Eurodance (also known as Dance and Hands Up in Europe) is a genre of electronic dance music that originated in the late 1980s or early 1990s primarily in Europe. It combines many elements from House, Techno, Hi-NRG and especially Italo-Disco. Starting in the early 1990s and continuing to the present day, Eurodance production continues to evolve with a more modernized style that incorporates elements from Trance and Techno music.
Eurodance music is heavily influenced by the utilization of rich melodic vocals, either exclusively by itself or inclusively with rapped verses. This, combined with cutting-edge synthesizer, strong bass rhythm and melodic hooks establishes the core foundation of Eurodance music.

A thyratron is a type of gas filled tube used as a high energy electrical switch and controlled rectifier. Triode, tetrode and pentode variations of the thyratron have been manufactured in the past, though most are of the triode design. Because of the gas fill, thyratrons can handle much greater currents than similar hard vacuum valves/tubes since the positive ions carry considerable current. Gases used include mercury vapor, xenon, neon, and (in special high-voltage applications or applications requiring very short switching times) hydrogen. Unlike a vacuum tube, a thyratron cannot be used to amplify signals linearly.
A solid-state device with similar operating characteristics is the silicon controlled rectifier (SCR).

A breadboard (protoboard) is a construction base for a one-of-a-kind electronic circuit, a prototype. In modern times the term is commonly used to refer to a particular type of breadboard, the solderless breadboard (plugboard).
Because the solderless breadboard does not require soldering, it is reusable, and thus can be used for temporary prototypes and experimenting with circuit design more easily. Other, often historic, breadboard types don't have this property. This is also in contrast to stripboard (veroboard) and similar prototyping printed circuit boards, which are used to build more permanent soldered prototypes or one-offs, and cannot easily be reused. A variety of electronic systems may be prototyped by using breadboards, from small analog and digital circuits to complete central processing units (CPUs).

Wunderwaffe (German pronunciation: [ˈvʊndɐˌvafə]) is German for "wonder weapon" and was a term assigned during World War II by the German propaganda ministry to a few revolutionary "superweapons". Most of these weapons however remained more or less feasible prototypes, or reached the combat theatre too late, and in too insignificant numbers (if at all) to have a military effect. A derisive abbreviation of the term emerged: Wuwa, pronounced "voo-vah".
The V-weapons, which were developed earlier, and saw considerable deployment especially against Great Britain, trace back to the same pool of highly inventive armament concepts. Therefore, they are also included here.
Although the Wunderwaffen failed to meet their strategic objective of turning the tides of World War II in Nazi Germany's favor at a time when the war was already strategically lost, they represented designs and prototypes that were extremely advanced for their time.

The Vegetable Lamb of Tartary (Latin: Agnus scythicus or Planta Tartarica Barometz) is a legendary zoophyte of central Asia, believed to grow sheep as its fruit. The sheep were connected to the plant by an umbilical cord and grazed the land around the plant. When all the plants were gone, both the plant and sheep died.
Although it owed its currency in medieval thought as a way of explaining the existence of cotton, underlying the myth is a real plant, Cibotium barometz, a fern of the genus Cibotium. It was known under various other names including the Scythian Lamb, and the Barometz. The 'lamb' is produced by removing the leaves from a short length of the fern's woolly rhizome. When the rhizome is inverted, it fancifully resembles a woolly lamb with the legs being formed by the severed petiole bases. The Tradescant Museum of Garden History has one under glass.

Herding is the act of bringing individual animals together into a group (herd), maintaining the group and moving the group from place to place—or any combination of those. While the layperson uses the term "herding", most individuals involved in the process term it mustering, "working stock" or droving.
Some animals instinctively gather together as a herd. A group of animals fleeing a predator will demonstrate herd behavior for protection; while some predators, such as wolves and dogs have instinctive herding abilities derived from primitive hunting instincts. Instincts in herding dogs and trainability can be measured at noncompetitive herding tests. Dogs exhibiting basic herding instincts can be trained to compete in herding and stock dog trials. Sperm whales have also been observed teaming up to herd prey in a coordinated feeding behavior.

Shechita (Hebrew:שְׁחִיטָה; also transliterated shechitah, shehitah, shehita) is the ritual slaughter of mammals and birds according to Jewish dietary laws. The act is performed by severing the trachea, oesophagus, carotid arteries and jugular veins using an extremely sharp blade ("chalef"), and allowing the blood to drain out.
The animal must be killed with respect and compassion by a shochet (ritual slaughterer), a religious Jew who is duly licensed and trained. The animal can be in a number of positions; when the animal is lying on its back, this is referred to as shechita munachat; in a standing position it is known as shechita me'umedet.
If the hindquarters of kosher mammals are to be eaten by Jews, they must be 'porged' - stripped of veins, chelev (caul fat and suet) and sinews in accordance with a strict procedure.[Because of the expense of porging and the skill required to properly separate out the forbidden parts, a large portion of the meat of kosher mammals slaughtered through shechita in the United States winds up on the non-kosher market.

However, in various contexts, different (and sometimes opposing) political groups have used the term "Marxism–Leninism" to describe the ideology that they claimed to be upholding.

The unknot arises in the mathematical theory of knots. Intuitively, the unknot is a closed loop of rope without a knot in it. A knot theorist would describe the unknot as an image of any embedding that can be deformed, i.e. ambient-isotoped, to the standard unknot, i.e. the embedding of the circle as a geometrically round circle. The unknot is also called the trivial knot. An unknot is the identity element with respect to the knot sum operation.

A superorganism is an organism consisting of many organisms. This is usually meant to be a social unit of eusocial animals, where division of labour is highly specialised and where individuals are not able to survive by themselves for extended periods of time. Ants are the best-known example of such a superorganism, while the naked mole rat is a famous example of the eusocial mammal. The technical definition of a superorganism is "a collection of agents which can act in concert to produce phenomena governed by the collective," phenomena being any activity "the hive wants" such as ants collecting food or bees choosing a new nest site.

It is also known as "eleventy", a term made famous by linguist and author J. R. R. Tolkien (Bilbo Baggins celebrates his eleventy-first birthday at the beginning of The Lord of the Rings) and derived from the Old English hund endleofantig. When the word eleventy is used, it may indicate the exact number (110), or more commonly an indefinite large number such as gazillion.

Capsicum is a genus of flowering plants in the nightshade family, Solanaceae. Its species are native to the Americas, where they have been cultivated for thousands of years by the people of the tropical Americas, and are now cultivated worldwide. Some of the members of Capsicum are used as spices, vegetables, and medicines. The fruit of Capsicum plants have a variety of names depending on place and type. They are commonly called chili pepper, red or green pepper, or sweet pepper in Britain, and typically just capsicum in Australia, New Zealand, and India. The large mild form is called bell pepper in the U.S. and Canada. They are called paprika in some other countries (although paprika can also refer to the powdered spice made from various capsicum fruit). The generic name is derived from the Greek word κάπτω (kapto), meaning "to bite" or "to swallow." The name "pepper" came into use because of their similar flavour to the condiment black pepper, Piper nigrum, although there is no botanical relationship with this plant, or with Sichuan pepper.
