Ebenezer Cunningham
Ebenezer Cunningham (7 May 1881 in Hackney, London – 12 February 1977) was a British mathematician who is remembered for his research and exposition at the dawn of special relativity. Biography Cunningham went up to St John's College, Cambridge in 1899 and graduated Senior Wrangler in 1902, winning the Smith's Prize in 1904. In 1904, as a lecturer at the University of Liverpool, he began work on a new theorem in relativity with fellow lecturer Harry Bateman. They brought the methods of inversive geometry into electromagnetic theory with their transformations ( spherical wave transformation): :Each four-dimensional solution o Maxwell's equationscould then be inverted in a four-dimensional ''hypersphere of pseudo-radius K'' in order to produce a new solution. Central to Cunningham's paper was the demonstration that Maxwell's equations retained their form under these transformations. He worked with Karl Pearson in 1907 at University College London. Cunningham married Ada Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Borough Of Hackney
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as ''Londinium'' and retains its medieval boundaries.See also: Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly.

Downing Place United Reformed Church, Cambridge
Downing Place United Reformed Church, Cambridge is a church in Cambridge, United Kingdom, that is part of the United Reformed Church. It was formed in 2018 in a merger between St Columba's Church, Cambridge, and Emmanuel Church, Cambridge. The church occupies the former St Columba's building in Downing Place, which is close to a site occupied by Emmanuel's congregation before 1874. In the recent past prior to the merger of the two congregations, activities have included regular Sunday worship, a programme of music concerts, hosting an NHS group therapy centre and hosting a night-time drop-in centre hosted by Cambridge Street Pastors. The refurbishment has been designed to facilitate similar activities. History Emmanuel Church Originally a congregational church, Emmanuel voted to join the new United Reformed Church in 1972. Emmanuel had been known by different names over the years, first as the 'Hog Hill Independent Church' and then the 'Emmanuel Congregational Chapel' or ...

People Educated At Dame Alice Owen's School
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of p ...

Alumni Of St John's College, Cambridge
Alumni (singular: alumnus (masculine) or alumna (feminine)) are former students of a school, college, or university who have either attended or graduated in some fashion from the institution. The feminine plural alumnae is sometimes used for groups of women. The word is Latin and means "one who is being (or has been) nourished". The term is not synonymous with "graduate"; one can be an alumnus without graduating ( Burt Reynolds, alumnus but not graduate of Florida State, is an example). The term is sometimes used to refer to a former employee or member of an organization, contributor, or inmate. Etymology The Latin noun ''alumnus'' means "foster son" or "pupil". It is derived from PIE ''*h₂el-'' (grow, nourish), and it is a variant of the Latin verb ''alere'' "to nourish".Merriam-Webster: alumnus .. Separate, but from the ...

Bulletin Of The London Mathematical Society
The London Mathematical Society (LMS) is one of the United Kingdom's Learned society, learned societies for mathematics (the others being the Royal Statistical Society (RSS), the Institute of Mathematics and its Applications (IMA), the Edinburgh Mathematical Society and the Operational Research Society (ORS). History The Society was established on 16 January 1865, the first president being Augustus De Morgan. The earliest meetings were held in University College London, University College, but the Society soon moved into Burlington House, Piccadilly. The initial activities of the Society included talks and publication of a journal. The LMS was used as a model for the establishment of the American Mathematical Society in 1888. Mary Cartwright was the first woman to be President of the LMS (in 1961–62). The Society was granted a royal charter in 1965, a century after its foundation. In 1998 the Society moved from rooms in Burlington House into De Morgan House (named after ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conformal Group Of Spacetime
In mathematics, the conformal group of an inner product space is the group of transformations from the space to itself that preserve angles. More formally, it is the group of transformations that preserve the conformal geometry of the space. Several specific conformal groups are particularly important: * The conformal orthogonal group. If ''V'' is a vector space with a quadratic form ''Q'', then the conformal orthogonal group is the group of linear transformations ''T'' of ''V'' for which there exists a scalar ''λ'' such that for all ''x'' in ''V'' *:Q(Tx) = \lambda^2 Q(x) :For a definite quadratic form, the conformal orthogonal group is equal to the orthogonal group times the group of dilations. * The conformal group of the sphere is generated by the inversions in circles. This group is also known as the Möbius group. * In Euclidean space E''n'', , the conformal group is generated by inversions in hyperspheres. * In a pseudo-Euclidean space E''p'',''q'', the conformal ...
