At last weekend's privacy conference, Martha Nussbaum described in vivid terms the objectification of women by men acting anonymously on the internet.  This was not a simple argument that men look at porn and fantasize a level of control they will never achieve legally in the real world.  Instead she (and Brian Leiter and others) described the systematized targeting of individual woman in "cyber cesspools," complete with engineered images of rape and sodomy of the target, exhortations to molest and kill, revelation of personal addresses and social security numbers, and cybertrespasses designed to erase the target's web presence. This is not only control and objectification in fantasy (which is bad enough but usually not actionable), but control, objectification, and psychic rape in the real world. Most interestingly, Martha exposed much of the motivation of the wrongdoers as a species of ressentiment explored by Nietzche, an attempt by the powerless and resentful to wrest control from the strong whom they envy and fear.  It is no surprise that the worst abuses described at the conference were perpetrated against successful women who would be likely to prevail in an open contest of wits.  Only anonymous rumour can bring them down. Think of the arch-example of ressentiment:  James Claggart whose envy and distorted desire for Billy Budd leads to his whispered lies about Billy's involvement in mutiny. Consensus seemed to emerge that lega ...

It’s no problem for Harry Potter. Child’s play for Star Trek’s Starship Enterprise . But as fascinated as humanity has long been about the possibility of becoming invisible, reality has proven a difficult barrier to breach for would-be inventors. As it turns out, it is extraordinarily difficult to bend electromagnetic radiation — otherwise known as light — around objects or even people. Yet that’s exactly what must happen in order to produce the effect of Invisibility. If light could be made to flow around a body the way water does around a rock — instead of being reflected as usually happens — then that object, or person, could be rendered invisible. So much for the theory. In practice, though, all attempts so far to create a Cloak of Invisibility have come up against the fact that no naturally occurring materials bend light in this way. They all simply reflect. Enter meta-materials. These materials are artificial composites which possess exceptional properties due to their exotic structure. Tiny structures on their surface, smaller than the wavelength of the light striking them, can, if arranged correctly, cause light to be diverted. So far, most meta-material experiments have been conducted with microwave radiation — its longer wavelengths allow for correspondingly large structures on the material’s surface. The process is more difficult with visible light, which has much shorter wavelengths. But there is also a further, much more ...

Death, not wishing to betray any hint of his true intentions, begrudgingly took off his [[Cloak of Invisibility|Invisibility Cloak]] and gave it to Ignotus.

KentuckyFC writes "All Invisibility cloaks to date work by hiding an object embedded inside them. Now a group of physicists have worked out how to remotely Cloak objects that sit outside a cloaking material. The trick is to make the cloaking material with optical properties that are exactly complementary to the space outside them. Complementary means that the material reverses the effect the space has on a plane wave of light passing through it. To an observer this space would appear to vanish. The scientists say that to Cloak an object sitting outside the cloaking material, first measure its optical properties and then embed a "complementary image" of the object within the Cloak. So a plane wave is first distorted by the object but then restored to a plane by the complementary image of the object within the Cloak (abstract). An observer sees nothing. This method has another benefit. Objects hidden in conventional cloaks are blinded because no light enters the cloaked region. But objects that are remotely cloaked like this should still be able to see their surroundings." Read more of this story at Slashdot. ...
