🔗 Chemistry

Dry water , an unusual form of "powdered liquid", is a water–air emulsion in which tiny water droplets, each the size of a grain of sand, are surrounded by a sandy silica coating. Dry water actually consists of 95% liquid water, but the silica coating prevents the water droplets from combining and turning back into a bulk liquid. The result is a white powder that looks very similar to table salt. It is also more commonly known among researchers as empty water.

🔗 Cognitive science

Soar is a cognitive architecture, originally created by John Laird, Allen Newell, and Paul Rosenbloom at Carnegie Mellon University. (Rosenbloom continued to serve as co-principal investigator after moving to Stanford University, then to the University of Southern California's Information Sciences Institute.) It is now maintained and developed by John Laird's research group at the University of Michigan.

The goal of the Soar project is to develop the fixed computational building blocks necessary for general intelligent agents – agents that can perform a wide range of tasks and encode, use, and learn all types of knowledge to realize the full range of cognitive capabilities found in humans, such as decision making, problem solving, planning, and natural language understanding. It is both a theory of what cognition is and a computational implementation of that theory. Since its beginnings in 1983 as John Laird’s thesis, it has been widely used by AI researchers to create intelligent agents and cognitive models of different aspects of human behavior. The most current and comprehensive description of Soar is the 2012 book, The Soar Cognitive Architecture.

The Lives of Others (German: Das Leben der Anderen, pronounced [das ˈleːbm̩ deːɐ̯ ˈʔandəʁən] ) is a 2006 German drama film written and directed by Florian Henckel von Donnersmarck marking his feature film directorial debut. The plot is about the monitoring of East Berlin residents by agents of the Stasi, East Germany's secret police. It stars Ulrich Mühe as Stasi Captain Gerd Wiesler, Ulrich Tukur as his superior Anton Grubitz, Sebastian Koch as the playwright Georg Dreyman, and Martina Gedeck as Dreyman's lover, a prominent actress named Christa-Maria Sieland.

The film was released by Buena Vista International in Germany on 23 March 2006. At the same time, the screenplay was published by Suhrkamp Verlag. The Lives of Others won the Academy Award for Best International Feature Film. The film had earlier won seven Deutscher Filmpreis awards—including those for best film, best director, best screenplay, best actor, and best supporting actor—after setting a new record with 11 nominations. It also won the BAFTA Award for Best Film Not in the English Language and European Film Award for Best Film, while it was nominated for the Golden Globe Award for Best Foreign Language Film. The Lives of Others cost US$2 million and grossed more than US$77 million worldwide.

Released 17 years after the fall of the Berlin Wall, marking the end of the German Democratic Republic, it was the first notable drama film about the subject after a series of comedies such as Good Bye, Lenin! and Sonnenallee. This approach was widely applauded in Germany, and the film was complimented for its accurate tone despite some criticism that Wiesler's character was depicted unrealistically and with undue sympathy. The film's authenticity was considered praiseworthy given that the director grew up outside of East Germany and was 16 when the Berlin Wall fell.

Leachim was an early example of Diphone synthetic speech and demonstrated how voice branching could be done quickly via computer discs to create understandable speech (i.e. verbal output). This method combined phonemes, words, and sentences to form verbal responsive messages when prompted by the computer. The device received attention on a world-wide basis because hundreds of articles were written about it.

Old Tjikko is a 9,550 year-old Norway Spruce, located on Fulufjället Mountain of Dalarna province in Sweden. Old Tjikko originally gained fame as the "world's oldest tree." Old Tjikko is, however, a clonal tree that has regenerated new trunks, branches and roots over millennia rather than an individual tree of great age. Old Tjikko is recognized as the oldest living Picea abies and the third oldest known clonal tree.

The age of the tree was determined by carbon dating of genetically matched plant material collected from under the tree, as dendrochronology would cause damage. The trunk itself is estimated to be only a few hundred years old, but the plant has survived for much longer due to a process known as layering (when a branch comes in contact with the ground, it sprouts a new root), or vegetative cloning (when the trunk dies but the root system is still alive, it may sprout a new trunk).

