Old Higher Lighthouse
The Old Higher Lighthouse is a disused 19th century lighthouse on the Isle of Portland, Dorset, southern England. It is located at Branscombe Hill on the west side of Portland, overlooking Portland Bill. The lighthouse is Grade II Listed. History The surrounding coast of Portland, namely Portland Bill and Chesil Beach, have been notorious for the many vessels that became shipwrecked in the area over the centuries. After years of local petitions to Trinity House, the organisation agreed for a lighthouse to be built at Portland Bill. George I granted the patent in 1716. That year, it was announced that Trinity House had 'caus'd to be erected two round Light-Houses of Stone upon Portland, in the County of Dorset, distant about two Thirds of a Mile from the Bill of Portland'. This one was built at Branscombe Hill, and the other, the Old Lower Lighthouse, on lower land. Designed as leading lights to guide ships between Portland Race and the Shambles sandbank, they shone out for the fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isle Of Portland
An isle is an island, land surrounded by water. The term is very common in British English. However, there is no clear agreement on what makes an island an isle or its difference, so they are considered synonyms. Isle may refer to: Geography * Isle (river), a river in France * Isle, Haute-Vienne, a commune of the Haute-Vienne ''département'' in France * Isle, Minnesota, a small city in the United States * River Isle, a river in England Arts, entertainment, and media * ''Interdisciplinary Studies in Literature and Environment'' (or ''ISLE''), a journal published by Oxford University Press for the Association for the Study of Literature and Environment *''The Isle'', 2017 film with Conleth Hill * ''The Isle'', a 2000 South Korean film directed by Kim Ki-duk * ''Isle'' (album) Other uses * International Society for the Linguistics of English (ISLE), a learned society of linguists See also * Aisle An aisle is, in general, a space for walking with rows of non-walking spaces o ...

Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The ''catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances. Description The Fresnel lens redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouses Of The English Channel
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marie Stopes
Marie Charlotte Carmichael Stopes (15 October 1880 – 2 October 1958) was a British author, palaeobotanist and campaigner for eugenics and women's rights. She made significant contributions to plant palaeontology and coal classification, and was the first female academic on the faculty of the University of Manchester. With her second husband, Humphrey Verdon Roe, Stopes founded the first birth control clinic in Britain. Stopes edited the newsletter ''Birth Control News'', which gave explicit practical advice. Her sex manual ''Married Love'' (1918) was controversial and influential, and brought the subject of birth control into wide public discourse. Stopes publicly opposed abortion, arguing that the prevention of conception was all that was needed, though her actions in private were at odds with her public pronouncements. As a supporter of eugenics one of her stated aims was "to furnish security from conception to those who are racially diseased". In reaction to this at ...

Portland Museum, Dorset
Portland Museum is a museum on the Isle of Portland in Dorset, southern England. It is located at the southern end of the hamlet of Wakeham. The museum is housed in two 17th-century thatched cottages, which have both been Grade II Listed since 1951. One of the museum's cottages, Avice's Cottage, is featured in Thomas Hardy's 1897 novel ''The Well-Beloved'', as the home of three generations of "Avices" - the novel's heroines. Portland Museum was founded by Marie Stopes, who purchased the museum's two cottages, then derelict, in 1929. She then donated them to Portland as a museum which opened in 1930. Stopes was the first honorary curator and continued her association with the museum until her death in 1958. Features The museum has four distinct themes; the history of Portland stone, the Jurassic Coast The Jurassic Coast is a World Heritage Site on the English Channel coast of southern England.

Eugenics
Eugenics ( ; ) is a fringe set of beliefs and practices that aim to improve the genetic quality of a human population. Historically, eugenicists have attempted to alter human gene pools by excluding people and groups judged to be inferior or promoting those judged to be superior. In recent years, the term has seen a revival in bioethical discussions on the usage of new technologies such as CRISPR and genetic screening, with a heated debate on whether these technologies should be called eugenics or not. The concept predates the term; Plato suggested applying the principles of selective breeding to humans around 400 BC. Early advocates of eugenics in the 19th century regarded it as a way of improving groups of people. In contemporary usage, the term ''eugenics'' is closely associated with scientific racism. Modern bioethicists who advocate new eugenics characterize it as a way of enhancing individual traits, regardless of group membership. While eugenic principles have be ...
