S2 (star)
S2, also known as S0–2, is a star in the star cluster close to the supermassive black hole Sagittarius A* (Sgr A*), orbiting it with a period of 16.0518 years, a semi-major axis of about 970 au, and a pericenter distance of 17 light hours (18 Tm or 120 au) – an orbit with a period only about 30% longer than that of Jupiter around the Sun, but coming no closer than about four times the distance of Neptune from the Sun. The mass when the star first formed is estimated by the European Southern Observatory (ESO) to have been approximately . Based on its spectral type (B0V ~ B3V), it probably has a mass of 10 to 15 solar masses. Its changing apparent position has been monitored since 1995 by two groups (at UCLA and at the Max Planck Institute for Extraterrestrial Physics) as part of an effort to gather evidence for the existence of a supermassive black hole in the center of the Milky Way galaxy. The accumulating evidence points ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sacral Vertebrae
The sacrum (: sacra or sacrums), in human anatomy, is a triangular bone at the base of the spine that forms by the fusing of the sacral vertebrae (S1S5) between ages 18 and 30. The sacrum situates at the upper, back part of the pelvic cavity, between the two wings of the pelvis. It forms joints with four other bones. The two projections at the sides of the sacrum are called the alae (wings), and articulate with the ilium at the L-shaped sacroiliac joints. The upper part of the sacrum connects with the last lumbar vertebra (L5), and its lower part with the coccyx (tailbone) via the sacral and coccygeal cornua. The sacrum has three different surfaces which are shaped to accommodate surrounding pelvic structures. Overall, it is concave (curved upon itself). The base of the sacrum, the broadest and uppermost part, is tilted forward as the sacral promontory internally. The central part is curved outward toward the posterior, allowing greater room for the pelvic cavity. In all o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
S2 Expressway (Shanghai)
S, or s, is the nineteenth letter of the Latin alphabet, used in the English alphabet, the alphabets of other western European languages and other latin alphabets worldwide. Its name in English is ''ess'' (pronounced ), plural ''esses''. History Northwest Semitic šîn represented a voiceless postalveolar fricative (as in 'ip'). It originated most likely as a pictogram of a tooth () and represented the phoneme via the acrophonic principle. Ancient Greek did not have a "sh" phoneme, so the derived Greek letter Sigma () came to represent the voiceless alveolar sibilant . While the letter shape Σ continues Phoenician ''šîn'', its name ''sigma'' is taken from the letter ''Samekh'', while the shape and position of ''samekh'' but name of ''šîn'' is continued in the '' xi''. Within Greek, the name of ''sigma'' was influenced by its association with the Greek word (earlier ), "to hiss". The original name of the letter "Sigma" may have been ''san'', but due to the earl ...

Expressway S2 (Poland)
Expressway S2 is a short highway in Poland, serving as the southern section of the (partially completed) Warsaw Express Ring Road. Conceptually forming one continuous route with motorway A2, it was initially planned (since 1970s) as a part of it, however after local Warsaw residents objected to the plans of an inner-city motorway, the proposed road was downgraded to an expressway (though the actual route was not changed). The western half of the road was opened to traffic in 2013, while the eastern half was opened in 2020 and 2021. Chronology Construction of the first phase of the project was divided into two sections. Work on a 3.9 km stretch between ''Warszawa Lotnisko'' junction (linking to expressway S79) and ''Puławska'' junction at the eastern end of this phase of the project began in September 2009, while construction of the other, 11.1 km long section between the western ''Konotopa'' junction (linking the motorway A2 and the western portion of the ring road, ...

Audi S2
The Audi S2 is an Audi sports car, manufactured by the division of quattro GmbH (now Audi Sport GmbH) on the same platform as the Audi 80 (B4) in Neckarsulm, Germany, produced from 1991 to 1995. The Audi S2 is the first car in the Audi S series. In 1994, a more powerful Audi RS 2 Avant was released.

The S2 featured the well-proven 2.2-litre in-line five-cylinder 20-valve turbo petrol engine from the Audi 200 20V, which was a variant of the engine used in the Audi Qua ...

S2 Spreadsheet
S2 Spreadsheet was a Lotus 1-2-3 compatible spreadsheet developed by IBM in 1984. It had all the features of Lotus 1-2-3, plus it had an ability to connect to IBM mainframes via TCP/IP and pull data from IBM databases such as IBM DB2 and IBM SQL/DS. It also had features that allowed for easy visual connection between formulas and their dependencies - those features were later adopted by Lotus 1-2-3 and Microsoft Excel. S2 was developed almost concurrently with Lotus development of 1-2-3, and matched 1-2-3 feature for feature. The S2 program was used throughout IBM in 1980s and 1990s. In 1986 it caused a legal controversy within IBM because of then current look-and-feel lawsuits between Lotus and other companies, and most importantly because IBM was negotiating a high-profile deal with Lotus to market Lotus 1-2-3. According to a ''PC Week'' article of 1986 and a subsequent one in 2009, the sole author of this program was a developer in IBM Thomas J. Watson Research Center, Thomas Wa ...
