Description
Watermark:
Baron Jurij Bartolomej Vega.
Avers:
Baron Jurij Bartolomej Vega (also Veha; Latin: Georgius Bartholomaei Vecha; German: Georg Freiherr von Vega; born Vehovec, March 23, 1754 – September 26, 1802) was a Slovene mathematician, physicist and artillery officer.
Born to a farmer's family[2] in the small village of Zagorica east of Ljubljana in Slovenia, Vega was 6 years old when his father Jernej Veha died. Vega was educated first in Moravče and later attended high school for six years (1767-1773) in Ljubljana (the Jesuit College of Ljubljana, Jezuitski kolegij v Ljubljani (sl)), studying Latin, Greek, religion, German, history, geography, science, and mathematics. At that time there were about 500 students there. He was a schoolfellow of Anton Tomaž Linhart, a Slovenian writer and historian. Vega finished high school when he was 19, in 1773. After completing his studies at the Lyceum of Ljubljana (Licej v Ljubljani) he became a navigational engineer in 1775. Tentamen philosophicum, a list of questions for his comprehensive examination, was preserved and is available in the Mathematical Library in Ljubljana. The problems cover logic, algebra, metaphysics, geometry, trigonometry, geodesy, stereometry, geometry of curves, ballistics, and general and special physics.
Vega left Ljubljana five years after graduation and entered military service in 1780 as a professor of mathematics at the Artillery School in Vienna. At that time he started to sign his last name as Vega and no longer Veha. When Vega was 33 he married Josefa Svoboda (Jožefa Swoboda) (1771-1800), a Czech noble from České Budějovice who was 16 at that time.
Vega participated in several wars. In 1788 he served under Austrian Imperial Field-Marshal Ernst Gideon von Laudon (1717-1790) in a campaign against the Turks at Belgrade. His command of several mortar batteries contributed considerably to the fall of the Belgrade fortress. Between 1793 and 1797 he fought French Revolutionaries under the command of Austrian General Dagobert-Sigismond de Wurmser (1724-1797) with the European coalition on the Austrian side. He fought at Fort Louis, Mannheim, Mainz, Wiesbaden, Kehl, and Dietz. In 1795 he had two 30-pound (14 kilogram) mortars cast, with conically drilled bases and a greater charge, for a firing range up to 3000 meters (3300 yards). The old 60 lb. (27 kg.) mortars had a range of only 1800 m. (2000 yd.).
In September 1802 Vega was reported missing. After a few days' search his body was found. The police report concluded that it was an accident. It is believed that he died on 26 September 1802 in Nußdorf on the Danube, near the Austrian capital, Vienna.

Revers:
Centered is the Planetary system with (right to left): Mercury, Venus, Earth with the Moon, Mars, Jupiter with twelve moons, Saturn with ten moons and Uranus, followed by Neptune and Pluto (not visible on this detail).
On top are the Lunar phases.
The lunar phase or phase of the moon is the shape of the illuminated (sunlit) portion of the Moon as seen by an observer on Earth. The lunar phases change cyclically as the Moon orbits the Earth, according to the changing positions of the Moon and Sun relative to the Earth. The Moon's rotation is tidally locked by the Earth's gravity, therefore the same lunar surface always faces Earth. This face is variously sunlit depending on the position of the Moon in its orbit. Therefore, the portion of this hemisphere that is visible to an observer on Earth can vary from about 100% (full moon) to 0% (new moon). The lunar terminator is the boundary between the illuminated and darkened hemispheres. Each of the four "intermediate" lunar phases (see below) is roughly seven days (~7.4 days) but this varies slightly due to the elliptical shape of the Moon's orbit. Aside from some craters near the lunar poles such as Shoemaker, all parts of the Moon see around 14.77 days of sunlight, followed by 14.77 days of "night". (The side of the Moon facing away from the Earth is sometimes called the "dark side of the Moon", although that is a misnomer.)
In top left corner is the building of Slovenian Academy of Sciences and Arts (middle of XVIII century, architect - J. Shemrl) (Slovenska akademija znanosti in umetnosti).
It is the national academy of Slovenia, which encompasses science and the arts and brings together the top Slovene researchers and artists as members of the academy.
SAZU was established in 1938 and was initially named Academy of Sciences and Arts (AZU). On 23 January 1943, AZU breached the cultural silence. Due to the efforts of Milan Vidmar, the epithet Slovenian was added to its name in 1943 with a decree by Leon Rupnik, the mayor of Ljubljana under the Italian annexation. The renaming was disregarded after the war.
In autumn 1945, the National Government of Slovenia led by Boris Kidrič took autonomy from the Academy and again named it Academy of Sciences and Arts. The literary historian France Kidrič was elected its president, and confirmed for the second term in 1948. In 1948, it lost even more autonomy and was renamed to the Slovenian Academy of Sciences and Arts again. The academy lost its members with the new act and 30 days later ceased to exist. In 1949, an amendment to the act was passed that allowed for membership not only of scientists and artists, but also of those the deeds of which had a "special significance". In this manner, Josip Broz - Tito and Edvard Kardelj became its honorary members. Boris Kidrič, Josip Vidmar and Boris Ziherl were elected members, which significantly influenced the development of the Academy.
According to the Soviet scheme of development, the Institute of Physics and the Institute of Chemistry were established in 1946, followed by the Institute of Electrical Economics four years later. Despite this, humanistics, social sciences and classical natural history remained the dominating fields. In 1950, there were ten institutes, one board and one committee, among them the Institute of Slovene language and the Institute of Literatures. In this time, the Academy divided into five classes: a class for historical and social sciences, a class for philological and literary sciences, a class for mathematical-physical and technical sciences, a class for natural history and medicine, and a class for arts. This make its composition similar to the current one.
SAZU joined the European Scientific Foundation in 1995.
