Horace Bénédict De Saussure
Horace Bénédict de Saussure (; 17 February 1740 – 22 January 1799) was a Genevan geologist, meteorologist, physicist, mountaineer and Alpine explorer, often called the founder of alpinism and modern meteorology, and considered to be the first person to build a successful solar oven. Early life and education Horace Bénédict de Saussure was born 17 February 1740, in Conches, near Geneva (''today in Switzerland but then an independent republic''). Saussure's family were Genevan patricians. His father, Nicolas de Saussure, was an agriculturist, agronomist and author. Because his mother was "sickly", Saussure was brought up by his mother's sister and her husband the Genevan naturalist Charles Bonnet, who sparked Horace-Bénédict's early interest in botany. After attending the "Collège" of his hometown, he completed his studies at the Geneva Academy in 1759 with a dissertation on heat (''Dissertatio physica de igne''). Career In 1760, Saussure made the first of nume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Chêne-Bougeries
Chêne-Bougeries is a municipality in the Canton of Geneva, Switzerland. History Chêne-Bougeries is first mentioned in 1270 as ''Quercus''. In 1801 it was mentioned as ''Chêne-les-Bougeries''. Chêne-Bougeries was inhabited for most of its history, and neither the Romans nor the Genevans settled there. An important concern for the Genevans was the leprosy hospital that occupied part of the commune; it is only when this illness was defeated around the 16th century that Chêne-Bougeries really started to develop. During the French Revolution, the territory was occupied by the French. In 1798 the commune was forced to merge with the neighbouring communes of Chêne-Thônex and Chêne-Bourg to create a new entity, the Trois-Chêne. In 1801, however, it was able to regain the autonomous commune status, while Chêne-Thônex and Chêne-Bourg remained unified. In 1816, Chêne-Bougeries, as many of other neighboring communes, became part of a newly Swiss Geneva. Incidentally, Chêne- ...

Hygrometer
A hair tension dial hygrometer with a nonlinear scale. A hygrometer is an instrument that measures humidity: that is, how much water vapor is present. Humidity measurement instruments usually rely on measurements of some other quantities, such as temperature, pressure, mass, and mechanical or electrical changes in a substance as moisture is absorbed. By calibration and calculation, these measured quantities can be used to indicate the humidity. Modern electronic devices use the temperature of condensation (called the dew point), or they sense changes in electrical capacitance or resistance. The maximum amount of water vapor that can be present in a given volume (at saturation) varies greatly with temperature; at low temperatures a lower mass of water per unit volume can remain as vapor than at high temperatures. Thus a change in the temperature changes the relative humidity. A prototype hygrometer was invented by Leonardo da Vinci in 1480. Major improvements occurred during ...

Geneva Academy
Geneva Academy is a private classical Christian school located in Lincoln, Delaware. The school was founded in 2008 by a group of homeschool parents, taking inspiration from Dorothy Sayers essay "The Lost Tools of Learning," as well as Douglas Wilson's books, ''Recovering the Lost Tools of Learning'' and ''The Case for Classical Christian Education''. Geneva Academy follows a traditional education pattern called the ''Trivium''. This pattern consists of three successive stages: grammar, logic (dialectic), and rhetoric Rhetoric is the art of persuasion. It is one of the three ancient arts of discourse ( trivium) along with grammar and logic/ dialectic. As an academic discipline within the humanities, rhetoric aims to study the techniques that speakers or w ....

Charles Bonnet
Charles Bonnet (; 13 March 1720 – 20 May 1793) was a Republic of Geneva, Genevan natural history, naturalist and philosophical methodology, philosophical writer. He is responsible for coining the term ''phyllotaxis'' to describe the arrangement of leaves on a plant. He was among the first to notice parthenogenesis, parthenogenetic reproduction in aphids and established that insects respired through their spiracles. He was among the first to use the term "evolution" in a biological context. Deaf from an early age, he also suffered from failing eyesight and had to make use of assistants in later life to help in his research. Life and work Bonnet was born in Geneva, the son of Pierre Bonnet and Anne-Marie Lullin de Châteauvieux. Although originally from France, the family had been driven into Geneva by religious persecution of Protestants in the 16th century. At age seven he lost his hearing, which pushed him into an interest in the natural world. His schoolmates troubled him du ...

Solar Cooker
A solar cooker is a device which uses the energy of direct sunlight to heat, cook or pasteurize drink and other food materials. Many solar cookers currently in use are relatively inexpensive, low-tech devices, although some are as powerful or as expensive as traditional stoves, and advanced, large scale solar cookers can cook for hundreds of people. Because these cookers use no fuel and cost nothing to operate, many nonprofit organizations are promoting their use worldwide in order to help reduce fuel costs and air pollution, and to help slow down deforestation and desertification. History In ancient times, the use of solar energy was believed to have existed in civilizations amidst the Greeks, Romans and the Chinese, though not for cooking. The first academic description of the principles of a solar cooker is by the Genevan geologist, meteorologist, physicist, and Alpine explorer Horace-Bénédict de Saussure, in 1767. The principle of cooking meals by sunlight was large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Mountaineer
Mountaineering, mountain climbing, or alpinism is a set of outdoor activities that involves ascending mountains. Mountaineering-related activities include traditional outdoor climbing, skiing, and traversing via ferratas that have become sports in their own right. Indoor climbing, sport climbing, and bouldering are also considered variants of mountaineering by some, but are part of a wide group of mountain sports. Unlike most sports, mountaineering lacks widely applied formal rules, regulations, and governance; mountaineers adhere to a large variety of techniques and philosophies (including grading and guidebooks) when climbing mountains. Numerous local alpine clubs support mountaineers by hosting resources and social activities. A federation of alpine clubs, the International Climbing and Mountaineering Federation (UIAA), is the International Olympic Committee-recognized world organization for mountaineering and climbing. The consequences of mountaineering on the natural env ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
