Big History
Big History is an academic discipline which examines history from the Big Bang to the present. Big History resists specialization, and searches for universal patterns or trends. It examines long time frames using a multidisciplinary approach based on combining numerous disciplines from science and the humanities, and explores human existence in the context of this bigger picture. It integrates studies of the cosmos, Earth, life, and humanity using empirical evidence to explore cause-and-effect relations, and is taught at universities and primary and secondary schools often using web-based interactive presentations. Historian David Christian has been credited with coining the term "Big History" while teaching one of the first such courses at Macquarie University. An all-encompassing study of humanity's relationship to cosmology and natural history has been pursued by scholars since the Renaissance, and the new field, Big History, continues such work. Comparison with conven ...

CMB Timeline300 No WMAP
In Big Bang cosmology the cosmic microwave background (CMB, CMBR) is electromagnetic radiation that is a remnant from an early stage of the universe, also known as "relic radiation". The CMB is faint cosmic background radiation filling all space. It is an important source of data on the early universe because it is the oldest electromagnetic radiation in the universe, dating to the epoch of recombination when the first atoms were formed. With a traditional optical telescope, the space between stars and galaxies (the background) is completely dark (see: Olbers' paradox). However, a sufficiently sensitive radio telescope shows a faint background brightness, or glow, almost uniform, that is not associated with any star, galaxy, or other object. This glow is strongest in the microwave region of the radio spectrum. The accidental discovery of the CMB in 1965 by American radio astronomers Arno Penzias and Robert Wilson was the culmination of work initiated in the 1940s, and earned ...

Cosmology
Cosmology () is a branch of physics and metaphysics dealing with the nature of the universe. The term ''cosmology'' was first used in English in 1656 in Thomas Blount (lexicographer), Thomas Blount's ''Glossographia'', and in 1731 taken up in Latin by German philosophy, German philosopher Christian Wolff (philosopher), Christian Wolff, in ''Cosmologia Generalis''. Religious cosmology, Religious or mythological cosmology is a body of beliefs based on Mythology, mythological, Religion, religious, and Esotericism, esoteric literature and traditions of Cosmogony, creation myths and eschatology. In the science of astronomy it is concerned with the study of the chronology of the universe. Physical cosmology is the study of the observable universe's origin, its large-scale structures and dynamics, and the ultimate fate of the universe, including the laws of science that govern these areas. It is investigated by scientists, such as astronomers and physicists, as well as Philosophy, ph ...

Writing
Writing is a medium of human communication which involves the representation of a language through a system of physically Epigraphy, inscribed, Printing press, mechanically transferred, or Word processor, digitally represented Symbols (semiotics), symbols. Writing systems do not themselves constitute human languages (with the debatable exception of computer languages); they are a means of rendering language into a form that can be reconstructed by other humans separated by time and/or space. While not all languages use a writing system, those that do can complement and extend capacities of spoken language by creating durable forms of language that can be transmitted across space (e.g. Letter (message), written correspondence) and stored over time (e.g. libraries or other public records). It has also been observed that the activity of writing itself can have knowledge-transforming effects, since it allows humans to externalize their thinking in forms that are easier to reflect ...

Civilization
A civilization (or civilisation) is any complex society characterized by the development of a state, social stratification, urbanization, and symbolic systems of communication beyond natural spoken language (namely, a writing system). Civilizations are intimately associated with additional characteristics such as centralization, the domestication of plant and animal species (including humans), specialization of labour, culturally-ingrained ideologies of progress, monumental architecture, taxation, societal dependence upon farming, and expansionism. Historically, a civilization has often been understood as a larger and "more advanced" culture, in implied contrast to smaller, supposedly less advanced cultures. In this broad sense, a civilization contrasts with non-centralized tribal societies, including the cultures of nomadic pastoralists, Neolithic societies or hunter-gatherers; however, sometimes it also contrasts with the cultures found within civilizations themselv ...

Agriculture
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals (grains), vegetables, fruits, cooking oils, meat, milk, ...

Modernity
Modernity, a topic in the humanities and social sciences, is both a historical period (the modern era) and the ensemble of particular socio-cultural norm (social), norms, attitudes and practices that arose in the wake of the Renaissancein the "Age of Enlightenment, Age of Reason" of 17th-century thought and the 18th-century "Age of Enlightenment, Enlightenment". Some commentators consider the era of modernity to have ended by 1930, with World War II in 1945, or the 1980s or 1990s; the following era is called postmodernity. The term "contemporary history" is also used to refer to the post-1945 timeframe, without assigning it to either the modern or postmodern era. (Thus "modern" may be used as a name of a particular era in the past, as opposed to meaning "the current era".) Depending on the field, "modernity" may refer to different time periods or qualities. In historiography, the 16th to 18th centuries are usually described as early modern, while the long 19th century correspond ...

