Science
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...

Justus Von Liebig
Justus Freiherr von Liebig (12 May 1803 – 20 April 1873) was a German scientist who made major contributions to agricultural and biological chemistry, and is considered one of the principal founders of organic chemistry. As a professor at the University of Giessen, he devised the modern laboratory-oriented teaching method, and for such innovations, he is regarded as one of the greatest chemistry teachers of all time. He has been described as the "father of the fertilizer industry" for his emphasis on nitrogen and trace minerals as essential plant nutrients, and his formulation of the law of the minimum, which described how plant growth relied on the scarcest nutrient resource, rather than the total amount of resources available. He also developed a manufacturing process for beef extracts, and with his consent a company, called Liebig Extract of Meat Company, was founded to exploit the concept; it later introduced the Oxo brand beef bouillon cube. He popularized an earlier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Witham
Henry Thomas Maire Witham FRSE FGS (1779–1844) was a British landowner remembered as an amateur palaeontologist and mineralogist. He was an early researcher into the internal structure of fossil plants. Life He was born Henry Silvertop the son of John Silvertop of Minsteracres in Northumberland. His mother was Catherine Lawson of Brough. He was a compulsive gambler and ran up debts of £105,000 (a truly huge sum in the 1820s) and was forced to sell off much of his property to settle his debts. From 1826 to 1832 he lived in Edinburgh at 14 Great King Street. During his time in Edinburgh (in 1827) he was elected a Fellow of the Royal Society of Edinburgh, his proposer being Thomas Allan. Though having no botanical training, he applied William Nicol's method of examining fossils and rocks under the microscope by slicing them into thin sections. Nicol's first published account of this process is contained in Witham's 1831 publication, ''Observations of Fossil Vegetables'' ...

Public Health
Public health is "the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals". Analyzing the determinants of health of a population and the threats it faces is the basis for public health. The ''public'' can be as small as a handful of people or as large as a village or an entire city; in the case of a pandemic it may encompass several continents. The concept of ''health'' takes into account physical, psychological, and social well-being.What is the WHO definition of health? from the Preamble to the Constitution of WHO as adopted by the International Health Conference, New York, 19 June - 22 July 1946; signed on ...

Occupational Health
Occupational safety and health (OSH), also commonly referred to as occupational health and safety (OHS), occupational health, or occupational safety, is a multidisciplinary field concerned with the safety, health, and welfare of people at work (i.e. in an occupation). These terms also refer to the goals of this field, so their use in the sense of this article was originally an abbreviation of ''occupational safety and health program/department'' etc. The goal of an occupational safety and health program is to foster a safe and healthy occupational environment. OSH also protects all the general public who may be affected by the occupational environment.Fanning, Fred E. (2003). Basic Safety Administration: A Handbook for the New Safety Specialist, Chicago: American Society of Safety Engineers Globally, more than 2.78 million people die annually as a result of workplace-related accidents or diseases, corresponding to one death every fifteen seconds.

Charles Thackrah
Charles Turner Thackrah, MRCS Eng; (1795, in Leeds – 1833) was an English surgeon. He was a pioneer in the field of occupational medicine and is known for his work ''The Effects of the Principal Arts, Trades, and Professions, and of Civic States and Habits of Living, on Health and Longevity''. He was a founder member of the Leeds School of Medicine. He died of tuberculosis in 1833, at the age of 38. A building was opened in his honor and given his name at the University of Leeds in around 2007. He is not to be confused with Charles Thackray who gave his name to the Thackray Museum of Medicine The Thackray Museum of Medicine in Leeds, West Yorkshire, England, is a museum of the history of medicine adjacent to St James's University Hospital.

