Tin foil hat

An Aluminum Hat, Aluhut or Stanniolhütchen is a headgear, which was made ​​of one or several layers of aluminum foil or similar material. The concept was first mentioned in 1927 published science fiction story "The Tissue -Culture King" by Julian Huxley, in which the protagonist discovers that " caps of metal foil " can be used to block the effects of telepathy. Although there are individual sightings, the term Aluhut or Aluminiumhutträger is mainly in English-speaking countries ( tinfoil has ) used metaphorically to denote supporters of conspiracy theories, generally paranoid or just very tiring people.

Use

Since Huxley's book the use of the term with paranoia and conspiracy theories is associated. That term can be applied to both other as needed too self-deprecating. The Journal of the American Bar Association reports from the trial of a civil rehabilitation, as an attempt " to Aluhut get rid of ." New York Times writer Tobin Harshaw summarizes the group of reasonably rational thinking people together than those who do not wear Aluhut.

Commentators of the Washington Post also use the term self-deprecating to express doubts about the world. Similar to the Aluhut immersed in the writings of Cato Institute, in which an author writes that he had hidden some documents just below his Aluhut.

The figure of speech need not to be set on people. Also, only single argument of a longer chain of reasoning are called " very Aluhut -like" than.

In allusion to the conspiracy theory connotations, but with actual physical background, the term is sometimes also used to illustrate the function of a metallic cover of RFID chips. These chips allow for example the non-contact reading data from smart cards and official identification documents like passports, are built into the RFID chips. A metal cover prevents reading.

Reception

The Linux distribution Tinfoil Hat Linux attached particular importance to safety. Later was added a WordPress plugin that also placed special emphasis on control and additional privacy settings includes while another WordPress plugin of the same name prevents the sending of private data.

The American journal of literature and politics, The Atlantic forgave temporarily an unofficial tinfoil has award for the strangest e- mail writer.

In the Futurama movie Into the Wild Green Yonder main character Fry wearing a Aluminum Hat, so as not to have to read the thoughts of his fellow man. In the computer game Toy Story 3 is one of the tasks is three people set up a Aluminum Hat.

The term is used as a name on the Internet. There is the blog The Tinfoil Hat, the Tinfoil Hat Sports Blog, the Tinfoil Hat Society as well as the blog Moms Tinfoil Hat, or to take advantage of the cloud offer TINFOILPHONE Android without a Google account.

Effects of a real Huts

WR Adey showed in the late 1970s that weak amplitude-modulated electromagnetic fields can stimulate the release of calcium ions from cells that are separated from the forebrain of chicken embryos. The author of the little -received article concludes that there is next to the thermal effect of further effects of electromagnetic fields on the brain. Despite some claims that the action of electromagnetic radiation has negative health consequences, could not connect between radio waves and reduced health demonstrated verifiable.

A well-constructed Aluminum Hat is similar to a Faraday Cage and therefore reduces the inside (usually harmless) radio waves. One common Schools in physics demonstration consists of an amplitude modulation radio on tin foil, which is then covered with a metal pail. This leads to a marked reduction in signal strength ( presumably because of the bucket and not because of the aluminum foil, the latter making useless ). The efficiency of such a cover in blocking such radiation will depend on the thickness of the aluminum foil. From half - millimeter - thick aluminum foil radiation above about 20 kHz ( eg, both medium wave and ultra short wave) is partially blocked. However, aluminum foil is not sold in this thickness, so that several layers are required by aluminum foil in order to achieve this effect.

The effectiveness of a Aluhuts as an electromagnetic shield to stop radio waves is greatly reduced by the fact that it is not a complete coverage. An AM radio under a metal bucket without a conductive layer underneath demonstrates the relative ineffectiveness of such an arrangement. In fact, due to the effect would a bottomless Faraday cage, which partly reflected incident radiation, a radio wave incident on the underside of the cap focused (eg, coming from under the carrier ), partly in the brain of the wearer.

While Aluhüte should have led to a better understanding of the effect of a Faraday cage, include investigations to use them to reduce radio waves, clear to pseudoscience. A study of students at MIT found that Aluhüte incident radiation can either increase or decrease depending on the frequency. The effect was observed to be independent of the relative positioning of the Aluhut carrier and the radiation source to one another.

The ability of aluminum foil to reflect infrared radiation, Israeli surgeons make being used to during surgical interventions to reduce use of a hood, the heat load on the head of the physician in preterm infants when their body's temperature regulation is not yet developed and therefore a require external heat source.
