[Middle English, from Old English sceaduwe, oblique case of sceadu, shade, shadow.]
shadower shad'ow·er n.WORD HISTORY Shade and shadow are not only related in meaning; historically they are the same word. In Old English, the ancestor of Modern English spoken a thousand years ago, nouns were inflected; that is, they had different forms depending on how they were used in a sentence. One of the inflected forms of the Old English noun sceadu, translatable as either "shade" or "shadow," was sceaduwe; this form was used when the word was preceded by a preposition (as in in sceaduwe, "in the shade, in shadow"). As time went on these two forms of the same word were interpreted as two separate words. The same thing happened to other Old English words, too: our mead and meadow come from two different case-forms of the same Old English word for "meadow."
A region of darkness caused by the presence of an opaque object interposed between such a region and a source of light. A shadow can be totally dark only in that part called the umbra, in which all parts of the source are screened off. With a point source, the entire shadow consists of an umbra, since there can be no region in which only part of the source is eclipsed. If the source has an appreciable extent, however, there exists a transition surrounding the umbra, called the penumbra, which is illuminated by only part of the source. Depending on what fraction of the source is exposed, the illumination in the penumbra varies from zero at the edge of the full shadow to the maximum where the entire source is exposed. The edge of the umbra is not perfectly sharp, even with an ideal point source, because of the wave character of light. See also Diffraction; Eclipse.

In Carl Gustav Jung's analytical psychology, the shadow as a concept comprises everything the conscious personality experiences as negative. In dreams and fantasies the shadow appears with the characteristics of a personality of the same sex as the ego, but in a very different configuration. It is presented as the eternal antagonist of an individual or group, or the dark brother within, who always accompanies one, the way Mephistopheles accompanied Goethe's Faust.
The role of the shadow within is sometimes hidden, and sometimes rejected or repressed, by the conscious ego. In the latter case it is pushed into the unconscious, where, because of its energy, it acts as a complex. People can, for example, be fully aware that they are avaricious, greedy, or aggressive and still manage to hide these truths from others beneath the mask of the persona. But they can also repress those characteristics. Then they are no longer conscious of them at all, and their moral ego is reestablished.
The shadow in everyone varies considerably depending on the guidelines in force within the family, the community, and the culture in which they grow up. Moreover, the shadow is not only made up of aspects of personality experienced as disagreeable or negative, but it can also have a positive side.
When the shadow is not integrated into the conscious personality and remains unconscious, it can manifest itself in two different forms. On the one hand, it can project itself onto another person in one's immediate or distant circle, leading to serious conflicts among siblings, couples, or colleagues that have a tendency to recur and lead to lasting misunderstandings. On the other hand, it can also cause deflation, so that those involved find themselves subjugated and thus inferior, bad, or clumsy. In fact, the shadow corresponds to what one does not want to become but still is, within the self. It is even something necessary, for just as a painting needs shadow to give it life and depth, each human needs a shadow—as illustrated by Peter Schlemihl de Chamisso (1824)—to become a true human being with all the genuine weaknesses and defects, qualities which can even make them likeable.
Jung developed and enriched the concept of the shadow throughout the 1930s, when he began studying closely alchemical literature and iconography in relation to his experience and conception of the process of individuation. He compared the "black work" of the alchemists (the nigredo) with the often highly critical involvement experienced by the ego, until it accepts the new equilibrium brought about by the creation of the self.
In the work he did after World War II, Jung developed the distinction between the personal shadow and the collective shadow, emphasizing the fact that while recognition and analysis of the shadow lead to a confrontation with the drives and the most intimate representations, they also lead to a confrontation with the collective unconscious. It is this that gives rise to projections of the shadow onto other cultures, other peoples, and other races—something that occurred during the twentieth century to an alarming extent.

—HANS DIECKMANN
The process of creating values for variables that don't rely purely on market value. Some of these variables have a market value in the present but have indeterminable future market values due to variable conditions.
Shadowing is used as in cost-benefit analysis, which allows analysts to evaluate the future comprehensive value of a variable in any number of projected conditions.
Investopedia Says:
Shadowing calculates a shadow price for the variable rather than relying solely on market price, which is how the value of economic variables tends to be measured. This hypothetical shadow price is calculated largely based on the opportunity costs and benefits of the projected scenario. By taking into account the potential costs and benefits of any given scenario, the value of the variable then reflects those circumstances in its determined worth.

