Philosophical Reflections in the Naisadhacarita
Philosophical Reflections in the Naisadhacarita is the doctoral (Ph.D.) thesis of Harekrishna Meher done in Banaras Hindu University in 1981. It discusses philosophical ideas as reflected in the Sanskrit Mahakavya ‘Naisadhacaritam’ authored by the distinguished poet Sriharsa (12th century). This book (ISBN:9788185094212), first published in 1989 by Punthi Pustak Calcutta, is circulated worldwide. Naisadhacarita Mahakavya of poet Sriharsa enjoys a prominent position among the five great epics of Sanskrit literature. Also known as ‘Naishadha’ or ‘Naishadhiya’, this epic contains twenty-two cantos completed with 2827 verses. Its main theme is the story of love between Nala, the King of Nisadha country and Damayanti, the Princess of Vidarbha. The story of Nala and Damayanti is found in the Mahabharata of Vyasa and Kathasaritsagara of Somadeva. The episode of the epic has been taken from the Mahabharata. Poet Sriharsa has remodelled the story and has added the sentiment of love to it.

Spinning Dancer
The Spinning Dancer, also known as the Silhouette Illusion, is a kinetic, bistable, animated optical illusion GIF image showing a silhouette of a pirouetting female dancer. The illusion, created in 2003 by Japanese web designer Nobuyuki Kayahara, involves the apparent direction of motion of the figure. Some observers initially see the figure as spinning clockwise (viewed from above) and some counterclockwise. Additionally, some may see the figure suddenly spin in the opposite direction. The illusion derives from the lack of visual cues for depth. For instance, as the dancer's arms move from viewer's left to right, it is possible to view her arms passing between her body and the viewer (that is, in the foreground of the picture, in which case she would be circling counterclockwise on her right foot) and it is also possible to view her arms as passing behind the dancer's body (that is, in the background of the picture, in which case she is seen circling clockwise on her left foot). When she is facing to the left or to the right, her breasts and ponytail clearly define the direction she is facing, although there is ambiguity in which leg is which. However, as she moves away from facing to the left (or from facing to the right), the dancer can be seen facing in either of two directions. At first, these two directions are fairly close to each other (both left, say, but one facing slightly forward, the other facing slightly backward) but they become further away from each other until we reach a position where her ponytail and breasts are in line with the viewer (so that neither her breasts nor her ponytail are seen so readily). In this position, she could be facing either away from the viewer or towards the viewer, so that the two possible positions are 180 degrees apart. Another interesting aspect of this illusion can be triggered by placing a mirror vertically, besides the image. The natural expectation would be for the normal image and its reflection to spin in opposite directions. This does not necessarily happen, and provides a paradoxical situation where both mirrored dancers spin in the same direction.

Essays (Montaigne) - The Bordeaux Copy
Les Essais (Bordeaux copy) is a 1588 edition of Michel de Montaigne's Essais held by the Bibliothèque municipale de Bordeaux. The book contains about 1300 manuscript corrections and annotations made by Montaigne between the summer of 1588 and the 13 September 1592 (date of his death). This unique document sheds light on the way Montaigne worked and on the genesis of the final edition of Les Essais. Manuscripts by 16th century authors are very rare and this document is exceptional.

Jurimetrics
Jurimetrics is the application of quantitative methods, and often especially probability and statistics, to law. In the United States, the journal Jurimetrics is published by the American Bar Association and Arizona State University. The Journal of Empirical Legal Studies is another publication that emphasizes the statistical analysis of law. The term was coined in 1949 by Lee Loevinger in his article "Jurimetrics: The Next Step Forward". Showing the influence of Oliver Wendell Holmes, Jr., Loevinger quoted Holmes' celebrated phrase that: The first work on this topic is attributed to Nicolaus I Bernoulli in his doctoral dissertation De Usu Artis Conjectandi in Jure, written in 1709.

Causality
Causality is the relationship between causes and effects. While causality is also a topic studied from the perspectives of philosophy and physics, it is operationalized so that causes of an event must be in the past light cone of the event and ultimately reducible to fundamental interactions. Similarly, a cause cannot have an effect outside its future light cone.

