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.

Eighteen or 18 may refer to:

• 18 (number)
• One of the years 18 BC, AD 18, 1918, 2018

2 (two) is a number, numeral and digit. It is the natural number following 1 and preceding 3. It is the smallest and the only even prime number.

Because it forms the basis of a duality, it has religious and spiritual significance in many cultures.

Year 230 (CCXXX) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Agricola and Clementinus (or, less frequently, year 983 Ab urbe condita). The denomination 230 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.

5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number.

Humans, and many other animals, have 5 digits on their limbs.

In thermodynamics, heat is energy in transfer between a thermodynamic system and its surroundings by modes other than thermodynamic work and transfer of matter. Such modes are microscopic, mainly thermal conduction, radiation, and friction, as distinct from the macroscopic modes, thermodynamic work and transfer of matter. For a closed system (transfer of matter excluded), the heat involved in a process is the difference in internal energy between the final and initial states of a system, and subtracting the work done in the process. For a closed system, this is the formulation of the first law of thermodynamics.

Calorimetry is measurement of quantity of energy transferred as heat by its effect on the states of interacting bodies, for example, by the amount of ice melted or by change in temperature of a body.

In the International System of Units (SI), the unit of measurement for heat, as a form of energy, is the joule (J).

With various other meanings, the word 'heat' is also used in engineering, and it occurs also in ordinary language, but such are not the topic of the present article.

The Mini (developed as ADO15) is a small, two-door, four-seat car produced by the British Motor Corporation (BMC) and its successors, from 1959 until 2000. Minus a brief hiatus, original Minis were built for four decades and sold during five, from the last year of the 1950s into the last year of the 20th century, over a single generation, as fastbacks, estates, and convertibles.

The original Mini is considered an icon of 1960s British popular culture. Its space-saving transverse engine and front-wheel drive layout – allowing 80% of the area of the car's floorpan to be used for passengers and luggage – influenced a generation of car makers. In 1999, the Mini was voted the second-most influential car of the 20th century, behind the Ford Model T, and ahead of the Citroën DS and Volkswagen Beetle. The front-wheel-drive, transverse-engine layout were used in many other "supermini" style car designs such as Honda N360 (1967), Nissan Cherry (1970), and Fiat 127 (1971). The layout was also adapted for larger subcompact designs.

This distinctive two-door car was designed for BMC by Sir Alec Issigonis. It was manufactured at the Longbridge plant in Birmingham, England located next to BMC's headquarters and at the former Morris Motors plant at Cowley near Oxford, in the Victoria Park/Zetland British Motor Corporation (Australia) factory in Sydney, Australia, and later also in Spain (Authi), Belgium, Italy (Innocenti), Chile, Malta, Portugal, South Africa, Uruguay, Venezuela, and Yugoslavia (IMV).

The Italian version of the Mini was produced by Innocenti in Milan and it was sold under the "Innocenti Mini" marque. Innocenti was also producing Lambretta scooters at that time.

The Mini Mark I had three major UK updates: the Mark II, the Clubman, and the Mark III. Within these was a series of variations, including an estate car, a pick-up, a van, and the Mini Moke, a jeep-like buggy.

The performance versions, the Mini Cooper and Cooper "S", were successful as both race and rally cars, winning the Monte Carlo Rally in 1964, 1965, and 1967. In 1966, the first-placed Mini (along with nine other cars) was disqualified after the finish, under a controversial decision that the car's headlights were against the rules.

In August 1959, the Mini was marketed under the Austin and Morris names, as the Austin Seven and Morris Mini-Minor. The Austin Seven was renamed Austin Mini in January 1962 and Mini became a marque in its own right in 1969. In 1980, it once again became the Austin Mini, and in 1988, just "Mini" (although the "Rover" badge was applied on some models exported to Japan).

BMW acquired the Rover Group (formerly British Leyland) in 1994, and sold the greater part of it in 2000, but retained the rights to build cars using the Mini name. Retrospectively, the car is known as the "Classic Mini" to distinguish it from the modern, BMW-influenced MINI family of vehicles produced since 2000.

A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic or pneumatic energy.

Mechanical pumps serve in a wide range of applications such as pumping water from wells, aquarium filtering, pond filtering and aeration, in the car industry for water-cooling and fuel injection, in the energy industry for pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry, pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and penile prosthesis.

When a pump contains two or more pump mechanisms with fluid being directed to flow through them in series, it is called a multi-stage pump. Terms such as two-stage or double-stage may be used to specifically describe the number of stages. A pump that does not fit this description is simply a single-stage pump in contrast.

In biology, many different types of chemical and biomechanical pumps have evolved; biomimicry is sometimes used in developing new types of mechanical pumps.

Ton is any of several units of measure of mass, volume or force. It has a long history and has acquired several meanings and uses.

As a unit of mass, ton can mean:

• the long ton, which is 2,240 pounds (1,016.0 kilograms)
• the tonne, also called the metric ton, which is 1,000 kilograms (about 2,204.6 pounds) or 1 megagram.
• the short ton, which is 2,000 pounds (907.2 kilograms)

Its original use as a unit of volume has continued in the capacity of cargo ships and in units such as the freight ton and a number of other units, ranging from 35 to 100 cubic feet (0.99 to 2.83 m³) in size. Recent specialized uses include the ton as a means of truck classification. It can also be used as a unit of energy, or in refrigeration as a unit of power, sometimes called a ton of refrigeration.

Because the ton (of any system of measuring weight) is usually the heaviest unit named in colloquial speech, its name also has figurative uses, singular and plural, informally meaning a large amount or quantity, or to a great degree, as in "There's a ton of bees in this hive," "We have tons of homework," and "I love you a ton."

The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI).