A shadow may represent the hidden aspects of the self. The dreamer often does not accept these parts of his or her personality and they are projected upon others until the dreamer can accept them and incorporate them into his or her psyche.

A shadow is an area where direct light from a light source cannot reach due to obstruction by an object. It occupies all of the space behind an opaque object with light in front of it. The cross section of a shadow is a two-dimensional silhouette, or reverse projection of the object blocking the light. The sun causes many objects to have shadows and at certain times of the day, when the sun is at certain heights, the lengths of shadows change.
An astronomical object casts human-visible shadows when its apparent magnitude is equal or lower than −4.[1] Currently the only astronomical objects able to produce visible shadows on Earth are the sun, the moon and, in the right conditions, the planet Venus.

Shadow length when caused by the sun changes dramatically throughout the day. The length of a shadow cast on the ground is proportional to the cotangent of the sun's elevation angle—its angle θ relative to the horizon. Near sunrise and sunset, when θ = 0° and cot(θ) is infinite, shadows can be extremely long. If the sun passes directly overhead, then θ = 90°, cot(θ)=0, and shadows are cast directly underneath objects.
For a non-point source of light, the shadow is divided into the umbra and penumbra. The wider the light source, the more blurred the shadow. If two penumbras overlap, the shadows appear to attract and merge. This is known as the Shadow Blister Effect.
If there are multiple light sources there are multiple shadows, with overlapping parts darker, or a combination of colors. For a person or object touching the surface, like a person standing on the ground, or a pole in the ground, these converge at the point of touch.
The farther the distance from the object blocking the light to the surface of projection, the larger the silhouette (they are considered proportional). Also, if the object is moving, the shadow cast by the object will project an image with dimensions (length) expanding proportionally faster than the object's own rate of movement. The increase of size and movement is also true if the distance between the object of interference and the light source are closer. This, however, does not mean the shadow may move faster than light, even when projected at vast distances, such as light years. The loss of light, which projects the shadow, will move towards the surface of projection at light speed.
The misconception is that the edge of a shadow "moves" along a wall, when in actuality the increase of a shadow's length is part of a new projection, which will propagate at the speed of light from the object of interference.
Since there is no actual communication between points in a shadow (except for reflection or interference of light, at the speed of light), a shadow that projects over a surface of large distances (light years) cannot give information between those distances with the shadow's edge.[2]
In photography, which is essentially recording patterns of light, shade, and colour, "highlights" and "shadows" are the brightest and darkest parts of a scene or image. Photographic exposure must be adjusted (unless special effects are wanted) to allow the film or sensor, which has limited dynamic range, to record detail in the highlights without them being washed out, and in the shadows without their becoming undifferentiated black areas.
Fog shadows look odd since humans are not used to seeing shadows in three dimensions. The thin fog is just dense enough to be illuminated by the light that passes through the gaps in a structure or in a tree. As a result, the path of an object shadow through the "fog" appears darkened. In a sense, these shadow lanes are similar to crepuscular rays, which are caused by cloud shadows, but here, they are caused by the shadows of solid objects.
A shadow cast by the Earth on the Moon is a lunar eclipse. Conversely, a shadow cast by the Moon on the Earth is a solar eclipse.
On satellite imagery and aerial photographs, taken vertically, tall buildings can be recognized as such by their long shadows (if the photographs are not taken in the tropics around noon), while these also show more of the shape of these buildings.
A shadow shows, apart from distortion, the same image as the silhouette when looking at the object from the sun-side, hence the mirror image of the silhouette seen from the other side (see picture).
Shadow as a term is often used for any occlusion, not just those with respect to light. For example, a rain shadow is a dry area, which, with respect to the prevailing wind direction, is beyond a mountain range; the range is "blocking" water from crossing the area. An acoustic shadow can be created by terrain as well that will leave spots that can't easily hear sounds from a distance.
Sciophobia, or sciaphobia, is the fear of shadows.
An unattended shadow or shade was thought by some cultures to be similar to that of a ghost.
It is also believed as an alternative construct that shadows are in fact a representation of God's presence around an object; like a halo. Early eastern beliefs also play to this theory.
In heraldry, when a charge is supposedly shown in shadow (the appearance is of the charge merely being outlined in a neutral tint rather than being of one or more tinctures different from the field on which it is placed), it is called umbra-ted. Supposedly only a limited number of specific charges can be so depicted. Shadows can be colored by a colored transparent source of the shadow.
Speculative fiction occasionally features entities somehow made of shadow. Such beings are almost invariably evil.
