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.

Hobbes's Moral and Political Philosophy
Thomas Hobbes’s moral and political philosophy is constructed around the basic premise of social and political order, explaining how humans should live in peace under a sovereign power so as to avoid conflict within the ‘state of nature’. Hobbes’s moral philosophy and political philosophy are significantly intertwined; his moral thought is based around ideas of human nature, which determine the interactions that make up his political philosophy.  Hobbes’s moral philosophy therefore provides justification for, and informs, the theories of sovereignty and the state of nature that underpin his political philosophy. In utilising methods of deductive reasoning and motion science, Hobbes examines human emotion, reason and knowledge to construct his ideas of human nature (moral philosophy). This methodology critically influences his politics, determining the interactions of conflict (in the state of nature) which necessitate the creation of a politically authoritative State to ensure the maintenance of peace and cooperation. This method is used and developed in works such as The Elements of Law (1640), De Cive (1642), Leviathan (1651) and Behemoth (1681).

History of X-ray Research in Colonial India
This is the stroy of the beginning of X-ray research in colonial India and its progress to understand the India's respectable position globally in X-ray researh in modern times.The history of X-ray research in colonial India started with the procurement of X-ray tube by Dr. Mahendralal Sircar within six months of the discovery of X-rays at the Indian Association for the Cultivation of Science (IACS). The first application of X-rays for clinical purposes was done, in private capacity, independently by Dr. Sircar and Sir J.C. Bose. After his return from England in 1921, C.V. Raman initiated serious X-ray scattering studies in the structure of matter at the IACS which proliferated to all parts of India and laid the foundation stone of modern X-ray research in India.

History of Taoism
The history of Taoism stretches throughout Chinese history. Originating in prehistoric China, it has exerted a powerful influence over Chinese culture throughout the ages. Taoism evolved in response to changing times, with its doctrine and associated practices being revised and refined. The acceptance of Taoism by the ruling class has waxed and waned, alternately enjoying periods of favor and rejection. Most recently, Taoism has emerged from a period of suppression and is undergoing a revival in China. Laozi is traditionally regarded as the founder of Taoist religion and is closely associated in this context with "original", or "primordial", Taoism. Whether he actually existed is disputed, however, the work attributed to him - the Daodejing - is dated to the 4th or 3rd century BC. However, Taoism clearly predates Laozi (Lao Tzu) as he refers to "The Tao masters of antiquity" in Chapter 15 of the Daodejing (Tao Te Ching). Moreover, the Yellow Emperor, Huangdi (2697–2597 BCE) Is often associated with origin of the Tao. Sinologist Isabelle Robinet identifies four components in the emergence of Taoism: Some elements of Taoism may be traced to prehistoric folk religions in China that later coalesced into a Taoist tradition. In particular, many Taoist practices drew from the Warring-States-era phenomena of the Wu (shaman) (connected to the "shamanism" of Southern China) and the Fangshi (which probably derived from the "archivist-soothsayers of antiquity, one of whom supposedly was Laozi himself"), even though later Taoists insisted that this was not the case. Both terms were used to designate individuals dedicated to "... magic, medicine, divination,... methods of longevity and to ecstatic wanderings" as well as exorcism; in the case of the wu, "shamans" or "sorcerers" is often used as a translation. The fangshi were philosophically close to the School of Yin-Yang, and relied much on astrological and calendrical speculations in their divinatory activities.

