Big History
Big History is an academic discipline that examines history from the Big Bang to the present day, 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. It 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 causality, cause-and-effect relations. It is taught at universities as well as primary and secondary schools often using web-based interactive presentations. Historian David Christian (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 H ...

CMB Timeline300 No WMAP
The cosmic microwave background (CMB, CMBR), or relic radiation, is microwave radiation that fills all space in the observable universe. With a standard optical telescope, the background space between stars and galaxies is almost completely dark. However, a sufficiently sensitive radio telescope detects a faint background glow that is almost isotropic, uniform and is not associated with any star, galaxy, or other astronomical object, object. This glow is strongest in the microwave region of the electromagnetic spectrum. The accidental Discovery of cosmic microwave background radiation, discovery of the CMB in 1965 by American radio astronomers Arno Allan Penzias and Robert Woodrow Wilson was the culmination of work initiated in the 1940s. The CMB is landmark evidence of the Big Bang scientific theory, theory for the origin of the universe. In the Big Bang cosmological models, during the earliest periods, the universe was filled with an Opacity (optics), opaque fog of dense, hot ...

Cosmology
Cosmology () is a branch of physics and metaphysics dealing with the nature of the universe, the cosmos. The term ''cosmology'' was first used in English in 1656 in Thomas Blount's ''Glossographia'', with the meaning of "a speaking of the world". In 1731, German philosopher Christian Wolff used the term cosmology in Latin (''cosmologia'') to denote a branch of metaphysics that deals with the general nature of the physical world. Religious or mythological cosmology is a body of beliefs based on mythological, religious, and esoteric literature and traditions of creation myths and eschatology. In the science of astronomy, cosmology 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, including astronomers and physicists, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Universe
The universe is all of space and time and their contents. It comprises all of existence, any fundamental interaction, physical process and physical constant, and therefore all forms of matter and energy, and the structures they form, from sub-atomic particles to entire Galaxy filament, galactic filaments. Since the early 20th century, the field of cosmology establishes that space and time emerged together at the Big Bang ago and that the Expansion of the universe, universe has been expanding since then. The observable universe, portion of the universe that can be seen by humans is approximately 93 billion light-years in diameter at present, but the total size of the universe is not known. Some of the earliest Timeline of cosmological theories, cosmological models of the universe were developed by ancient Greek philosophy, ancient Greek and Indian philosophy, Indian philosophers and were geocentric model, geocentric, placing Earth at the center. Over the centuries, more prec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humankind
Humans (''Homo sapiens'') or modern humans are the most common and widespread species of primate, and the last surviving species of the genus ''Homo''. They are great apes characterized by their hairlessness, bipedalism, and high intelligence. Humans have large brains, enabling more advanced cognitive skills that facilitate successful adaptation to varied environments, development of sophisticated tools, and formation of complex social structures and civilizations. Humans are highly social, with individual humans tending to belong to a multi-layered network of distinct social groups — from families and peer groups to corporations and political states. As such, social interactions between humans have established a wide variety of values, social norms, languages, and traditions (collectively termed institutions), each of which bolsters human society. Humans are also highly curious: the desire to understand and influence phenomena has motivated humanity's development ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boston Globe Magazine
''The Boston Globe,'' also known locally as ''the Globe'', is an American daily newspaper founded and based in Boston, Massachusetts. The newspaper has won a total of 27 Pulitzer Prizes. ''The Boston Globe'' is the oldest and largest daily newspaper in Boston and tenth-largest newspaper by print circulation in the nation as of 2023. Founded in 1872, the paper was mainly controlled by Irish Catholic interests before being sold to Charles H. Taylor and his family. After being privately held until 1973, it was sold to ''The New York Times'' in 1993 for $1.1billion, making it one of the most expensive print purchases in United States history. The newspaper was purchased in 2013 by Boston Red Sox and Liverpool F.C. owner John W. Henry for $70million from The New York Times Company, having lost over 90% of its value in 20 years. The chief print rival of ''The Boston Globe'' is the ''Boston Herald'', whose circulation is smaller and is shrinking faster. The newspaper is "one of t ...

