Thereza Dillwyn Llewelyn
Thereza Dillwyn Llewelyn (1834 – 21 February 1926) was a Welsh astronomer and pioneer in scientific photography. Biography The eldest of six children, Llewelyn was born to photographer and botanist John Dillwyn Llewelyn and Emma Thomasina Talbot at Penllergare House in Glamorganshire. Along with her parents, her extended family were active in the fields of science in photography, including her mother's cousin the photographer Henry Fox Talbot and her aunt, Mary Dillwyn, one of earliest female photographers in Wales. Llewelyn developed an interest in photography and astronomy, although both were uncommon endeavours for women in the Victorian era. See pages 474–476. Her cousins were the sisters novelist and industrialist Amy Dillwyn and the lepidopterist Mary De la Beche Nicholl. Llewelyn married Nevil Story-Maskelyne, a professor of mineralogy at Oxford University, on 29 June 1858. Through him, she began a correspondence with Charles Darwin.

British Science Association
The British Science Association (BSA) is a charity and learned society founded in 1831 to aid in the promotion and development of science. Until 2009 it was known as the British Association for the Advancement of Science (BA). The current Chief Executive is Katherine Mathieson. The BSA's mission is to get more people engaged in the field of science by coordinating, delivering, and overseeing different projects that are suited to achieve these goals. The BSA "envisions a society in which a diverse group of people can learn and apply the sciences in which they learn." and is managed by a professional staff located at their Head Office in the Wellcome Wolfson Building. The BSA offers a wide variety of activities and events that both recognize and encourage people to be involved in science. These include the British Science Festival, British Science Week, the CREST Awards, Huxley Summit, Media Fellowships Scheme, along with regional and local events. History Foundation The Asso ...

Snow
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astrophotography
Astrophotography, also known as astronomical imaging, is the photography or imaging of astronomical objects, celestial events, or areas of the night sky. The first photograph of an astronomical object (the Moon) was taken in 1840, but it was not until the late 19th century that advances in technology allowed for detailed stellar photography. Besides being able to record the details of extended objects such as the Moon, Sun, and planets, modern astrophotography has the ability to image objects invisible to the human eye such as dim stars, nebulae, and galaxies. This is done by long time exposure since both film and digital cameras can accumulate and sum photons over these long periods of time. Photography using extended exposure-times revolutionized the field of professional astronomical research, recording hundreds of thousands of new stars, and nebulae invisible to the human eye. Specialized and ever-larger optical telescopes were constructed as essentially big cameras to rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Society For The History Of Astronomy
The Society for the History of Astronomy is an organisation based in the United Kingdom that promotes research into the history of astronomy. It publishes a research journal called ''The Antiquarian Astronomer'' and a regular ''Bulletin''. The society The Society for the History of Astronomy was founded in 2002 to promote the study of the history of astronomy by hosting talks by members and publishing new research into the field. One main objective was to encourage research into past astronomers who have previously been neglected within the history of science. Some of its members are professional historians of science but most are amateur historians. The honorary president is Dr Allan Chapman of Wadham College, Oxford. The honorary vice-presidents are Emily Winterburn (who was chair at the time of foundation) and Prof. Mike Edmunds. Previous vice-presidents have included Sir Patrick Moore, Sir Arnold Wolfendale, FRS, and Dr Michael Hoskin. The society hosts several one-day ...

Penllergare Valley Woods
Penllergare is a country park in Wales. It was the estate of John Dillwyn Llewelyn adjacent to what is now the village of Penllergaer, Swansea. Although the names are similar, the village of Penllergaer grew up as a separate entity from the Penllergare estate. The park is listed on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales. History At the height of its prosperity in the nineteenth and early twentieth centuries, the Penllergare estate, on the north-west fringe of Swansea, was one of the great gardens of Britain. Its main creator was John Dillwyn Llewelyn (1810–82), a man as distinguished for his contribution to landscape design and horticulture, as for his scientific experiments and pioneering photography. Penllergare provided inspiration for the expression of Dillwyn-Llewellyn's talents. Taking in the adjacent estate of Nydfwch and based on the work of his father, Lewis Weston Dillwyn, John exploited the natural beauty of the site ...

Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