History of Purgatory
The idea of purgatory has roots that date back into antiquity. A sort of proto-purgatory called the "celestial Hades" appears in the writings of Plato and Heraclides Ponticus and in many other pagan writers. This concept is distinguished from the Hades of the underworld described in the works of Homer and Hesiod. In contrast, the celestial Hades was understood as an intermediary place where souls spent an undetermined time after death before either moving on to a higher level of existence or being reincarnated back on earth. Its exact location varied from author to author. Heraclides of Pontus thought it was in the Milky Way; the Academicians, the Stoics, Cicero, Virgil, Plutarch, the Hermetical writings situated it between the Moon and the Earth or around the Moon; while Numenius and the Latin Neoplatonists thought it was located between the sphere of the fixed stars and the Earth. Perhaps under the influence of Hellenistic thought, we find another intermediate state entering Jewish religious thought in the last centuries B.C.E. In Maccabees we find the practice of prayer for the dead with a view to their after life purification a practice accepted by some Christians. The same practice appears in other traditions, such as the medieval Chinese Buddhist practice of making offerings on behalf of the dead, who are said to suffer numerous trials. Among other reasons, Catholic belief in purgatory is based on the practice of prayer for the dead. Descriptions and doctrine regarding purgatory developed over the centuries. Those who believe in purgatory interpret extra-biblical passages such as 2 Maccabees 12:41-46 (not accepted as Scripture by Protestants but recognized by Orthodox and Catholics), and biblical passages such as 2 Timothy 1:18, Matthew 12:32, Luke 16:19-16:26, Luke 23:43, 1 Corinthians 3:11-3:15 and Hebrews 12:29 as support for prayer for the dead, an active interim state for the dead prior to the resurrection, and purifying flames after death. The first Christians looked forward to the imminent return of Christ and did not develop detailed beliefs about the interim state. Gradually, Christians, especially in the West, took an interest in circumstances of the interim state between one's death and the future resurrection. Christians both East and West prayed for the dead in this interim state, although theologians in the East refrained from defining it. Augustine of Hippo distinguished between the purifying fire that saves and eternal consuming fire for the unrepentant. Gregory the Great established a connection between earthly penance and purification after death. All Soul's Day, established in the 10th century, turned popular attention to the condition of departed souls. The idea of Purgatory as a physical place (like heaven and hell) was "born" in the late 11th century. Medieval theologians concluded that the purgatorial punishments consisted of material fire. The Western formulation of purgatory proved to be a sticking point in the Great Schism between East and West. The Catholic Church believes that the living can help those whose purification from their sins is not yet completed not only by praying for them but also by gaining indulgences for them as an act of intercession. The later Middle Ages saw the growth of considerable abuses, such as the unrestricted sale of indulgences by professional "pardoners" sent to collect contributions to projects such as the rebuilding of St. Peter's Basilica in Rome. These abuses were one of the factors that led to the Protestant Reformation. Most Protestants rejected the idea of purgatory, as never clearly mentioned in Luther's canon of the Bible, which excludes the Deuterocanonical books. Modern Catholic theologians have softened the punitive aspects of purgatory and stress instead the willingness of the dead to undergo purification as preparation for the happiness of heaven The English Anglican scholar John Henry Newman argued, in a book that he wrote before becoming Catholic, that the essence of the doctrine on purgatory is locatable in ancient tradition, and that the core consistency of such beliefs are evidence that Christianity was "originally given to us from heaven".

History of Islam
The history of Islam concerns the political, social, economic and cultural developments of the Islamic civilization. Despite concerns about the reliability of early sources, most historians believe that Islam originated in Mecca and Medina at the start of the 7th century, approximately 600 years after the founding of Christianity. Muslims, however, believe that it did not start with Muhammad, but that it was the original faith of others whom they regard as prophets, such as Jesus, David, Moses, Abraham, Noah and Adam. In 610 CE, Muhammad began receiving what Muslims consider to be divine revelations. Muhammad's message won over a handful of followers and was met with increasing opposition from Meccan notables. In 618, after he lost protection with the death of his influential uncle Abu Talib, Muhammad migrated to the city of Yathrib (now known as Medina). With Muhammad's death in 632, disagreement broke out over who would succeed him as leader of the Muslim community which was eventually resurrected leading to the First Fitna. The dispute would intensify greatly after the Battle of Karbala, in which Muhammad's grandson Hussein ibn Ali was killed by the ruling Umayyad Caliph Yazid I, and the outcry for revenge divided the early Islamic community. By the 8th century, the Islamic empire extended from Iberia in the west to the Indus river in the east. Polities such as those ruled by the Umayyads (in the Middle East and later in Iberia), Abbasids, Fatimids, and Mamluks were among the most influential powers in the world. The Islamic Golden Age gave rise to many centers of culture and science and produced notable astronomers, mathematicians, doctors and philosophers during the Golden Age of Islam. In the early 13th century, the Delhi Sultanate took over northern parts of Indian subcontinent. In the 13th and 14th centuries, destructive Mongol invasions from the East, along with the loss of population in the Black Death, greatly weakened the traditional centers of the Islamic world, stretching from Persia to Egypt, but in the Early Modern period, the Ottomans, the Safavids, and the Mughals were able to create new world powers again. During the 19th and early 20th centuries, most parts of the Muslim world fell under the influence or direct control of European "Great Powers." Their efforts to win independence and build modern nation states over the course of the last two centuries continue to reverberate to the present day.

