A pseudoscope [soo-duh-skohp] (‘false view’) is a binocular optical instrument that reverses depth perception. It is used to study human stereoscopic perception. Objects viewed through it appear inside out, for example: a box on a floor would appear as a box shaped hole in the floor. It typically uses sets of optical prisms, or periscopically arranged mirrors to swap the view of the left eye with that of the right eye.
In the 1800s Victorian scientist Charles Wheatstone coined the name and used the device to explore his theory of stereo vision. Switching the two pictures in a standard stereoscope changes all the elevated parts into depressions, and vice versa.

The slit-scan photography technique is a photographic and cinematographic process where a moveable slide, into which a slit has been cut, is inserted between the camera and the subject to be photographed. Originally used in static photography to achieve blurriness or deformity, the slit-scan technique was perfected for the creation of spectacular animations. It enables the cinematographer to create a psychedelic flow of colors.
Though this type of effect is now often created through computer animation, slit-scan is a mechanical technique. It was adapted for film by Douglas Trumbull during the production of Stanley Kubrick’s ‘2001: A Space Odyssey’ and used extensively in the ‘stargate’ sequence. It requires an imposing machine, capable of moving the camera and its support.

A Fire Upon the Deep is a 1992 science fiction novel by Vernor Vinge. It is a space opera involving superhuman intelligences, aliens, faster-than-light warfare, love, betrayal, genocide, and a galactic Usenet (an early Internet discussion system).
The story is set in Vinge’s ‘Zones of Thought’ in which the results of technological singularities (the achievement of greater-than-human intelligence) are spread out in a predicable pattern: In the ‘Unthinking Depths’ near the core of the galaxy, no intelligence is possible; in the ‘Slow Zone,’ where Earth is, general relativity applies (i.e. faster-than-light travel is impossible); the ‘Beyond’ allows faster-than-light travel and antigravity, and in the ‘Transcend,’ mysterious god-like entities roam the cosmos. Thus, as you head out of the Milky Way, you see the same progression of advancing technologies in other galaxies.

Josef Albers (1888 – 1976) was a German-born American artist and educator whose work formed the basis of some of the most influential and far-reaching art education programs of the 20th century. Accomplished as a designer, photographer, typographer, printmaker, and poet, Albers is best remembered for his work as an abstract painter and theorist. He favored a very disciplined approach to composition. Most famous of all are the hundreds of paintings and prints that make up the series ‘Homage to the Square.’ In this rigorous series, begun in 1949, Albers explored chromatic interactions with nested squares.
Painting usually on Masonite (an engineered wood product), he used a palette knife with oil colors and often recorded colors used on the back of his works. Albers’s work represents a transition between traditional European art and the new American art. It incorporated European influences from the constructivists and the Bauhaus movement, and its intensity and smallness of scale were typically European. But his influence fell heavily on American artists of the late 1950s and the 1960s. ‘Hard-edge’ abstract painters drew on his use of patterns and intense colors, while Op artists and conceptual artists further explored his interest in perception.

Richard Anuszkiewicz [an-uhskey-vich] (b. 1930) is an American painter, printmaker, and sculptor. He trained at the Cleveland Institute of Art, and with German artist Josef Albers, at the Yale University School of Art and Architecture where he earned his Masters of Fine Arts. He was one of the founders and foremost exponents of Op Art, a movement during the late 1960s and early 1970s which explore optical illusions. Victor Vasarely in France and Bridget Riley in England were his primary international counterparts.
In 1964, ‘Life’ magazine called him ‘one of the new wizards of Op.’ More recently, while reflecting on a New York City gallery show of Anuszkiewicz’s from 2000, the ‘New York Times’ art critic Holland Cotter described Anuszkiewicz’s paintings by stating, ‘The drama — and that feels like the right word — is in the subtle chemistry of complementary colors, which makes the geometry glow as if light were leaking out from behind it.’

There are many theories of humor which attempt to explain what humor is, what social function it serves, and what would be considered humorous. It would be very difficult to explain humor to a hypothetical person who did not have a sense of humor already. In fact, to such a person humor would appear to be quite strange if not outright irrational behavior.
Among the prevailing types of theories that attempt to account for the existence of humor there are: psychological theories (the vast majority of which consider humor to be very healthy behavior); spiritual theories (which may consider humor to be a ‘gift from God’). There are also theories that consider humor to be an unexplainable mystery, very much like a mystical experience. Although various classical theories of humor and laughter may be found, in contemporary academic literature three theories of humor appear repeatedly: relief theory, superiority theory, and incongruity theory.