William Charles Ellis
Sir William Charles Ellis (10 March 1780 – 24 October 1839) was the superintendent of the West Riding Pauper Lunatic Asylum. His ideas on the treatment of mental illness became widely influential. Biography Ellis was born in Alford, Lincolnshire. His early career was as an apothecary in Hull, but he soon took an interest in the treatment of mental disorders.Smith, Leonard D. (2004) "Ellis, Sir William Charles (1780–1839)" in ''Oxford Dictionary of National Biography''. Oxford University Press This he learnt at the Sculcoates Refuge in Hull; which was run on a similar model as the York Retreat. In 1817 a William Ellis was appointed as superintendent to the newly built West Riding Pauper Lunatic Asylum at Wakefield. A Methodist, Ellis too had strong religious convictions. With his wife as matron, he employed the same principles of humane treatment and moral therapy as practised at Sculcoates Refuge. After 13 years their reputation had become such that they were invited to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hanwell
Hanwell () is a town in the London Borough of Ealing, in the historic County of Middlesex, England. It is about 1.5 miles west of Ealing Broadway and had a population of 28,768 as of 2011. It is the westernmost location of the London post town. Hanwell is mentioned in the Domesday Book. St Mary's Church was established in the tenth century and has been rebuilt three times since, the present church dating to 1842. Schools were established around this time in Hanwell; notably Central London District School which Charlie Chaplin attended.

St Bernard's Hospital, Hanwell
St Bernard's Hospital, also known as Hanwell Insane Asylum and the Hanwell Pauper and Lunatic Asylum, was an asylum built for the pauper insane, opening as the First Middlesex County Asylum in 1831. Some of the original buildings are now part of the headquarters for the West London Mental Health NHS Trust (WLMHT). Its first superintendent, Dr William Charles Ellis, was known in his lifetime for his pioneering work and his adherence to his "great principle of therapeutic employment". Sceptical contemporaries were amazed that such therapy speeded recovery at Hanwell. This greatly pleased the visiting Justices of the Peace as it reduced the long term cost of keeping each patient. Under the third superintendent John Conolly the institution became famous as the first large asylum to dispense with all mechanical restraints. The asylum is next to the village of Hanwell but parochially was in Southall (officially in the 1830s the northern precinct (chapelry) of Norwood). It is about 8 ...

Plymouth
Plymouth () is a port city and unitary authority in South West England. It is located on the south coast of Devon, approximately south-west of Exeter and south-west of London. It is bordered by Cornwall to the west and south-west. Plymouth's early history extends to the Bronze Age when a first settlement emerged at Mount Batten. This settlement continued as a trading post for the Roman Empire, until it was surpassed by the more prosperous village of Sutton founded in the ninth century, now called Plymouth. In 1588, an English fleet based in Plymouth intercepted and defeated the Spanish Armada. In 1620, the Pilgrim Fathers departed Plymouth for the New World and established Plymouth Colony, the second English settlement in what is now the United States of America. During the English Civil War, the town was held by the Roundhead, Parliamentarians and was besieged between 1642 and 1646. Throughout the Industrial Revolution, Plymouth grew as a commercial shipping port, handling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boothia Peninsula
Boothia Peninsula (; formerly ''Boothia Felix'', Inuktitut ''Kingngailap Nunanga'') is a large peninsula in Nunavut's northern Canadian Arctic, south of Somerset Island. The northern part, Murchison Promontory, is the northernmost point of mainland Canada. Geography Bellot Strait (Ikirahaq) separates the peninsula from Somerset Island to the north. Babbage Bay is on the east coast, as is Abernethy Bay, just to the south. The community of Taloyoak lies in the far south and is the peninsula's only significant population centre. Paisley Bay is on the west coast, as is Wrottesley Inlet (between Paisley Bay and Bellot Strait). Prior to the detachment of Nunavut in 1999, the Boothia Peninsula and the nearby Melville Peninsula were the only parts of mainland Canada that belonged to the District of Franklin in the then Northwest Territories. The balance of the District of Franklin was all situated within the Arctic Archipelago. Exploration John Ross was forced by ice to s ...
