Domino Toppling
Domino toppling is the activity of standing up dominoes in sequence known as a domino run and then triggering the first one in line to create a chain reaction also called the domino effect. A competition between two or more players to be first to have all one's dominoes fall is sometimes called a domino rally. If domino toppling is demonstrated to an audience it is called a domino show. Description Domino toppling is achieved by standing dominoes on end and arranging them in the desired patterns and sequences. Such a sequence is called a domino run. Using dominoes of different colours, the builders are able to create patterns and images. The dominoes can have different top and back colours, meaning that the dominoes display different colours before and after being toppled. Other tricks include three-dimensional stackings; shapes such as spirals and letters; Rube Goldberg machines; special toppling techniques, and special effects. Only the first domino should be toppled by hand in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Domino 02
Dominoes is a family of tile-based games played with gaming pieces, commonly known as dominoes. Each domino is a rectangular tile, usually with a line dividing its face into two square ''ends''. Each end is marked with a number of spots (also called '' pips'' or ''dots'') or is blank. The backs of the tiles in a set are indistinguishable, either blank or having some common design. The gaming pieces make up a domino set, sometimes called a ''deck'' or ''pack''. The traditional European domino set consists of 28 tiles, also known as pieces, bones, rocks, stones, men, cards or just dominoes, featuring all combinations of spot counts between zero and six. A domino set is a generic gaming device, similar to playing cards or dice, in that a variety of games can be played with a set. Another form of entertainment using domino pieces is the practice of domino toppling. The earliest mention of dominoes is from Song dynasty China found in the text ''Former Events in Wulin'' by Zhou Mi (1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Information Processing
Information processing is the change (processing) of information in any manner detectable by an observer. As such, it is a process that ''describes'' everything that happens (changes) in the universe, from the falling of a rock (a change in position) to the printing of a text file from a digital computer system. In the latter case, an information processor (the printer) is changing the form of presentation of that text file (from bytes to glyphs). The computers up to this period function on the basis of programs saved in the memory, having no intelligence of their own. In cognitive psychology Within the field of cognitive psychology, information processing is an approach to the goal of understanding human thinking in relation to how they process the same kind of information as computers (Shannon & Weaver, 1963). It arose in the 1940s and 1950s, after World War II (Sternberg & Sternberg, 2012). The approach treats cognition as essentially computational in nature, with ''mind'' b ...

Digital Signal (electronics)
A digital signal is a signal that represents data as a sequence of discrete values; at any given time it can only take on, at most, one of a finite number of values. This contrasts with an analog signal, which represents continuous values; at any given time it represents a real number within a continuous range of values. Simple digital signals represent information in discrete bands of analog levels. All levels within a band of values represent the same information state. In most digital circuits, the signal can have two possible valid values; this is called a binary signal or logic signal. They are represented by two voltage bands: one near a reference value (typically termed as ''ground'' or zero volts), and the other a value near the supply voltage. These correspond to the two values "zero" and "one" (or "false" and "true") of the Boolean domain, so at any given time a binary signal represents one binary digit (bit). Because of this discretization, relatively small chan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amplifier
An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the magnitude of a signal (a time-varying voltage or current). It may increase the power significantly, or its main effect may be to boost the voltage or current (power, voltage or current amplifier). It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a greater amplitude signal at its output. The ratio of output to input voltage, current, or power is termed gain (voltage, current, or power gain). An amplifier, by definition has gain greater than unity (if the gain is less than unity, the device is an attenuator). An amplifier can either be a separate piece of equipment or an electrical circuit contained within another device. Amplification is fundamental to modern electronics, and amplifiers are widely used in almost all electronic equipment. Amplifiers can be categorize ...

Lech Wałęsa
Lech Wałęsa (; ; born 29 September 1943) is a Polish statesman, dissident, and Nobel Peace Prize laureate, who served as the President of Poland between 1990 and 1995. After winning the 1990 election, Wałęsa became the first democratically elected President of Poland since 1926 and the first-ever Polish President elected in popular vote. A shipyard electrician by trade, Wałęsa became the leader of the Solidarity movement, and led a successful pro-democratic effort which in 1989 ended the Communist rule in Poland and ushered in the end of the Cold War. While working at the Lenin Shipyard (now Gdańsk Shipyard), Wałęsa, an electrician, became a trade-union activist, for which he was persecuted by the government, placed under surveillance, fired in 1976, and arrested several times. In August 1980, he was instrumental in political negotiations that led to the ground-breaking Gdańsk Agreement between striking workers and the government. He co-founded the Solidarity tr ...

Solidarity (Polish Trade Union)
Solidarity ( pl, „Solidarność”, ), full name Independent Self-Governing Trade Union "Solidarity" (, abbreviated ''NSZZ „Solidarność”'' ), is a Polish trade union founded in August 1980 at the Lenin Shipyard in Gdańsk, Poland. Subsequently, it was the first independent trade union in a Warsaw Pact country to be recognised by the state. The union's membership peaked at 10 million in September 1981, representing one-third of the country's working-age population. Solidarity's leader Lech Wałęsa was awarded the Nobel Peace Prize in 1983 and the union is widely recognised as having played a central role in the end of Communist rule in Poland. In the 1980s, Solidarity was a broad anti-authoritarian social movement, using methods of civil resistance to advance the causes of workers' rights and social change. Government attempts in the early 1980s to destroy the union through the imposition of martial law in Poland and the use of political repression failed. Operati ...

Fall Of The Berlin Wall
The fall of the Berlin Wall (german: Mauerfall) on 9 November 1989, during the Peaceful Revolution, was a pivotal event in world history which marked the destruction of the Berlin Wall and the figurative Iron Curtain and one of the series of events that started the fall of communism in Eastern and Central Europe, preceded by the Solidarity Movement in Poland. The fall of the inner German border took place shortly afterwards. An end to the Cold War was declared at the Malta Summit three weeks later and the German reunification took place in October the following year. Background Opening of the Iron Curtain The opening of the Iron Curtain between Austria and Hungary at the Pan-European Picnic on 19 August 1989 set in motion a peaceful chain reaction, at the end of which there was no longer an East Germany and the Eastern Bloc had disintegrated. Extensive advertising for the planned picnic was made by posters and flyers among the GDR holidaymakers in Hungary. It was the larges ...

Acrobatics
Acrobatics () is the performance of human feats of balance, agility, and motor coordination. Acrobatic skills are used in performing arts, sporting events, and martial arts. Extensive use of acrobatic skills are most often performed in acro dance, circus, and gymnastics, and to a lesser extent in other athletic activities including ballet, slacklining and diving. Although acrobatics is most commonly associated with human body performance, the term is used to describe other types of performance, such as aerobatics. History Acrobatic traditions are found in many cultures, and there is evidence that the earliest such traditions occurred thousands of years ago. For example, Minoan art from c. 2000 BC contains depictions of acrobatic feats on the backs of bulls. Ancient Greeks practiced acrobatics, and the noble court displays of the European Middle Ages would often include acrobatic performances that included juggling. In China, acrobatics have been a part of the culture si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
