Photographic platePhotographic plates preceded photographic film as a capture medium in photography, and were still used in some communities up until the late 20th century. The light-sensitive emulsion of silver salts was coated on a glass plate, typically thinner than common window glass. Glass plates were far superior to film for research-quality imaging because they were stable and less likely to bend or distort, especially in large-format frames for wide-field imaging. Early plates used the wet collodion process.
Color televisionColor television (American English) or colour television (Commonwealth English) is a television transmission technology that includes color information for the picture, so the video image can be displayed in color on the television set. It improves on the monochrome or black-and-white television technology, which displays the image in shades of gray (grayscale). Television broadcasting stations and networks in most parts of the world upgraded from black-and-white to color transmission between the 1940s and the 1980s.
ImagingImaging is the representation or reproduction of an object's form; especially a visual representation (i.e., the formation of an ). Imaging technology is the application of materials and methods to create, preserve, or duplicate images. Imaging science is a multidisciplinary field concerned with the generation, collection, duplication, analysis, modification, and visualization of images, including imaging things that the human eye cannot detect.
Online encyclopediaAn online encyclopedia, also called an Internet encyclopedia, is a digital encyclopedia accessible through the Internet. Examples include Wikipedia and Encyclopædia Britannica. In January 1995, Project Gutenberg started to publish the ASCII text of the Encyclopædia Britannica, 11th edition (1911), but disagreement about the method halted the work after the first volume. For trademark reasons this has been published as the Gutenberg Encyclopedia. Project Gutenberg later restarted work on digitising and proofreading this encyclopedia.
Historical JesusThe term "historical Jesus" refers to the life and teachings of Jesus as interpreted through critical historical methods, in contrast to what are traditionally religious interpretations. It also considers the historical and cultural contexts in which Jesus lived. Virtually all scholars of antiquity accept that Jesus was a historical figure, and attempts to deny his historicity have been consistently rejected by the scholarly consensus as a fringe theory.
Historical criticismHistorical criticism, also known as the historical-critical method or higher criticism, is a branch of criticism that investigates the origins of ancient texts in order to understand "the world behind the text". While often discussed in terms of Jewish and Christian writings from ancient times, historical criticism has also been applied to other religious and secular writings from various parts of the world and periods of history.
Historical revisionismIn historiography, historical revisionism is the reinterpretation of a historical account. It usually involves challenging the orthodox (established, accepted or traditional) views held by professional scholars about a historical event or timespan or phenomenon, introducing contrary evidence, or reinterpreting the motivations and decisions of the people involved. The revision of the historical record can reflect new discoveries of fact, evidence, and interpretation, which then results in revised history.
WikipediaWikipedia is a free-content online encyclopedia written and maintained by a community of volunteers, collectively known as Wikipedians, through open collaboration and using a wiki-based editing system called MediaWiki. Wikipedia is the largest and most-read reference work in history, and has consistently been one of the 10 most popular websites. Created by Jimmy Wales and Larry Sanger on January 15, 2001, it is hosted by the Wikimedia Foundation, an American nonprofit organization.
Key events of the 20th centuryThe 20th century changed the world in unprecedented ways. The World Wars sparked tension between countries and led to the creation of atomic bombs, the Cold War led to the Space Race and the creation of space-based rockets, and the World Wide Web was created. These advancements have played a significant role in citizens' lives and shaped the 21st century into what it is today. From 1914 to 1918, the First World War, and its aftermath, caused major changes in the power balance of the world, destroying or transforming some of the most powerful empires.
