The self is an individual person as the object of his or her own reflective consciousness. The self has been studied extensively by philosophers and psychologists and is central to many world religions.
The philosophy of self seeks to describe essential qualities that constitute a person's uniqueness or essential being. There have been various approaches to defining these qualities. The self can be considered that being which is the source of consciousness; the agent responsible for an individual's thoughts and actions; and/or the substantial nature of a person which endures and unifies consciousness over time.
The philosophy of a disordered self, such as in schizophrenia, is described in terms of what the psychiatrist understands are actual events in terms of neuron excitation but are delusions nonetheless, and the schizo-affective or schizophrenic person also believes are actual events in terms of essential being. PET scans have shown that auditory stimulation relates to certain areas of the brain and imagined similar events occur in adjacent areas but hallucinations occur in the same areas. In such cases, external influences may be the source of consciousness and the person may or may not be responsible for "sharing" in the mind's process; and/or the events which occur, such as visions and auditory stimuli, may endure and be repeated often over hours, days, months or years -- and the afflicted person may believe themselves to be in a state of rapture and/or possession, which their artistic expression may tend to confirm. Whether art has moral responsibility is difficult to relate to the idea of a unique source of consciousness and rapid thinking may lead to an insubstantial nature of the enduring person's consciousness over time; it can be said in view of these two exigencies that the person is vulnerable.
A coil is a series of loops. A coiled coil is a structure in which the coil itself is in turn also looping.
An electromagnetic coil (or simply a "coil") is formed when a conductor (usually an insulated solid copper wire) is wound around a core or form to create an inductor or electromagnet. One loop of wire is usually referred to as a turn, and a coil consists of one or more turns. For use in an electronic circuit, electrical connection terminals called taps are often connected to a coil. Coils are often coated with varnish or wrapped with insulating tape to provide additional insulation and secure them in place. A completed coil assembly with taps is often called a winding. A transformer is an electromagnetic device that has a primary winding and a secondary winding that transfers energy from one electrical circuit to another by inductive coupling without moving parts. The term tickler coil usually refers to a feedback coil, which is often the third coil placed in relation to a primary coil and secondary coil. A coil tap is a wiring feature found on some electrical transformers, inductors and coil pickups, all of which are sets of wire coils. The coil tap(s) are points in a wire coil where a conductive patch has been exposed (usually on a loop of wire that extends out of the main coil body). As self induction is larger for larger coil diameter the current in a thick wire tries to flow on the inside. The ideal use of copper is achieved by foils. Sometimes this means that a spiral is a better alternative. Multilayer coils have the problem of interlayer capacitance, so when multiple layers are needed the shape needs to be radically changed to a short coil with many layers so that the voltage between consecutive layers is smaller (making them more spiral like).
