Theodor Schwenk (8 October 1910, Schwäbisch Gmünd – 29 September 1986, Filderstadt) was an anthroposophist, an engineer and a pioneering water researcher who founded the Institute for Flow. He is most well known for his book Sensitive Chaos which explores subtle patterns and phenomenon of water, air and their relationship to biological forms. The narrative of the book is in the tradition of Goethe and Rudolf Steiner, viewing nature as ruled by a single unifying principle which is apparent in all movement and form.
Schwäbisch Gmünd is a town in the eastern part of the German state of Baden-Württemberg. With a population of around 60,000, the town is the second largest in the Ostalb district and the whole East Württemberg region after Aalen. The town is a Große Kreisstadt since 1956, i.e. a chief town under district administration; it was the administrative capital of its own rural district until the local government reorganisation on 1 January 1973.
Filderstadt is a town in the district of Esslingen in Baden-Württemberg in southern Germany. It is located approximately 13 km south of Stuttgart.
Anthroposophy is a philosophy founded by the 19th century esotericist Rudolf Steiner that postulates the existence of an objective, intellectually comprehensible spiritual world, accessible to human experience. Followers of anthroposophy aim to develop mental faculties of spiritual discovery through a mode of thought independent of sensory experience. They also aim to present their ideas in a manner verifiable by rational discourse and specifically seek a precision and clarity in studying the spiritual world mirroring that obtained by natural historians in investigations of the physical world.

In chemistry, an alcohol is any organic compound in which the hydroxyl functional group (–OH) is bound to a carbon. The term alcohol originally referred to the primary alcohol ethanol, which is used as a drug and is the main alcohol present in alcoholic beverages. An important class of alcohols, of which methanol and ethanol are the simplest members, includes all compounds for which the general formula is CnH2n+1OH. It is these simple monoalcohols that are the subject of this article.
A disaccharide is the sugar formed when two monosaccharides are joined by glycosidic linkage. Like monosaccharides, disaccharides are soluble in water. Three common examples are sucrose, lactose, and maltose.
An emulsion is a mixture of two or more liquids that are normally immiscible. Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms colloid and emulsion are sometimes used interchangeably, emulsion should be used when both phases, dispersed and continuous, are liquids. In an emulsion, one liquid is dispersed in the other. Examples of emulsions include vinaigrettes, homogenized milk, and some cutting fluids for metal working.
Nature, in the broadest sense, is the natural, physical, or material world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena.
In chemistry, a solution is a special type of homogeneous mixture composed of two or more substances. The term aqueous solution is when one of the solvents is water. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent. The mixing process of a solution happens at a scale where the effects of chemical polarity are involved, resulting in interactions that are specific to solvation. The solution assumes the phase of the solvent when the solvent is the larger fraction of the mixture, as is commonly the case. The concentration of a solute in a solution is the mass of that solute expressed as a percentage of the mass of the whole solution.
Spaghetti is a long, thin, solid, cylindrical pasta. Spaghettoni is a thicker form of spaghetti, while capellini is a very thin spaghetti. It is a staple food of traditional Italian cuisine. Like other pasta, spaghetti is made of milled wheat and water and sometimes enriched with vitamins and minerals. Authentic Italian spaghetti is made from durum wheat semolina, but elsewhere it may be made with other kinds of flour. Typically the pasta is white because refined flour is used, but whole wheat flour may be added.
In thermodynamics, the triple point of a substance is the temperature and pressure at which the three phases of that substance coexist in thermodynamic equilibrium. It is that temperature and pressure at which the sublimation curve, fusion curve and the vaporisation curve meet. For example, the triple point of mercury occurs at a temperature of −38.83440 °C and a pressure of 0.2 mPa.
The Tigris is the eastern member of the two great rivers that define Mesopotamia, the other being the Euphrates. The river flows south from the mountains of southeastern Turkey through Iraq and empties itself into the Persian Gulf.
Water is a transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. It is vital for all known forms of life, even though it provides no calories or organic nutrients. Its chemical formula is H2O, meaning that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. Water is the name of the liquid state of H2O at [[standard ambient temperature and pressure]]. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds are formed from suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water moves continually through the water cycle of evaporation, transpiration (evapotranspiration), condensation, precipitation, and runoff, usually reaching the sea.
A gill is a respiratory organ found in many aquatic organisms that extracts dissolved oxygen from water and excretes carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia is the zoologists' name for gills.
Xylem is one of the two types of transport tissue in vascular plants, phloem being the other. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients. The word "xylem" is derived from the Greek word ξύλον (xylon), meaning "wood"; the best-known xylem tissue is wood, though it is found throughout a plant. The term was introduced by Carl Nägeli in 1858.
A waterfall is an area where water flows over a vertical drop or a series of steep drops in the course of a stream or river. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf.
Hygroscopy is the phenomenon of attracting and holding water molecules from the surrounding environment, which is usually at normal or room temperature. This is achieved through either absorption or adsorption with the adsorbing substance becoming physically changed somewhat. This could be an increase in volume, boiling point, viscosity, or other physical characteristic or property of the substance, as water molecules can become suspended between the substance's molecules in the process.
Kaveri, also referred as Ponni, is an Indian river flowing through the states of Karnataka and Tamil Nadu. It is the third largest after Godavari and Krishna in south India and the largest in Tamil Nadu which on its course, bisects the state into North and South. Originating in the foothills of Western Ghats at Talakaveri, Kodagu in Karnataka it flows generally south and east through Karnataka and Tamil Nadu and across the southern Deccan plateau through the southeastern lowlands, emptying into the Bay of Bengal through two principal mouths in Poompuhar, Tamil Nadu. Amongst the river valleys, the Kaveri delta forms one of the most fertile regions in the country.
The heating value of a substance, usually a fuel or food, is the amount of heat released during the combustion of a specified amount of it.
A root hair, or absorbent hair, the rhizoid of a vascular plant, is a tubular outgrowth of a trichoblast, a hair-forming cell on the epidermis of a plant root. As they are lateral extensions of a single cell and only rarely branched, they are visible to the naked eye and light microscope. They are found only in the region of maturation of the root. Just prior to, and during, root hair cell development, there is elevated phosphorylase activity.
Hydroman is a fictional superhero character who first appeared in comic books from Eastern Color Printing in 1940; not to be confused with the Spider-Man villain Hydro-Man.
Season one of Avatar: The Last Airbender, an American animated television series produced by Nickelodeon Studios, aired 20 episodes from February 21, 2005 to December 2, 2005. The series was created by Michael Dante DiMartino and Bryan Konietzko, and starred Zach Tyler Eisen, Mae Whitman, Jack DeSena, Dante Basco, Dee Bradley Baker, Mako Iwamatsu and Jason Isaacs as the main character voices.
Isopropyl alcohol (IUPAC name propan-2-ol; commonly called isopropanol or 2-propanol) is a compound with the chemical formula CH3CHOHCH3. It is a colorless, flammable chemical compound with a strong odor. As an isopropyl group linked to a hydroxyl group, it is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms. It is a structural isomer of 1-propanol and ethyl methyl ether.
Water is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue. It is by far the most studied chemical compound and is described as the "universal solvent" and the "solvent of life". It is the most abundant substance on Earth and the only common substance to exist as a solid, liquid, and gas on Earth's surface. It is also the third most abundant molecule in the universe.
