University Of Tartu
The University of Tartu (UT; et, Tartu Ülikool; la, Universitas Tartuensis) is a university in the city of Tartu in Estonia. It is the national university of Estonia. It is the only classical university in the country, and also its biggest and most prestigious university. It was founded under the name of ''Academia Gustaviana'' in 1632 by Baron Johan Skytte, the Swedish Governors-General, Governor-General (1629–1634) of Swedish Livonia, Swedish Ingria, Ingria, and Karelia (historical province of Finland), Karelia, with the required ratification provided by his long-time friend and former student – from age 7 –, King Gustavus Adolphus of Sweden, Gustavus Adolphus, shortly before the king's death on 6 November in the Battle of Lützen (1632), during the Thirty Years' War (1618–1648). Nearly 14,000 students are at the university, of whom over 1,300 are foreign students. The language of instruction in most curricula is Estonian, some more notable exceptions are taught in ...

Physical Optics
In physics, physical optics, or wave optics, is the branch of optics that studies interference, diffraction, polarization, and other phenomena for which the ray approximation of geometric optics is not valid. This usage tends not to include effects such as quantum noise in optical communication, which is studied in the sub-branch of coherence theory. Principle ''Physical optics'' is also the name of an approximation commonly used in optics, electrical engineering and applied physics. In this context, it is an intermediate method between geometric optics, which ignores wave effects, and full wave electromagnetism, which is a precise theory. The word "physical" means that it is more physical than geometric or ray optics and not that it is an exact physical theory. This approximation consists of using ray optics to estimate the field on a surface and then integrating that field over the surface to calculate the transmitted or scattered field. This resembles the Born approxima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estonian Physical Society
The Estonian Physical Society (''Eesti Füüsika Selts'', EFS) is a voluntary not-for-profit research society bringing together all those active in physics in Estonia. The EFS was established in 1989 and is affiliated with the Estonian Academy of Sciences (''Eesti Teaduste Akadeemia'') and is a European Physical Society Member Society. Presidents of the Estonian Physical Society Kaido Reivelt (University of Tartu) is the current president (since 2007). The first president of the Society was Jaak Aaviksoo, followed later by Piret Kuusk (1998-2001), Raivo Jaaniso (2001-2004), and Arvo Kikas (2004-2007).https://www.etis.ee/portaal/isikuCV.aspx?LastNameFirstLetter=K&PersonVID=329&lang=et&FromUrl0=isikud.aspx Honorary members * Henn Käämbre * Karl Rebane * Harald Keres * Jaan Einasto Jaan Einasto (born 23 February 1929) is an Estonian astrophysicist and one of the discoverers of the large-scale structure of the Universe.

GLOBE Program
The Global Learning and Observations to Benefit the Environment (GLOBE) Program is a worldwide hands-on, science and education program focusing on the environment, now active in over 120 countries worldwide. It works to promote the teaching and learning of science, enhance environmental literacy and stewardship, and promote scientific discovery. Students and teachers collect data and perform research in collaboration with scientists from numerous international agencies, and their work is made accessible through the GLOBE website. Background The GLOBE Program seeks to teach young students experimental skills using real experiments and equipment. Students, teachers, and scientists collaborate in a unique global learning network. The program is housed by the University Corporation for Atmospheric Research (UCAR) in Boulder, Colorado, and sponsored by NASA (National Aeronautics and Space Administration), NOAA (National Oceanic and Atmospheric Administration ), and the National ...

AHHAA
Science Centre AHHAA ( Estonian: ''Teaduskeskus AHHAA'') is a science centre located in Tartu, Estonia, and is currently the largest science centre in the Baltic states. AHHAA was established to promote science and technology using interactive exhibits. Since 7 May 2011, Science Centre AHHAA has been in the building located in the centre of Tartu. History AHHAA was established as a project of the University of Tartu on 1 September 1997. Since 2004 it has operated as a foundation constituted by the city of Tartu and the University of Tartu. The activities of the Science Centre AHHAA Foundation are coordinated by a committee composed of Katrin Pihor, Hannes Astok, Aune Valk, Reno Laidre and Jaanika Anderson. Additionally, the practical aspects of the activities of the foundation are appraised by a science committee composed of experts. AHHAA is governed by the board consisting of two members. Tiiu Sild was the head of the board until 2012. She was followed by Andres Juur (he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rowing (sport)
Rowing, sometimes called crew in the United States, is the sport of racing boats using oars. It differs from paddling sports in that rowing oars are attached to the boat using oarlocks, while paddles are not connected to the boat. Rowing is divided into two disciplines: sculling and sweep rowing. In sculling, each rower holds two oars—one in each hand, while in sweep rowing each rower holds one oar with both hands. There are several boat classes in which athletes may compete, ranging from single sculls, occupied by one person, to shells with eight rowers and a coxswain, called eights. There are a wide variety of course types and formats of racing, but most elite and championship level racing is conducted on calm water courses long with several lanes marked using buoys. Modern rowing as a competitive sport can be traced to the early 17th century when professional watermen held races (regattas) on the River Thames in London, England. Often prizes were offered by the London G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

21st-century Estonian Physicists
The 1st century was the century spanning AD 1 ( I) through AD 100 ( C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The 1st century also saw the appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius (AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman ...

Academic Staff Of The University Of Tartu
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
