Johann Sebastian Bach (31 March [O.S. 21 March] 1685 – 28 July 1750) was a German composer and musician of the Baroque period. He enriched established German styles through his skill in counterpoint, harmonic and motivic organisation, and the adaptation of rhythms, forms, and textures from abroad, particularly from Italy and France. Bach's compositions include the Brandenburg Concertos, the Goldberg Variations, the Mass in B minor, two Passions, and over three hundred cantatas of which around two hundred survive. His music is revered for its technical command, artistic beauty, and intellectual depth.

Bach's abilities as an organist were highly respected during his lifetime, although he was not widely recognised as a great composer until a revival of interest and performances of his music in the first half of the 19th century. He is now generally regarded as one of the greatest composers of all time.

Life

Bach was born in Eisenach, in the duchy of Saxe-Eisenach, into a great musical family. His father, Johann Ambrosius Bach, was the director of the town musicians, and all of his uncles were professional musicians. His father probably taught him to play the violin and harpsichord, and his brother, Johann Christoph Bach, taught him the clavichord and exposed him to much contemporary music. Apparently at his own initiative, Bach attended St. Michael's School in Lüneburg for two years. After graduating, he held several musical posts across Germany: he served as Kapellmeister (director of music) to Leopold, Prince of Anhalt-Köthen, and as Thomaskantor in Leipzig, a position of music director at the main Lutheran churches and educator at the Thomasschule. He received the title of "Royal Court Composer" from Augustus III in 1736. Bach's health and vision declined in 1749, and he died on 28 July 1750.

As of September 2015, the city had an estimated population of 62,686 and a population density of 507 persons per km². Its total area was 123.64 square kilometres (47.74 sq mi). The city has a large expatriate population from Brazil, and many of the city signs are in both Japanese and Portuguese.

Geography

Jōsō is located in southwestern Ibaraki Prefecture, approximately 50 kilometers north of central Tokyo. Most of the city is flat, with an average elevation of 10-20 meters above sea level. The Kinugawa River flows through the city.

History

The town of Mitsukaidō was established within Toyoda District with the creation of the municipalities system on April 1, 1889. The area was transferred to Yūki District in 1894. On July 10, 1954 Mitsukaidō merged with the villages of Sugawara, Ohanawa, Mitsuma, Goka, Ono and Sakate, and was elevated to city status. It further annexed the villages of Sugao and Uchimoriya on April 1, 1956.

Jūsō (十三, lit. "Thirteen") is an area in Yodogawa-ku in north central Osaka, Japan.

The core of the area is Jūsō Station, the hub station of the Hankyu Railway system. The area typifies the unique culture of Osaka. Situated across the Yodo River from central Osaka, Jūsō is centrally located for easy access by Hankyu Railway lines to other major Kansai cities: 24 minutes to Kobe (Sannomiya Station) to the west and 40 minutes to Kyoto (Kawaramachi Station) to the northeast.

Predominantly known as the pink area of Osaka, Jūsō has a robust red light district area in the Hommachi West area.

Jūsō is also famous for its wide variety of high quality classic Osaka cuisine featuring okonomiyaki, negiyaki, and takoyaki shops.

In August every year, a massive fireworks celebration takes place beside the Yodo River; the people who attend this celebration often wear traditional yukatas and wooden sandals.

History

The name Jūsō is written with the kanji for "thirteen." One theory as the origin of the name states that it was originally the thirteenth stop on the Yodo River going from Kyoto to Osaka Bay. A less popular theory holds that the name originated in numbering under the old jorisei (条里制) land allocation system.

The watt (symbol: W) is a derived unit of power in the International System of Units (SI), named after the Scottish engineer James Watt (1736–1819). The unit is defined as joule per second and can be used to express the rate of energy conversion or transfer with respect to time. It has dimensions of L²MT⁻³.

Examples

When an object's velocity is held constant at one meter per second against constant opposing force of one newton the rate at which work is done is 1 watt.

In terms of electromagnetism, one watt is the rate at which work is done when one ampere (A) of current flows through an electrical potential difference of one volt (V).

Two additional unit conversions for watt can be found using the above equation and Ohm's Law.

Where ohm () is the SI derived unit of electrical resistance.