Geneva Freeport (French: Ports Francs et Entrepôts de Genève SA) is a warehouse complex in Geneva, Switzerland, for the storage of art and other valuables and collectibles. The free port has been described as the "premier place" to store valuable works of art, and users "come for the security and stay for the tax treatment."

It is the oldest and largest freeport facility, and the one with the most artworks, with an estimated art collection value of US$100 billion. According to Jean-René Saillard of the British Fine Art Fund, "It would be probably the best museum in the world if it was a museum."

The Jesuit reductions were a type of settlement for indigenous people specifically in the Rio Grande do Sul area of Brazil, Paraguay and neighbouring Argentina in South America, established by the Jesuit Order early in the 17th century and wound up in the 18th century with the banning of the Jesuit order in several European countries. Subsequently, it has been called an experiment in "socialist theocracy" or a rare example of "benign colonialism".

In their newly acquired South American dominions, the Spanish and Portuguese Empires had adopted a strategy of gathering native populations into communities called "Indian reductions" (Spanish: reducciones de indios) and Portuguese: redução (plural reduções). The objectives of the reductions were to impart Christianity and European culture. Secular as well as religious authorities created "reductions".

The Jesuit reductions were Christian missions that extended successfully in an area straddling the borders of present-day Paraguay, Brazil, and Argentina (the triple frontera) amongst the Guaraní peoples. The reductions are often called collectively the Río de la Plata missions. The Jesuits attempted to create a "state within a state" in which the native peoples in the reductions, guided by the Jesuits, would remain autonomous and isolated from Spanish colonists and Spanish rule. A major factor attracting the natives to the reductions was the protection they afforded from enslavement and the forced labour of encomiendas.

Under the leadership of both the Jesuits and native caciques, the reductions achieved a high degree of autonomy within the Spanish colonial empire. With the use of native labour, the reductions became economically successful. When the incursions of Brazilian Bandeirante slave-traders threatened the existence of the reductions, Indian militias were set up, which fought effectively against the Portuguese colonists. However, directly as a result of the Suppression of the Society of Jesus in several European countries, including Spain, in 1767, the Jesuits were expelled from the Guaraní missions (and the Americas) by order of the Spanish king, Charles III. So ended the era of the Paraguayan reductions. The reasons for the expulsion related more to politics in Europe than the activities of the Jesuit missions themselves.

The Jesuit Rio de la Plata reductions reached a maximum population of 141,182 in 1732 in 30 missions in Brazil, Paraguay, and Argentina. The reductions of the Jesuit Missions of Chiquitos in eastern Bolivia reached a maximum population of 25,000 in 1766. Jesuit reductions in the Llanos de Moxos, also in Bolivia, reached a population of about 30,000 in 1720. In Chiquitos, the first reduction was founded in 1691 and in the Llanos de Moxos in 1682.

The Jesuit reductions have been lavishly praised as a "socialist utopia" and a "Christian communistic republic" as well as criticized for their "rigid, severe and meticulous regimentation" of the lives of the Indian people they ruled with a firm hand through Guaraní intermediaries.

Trout tickling is the art of rubbing the underbelly of a trout with fingers. If done properly, the trout will go into a trance after a minute or so, and can then easily be thrown onto the nearest bit of dry land.

🔗 Germany 🔗 Motorcycling

The Daimler Petroleum Reitwagen ("riding car") or Einspur ("single track") was a motor vehicle made by Gottlieb Daimler and Wilhelm Maybach in 1885. It is widely recognized as the first motorcycle. Daimler is often called "the father of the motorcycle" for this invention. Even when the three steam powered two wheelers that preceded the Reitwagen, the Michaux-Perreaux and Roper of 1867–1869, and the 1884 Copeland, are considered motorcycles, it remains nonetheless the first petrol internal combustion motorcycle, and the forerunner of all vehicles, land, sea and air, that use its overwhelmingly popular engine type.

🔗 Computer science

The man or boy test was proposed by computer scientist Donald Knuth as a means of evaluating implementations of the ALGOL 60 programming language. The aim of the test was to distinguish compilers that correctly implemented "recursion and non-local references" from those that did not.

There are quite a few ALGOL60 translators in existence which have been designed to handle recursion and non-local references properly, and I thought perhaps a little test-program may be of value. Hence I have written the following simple routine, which may separate the man-compilers from the boy-compilers.
