Machine

A machine is a tool containing one or more parts that uses energy to perform an intended action. Machines are usually powered by mechanical, chemical, thermal, or electrical means, and are often motorized. Historically, a power tool also required moving parts to classify as a machine. However, the advent of electronics has led to the development of power tools without moving parts that are considered machines.

A simple machine is a device that simply transforms the direction or magnitude of a force, but a large number of more complex machines exist. Examples include vehicles, electronic systems, molecular machines, computers, television, and radio.

Etymology

The word machine derives from the Latin word machina, which in turn derives from the Greek (Doric μαχανά makhana, Ionic μηχανή mekhane "contrivance, machine, engine", a derivation from μῆχος mekhos "means, expedient, remedy").

A wider meaning of "fabric, structure" is found in classical Latin, but not in Greek usage.

This meaning is found in late medieval French, and is adopted from the French into English in the mid-16th century.

Artension

Artension was a North American neo-classical progressive metal band, founded in 1993 by keyboardist Vitalij Kuprij.

History

It was sometime in '92/'93, when Vitalij Kuprij, who was studying classical music in Switzerland at that time, met Roger Staffelbach, a Swiss guitarist who was also studying at the Jazz School in Lucerne.

They soon founded their band "Atlantis Rising", which played several instrumental gigs in Switzerland. After having recorded some demos, they got in touch with Mike Varney of Shrapnel Records, who showed great interest in the band but suggested to add some vocal lines to their songs.

Vitalij had already known stunning drummer Mike Terrana from one of Yngwie Malmsteen's tours. His friend, bassist Kevin Chown, also joined the band and enriched their sound with solid experience and great musicianship, and Artension was born.

Mike Varney introduced Vitalij and Roger to several musicians, one of them being John West, whose soaring vocals, along with Vitalij's and Roger's lightning-fast solos, became the trademark for Artension's neo-classical and aggressive music.

Machine (mechanical)

Machines employ power to achieve desired forces and movement (motion). A machine has a power source and actuators that generate forces and movement, and a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. Modern machines often include computers and sensors that monitor performance and plan movement, and are called mechanical systems.

The meaning of the word "machine" is traced by the Oxford English Dictionary to an independently functioning structure and by Merriam-Webster Dictionary to something that has been constructed. This includes human design into the meaning of machine.

The adjective "mechanical" refers to skill in the practical application of an art or science, as well as relating to or caused by movement, physical forces, properties or agents such as is dealt with by mechanics. Similarly Merriam-Webster Dictionary defines "mechanical" as relating to machinery or tools.

Power flow through a machine provides a way to understand the performance of devices ranging from levers and gear trains to automobiles and robotic systems. The German mechanician Franz Reuleaux wrote "a machine is a combination of resistant bodies so arranged that by their means the mechanical forces of nature can be compelled to do work accompanied by certain determinate motion." Notice that forces and motion combine to define power.

Buck (crater)

Buck is a crater in the Navka region of Venus. It has the terraced walls, flat radar-dark floor, and central peak that are characteristic of craters classified as 'complex'. The central peak on its floor is unusually large. Flow-like deposits extend beyond the limits of the coarser rim deposits on its west and southwest. Like about half of the craters mapped by Magellan to date, it is surrounded by a local, radar-dark halo.

The Call of the Wild

The Call of the Wild is a short adventure novel by Jack London published in 1903 and set in Yukon, Canada during the 1890s Klondike Gold Rush, when strong sled dogs were in high demand. The central character of the novel is a dog named Buck. The story opens at a ranch in the Santa Clara Valley of California when Buck is stolen from his home and sold into service as a sled dog in Alaska. He progressively reverts to a wild state in the harsh climate, where he is forced to fight to dominate other dogs. By the end, he sheds the veneer of civilization and relies on primordial instinct and learned experience to emerge as a leader in the wild.

London spent almost a year in the Yukon collecting material for the book. The story was serialized in the Saturday Evening Post in the summer of 1903; it was published a month later in book form. The book’s great popularity and success made a reputation for London. Much of its appeal derives from its simplicity as a tale of survival. As early as 1923, the story was adapted to film, and it has since seen several more cinematic adaptations.

Buck (film)

Buck is a 2011 American documentary film directed by Cindy Meehl. The film focuses on the life, career, and philosophy of the real-life "horse whisperer" Buck Brannaman.

Synopsis

Buck explores the life of Buck Brannaman from his childhood living with an abusive father to his successful approach to handling and training horses. Brannaman worked on the Robert Redford film The Horse Whisperer as the lead equine consultant. He teaches people to communicate with their horses through leadership and sensitivity, not punishment.

The documentary follows Brannaman to several stops on his normal, 40-week-per-year circuit of ranches where he gives clinics on "natural horsemanship". He spends most of the year on the road, apart from his wife and daughters. Along the way, viewers learn about his childhood including his celebrity as a child performer of rope tricks, the physical abuse that he and his brother endured at the hands of their father, how a football coach helped to free him from his father after seeing welts on Buck's back and legs, and life with the Shirleys, his foster parents.
