Arnold Rosé was born in Iaşi (Jassy) in what is now Romania. His family was Jewish. Their name at that time was Rosenblum. He had three brothers. All four boys were musical and so his parents decided to move to Vienna which was a big city in Austria where there was lots of music. Arnold’s father was a carriage builder. In those days people often travelled by horse and cart. His father made good quality carriages and he made plenty of money from his business.
When Arnold was seven he started music lessons. When he was ten he was good enough to study the violin at the Vienna Conservatorium which was a special school for musical pupils.
In 1881 he played a violin solo with a famous orchestra and famous conductor: the Vienna Philharmonic under Hans Richter. The piece he played was the Violin Concerto by Otto Goldmark. Soon he was offered the job of orchestral leader. This was a very important position for such a young man. He stayed in that job for 50 years!
Rosé did other things as well as playing with the orchestra. He gave violin lessons to talented pupils. He like to play string quartets and he got together with three other players to make up the Rosé Quartet. They were very good and for more than half a century people said they were the best string quartet in Europe. Arnold’s brother Eduard was the cellist in the quartet. They played works by lots of composers, especially Haydn, Mozart and Ludwig van Beethoven. Rosé knew the composer Johannes Brahms and they played some of Brahms’s compositions when they had only just been written, e.g. the clarinet quintet (for clarinet and string quartet). The Rosé Quartet also knew the composer Schoenberg and helped him to get well known by playing his music.
Another composer Rosé knew very well was Gustav Mahler. Mahler had two sisters. Arnold Rosé married one of them, and his brother Eduard married the other.
Arnold was kept very busy at his job as leader of the orchestra. The orchestra played in the concert hall as well as for the opera. At one special concert lots of flowers and plants had been brought in to the concert hall. The orchestra were busy playing when Arnold noticed people were looking at his shoes. He thought maybe he had an odd pair of shoes on. When he looked down at his feet he saw a mouse sitting there.
Arnold and his wife Justine had a son and a daughter who both became musicians. They had plenty of money to live quite comfortably. He was given the title of Royal and Imperial Court Musician, and he had a special court carriage to take him to the opera. He also had a carriage of his own with a footman in livery (uniform) to drive him about.
However, things changed in 1938. The Nazis took over Austria and made life very difficult for Jewish people. They were in great danger. In the autumn his wife died and Arnold had to save his life by going to England. He stayed there for most of his remaining years. He died in London.

Pontiac Silverdome
The Pontiac Silverdome is a domed stadium in the town of Pontiac, Michigan, near Detroit. It opened in 1975 and closed in 2007. The largest crowds to come to the stadium were for WrestleMania III on March 29, 1987, where the main event was a match between Hulk Hogan and André the Giant. The crowd attendance for that night reached 93,173, which is also the record for indoor attendance. The Detroit Lions NFL team played at the stadium from 1975 until 2001.

Estonian language
The Estonian language () is a Uralic language. It is mainly spoken in Estonia. The Estonian language is similar to Finnish and is one of the few national languages of Europe not to be an Indo-European language.
The Estonian alphabet uses the Latin alphabet. It has many vowels, including Ö, Ä, Õ and Ü.
It has been influenced by and adopted many words from German and Swedish. Estonian language also has different dialects.
Chromosome
The chromosomes of a cell are in the cell nucleus. They carry the genetic information. Chromosomes are made up of DNA and protein combined as chromatin. Each chromosome contains many genes. Chromosomes come in pairs: one set from the mother; the other set from the father. Cytologists label chromosomes with numbers.
Chromosomes are present in every cell nucleus with very few and special exceptions. This means they are found in all eukaryotes, since only eukaryotes have cell nuclei. When eukaryote cells divide, the chromosomes also divide.
When a somatic (body) cell (such as a muscle cell) divides, the process is called mitosis. Before mitosis, the cell copies all the chromosomes and then it can divide. When they duplicate, chromosomes look like the letter "X". When they are doubled, the two halves are called chromatids (see diagram). The chromatids are joined at the centromere.
There are 46 chromosomes in a human, 23 pairs. Everyone has a set of chromosomes from their father and a matching set from their mother. They include a pair of sex chromosomes. The mother's eggs always contain an X chromosome, while the father's sperm contains either a Y chromosome or an X chromosome. That determines the sex of the child. To produce sex cells (gametes), the stem cells go through a different division process called meiosis. This reduces the 23 pairs (diploid) to 23 singles (haploid). These, when combined by fertilisation, produce the new set of 23 pairs.
Different animals have different numbers of chromosomes. If a person does not have the usual number of chromosomes, they may die or have one or more peculiarities. For example, they might get a genetic disorder like Down syndrome (extra chromosome 21) and Klinefelter syndrome (a male with two X chromosomes). Some genetic disorders are more common than others.
Polytene chromosomes are over-sized chromosomes which have developed from standard chromosomes. Specialized cells undergo repeated rounds of DNA replication without cell division (endomitosis). Polytene chromosomes form when multiple rounds of replication produce many sister chromatids that are stuck together in parallel.
Polytene chromosomes are found in "Drosophila" species and in nonbiting midges. They also occur in arthropods of the class Collembola, Ciliate protozoa, early stages of mammalian embryos, and suspensor cells in plants.
Polytene cells have a metabolic function. Multiple copies of genes allows a high level of gene expression. In "Drosophila", for example, the chromosomes of the larval salivary glands undergo many rounds of endoreduplication. This produces large amounts of glue-like mucous (“glue”) before pupation.
Chromosome puffs (seen in diagram) are diffused uncoiled regions of the polytene chromosome. They are sites of active transcription.
Giovanni Gabrieli
Giovanni Gabrieli (probably born Venice (date unknown), about 1553 - 57; died 21 August 1612, in Venice) was an Italian organist and composer.
He was very famous in his day and composed a great deal of church music; motets and madrigals. He lived at the end of the Renaissance period and beginning of the Baroque.
About 1575, Giovanni began working for Orlando di Lasso at the Bavarian court, as his uncle Andres Gabrieli had before him. Little is known of his time in Munich, and he left in 1579 after the death of his patron, Duke Albrecht. There is no record of Gabrieli's activities until 1584 when he'd returned to Venice. That year he replaced organist Claudio Merulo at Basilica di San Marco, church of Venice's patron saint. Due to Merulo's resignation, a contest was eventually held January 1, 1585 to fill his post, which Gabrieli won, having already occupied the position anyway. Giovanni and his uncle, who had raised him and taught him music, worked together only a short time at the church before Andres died in August 1585. Giovanni held his post until he died in 1612.
Also in 1585 Giovanni had been appointed as organist of Scuola Grande di San Rocco, where he composed ceremonial music.
