U.S. researchers said on Tuesday they have made the darkest material on Earth, a substance so black it absorbs more than 99.9 percent of light. Made from tiny tubes of carbon standing on end, this material is almost 30 times darker than a carbon substance used by the U.S. National Institute of Standards and Technology as the current benchmark of blackness. And the material is close to the long-sought ideal black, which could absorb all colours of light and reflect none…

The substance has a total reflective index of 0.045 percent – which is more than three times darker than the nickel-phosphorous alloy that now holds the record as the world’s darkest material. Basic black paint, by comparison, has a reflective index of 5 percent to 10 percent. The researchers are seeking a world’s darkest material designation by Guinness World Records. But their work will likely yield more than just bragging rights. [Dr Pulickel] Ajayan said the material could be used in solar energy conversion. “You could think of a material that basically collects all the light that falls into it,” he said…

The researchers have tested the material on visible light only. Now they want to see how it fares against infrared and ultraviolet light, and other wavelengths such as radiation used in communications systems. “If you could make materials that would block these radiations, it could have serious applications for stealth and defence,” Ajayan said.

Further to this comment on the obligation to “mingle”, and via the Devil’s Kitchen, here’s Madsen Pirie on bright children as collective property. 

“It is wrong to allow bright children to go to special schools. This deprives the ordinary schools of their beneficial influence.”

If you regard children as the property of the state, existing to serve it, then it is explicable why the bright ones should be regarded as a scarce commodity, and rationed accordingly. The idea of allocating their “beneficial influence” equally through society follows from the same twisted logic. It is a pity that this is only applied to intelligence. Why should not the good-looking children be shared out equally, so their peer group has equal access to the pleasant sight of them? Perhaps the kind ones should be spread so that all may benefit equally from their sweet disposition?

The vicious notion is that children, whether bright or not, should be regarded as the instruments of the ends of others, instead of ends in themselves. Children do not exist to serve the purposes of the state; it is the other way round. The concern should be with what is of benefit to the individuals concerned, rather than with how they can be made to serve some ideological view of society. Behind the idea often lurks the doctrine of egalitarianism, and the feeling that children really ought not to be brighter than each other. With this comes the determination that nothing should be done to encourage it.
