Margaret Lindsay Huggins
Margaret Lindsay, Lady Huggins (14 August 1848, in Dublin – 24 March 1915, in London), born Margaret Lindsay Murray, was an Irish-English scientific investigator and astronomer. With her husband William Huggins she was a pioneer in the field of spectroscopy and co-wrote the ''Atlas of Representative Stellar Spectra'' (1899). Family and early life Margaret Lindsay Huggins was part of a family of four. She had a brother, Robert Douglas. Her parents were John Murray and Helen Lindsay. Her father was a solicitor, who attended Edinburgh Academy. Margaret's younger brother by three years, Robert Douglas, attended Edinburgh Academy at the age of twelve, and then attended further education in Trinity College, Dublin in his later years. The family home was a Georgian style townhouse, at 23 Longford Terrace in Kingstown (present-day Dún Laoghaire). Margaret's grandfather, Robert Murray, was a very important figure in her life. He was a wealthy officer at the Bank of Ireland but als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Margaret Lindsay Huggins00
Margaret is a female first name, derived via French () and Latin () from grc, μαργαρίτης () meaning "pearl". The Greek is borrowed from Persian. Margaret has been an English name since the 11th century, and remained popular throughout the Middle Ages. It became less popular between the 16th century and 18th century, but became more common again after this period, becoming the second-most popular female name in the United States in 1903. Since this time, it has become less common, but was still the ninth-most common name for women of all ages in the United States as of the 1990 census. Margaret has many diminutive forms in many different languages, including Maggie, Madge, Daisy, Margarete, Marge, Margo, Margie, Marjorie, Meg, Megan, Rita, Greta, Gretchen, and Peggy.

John Herschel
Sir John Frederick William Herschel, 1st Baronet (; 7 March 1792 – 11 May 1871) was an English polymath active as a mathematician, astronomer, chemist, inventor, experimental photographer who invented the blueprint and did botanical work. Herschel originated the use of the Julian day system in astronomy. He named seven moons of Saturn and four moons of Uranus – the seventh planet, discovered by his father Sir William Herschel. He made many contributions to the science of photography, and investigated colour blindness and the chemical power of ultraviolet rays. His ''Preliminary Discourse'' (1831), which advocated an inductive approach to scientific experiment and theory-building, was an important contribution to the philosophy of science. Early life and work on astronomy Herschel was born in Slough, Buckinghamshire, the son of Mary Baldwin and astronomer William Herschel. He was the nephew of astronomer Caroline Herschel. He studied shortly at Eton College an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Herschel
Frederick William Herschel (; german: Friedrich Wilhelm Herschel; 15 November 1738 – 25 August 1822) was a German-born British astronomer and composer. He frequently collaborated with his younger sister and fellow astronomer Caroline Herschel (1750–1848). Born in the Electorate of Hanover, William Herschel followed his father into the military band of Hanover, before emigrating to Great Britain in 1757 at the age of nineteen. Herschel constructed his first large telescope in 1774, after which he spent nine years carrying out sky surveys to investigate double stars. Herschel published catalogues of nebulae in 1802 (2,500 objects) and in 1820 (5,000 objects). The resolving power of the Herschel telescopes revealed that many objects called nebulae in the Messier catalogue were actually clusters of stars. On 13 March 1781 while making observations he made note of a new object in the constellation of Gemini. This would, after several weeks of verification and consultation ...

Richard Proctor
Richard Anthony Proctor (23 March 1837 – 12 September 1888) was an English astronomer. He is best remembered for having produced one of the earliest maps of Mars in 1867 from 27 drawings by the English observer William Rutter Dawes. His map was later superseded by those of Giovanni Schiaparelli and Eugène Antoniadi and his nomenclature was dropped (for instance, his "Kaiser Sea" became Syrtis Major Planum). He used old drawings of Mars dating back to 1666 to try to determine the sidereal day of Mars. His final estimate, in 1873, was 24h 37m 22.713s, very close to the modern value of 24h 37m 22.663s. The crater Proctor on Mars is named after him. Biography Richard Proctor's father died in 1850 and his mother attended to his education. He was sent to King's College London and subsequently earned a scholarship at St John's College, Cambridge. He graduated in 1860 as 23rd wrangler. Proctor then read for the bar, but turned to astronomy and authorship instead, and in 186 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Times
''The Times'' is a British daily national newspaper based in London. It began in 1785 under the title ''The Daily Universal Register'', adopting its current name on 1 January 1788. ''The Times'' and its sister paper ''The Sunday Times'' (founded in 1821) are published by Times Newspapers, since 1981 a subsidiary of News UK, in turn wholly owned by News Corp. ''The Times'' and ''The Sunday Times'', which do not share editorial staff, were founded independently and have only had common ownership since 1966. In general, the political position of ''The Times'' is considered to be centre-right. ''The Times'' is the first newspaper to have borne that name, lending it to numerous other papers around the world, such as ''The Times of India'', ''The New York Times'', and more recently, digital-first publications such as TheTimesBlog.com (Since 2017). In countries where these other titles are popular, the newspaper is often referred to as , or as , although the newspaper is of nationa ...