Holography and Its Potential
In Camera Lucida, Roland Barthes discusses the capacity of the photographic image to represent “flat death.” Documentation of an event, happening, or time is traditionally reliant on the photographic to determine its ephemeral existence and to secure its legacy within history. The event is date and time stamped by the photographic document, which stands as proof of its taking place. However, this type of document is often unsuitable to capture the real essence and experience of the artwork in situ. The depth and varied nuances of the event go largely unrepresented in this type of record. The two-dimensional photographic document resigns the embodied and three-dimensional experience to a flat death. The hologram, with its spatial and three-dimensional realization of an image, offers a potential solution to this problem. In providing a view of the dexterity and depth of an inert object or human body, it creates a more comprehensive photographic document as an act of legacy. Although this cannot fully account or attest to the experience (as that can only occur through active and present observation), the three-dimensional representation within the hologram allows for greater understanding of ‘being there’ at the time of its happening. The hologram therefore can be suggested to be a more suitable means of documentation for the active and first-hand art experience. However, there are issues concerning how this type of photographic document functions within an art context. Appropriateness and suitability is as open for debate with the hologram as with its two-dimensional counterpart, concerning how it successfully operates as a document. Attitudes to methods necessary for artistic production and holography’s place within the art process can be responsible for this problem. The seductive qualities of holography may be attributable to any failure that ensues, but if used precisely the process can be effective to create a document within an art context. The failures and successes of the hologram to be reliable as a document of experience are discussed in this article, together with a suggestion of how it might undergo a transformation and reactivation. When situated as an integral component within a new artwork the hologram exists both as a document of the past and an experience in the present, and the article will offer an example of how this can occur.

Relations
Relations are ways in which things, the relata, stand to each other. Relations are in many ways similar to properties in that both characterize the things they apply to. Properties are sometimes treated as a special case of relations involving only one relatum. In philosophy (especially metaphysics), theories of relations are typically introduced to account for repetitions of how several things stand to each other.

Trope
Trope denotes figurative and metaphorical language and one which has been used in various technical senses. The term trope derives from the Greek τρόπος (tropos), "a turn, a change", related to the root of the verb τρέπειν (trepein), "to turn, to direct, to alter, to change"; this means that the term is used metaphorically to denote, among other things, metaphorical language. The term is also used in technical senses, which do not always correspond to its linguistic origin. Its meaning has to be judged from the context, some of which are given below.

Artists and Technologists Creating New-Media-Art-Works
       The deeper the combination of art and technology, the more extensive the cooperation between artists and technologists. In many cases, the creation of New Media Art requires the cooperation of artists and technologists. However, since New Media Art is an emerging art form, the process of cocreating New Media Art between the two is at the exploration stage. Especially in areas with underdeveloped New Media Art and underdeveloped technology, there exist many problems in the cooperation between the two, such as a lack of complete understanding of the factors involved in the cooperation process and a lack of reasonable planning for the cooperation process.

Relational Approach to Quantum Physics
The relational approach to quantum physics is an alternative approach to and interpretation of quantum mechanics. It asserts that the physical world can only be studied accurately in terms of relationships between systems, as all experimentally verifiable facts about the world result explicitly from interactions (such as the interaction between a light field and a detector). According to the relational approach, the assumption that objects possess absolute properties (such as an absolute particle, independent of any detection frame) inevitably leads to ambiguities and paradoxes when these objects are studied closely. The approach was adopted, in a time span of 1992-1996, by Q. Zheng, S. Hughes, and T. Kobayashi in the University of Tokyo. As early as in 1985, S. Kochen suggested that the paradoxes of quantum physics could be overcome by developing a relational approach, which was needed at one time to solve the paradoxes of relativistic physics of space and time. It is also hoped that this entry will serve as a complement to Rovelli’s relational quantum mechanics (RQM). Historically, the theory of relativity and quantum mechanics were intertwined with each other and the compatibility between both theories was a main theme throughout the Bohr-Einstein debate. In both theories the physicists emphasized that only measurable quantities, that is, observables, belong in a theory. Bohr compared his approach to Einstein’s theory of relativity and asserted that in the treatment of quantum processes the complementarity of the measuring results cannot be ignored, just as in high-speed phenomena the relativity of observation cannot be neglected when the simultaneity comes into question. But Einstein replied: “A good joke should not be repeated too often.” The debate continued in connection with Einstein-Podolsky-Rosen (EPR) paradox, and Bohr proposed the relational conception of quantum states. Through their analysis Bohm and Schumacher concluded that the characteristic feature of this debate is the failure to communicate due to the absence of a full harmony of quantum mechanics with relativity. Modern attempts to embrace a relational approach with interpretations of quantum mechanics have been tried many times, ranging from Everett's relative-state interpretation (Everett, 1957), sigma algebra of interactive properties (Kochen, 1979), quantum reference systems (Bene, 1992), quantum theory of the universe (Smolin, 1995), to relational quantum mechanics (Rovelli, 1996). They more or less emphasize the relational nature of quantum states. For more information, please refer to the further reading list.

