...libraries are a natural example of a memory hierarchy when used in concert with our own desk space. In fact, libraries in themselves, with their various sections and storage facilities, are a great example of a memory hierarchy with multiple levels. As a consequence, they face all sorts of caching problems. They…
Of the 20,000 to 30,000 genes now thought to be in the human genome, most cells express only a very small part - which makes sense, a liver cell has little need for the DNA code that makes neurons. But as almost all cells carry around a full copy ('distribution') of the genome, a system is needed to #ifdef out stuff…
As someone who works in tech, I like the analogy of a DoS attack. The root of the issue is attention capitalism. Our attention is essentially a resource being exploited for profit. In that scenario, we're effectivley no longer in control of our own free will as long as someone else can profit by controlling it. On an…
Consider for a moment just how many times Star Trek: The Motion Picture lingers upon the important act of a man entering -- or connecting to -- a machine. We watch Kirk's shuttle pod "dock" with Enterprise after a long, lingering examination of the ship. We see Spock, in a thruster suit, "penetrate" -- in his words…
Metaphor in science, Boyd suggests, is a version of the everyday process in which a metaphor is pressed into service to fill gaps in a language’s vocabulary, like rabbit ears to refer to the antennas that used to sprout from the tops of television sets. Scientists constantly discover new entities that lack an English…
If a teacher is a gardener, than a student is the seed. The classroom serves as the greenhouse creating a warm, safe environment for growth. An administrator is the soil, serving as a strong nutrient base for the seed to root. The parents are the water, providing live and maintaining it. When the water/parent is not…
Look at them, the bugs. Humans have used everything in their power to extinguish them: every kind of poison, aerial sprays, introducing and cultivating their natural predators, searching for and destroying their eggs, using genetic modification to sterilize them, burning with fire, drowning with water. Every family…
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…
...like curriculum, the garden is primarily a social construct that reflects the intent of the maker and the prevailing cultural ideologies of the time. The lived experiences of the person within both curriculum and garden are a synthesis of orchestrated and phenomenological experiences. The garden and the curriculum…
‘I talked to a woman of the Kaminari once,’ he says, ‘before the Spike. Don’t give me such a look, it wasn’t like that, we were just friends. But one night on Ganymede, we got philosophical. The Universe is a game, she said. It makes us into players. We can’t see the moves that are not allowed. Like in chess. There is…
My own field of physics is passing today through a phase of exuberant freedom, a phase of passionate prodigality. Sometimes as I listen to the conversation of my young colleagues at Princeton, I feel as if I am lost in a rain forest, with insects and birds and flowers growing all around me in intricate profusion…
"Crazy?" He rounded on her, all angles and motion, and shook a finger under her nose. "I know your type and your pathetic delusions. Oh, yes, I do. You think of a library as being like the mind of a great and noble Scholar—catholic, universally educated, and precisely organized. Every opinion balanced against its…
The distinctive characteristic of the Analytical Engine, and that which has rendered it possible to endow mechanism with such extensive faculties as bid fair to make this engine the executive right-hand of abstract algebra, is the introduction into it of the principle which Jacquard devised for regulating, by means of…
The only justification for our concepts is that they serve to represent thc complex of our experiences; beyond this they have no legitimacy. I am convinced that the philosophers had a harmful effect upon the progress of scientific thinking in removing certain fundamental concepts from the domain of empiricism, where…
Sure there is music even in the beauty, and the silent note which Cupid Strikes, far sweeter than the sound of an instrument. For there is music wherever there is harmony, order and proportion; and thus far we may maintain the music of the spheres; for those well ordered motions, and regular paces, though they give no…
"In your language you have a form of poetry called the sonnet…It is a very strict form of poetry, is it not? …There are fourteen lines, I believe, all in iambic pentameter. That’s a very strict rhythm, or meter…And each line has to end with a rigid rhyme pattern. And if the poet does not do it exactly this way, it is…
There are many similarities between genes and memes. Just as genes transmitted during sexual intercourse in the biosphere, so are ideas trans¬ mitted during social intercourse in the mental realm, or ideosphere. [...] The memetic realm also hahas some important differences from the genetic realm. Memes combine…
We must take our sensory experiences seriously but not literally. This is one place where the concept of a sensory desktop is helpful. We take the icons on a graphical desktop seriously; we won’t, for instance, carelessly drag an icon to the trash, for fear of losing a valuable file. But we don’t take the colors…
OK, I'm still in "Poetics," in Aristotle, and I'm thinking -- out of nowhere, two terms come crashing into my head that I haven't heard since my classics professor in college drilled them there. And they are anagnorisis and peripeteia. Anagnorisis and peripeteia. Anagnorisis is the Greek word for discovery. Literally…
The selfish gene theory is Darwin's theory, expressed in a way that Darwin did not choose but whose aptness, I should like to think, he would instantly have recognized and delighted in. It is in fact a logical outgrowth of orthodox neo-Darwinism, but expressed as a novel image. Rather than focus on the individual…