Nervous laughter is laughter evoked from an audience’s expression of embarrassment, alarm, discomfort, or confusion, rather than amusement. Nervous laughter is usually less robust in expression than ‘a good belly laugh,’ and may be combined with confused glances or awkward silence on the part of others in the audience. Nervous laughter is considered analogous to a courtesy laugh, which may be rendered by more of a conscious effort in an attempt to move a situation along more quickly, especially when the comedian is pausing for laughter.
Nervous laughter is a physical reaction to stress, tension, confusion, or anxiety – just like sweaty palms or an elevated heart-rate. It’s not a conscious decision; it has nothing to do with one’s sense of humor and can occur at the unfunniest of times. Neuroscientist Vilayanur Ramachandran states ‘We have nervous laughter because we want to make ourselves think what horrible thing we encountered isn’t really as horrible as it appears, something we want to believe.’ Those are the most embarrassing times, too, naturally.

Laughter is an audible expression or appearance of excitement, an inward feeling of joy. It may ensue from jokes, tickling, and other stimuli. It is associated with a number of positive emotional states, such as joy, mirth, happiness, and relief. However on some occasions it may express other emotions, such as embarrassment, contrition, or confusion.
A nervous laugh or courtesy laugh is rendered by a more conscious effort, in an attempt to move a situation along more quickly. Laughter is a part of human behavior regulated by the brain, helping humans clarify their intentions in social interaction and providing an emotional context to conversations.

Laughter in animals other than humans describes animal behavior which resembles human laughter. Self awareness is conscious concomitant of the physiological processes involving laughter or smiling reflex (response) and its grades, degrees, or spectrum varies according to phylogenetic development, with no clear cut demarcation. The emotional ingredients (such as contempt, hatred, ridicule, sarcasm, love, amusement etc.) are variable and involve different neurophysiological and physiological processes.
Chimpanzees, gorillas, bonobos and orangutans show laughter-like vocalizations in response to physical contact, such as wrestling, play chasing, or tickling. This is documented in wild and captive chimpanzees. Chimpanzee laughter is not readily recognizable to humans as such, because it is generated by alternating inhalations and exhalations that sound more like panting or screeching. The differences between chimpanzee and human laughter may be the result of adaptations that have evolved to enable human speech. It is hard to tell, though, whether or not the chimpanzee is expressing joy.

A smile is a facial expression formed by flexing the muscles near both ends of the mouth. The smile can also be found around the eyes (‘Duchenne Smiling’). Among humans, it is an expression denoting pleasure, joy, happiness, or amusement, but can also be an involuntary expression of anxiety, in which case it is known as a grimace. Smiling is something that is understood by everyone despite culture, race, or religion; it is internationally known.
Cross-cultural studies have shown that smiling is a means of communicating emotions throughout the world. But there are large differences between different cultures. A smile can also be spontaneous or artificial. Many biologists think the smile originated as a sign of fear. Primalogist Signe Preuschoft traces the smile back over 30 million years of evolution to a ‘fear grin’ stemming from monkeys and apes who often used barely clenched teeth to portray to predators that they were harmless. Biologists believe the smile has evolved differently among species and especially among humans.

A cultural universal is an element, pattern, trait, or institution that is common to all human cultures worldwide. Taken together, the whole body of cultural universals is known as the human condition. Evolutionary psychologists hold that behaviors or traits that occur universally in all cultures are good candidates for evolutionary adaptations. Some anthropological and sociological theorists that take a cultural relativist perspective may deny the existence of cultural universals: the extent to which these universals are ‘cultural’ in the narrow sense, or in fact biologically inherited behavior is an issue of ‘nature versus nurture.’
Anthropological universals include: Language and Cognition (e.g. language employed to manipulate others, language employed to misinform or mislead, binary cognitive distinctions, color terms for black and white, figurative speech and metaphors, taboo utterances, and units of time); Society (e.g. personal names, families, laws, moral sentiments, promises, prestige inequalities, statuses and roles, leaders, property, gender roles, male dominated public/political realm, males more aggressive and more prone to violence and theft, marriage, incest avoidance, rape prohibitions, etiquette, inheritance rules, gift giving, redress of wrongs, sexual jealousy, shame, territoriality, visiting, and trade); Myth and Ritual (e.g. magical thinking, dream interpretation, proverbs, poetry, medicine, rites of passage, music, dance, play, toys, mourning, feasting, body adornment, and hairstyles); and Technology (e.g. shelter, control of fire, tools, weapons, containers, cooking, levers, tying and weaving).

The evolutionary psychology of religion is the study of religious belief using evolutionary psychology principles. As with all other organs and organ functions, the brain and cognition’s functional structure have been argued to have a genetic basis, and are therefore subject to the effects of natural selection and evolution. Like other organs and tissues, this functional structure should be universally shared amongst humans and should solve important problems of survival and reproduction. Evolutionary psychologists seek to understand cognitive processes, religion in this case, by understanding the survival and reproductive functions they might serve.
There is general agreement among scientists that a propensity to engage in religious behavior evolved early in human history. However, there is disagreement on the exact mechanisms that drove the evolution of the religious mind. There are two schools of thought. One is that religion itself evolved due to natural selection and is an adaptation, in which case religion conferred some sort of evolutionary advantage. Alternatively, religious beliefs and behaviors may have emerged as by-products of other adaptive traits without initially being selected for because of their own benefits (called spandrels).
