picture info	Finns Finns or Finnish people ( fi, suomalaiset, ) are a Baltic Finnic ethnic group native to Finland. Finns are traditionally divided into smaller regional groups that span several countries adjacent to Finland, both those who are native to these countries as well as those who have resettled. Some of these may be classified as separate ethnic groups, rather than subgroups of Finns. These include the Kvens and Forest Finns in Norway, the Tornedalians in Sweden, and the Ingrian Finns in Russia. Finnish, the language spoken by Finns, is closely related to other Balto-Finnic languages, e.g. Estonian and Karelian. The Finnic languages are a subgroup of the larger Uralic family of languages, which also includes Hungarian. These languages are markedly different from most other languages spoken in Europe, which belong to the Indo-European family of languages. Native Finns can also be divided according to dialect into subgroups sometimes called ''heimo'' (lit. ''tribe''), although suc ...

picture info	Åbo Akademi University Åbo Akademi University ( sv, Åbo Akademi , ) is the only exclusively Swedish language multi-faculty university in Finland (or anywhere outside Sweden). It is located mainly in Turku (Åbo is the Swedish name of the city) but has also activities in Vaasa. Åbo Akademi should not be confused with the Royal Academy of Åbo, which was founded in 1640, but moved to Helsinki after the Turku fire of 1827 and is today known as the University of Helsinki. Åbo Akademi was founded by private donations in 1918 as the third university in Finland, both to let Turku again become a university town and because it was felt that the Swedish language was threatened at the University of Helsinki. The Finnish University of Turku was founded in 1920, also by private donations and for similar reasons. Åbo Akademi was a private institution until 1981, when it was turned into a public institution. As the only uni-lingually Swedish multi-faculty university in the world outside Sweden and consequent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Academic Staff Of Åbo Akademi University 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.

picture info	Year Of Birth Missing (living People) A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
