore studies the structure. It describes Eternitas as an ‘experiment in transforming exomemory data directly into architecture and livable spaces.’ The Oubliette is full of similar art projects – indeed, many of Isidore’s fellow students work on considerably…
For a while, one’s speaking is largely “fake” — that is, one is thinking in one’s native language but substituting words quickly enough to give the impression that the thinking is going on in the second language; however, as one’s experience with the second language grows, new grammatical habits form and turn slowly…
Certainly dystopia has appeared in science fiction from the genre’s inception, but the past decade has observed an unprecedented rise in its authorship. Once a literary niche within a niche, mankind is now destroyed with clockwork regularity by nuclear weapons, computers gone rogue, nanotechnology, and man-made…
As you successfully lock in Tetris puzzle pieces, you get three kinds of feedback: visual—you can see row after row of pieces disappearing with a satisfying poof; quantitative—a prominently displayed score constantly ticks upward; and qualitative—you experience a steady increase in how challenging the game feels. This…
Four circles to the kissing come, The smaller are the benter. The bend is just the inverse of The distance from the centre. Though their intrigue left Euclid dumb There's now no need for rule of thumb. Since zero bend's a dead straight line And concave bends have minus sign, The sum of squares of all four bends Is…
