General willIn political philosophy, the general will (volonté générale) is the will of the people as a whole. The term was made famous by 18th-century Genevan philosopher Jean-Jacques Rousseau. The phrase "general will", as Rousseau used it, occurs in Article Six of the Declaration of the Rights of Man and of the Citizen (French: Déclaration des droits de l'Homme et du citoyen), composed in 1789 during the French Revolution:The law is the expression of the general will.
Prime number theoremIn mathematics, the prime number theorem (PNT) describes the asymptotic distribution of the prime numbers among the positive integers. It formalizes the intuitive idea that primes become less common as they become larger by precisely quantifying the rate at which this occurs. The theorem was proved independently by Jacques Hadamard and Charles Jean de la Vallée Poussin in 1896 using ideas introduced by Bernhard Riemann (in particular, the Riemann zeta function).
Structuralism (architecture)Structuralism is a movement in architecture and urban planning that evolved around the middle of the 20th century. It was a reaction to Rationalism's (CIAM-Functionalism) perceived lifeless expression of urban planning that ignored the identity of the inhabitants and urban forms. Structuralism in a general sense is a mode of thought of the 20th century, which originated in linguistics. Other disciplines like anthropology, psychology, economy, philosophy and also art took on structuralist ideas and developed them further.
Jean PiagetJean William Fritz Piaget (UKpiˈæʒeɪ, USˌpiːəˈʒeɪ,_pjɑːˈʒeɪ, ʒɑ̃ pjaʒɛ; 9 August 1896 – 16 September 1980) was a Swiss psychologist known for his work on child development. Piaget's theory of cognitive development and epistemological view are together called "genetic epistemology". Piaget placed great importance on the education of children. As the Director of the International Bureau of Education, he declared in 1934 that "only education is capable of saving our societies from possible collapse, whether violent, or gradual".
Public opinionPublic opinion, or popular opinion, is the collective opinion on a specific topic or voting intention relevant to society. It is the people's views on matters affecting them. The term originates from France, and first appeared in the 17th century, though writers had identified the importance of the opinion of the people long before this. Prior to the advent of mass media, public fora such as coffee houses and gentlemen's clubs were used as exchanges of opinion and some reputable locations had great influence.
Type (biology)In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen.
Metric spaceIn mathematics, a metric space is a set together with a notion of distance between its elements, usually called points. The distance is measured by a function called a metric or distance function. Metric spaces are the most general setting for studying many of the concepts of mathematical analysis and geometry. The most familiar example of a metric space is 3-dimensional Euclidean space with its usual notion of distance. Other well-known examples are a sphere equipped with the angular distance and the hyperbolic plane.
Sardinian languageSardinian or Sard (sardu ˈsaɾdu, limba sarda ˈlimba ˈzaɾda or lìngua sarda ˈliŋɡwa ˈzaɾda) is a Romance language spoken by the Sardinians on the Western Mediterranean island of Sardinia. Many Romance linguists consider it the language that, together with Italian, is the closest to Latin among all its genealogical descendants. However, it has also incorporated elements of a Pre-Latin (mostly Paleo-Sardinian and, to a much lesser degree, Punic) substratum, as well as a Byzantine Greek, Catalan, Castilian, and Italian superstratum.
