Time

Time is a measure in which events can be ordered from the past through the present into the future, and also the measure of durations of events and the intervals between them. Time is often referred to as the fourth dimension, along with the three spatial dimensions.

Time has long been a major subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems. Some simple definitions of time include "time is what clocks measure", which is a problematically vague and self-referential definition that utilizes the device used to measure the subject as the definition of the subject, and "time is what keeps everything from happening at once", which is without substantive meaning in the absence of the definition of simultaneity in the context of the limitations of human sensation, observation of events, and the perception of such events.

Waste

Waste and wastes are unwanted or unusable materials. Waste is any substance which is discarded after primary use, or it is worthless, defective and of no use.

The term is often subjective (because waste to one person is not necessarily waste to another) and sometimes objectively inaccurate (for example, to send scrap metals to a landfill is to inaccurately classify them as waste, because they are recyclable). Examples include municipal solid waste (household trash/refuse), hazardous waste, wastewater (such as sewage, which contains bodily wastes (feces and urine) and surface runoff), radioactive waste, and others.

Guest appearance

In show business, a guest appearance is the participation of an outsider performer (such as a musician or actor) in an event such as a music record or concert, show, etc., when the performer does not belong to the regular cast, band or other performing group. In music, such an outside performer is often referred to as a guest artist. In performance art, the terms guest role or guest star are also common, the latter term specifically indicating the guest appearance of a celebrity. The latter is often also credited as "special guest star" or "special musical guest star" by some production companies. A guest character is a character being portrayed within a fictional entertainment setting who is only involved as part of the plot once or a few times at most. A guest character has fewer appearances than main characters, supporting characters, and recurring characters.

In pop music, guest appearances are often described with the words featuring, with, or and. It is abbreviated in credit lists as feat., ft., f/, f.. In a television series, a guest star is an actor who appears in one or a few episodes. In radio and television shows, a guest star is a guest of the show who is a celebrity.

Tony Hawk

Anthony Frank "Tony" Hawk (born May 12, 1968), nicknamed "The Birdman", is an American former professional skateboarder and actor. Hawk is well known for completing the first documented 900 and for his licensed video game titles, published by Activision. He is widely considered to be one of the most successful and influential pioneers of modern vertical skateboarding.

In 2002, he created the "Boom Boom HuckJam", an extreme sports exhibition and tour that was launched in Las Vegas. Throughout his career, Hawk has made numerous appearances in films, other media, and his own series of video games. He has also been involved in various philanthropic activities, including his own Tony Hawk Foundation that helps to build skateparks in underprivileged areas. In 2014, Hawk was labeled as one of the "Most influential skateboarders of all-time" by FoxWeekly.

Early life

Tony Hawk was born on May 12, 1968 in Carlsbad, California, to Nancy and Frank Peter Rupert Hawk, and was raised in San Diego, California. When Hawk was young, he was described as being "hyperactive," and his mother says that he was "so hard on himself and expected himself to do so many things." One time, Hawk struck out in baseball and was so distraught that he hid in a ravine and had to be "physically coaxed out" by his father. His frustration with himself was so harsh that his parents had him psychologically evaluated at school. The results were that Tony was "gifted," he tested with an I.Q. of 144, and school advisers recommended placing him in advanced classes. Hawk attended Jean Farb Middle School from 1980 to 1981, and eventually returned for the show, Homecoming with Rick Reilly, where he set up a ramp and did a demonstration.
