Tarrare (c. 1772 – 1798), sometimes spelled Tarare, was a French showman and soldier, noted for his unusual eating habits. Able to eat vast amounts of meat, he was constantly hungry; his parents could not provide for him, and he was turned out of the family home as a teenager. He travelled France in the company of a band of thieves and prostitutes, before becoming the warm-up act to a travelling charlatan; he would swallow corks, stones, live animals and a whole basketful of apples. He then took this act to Paris where he worked as a street performer.

At the start of the War of the First Coalition, Tarrare joined the French Revolutionary Army. With military rations, though quadrupled, unable to satisfy his large appetite, he would eat any available food from gutters and refuse heaps but his condition still deteriorated through hunger. He was hospitalised due to exhaustion and became the subject of a series of medical experiments to test his eating capacity, in which, among other things, he ate a meal intended for 15 people in a single sitting, ate live cats, snakes, lizards and puppies, and swallowed eels whole without chewing. Despite his unusual diet, he was of normal size and appearance, and showed no signs of mental illness other than what was described as an apathetic temperament.

General Alexandre de Beauharnais decided to put Tarrare's abilities to military use, and he was employed as a courier by the French army, with the intention that he would swallow documents, pass through enemy lines, and recover them from his stool once safely at his destination. Tarrare could not speak German, and on his first mission was captured by Prussian forces, severely beaten and underwent a mock execution before being returned to French lines.

Chastened by this experience, he agreed to submit to any procedure that would cure his appetite, and was treated with laudanum, tobacco pills, wine vinegar and soft-boiled eggs. The procedures failed, and doctors could not keep him on a controlled diet; he would sneak out of the hospital to scavenge for offal in gutters, rubbish heaps and outside butchers' shops, and attempted to drink the blood of other patients in the hospital and to eat the corpses in the hospital morgue. After being suspected of eating a toddler he was ejected from the hospital. He reappeared four years later in Versailles with a case of severe tuberculosis, and died shortly afterwards, following a lengthy bout of exudative diarrhoea.

🔗 Video games

4X is a genre of strategy-based video and board games in which players control an empire and "eXplore, eXpand, eXploit, and eXterminate". The term was coined by Alan Emrich in his September 1993 preview of Master of Orion for Computer Gaming World. Since then, others have adopted the term to describe games of similar scope and design.

4X computer games are noted for their deep, complex gameplay. Emphasis is placed upon economic and technological development, as well as a range of non-military routes to supremacy. Games can take a long time to complete since the amount of micromanagement needed to sustain an empire increases as the empire grows. 4X games are sometimes criticized for becoming tedious for these reasons, and several games have attempted to address these concerns by limiting micromanagement, with varying degrees of success.

The earliest 4X games borrowed ideas from board games and 1970s text-based computer games. The first 4X computer games were turn-based, but real-time 4X games are not uncommon. Many 4X computer games were published in the mid-1990s, but were later outsold by other types of strategy games. Sid Meier's Civilization is an important example from this formative era, and popularized the level of detail that later became a staple of the genre. In the new millennium, several 4X releases have become critically and commercially successful.

In the board (and card) game domain, 4X is less of a distinct genre, in part because of the practical constraints of components and playing time. The Civilization board game that gave rise to Sid Meier's Civilization computer game, for instance, has no exploration and no extermination. Unless extermination is targeted at non-player entities, it tends to be either nearly impossible (because of play balance mechanisms, since player elimination is usually considered an undesirable feature) or certainly unachievable (because victory conditions are triggered before extermination can be completed) in board games.

A bastion fort or trace italienne (a phrase improperly derived from French, literally meaning Italian outline), is a fortification in a style that evolved during the early modern period of gunpowder when the cannon came to dominate the battlefield. It was first seen in the mid-15th century in Italy. Some types, especially when combined with ravelins and other outworks, resembled the related star fort of the same era.

The design of the fort is normally a polygon with bastions at the corners of the walls. These outcroppings eliminated protected blind spots, called "dead zones", and allowed fire along the curtain from positions protected from direct fire. Many bastion forts also feature cavaliers, which are raised secondary structures based entirely inside the primary structure.

The Scramble for Africa, also called the Partition of Africa or the Conquest of Africa, was the invasion, occupation, division, and colonisation of African territory by European powers during a short period known to historians as the New Imperialism (between 1881 and 1914). In 1870, only 10 percent of Africa was under formal European control; by 1914 this had increased to almost 90 percent of the continent, with only Ethiopia (Abyssinia), the Dervish state (a portion of present-day Somalia) and Liberia still being independent. There were multiple motivations for European colonizers, including desire for valuable resources available throughout the continent, the quest for national prestige, tensions between pairs of European powers, religious missionary zeal and internal African native politics.

The Berlin Conference of 1884, which regulated European colonisation and trade in Africa, is usually referred to as the ultimate point of the Scramble for Africa. Consequent to the political and economic rivalries among the European empires in the last quarter of the 19th century, the partitioning, or splitting up of Africa was how the Europeans avoided warring amongst themselves over Africa. The later years of the 19th century saw the transition from "informal imperialism" by military influence and economic dominance, to direct rule, bringing about colonial imperialism.

🔗 Psychology 🔗 Education

Bloom's taxonomy is a set of three hierarchical models used to classify educational learning objectives into levels of complexity and specificity. The three lists cover the learning objectives in cognitive, affective and sensory domains. The cognitive domain list has been the primary focus of most traditional education and is frequently used to structure curriculum learning objectives, assessments and activities.

The models were named after Benjamin Bloom, who chaired the committee of educators that devised the taxonomy. He also edited the first volume of the standard text, Taxonomy of Educational Objectives: The Classification of Educational Goals.

🔗 Computing 🔗 Computing/Software 🔗 Computing/Computer science

The fundamental theorem of software engineering (FTSE) is a term originated by Andrew Koenig to describe a remark by Butler Lampson attributed to the late David J. Wheeler:

"We can solve any problem by introducing an extra level of indirection."

The theorem does not describe an actual theorem that can be proven; rather, it is a general principle for managing complexity through abstraction.

The theorem is often expanded by the humorous clause "…except for the problem of too many levels of indirection," referring to the fact that too many abstractions may create intrinsic complexity issues of their own. For example, the use of protocol layering in computer networks, which today is ubiquitous, has been criticized in ways that are typical of more general disadvantages of abstraction. Here, the adding of extra levels of indirection may cause higher layers to duplicate the functionality of lower layers, leading to inefficiency, and functionality at one layer may need data present only at another layer, which fundamentally violates the goal of separation into different layers.

🔗 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."

🔗 Genetics 🔗 Evolutionary biology

Spiegelman's Monster is the name given to an RNA chain of only 218 nucleotides that is able to be reproduced by the RNA replication enzyme RNA-dependent RNA polymerase, also called RNA replicase. It is named after its creator, Sol Spiegelman, of the University of Illinois at Urbana-Champaign who first described it in 1965.

🔗 Mathematics

In number theory, the Green–Tao theorem, proved by Ben Green and Terence Tao in 2004, states that the sequence of prime numbers contains arbitrarily long arithmetic progressions. In other words, for every natural number k, there exist arithmetic progressions of primes with k terms. The proof is an extension of Szemerédi's theorem. The problem can be traced back to investigations of Lagrange and Waring from around 1770.

🔗 Game theory

The pirate game is a simple mathematical game. It is a multi-player version of the ultimatum game.
