Abhisheka Abhisheka as a ritual Abhisheka, also called Abhishekam, is conducted by priests, by pouring libations on the image of the deity being worshipped, amidst the chanting of mantras. Usually, offerings such as milk, yogurt, ghee, honey, Panchaamrutam, sesame oil, rosewater, sandalwood paste may be poured among other offerings depending on the type of abhishekam being performed. This ritual is routinely performed in some Hindu and Jain temples. Hinduism Abhisheka is the name given to a late Vedic rite of anointing government officials, particularly heads of state, at the time of their taking power or to mark a signal achievement.

The eyes have it: Seeing ultraviolet, exploring color One of the enduring commonalities across most human societies is the belief that our eyes are a window into the immutable truth of the universe. Eyewitnesses are accorded special status in trials, despite repeated studies demonstrating how fallible such on-the-scene reports can be. The idea that sight conveys reality is enshrined in everything from dusty myths and sacred texts to modern-day cop shows. As a result, it’s equal parts unsettling and interesting when we get a glimpse of how fluid our shared capability of vision can be. Former Air Force Officer and engineer Alek Komar has spent a considerable amount of time detailing how his color vision changed following major cataract surgery. The image above is Komar’s simulation of what UV light looks like to him on surfaces where the rest of us just see black. This image shows a Rudbeckia flower, first in visible light, second with simulated tetrachromatic vision as butterflies and bees would see it.
Hue An image with the hues cyclically shifted in HSL space The hues in this image of a Painted Bunting are cyclically rotated over time. Computing hue In opponent color spaces in which two of the axes are perceptually orthogonal to lightness, such as the CIE 1976 (L*, a*, b*) (CIELAB) and 1976 (L*, u*, v*) (CIELUV) color spaces, hue may be computed together with chroma by converting these coordinates from rectangular form to polar form. Hue is the angular component of the polar representation, while chroma is the radial component. Specifically, in CIELAB: while, analogously, in CIELUV: Where, atan2 is a two-argument inverse tangent. Computing hue from RGB Preucil describes a color hexagon, similar to a trilinear plot described by Evans, Hanson, and Brewer, which may be used to compute hue from RGB. Equivalently, one may solve: HSV color space as a conical object Note that in each case the formula contains the fraction Specialized hues Usage in art Hue difference: or ?
Logos in Lego Town I love the list of 'fictional universes' on Wikipedia. It contains everything from The Simpsons to Star Trek to The Wizarding World of Harry Potter. The Fictional Universes database on Freebase is even better, as it contains thousands of details about the universes, such as species, objects, and even ethnicities. However, one universe neither site coves is Lego. Anyway, I thought I'd start to address this lack of understanding about the Lego Universe with a look at some of the companies and organisations that serve the Lego urban-dwelling minifigs. We'll start with the law-enforcement service, the police department. The fire service, by contrast, has retained a much more unified identity, with a logo consisting of three flames elegantly arranged in a fan. The ambulance and hospital service initially used the Red Cross logo, however in more recent history, the hospitals and ambulances have adopted a fetching logo featuring a white Rod of Asclepius on a blue six-pointed star.
What if our eyes could see a wider gamut of the electromagnetic spectrum? | Gearside Creative Have you ever wondered what the world would look like if our eyes could see infrared and ultraviolet light? What if the visual spectrum of light was wider? What if we could see the entire electromagnetic spectrum? Currently, we know that blue plus yellow equals green, but would that change if our eyes could detect more wavelengths of color? Technically- no, but that doesn’t mean that the world we see would stay the same! Humans are trichromats, meaning we have cones sensitive to red, green, and blue light. On the other end of the spectrum is infrared light, which is an interesting region since our bodies actually emit light of this frequency. If you could see x-rays, you would no longer be able to sleep without an iron eyemask since x-rays can so easily penetrate our skin, so you would not be able to turn off your x-ray vision. Our sky actually glows with microwaves. Since gamma rays are not as common as other frequencies in the spectrum, our eyes would not see them from many sources.
Roue des couleurs La couleur est à la fois un phénomène psychophysiologique et un phénomène psychophysique. La perception des couleurs dépend d'une part de la physique de la lumière, considérée comme de l'énergie électromagnétique, et d'autre part de l'interprétation des phénomènes résultants par le système visuel constitué par ton oeil et ton cerveau. Comme tu le sais, le système visuel humain interprète l'énergie électromagnétique comme de la lumière visible pour des longueurs d'onde comprises entre 400 et 700 nm. Lorsque la lumière percue contient toutes les longueurs d'ondes en proportions approximativement égales, la source de lumière ou l'objet qui la réfléchit sont dits achromatiques. Un telle source achromatique apparaît blanche. Lorsque la lumière perçue contient plusieurs longueurs d'ondes en proportions arbitrairement inégales, sa couleur est dite chromatique. Ce sont les les longueurs d'onde de la lumière réfléchie ou transmise qui déterminent la couleur des objets.