Geologic Time Scale
The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardized international units of geologic time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely define ...

Macrohistory
Macrohistory seeks out large, long-term trends in world history in search of ultimate patterns by a comparison of proximate details. It favors a comparative or world-historical perspective to determine the roots of changes as well as the developmental paths of society or a historical process. A macrohistorical study might examine Japanese feudalism and European feudalism to decide whether feudal structures are an inevitable outcome because of certain conditions. Macrohistorical studies often "assume that macro-historical processes repeat themselves in explainable and understandable ways." The approach can identify stages in the development of humanity as a whole such as the large-scale direction towards greater rationality, greater liberty or the development of productive forces and communist society, among others. Description Macrohistory is distinguished from microhistory, which involves the rigorous and in-depth study of a single event in history. However, these two can be co ...

Microhistory
Microhistory is a genre of history that focuses on small units of research, such as an event, community, individual or a settlement. In its ambition, however, microhistory can be distinguished from a simple case study insofar as microhistory aspires to " sklarge questions in small places", according to the definition given by Charles Joyner. It is closely associated with social and cultural history. Origins Microhistory became popular in Italy in the 1970s. According to Giovanni Levi, one of the pioneers of the approach, it began as a reaction to a perceived crisis in existing historiographical approaches. Carlo Ginzburg, another of microhistory's founders, has written that he first heard the term used around 1977, and soon afterwards began to work with Levi and Simona Cerutti on ''Microstorie'', a series of microhistorical works. The word "microhistory" dates back to 1959, when the American historian George R. Stewart published ''Pickett's Charge: A Microhistory of the Final Attac ...

ChronoZoom
ChronoZoom is a free open source project that visualizes time on the broadest possible scale from the Big Bang to the present day. Conceived by Walter Alvarez and Roland Saekow and developed by the department of Earth and Planetary Science at the University of California, Berkeley in collaboration with Microsoft Research and Moscow State University, Alvarez unveiled the first ChronoZoom prototype at UC Berkeley's 2010 Faculty Research Lecture. Although that demo is no longer available to the public online, a second version rewritten in HTML5 is now available and open source. ChronoZoom was inspired by the study of Big History, and it approaches the documentation and visualization of time and history in the same way that Google Earth deals with geography. ChronoZoom allows users to see the true scale of time over cosmic, geologic, biological and social periods. Purpose The primary goal of ChronoZoom is to make time relationships between different studies of history clear and vivid ...

Big History Project
OER Project is a non-profit open educational resources provider co-founded in 2011 by Bill Gates and David Christian. Originally known as Big History Project (BHP), the titular course was intended to to enable the global teaching of the subject of Big History, which has been described as "the attempt to understand, in a unified way, the history of Cosmos, Earth, Life and Humanity." The company rebranded as OER Project in 2019 and now offers World History Project, Climate Project, and other courses in addition to the original BHP curriculum. History of OER Project Bill Gates became interested in the topic when he heard "Big History: The Big Bang, Life on Earth, and the Rise of Humanity," a 48-lecture course taught by David Christian and published by The Teaching Company. For Gates, "he hristianreally blew me away. Here's a guy who's read across the sciences, humanities, and social sciences and brought it together in a single framework. It made me wish that I could have taken big ...

Crash Course (YouTube)
''Crash Course'' (sometimes stylized as ''CrashCourse'') is an educational YouTube channel started by John Green and Hank Green (collectively the Green brothers), who first rose to fame on the YouTube platform through their ''Vlogbrothers'' channel. ''Crash Course'' was one of the hundred initial channels funded by YouTube's $100 million original channel initiative. The channel launched a preview on December 2, 2011, and , it has accumulated over 14 million subscribers and 1.6 billion video views. The channel launched with John and Hank presenting their respective ''World History'' and ''Biology'' series; the early history of the channel continued the trend of John and Hank presenting humanities and science courses, respectively. In November 2014, Hank announced a partnership with PBS Digital Studios, which would allow the channel to produce more courses. As a result, multiple additional hosts joined the show to increase the number of concurrent series. To date, there are 44 ma ...
