Source–sink dynamics is a theoretical model used by ecologists to describe how variation in habitat quality may affect the population growth or decline of organisms.. Since quality is likely to vary among patches of habitat, it is important to consider how a low quality patch might affect a population.
From left to right: a field with a source, a field with a sink, a field without either. In the physical sciences, engineering and mathematics, sources and sinks is an analogy used to describe properties of vector fields. It generalizes the idea of fluid sources and sinks (like the faucet and drain of a bathtub) across different scientific ...
Source-sink models describe a framework in which dispersal and environmental heterogeneity interact to determine local and regional abundance and composition. This framework is derived from the metapopulation ecology term describing source–sink dynamics at the population level. High levels of dispersal among habitat patches allow populations ...
Boris Karloff in James Whale's 1931 film Frankenstein, based on Mary Shelley's 1818 novel.The monster is created by an unorthodox biology experiment.. Biology appears in fiction, especially but not only in science fiction, both in the shape of real aspects of the science, used as themes or plot devices, and in the form of fictional elements, whether fictional extensions or applications of ...
Science Fiction Literature through History: An Encyclopedia is a 2021 reference work written by science fiction scholar Gary Westfahl and published by ABC-Clio/Greenwood.The book contains eight essays on the history of science fiction, eleven thematic essays on how different topics relate to science fiction, and 250 entries on various science fiction subgenres, authors, works, and motifs.
While current sources or sinks are abstract elements used for analysis, generally they have physical counterparts in real-world applications; e.g. the anode or cathode in a battery. In all cases, each of the opposing terms (source or sink) may refer to the same object, depending on the perspective of the observer and the sign convention being ...
Science fiction poetry's main sources are the sciences and the literary movement of science fiction prose. [9]Scientifically-informed verse, sometimes termed poetry of science, is a branch that has either scientists and their work or scientific phenomena as its primary focus; it may also use scientific jargon as metaphor.

The co-editor of the science fiction journal Extrapolation and a professor of English at the University of Georgia, Isaiah Lavender III, notes the usefulness of the dictionary for academic analysis of issues, saying "Having these origin dates in mind can help a student or scholar build a framework to analyze something like the concept of the ...
