Gospel Of Judas
The Gospel of Judas is a non-canonical religious text. Its content consists of conversations between Jesus and his disciples, especially Judas Iscariot. The only copy of it known to exist is a Coptic language text that is part of the Codex Tchacos, which has been radiocarbon dated to 280 AD, plus or minus 60 years. Like the Gnostic texts of the Nag Hammadi library, this version is believed by most biblical scholars to be a translation of an original which was composed in the Greek language by Gnostic Christians in the 2nd century. Rejected as heresy by the early Christian church and lost for 1700 years, the document was rediscovered in Egypt in the 1970s. After undergoing extensive restoration and preservation, an English translation was first published in early 2006 by the National Geographic Society. History Authorship Like the four canonical gospels, the Gospel of Judas is anonymous. Date In early January 2005, researchers at the Arizona Accelerator Mass Spectrometr ...

Biblical Canon
A biblical canon is a set of texts (also called "books") which a particular Jewish or Christian religious community regards as part of the Bible. The English word ''canon'' comes from the Ancient Greek, Greek , meaning 'ruler, rule' or 'measuring stick'. The use of ''canon'' to refer to a set of religious scriptures was first used by David Ruhnken, in the 18th century. Various biblical canons have developed through debate and agreement on the part of the religious authorities of their respective faiths and denominations. Some books, such as the Jewish–Christian gospels, have been excluded from various canons altogether, but many Antilegomena, disputed books are considered to be biblical apocrypha or deuterocanonical by many, while some denominations may consider them fully canonical. Differences exist between the Hebrew Bible and Christian biblical canons, although the majority of manuscripts are shared in common. Different religious groups include different books in t ...

Matthew, Mark, Luke And John
"Matthew, Mark, Luke and John", also known as the "Black Paternoster", is an English children's bedtime prayer and nursery rhyme. It has a Roud Folk Song Index number of 1704. It may have origins in ancient Babylonian prayers and was being used in a Christian version in late Medieval Germany. The earliest extant version in English can be traced to the mid-sixteenth century. It was mentioned by English Protestant writers as a "popish" or magical charm. It is related to other prayers, including a "Green" and "White Paternoster", which can be traced to late medieval England and with which it is often confused. It has been the inspiration for a number of literary works by figures including Henry Wadsworth Longfellow and musical works by figures such as Gustav Holst. It has been the subject of alternative versions and satires. Lyrics The most common modern version of the verse is as follows: The Roud Folk Song Index, which catalogues folk songs and their variations by number, c ...

Against Heresies (Irenaeus)
''Against Heresies'' (Koine Greek: Ἔλεγχος καὶ ἀνατροπὴ τῆς ψευδωνύμου γνώσεως, ''Elenchos kai anatropē tēs pseudōnymou gnōseōs'', "Refutation and Overthrowal of Knowledge falsely so-called"), sometimes referred to by its Latin title ''Adversus Haereses'', is a work of Christian theology written in Greek language, Greek about the year 180 by Irenaeus, the bishop of Lugdunum (now Lyon in France). In it, Irenaeus identifies and describes several schools of Gnosticism, and other schools of Christian thought, whose beliefs he rejects as heresy. He contrasts them with Orthodoxy, orthodox Christianity. Until the discovery of the Nag Hammadi library, Library of Nag Hammadi in 1945, ''Against Heresies'' was the best surviving contemporary description of Gnosticism. Today, the treatise remains historically important as one of the first unambiguous attestations of the canonical gospel texts and some of the Pauline epistles. Irenaeus cites f ...

Loanword
A loanword (also a loan word, loan-word) is a word at least partly assimilated from one language (the donor language) into another language (the recipient or target language), through the process of borrowing. Borrowing is a metaphorical term that is well established in the linguistic field despite its acknowledged descriptive flaws: nothing is taken away from the donor language and there is no expectation of returning anything (i.e., the loanword). Loanwords may be contrasted with calques, in which a word is borrowed into the recipient language by being directly translated from the donor language rather than being adopted in (an approximation of) its original form. They must also be distinguished from cognates, which are words in two or more related languages that are similar because they share an etymological origin in the ancestral language, rather than because one borrowed the word from the other. Examples and related terms A loanword is distinguished from a calque (or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Textual Criticism
Textual criticism is a branch of textual scholarship, philology, and literary criticism that is concerned with the identification of textual variants, or different versions, of either manuscripts (mss) or of printed books. Such texts may range in dates from the earliest writing in cuneiform, impressed on clay, for example, to multiple unpublished versions of a 21st-century author's work. Historically, scribes who were paid to copy documents may have been literate, but many were simply copyists, mimicking the shapes of letters without necessarily understanding what they meant. This means that unintentional alterations were common when copying manuscripts by hand. Intentional alterations may have been made as well, for example, the censoring of printed work for political, religious or cultural reasons. The objective of the textual critic's work is to provide a better understanding of the creation and historical transmission of the text and its variants. This understanding may ...

