🔗 Education 🔗 Organizations

The University of the Third Age is an international movement whose aims are the education and stimulation of mainly retired members of the community—those in their third 'age' of life. It is commonly referred to as U3A.

There is no universally accepted model for the U3A. Its original conception in France as an extramural university activity was significantly modified in the United Kingdom where it was recognized that most people of retirement age have something to contribute and the emphasis has been on sharing, without formal links to traditional universities.

Many English-speaking countries have followed this geragogic model, whereas continental European countries have mostly followed the French model. For historical reasons, Lifelong learning institutes is the term used in the United States for organizations that are similar to U3A groups.

A British U3A website reports this about "The Third Age" membership eligibility: "U3A membership is not related to a specific age but to a period in one’s life (the third age) after the second age of full-time employment and parental responsibility. Anybody in their third age can join U3A and this includes people who are working part-time. There is no lower age for membership."

Not to be confused with SuperDrive, a trademark used by Apple Computer for various disk drive products or the Super Disc, CD addon for the Super Nintendo Entertainment System.

The SuperDisk LS-120 is a high-speed, high-capacity alternative to the 90 mm (3.5 in), 1.44 MB floppy disk. The SuperDisk hardware was created by 3M's storage products group Imation in 1997, with manufacturing chiefly by Matsushita.

The SuperDisk had little success in North America; with Compaq, Gateway and Dell being three of only a few OEMs who supported it. It was more successful in Asia and Australia, where the second-generation SuperDisk LS-240 drive and disk was released. SuperDisk worldwide ceased manufacturing in 2003.

A Turing tarpit (or Turing tar-pit) is any programming language or computer interface that allows for flexibility in function but is difficult to learn and use because it offers little or no support for common tasks. The phrase was coined in 1982 by Alan Perlis in the Epigrams on Programming:

54. Beware of the Turing tar-pit in which everything is possible but nothing of interest is easy.

In any Turing complete language, it is possible to write any computer program, so in a very rigorous sense nearly all programming languages are equally capable. Showing that theoretical ability is not the same as usefulness in practice, Turing tarpits are characterized by having a simple abstract machine that requires the user to deal with many details in the solution of a problem. At the extreme opposite are interfaces that can perform very complex tasks with little human intervention but become obsolete if requirements change slightly.

Some esoteric programming languages, such as Brainfuck, are specifically referred to as "Turing tarpits" because they deliberately implement the minimum functionality necessary to be classified as Turing complete languages. Using such languages is a form of mathematical recreation: programmers can work out how to achieve basic programming constructs in an extremely difficult but mathematically Turing-equivalent language.

Puppy pregnancy syndrome (PPS) is a psychosomatic illness in humans brought on by mass hysteria.

The syndrome is thought to be localized in villages in several states of India, including West Bengal, Assam, Bihar, Jharkhand, Orissa, and Chhattisgarh, and has been reported by tens of thousands of individuals. It is far more prevalent in areas with little access to education.

People suffering from PPS believe that shortly after being bitten by a dog, puppies are conceived within their abdomen. This is said to be especially likely if the dog is sexually excited at the time of the attack. Victims are said to bark like dogs and have reported being able to see the puppies inside them when looking at water or hear them growling in their abdomen. It is believed that the victims will eventually die – especially men, who will give birth to their puppies through the penis.

Witch doctors offer oral cures, which they claim will dissolve the puppies, allowing them to pass through the digestive system and be excreted "without the knowledge of the patient".

Doctors in India have tried to educate the public about the dangers of believing in this condition. Most sufferers are referred to psychiatric services, but in some instances patients fail to take anti-rabies medication before symptom onset, thinking that they are pregnant with a puppy and that folk medicine will cure them. This misbelief is further compounded by witch doctors who state that their medicine will fail if sufferers seek standard treatment.

Some psychiatrists believe that PPS meets the criteria for a culture-bound disorder.

A Canticle for Leibowitz is a post-apocalyptic science fiction novel by American writer Walter M. Miller Jr., first published in 1959. Set in a Catholic monastery in the desert of the southwestern United States after a devastating nuclear war, the book spans thousands of years as civilization rebuilds itself. The monks of the Albertian Order of Leibowitz preserve the surviving remnants of man's scientific knowledge until the world is again ready for it.

The novel is a fixup of three short stories Miller published in The Magazine of Fantasy & Science Fiction that were inspired by the author's participation in the bombing of the monastery at the Battle of Monte Cassino during World War II. The book is considered one of the classics of science fiction and has never been out of print. Appealing to mainstream and genre critics and readers alike, it won the 1961 Hugo Award for best science fiction novel, and its themes of religion, recurrence, and church versus state have generated a significant body of scholarly research. A sequel, Saint Leibowitz and the Wild Horse Woman, was published posthumously in 1997.

The Manual (How to Have a Number One the Easy Way) is a 1988 book by "The Timelords" (Jimmy Cauty and Bill Drummond), better known as The KLF. It is a step-by-step guide to achieving a No.1 single with no money or musical skills, and a case study of the duo's UK novelty pop No. 1 "Doctorin' the Tardis".

Christmas Tree EXEC was the first widely disruptive computer worm, which paralyzed several international computer networks in December 1987. The malware ran on the IBM VM/CMS operating system.

Written by a student at the Clausthal University of Technology in the REXX scripting language, it drew a crude Christmas tree as text graphics, then sent itself to each entry in the target's email contacts file. In this way it spread onto the European Academic Research Network (EARN), BITNET, and IBM's worldwide VNET. On all of these systems it caused massive disruption.

The core mechanism of the ILOVEYOU worm of 2000 was essentially the same as Christmas Tree, although it ran on PCs rather than mainframes, was spread over a different network, and was scripted using VBScript rather than REXX.

SmartWater is a traceable liquid and forensic asset marking system (taggant) that is applied to items of value to identify thieves and deter theft. The liquid leaves a long lasting and unique identifier, whose presence is invisible except under an ultraviolet black light.

A milk watcher, milk saver, pot watcher, pot minder, milk guard, or boil over preventer is a cooking utensil placed at the bottom of a pot to prevent the foaming boil-over of liquids by collecting small bubbles of steam into one large bubble.
