Slovak Academy Of Sciences
The Slovak Academy of Sciences ( sk, Slovenská akadémia vied, or SAV) is the main scientific and research institution in Slovakia fostering basic and strategic basic research. It was founded in 1942, closed after World War II, and then reestablished in 1953. Its primary mission is to acquire new knowledge of nature, society and technology, specifically targeted at ensuring scientific basis for the advancement in Slovakia. It comprises 58 scientific institutes and 13 ancillary institutions. The SAV edits 44 scientific and scholarly journals and 100–120 monographs per annum. Moreover, 41 scientific and scholarly societies, which associate scientists and scholars from various disciplines, are affiliated with SAV. History The commencement of modern science in the 16th and 17th centuries resulted in the establishment of new institutions that supplemented classical universities and created a broader forum for fostering science communication.

Taurids
The Taurids are an annual meteor shower, associated with the comet Encke. The Taurids are actually two separate showers, with a Southern and a Northern component. The Southern Taurids originated from Comet Encke, while the Northern Taurids originated from the asteroid 2004 TG10, possibly a large fragment of Encke due to its similar orbital parameters. They are named after their radiant point in the constellation Taurus, where they are seen to come from in the sky. Because of their occurrence in late October and early November, they are also called Halloween fireballs. Encke and the Taurids are believed to be remnants of a much larger comet, which has disintegrated over the past 20,000 to 30,000 years, breaking into several pieces and releasing material by normal cometary activity or perhaps occasionally by close encounters with the tidal force of Earth or other planets ( Whipple, 1940; Klačka, 1999). In total, this stream of matter is the largest in the inner Solar System ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ondřejov Observatory
The Ondřejov Observatory (; cs, Observatoř Ondřejov) is the principal observatory of the Astronomical Institute () of the Academy of Sciences of the Czech Republic. It is located near the village of Ondřejov, southeast of Prague, Czech Republic. It has a wide telescope, which is the largest in the Czech Republic. History The facility was constructed in 1898, by Czech amateur astronomer and entrepreneur Josef Jan Frič as a private observatory. On 28 October 1928, he donated the facility to the Czechoslovak state to celebrate the tenth anniversary of its independence. The observatory, located at an altitude of , away from the air and light pollution of urban Prague, was administered by Charles University until the founding of the Czechoslovak Academy of Sciences in 1953, which from then on operated it as part of its Astronomical Institute in conjunction with other Czechoslovak observatories. In 1967, a telescope measuring in width was added to the observatory, which at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Faculty Of Mathematics, Physics And Informatics
The Faculty of Mathematics, Physics and Informatics (FMPH; sk, FMFI; sk, Fakulta matematiky, fyziky a informatiky; colloquial: ''Matfyz'') is one of 13 faculties of the Comenius University in Bratislava, the capital of Slovakia. The faculty provides higher education in mathematics, physics and informatics, as well as teacher training in subjects related to these branches of study. It was established in 1980 by separating from the Faculty of Natural Sciences under the name of ''Faculty of Mathematics and Physics'' ( sk, Matematicko-fyzikálna fakulta). Its name was changed to the contemporary name in 2000. In 2015, Faculty of Mathematics, Physics and Informatics was ranked first in the group of natural sciences in the ranking of faculties in Slovakia by the Academic Ranking and Rating Agency (ARRA).

6001–6500
6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second smallest composite number, behind 4; its proper divisors are , and . Since 6 equals the sum of its proper divisors, it is a perfect number; 6 is the smallest of the perfect numbers. It is also the smallest Granville number, or \mathcal-perfect number. As a perfect number: *6 is related to the Mersenne prime 3, since . (The next perfect number is 28.) *6 is the only even perfect number that is not the sum of successive odd cubes. *6 is the root of the 6-aliquot tree, and is itself the aliquot sum of only one other number; the square number, . Six is the only number that is both the sum and the product of three consecutive positive numbers. Unrelated to 6's being a perfect number, a Golomb ruler of length 6 is a "perfect ruler" ...
