Ramón Jardí I Borrás
Ramon Jardí i Borras (Tivissa, November 13, 1881 – June 5, 1972) was a Catalan meteorologist, astronomer and seismologist. He participated in the foundation of the Meteorological Service of Catalonia (1921–1939). He was member of the Academy of Sciences and Arts (1914), professor of electricity at Industrial School University (1917), professor at the University of Barcelona (1930–1951) and a member of the Institut d'Estudis Catalans (1926–1931). Early life Ramon Jardí studied at the Faculty of Science, where he specialized in Physical Science. After obtaining his doctorate, he taught at the University of Barcelona (1930–1951). Career In the engineering field, he modified Bourdon's anemograph that was installed at the Fabra Observatory to address design problems. He named the improved model "Bourdon-Jardí". It continues in use. Upon approval of the creation of the Meteorological Service of Catalonia by the Permanent Council of the Commonwealth of Catalonia in Se ...

Tivissa
Tivissa is a municipality in the ''comarca'' of Ribera d'Ebre, Catalonia, Spain. It is located below the La Llena massif. As well as the village of Tivissa itself, the municipality also includes the village of La Serra d'Almos, at the feet of the Montalt mountains, and the hamlets of Darmós and Llaberia. History The area was settled in prehistoric times, and cave paintings have been discovered in several sites near the village. In Iberian times, Tivissa was an important community, and the name itself may be of Iberian origin. There are the remains of an Iberian settlement at Banyoles, some five kilometres from the modern village and overlooking the Ebre river. The importance of these settlements was surely related to their position on the route through the pass of Coll de Fatxes, leading from the coast of Tarragona to what is now Zaragoza. In the Roman period, amphorae made in Tivissa made their way as far as Rome itself, presumably to transport olive oil or wine. In th ...

Engineering
Engineering is the use of scientific method, scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized List of engineering branches, fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering. The term ''engineering'' is derived from the Latin ''ingenium'', meaning "cleverness" and ''ingeniare'', meaning "to contrive, devise". Definition The American Engineers' Council for Professional Development (ECPD, the predecessor of Accreditation Board for Engineering and Technology, ABET) has defined "engineering" as: The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct o ...

Seismologists
Seismology (; from Ancient Greek σεισμός (''seismós'') meaning "earthquake" and -λογία (''-logía'') meaning "study of") is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies. It also includes studies of earthquake environmental effects such as tsunamis as well as diverse seismic sources such as volcanic, tectonic, glacial, fluvial, oceanic, atmospheric, and artificial processes such as explosions. A related field that uses geology to infer information regarding past earthquakes is paleoseismology. A recording of Earth motion as a function of time is called a seismogram. A seismologist is a scientist who does research in seismology. History Scholarly interest in earthquakes can be traced back to antiquity. Early speculations on the natural causes of earthquakes were included in the writings of Thales of Miletus (c. 585 BCE), Anaximenes of Miletus (c. 550 BCE), Aristotle (c. 340 BCE), and Zh ...

Abscissa
In common usage, the abscissa refers to the (''x'') coordinate and the ordinate refers to the (''y'') coordinate of a standard two-dimensional graph. The distance of a point from the y-axis, scaled with the x-axis, is called abscissa or x coordinate of the point. The distance of a point from x-axis scaled with the y-axis is called ordinate. For example, if (x, y) is an ordered pair in the Cartesian plane, then the first coordinate in the plane (x) is called the abscissa and the second coordinate (y) is the ordinate. In mathematics, the abscissa (; plural ''abscissae'' or ''abscissas'') and the ordinate are respectively the first and second coordinate of a point in a Cartesian coordinate system: :abscissa \equiv x-axis (horizontal) coordinate :ordinate \equiv y-axis (vertical) coordinate Usually these are the horizontal and vertical coordinates of a point in plane, the rectangular coordinate system. An ordered pair consists of two terms—the abscissa (horizontal, usually '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speed
In everyday use and in kinematics, the speed (commonly referred to as ''v'') of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity. The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is not the same as velocity. Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph). For air and marine travel, the knot is commonly used. The fastest possible speed at which energy or information can travel, according to special relativity, is the speed of light in a vacuum ''c'' = metres per second ...

