Thomas Oldham
Thomas Oldham (4 May 1816, Dublin – 17 July 1878, Rugby) was an Anglo-Irish geologist. He was educated at Trinity College, Dublin and studied civil engineering at the University of Edinburgh as well as geology under Robert Jameson. In 1838 he joined the ordnance survey in Ireland as a chief assistant under Joseph Ellison Portlock who was studying the geology of Londonderry and neighbourhood. Portlock wrote of him He discovered radiating fans shaped impressions in the town of Bray in 1840. He showed this to the English palaeontologist Edward Forbes, who named it ''Oldhamia'' after him. Forbes declared them to be bryozoans, however later workers ascribed it to other plants and animals. For a while these were considered the oldest fossils in the world. He became Curator to the Geological Society of Dublin, and in 1845 succeeded John Phillips, nephew of William Smith, in the Chair of Geology at Trinity College, Dublin. He was elected a Fellow of the Royal Society in June 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dublin
Dublin (; , or ) is the capital and largest city of Republic of Ireland, Ireland. On a bay at the mouth of the River Liffey, it is in the Provinces of Ireland, province of Leinster, bordered on the south by the Dublin Mountains, a part of the Wicklow Mountains range. At the 2016 census of Ireland, 2016 census it had a population of 1,173,179, while the preliminary results of the 2022 census of Ireland, 2022 census recorded that County Dublin as a whole had a population of 1,450,701, and that the population of the Greater Dublin Area was over 2 million, or roughly 40% of the Republic of Ireland's total population. A settlement was established in the area by the Gaels during or before the 7th century, followed by the Vikings. As the Kings of Dublin, Kingdom of Dublin grew, it became Ireland's principal settlement by the 12th century Anglo-Norman invasion of Ireland. The city expanded rapidly from the 17th century and was briefly the second largest in the British Empire and sixt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fossils
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...

King's College, Cambridge
King's College is a constituent college of the University of Cambridge. Formally The King's College of Our Lady and Saint Nicholas in Cambridge, the college lies beside the River Cam and faces out onto King's Parade in the centre of the city. King's was founded in 1441 by King Henry VI soon after he had founded its sister institution at Eton College. Initially, King's accepted only students from Eton College. However, the king's plans for King's College were disrupted by the Wars of the Roses and the resultant scarcity of funds, and then his eventual deposition. Little progress was made on the project until 1508, when King Henry VII began to take an interest in the college, probably as a political move to legitimise his new position. The building of the college's chapel, begun in 1446, was finished in 1544 during the reign of Henry VIII. King's College Chapel is regarded as one of the finest examples of late English Gothic architecture. It has the world's largest fan vaul ...

Reader (academic Rank)
The title of reader in the United Kingdom and some universities in the Commonwealth of Nations, for example India, Australia and New Zealand, denotes an appointment for a senior academic with a distinguished international reputation in research or scholarship. In the traditional hierarchy of British and other Commonwealth universities, reader (and principal lecturer in the new universities) are academic ranks above senior lecturer and below professor, recognising a distinguished record of original research. Reader is similar to a professor without a chair, similar to the distinction between ''professor extraordinarius'' and ''professor ordinarius'' at some European universities, professor and chaired professor in Hong Kong and "professor name" (or associate professor) and chaired professor in Ireland. Readers and professors in the UK would correspond to full professors in the United States.Graham WebbMaking the most of appraisal: career and professional development planning for le ...

Henry Yule Oldham
Henry Yule Oldham, (14 December 1862 – 14 March 1951) was a teacher and geographer who, in 1901, conducted the definitive version of the Bedford Level experiment, a proof that the Earth is a sphere. Early life Oldham was born in Düsseldorf, Germany, the younger son of Thomas Oldham, the director of the Geological Survey of India. He was educated at Rugby and Jesus College, Oxford, matriculating at Jesus College as a commoner in 1882. Whilst at Oxford, he rowed in the college boat and was president of the Debating Society. He graduated in 1886 with a second class honours degree in Animal Morphology. Career On graduating from Oxford, Oldham took a post as a private tutor in France. This he followed with post-graduate studies at Paris University (1886-7), before becoming in turn an assistant master at Hulme Grammar School and then at Harrow School. After further post-graduate studies at Berlin University (1891–92) he became a lecturer in Geography at Owens College, Manchester ...