Pattern
A pattern is a regularity in the world, in human-made design, or in abstract ideas. As such, the elements of a pattern repeat in a predictable manner. A geometric pattern is a kind of pattern formed of geometric shapes and typically repeated like a wallpaper design. Any of the senses may directly observe patterns. Conversely, abstract patterns in science, mathematics, or language may be observable only by analysis. Direct observation in practice means seeing visual patterns, which are widespread in nature and in art. Visual patterns in nature are often chaotic, rarely exactly repeating, and often involve fractals. Natural patterns include spirals, meanders, waves, foams, tilings, cracks, and those created by symmetries of rotation and reflection. Patterns have an underlying mathematical structure; indeed, mathematics can be seen as the search for regularities, and the output of any function is a mathematical pattern. Similarly in the sciences, theories explain and pred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theme (narrative)
In contemporary literary studies, a theme is a central topic, subject, or message within a narrative. Themes can be divided into two categories: a work's ''thematic concept'' is what readers "think the work is about" and its ''thematic statement'' being "what the work says about the subject". The most common contemporary understanding of theme is an idea or point that is central to a story, which can often be summed in a single abstract noun (for example, love, death, betrayal, patriotism, or parenthood) or noun phrase (for example, coming of age, grief during wartime, or the importance of community). Typical examples of themes of this type are conflict between the individual and society; coming of age; humans in conflict with technology; nostalgia; and the dangers of unchecked ambition. A theme may be exemplified by the actions, utterances, or thoughts of a character in a novel. An example of this would be the thematic idea of loneliness in John Steinbeck's '' Of Mice and M ...

Writing
Writing is the act of creating a persistent representation of language. A writing system includes a particular set of symbols called a ''script'', as well as the rules by which they encode a particular spoken language. Every written language arises from a corresponding spoken language; while the use of language is universal across human societies, most spoken languages are not written. Writing is a cognitive and social activity involving neuropsychological and physical processes. The outcome of this activity, also called ''writing'' (or a ''text'') is a series of physically inscribed, mechanically transferred, or digitally represented symbols. Reading is the corresponding process of interpreting a written text, with the interpreter referred to as a ''reader''. In general, writing systems do not constitute languages in and of themselves, but rather a means of encoding language such that it can be read by others across time and space. While not all languages use a writ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civilization
A civilization (also spelled civilisation in British English) is any complex society characterized by the development of state (polity), the state, social stratification, urban area, urbanization, and symbolic systems of communication beyond natural language, signed or spoken languages (namely, writing systems). Civilizations are organized around densely-populated settlements, divided into more or less rigid hierarchy, hierarchical social classes of division of labour, often with a ruling elite and a subordinate urban and rural populations, which engage in intensive agriculture, mining, small-scale manufacture and trade. Civilization concentrates power, extending human control over the rest of nature, including over other human beings. Civilizations are characterized by elaborate agriculture, architecture, infrastructure, Innovation, technological advancement, currency, taxation, regulation, and specialization of labour. Historically, a civilization has often been understo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agriculture
Agriculture encompasses crop and livestock production, aquaculture, and forestry for food and non-food products. Agriculture was a key factor in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in the cities. While humans started gathering grains at least 105,000 years ago, nascent farmers only began planting them around 11,500 years ago. Sheep, goats, pigs, and cattle were domesticated around 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. In the 20th century, industrial agriculture based on large-scale monocultures came to dominate agricultural output. , small farms produce about one-third of the world's food, but large farms are prevalent. The largest 1% of farms in the world are greater than and operate more than 70% of the world's farmland. Nearly 40% of agricultural land is found on farms larger than . However, five of every six farm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modernity
Modernity, a topic in the humanities and social sciences, is both a historical period (the modern era) and the ensemble of particular Society, socio-Culture, 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. Commentators variously consider the era of modernity to have ended by 1930, with World War II in 1945, or as late as the period falling between the 1980s and 1990s; the following era is often referred to as "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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