Encyclopædia Britannica Eleventh Edition
The ''Encyclopædia Britannica'' Eleventh Edition (1910–1911) is a 29-volume reference work, an edition of the ''Encyclopædia Britannica''. It was developed during the encyclopaedia's transition from a British to an American publication. Some of its articles were written by the best-known scholars of the time. This edition of the encyclopaedia, containing 40,000 entries, has entered the public domain and is easily available on the Internet. Its use in modern scholarship and as a reliable source has been deemed problematic due to the outdated nature of some of its content. Modern scholars have deemed some articles as cultural artifacts of the 19th and early 20th centuries. Background The 1911 eleventh edition was assembled with the management of American publisher Horace Everett Hooper. Hugh Chisholm, who had edited the previous edition, was appointed editor in chief, with Walter Alison Phillips as his principal assistant editor. Originally, Hooper bought the rights to th ...

Monkstown, County Dublin
Monkstown (), historically known as ''Carrickbrennan'' ( gle, Carraig Bhraonáin), is a suburb in south Dublin, located in Dún Laoghaire–Rathdown, Ireland. It is on the coast, between Blackrock and Dún Laoghaire. The lands of the Carrickbrennan estate form the greater part of the civil parish of Monkstown. History A church was built at Carrickbrennan (as Monkstown was then known) before the 8th century, and dedicated to Saint Mochonna, bishop of Inispatrick or Holmpatrick by Skerries. The grange of Carrickbrennan, otherwise Monkstown, was granted by the King to the Cistercian monks of Saint Mary's Abbey, Dublin, in 1200. The monks built their grange near to the church, and the village grew up around it. The lands of which it was a part extended as far south as Bulloch harbour on the outskirts of Dalkey, where the monks constructed a fishing harbour protected by a castle. In 1539, King Henry VIII awarded the Monkstown lands to Sir John Travers, Master of the Ordnance in I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Howard Grubb
Sir Howard Grubb (28 July 1844 – 16 September 1931) was an optical designer from Dublin, Ireland. He was head of a family firm that made large optical telescopes, telescope drive controls, and other optical instruments. He is also noted for his work to perfect the periscope and inventing the reflector sight. Biography Howard Grubb was one of eight children of Thomas, founder of the Grubb Telescope Company so Howard developed an early interest in optics. He began his studies in Trinity College Dublin in 1863, but did not complete his degree. After training to be a civil engineer, Howard joined his father's firm in 1864 and gained the reputation of a first class producer of telescopes. In 1871 he married Mary Walker with whom he had six children. Grubb was elected Fellow of the Royal Society in 1883 and of the Royal Astronomical Society in 1870.

Scientific Instrument
A scientific instrument is a device or tool used for scientific purposes, including the study of both natural phenomena and theoretical research. History Historically, the definition of a scientific instrument has varied, based on usage, laws, and historical time period. Before the mid-nineteentcenturysuch tools were referred to as "natural philosophical" or "philosophical" apparatus and instruments, and older tools from antiquity to the Middle Ages (such as the astrolabe and pendulum clock) defy a more modern definition of "a tool developed to investigate nature qualitatively or quantitatively." Scientific instruments were made by instrument makers living near a center of learning or research, such as a university or research laboratory. Instrument makers designed, constructed, and refined instruments for purposes, but if demand was sufficient, an instrument would go into production as a commercial product. In a description of the use of the eudiometer by Jan Ingenhousz to show ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomical
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowadays, professiona ...

Spectroscope
An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. The variable measured is most often the light's intensity but could also, for instance, be the polarization state. The independent variable is usually the wavelength of the light or a unit directly proportional to the photon energy, such as reciprocal centimeters or electron volts, which has a reciprocal relationship to wavelength. A spectrometer is used in spectroscopy for producing spectral lines and measuring their wavelengths and intensities. Spectrometers may operate over a wide range of non-optical wavelengths, from gamma rays and X-rays into the far infrared. If the instrument is designed to measure the spectrum on an absolute scale rather than a relative one, then it is typically called a spectrophotometer. The majority o ...