Feedback
Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. The system can then be said to ''feed back'' into itself. The notion of cause-and-effect has to be handled carefully when applied to feedback systems: History Self-regulating mechanisms have existed since antiquity, and the idea of feedback had started to enter economic theory in Britain by the 18th century, but it was not at that time recognized as a universal abstraction and so did not have a name. The first ever known artificial feedback device was a float valve, for maintaining water at a constant level, invented in 270 BC in Alexandria, Egypt. This device illustrated the principle of feedback: a low water level opens the valve, the rising water then provides feedback into the system, closing the valve when the required level is reached. This then reoccurs in a circular fashion as the water level fluctuates. Centrifugal governors were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Josep Puig I Cadafalch
Josep Puig i Cadafalch (; Mataró, 17 October 1867 – Barcelona, 21 December 1956) was a Catalan '' Modernista'' architect who designed many significant buildings in Barcelona, and a politician who had a significant role in the development of Catalan institutions. He was the architect of the Casa Martí (also known as " Els Quatre Gats"), which became a place of ideas, projects and social gatherings for such well-known Catalans as Santiago Rusiñol and Ramon Casas. Although Puig's style separated him significantly from his contemporary Gaudí, their relations were neither tense nor problematic, as demonstrated by the participation of both architects in the construction of the Cafe Torino. Another of his significant buildings was the Casa Terrades (also known as "les Punxes"), which is known for its medieval castle style from the north of Europe. Puig was actively involved in politics. He was a Barcelona City Councillor from 1901 to 1903, served in the Spanish Parliament fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pluviometer
A rain gauge (also known as udometer, pluvia metior, pluviometer, ombrometer, and hyetometer) is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over a predefined area, over a period of time. It is used for determining the depth of precipitation (usually in mm) that occurs over a unit area and thus measuring rainfall amount. History The first known rainfall records were kept by the Ancient Greeks, at around 500 BCE. People living in India began to record rainfall in 400 BCE Ian Strangeways, A History of rain gauges, TerraData, 2010 The readings were correlated against expected growth. In the Arthashastra, used for example in Magadha, precise standards were set as to grain production. Each of the state storehouses were equipped with a rain gauge to classify land for taxation purposes. In 1247, the Song Chinese mathematician and inventor Qin Jiushao invented Tianchi basin rain and snow gauges to reference rain, snowfa ...

Commonwealth Of Catalonia
The Commonwealth of Catalonia ( ca, Mancomunitat de Catalunya, ) was a deliberative assembly made up of the councillors of the four provinces of Catalonia. Promoted in its final stages of gestation by the Regionalist League of Catalonia, it was strongly endorsed by municipal referendum in October 1913. The Commonwealth was created in 1914 (symbolically the 200th anniversary of the year of the loss of governing institutions independent of the Spanish central administration) and was disbanded and outlawed in 1925 during Miguel Primo de Rivera's dictatorship. Although it had only administrative functions and its powers did not go beyond those of the provincial councils, it had great symbolic and practical importance: it represented the first recognition by the Spanish State of the identity and territorial unity of Catalonia since 1714. and was responsible for the creation of many public institutions in health, culture and technical education and science and notably for the suppor ...

Outline Of Physical Science
Physical science is a branch of natural science that studies non-living systems, in contrast to life science. It in turn has many branches, each referred to as a "physical science", together called the "physical sciences". Definition Physical science can be described as all of the following: * A branch of science (a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe)."... modern science is a discovery as well as an invention. It was a discovery that nature generally acts regularly enough to be described by laws and even by mathematics; and required invention to devise the techniques, abstractions, apparatus, and organization for exhibiting the regularities and securing their law-like descriptions." —p.vii, J. L. Heilbron, (2003, editor-in-chief). ''The Oxford Companion to the History of Modern Science''. New York: Oxford University Press. . ** A branch of natural science – natural ...
