Twenty Questions

Twenty Questions is a spoken parlor game which encourages deductive reasoning and creativity. It originated in the United States and was played in the 19th century, it escalated in popularity during the late 1940s when it became the format for a successful weekly radio quiz program. In the traditional game, one player is chosen to be the answerer; that person does not reveal this to the others. All other players are questioners, they each take turns asking a question which can be answered with a simple "Yes" or "No." In variants of the game, multiple state answers may be included such as the answer "Maybe." The answerer answers each question in turn. Sample questions could be: "Is it bigger than a breadbox?" or "Can I put it in my mouth?" Lying is not allowed in the game. If a questioner guesses the correct answer, that questioner wins and becomes the answerer for the next round. If 20 questions are asked without a correct guess the answerer has stumped the questioners and gets to be the answerer for another round.

Careful selection of questions can improve the odds of the questioner winning the game. For example, a question such as "Does it involve technology for communications, entertainment or work?" can allow the questioner to cover a broad range of areas using a single question that can be answered with a simple "yes" or "no". If the answerer responds with "yes," the questioner can use the next question to narrow down the answer; the most popular variant is called "Animal, Mineral." This is taken from the Linnaean taxonomy of the natural world. In this version, the answerer tells the questioners at the start of the game whether the subject belongs to the animal, vegetable or mineral kingdom; these categories can produce odd technicalities, such as a wooden table being classified as a vegetable, or a belt being both animal and mineral, or vegetable, if made from plant fibers. Other versions specify that the item to be guessed should be in a given category, such as actions, famous people, etc. In Hungary, a similar game is named after Simon bar Kokhba.

A version of Twenty Questions called Yes and No is played as a parlour game by characters of Charles Dickens' A Christmas Carol. Similar to the aforementioned, there is another version known to English as a Second Language educators, played based on a given topic. There are many different ways. 20 Questions on "Educate, Learn", for example, was developed for the Austrian Federal Ministry of Education and Women's Affairs. The abstract mathematical version of the game where some answers may be wrong is sometimes called Ulam's game or the Rényi–Ulam game; the game suggests. The game is used as an example when teaching people about information theory. Mathematically, if each question is structured to eliminate half the objects, 20 questions will allow the questioner to distinguish between 220 or 1,048,576 objects. Accordingly, the most effective strategy for Twenty Questions is to ask questions that will split the field of remaining possibilities in half each time; the process is analogous to a binary search algorithm in computer science or successive approximation ADC in analog-to-digital signal conversion.

In 1901 Charles Sanders Peirce discussed factors in the economy of research that govern the selection of a hypothesis for trial — cheapness, intrinsic value, relation to other projects. He discussed the potential of Twenty Questions to single one subject out from among 220 and, pointing to skillful caution, Thus twenty skillful hypotheses will ascertain what two hundred thousand stupid ones might fail to do; the secret of the business lies in the caution which breaks a hypothesis up into its smallest logical components, only risks one of them at a time. He elaborated on how, if that principle had been followed in the investigation of light, its investigators would have saved themselves from half a century of work. Note that testing the smallest logical components of a hypothesis one at a time does not mean asking about, say, 1,048,576 subjects one at a time. Instead it means extracting aspects of a guess or hypothesis, asking, for example, "did an animal do this?" before asking "did a horse do this?".

That aspect of scientific method resembles a situation puzzle in facing a puzzling scenario at the start. Both games involve asking yes/no questions, but Twenty Questions places a greater premium on efficiency of questioning. A limit on their likeness to the scientific process of trying hypotheses is that a hypothesis, because of its scope, can be harder to test for truth than to test for falsity or vice versa. In developing the participatory anthropic principle, an interpretation of quantum mechanics, theoretical physicist John Archibald Wheeler used a variant on Twenty Questions, called Negative Twenty Questions, to show how the questions we choose to ask about the universe may dictate the answers we get. In this variant, the respondent does not choose or decide upon any particular or definite object beforehand, but only on a pattern of'Yes' or'No' answers; this variant requires the respondent to provide a consistent set of answers to successive

Laura (Capaccio)

Laura is a southern Italian village and hamlet of Capaccio, a municipality in the province of Salerno, Campania. As of 2001 its population was of 1,301. On September 9, 1943, the beaches of Laura and Paestum were the landing points of the U. S. Fifth Army during the Operation Avalanche, part of the Allied invasion of Italy. Located in the northern side of Cilentan Coast, nearby the mouth of Sele river, Laura lies a few km from the Ancient Greek city of Paestum and the village of Capaccio Scalo, it is 12 km far from Capaccio, 14 from Agropoli, 25 from Eboli, 22 from Battipaglia and 36 from Salerno. The inhabited area extends along the main road and by the Tyrrhenian coastline, part of the Nature Reserve Foce Sele-Tanagro; the urban expansion, as well as to the surrounding villages, began in the late 20th century, because of the seaside tourism and the proximity to the ruins of Paestum. Crossed in the middle by the provincial highway SP 175/B that links Salerno to Agropoli by the coast, Laura is few km far from the national highway SS 18 Naples-Reggio Calabria and from the railway stations of Capaccio-Roccadaspide and Paestum.

