"On the reproducibility of microcosm experiments – different community composition in parallel phototrophic biofilm microcosms". The ancient Greek idea of a world soul (e.g., in Plato) animating the universe had as a corollary the idea of the human body as a miniature universe animated by its own soul. Roeselers, Guus Zippel, Barbara Staal, Marc Van Loosdrecht, Mark Muyzer, Gerard (2006). microcosm, (from Greek mikros kosmos, little world), a Western philosophical term designating man as being a little world in which the macrocosm, or universe, is reflected.

Ecological Engineering: An Introduction to Ecotechnology. "Ecological engineering and self-organization". "Diversity peaks at intermediate productivity in a laboratory microcosm".

Kassen, Rees Buckling, Angus Bell, Graham Rainey, Paul B.

"Community assembly in the presence of disturbance: a microcosm experiment".

Biosphere 2 - Controversial project with a 1.27 ha artificial closed ecological system in Oracle, Arizona (USA).

Odum was a pioneer in his use of small closed and open ecosystems in classroom teaching. A Winogradsky column is an example of a microbial microcosm. Microcosm studies can be very useful to study the effects of disturbance or to determine the ecological role of key species. Open or closed microcosms provide an experimental area for ecologists to study natural ecological processes. Microcosms are artificial, simplified ecosystems that are used to simulate and predict the behaviour of natural ecosystems under controlled conditions.

Importantly, the term “word problem” does not necessarily imply that every task that meets the above definition represents a true problem, in the cognitive-psychological sense of the word, for a given student, i.e., a task for which no routine method of solution is available and which therefore requires the activation of.

As such they differ both from bare sums presented in written (e.g., 4 + 5 = ? 5x + 2 = 22) or oral form (e.g., How much is 40 divided by 5? What is the mean of the numbers 12, 17, 17, 18?), as well as from quantitative problems encountered in real life (e.g., Which type of loan should we take? Can I drive home from here without filling the tank?). Word problems are typically defined as verbal descriptions of problem situations wherein one or more questions are raised the answer to which can be obtained by the application of mathematical operations to numerical data available in the problem statement (Verschaffel et al.
