Weber was not only a great composer, but a very skilled pianist and conductor. He wrote a very large number of works including cantatas and songs, but most of these are not often heard today. One of his most popular works is called "Invitation to the Dance". It was written for piano, but later Hector Berlioz arranged it for orchestra and this is how it is often heard nowadays.
Weber wrote two Concertos for clarinet and orchestra and also a Concertino (a small concerto in one movement). Another one-movement concerto was the "Konzertstück in F minor" for piano and orchestra. His opera "Der Freischütz " is probably his best work, and the overture is often heard separately as a concert piece. The story of the opera is full of magic. It is written in German and has some spoken words as well as sung music (this kind of opera was called a Singspiel). This opera in particular influenced Richard Wagner who developed German opera in the 19th century.

Ter Hachatrjan
Ter Hachatrjan () is the name of a Russian noble family during the 18th century.
Duke Aleksandr Ter Hachatrjan (around 1870–1917) was born as an Armenian aristocrat. He also belonged to the Russian nobility. He married a Greek duchess named Sofia. They had two sons together: Duke Anton Aleksandrovich (around 1891–1950) and Duke Bagrat Aleksandrovich (1892–1981).
During the revolution in Petrograd in 1917, Duke Aleksandr and his wife were killed by the Bolsheviks. Their two sons then escaped from Petrograd and went to the Caucasus. Bagrat was separated from his brother Anton.
Anton later appeared in the city Rostov on Don. He married Barinova Elena Aleksandrovna. They had no children.
Bagrat got married to Elizaveta Danilovna in 1923. They had a daughter and a son together: Emma Bagratovna (1924–2005) and Yuri Bagratovich. Bagrat divorced Elizaveta in 1927. In the year 1932, Bagrat married Petrachuk Olga Alekseevna, the daughter of merchant from Ukraine. They had two daughters together: Amalia Bagratovn (born 1933) and Inessa Bagratovna (born 1936). Bagrat was an officer in the Imperial Army. He was awarded the Military Order of the Saint Grand Martyr and the Triumphant George. It was one of the highest awards of the Russian Empire.
The Ter Hachatrjan family fell under the repression of NKVD in 1937. They were arrested and placed in jail in the city of Goris. Bagrat Aleksandrovich was accused of taking part in the execution of 26 Baku Commissars. As was the case with all noble families, Duke Bagrat was found guilty of treason and was declared an enemy of the Soviet State. Under the pressure of the government, Duke Bagrat had to stop using his title and rid himself of all his possessions that were brought from Petrograd. The family were then given amnesty.
After, that Bagrat Aleksandrovich worked as a director and actor of movies in Armenia. He died in Kafan in 1981.
Amalia Bagratovna married Saidoff N. S., a rich man from Baku. They had two children together: Saidoff A. N. (born 1961) and Saidoff S. C. N. (born 1963).
Since this time, all the descendents of the Ter Hachatrjan family are named as Saidoff–Ter Hachatrjan.
Ter-Khachatryan or Ter-Khachatryants is an Armenian family, known from the XVIII century. First well-known representative of this family - Daniel-Bek of Sassun Ter Khachatryan or Ter Khachatryan (born in province Sassun or Sason of Western Armenia) about 1785 - died in (town Mush of Western Armenia), in 1829). He was originally an Armenian nobleman, descendant of South or Sout-West branch, i.e. Tarawn-Aldznik branch of Bagratouni or Bagratids dynasty (Actually son of the Armenian priest of Khachatur and, who was a descendant of the Armenian princely dynasty Bagratid, the south or south-west branch of them in 13-14 centuries saved shallow possessions in the district of Sassun or Sason of Western Armenia and province of Aldznik, as well as in the district of Mush in the province of Tarawn of Western Armenia). As a result of the hard oppressions of Kurd feudal lords, Daniel-Bek of Sassun transmigrated from Sason to the town Mush, where his family had a house in the Armenian quarter of Berd, near the church Saint Marineh. The eldest son of Daniel-Bek of Sassun, Avdal bek Ter-Khachatryants (1805-1867) also lived in Mush. The son of Avdal bek Ter-Khachatryants and grandson of Daniel-Bek of Sassun was Jakob bek (Hakob bek) Ter-Khachatryants. The son of Jakob bek (Hakob bek) Ter-Khachatryants was Khachatur-Bek of Mush (the town Mush of Western Armenia), who lived in the first half of the 19th century. Khachar and Garegin Khachatryan, both prominent Armenian artists and ideologists of Armenian liberation movement, were descendents of his House.
Turbine
A turbine is an engine that turns fluid movement into energy.
Simple turbines have a shaft with a blade on it. Moving fluids, such as water or air, push the blades so that they turn around with the shaft. The turning movement is most often used to turn a generator. Early turbine examples are windmills and water wheels. Turbine blades can also be turned to move a fluid. This is how simple propeller airplanes work.
A casing can be placed around the turbine to control the movement of the fluid.

Electric power
Electric power is defined as the power dissipated by an electric circuit. Electric power is a measurement of the rate at which energy is used over a period of time. The SI unit for power is the watt, the unit for energy is the joule, and the unit for time is the second.
For a direct current circuit, electric power equals the electric current multiplied by the voltage.
When electric current flows through a circuit, it is slowed down by the resistance in the circuit. Devices can convert this current to useful forms of work, such as heat radiation, light emission, mechanical motion, or acoustic vibrations.

Head (hydraulic)
Hydraulic head is a specific measurement of water pressure or total energy per unit weight above a datum.
It is usually measured as a water surface elevation, expressed in units of length, but represents the energy at the entrance (or bottom) of a piezometer. In an aquifer, it can be calculated from the depth to water in a piezometric well (a specialized water well), and given information of the piezometer's elevation and screen depth.
Even though it is conventional to use gauge pressure in the calculation of hydraulic head, it is more correct to use total pressure (gauge pressure + atmospheric pressure), since this is truly what drives groundwater flow. Often detailed observations of barometric pressure are not available at each well through time, so this is often disregarded (contributing to large errors at locations where hydraulic gradients are low or the angle between wells is acute.)
Hydraulic head is a measure of energy, and has many analogs in physics and chemistry, where the same mathematical principles and rules apply:
