Dunsink
Dunsink () is a townland in the civil parish of Castleknock, Dublin, in Ireland. The townland has an area of approximately , and had a population of 323 people as of the 2011 census. The townland is the site of Dunsink Observatory, where William Rowan Hamilton and Hermann Brück were directors. Built in 1783–1785, it is the oldest scientific institution in Ireland. The observatory houses a 12-inch (30 cm) refracting telescope which was built by Grubbs of Dublin using a French manufactured lens. It is situated on a hill 8 km northwest of Dublin's city centre, where the astronomy section of the School of Cosmic Physics in the Dublin Institute for Advanced Studies is located. The ''1880 Definition of Time Act'' set the official time in Ireland to be Dublin Mean Time. This was computed as the time at Dunsink, which was about GMT-25m21. In 1916, another act moved Ireland to Greenwich Mean Time. Dunsink time is mentioned five times in James Joyce James Augustine A ...

Dunsink Observatory
The Dunsink Observatory is an astronomical observatory established in 1785 in the townland of Dunsink in the outskirts of the city of Dublin, Ireland.Alexander Thom''Irish Almanac and Official Directory''7th ed., 1850 p. 258. Retrieved: 2011-02-22. Dunsink's most famous director was William Rowan Hamilton, who, amongst other things, discovered quaternions, the first non-commutative algebra form, while walking from the observatory to the city with his wife. The annual Hamilton Walk that commemorates this discovery begins at the observatory. He is also renowned for his Hamiltonian formulation of dynamics. History The observatory was established by an endowment of £3,000 in the will of Francis Andrews, who was Provost of Trinity College Dublin at his death on 18 June 1774. The site was established on the south slope of a low hill in the townland of Dunsink, 84m above sea level. The South Telescope, a 12-inch Grubb instrument, is a refracting (i.e. it uses lens) telescope built ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Rowan Hamilton
Sir William Rowan Hamilton LL.D, DCL, MRIA, FRAS (3/4 August 1805 – 2 September 1865) was an Irish mathematician, astronomer, and physicist. He was the Andrews Professor of Astronomy at Trinity College Dublin, and Royal Astronomer of Ireland, living at Dunsink Observatory. Hamilton's scientific career included the study of geometrical optics, ideas from Fourier analysis, and his work on quaternions which made him one of the founders of modern linear algebra. He made major contributions in optics, classical mechanics and abstract algebra. His work was fundamental to modern theoretical physics, particularly his reformulation of Newtonian mechanics, now called Hamiltonian mechanics. It is now central both to electromagnetism and to quantum mechanics. Early life Hamilton was the fourth of nine children born to Sarah Hutton (1780–1817) and Archibald Hamilton (1778–1819),Bruno (2003) who lived in Dublin at 29 Dominick Street, later renumbered to 36.

Dublin Institute For Advanced Studies
The Dublin Institute for Advanced Studies (DIAS) ( ga, Institiúid Ard-Léinn Bhaile Átha Cliath) is a statutory independent research institute in Ireland. It was established in 1940 on the initiative of the Taoiseach, Éamon de Valera, in Dublin. The institute consists of three schools: the School of Theoretical Physics, the School of Cosmic Physics and the School of Celtic Studies. The directors of these schools are, as of 2022, Professor Denjoe O'Connor, Professor Chris Bean and Professor Ruairí Ó hUiginn. The institute, under its governing act, is empowered to "train students in methods of advanced research" but does not itself award degrees; graduate students working under the supervision of Institute researchers can, with the agreement of the governing board of the appropriate school, be registered for a higher degree in any university worldwide. Following a comprehensive review of the higher education sector and its institutions, conducted by the Higher Education Auth ...

Dublin Mean Time
Ireland uses Irish Standard Time (IST, UTC+01:00; ga, Am Caighdeánach Éireannach) in the summer months and Greenwich Mean Time ( UTC+00:00; ''Meán-Am Greenwich'') in the winter period. (Roughly half of the state is in the 7.5°W to 22.5°W sector, half is in the same sector as Greenwich: 7.5°E to 7.5°W). In Ireland, the Standard Time Act 1968 legally established that ''the time for general purposes in the State (to be known as standard time) shall be one hour in advance of Greenwich mean time throughout the year''. This act was amended by the Standard Time (Amendment) Act 1971, which legally established Greenwich Mean Time as a winter time period. Ireland therefore operates one hour behind standard time during the winter period, and reverts to standard time in the summer months. This is defined in contrast to the other states in the European Union, which operate one hour ahead of standard time during the summer period, but produces the same end result. The instant of t ...

Hermann Brück
Hermann Alexander Brück CBE FRSE (15 August 1905 – 4 March 2000) was a German-born astronomer, who spent the great portion of his career in various positions in Britain and Ireland. Education Hermann Brück was born in Berlin. His father was Hermann Heinrich Brück and his mother, Margaret. Young Hermann was educated at the Kaiserin Augusta Gymnasium in Berlin-Charlottenburg, a school specialising in the Classics (Latin and Greek), where he also had excellent teachers in mathematics and physics. From 1924-28, Brück, was educated at the University of Kiel, the University of Bonn, and the Ludwig Maximilian University of Munich. His doctoral work on the wave mechanics of crystals was under the supervision of Arnold Sommerfeld. His interest in astronomy came early in life, and he turned his attention to astronomical spectroscopy. He was granted his PhD at Munich in 1928.