X-ray Diffraction
X-ray diffraction is a generic term for phenomena associated with changes in the direction of X-ray beams due to interactions with the electrons around atoms. It occurs due to elastic scattering, when there is no change in the energy of the waves. The resulting map of the directions of the X-rays far from the sample is called a diffraction pattern. It is different from X-ray crystallography which exploits X-ray diffraction to determine the arrangement of atoms in materials, and also has other components such as ways to map from experimental diffraction measurements to the positions of atoms. This article provides an overview of X-ray diffraction, starting with the early #History, history of x-rays and the discovery that they have the right spacings to be diffracted by crystals. In many cases these diffraction patterns can be #Introduction to x-ray diffraction theory, Interpreted using a single scattering or kinematical theory with conservation of energy (#Ewald's sphere, wave vecto ...

Transmission Electron Microscopy
Transmission electron microscopy (TEM) is a microscopy technique in which a beam of electrons is transmitted through a specimen to form an image. The specimen is most often an ultrathin section less than 100 nm thick or a suspension on a grid. An image is formed from the interaction of the electrons with the sample as the beam is transmitted through the specimen. The image is then magnified and focused onto an imaging device, such as a fluorescent screen, a layer of photographic film, or a detector such as a scintillator attached to a charge-coupled device or a direct electron detector. Transmission electron microscopes are capable of imaging at a significantly higher resolution than light microscopes, owing to the smaller de Broglie wavelength of electrons. This enables the instrument to capture fine detail—even as small as a single column of atoms, which is thousands of times smaller than a resolvable object seen in a light microscope. Transmission electron micr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scanning Electron Microscope
A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons. The electrons interact with atoms in the sample, producing various signals that contain information about the surface topography and composition. The electron beam is scanned in a raster scan pattern, and the position of the beam is combined with the intensity of the detected signal to produce an image. In the most common SEM mode, secondary electrons emitted by atoms excited by the electron beam are detected using a secondary electron detector ( Everhart–Thornley detector). The number of secondary electrons that can be detected, and thus the signal intensity, depends, among other things, on specimen topography. Some SEMs can achieve resolutions better than 1 nanometer. Specimens are observed in high vacuum in a conventional SEM, or in low vacuum or wet conditions in a variable pressure or environmental SEM, an ...

Raman Spectroscopy
Raman spectroscopy () (named after physicist C. V. Raman) is a Spectroscopy, spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. Raman spectroscopy is commonly used in chemistry to provide a structural fingerprint by which molecules can be identified. Raman spectroscopy relies upon inelastic scattering of photons, known as Raman scattering. A source of monochromatic light, usually from a laser in the visible spectrum, visible, near infrared, or ultraviolet, near ultraviolet range is used, although X-ray Raman scattering, X-rays can also be used. The laser light interacts with molecular vibrations, phonons or other excitations in the system, resulting in the energy of the laser photons being shifted up or down. The shift in energy gives information about the vibrational modes in the system. Time-resolved spectroscopy and infrared spectroscopy typically yields similar y ...

Infrared Spectroscopy
Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms. It can be used to characterize new materials or identify and verify known and unknown samples. The method or technique of infrared spectroscopy is conducted with an instrument called an infrared spectrometer (or spectrophotometer) which produces an infrared spectrum. An IR spectrum can be visualized in a graph of infrared light absorbance (or transmittance) on the vertical axis vs. frequency, wavenumber or wavelength on the horizontal axis. Typical units of wavenumber used in IR spectra are reciprocal centimeters, with the symbol cm−1. Units of IR wavelength are commonly given in micrometers (formerly called "microns"), symbol μm, which are related to the wavenumber in a reciprocal way ...

Polarized Light Microscopy
Polarized light microscopy can mean any of a number of optical microscopy techniques involving polarized light. Simple techniques include illumination of the sample with polarized light. Directly transmitted light can, optionally, be blocked with a polariser oriented at 90 degrees to the illumination. More complex microscopy techniques which take advantage of polarized light include differential interference contrast microscopy and interference reflection microscopy. Scientists will often use a device called a polarizing plate to convert natural light into polarized light. These illumination techniques are most commonly used on birefringent samples where the polarized light interacts strongly with the sample and so generating contrast with the background. Polarized light microscopy is used extensively in optical mineralogy. Although the invention of the polarizing microscope is typically attributed to David Brewster around 1815, Brewster clearly acknowledges the priority of H ...

Codex
The codex (: codices ) was the historical ancestor format of the modern book. Technically, the vast majority of modern books use the codex format of a stack of pages bound at one edge, along the side of the text. But the term ''codex'' is now reserved for older manuscript books, which mostly used sheets of vellum, parchment, or papyrus, rather than paper. By convention, the term is also used for any Aztec codex (although the earlier examples do not actually use the codex format), Maya codices and other pre-Columbian manuscripts. Library practices have led to many European manuscripts having "codex" as part of their usual name, as with the Codex Gigas, while most do not. Modern books are divided into paperback (or softback) and those bound with stiff boards, called hardbacks. Elaborate historical bindings are called treasure bindings. At least in the Western world, the main alternative to the paged codex format for a long document was the continuous scroll, which was the ...
