Ruth Nanda Anshen
Ruth Nanda Anshen (June 14, 1900 – December 2, 2003) was an American philosopher, author and editor. She was the author of several books including ''The Anatomy of Evil'', ''Biography of An Idea'', ''Morals Equals Manners'' and ''The Mystery of Consciousness: A Prescription for Human Survival''. Life Anshen was born on June 14, 1900, in Lynn, Massachusetts, to Jewish Russian immigrants. She studied at Boston University under Alfred North Whitehead. During her education, she developed a desire to unite scholars from all over the world from varying fields. In 1941, she put together the Science of Culture Series, hoping to develop a "unitary principle under which there could be subsumed and evaluated the nature of man and the nature of life, the relationship of knowledge to life." Death Ruth Nanda Anshen died at age 103 in New York City on December 2, 2003. Affiliations and legacy She was a Fellow of the Royal Society of Arts of London, a member of the American Philosophica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Convergence (logic)
In mathematics, computer science and logic, convergence is the idea that different sequences of transformations come to a conclusion in a finite amount of time (the transformations are terminating), and that the conclusion reached is independent of the path taken to get to it (they are confluent). More formally, a preordered set of term rewriting transformations are said to be convergent if they are confluent and terminating. See also * Logical equality *Logical equivalence In logic and mathematics, statements p and q are said to be logically equivalent if they have the same truth value in every model. The logical equivalence of p and q is sometimes expressed as p \equiv q, p :: q, \textsfpq, or p \iff q, depending ... * Rule of replacement References Rewriting systems {{plt-stub ...

Point-set Topology
In mathematics, general topology (or point set topology) is the branch of topology that deals with the basic set-theoretic definitions and constructions used in topology. It is the foundation of most other branches of topology, including differential topology, geometric topology, and algebraic topology. The fundamental concepts in point-set topology are ''continuity'', ''compactness'', and ''connectedness'': * Continuous functions, intuitively, take nearby points to nearby points. * Compact sets are those that can be covered by finitely many sets of arbitrarily small size. * Connected sets are sets that cannot be divided into two pieces that are far apart. The terms 'nearby', 'arbitrarily small', and 'far apart' can all be made precise by using the concept of open sets. If we change the definition of 'open set', we change what continuous functions, compact sets, and connected sets are. Each choice of definition for 'open set' is called a ''topology''. A set with a topology i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Convergence Space
In mathematics, a convergence space, also called a generalized convergence, is a set together with a relation called a that satisfies certain properties relating elements of ''X'' with the Family of sets, family of Filter (set theory), filters on ''X''. Convergence spaces generalize the notions of Filters in topology, convergence that are found in point-set topology, including Metric space, metric convergence and uniform convergence. Every topological space gives rise to a canonical convergence but there are convergences, known as , that do not arise from any topological space. An example of convergence that is in general non-topological is almost everywhere convergence. Many topological properties have generalizations to convergence spaces. Besides its ability to describe notions of convergence that Topology (structure), topologies are unable to, the Category (mathematics), category of convergence spaces has an important categorical property that the category of topological spac ...

Convergence (SSL)
Convergence was a proposed strategy for replacing SSL certificate authorities, first put forth by Moxie Marlinspike in August 2011 while giving a talk titled "SSL and the Future of Authenticity" at the Black Hat security conference. It was demonstrated with a Firefox addon and a server-side notary daemon. In the talk, Marlinspike proposed that all of the current problems with the certificate authority (CA) system could be reduced to a single missing property, which he called "trust agility" and which Convergence aimed to provide. The strategy claimed to be agile, secure, and distributed. As of 2013, Marlinspike was focused on an IETF proposal called TACK, which was designed to be an uncontroversial first step that advocates for dynamic certificate pinning instead of full CA replacement and reduces the number of times a third party needs to be trusted. Development of Convergence was continued in a "Convergence Extra" fork until about 2014. Background Convergence was based o ...

Convergence (routing)
Convergence is the state of a set of routers that have the same topological information about the internetwork in which they operate. For a set of routers to have ''converged'', they must have collected all available topology information from each other via the implemented routing protocol, the information they gathered must not contradict any other router's topology information in the set, and it must reflect the real state of the network. In other words: in a converged network all routers "agree" on what the network topology looks like. Convergence is an important notion for a set of routers that engage in dynamic routing. All interior gateway protocols rely on convergence to function properly. "To have, or be, converged" is the normal state of an operational autonomous system. The Exterior Gateway Routing Protocol BGP typically never converges because the Internet is too big for changes to be communicated fast enough. Convergence process When a routing protocol proce ...

Convergent Evolution
Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is Cladogram#Homoplasies, homoplasy. The recurrent evolution of flight is a classic example, as flying pterygota, insects, birds, pterosaurs, and bats have independently evolved the useful capacity of flight. Functionally similar features that have arisen through convergent evolution are ''analogous'', whereas ''homology (biology), homologous'' structures or traits have a common origin but can have dissimilar functions. Bird, bat, and pterosaur wings are analogous structures, but their forelimbs are homologous, sharing an ancestral state despite serving different functions. The opposite of convergence is divergent evolution, where related species evolve different trai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Convergence (sustainability Science)
Convergence in sustainability sciences refers to mechanisms and pathways that lead towards sustainability with a specific focus on 'Equity within biological planetary limits'. These pathways and mechanisms explicitly advocate equity and recognise the need for redistribution of the Earth's resources in order for human society to operate enduringly within the Earth's biophysical limits. The term was first introduced by Phillip A. Sharp and Robert Langer in 2011 in the context of biomedical science. They called for a problem-solving approach that integrated knowledge from the fields of engineering, the physical sciences, computer science, and the life sciences to find solutions to human problems. The idea has since been applied in areas including climate change, environmental health, public health, Systemic bias, systemic inequities. and sustainability. One strategy is to add “friction” to undesirable practices and make them harder to do, while making the desired practices “fric ...

Convergence (eye)
A vergence is the simultaneous movement of both eyes in opposite directions to obtain or maintain single binocular vision. When a creature with binocular vision looks at an object, the eyes must rotate around a vertical axis so that the projection of the image is in the centre of the retina in both eyes. To look at an object closer, the eyes rotate towards each other ( convergence), while for an object farther away, they rotate away from each other ( divergence). Exaggerated convergence is called ''cross eyed viewing'' (focusing on the nose, for example). When looking into the distance, the eyes diverge until parallel, effectively fixating on the same point at infinity (or very far away). Vergence movements are closely connected to accommodation of the eye. Under normal visual conditions, looking at an object at a different distance will automatically cause changes in both vergence and accommodation, sometimes known as the '' accommodation-convergence reflex''. When under no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Convergence (Mexico)
Citizens' Movement (, MC) is a centre-left political party in Mexico. It was founded in 1999 under the name Convergence for Democracy, which was then shortened to Convergence in 2002 and changed to Citizens' Movement in 2011. Established on 1 August 1999, Convergence for Democracy was founded by civil society activists and former Institutional Revolutionary Party members, advocating for a social market economy and democratic reforms to increase citizen participation in governance. Once the drug war started, the party included demilitarization efforts and drug regulation in its platform. Initially aligning with left-wing coalitions since its inception, disagreements with left-wing parties prompted the party's shift to independence in elections from 2012 onwards. However, it briefly joined an alliance during the 2018 election. Since then, it has heavily focused on sustainability and social issues in its party platform. It is the third political force in the country, receiving 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