1897 Assam Earthquake
The Assam earthquake of 1897 occurred on 12 June 1897, in Assam, British India at 11:06 UTC, and had an estimated moment magnitude of 8.2–8.3. It resulted in approximate 1,542 human casualties and caused catastrophic damage to infrastructures. Damage from the earthquake extended into Calcutta, where dozens of buildings were severely damaged, with some buildings partially collapsing. Trembles were felt across India, reaching as far as Ahmedabad and Peshawar. Seiches were also observed in Burma. Earthquake The earthquake occurred on the south–southwest-dipping reverse Oldham Fault that forms the northern edge of the Shillong Plateau. There was a minimum displacement on the main fault of 11 m, although some calculations have placed this figure at as high as 16 m; one of the greatest for any measured earthquake. The calculated area of slip extended 180 km along the strike and from 9–45 km beneath the surface, indicating that the entire thickness of the c ...

Seismic Wave
A seismic wave is a wave of acoustic energy that travels through the Earth. It can result from an earthquake, volcanic eruption, magma movement, a large landslide, and a large man-made explosion that produces low-frequency acoustic energy. Seismic waves are studied by seismologists, who record the waves using seismometers, hydrophones (in water), or accelerometers. Seismic waves are distinguished from seismic noise (ambient vibration), which is persistent low-amplitude vibration arising from a variety of natural and anthropogenic sources. The propagation velocity of a seismic wave depends on density and elasticity of the medium as well as the type of wave. Velocity tends to increase with depth through Earth's crust and mantle, but drops sharply going from the mantle to Earth's outer core. Earthquakes create distinct types of waves with different velocities. When recorded by a seismic observatory, their different travel times help scientists locate the quake's hypocen ...

Richard Dixon Oldham
Richard Dixon Oldham FRS (; 31 July 1858 – 15 July 1936) was a British geologist who made the first clear identification of the separate arrivals of P-waves, S-waves and surface waves on seismograms and the first clear evidence that the Earth has a central core. Life Born on 31 July 1858 to Thomas Oldham, a Fellow of the Royal Society and geologist, Oldham was educated at Rugby School and the Royal School of Mines. In 1879 Oldham became an assistant-superintendent with the Geological Survey of India, working in the Himalayas. He wrote about 40 publications for the Survey on geological subjects including hot springs, the geology of the Son Valley and the structure of the Himalayas and the Ganges plain. His most famous work was in seismology. His report on the 1897 Assam earthquake went far beyond reports of previous earthquakes. It included a description of the Chedrang fault, with uplift up to 35 feet and reported accelerations of the ground that had exceeded the Ear ...

Henry Benedict Medlicott
Henry Benedict Medlicott, FRS (3 August 1829 – 6 April 1905) was an Irish geologist who worked in India. He was a coauthor of a text on the geology of India and is credited with the coining of the term "Gondwana" which was later used to create the concept of Gondwanaland. Early life He was born in Loughrea, County Galway, Ireland, the son of the Church of Ireland Rector of Loughrea, Samuel Medlicott (1796–1858) and his wife Charlotte (c.1814-1884), daughter of Henry Benedict Dolphin, C. B. He was educated at Trinity College, Dublin under Thomas Oldham (1816–1875) (as well as in France, Guernsey, and Dublin. He obtained a BA in 1850 with diploma in honours in the School of Civil Engineering and an MA in 1870. He was an expert in French and was acquainted with the works of the French geologists. He joined the Geological Survey of Ireland as a general assistant in October 1851 working under Joseph Beete Jukes (1811–1869) and later with the British Geological Survey in Wil ...
