Berlin vs Pearl

Informations

Berlin (; German: [bɛʁˈliːn] (listen)) is the capital and biggest city of Germany by both area and population. Its 3,769,495 inhabitants as of 31 December 2019 make it the most populous city of the European Union, according to population within city limits. The city is also one of Germany's 16 federal states. It is surrounded by the state of Brandenburg, and contiguous with Potsdam, Brandenburg's capital. The two cities are at the middle of the Berlin-Brandenburg capital region, which is, with about six million inhabitants and an area of over 30,000 km2, Germany's third-largest metropolitan region after the Rhine-Ruhr and Rhine-Main areas. Berlin straddles the banks of the River Spree, which flows to the River Havel (a tributary of the River Elbe) from the western borough of Spandau. Among the city's main topographical features are the numerous lakes in the western and southeastern boroughs formed by the Spree, Havel, and Dahme rivers (the biggest of which is Lake Müggelsee). Due to its location in the European Plain, Berlin is influenced by a temperate seasonal climate. About one-third of the city's area is composed of woods, parks, gardens, rivers, canals and lakes. The city lies in the Central German dialect region, the Berlin dialect being a version of the Lusatian-New Marchian dialects. First documented in the 13th century and situated at the crossing of two important historic trade routes, Berlin became the capital of the Margraviate of Brandenburg (1417--1701), the Kingdom of Prussia (1701--1918), the German Empire (1871--1918), the Weimar Republic (1919--1933), and the Third Reich (1933--1945). Berlin in the 1920s was the third-largest municipality in the world. Following World War II and its subsequent occupation by the victorious nations, the city was divided; West Berlin became a de facto West German exclave, surrounded by the Berlin Wall (1961--1989) and East German territory. East Berlin was declared capital of East Germany, while Bonn became the West German capital. Following German reunification in 1990, Berlin once again became the capital of all of Germany. Berlin is a world city of culture, politics, media and science.

Its economy relies on high-tech firms and the service industry, encompassing a diverse selection of innovative industries, research facilities, media corporations and conference venues. Berlin functions as a continental hub for air and rail traffic and has a highly complex public transportation network. The metropolis is a popular tourist destination. Significant industries also include IT, pharmaceuticals, biomedical engineering, clean tech, biotechnology, construction and electronics. Berlin is home to world-renowned universities like the Humboldt Universität zu Berlin (HU Berlin), the Technische Universität Berlin (TU Berlin), the Freie Universität Berlin (Free University of Berlin), the Universität der Künste (University of the Arts, UdK), ESMT Berlin and the Berlin School of Economics and Law. Its Zoological Garden is the most visited zoo in Europe and one of the most popular worldwide. With the world's oldest large-scale film studio complex, Berlin is an increasingly popular location for international film productions. The city is well known for its festivals, diverse architecture, nightlife, modern arts and a very high quality of living. Since the 2000s Berlin has seen the development of a cosmopolitan entrepreneurial scene.Berlin Comprises three World Heritage Sites: Museum Island; the Palaces and Parks of Potsdam and Berlin; and the Berlin Modernism Housing Estates. Other landmarks include the Brandenburg Gate, the Reichstag building, Potsdamer Platz, the Memorial to the Murdered Jews of Europe, the Berlin Wall Memorial, the East Side Gallery, the Berlin Victory Column, Berlin Cathedral and the Berlin Television Tower, the tallest structure in Germany. Berlin has numerous museums, libraries, galleries, orchestras and sporting events.

A pearl is a hard, glistening object produced within the soft tissue (specifically the mantle) of a living shelled mollusk or another animal, such as fossil conulariids. Just like the shell of a mollusk, a pearl is composed of calcium carbonate (mainly aragonite or a mixture of aragonite and calcite) in minute crystalline form, which has deposited in concentric layers. The ideal pearl is perfectly round and smooth, but many other shapes, known as baroque pearls, can occur. The finest quality of natural pearls have been highly valued as gemstones and objects of beauty for many centuries. Because of this, pearl has become a metaphor for something rare, fine, admirable and valuable. The most valuable pearls occur spontaneously in the wild, but are extremely rare. These wild pearls are referred to as natural pearls. Cultured or farmed pearls from pearl oysters and freshwater mussels make up the majority of those currently sold.

Imitation pearls are also widely sold in inexpensive jewelry, but the quality of their iridescence is usually very poor and is easily distinguished from that of genuine pearls. Pearls have been harvested and cultivated primarily for use in jewelry, but in the past were also used to adorn clothing. They have also been crushed and used in cosmetics, medicines and paint formulations. Whether wild or cultured, gem-quality pearls are almost always nacreous and iridescent, like the interior of the shell that produces them. However, almost all species of shelled mollusks are capable of producing pearls (technically "calcareous concretions") of lesser shine or less spherical shape. Although these may also be legitimately referred to as "pearls" by gemological labs and also under U.S. Federal Trade Commission rules, and are formed in the same way, most of them have no value except as curiosities.
