Collapse: How Societies Choose to Fail or Succeed (titled Collapse: How Societies Choose to Fail or Survive for the British edition) is a 2005 book by academic and popular science author Jared Diamond, in which the author first defines collapse: "a drastic decrease in human population size and/or political/economic/social complexity, over a considerable area, for an extended time."
Three examples of Turing patterns Six stable states from Turing equations, the last one forms Turing patterns. The Turing pattern is a concept introduced by English mathematician Alan Turing in a 1952 paper titled "The Chemical Basis of Morphogenesis" which describes how patterns in nature, such as stripes and spots, can arise naturally and autonomously from a homogeneous, uniform state.
Typical mixing pattern for many lakes, caused by the fact that water is less dense at the freezing point than at 4 Celsius. Lake stratification is stable in summer and winter, becoming unstable in spring and fall when the surface waters cross the 4 Celsius mark. Stable stratifications can become unstable if layers change density.
Hegemonic stability theory (HST) is a theory of international relations, rooted in research from the fields of political science, economics, and history.HST indicates that the international system is more likely to remain stable when a single state is the dominant world power, or hegemon. [1]
Original mapping by John Snow showing the clusters of cholera cases in the London epidemic of 1854, which is a classical case of using human geography. Human geography or anthropogeography is the branch of geography which studies spatial relationships between human communities, cultures, economies, and their interactions with the environment, examples of which include urban sprawl and urban ...
A KH instability rendered visible by clouds, known as fluctus, [2] over Mount Duval in Australia A KH instability on the planet Saturn, formed at the interaction of two bands of the planet's atmosphere Kelvin-Helmholtz billows 500m deep in the Atlantic Ocean Animation of the KH instability, using a second order 2D finite volume scheme
Hydrodynamics simulation of the Rayleigh–Taylor instability [3] Unstable flow structure generated from the collision of two impinging jets.. Fluid instabilities occur in liquids, gases and plasmas, and are often characterized by the shape that form; they are studied in fluid dynamics and magnetohydrodynamics.
Rice terraces located in Mù Cang Chải district, Yên Bái province, Vietnam Integrated geography (also referred to as integrative geography, [1] environmental geography or human–environment geography) is where the branches of human geography and physical geography overlap to describe and explain the spatial aspects of interactions between human individuals or societies and their natural ...
