Amusement

Amusement is the state of experiencing humorous and entertaining events or situations, and is associated with enjoyment, happiness, laughter and pleasure.

Current studies have not yet reached consensus on the exact purpose of amusement, though theories have been advanced in the fields of psychology, psychiatry and sociology. In addition, the precise mechanism that causes a given element (image, sound, behavior, etc.) to be perceived as more or less 'amusing' than another, similar element to a particular individual is not clearly understood.

Amusement park

An amusement park (sometimes referred to as a funfair) or theme park is a group of entertainment attractions, rides, and other events in a location for the enjoyment of large numbers of people. Amusement parks have a fixed location, as opposed to travelling funfairs and traveling carnivals, and are more elaborate than simple city parks or playgrounds, usually providing attractions meant to cater specifically to certain age groups, as well as some that are aimed towards all ages. Theme parks, a specific type of amusement park, are usually much more intricately themed to a certain subject or group of subjects than normal amusement parks.

Amusement parks evolved from European fairs and pleasure gardens, which were created for people's recreation. World's fairs and expositions were another influence on the development of the amusement park industry.

In common language, the terms theme park and amusement park are often synonymous. However, a theme park can be regarded as a distinct style of amusement park. A theme park has landscaping, buildings, and attractions that are based on one or more specific themes or stories. Despite many older parks adding themed rides and areas, qualifying the park as a theme park, the first park built with the original intention of promoting a specific theme, Santa Claus Land, in Santa Claus, Indiana, did not open until 1946.Disneyland, located in Anaheim, California, built around the concept of encapsulating multiple theme parks into a single amusement park is often mistakenly cited as the first themed amusement park, but is instead the park that made the idea popular.

24-hour clock

The 24-hour clock is the convention of time keeping in which the day runs from midnight to midnight and is divided into 24 hours, indicated by the hours passed since midnight, from 0 to 23. This system is the most commonly used time notation in the world today, and is used by international standard ISO 8601. In the practice of medicine, the 24-hour clock is generally used in documentation of care as it prevents any ambiguity as to when events occurred in a patient's medical history. It is popularly referred to as military time in the United States, English-speaking Canada, Russia, and a handful of other countries where the 12-hour clock is still dominant.

Description

A time of day is written in the 24-hour notation in the form hh:mm (for example 01:23) or hh:mm:ss (for example, 01:23:45), where hh (00 to 23) is the number of full hours that have passed since midnight, mm (00 to 59) is the number of full minutes that have passed since the last full hour, and ss (00 to 59) is the number of seconds since the last full minute. In the case of a leap second, the value of ss may extend to 60. A leading zero is added for numbers under 10. This zero is optional for the hours, but very commonly used in computer applications, where many specifications require it (for example, ISO 8601).