Castleknock
Castleknock () is an affluent suburb located west of the centre of Dublin city, Ireland. It is centered on the village of the same name in Fingal. In addition to the suburb, the name "Castleknock" also refers to older units of land division: a townland, a civil parish and a barony. Etymology In a poem relating to the earliest centuries after Christ, the origin of the name Cnucha is connected with Conn of the Hundred Battles, and the name is said to have been borne by his foster-mother: — As the word ''Castle'' did not come into use in Ireland until Norman times we know that ''Castleknock'' is a name of comparatively recent origin. Documents from the 12th and 13th centuries refer to the place as Castrum Cnoc, simply Cnoc and also Chastel-cnoc or Castel-Cnoc. So it seems that the name Castleknock is rooted in the topography of the hill or ''cnoc'' located at the centre of the modern neighbourhood and/or the personal name of the mother of a semi-legendary High King i.e. ''C ...

Irish Traveller
Irish Travellers ( ga, an lucht siúil, meaning "the walking people"), also known as Pavees or Mincéirs (Shelta: Mincéirí), are a traditionally peripatetic indigenous ethno-cultural group in Ireland.''Questioning Gypsy identity: ethnic narratives in Britain and America'' by Brian Belton They are predominantly English-speaking, though many also speak Shelta, a language of mixed English and Irish origin. The majority of Irish Travellers are Roman Catholic, the predominant religion in the Republic of Ireland. They are one of several groups identified as " Travellers", a closely related group being the Scottish Travellers. They are often incorrectly referred to as " Gypsies", but Irish Travellers are not genetically related to the Romani, who are of Indo-Aryan origin. Genetic analysis has shown Travellers to be of Irish extraction, and that they likely diverged from the settled Irish population in the 1600s, likely during the time of the Cromwellian conquest of Ireland. ...

Shakespeare And Company (1919–1941)
Shakespeare and Company was an influential English-language bookstore in Paris founded by Sylvia Beach in 1919; Beach published James Joyce's 1922 novel '' Ulysses'' at the bookstore. The store closed in 1941. Shakespeare and Company was established by Beach, an American expatriate, in November 1919, at 8 rue Dupuytren, before moving to larger premises at 12 rue de l'Odéon in the 6th arrondissement in 1921. During the 1920s, Beach's shop and lending library was a gathering place for many then-aspiring and renowned writers and poets such as Ezra Pound, Ernest Hemingway, Djuna Barnes, James Joyce, F. Scott Fitzgerald, Gertrude Stein, and Ford Madox Ford. Shakespeare and Company was forced to close in 1941 during the German occupation of Paris. Beach was arrested and imprisoned for six months by Nazi authorities. Upon her release toward the end of the war, Beach was in ill health, and was never able to reopen the store. __TOC__ History Sylvia Beach, an American expatriate ...

Ulysses (novel)
''Ulysses'' is a modernist novel by Irish writer James Joyce. Parts of it were first serialized in the American journal '' The Little Review'' from March 1918 to December 1920, and the entire work was published in Paris by Sylvia Beach on 2 February 1922, Joyce's 40th birthday. It is considered one of the most important works of modernist literature and has been called "a demonstration and summation of the entire movement." According to Declan Kiberd, "Before Joyce, no writer of fiction had so foregrounded the process of thinking". ''Ulysses'' chronicles the appointments and encounters of the itinerant Leopold Bloom in Dublin in the course of an ordinary day, 16 June 1904. Ulysses is the Latinised name of Odysseus, the hero of Homer's epic poem the ''Odyssey'', and the novel establishes a series of parallels between the poem and the novel, with structural correspondences between the characters and experiences of Bloom and Odysseus, Molly Bloom and Penelope, and Stephen Ded ...

James Joyce
James Augustine Aloysius Joyce (2 February 1882 – 13 January 1941) was an Irish novelist, poet, and literary critic. He contributed to the modernist avant-garde movement and is regarded as one of the most influential and important writers of the 20th century. Joyce's novel '' Ulysses'' (1922) is a landmark in which the episodes of Homer's ''Odyssey'' are paralleled in a variety of literary styles, particularly stream of consciousness. Other well-known works are the short-story collection '' Dubliners'' (1914), and the novels '' A Portrait of the Artist as a Young Man'' (1916) and '' Finnegans Wake'' (1939). His other writings include three books of poetry, a play, letters, and occasional journalism. Joyce was born in Dublin into a middle-class family. He attended the Jesuit Clongowes Wood College in County Kildare, then, briefly, the Christian Brothers-run O'Connell School. Despite the chaotic family life imposed by his father's unpredictable finances, he excelled at the Jes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