Tractatus Logico-Philosophicus (6.5)
In the Tractatus Logico-Philosophicus of Ludwig Wittgenstein, Proposition 6.5 seeks to ground his philosophy of action (Proposition 7: "Whereof one cannot speak, thereof one must be silent"). Although the historical significance of Tractatus is for its influence on the philosophers of logical empiricism, by providing them with a framework for a philosophy of science, and hence engineering, Wittgenstein actually wrote it as a work on ethics. See his propositions 6.4 onward. But his motivation for writing, and the style of presentation, follow Frege and Russell, below.

The World (Descartes)
The World, also called Treatise on the Light (French title: Traité du monde et de la lumière), is a book by René Descartes (1596–1650). Written between 1629 and 1633, it contains a nearly complete version of his philosophy, from method, to metaphysics, to physics and biology. Descartes espoused mechanical philosophy, a form of natural philosophy popular in the 17th century. He thought everything physical in the universe to be made of tiny "corpuscles" of matter. Corpuscularianism is closely related to atomism. The main difference was that Descartes maintained that there could be no vacuum, and all matter was constantly swirling to prevent a void as corpuscles moved through other matter. The World presents a corpuscularian cosmology in which swirling vortices explain, among other phenomena, the creation of the Solar System and the circular motion of planets around the Sun. The World rests on the heliocentric view, first explicated in Western Europe by Copernicus. Descartes delayed the book's release upon news of the Roman Inquisition's conviction of Galileo for "suspicion of heresy" and sentencing to house arrest. Descartes discussed his work on the book, and his decision not to release it, in letters with another philosopher, Marin Mersenne. Some material from The World was revised for publication as Principia philosophiae or Principles of Philosophy (1644), a Latin textbook at first intended by Descartes to replace the Aristotelian textbooks then used in universities. In the Principles the heliocentric tone was softened slightly with a relativist frame of reference. The last chapter of The World was published separately as De Homine (On Man) in 1662. The rest of The World was finally published in 1664, and the entire text in 1677.

Śrāvaka
Śrāvaka (Sanskrit) or Sāvaka (Pali) means "hearer" or, more generally, "disciple". This term is used in Buddhism and Jainism. In Jainism, a śrāvaka is any lay Jain so the term śrāvaka has been used for the Jain community itself (for example see Sarak and Sarawagi). Śrāvakācāras are the lay conduct outlined within the treaties by Śvetāmbara or Digambara mendicants. "In parallel to the prescriptive texts, Jain religious teachers have written a number of stories to illustrate vows in practice and produced a rich répertoire of characters.". In Buddhism, the term is sometimes reserved for distinguished disciples of the Buddha.

Relation (History of Concept)
The concept of relation as a term used in general philosophy has a long and complicated history. One of the interests for the Greek philosophers lay in the number of ways in which a particular thing might be described, and the establishment of a relation between one thing and another was one of these. A second interest lay in the difference between these relations and the things themselves. This was to culminate in the view that the things in themselves could not be known except through their relations. Debates similar to these continue into modern philosophy and include further investigations into types of relation and whether relations exist only in the mind or the real world or both. An understanding of types of relation is important to an understanding of relations between many things including those between people, communities and the wider world. Most of these are complex relations but of the simpler, analytical relations out of which they are formed there are generally held to be three types, although opinion on the number may differ. The three types are spatial relations which include geometry and number, relations of cause and effect, and the classificatory relations of similarity and difference that underlie knowledge. Going by different names in the sciences, mathematics, and the arts they can be thought of as three large families and it is the history of these that will be dealt with here.
