Teylers Oval Room
The Oval Room in the Teylers Museum was the first part of the museum (though it was not called a museum yet) that was opened in 1784. It could be entered through the garden of the fundatiehuis, the former home of Pieter Teyler van der Hulst. The building has an oval shape built around its centerpiece, a mineralogical cabinet. The Oval Room consists of two floors; the ground floor with its display cabinets and a gallery of books that connects to the Teylers Library. On top of the room, on the roof, the astronomical observatory used to be a landmark that could be seen for miles along the river Spaarne. The gallery and observatory are longer accessible to the public, though the gallery can be seen from the ground floor. History In 1779, the board of the Teylers Foundation (''Teylers Stichting'') commissioned Leendert Viervant, the Amsterdam-based architect of amongst others the church of Ouderkerk aan den Amstel [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weesp
Weesp () is a city, an urban area in the municipality of Amsterdam and a former municipality in the province of North Holland, Netherlands. It had a population of in . It lies on the river Vecht and next to the Amsterdam–Rhine Canal in an area called the Vechtstreek. On 1 June 2019 the civil service offices of the municipality of Weesp merged with those of the municipality of Amsterdam in preparation of the merger of the two municipalities, which was finalized on 24 March 2022. History Until the early Middle Ages the region around Weesp was an uninhabited peat bog. Weesp (Wesopa in Latin documents) was granted city rights in 1355 and celebrated its 650th anniversary as a city in 2005. From the late Middle Ages, the river Vecht was a defensive line for the County of Holland and it remained a military defensive line until the Second World War. Weesp was strongly fortified, more than its size would justify; for most of its history it had a few thousand inhabitants. The def ...

George Adams (scientist, Died 1795)
George Adams the younger (1750–1795) was an English scientist, optician and scientific writer. He was mathematical instrument maker to King George III of Great Britain, succeeding his father George Adams in the post. He also made globes. Around 1770, Adams invented the lucernal microscope, a type of projection microscope where the image is projected on a screen by a large oil lamp, as to make it easier to draw or trace the image. In politics Adams was a Tory, and as such was received with favour at court by George III. He died 14 August 1795, at Southampton, and was succeeded in his business and in the post of mathematical instrument maker to the king by his brother, Dudley Adams. Works Adams wrote elementary scientific works, and on the use of mathematical instruments. He often combined religious with a scientific content, against, according to the ''Gentleman's Magazine ''The Gentleman's Magazine'' was a monthly magazine founded in London, England, by Edward Cave i ...

The specimen was cut off from the highest findable piece of exposed rock of the Rocher de la Tournette, high on the snow covered summit ridge of the Mont Blanc on 3 August 1787, during one of the first climbs of the mountain by the Swiss scientific pioneer Horace Bénédict de Saussure.Website of the Teylers Museum on the top of the Mont Blanc The climb The climb was the second known to reach the top of Mont Blanc after and |
Electrostatic Generator
An electrostatic generator, or electrostatic machine, is an electrical generator that produces '' static electricity'', or electricity at high voltage and low continuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained merely an interesting and mystifying phenomenon, without a theory to explain its behavior and often confused with magnetism. By the end of the 17th century, researchers had developed practical means of generating electricity by friction, but the development of electrostatic machines did not begin in earnest until the 18th century, when they became fundamental instruments in the studies about the new science of electricity. Electrostatic generators operate by using manual (or other) power to transform mechanical work into electric energy, or using electric currents. Manual electrostatic generators develop electrostatic charges of opposite signs rendered to two conductors, using only electric forces ...

Oak Wood
An oak is a tree or shrub in the genus ''Quercus'' (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably ''Lithocarpus'' (stone oaks), as well as in those of unrelated species such as '' Grevillea robusta'' (silky oaks) and the Casuarinaceae (she-oaks). The genus ''Quercus'' is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America has the largest number of oak species, with approximately 160 species in Mexico of which 109 are endemic and about 90 in the United States. The second greatest area of oak diversity is China, with approximately 100 species. Description Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. Ma ...

Pine Wood
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or trinomials) recognized by the ACS. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine located in southern Oregon's Rogue River-Si ...
