1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of unit length is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0.

The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the smallest possible difference between two distinct natural numbers.

The unique mathematical properties of the number have led to its unique uses in other fields, ranging from science to sports. It commonly denotes the first, leading, or top thing in a group.

A blender (sometimes called a mixer or liquidiser in British English) is a kitchen and laboratory appliance used to mix, crush, purée or emulsify food and other substances. A stationary blender consists of a blender container with a rotating metal or plastic blade at the bottom, powered by an electric motor that is in the base. Some powerful models can also crush ice and other frozen foods. The newer immersion blender configuration has a motor on top connected by a shaft to a rotating blade at the bottom, which can be used with any container.

A cookbook or cookery book is a kitchen reference containing recipes.

Cookbooks may be general, or may specialize in a particular cuisine or category of food.

Recipes in cookbooks are organized in various ways: by course (appetizer, first course, main course, dessert), by main ingredient, by cooking technique, alphabetically, by region or country, and so on. They may include illustrations of finished dishes and preparation steps; discussions of cooking techniques, advice on kitchen equipment, ingredients, tips, and substitutions; historical and cultural notes; and so on.

Cookbooks may be written by individual authors, who may be chefs, cooking teachers, or other food writers; they may be written by collectives; or they may be anonymous. They may be addressed to home cooks, to professional restaurant cooks, to institutional cooks, or to more specialized audiences.

Some cookbooks are didactic, with detailed recipes addressed to beginners or people learning to cook particular dishes or cuisines; others are simple aide-memoires, which may document the composition of a dish or even precise measurements, but not detailed techniques.

In everyday use and in kinematics, the speed (commonly referred to as v) of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity. The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is the magnitude of velocity (a vector), which indicates additionally the direction of motion.

Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph). For air and marine travel, the knot is commonly used.

The fastest possible speed at which energy or information can travel, according to special relativity, is the speed of light in vacuum c = 299792458 metres per second (approximately 1079000000 km/h or 671000000 mph). Matter cannot quite reach the speed of light, as this would require an infinite amount of energy. In relativity physics, the concept of rapidity replaces the classical idea of speed.

Variable may refer to:

• Variable (computer science), a symbolic name associated with a value and whose associated value may be changed
• Variable (mathematics), a symbol that represents a quantity in a mathematical expression, as used in many sciences
• Variable (research), a logical set of attributes
• Variable star, a type of astronomical star
• "The Variable", an episode of the television series Lost
