Sir Ronald Fisher Window
A stained glass window commemorating British statistician, geneticist, and eugenicist R. A. Fisher was installed in the dining hall of Gonville and Caius College in Cambridge, England in 1989. It depicts a 7x7 Latin square, as featured in Fisher's ''The Design of Experiments''. The idea for the window came from a college fellow, A. W. F. Edwards, and the execution was the work of Maria McClafferty. At first there were two windows, the other featuring a Venn diagram to commemorate John Venn, both installed in time for the 1990 centenary of Fisher's birth. In 1992, the set was expanded with four more windows representing scientific achievements with links to the college: a DNA spiral celebrating Francis Crick, and windows celebrating Charles Scott Sherrington, George Green and James Chadwick. In June 2020, during the global George Floyd protests, the college's Gate of Honour was spray-painted in protest at the installation and at Fisher's association with eugenics, and the coll ...

George Green (mathematician)
George Green (14 July 1793 – 31 May 1841) was a British mathematical physicist who wrote '' An Essay on the Application of Mathematical Analysis to the Theories of Electricity and Magnetism'' in 1828. The essay introduced several important concepts, among them a theorem similar to the modern Green's theorem, the idea of potential functions as currently used in physics, and the concept of what are now called Green's functions. Green was the first person to create a mathematical theory of electricity and magnetism and his theory formed the foundation for the work of other scientists such as James Clerk Maxwell, William Thomson, and others. His work on potential theory ran parallel to that of Carl Friedrich Gauss. Green's life story is remarkable in that he was almost entirely self-taught. He received only about one year of formal schooling as a child, between the ages of 8 and 9. Early life Green was born and lived for most of his life in the English town of Sneinton, Nott ...

Monuments And Memorials Removed During The George Floyd Protests
During the George Floyd protests, civil unrest that followed the murder of George Floyd in May 2020, a number of monuments and memorials Decolonization of public space, associated with racial injustice were De-commemoration, vandalized, destroyed or removed, or commitments to remove them were announced. This occurred mainly in the United States, but also in several other countries. Some of the monuments in question had been the subject of lengthy, Removal of Confederate monuments and memorials, years-long efforts to remove them, sometimes involving legislation and/or court proceedings. In some cases the removal was legal and official; in others, most notably in Alabama and North Carolina, laws prohibiting the removal of monuments were deliberately broken. Initially, protesters targeted monuments related to the Confederate States of America. As the scope of the protests broadened to include other forms of systemic racism, many statues of other controversial figures such as Chr ...

Stained Glass Windows
Stained glass refers to coloured glass as a material or art and architectural works created from it. Although it is traditionally made in flat panels and used as windows, the creations of modern stained glass artists also include three-dimensional structures and sculpture. Modern vernacular usage has often extended the term "stained glass" to include domestic lead light and ''objets d'art'' created from glasswork, for example in the famous lamps of Louis Comfort Tiffany. As a material ''stained glass'' is glass that has been coloured by adding metallic salts during its manufacture. It may then be further decorated in various ways. The coloured glass may be crafted into a stained-glass window, say, in which small pieces of glass are arranged to form patterns or pictures, held together (traditionally) by strips of lead, called cames or calms, and supported by a rigid frame. Painted details and yellow-coloured silver stain are often used to enhance the design. The term ''staine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1989 Establishments In England
1989 was a turning point in political history with the "Revolutions of 1989" which ended communism in Eastern Bloc of Europe, starting in Poland and Hungary, with experiments in power-sharing coming to a head with the opening of the Berlin Wall in November, the Velvet Revolution in Czechoslovakia and the overthrow of the communist dictatorship in Romania in December; the movement ended in December 1991 with the dissolution of the Soviet Union. Revolutions against communist governments in Eastern Europe mainly succeeded, but the year also saw the suppression by the Chinese government of the 1989 Tiananmen Square protests in Beijing. It was the year of the first Brazilian direct presidential election in 29 years, since the end of the military government in 1985 that ruled the country for more than twenty years, and marked the redemocratization process's final point. F. W. de Klerk was elected as State President of South Africa, and his regime gradually dismantled the apar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Maynard Keynes
John Maynard Keynes, 1st Baron Keynes ( ; 5 June 1883 – 21 April 1946), was an English economist and philosopher whose ideas fundamentally changed the theory and practice of macroeconomics and the economic policies of governments. Originally trained in mathematics, he built on and greatly refined earlier work on the causes of business cycles. One of the most influential economists of the 20th century, he produced writings that are the basis for the schools of economic thought, school of thought known as Keynesian economics, and its various offshoots. His ideas, reformulated as New Keynesianism, are fundamental to mainstream economics, mainstream macroeconomics. He is known as the "father of macroeconomics". During the Great Depression of the 1930s, Keynes spearheaded Keynesian Revolution, a revolution in economic thinking, challenging the ideas of neoclassical economics that held that free markets would, in the short to medium term, automatically provide full employment, as ...

Eugenics
Eugenics is a set of largely discredited beliefs and practices that aim to improve the genetic quality of a human population. Historically, eugenicists have attempted to alter the frequency of various human phenotypes by inhibiting the fertility of those considered inferior, or promoting that of those considered superior. The contemporary history of eugenics began in the late 19th century, when a popular eugenics movement emerged in the United Kingdom, and then spread to many countries, including the United States, Canada, Australia, and most European countries (e.g. Sweden and Germany). In this period, people from across the political spectrum espoused eugenics. Many countries adopted eugenic policies intended to improve the quality of their populations. Historically, the idea of ''eugenics'' has been used to argue for a broad array of practices ranging from prenatal care for mothers deemed genetically desirable to the forced sterilization and murder of those deemed unf ...

James Chadwick
Sir James Chadwick (20 October 1891 – 24 July 1974) was an English nuclear physicist who received the Nobel Prize in Physics in 1935 for his discovery of the neutron. In 1941, he wrote the final draft of the MAUD Report, which inspired the U.S. government to begin serious atomic bomb research efforts. He was the head of the British team that worked on the Manhattan Project during World War II. He was knighted in Britain in 1945 for his achievements in nuclear physics. Chadwick graduated from the Victoria University of Manchester in 1911, where he studied under Ernest Rutherford (known as the "father of nuclear physics"). At Manchester, he continued to study under Rutherford until he was awarded his MSc in 1913. The same year, Chadwick was awarded an 1851 Research Fellowship from the Royal Commission for the Exhibition of 1851. He elected to study beta radiation under Hans Geiger in Berlin. Using Geiger's recently developed Geiger counter, Chadwick was able to demons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Scott Sherrington
Sir Charles Scott Sherrington (27 November 1857 – 4 March 1952) was a British neurophysiology, neurophysiologist. His experimental research established many aspects of contemporary neuroscience, including the concept of the spinal reflex as a system involving connected neurons (the "neuron doctrine"), and the ways in which signal transmission between neurons can be potentiated or depotentiated. Sherrington himself coined the word "synapse" to define the connection between two neurons. His book ''The Integrative Action of the Nervous System'' (1906) is a synthesis of this work, in recognition of which he was awarded the Nobel Prize in Physiology or Medicine in 1932 (along with Edgar Adrian). In addition to his work in physiology, Sherrington did research in histology, bacteriology, and pathology. He was president of the Royal Society in the early 1920s. Biography Early years and education Official biographies claim Charles Scott Sherrington was born in Islington, London, Engl ...
