The Selfie Contraption

A simple machine uses a single applied force to do work against a single load force. Ignoring friction losses, the work done on the load is equal to the work done by the applied force. The machine can increase the amount of the output force, at the cost of a proportional decrease in the distance moved by the load. The ratio of the output to the applied force is called the mechanical advantage. Simple machines are elementary examples of kinematic chains that are used to model mechanical systems ranging from the steam engine to robot manipulators. The bearings that form the fulcrum of a lever and that allow the wheel and axle and pulleys to rotate are examples of a kinematic pair called a hinged joint. Similarly, the flat surface of an inclined plane and wedge are examples of the kinematic pair called a sliding joint. The screw is usually identified as its own kinematic pair called a helical joint. Starting with four types of joints, the revolute joint, sliding joint, cam joint and gear joint, and related connections such as cables and belts, it is possible to understand a machine as an assembly of solid parts that connect these joints. An orthosis is "an externally applied device used to modify the structural and functional characteristics of the neuromuscular and skeletal system". An orthosis may be used to: Control, guide, limit and/or immobilize an extremity, joint or body segment  Restrict movement in a given direction Assist movement generally Reduce weight bearing forces Correct the shape and/or function of the body, to provide easier movement capability or reduce pain Human enhancement (Augment) is "any attempt to temporarily or permanently overcome the current limitations of the human body through natural or artificial means. It is the use of technological means to select or alter human characteristics and capacities, whether or not the alteration results in characteristics and capacities that lie beyond the existing human range." A cyborg (short for "cyberneticorganism") is a being with both organic andbiomechatronicbody parts. The term was coined in 1960 by Manfred Clynes and Nathan S. Kline. It applies to an organism that has restored function or enhanced abilities due to the integration of some artificial component or technology that relies on some sort of feedback. While cyborgs are commonly thought of as mammals, including humans, they might also conceivably be any kind of organism.

A selfie (/sɛlfiː/) is a self-portrait photograph, typically taken with a digital camera or camera phone held in the hand or supported by a selfie stick. Selfies are often shared on social networking services such as Facebook, Instagram and Twitter. They are usually flattering and made to appear casual. "Selfie" typically refers to self-portrait photos taken with the camera held at arm's length or pointed at a mirror, as opposed to those taken by using a self-timer or remote. A selfie stick can be used to position the camera farther away from the subject, allowing the camera to see more around them. Autoethnography is a form of qualitative research in which an author uses self-reflection and writing to explore their personal experience and connect this autobiographical story to wider cultural, political, and social meanings and understandings. Autoethnography is a self-reflective form of writing used across various disciplines such as communication studies, performance studies, education, English literature, anthropology, social work, sociology, history, psychology, marketing, business and educational administration, arts education and phsyiotherapy. Nombrilism is a way of thinking egocentric . It is also a theory that refers to oneself or indirectly to oneself (for example, by focusing it on the social, cultural, ethnic, etc. environment to which one feels bound) by not remaining objective. Taken to the extreme, egocentric vision leads to the solipsism , as suggested by these quotes from the Treasury paradoxes Philippe Boulanger and Alain Cohen ( Belin Editions , 2007): Unus sum and multi in me ( "I am one, but many are in me, " Zeno of Elea ); "One is not alone in one's skin" ( Henri Michaux ); "I want to open the window to see me go through the street" ( Gérard Lenorman ). Egomania is also known as an obsessive preoccupation with one's self and applies to someone who follows their own ungoverned impulses and is possessed by delusions of personal greatness and feels a lack of appreciation. Someone suffering from this extreme egocentric focus is an egomaniac. The condition is psychologically abnormal. The term egomania is often used by laypersons in a pejorative fashion to describe an individual who is intolerably self-centred. The clinical condition that most resembles the popular conception of egomania is narcissistic personality disorder.