Historicism (Christianity)
In Christian eschatology, historicism is a method of interpretation of biblical prophecies which associates symbols with historical persons, nations or events. The main primary texts of interest to Christian historicists include apocalyptic literature, such as the Book of Daniel and the Book of Revelation. It sees the prophecies of Daniel as being fulfilled throughout history, extending from the past through the present to the future. It is sometimes called the continuous historical view. Commentators have also applied historicist methods to ancient Jewish history, to the Roman Empire, to Islam, to the Papacy, to the Modern era, and to the end time. The historicist method starts with Daniel 2 and works progressively through consecutive prophecies of the book–chapters 7, 8 and 11–resulting in a view of Daniel's prophecies very different from preterism and futurism. Almost all Protestant Reformers from the Reformation into the 19th century held historicist views.

Historical Reliability of the Gospels
The historical reliability of the Gospels refers to the reliability and historic character of the four New Testament gospels as historical documents. Some believe that all four canonical gospels meet the five criteria for historical reliability; and others say that little in the gospels is considered to be historically reliable. Almost all scholars of antiquity agree that Jesus existed, but scholars differ on the historicity of specific episodes described in the Biblical accounts of Jesus, and the only two events subject to "almost universal assent" are that Jesus was baptized by John the Baptist and was crucified by the order of the Roman Prefect Pontius Pilate. Elements whose historical authenticity is disputed include the two accounts of the Nativity of Jesus, the miraculous events including the resurrection, and certain details about the crucifixion. According to the majority viewpoint the gospels of Matthew, Mark, and Luke, collectively referred to as the Synoptic Gospels, are the primary sources of historical information about Jesus and of the religious movement he founded. The fourth gospel, the Gospel of John, differs greatly from the first three gospels. Historians often study the historical reliability of the Acts of the Apostles when studying the reliability of the gospels, as Acts was seemingly written by the same author as the Gospel of Luke. Historians subject the gospels to critical analysis, attempting to differentiate, rather than authenticate, reliable information from possible inventions, exaggerations, and alterations. Since there are more than 15,000 New Testament manuscripts which present hundreds of thousands of textual variants, scholars use textual criticism to determine which gospel variants could theoretically be taken as 'original'. To answer this question, scholars have to ask who wrote the gospels, when they wrote them, what was their objective in writing them, what sources the authors used, how reliable these sources were, and how far removed in time the sources were from the stories they narrate, or if they were altered later. Scholars can also look into the internal evidence of the documents, to see if, for example, the document is misquoting texts from the Hebrew Tanakh, is making claims about geography that were incorrect, if the author appears to be hiding information, or if the author has made up a certain prophecy. Finally, scholars turn to external sources, including the testimony of early church leaders, writers outside the church (mainly Jewish and Greco-Roman historians) who would have been more likely to have criticized the early churches, and to archaeological evidence.

Historical Ecology in Brazil
The term “Historical Ecology” has been defined by two different research scholarships: (1) as a field that draws upon diverse evidence to trace complex, long-term relationships between humanity and Earth; and (2) as a field related to evolutionary ecology and the use of phylogenetic systematics, which may or may not involve anthropogenic agency. Here we embrace and refer to the first definition. Hence, Historical Ecology is a multidisciplinary field (or research program) that investigates human-environment relationships resulting in continuous spatial, environmental, historical, and cultural interactions. Its primary focus is the physical evidence etched in the landscape. The use of landscape as an analytical framework and spatial unit is valuable and widely used in Historical Ecology.
