Pupil
The pupil is a black hole located in the center of the iris of the eye that allows light to strike the retina.Cassin, B. and Solomon, S. (1990) ''Dictionary of Eye Terminology''. Gainesville, Florida: Triad Publishing Company. It appears black because light rays entering the pupil are either absorbed by the tissues inside the eye directly, or absorbed after diffuse reflections within the eye that mostly miss exiting the narrow pupil. The term "pupil" was coined by Gerard of Cremona. In humans, the pupil is round, but its shape varies between species; some cats, reptiles, and foxes have vertical slit pupils, goats have horizontally oriented pupils, and some catfish have annular types. In optical terms, the anatomical pupil is the eye's aperture and the iris is the aperture stop. The image of the pupil as seen from outside the eye is the entrance pupil, which does not exactly correspond to the location and size of the physical pupil because it is magnified by the cornea.

Lamp (electrical Component)
An electric light, lamp, or light bulb is an electrical component that produces light. It is the most common form of artificial lighting. Lamps usually have a base made of ceramic, metal, glass, or plastic, which secures the lamp in the socket of a light fixture, which is often called a "lamp" as well. The electrical connection to the socket may be made with a screw-thread base, two metal pins, two metal caps or a Bayonet mount, bayonet cap. The three main categories of electric lights are incandescent lamps, which produce light by a Incandescent light bulb#Filament, filament heated white-hot by electric current, gas-discharge lamps, which produce light by means of an electric arc through a gas, such as fluorescent lamps, and LED lamps, which produce light by a flow of electrons across a band gap in a semiconductor. Before electric lighting became common in the early 20th century, people used candles, gas lighting, gas lights, oil lamps, and fires. Vasily Vladimirovich Petr ...

Milbourne Christopher
Milbourne Christopher (23 March 1914 – 17 June 1984) was a prominent American illusionist, magic historian, and author. President of the Society of American Magicians, an honorary vice-president to The Magic Circle, and one of the founding members of the Committee for Skeptical Inquiry, Christopher wrote a number of books, including a biography of Harry Houdini titled ''Houdini: The Untold Story,'' a chronicle of his own craft titled ''The Illustrated History Of Magic,'' and thousands of essays relating to magic and mentalism. Debunking work Christopher regarded those individuals who claimed extrasensory perception or psychic powers to be actually using magic trickery. He wrote three book-length exposés regarding those he said were false seers or psychics: ''ESP, Seers & Psychics;'' ''Mediums, Mystics & The Occult;'' and ''Search For The Soul.'' In the latter book he found no evidence for the existence of the soul. Skeptical investigator Joe Nickell who was influenced by C ...

Parapsychology
Parapsychology is the study of alleged psychic phenomena (extrasensory perception, telepathy, precognition, clairvoyance, psychokinesis (also called telekinesis), and psychometry) and other paranormal claims, for example, those related to near-death experiences, synchronicity, apparitional experiences, etc. Criticized as being a pseudoscience, the majority of mainstream scientists reject it. Parapsychology has also been criticised by mainstream critics for many of its practitioners claiming that their studies are plausible in spite of there being no convincing evidence for the existence of any psychic phenomena after more than a century of research. Parapsychology research rarely appears in mainstream scientific journals; instead, most papers about parapsychology are published in a small number of niche journals. Terminology The term ''parapsychology'' was coined in 1889 by philosopher Max Dessoir as the German . It was adopted by J. B. Rhine in the 1930s as a replacement fo ...
