Carl Ritter
Carl Ritter (August 7, 1779September 28, 1859) was a German geographer. Along with Alexander von Humboldt, he is considered one of the founders of modern geography. From 1825 until his death, he occupied the first chair in geography at the University of Berlin. Biography Carl Ritter was born in Quedlinburg, one of the six children of a well-respected doctor, F. W. Ritter. Ritter's father died when he was two. At the age of five, he was enrolled in the Schnepfenthal Salzmann School, a school focused on the study of nature (apparently influenced by Jean-Jacques Rousseau's writings on children's education). This experience would influence Ritter throughout his life, as he retained an interest in new educational modes, including those of Johann Heinrich Pestalozzi. Indeed, much of Ritter's writing was based on Pestalozzi's three stages in teaching: the acquisition of the material, the general comparison of material, and the establishment of a general system.

Physiology
Physiology (; ) is the scientific study of functions and mechanisms in a living system. As a sub-discipline of biology, physiology focuses on how organisms, organ systems, individual organs, cells, and biomolecules carry out the chemical and physical functions in a living system. According to the classes of organisms, the field can be divided into medical physiology, animal physiology, plant physiology, cell physiology, and comparative physiology. Central to physiological functioning are biophysical and biochemical processes, homeostatic control mechanisms, and communication between cells. ''Physiological state'' is the condition of normal function. In contrast, ''pathological state'' refers to abnormal conditions, including human diseases. The Nobel Prize in Physiology or Medicine is awarded by the Royal Swedish Academy of Sciences for exceptional scientific achievements in physiology related to the field of medicine. Foundations Cells Although there are differ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meteorology
Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century. The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data. It was not until after the elucidation of the laws of physics, and more particularly in the latter half of the 20th century the development of the computer (allowing for the automated solution of a great many modelling equations) that significant breakthroughs in weather forecasting were achieved. An important branch of weather forecasting is marine weather forecasting as it relates to maritime and coastal safety, in which weather effects also include atmospheric interactions with large bodies of water. Meteorological pheno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrography
Hydrography is the branch of applied sciences which deals with the measurement and description of the physical features of oceans, seas, coastal areas, lakes and rivers, as well as with the prediction of their change over time, for the primary purpose of safety of navigation and in support of all other marine activities, including economic development, security and defense, scientific research, and environmental protection. History The origins of hydrography lay in the making of charts to aid navigation, by individual mariners as they navigated into new waters. These were usually the private property, even closely held secrets, of individuals who used them for commercial or military advantage. As transoceanic trade and exploration increased, hydrographic surveys started to be carried out as an exercise in their own right, and the commissioning of surveys was increasingly done by governments and special hydrographic offices. National organizations, particularly navies, realized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction Product (chemistry), products. At a certain point in the combustion reaction, called the ignition point, flames are produced. The ''flame'' is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce Plasma (physics), plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's Intensity (heat transfer), intensity will be different. Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Its negative effects include hazard to life and pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmosphere Of Earth
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in ...

Water
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of 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 co ...

Ritter Range
The Ritter Range is a small mountain range within California's Sierra Nevada. Most of the mountain range lies within the Ansel Adams Wilderness. The John Muir Trail passes by many lakes within the Ritter Range. The most prominent peaks of the Ritter Range are Mount Ritter, at 13,143 feet, Banner Peak, at 12,936 feet, Rodgers Peak, and the Minarets, a group of sharp peaks south of Mt. Ritter. Thousand Island Lake, Ediza Lake, Garnet Lake, Lake Catherine, Minaret Lake, Cecile Lake, and Shadow Lake all lie within the Ritter Range, and are accessible by trail. The range is named for Carl Ritter, who had been a teacher of Josiah Whitney when he was a student in Berlin in the 1840s." The Ritter Range, near the Minarets and Minaret Lake, was the site of the plane crash of Steve Fossett in 2007.

Johann Christoph Friedrich GutsMuths
Johann Christoph Friedrich GutsMuths, also called Guts Muth or Gutsmuths (9 August 1759 – 21 May 1839), was a teacher and educator in Germany, and is especially known for his role in the development of physical education. He is thought of as the "grandfather of gymnastics" – the "father" being Friedrich Ludwig Jahn. GutsMuths introduced systematic physical exercise into the school curriculum, and he developed the basic principles of artistic gymnastics. Biography He was born in Quedlinburg. He attended the University of Halle from 1778 to 1782, where he studied pedagogy. Sometime after 1785 while a private tutor in Schnepfenthal (where he remained his entire life) he was appointed as a teacher, and it was there he taught gymnastics supervised by Salzmann. In 1793, GutsMuths published , the first systematic coursebook on gymnastics. His literary output on both moral and physical education continued upwards of twenty-five years after the production of his seminal work . ...