Evald Nielsen

Evald Nielsen was a Danish silversmith and long-standing master of the Goldsmith's Guild of Copenhagen and one of the leading men behind the organizing of the Danish gold- and silversmiths. Nielsen was born in Stubbekøbing on the island Falster in the southeast of Denmark. In 1887 his father, a coach builder, smashed his knee in a working accident and went bankrupt with his workshop; when the father died in 1893, the family was left in poverty. In 1893 Evald Nielsen was apprenticed to the workshop of Aug. Fleron in Copenhagen, first as a press operator as steel engraver. In 1900, when he had finished his training, he travelled and worked in Germany and France, he visited the World Exhibition in Paris 1900. In 1905 Evald Nielsen opened his own workshop in a cellar in Raadhusstræde, Copenhagen. At first he worked as silversmith as well as engraver, but after a few years he concentrated on silver producing and selling hollow ware and first of all cutlery. In 1914 his workshop employed 14 persons.

In 1918 his shop and workshop moved to Vester Voldgade 11 in Copenhagen, where the firm had its base for the following decade. In 1926 Evald Nielsen bought a property at Nygade 5 - a street, part of the main shopping area in Copenhagen, moved his shop to this building. In 1931 the shop was renovated and rebuild in the art deco style, attracting much attention among the Copenhageners of that time. In 1930 the workshop was moved from Vester Voldgade to rented premises in Ny Vestergade 7 some hundred meters east of Nygade. From 1927 and a decade onwards Evald Nielsen's oldest son, the silversmith Aage Weimar worked in the firm, until he opened his own workshop. Evald Nielsen's other son, Bjarne Weimar, finished his education as a chaser in 1929 and started working in his father's firm. In 1941 he was taken into partnership, he tried to carry on with the firm, when Evald Nielsen died in 1958, his attempt wasn't successful, the shop in Nygade closed in the spring of 1970. The workshop in Ny Vestergade was in 1958 let on lease to Ejnar Olsen, who produced to the shop in Nygade.

In 1967 the workshop was sold to Helge Hansen. The following year he moved the activities to Rødovre, where he had a workshop. Up to 2006 the firm was carried on in the name of Evald Nielsens Eftf. the last years with Helge Hansen's sons Harly Hansen and Søren Pedersen as owners. In 2006 they sold the firm and the rights to the Evald Nielsen-name and -design to silversmith Gregers Holt. Evald Nielsen opened his workshop the year. In the years to come Evald Nielsen put his mark on the Danish skønvirke-style. Contrary to Georg Jensen Evald Nielsen based his firm on his own design and only to a small extent used artists and architects as designers. During the first decades he himself designed jewellery, hollow cutlery, he generated his own style, among other things characterized by the so-called drawn out or stretched mountings holding the stones of the jewellery. In the 1930s his son Aage Weimar was attached to the firm, he worked with design, he took part in bringing Evald Nielsen into the art deco style with its tighter use of form.

Evald Nielsen sold his silver not only in Denmark. Today his works are appreciated by collectors in the two countries. Throughout his whole life Evald Nielsen was characterized by his wholehearted holding on to skilful craftsmanship and excellent quality. To him the trained craftsman was the one and only to design and create. "The professional skill and knowledge of the trade has always been essential in preserving the confidence between the goldsmith and the costumers," he in January 1935 wrote in Guldsmede-Bladet. Because of that he worked hard to organize the training of the employees at the workshops, among other things he in 1918 took part in planning and teaching at the first courses for gold- and silversmiths at the Danish Technological Institute. In 1913 Evald Nielsen became a member of the Goldsmith's Guild of Copenhagen. In 1918 he was elected master of the guild. From on he engaged himself in organizing work, building up an organization that could represent the Danish gold- and silversmiths in negotiations with the growing labor unions that defended the rights of the employees.

The most important step was the formation of Dansk Guldsmedemesterforening in 1920 with Evald Nielsen as the first chairman. From here he was engaged in a number of organizations, among other things he for many years was a member of the executive committee of The Confederation of Danish Employers. During the 1940s Evald Nielsen cut down on the organizing work, he resigned the chairmanship of Dansk Guldsmedemesterforening in 1946, shortly after his silver jubilee. In 1948 - after 30 years - he retired from the mastership of the Goldsmith's Guild of Copenhagen and was at that occasion made honorary master. Through his contribution Evald Nielsen to a high degree formed the basis of the organization of the Danish gold- and silversmiths, prevailing today. Silver from the workshop of Evald Nielsen is marked with "EN" or his full name: "Evald Nielsen". Chr. Rimestad: "EN - solist i sølv. En biografi om sølvsmeden Evald Nielsen".
