British Association For The Advancement Of Science
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 Ass ...

Charitable Organization
A charitable organization or charity is an organization whose primary objectives are philanthropy and social well-being (e.g. educational, religious or other activities serving the public interest or common good). The legal definition of a charitable organization (and of charity) varies between countries and in some instances regions of the country. The regulation, the tax treatment, and the way in which charity law affects charitable organizations also vary. Charitable organizations may not use any of their funds to profit individual persons or entities. (However, some charitable organizations have come under scrutiny for spending a disproportionate amount of their income to pay the salaries of their leadership). Financial figures (e.g. tax refund, revenue from fundraising, revenue from sale of goods and services or revenue from investment) are indicators to assess the financial sustainability of a charity, especially to charity evaluators.

Yorkshire Philosophical Society
The Yorkshire Philosophical Society (YPS) is a charitable learned society (charity reg. 529709) which aims to promote the public understanding of the natural sciences, the social sciences, and the archaeology and history of York and Yorkshire. History The Society was formed in York in December 1822 by James Atkinson, William Salmond, Anthony Thorpe and William Vernon. The Society's aim was to gain and spread knowledge related to science and history and they built a large collection for this purpose. The geologist John Phillips was employed as the Society's first keeper of its museum. In 1828 the Society was given, by royal grant, some of the grounds of St Mary's Abbey including the ruins of the abbey. On this land the Society constructed a number of buildings including the Yorkshire Museum built to house the Society's geological and archaeological collections and opened in 1830. Landscape architect Sir John Murray Naysmith was commissioned by the Society to create a botani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical Potential
The electric potential (also called the ''electric field potential'', potential drop, the electrostatic potential) is defined as the amount of work energy needed to move a unit of electric charge from a reference point to the specific point in an electric field. More precisely, it is the energy per unit charge for a test charge that is so small that the disturbance of the field under consideration is negligible. Furthermore, the motion across the field is supposed to proceed with negligible acceleration, so as to avoid the test charge acquiring kinetic energy or producing radiation. By definition, the electric potential at the reference point is zero units. Typically, the reference point is earth or a point at infinity, although any point can be used. In classical electrostatics, the electrostatic field is a vector quantity expressed as the gradient of the electrostatic potential, which is a scalar quantity denoted by or occasionally , equal to the electric potential energ ...

Volt
The volt (symbol: V) is the unit of electric potential, electric potential difference ( voltage), and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta (1745–1827). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units ( m, kg, s, and A) as : \text = \frac = \frac = \frac. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivalent to electronvolts per elementary charge: : \text = \text\Omeg ...

Electrical Resistance
The electrical resistance of an object is a measure of its opposition to the flow of electric current. Its reciprocal quantity is , measuring the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with mechanical friction. The SI unit of electrical resistance is the ohm (), while electrical conductance is measured in siemens (S) (formerly called the 'mho' and then represented by ). The resistance of an object depends in large part on the material it is made of. Objects made of electrical insulators like rubber tend to have very high resistance and low conductance, while objects made of electrical conductors like metals tend to have very low resistance and high conductance. This relationship is quantified by resistivity or conductivity. The nature of a material is not the only factor in resistance and conductance, however; it also depends on the size and shape of an object because these properties are extensive rather than i ...

Evolution Debate
Recurring cultural, political, and theology, theological rejection of evolution by religious groups (sometimes termed the creation–evolution controversy, the creation vs. evolution debate or the origins debate) exists regarding the origins of the Earth, of humanity, and of other life. In accordance with creationism, species were once widely believed to be fixed products of divine creation, but since the mid-19th century, evolution by natural selection has been established by the scientific community as an empirical Fact#In science, scientific fact. Any such debate is universally considered religious, not scientific, by professional scientific organizations worldwide: in the scientific community, evolution is accepted as fact, and efforts to sustain the traditional view are universally regarded as pseudoscience. s:Kitzmiller v. Dover Area School District/4:Whether ID Is Science#Page 83 of 139, Whether ID Is Science, p. 83.: "Virtually no secular scientists accepted the doctrin ...

