1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral.

In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions.

2013 (MMXIII) was a common year starting on Tuesday of the Gregorian calendar, the 2013th year of the Common Era (CE) and Anno Domini (AD) designations, the 13th year of the 3rd millennium and the 21st century, and the 4th year of the 2010s decade.

Year 204 (CCIV) was a leap year starting on Sunday of the Julian calendar. At the time, it was known as the Year of the Consulship of Cilo and Flavius (or, less frequently, year 957 Ab urbe condita). The denomination 204 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Benz, an old Germanic clan name dating to the fifth century (related to "bear", "war banner", "gau", or a "land by a waterway") also used in German (German pronunciation: [bɛnts] ) as an alternative for names such as Berthold, Bernhard, or Benedict, may refer to:

A drivetrain (also frequently spelled as drive train or sometimes drive-train) or transmission system, is the group of components that deliver mechanical power from the prime mover to the driven components. In automotive engineering, the drivetrain is the components of a motor vehicle that deliver power to the drive wheels. This excludes the engine or motor that generates the power. In marine applications, the drive shaft will drive a propeller, thruster, or waterjet rather than a drive axle, while the actual engine might be similar to an automotive engine. Other machinery, equipment and vehicles may also use a drivetrain to deliver power from the engine(s) to the driven components.

In contrast, the powertrain is considered to include both the engine and/or motor(s) as well as the drivetrain.

An oil is any nonpolar chemical substance that is composed primarily of hydrocarbons and is hydrophobic (does not mix with water) and lipophilic (mixes with other oils). Oils are usually flammable and surface active. Most oils are unsaturated lipids that are liquid at room temperature.

The general definition of oil includes classes of chemical compounds that may be otherwise unrelated in structure, properties, and uses. Oils may be animal, vegetable, or petrochemical in origin, and may be volatile or non-volatile. They are used for food (e.g., olive oil), fuel (e.g., heating oil), medical purposes (e.g., mineral oil), lubrication (e.g. motor oil), and the manufacture of many types of paints, plastics, and other materials. Specially prepared oils are used in some religious ceremonies and rituals as purifying agents.

Sport is a form of physical activity or game. Often competitive and organized, sports use, maintain, or improve physical ability and skills. They also provide enjoyment to participants and, in some cases, entertainment to spectators. Many sports exist, with different participant numbers, some are done by a single person with others being done by hundreds. Most sports take place either in teams or competing as individuals. Some sports allow a "tie" or "draw", in which there is no single winner; others provide tie-breaking methods to ensure one winner. A number of contests may be arranged in a tournament format, producing a champion. Many sports leagues make an annual champion by arranging games in a regular sports season, followed in some cases by playoffs.

Sport is generally recognised as system of activities based in physical athleticism or physical dexterity, with major competitions admitting only sports meeting this definition. Some organisations, such as the Council of Europe, preclude activities without any physical element from classification as sports. However, a number of competitive, but non-physical, activities claim recognition as mind sports. The International Olympic Committee who oversee the Olympic Games recognises both chess and bridge as sports. SportAccord, the international sports federation association, recognises five non-physical sports: chess, bridge, draughts, Go and xiangqi. However, they limit the number of mind games which can be admitted as sports. Sport is usually governed by a set of rules or customs, which serve to ensure fair competition. Winning can be determined by physical events such as scoring goals or crossing a line first. It can also be determined by judges who are scoring elements of the sporting performance, including objective or subjective measures such as technical performance or artistic impression.

Records of performance are often kept, and for popular sports, this information may be widely announced or reported in sport news. Sport is also a major source of entertainment for non-participants, with spectator sport drawing large crowds to sport venues, and reaching wider audiences through broadcasting. Sport betting is in some cases severely regulated, and in others integral to the sport.

According to A.T. Kearney, a consultancy, the global sporting industry is worth up to $620 billion as of 2013. The world's most accessible and practised sport is running, while association football is the most popular spectator sport.
