  2. Pierre Perrault (scientist) - Wikipedia

    en.wikipedia.org/wiki/Pierre_Perrault_(scientist)

    With a series of experiments, Perrault showed that rain does not penetrate the soil beyond about 2 feet (0.61 m). Thus, most of the rain that falls does not go into springs. Perrault developed the theory of the hydrologic cycle, correctly accounting for the roles of evaporation, transpiration, throughflow, and surface runoff. Notes

  3. Prism correction - Wikipedia

    en.wikipedia.org/wiki/Prism_correction

    Prism dioptres. Prism correction is commonly specified in prism dioptres, a unit of angular measurement that is loosely related to the dioptre. Prism dioptres are represented by the Greek symbol delta (Δ) in superscript. A prism of power 1 Δ would produce 1 unit of displacement for an object held 100 units from the prism. [2]

  4. Biotic pump - Wikipedia

    en.wikipedia.org/wiki/Biotic_pump

    The biotic pump theory may be able to help us better understand the role forests have on the water cycle. The biotic pump is a theoretical concept that shows how forests create and control winds coming up from the ocean and in doing so bring water to the forests further inland.

  5. Water cycle - Wikipedia

    en.wikipedia.org/wiki/Water_cycle

    The water cycle describes the processes that drive the movement of water throughout the hydrosphere. However, much more water is "in storage" (or in "pools") for long periods of time than is actually moving through the cycle. The storehouses for the vast majority of all water on Earth are the oceans.

  6. Stephan Riess - Wikipedia

    en.wikipedia.org/wiki/Stephan_Riess

    Stephan Riess. Stephan Ernst Riess (26 December 1898 – 17 December 1985) was a German geochemist, mineralogist, geo-hydrologist and dowser [1] who immigrated to the US after World War I. He worked for over five decades, located over 800 water wells, and studied the concept of earth-generated water, also known as "new water" or "primary water".

  9. Prism (optics) - Wikipedia

    en.wikipedia.org/wiki/Prism_(optics)

    Prism spectacles with a single prism perform a relative displacement of the two eyes, thereby correcting eso-, exo, hyper- or hypotropia. In contrast, spectacles with prisms of equal power for both eyes, called yoked prisms (also: conjugate prisms, ambient lenses or performance glasses) shift the visual field of both eyes to the same extent.

  10. Oxygen-evolving complex - Wikipedia

    en.wikipedia.org/wiki/Oxygen-evolving_complex

    Based on a widely accepted theory from 1970 by Kok, the complex can exist in 5 states, denoted S 0 to S 4, with S 0 the most reduced and S 4 the most oxidized. Photons trapped by photosystem II move the system from state S 0 to S 4. S 4 is unstable and reacts with water producing free oxygen.

  11. Open system (systems theory) - Wikipedia

    en.wikipedia.org/wiki/Open_system_(systems_theory)

    Open system (systems theory) An open system is a system that has external interactions. Such interactions can take the form of information, energy, or material transfers into or out of the system boundary, depending on the discipline which defines the concept. An open system is contrasted with the concept of an isolated system which exchanges ...
