900 (nine hundred) is the natural number following 899 and preceding 901. It is the square of 30 and the sum of Euler's totient function for the first 54 integers. In base 10 it is a Harshad number.Abu al-Wafa' Buzjani
Abū al-Wafāʾ, Muḥammad ibn Muḥammad ibn Yaḥyā ibn Ismāʿīl ibn al-ʿAbbās al-Būzjānī or Abū al-Wafā Būzhjānī (Persian: ابوالوفا بوزجانی or بوژگانی) (10 June 940 – 15 July 998) was a Persian mathematician and astronomer who worked in Baghdad. He made important innovations in spherical trigonometry, and his work on arithmetics for businessmen contains the first instance of using negative numbers in a medieval Islamic text.
He is also credited with compiling the tables of sines and tangents at 15 ' intervals. He also introduced the secant and cosecant functions, as well studied the interrelations between the six trigonometric lines associated with an arc. His Almagest was widely read by medieval Arabic astronomers in the centuries after his death. He is known to have written several other books that have not survived.Bretz Mill, California
Bretz Mill is an unincorporated community in Fresno County, California. It lies at an elevation of 3274 feet (998 m).Ducati 998
The Ducati 998, a successor to the Ducati 996 and the final variation on the Ducati 916, was produced in various models from 2002 to 2004. The new Testastretta engine shared many similarities with the previous Desmoquattro engine in the 996, although it was completely new from the crankshaft up. Testastretta means narrow head and refers to a complete redesign of the cylinder heads. The desmodromic valve actuation method was retained.
The 996 had a bore and stroke of 98.0 mm × 66.0 mm (3.86 in × 2.60 in). The bore and stroke of the 998 was more oversquare at 100.0 mm × 63.5 mm (3.94 in × 2.50 in). The included valve angle was reduced from 40 degrees on the 996 to 25 degrees on the 998. Valve sizes were increased, and the camshafts had slightly increased lift, but with shorter duration. Horsepower increased from 112 to 123.
The 998R and non US 998S models had different crankcases with a deep oil sump. The standard 998 had crankcases which were very similar to the previous Desmoquattro. The non US 998S as well as the 998R had revised cam profiles which provided more power than the standard 998. The 998R model used a 104.0 mm × 58.8 mm (4.09 in × 2.31 in) mm bore and stroke which actually displaced 999 cc, and was very similar to the engine used in the subsequent 999R model.
In 2001, Ducati introduced the 996R (see Ducati 996) with the 998 cc Testastretta engine. This bike was the true introduction of the Testastretta engine and the 998 model. The engine was similar to the 2002 non US 998S. Only 500 were sold which was all that were needed to homologate the bike to race in the World Superbike Championship. This bike won the World Superbike Championship in 2001 with rider Troy Bayliss. Michael Rutter won the Macau Grand Prix in 2002 and 2003.
A 2001 Ducati 996, in dark green, was featured in the 2003 movie The Matrix Reloaded. Ducati subsequently announced a limited edition of similar bikes for model year 2004 in a very dark green color, but as production of the 996 had since ceased, these were actually 998-series bikes.
The 998 officially ended production in 2004 with the release of the 998s FE ("Final Edition"). This bike was only available by special order, it was not available as a regular production model. They were available in Biposto and Monoposto(one or two seat) versions. It was largely similar to the US model 2002 998S (using the standard 998 engine but with uprated Ohlins suspension components and Brembo four-piston calipers).Gaussian units
Gaussian units constitute a metric system of physical units. This system is the most common of the several electromagnetic unit systems based on cgs (centimetre–gram–second) units. It is also called the Gaussian unit system, Gaussian-cgs units, or often just cgs units. The term "cgs units" is ambiguous and therefore to be avoided if possible: cgs contains within it several conflicting sets of electromagnetism units, not just Gaussian units, as described below.
The most common alternative to Gaussian units are SI units. SI units are predominant in most fields, and continue to increase in popularity at the expense of Gaussian units. (Other alternative unit systems also exist, as discussed below.) Conversions between Gaussian units and SI units are not as simple as normal unit conversions. For example, the formulas for physical laws of electromagnetism (such as Maxwell's equations) need to be adjusted depending on what system of units one uses. As another example, quantities that are dimensionless (loosely "unitless") in one system may have dimension in another.German submarine U-998
German submarine U-998 was a Type VIIC/41 U-boat of Nazi Germany's Kriegsmarine during World War II.
She was ordered on 14 October 1941, and was laid down on 5 December 1942, at Blohm & Voss, Hamburg, as yard number 198. She was launched on 18 August 1943, and commissioned under the command of Kapitänleutnant Hans Fiedler on 7 October 1943.Kodjoani-léoura
Kodjoani-léoura is a village in the Bogandé Department of Gnagna Province in eastern Burkina Faso. The village has a population of 998.List of compositions by Franz Schubert
Franz Schubert (31 January 1797 – 19 November 1828), a late Classical – early Romantic Viennese composer, left a very extended body of work notwithstanding his short life. He wrote some 1500 items, or, when collections, cycles and variants are grouped, some thousand compositions. The largest group are his over six hundred Lieder for solo voice and piano. He composed nearly as many piano pieces, and further some 150 part songs, some 40 liturgical compositions (including several masses) and around 20 stage works like operas and incidental music. His orchestral output includes a dozen symphonies (seven completed) and several overtures. Schubert's chamber music includes over 20 string quartets, and several quintets, trios and duos.Otto Erich Deutsch compiled the first comprehensive catalogue of Schubert's works and published it in 1951 as Schubert: Thematic Catalogue of all his Works in Chronological Order. A revised edition appeared in German in 1978. Later editions of the catalogue contained minor updates.Publication of Schubert's compositions started during his lifetime, by opus number. After the composer's death, posthumous opus numbers continued to be assigned to new publications of his work until 1867 (Op. post. 173). In the meanwhile also publications without opus number had started, for instance, from shortly after the composer's death, many songs in Diabelli's fifty "Nachlaß-Lieferung" (instalment from the heritage) editions.There are two attempts to publish everything Schubert has composed in a single edition:
From 1884 to 1897 Breitkopf & Härtel published twenty-two series of Franz Schubert's Werke: Kritisch durchgesehene Gesammtausgabe, known as the "Alte Gesamt-Ausgabe" (AGA, the former complete edition). From 1965 Dover Publications started to reprint this edition, and later it was made available at the IMSLP website.
