Drill Book
A dot book (also dotbook or dot-book or drill book) is a small notebook utilized by marching bands (especially high school Marching_band#Types_of_marching_bands, show bands and Drum and bugle corps (modern), drum corps) in order to aid the learning of formations Marching band#Field marching, on a field. The dot book was invented by Leslie Allard, a prominent high school band instructor and all-star percussionist. The name is derived from the use of dots on drill sheets which symbolize players on the field: a dot book focuses on the owner's particular dots and other marchers the player may have to guide (use to determine an adjusted location). The general layout of a dot book contains the "longitudes" and "latitudes" of an American football#Field and players, American football field. However, a cartesian coordinate system (x/y) is rarely used, rather an alternative system of chart, plotting players as dots on a grid and some jargon is used.

Notebook
A notebook (also known as a notepad, writing pad, drawing pad, or legal pad) is a book or stack of paper pages that are often ruled and used for purposes such as note-taking, journaling or other writing, drawing, or scrapbooking. History Early history During the fourteenth and fifteenth centuries, notebooks were often made by hand at home by drawing on them into gatherings that were then bound at a later date. The pages were blank and every notekeeper had to make ruled lines across the paper. Making and keeping notebooks was such an important information-management technique that children learned its skills in school. Legal pad According to a legend, Thomas W. Holley of Holyoke, Massachusetts, invented the legal pad around the year 1888 when he innovated the idea to collect all the sortings, various sorts of sub-standard paper scraps from various factories, and stitch them together in order to sell them as pads at an affordable and fair price. In about 1900, the latt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marching Band
A marching band is a group of instrumental musicians who perform while marching, often for entertainment or competition. Instrumentation typically includes brass, woodwind, and percussion instruments. Most marching bands wear a uniform, often of a military-style, that includes an associated organization's colors, name or symbol. Most high school marching bands, and some college marching bands, are accompanied by a color guard, a group of performers who add a visual interpretation to the music through the use of props, most often flags, rifles, and sabres. Marching bands are generally categorized by function, size, age, instrumentation, marching style, and type of show they perform. In addition to traditional parade performances, many marching bands also perform field shows at sporting events and marching band competitions. Increasingly, marching bands perform indoor concerts that implement many songs, traditions, and flair from outside performances. In some cases, at higher ...

Drum And Bugle Corps (modern)
A modern drum and bugle corps is a musical marching unit consisting of brass instruments, percussion instruments, electronic instruments, and color guard. Typically operating as independent non-profit organizations, corps perform in competitions, parades, festivals, and other civic functions. Participants of all ages are represented within the corps activity, but the majority are between the ages of 13 and 22 and are members of corps within Drum Corps International or Drum Corps Associates. Competitive summer drum corps participate in summer touring circuits, such as Drum Corps International (DCI) and Drum Corps Associates (DCA). Corps prepare a new show each year, approximately 8–12 minutes in length, and refine it throughout the summer tour. Shows are performed on football fields and are judged in various musical and visual categories, or "captions". Musical repertoires vary widely among corps and include symphonic, jazz, big band, contemporary, rock, wind band, vocal, r ...

Drill Sheet
A drill is a tool used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driverchuck. Hand-operated types are dramatically decreasing in popularity and cordless battery-powered ones proliferating due to increased efficiency and ease of use. Drills are commonly used in woodworking, metalworking, construction, machine tool fabrication, construction and utility projects. Specially designed versions are made for miniature applications. History Around 35,000 BC, ''Homo sapiens'' discovered the benefits of the application of rotary tools. This would have rudimentarily consisted of a pointed rock being spun between the hands to bore a hole through another material. This led to the hand drill, a smooth stick, that was sometimes attached to flint point, and was rubbed between the palms. This was used by many ancient civilizations around the world including the Mayans. The earliest perforated artifacts, such as bone, ivory, shells, and antlers ...

Guide
A guide is a person who leads travelers, sportspeople, or tourists through unknown or unfamiliar locations. The term can also be applied to a person who leads others to more abstract goals such as knowledge or wisdom. Travel and recreation Explorers in the past venturing into territory unknown by their own people invariably hired guides. Military explorers Lewis and Clark were hired by the United States Congress to explore the Pacific Northwest. They in turn hired the better qualified Native American Sacagawea to help them. Wilfred Thesiger hired guides in the deserts that he ventured into, such as Kuri on his journey to the Tibesti Mountains in 1938. Tour guide Tour guides lead visitors through tourist attractions and give information about the attractions' natural and cultural significance. Often, they also act as interpreters for travelers who do not speak the local language. Automated systems like audio tours are sometimes substituted for human tour guides. Tour operators ...

Longitude
Longitude (, ) is a geographic coordinate that specifies the east–west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Meridians are semicircular lines running from pole to pole that connect points with the same longitude. The prime meridian defines 0° longitude; by convention the International Reference Meridian for the Earth passes near the Royal Observatory in Greenwich, England on the island of Great Britain. Positive longitudes are east of the prime meridian, and negative ones are west. Because of the Earth's rotation, there is a close connection between longitude and time measurement. Scientifically precise local time varies with longitude: a difference of 15° longitude corresponds to a one-hour difference in local time, due to the differing position in relation to the Sun. Comparing local time to an absolute measure of time allows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latitude
In geography, latitude is a coordinate that specifies the north– south position of a point on the surface of the Earth or another celestial body. Latitude is given as an angle that ranges from –90° at the south pole to 90° at the north pole, with 0° at the Equator. Lines of constant latitude, or ''parallels'', run east–west as circles parallel to the equator. Latitude and ''longitude'' are used together as a coordinate pair to specify a location on the surface of the Earth. On its own, the term "latitude" normally refers to the ''geodetic latitude'' as defined below. Briefly, the geodetic latitude of a point is the angle formed between the vector perpendicular (or ''normal'') to the ellipsoidal surface from the point, and the plane of the equator. Background Two levels of abstraction are employed in the definitions of latitude and longitude. In the first step the physical surface is modeled by the geoid, a surface which approximates the mean sea level over the ocean ...

American Football
American football (referred to simply as football in the United States and Canada), also known as gridiron, is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end. The offense, the team with possession of the oval-shaped football, attempts to advance down the field by running with the ball or passing it, while the defense, the team without possession of the ball, aims to stop the offense's advance and to take control of the ball for themselves. The offense must advance at least ten yards in four downs or plays; if they fail, they turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the drive. Points are scored primarily by advancing the ball into the opposing team's end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal. The team with the most points at the end of a game wins. American football evolved in the United States, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cartesian Coordinate System
A Cartesian coordinate system (, ) in a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length. Each reference coordinate line is called a ''coordinate axis'' or just ''axis'' (plural ''axes'') of the system, and the point where they meet is its ''origin'', at ordered pair . The coordinates can also be defined as the positions of the perpendicular projections of the point onto the two axes, expressed as signed distances from the origin. One can use the same principle to specify the position of any point in three-dimensional space by three Cartesian coordinates, its signed distances to three mutually perpendicular planes (or, equivalently, by its perpendicular projection onto three mutually perpendicular lines). In general, ''n'' Cartesian coordinates (an element of real ''n''-space) specify the point in an ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
