8 (number)
8 (eight) is the natural number following 7 and preceding 9. Etymology English ''eight'', from Old English '', æhta'', Proto-Germanic ''*ahto'' is a direct continuation of Proto-Indo-European '' *oḱtṓ(w)-'', and as such cognate with Greek and Latin , both of which stems are reflected by the English prefix oct(o)-, as in the ordinal adjective ''octaval'' or ''octavary'', the distributive adjective is '' octonary''. The adjective ''octuple'' (Latin ) may also be used as a noun, meaning "a set of eight items"; the diminutive '' octuplet'' is mostly used to refer to eight siblings delivered in one birth. The Semitic numeral is based on a root ''*θmn-'', whence Akkadian ''smn-'', Arabic ''ṯmn-'', Hebrew ''šmn-'' etc. The Chinese numeral, written ( Mandarin: ''bā''; Cantonese: ''baat''), is from Old Chinese ''*priāt-'', ultimately from Sino-Tibetan ''b-r-gyat'' or ''b-g-ryat'' which also yielded Tibetan '' brgyat''. It has been argued that, as the cardinal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
In Search Of The Fourth Chord
''In Search of the Fourth Chord'' is the twenty-eighth studio album by English rock band Status Quo, released on 17 September 2007. The title is a tongue-in-cheek reference to the rumour that the group always plays the same three chords, and a reference to the album ''In Search of the Lost Chord'' by British rock band the Moody Blues. The album's artwork is a parody of the ''Indiana Jones'' films. The album saw the return of producer Pip Williams for the first time since 1996's '' Don't Stop''. It entered the UK Albums Chart at number 15. The track "Bad News" also marks bassist John "Rhino" Edwards' first lead vocal on an original Status Quo song: his son Freddie also plays the guitar solo on the track. This track and "Gravy Train" (sung by Parfitt) are also the first two Status Quo tracks that were written solely by John Edwards. Track listing # " Beginning of the End" (Francis Rossi, John Edwards) – 4:23 # "Alright" (Rick Parfitt, Wayne Morris) – 4:12 # "Pennsylvania B ...

Microphone
A microphone, colloquially called a mic (), or mike, is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and television broadcasting. They are also used in computers and other electronic devices, such as mobile phones, for recording sounds, speech recognition, Voice over IP, VoIP, and other purposes, such as Ultrasonic transducer, ultrasonic sensors or knock sensors. Several types of microphone are used today, which employ different methods to convert the air pressure variations of a sound wave to an electrical signal. The most common are the dynamic microphone, which uses a coil of wire suspended in a magnetic field; the condenser microphone, which uses the vibrating Diaphragm (acoustics), diaphragm as a capacitor ...

Figure Eight (angling)
The figure eight is a technique used by anglers to fish specifically for the muskellunge. It has been developed due to the nature of the fish's hunting style. Essentially, the figure eight is a final enticement performed by the angler just before lifting the lure out of the water for another cast. To help visualize the concept, think of a roller coaster. As the lure is moved from side to side, it also moves up and down. The figure eight is named after the pattern in which the angler pulls the lure through the water next to the boat A boat is a watercraft of a large range of types and sizes, but generally smaller than a ship, which is distinguished by its larger size or capacity, its shape, or its ability to carry boats. Small boats are typically used on inland waterways s ... in an attempt to get a following fish to bite. The muskellunge is known for “following” a lure up to the boat rather than immediately striking it. Anglers use different tactics to influence a follo ...

English Country Dance
A country dance is any of a very large number of social dances of a type that originated in England in the British Isles; it is the repeated execution of a predefined sequence of figures, carefully designed to fit a fixed length of music, performed by a group of people, usually in couples, in one or more sets. The figures involve interaction with your partner and/or with other dancers, usually with a progression so that you dance with everyone in your set. It is common in modern times to have a "caller" who teaches the dance and then calls the figures as you dance. Country dances are done in many different styles. As a musical form written in or time, the contredanse was used by Beethoven and Mozart. Beethoven's 6 Ecosaises WoO83 are dated to 1806. Mozart's 6 Ländlerische Tänze, K.606 are dated to 1791. Introduced to South America by French immigrants, Country Dance had great influence upon Latin American music as contradanza. The ''Anglais'' (from the French word meanin ...

Figure 8 (belay Device)
The figure 8 belay device is a piece of metal (usually an aluminum alloy) in the shape of an 8 with one large end and one small end. Usage This device utilizes a large surface area in contact with a climbing rope to provide sufficient friction along with the proper technique to be used as a belay device or for rappelling. A figure 8 (sometimes just referred to as an 8) is used in conjunction with a climbing harness and locking carabiner to control a belayed climber's descent, or one's own descent when rappelling. Pros Figure-eights offer a smooth controlled descent when rappelling and lowering climbers. They can be used with nearly any diameter climbing rope A dynamic rope is a specially constructed, somewhat elastic rope used primarily in rock climbing, ice climbing, and mountaineering Mountaineering, mountain climbing, or alpinism is a set of outdoor activities that involves ascending moun ... and don't get as hot as other friction devices because of their ability ...

