Anna Wulff
Anna Wulff (13 August 1874, Frederiksberg — 7 January 1935, Søllerød) was a pioneering Danish kindergarten teacher. On the basis of experience she gained both from her mother and from a course at the Friedrich Fröbel, Fröbel Foundation in Dresden, in 1897 she began training teachers to work in kindergartens in Denmark and in 1906 established Frøbelhøjskolen, a folk high school specializing in training kindergarten teachers. From 1915, she headed the Folkebørnehave på Christianshavn (Christianhavn Folk Kindergarten). Committed to Christian principles, Wulff ran her kindergarten as an extension to home-based parental upbringing, strengthening the children's character through close human relationships, activities promoting self-reliance, and play. Early life and education Born in the Frederiksberg district of Copenhagen on 13 August 1874, Anna Wulff was the daughter of German parents who had emigrated to Denmark.

Potassium
Potassium is the chemical element with the symbol K (from Neo-Latin ''kalium'') and atomic number19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, from which its name derives. In the periodic table, potassium is one of the alkali metals, all of which have a single valence electron in the outer electron shell, that is easily removed to create an ion with a positive charge – a cation, that combines with anions to form salts. Potassium in nature occurs only in ionic salts. Elemental potassium reacts vigorously with water, generating sufficient heat to ignite hydrogen emitted in the reaction, and burning with a lilac- colored flame. It is found dissolved in sea water (which is 0.04% potassium by weight), and occurs in many minerals such as orthoclase, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wulff (comics)
''X-Nation 2099'' was a comic book series created by Marvel Comics for their Marvel 2099 imprint. It depicts the course of events in a team of young mutants' lives. The series only lasted six issues. Fictional team biography In the year 2099, Victor Von Doom approached Cerebra of the X-Men with a proposition. He told her that through a mathematical probability program he had deduced that there would be a mutant Messiah in the next generation, and he offered her the position of finding it for him. Cerebra agreed and left the X-Men in search of this figure who would lead all of mutantkind into a golden age. She began finding candidates and bringing them to the Xavier Center, which was watched over by a militant sect of nuns named the Sisters of the Howling Commandments. She was aided, albeit unwillingly, by Morphine Somers, former Minister of Humanity and interim liaison to Halo City while Doom was still President. The group's first adventure, like most in the short run of the se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wulff Net
In mathematics, a stereographic projection is a perspective projection of the sphere, through a specific point on the sphere (the ''pole'' or ''center of projection''), onto a plane (the ''projection plane'') perpendicular to the diameter through the point. It is a smooth, bijective function from the entire sphere except the center of projection to the entire plane. It maps circles on the sphere to circles or lines on the plane, and is conformal, meaning that it preserves angles at which curves meet and thus locally approximately preserves shapes. It is neither isometric (distance preserving) nor equiareal (area preserving). The stereographic projection gives a way to represent a sphere by a plane. The metric induced by the inverse stereographic projection from the plane to the sphere defines a geodesic distance between points in the plane equal to the spherical distance between the spherical points they represent. A two-dimensional coordinate system on the stereographi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulfur
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere The greatest commercial use of the element is the production o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxygen
Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is Earth's most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula . Diatomic oxygen gas currently constitutes 20.95% of the Earth's atmosphere, though this has changed considerably over long periods of time. Oxygen makes up almost half of the Earth's crust in the form of oxides.Atkins, P.; Jones, L.; Laverman, L. (2016).''Chemical Principles'', 7th edition. Freeman. Many major classes of organic molecules in living organisms contain oxygen atoms, such as proteins, nucleic acids, carbohydrates, and fats, as ...

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Sodium
Sodium is a chemical element with the symbol Na (from Latin ''natrium'') and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23Na. The free metal does not occur in nature, and must be prepared from compounds. Sodium is the sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars, sodalite, and halite (NaCl). Many salts of sodium are highly water-soluble: sodium ions have been leached by the action of water from the Earth's minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans. Sodium was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Among many other useful sodium compounds, sodium hydroxide (lye) is used in soap manufacture, and sodium chloride (edible salt) is a de-icing agent and a nutrient for animals including h ...

Wulffite
Wulffite is an alkali copper sulfate mineral with the chemical formula K3 Na Cu4 O2( S O4)4, in the sulfate category of minerals. It was recently discovered in Kamchatka, Russia at the Tolbachik volcano in 2012. It was named for Russian crystallographer Georgiy Viktorovich Wulff, a renowned expert who furthered X-ray diffraction and interference. Wullfite shares many properties with parawulffite, which was found in the same area just with slightly different chemical composition. Occurrence Wulffite is a volcanic, or fumarolic, mineral which forms in or near volcanic activity. It has been recorded as associated with hematite, langbeinite, calciolangbeinite, arcanite, krasheninnikovite, lammerite, labberite-β, johillerite, bradaczekite, urusovite, fluoborite, gahnite, orthoclase, and fluorophlogopite. Wulffite has been found to reside about a meter down in between layers of basalt scoria and small 2-inch volcanic plutons, otherwise known as volcanic bombs, where most of th ...