1860 Oxford Evolution Debate
The 1860 Oxford evolution debate took place at the Oxford University Museum in Oxford, England, on 30 June 1860, seven months after the publication of Charles Darwin's ''On the Origin of Species''. Several prominent British scientists and philosophers participated, including Thomas Henry Huxley, Bishop Samuel Wilberforce, Benjamin Brodie, Joseph Dalton Hooker and Robert FitzRoy. The encounter is often known as the Huxley–Wilberforce debate or the Wilberforce–Huxley debate, although this description is somewhat misleading. It was not a formal debate between the two, but rather it was an animated discussion after the presentation of a paper by John William Draper of New York University, on the intellectual development of Europe with relation to Darwin's theory (one of a number of scientific papers presented during the week as part of the British Association's annual meeting).Oxford Chronicle, 7 July 1860.

Samuel Wilberforce
Samuel Wilberforce, FRS (7 September 1805 – 19 July 1873) was an English bishop in the Church of England, and the third son of William Wilberforce. Known as "Soapy Sam", Wilberforce was one of the greatest public speakers of his day. Natural History Museum. Samuel Wilberforce'. Retrieved on 14 February 2008. He is now best remembered for his opposition to Charles Darwin's theory of evolution at a debate in 1860. Early life He was born at Clapham Common, London, the fifth child of William Wilberforce, a major campaigner against the slave trade and slavery, and Barbara Spooner; he was the younger brother of Robert Isaac Wilberforce. He had an Anglican education, outside the English public schools. This was the "private and domestic" pattern of instruction chosen for his sons by William Wilberforce. It concentrated on a traditional teaching of the classics, but in a clerical home environment. Samuel Wilberforce was from 1812 under Stephen Langston, and then Edward Gar ...

Thomas Henry Huxley
Thomas Henry Huxley (4 May 1825 – 29 June 1895) was an English biologist and anthropologist specialising in comparative anatomy. He has become known as "Darwin's Bulldog" for his advocacy of Charles Darwin's theory of evolution. The stories regarding Huxley's famous 1860 Oxford evolution debate with Samuel Wilberforce were a key moment in the wider acceptance of evolution and in his own career, although some historians think that the surviving story of the debate is a later fabrication. Huxley had been planning to leave Oxford on the previous day, but, after an encounter with Robert Chambers, the author of '' Vestiges'', he changed his mind and decided to join the debate. Wilberforce was coached by Richard Owen, against whom Huxley also debated about whether humans were closely related to apes. Huxley was slow to accept some of Darwin's ideas, such as gradualism, and was undecided about natural selection, but despite this he was wholehearted in his public support of D ...

Earth's Magnetic Field
Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun. The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo. The magnitude of Earth's magnetic field at its surface ranges from . As an approximation, it is represented by a field of a magnetic dipole currently tilted at an angle of about 11° with respect to Earth's rotational axis, as if there were an enormous bar magnet placed at that angle through the center of Earth. The North geomagnetic pole actually represents the South pole of Earth's magnetic field, and conversely the South geomagnetic pole corresponds to the north pole of Earth's magneti ...

Meteorology
Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century. The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data. It was not until after the elucidation of the laws of physics, and more particularly in the latter half of the 20th century the development of the computer (allowing for the automated solution of a great many modelling equations) that significant breakthroughs in weather forecasting were achieved. An important branch of weather forecasting is marine weather forecasting as it relates to maritime and coastal safety, in which weather effects also include atmospheric interactions with large bodies of water.

Francis Ronalds
Sir Francis Ronalds FRS (21 February 17888 August 1873) was an English scientist and inventor, and arguably the first electrical engineer. He was knighted for creating the first working electric telegraph over a substantial distance. In 1816 he laid an eight-mile length of iron wire between wooden frames in his mother's garden and sent pulses using electrostatic generators. Upbringing and family Born to Francis Ronalds and Jane (née Field), wholesale cheesemongers, at their business premises in Upper Thames Street, London, he attended Unitarian minister Eliezer Cogan's school before being apprenticed to his father at the age of 14 through the Drapers' Company. He ran the large business for some years. The family later resided in Canonbury Place and Highbury Terrace, both in Islington, at Kelmscott House in Hammersmith, Queen Square in Bloomsbury, at Croydon, and on Chiswick Lane. Several of Ronalds' eleven brothers and sisters also led noteworthy lives. His youngest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