The Neue Schubert-Ausgabe (NSA), also known as the New Schubert Edition (NSE), is published by Bärenreiter (Kassel). It proposes around eighty-three volumes, in eight series. Publication of all volumes has been scheduled to conclude in 2016. Plans for this edition began as early as 1963, with the foundation of the International Schubert Society, headquartered at the University of Tübingen, Germany.Websites such as Schubert Online (schubert-online.at) provide facsimiles (scans) of Schubert's autographs and of other manuscripts and early editions of his work. Texts of Schubert's vocal music can be published without the music, for instance his Lieder (songs) at the LiederNet Archive website.List of fastest production motorcycles
The fastest production motorcycle for a given year is the unmodified motorcycle with the highest tested top speed that was manufactured in series and available for purchase by the general public. Modified or specially produced motorcycles are a different class, motorcycle land-speed record. Unlike those records, which are officially sanctioned by the Fédération Internationale de Motocyclisme (FIM), production model tests were conducted under a variety of unequal or undefined conditions, and tested by numerous different sources, mainly motorcycling magazines. This has led to inconsistent and sometimes contradictory speed statistics from various sources.List of state highways in Maryland shorter than one mile (900–999)
The following is a list of state highways in Maryland shorter than one mile (1.6 km) in length with route numbers between 900 and 999. Most of these highways act as service roads, old alignments of more prominent highways, or connectors between one or more highways. Many of these highways are unsigned and have multiple segments with the same number. Several of these highways have their own articles; those highways are summarized here and a link is provided to the main article. This list does not include highways where at least one highway of that number is at least one mile in length. All highways at least one mile in length have their own article. The highways shorter than one mile with the same number are covered in the main article for the highway.Little Dixie, California
Little Dixie is a former settlement in Kern County, California. It was located on Little Dixie Wash 17 miles (27 km) north-northeast of Cross Mountain, at an elevation of 3274 feet (998 m). Little Dixie still appeared on maps as of 1915.Prelude, Fugue and Allegro in E-flat major, BWV 998
Prelude, Fugue, and Allegro in E-flat major, BWV 998, is a musical composition written by Johann Sebastian Bach for Lute or Harpsichord.
The piece was written around 1735. The original manuscript with the title "Prelude pour la Luth. ò Cembal. Par J.S. Bach" was sold at Christie's on July 13, 2016 for £2,518,500.Sherborne Abbey
The Abbey Church of St Mary the Virgin at Sherborne in the English county of Dorset, is usually called Sherborne Abbey. It has been a Saxon cathedral (705–1075), a Benedictine abbey (998–1539), and since 1539, a parish church of the Church of England.Siege of Zadar (998)
The Siege of Zadar in 998 was part of the third Croatian–Bulgarian war and one of the last military conflicts between Croatian forces of king Svetoslav Suronja (r. 997–1000), supported by Venice and the Byzantine Empire, and the army of emperor Samuil (r. 997–1014), who launched a large-scale Bulgarian military campaign against the Kingdom of Croatia.
Samuil's army besieged the fortified city of Zadar in order to aid the king's rebel brothers Krešimir and Gojslav, who asked Samuil to come and help them to remove Svetoslav Suronja from the Croatian throne. The siege was unsuccessful and Samuil's forces withdrew in the direction of Croatian hinterland and Bosnia, finally tracing their way back home.Sigfried, Count of the Ardennes
Sigfried (or Siegfried) (c. 922 – 28 October 998) was count of the Ardennes and the first person to rule Luxembourg. He was an advocate of the abbeys of St. Maximin in Trier and Saint Willibrord in Echternach. He may have been the son of Count Palatine Wigeric of Lotharingia and Cunigunda. He was the founder of the House of Luxembourg, a branch of the House of Ardennes.Sisinnius II of Constantinople
Sisinnius II (Greek: Σισίνιος Β΄, Sisinios B'; ? – 24 August 998) became Ecumenical Patriarch of Constantinople in 996 and held the post until his death in 999.
He was extremely well educated and had been honoured with the office of magistros. His patriarchate was characterised by the facing of flock issues, issues about wedding and divorce, but also by issues about the extension of the Bishop of Constantinople. He died on 24 August 999. His successor was Sergius II of Constantinople.Sunnyside, Mendocino County, California
Sunnyside is a former settlement in Mendocino County, California. It was located 10 miles (16 km) north-northeast of Covelo, at an elevation of 3274 feet (998 m). Sunnyside still appeared on maps as of 1926.Telephone numbers in Uzbekistan
