The Null Device


Industrial design of the day: this folding UK mains plug:

Not much is known about who designed it (the video is posted by a "MrMinKyuChoi", though the narrator of the video is female, with an accent), though it certainly is ingenious, and solves the problem of British mains plugs being huge and chunky (which may have been reassuring when attached to an electric kettle, but doesn't quite fit comfortably in a laptop sleeve, in the way that plugs in most of the rest of the world do.)

The narrator asserts that the plug fully meets Britain's exacting safety standards. If this is the case, and the wear and tear of folding and unfolding it doesn't cause it to explode in flames or electrocute the user, it is a neat piece of design.

(Britain's rather conservative specifications for plugs and sockets seem to have something to do with the fact that, in a fit of post-war thrift, British houses were wired for electricity using a single ring of copper cable, rather than a length for each socket (which would be safer and more expensive), which is the case with the rest of the world. I'm not an electrical engineer, though I wonder whether (a) adopting the European plug standards (you know, the slender round-pinned ones they use on the continent) would have been more hazardous with ring mains, or whether there was somewhat of an ideological nativism and/or imperial exceptionalism in Britain's decision to roll its own rather than surrender their wall outlets to Johnny Foreigner.)

Anyway, if this idea works and ends up being manufactured, I'd gladly buy a few.

The British Psychological Society's journal, The Psychologist, has a fascinating article about outbreaks of mass hysteria and "dancing plagues" in the Middle Ages:

The year was 1374. In dozens of medieval towns scattered along the valley of the River Rhine hundreds of people were seized by an agonising compulsion to dance. Scarcely pausing to rest or eat, they danced for hours or even days in succession. They were victims of one of the strangest afflictions in Western history. Within weeks the mania had engulfed large areas of north-eastern France and the Netherlands, and only after several months did the epidemic subside. In the following century there were only a few isolated outbreaks of compulsive dancing. Then it reappeared, explosively, in the city of Strasbourg in 1518. Chronicles indicate that it then consumed about 400 men, women and children, causing dozens of deaths (Waller, 2008).
Not long before the Strasbourg dancing epidemic, an equally strange compulsion had gripped a nunnery in the Spanish Netherlands. In 1491 several nuns were ‘possessed’ by devilish familiars which impelled them to race around like dogs, jump out of trees in imitation of birds or miaow and claw their way up tree trunks in the manner of cats. Such possession epidemics were by no means confined to nunneries, but nuns were disproportionately affected (Newman, 1998). Over the next 200 years, in nunneries everywhere from Rome to Paris, hundreds were plunged into states of frantic delirium during which they foamed, screamed and convulsed, sexually propositioned exorcists and priests, and confessed to having carnal relations with devils or Christ.
The article examines these phenomena, dismissing various theories (such as them being caused by ergotism, or the consumption of bread contaminated with hallucinogenic mould), and makes the case that they were culture-bound psychogenic illnesses, enabled by accepted beliefs about the supernatural and triggered by stress:
Similarly, it is only by taking cultural context seriously that we can explain the striking epidemiological facts that possession crises so often struck religious houses and that men were far less often the victims of mass diabolical possession. The daily lives of nuns were saturated in a mystical supernaturalism, their imaginations vivid with devils, demons, Satanic familiars and wrathful saints. They believed implicitly in the possibility of possession and so made themselves susceptible to it. Evangelical Mother Superiors often made them more vulnerable by encouraging trance and ecstasy; mind-altering forms of worship prepared them for later entering involuntary possession states. Moreover, early modern women were imbued with the idea that as the tainted heirs of Eve they were more liable to succumb to Satan, a misogynistic trope that often heightened their suggestibility.
Theological conventions also conditioned the behaviour of demoniac nuns. This is apparent from the fact that nearly all possession epidemics occurred within a single 300-year period, from around 1400 to the early 1700s. The reason is that only during this period did religious writers insist that such events were possible (Newman 1998). Theologians, inquisitors and exorcists established the rules of mass demonic possession to which dissociating nuns then unconsciously conformed: writhing, foaming, convulsing, dancing, laughing, speaking in tongues and making obscene gestures and propositions. These were shocking but entirely stereotypical performances based on deep-seated beliefs about Satan’s depravity drawn from religious writings and from accounts of previous possessions. For centuries, then, distress and pious fear worked in concert to produce epidemics of dancing and possession.
The article concludes with examples of modern occurrences of such phenomena, from the rather feeble examples (such as epidemics of fainting) one could find in a materialistic post-Enlightenment society to "spirit possession" among factory workers drawn from rural communities in Malaysia and Singapore, to delusions of penis-stealing witchcraft in western Africa.