Are you stuck in a state of perpetual adolescence around your family? Yet, why do otherwise respectful, generous adults sometimes switch into some form of moronic adolescence when around our other family members? It is partly due to the fact that we actually have never had adult relationships with these people we call 'family'. My sister, for example, left for university when I was only 14 years old. We never lived with each other after this time and we only saw each other at family gatherings. With her being in the military, her attendance at these gatherings was somewhat sporadic and thus, we really never got to know each other as adult women and continued to relate to each other as teenage rivals. The same can be said for relationships with parents. Arguably, some parents perpetuate a prolonged youth in their adult children. Granted there are benefits to playing up our childhood roles with our families (e.g., we get our clothes washed and folded for free).
Faster-than-light Faster-than-light (also superluminal or FTL) communications and travel refer to the propagation of information or matter faster than the speed of light. Under the special theory of relativity, a particle (that has rest mass) with subluminal velocity needs infinite energy to accelerate to the speed of light, although special relativity does not forbid the existence of particles that travel faster than light at all times (tachyons). On the other hand, what some physicists refer to as "apparent" or "effective" FTL depends on the hypothesis that unusually distorted regions of spacetime might permit matter to reach distant locations in less time than light could in normal or undistorted spacetime. Although according to current theories matter is still required to travel subluminally with respect to the locally distorted spacetime region, apparent FTL is not excluded by general relativity.

Diagramme CIE A partir des 3 valeurs (X, Y, Z) on peut définir les valeurs (x, y, z) de la chromaticité CIE (Commission Internationale de l'Éclairage) au moyen des relations: avec par définition x + y + z = 1. Lorsque l'on projette le triangle XYZ sur un plan dans le but de former un diagramme bidimensionnel, les chromaticités choisies sont par convention x et y. On obtient un diagramme CIE en forme d'aile qui représente le lieu de toutes les longueurs d'ondes visibles: Les couleurs pures ou totalement saturées se trouvent sur le contour du spectre et sont 100% pures. Le nom des couleurs et leurs positions sur le diagramme CIE sont données ci-après: La signification est abbréviations est la suivante: Rs = Rose R = Rouge B = Bleu V = Vert J = Jaune O = Orange P = Pourpre. On peut situer le lieu du corps noir dans la zone centrale, appelée "source": La courbe représente la couleur d'un corps noir théorique lorsque la température s'élève de 1000K à l'infini.
Defence mechanism A defence mechanism is a coping technique that reduces anxiety arising from unacceptable or potentially harmful impulses. Defence mechanisms are unconscious and are not to be confused with conscious coping strategies. Sigmund Freud was one of the first proponents of this construct. Healthy persons normally use different defences throughout life. An ego defence mechanism becomes pathological only when its persistent use leads to maladaptive behaviour such that the physical or mental health of the individual is adversely affected. The purpose of ego defence mechanisms is to protect the mind/self/ego from anxiety and/or social sanctions and/or to provide a refuge from a situation with which one cannot currently cope. One resource used to evaluate these mechanisms is the Defense Style Questionnaire (DSQ-40). Structural model: Id, ego, and superego Freud believed that conflicts between these two structures resulted in conflicts associated with psychosexual stages.
Someday you may ditch your two-factor authenticator for an electronic tattoo Electronic “tattoos” and pills that turn your body into an authenticator are two next-steps in password protection that Motorola is working on, as described at a session Wednesday at AllThingsD’s D11 conference. Regina Dugan, senior vice president of the Advanced Technology and Projects group at Motorola Mobility, showed off two “wearable computing” oriented methods that remove the security tokens from the two-factor equation. The electronic tattoos described must strike a balance between the “mechanical mismatch” of hard, rigid machines and soft, pliable humans, Dugan said. The “tattoo” Dugan wore, which appeared to be more like a sticker on her left wrist, uses “islands of high-performance silicon connected by accordion-like structures” that allow the tattoo to flex and move with her skin to stay on and remain functional. Presumably, the silicon and wires would eventually be embedded into the skin to make the user a proper bionic human.
