Guest Post: Tom Levenson on Isaac Newton as the First Cosmologist | Cosmic Variance - 0 views

  • Newton knew what he had done. He was no accidental writer. A parabola, of course, is a curve that keeps on going – and that meant that at the end of a very long and very dense book, he lifted off again from the hard ground of daily reality and said, in effect, look: All this math and all these physical ideas govern everything we can see, out to and past the point where we can’t see anymore. Most important, he did so with implacable rigor, a demonstration that, he argued, should leave no room for dissent. He wrote “The theory that corresponds exactly to so nonuniform a motion through the greatest part of the heavens, and that observes the same laws as the theory of the planets and that agrees exactly with exact astronomical observations cannot fail to be true.” (Italics added).
  • To make his ambitions absolutely clear Newton used the same phrase for the title of book three. There his readers would discover “The System of the World.” This is where the literary structure of the work really comes into play, in my view. Through book three, Newton takes his audience through a carefully constructed tour of all the places within the grasp of his new physics. It begins with an analysis of the moons of Jupiter, demonstrating that inverse square relationships govern those motions. He went on, to show how the interaction between Jupiter and Saturn would pull each out of a perfect elliptical orbit; the real world, he says here, is messier than a geometer’s dream.

Hello, Darkness - 96.03 - 0 views

  • But the implication of electricity in the sleep deficit seems hard to argue with. Whatever it is that we wish or are made to do--pursue leisure, earn a living--there are simply far more usable hours now in which to do it
  • In the United States at midnight more than five million people are at work at full-time jobs. Supermarkets, gas stations, copy shops--many of these never close.
  • Living with electric lights makes it difficult to retrieve the experience of a non-electrified society. For all but the very wealthy, who could afford exorbitant arrays of expensive artificial lights, nightfall brought the works of daytime to a definitive end. Activities that need good light--where sharp tools are wielded or sharply defined boundaries maintained; purposeful activities designed to achieve specific goals; in short, that which we call work--all this subsided in the dim light of evening. Absent the press of work, people typically took themselves safely to home and were left with time in the evening for less urgent and more sensual matters: storytelling, sex, prayer, sleep, dreaming.

  • John Staudenmaier, a historian of technology and a Jesuit priest, for a recent conference at MIT. (The essay will appear in a book called The Idea of Progress Revisited, edited by Leo Marx and Bruce Mazlish.) Staudenmaier makes the point--obvious when brought up, though we've mostly lost sight of it--that from the time of the hominid Lucy, in Hadar, Ethiopia, to the time of Thomas Edison, in West Orange, New Jersey, the onset of darkness sharply curtailed most kinds of activity for most of our ancestors.

    Speculative connections between electric lighting, sleep deficits, and health.
  •  
    I wonder if the driving force behind the sleep deficit is in fact more pervasive, and indeed global in nature: the triumph of light.

The Technium: The Unabomber Was Right - 0 views

  • Besides lacking a desirable alternative, the final problem with destroying civilization as we know it is that the alternative, such as it has been imagined by the self-described “haters of civilization”, would not support but a fraction of the people alive today. In other words, the collapse of civilization would kill billions. Ironically the poorest rural inhabitants would fare the best, as they could retreat to hunting gathering with the least hurdle, but billions of urbanites would die once food ran out and disease took over. The anarcho-primitives are rather sanguine about this catastrophe, arguing that accelerating the collapse early might save lives in total.
  • The ultimate problem is that the paradise the Kaczynski is offering, the solution to civilization so to speak, is the tiny, smoky, dingy, smelly wooden prison cell that absolutely nobody else wants to dwell in. It is a paradise billions are fleeing from. Civilization has its problems but in almost every way it is better than the Unabomber’s shack. The Unabomber is right that technology is a holistic, self-perpetuating machine. He is wrong to bomb it for many reasons, not the least is that the machine of civilization offers us more actual freedoms than the alternative. There is a cost to run this machine, a cost we are only beginning to reckon with, but so far the gains from this ever enlarging technium outweigh the alternative of no machine at all.

PLoS ONE: A Demonstration of the Transition from Ready-to-Hand to Unready-to-Hand - 1 views

  • In Chapter III of Being and Time, Heidegger distinguishes three modes of experiencing the world. Most human activity, Heidegger argued, is absorbed, skillful engagement with entities in the world. When we are coping skillfully with the world, we experience entities around us as ready-to-hand.
  • Heidegger argues that skilled coping, when we engage with entities as ready-to-hand, is our primary way of engaging with the world. Sometimes, though, our skillful coping is temporarily disturbed. When this happens, we encounter entities as unready-to-hand. When we go from smoothly hammering to having difficulty, our experience of the previously ready-to-hand entities changes: we experience the hammer, nails and board as failing to serve their function appropriately.
  • Heidegger's third way of experiencing the world is as present-at-hand. The hammer is encountered as present-at-hand when we stop hammering and consider the hammer's shape or color or weight; when considered this way the hammer is no longer a useful tool but merely an object with various properties. Heidegger argued that readiness-to-hand is primary in two ways. First, the majority of our experience of the world is engaging with entities ready-to-hand. Second, readiness-to-hand is, from a phenomenological standpoint, ontologically primary while the other modes are derivative of it.

The Technium: The Most Powerful Force in the World - 0 views

  •  
    Even counting vast tracks of agriculture, the technium entails fewer than one percent of the atoms on the Earth's land surface. Yet the impact which this minute fraction of technological mass and energy has on the planet is in far disproportion to its size. Measured by impact per gram or calorie, there is nothing comparable to things we invent. Technology is the most powerful force in the world.

The Role of Intimacy in the Evolution of Technology - 0 views

  •  
    by Alessandro Tomasi In this article, Georges Bataille's notion of intimacy will be re-interpreted to show that it has a role to play in the evolution of technology. The specifically human form of intimacy can be experienced through the successful adoption of technological devices that have the qualities necessary to fit in and work out in our life context. If they manage to become part of our life, then we experience them as projections of our psychophysical personality, and, as such, they escape our positing, objectifying consciousness. Intimacy can be seen as the organizing principle that shapes the evolution of technology towards an ideal end that promises at least an approximation to the absolute intimacy that is unique to the gods.
