A tin foil hat is a hat made from one or more sheets of aluminium foil, or a piece of conventional headgear lined with foil, often worn in the belief or hope that it shields the brain from threats such as electromagnetic fields, mind control, and mind reading. The notion of wearing homemade headgear for such protection has become a popular stereotype and byword for paranoia, persecutory delusions, and belief in pseudoscience and conspiracy theories.
Phonograph cylinders are the earliest commercial medium for recording and reproducing sound. Commonly known simply as "records" in their era of greatest popularity, these hollow cylindrical objects have an audio recording engraved on the outside surface, which can be reproduced when they are played on a mechanical cylinder phonograph. In the 1910s, the competing disc record system triumphed in the marketplace to become the dominant commercial audio medium.
Aluminium foil is aluminium prepared in thin metal leaves with a thickness less than 0.2 mm ; thinner gauges down to 6 micrometres are also commonly used. In the United States, foils are commonly measured in thousandths of an inch or mils. Standard household foil is typically 0.016 mm thick, and heavy duty household foil is typically 0.024 mm. The foil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful.
A radiant barrier is a type of building material that reflects thermal radiation and reduces heat transfer. Because thermal energy is also transferred by conduction and convection, in addition radiation, radiant barriers are often supplemented with thermal insulation that slows down heat transfer by conduction or convection.
Life Savers is an American brand of ring-shaped hard and soft candy. Its range of mints and fruit-flavored candies is known for its distinctive packaging, coming in paper-wrapped aluminum foil rolls.
Tin foil, also spelled tinfoil, is a thin foil made of tin. Tin foil was superseded after World War II by cheaper and more durable aluminium foil, which is still referred to as "tin foil" in many regions.
The "Experimental Talking Clock" was recorded c. 1878 by inventor Frank Lambert. It was long thought to be the world's oldest playable sound recording and is listed in both the Guinness Book of World Records and The Encyclopedia of Recorded Sound as such; however, an older phonautogram recording of Au clair de la lune from 1860 by Édouard-Léon Scott de Martinville was reproduced for the first time in 2008 with the aid of modern technology. The talking clock is still the oldest recording that can be played back with its own mechanism, without the involvement of digital technology.
A dictation machine is a sound recording device most commonly used to record speech for playback or to be typed into print. It includes digital voice recorders and tape recorder.
Tinfoil Hat Linux (THL) was a compact security-focused Linux distribution designed for high security developed by The Shmoo Group. The first version (1.000) was released in February 2002. By 2013, it had become a low-priority project. Its image files and source are available in gzip format. THL can be used on almost any modern PC, as it requires an Intel 80386 or better, with at least 8 MB of RAM. The distribution fits on a single HD floppy disk. The small footprint provides additional benefits beyond making the system easy to understand and verify- the computer need not even have a hard drive, making it easier to "sanitize" the computer after use.