Man Overboard Rescue Turn
A man overboard rescue turn (or person overboard) is a shiphandling manoeuvre usually implemented immediately upon learning of a person having gone overboard into the sea. To bring a vessel closer to the person's location, implementations of the principles described are: the Anderson turn (or single turn), the quick turn (also known as the Q-turn or the figure eight turn), the Williamson turn, and the Scharnow turn. The choice of manoeuvre is dependent on several factors, including: * Location of the casualty * Whether the casualty is seen going overboard immediately or if their missing is delayed * Whether the ship is using engines or using sails * The space available for the vessel to steer * The training of the crew involved. Ideally, in any man overboard scenario, the casualty should be approached with the vessel downwind of the persons position, with the vessel moving upwind. The man overboard rescue turn is often carried out as part of regular drills on merchant ships a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noseband
A noseband is the part of a horse's bridle that encircles the nose and jaw of the horse. In English riding, where the noseband is separately attached to its own headstall or crownpiece, held independently of the bit, it is often called a cavesson or caveson noseband. In other styles of riding, a simple noseband is sometimes attached directly to the same headstall as the bit. Development A noseband may have been one of the first tools used by humans to domesticate and ride horses. The bit developed later. The noseband was originally made of leather or rope. After the invention of the bit, the noseband was, in some cultures, demoted to a halter worn beneath the bridle that allowed the rider to remove the bit from the horse's mouth after work and leave a restraining halter on underneath, or to tie the horse by this halter, instead of by the bit, which could result in damage to the horse's mouth if it panicked. However, its ability to hold a horse's mouth shut over the bit was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riding Figures
{{Unreferenced, date=August 2023 Riding figures are prescribed paths a horse is ridden on in a riding arena, usually for training purposes. Figures may also be performed out in a field or other open area, but a riding arena provides markers that can help indicate the correctness in the size or shape of a figure. Purposes of ring figures Ring figures are a valuable training aid, giving the rider feedback as to his horse's training and weaknesses. A poorly executed ring figure may point out where the rider is lacking in control, and areas in which the horse needs additional training. For example, when riding down the diagonal, a rider may struggle to keep his horse on the correct path, suggesting issues with straightness. A poorly performed 20-meter circle may indicate that the horse is not truly between the aids, perhaps falling out through a shoulder, or that the rider is sitting crookedly. Figures are required components of dressage tests, are used in reining competition, and m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compulsory Figures
Compulsory figures or school figures were formerly a segment of figure skating, and gave the sport its name. They are the "circular patterns which skaters trace on the ice to demonstrate skill in placing clean turns evenly on round circles". For approximately the first 50 years of figure skating as a sport, until 1947, compulsory figures made up 60 percent of the total score at most competitions around the world. These figures continued to dominate the sport, although they steadily declined in importance, until the International Skating Union (ISU) voted to discontinue them as a part of competitions in 1990. Learning and training in compulsory figures instilled discipline and control; some in the figure skating community considered them necessary to teach skaters basic skills. Skaters would train for hours to learn and execute them well, and competing and judging figures would often take up to eight hours during competitions. Skaters traced compulsory figures, and were judged acco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Figure 8 Roller Coaster
Figure 8 roller coasters are a category of roller coasters where the train (roller coaster), train runs through a figure 8 shaped course before returning to the boarding station. This design was one of the first designs to be featured in roller coaster design, along with the out and back roller coaster. The figure 8 design allowed for more turns than the out and back design, offering riders an alternative experience. An early and famous example of a Figure 8 is the Leap the Dips at Lakemont Park, in Altoona, Pennsylvania. Many figure 8 roller coasters carry the name "Figure 8." Layout In a figure 8 track layout, the track crosses over itself, forming an "8" shape. The ''double figure eight'' is a variation where the track contains two separate figure-eight shapes. Some examples include the Cobra at Six Flags Discovery Kingdom and the Harley Quinn Crazy Train at Six Flags Great Adventure. Early figure 8 coasters were typically wooden Side friction roller coaster, side fricti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Figure 8 Racing
Figure 8 racing is a type of stock car racing in which automobiles race on an " 8"-shaped track that purposely intersects itself, increasing the risk of collisions. Such contact between the participating vehicles, or at least the risk of such an occurrence, is an intentional part of the sport, with the intent being to damage them over the course of the race. Figure 8 racing is most common and popular in the United States and Canada, and can be seen as the North American equivalent to the European motorsport of banger racing, which also uses modified derelict older-model cars in races where vehicle damage is an integral feature. Track Racing is done on a track shaped like an "8". The cars cross paths at an intersection at the center of the "8", which is known as the "crossover" or the "X". Because of this layout, crashes are common. Figure 8 racing is a unique form of motorsport that requires strict attention to timing to successfully navigate the crossover. In Canada, figure 8 ...
