Alessandro Giuseppe Antonio Anastasio Volta was an Italian physicist and chemist who was a pioneer of electricity and power, and is credited as the inventor of the electric battery and the discoverer of methane. He invented the voltaic pile in 1799, and reported the results of his experiments in a two-part letter to the president of the Royal Society, which was published in 1800. With this invention, Volta proved that electricity could be generated chemically and debunked the prevalent theory that electricity was generated solely by living beings. Volta's invention sparked a great amount of scientific excitement and led others to conduct similar experiments, which eventually led to the development of the field of electrochemistry.
The krona is the currency of the Kingdom of Sweden. It is one of the currencies of the European Union. Both the ISO code "SEK" and currency sign "kr" are in common use for the krona; the former precedes or follows the value, the latter usually follows it but, especially in the past, it sometimes preceded the value. In English, the currency is sometimes referred to as the Swedish crown, as krona means "crown" in Swedish. The Swedish krona was the ninth-most traded currency in the world by value in April 2016.
The voltaic pile was the first electrical battery that could continuously provide an electric current to a circuit. It was invented by Italian chemist Alessandro Volta, who published his experiments in 1799. Its invention can be traced back to an argument between Volta and Luigi Galvani, Volta's fellow Italian scientist who had conducted experiments on frogs' legs. Use of the voltaic pile enabled a rapid series of other discoveries, including the electrical decomposition (electrolysis) of water into oxygen and hydrogen by William Nicholson and Anthony Carlisle (1800), and the discovery or isolation of the chemical elements sodium (1807), potassium (1807), calcium (1808), boron (1808), barium (1808), strontium (1808), and magnesium (1808) by Humphry Davy.
Como is a city and comune (municipality) in Lombardy, Italy. It is the administrative capital of the Province of Como.
The forint is the currency of Hungary. It was formerly divided into 100 fillér, but fillér coins are no longer in circulation. The introduction of the forint on 1 August 1946 was a crucial step in the post-World War II stabilisation of the Hungarian economy, and the currency remained relatively stable until the 1980s. Transition to a market economy in the early 1990s adversely affected the value of the forint; inflation peaked at 35% in 1991. Between 2001 and 2022, inflation was in single digits, and the forint has been declared fully convertible. In May 2022, inflation reached 10.7% amid the Russian invasion of Ukraine and economic uncertainty. As a member of the European Union, the long-term aim of the Hungarian government may be to replace the forint with the euro, although under the current government there is no target date for adopting the euro.
The Romanian leu is the currency of Romania. It is subdivided into 100 bani, a word that also means "money" in the Romanian language.
The birr is the primary unit of currency in Ethiopia. It is subdivided into 100 santims.
The Mole Antonelliana is a major landmark building in Turin, Italy, named after its architect, Alessandro Antonelli. A mole in Italian is a building of monumental proportions.
The lira was the currency of Italy between 1861 and 2002. It was introduced by the Napoleonic Kingdom of Italy in 1807 at par with the French franc, and was subsequently adopted by the different states that would eventually form the Kingdom of Italy in 1861. It was subdivided into 100 centesimi, which means "hundredths" or "cents". The lira was also the currency of the Albanian Kingdom from 1941 to 1943.
The Belgian franc was the currency of the Kingdom of Belgium from 1832 until 2002 when the euro was introduced. It was subdivided into 100 subunits, each known as a centiem in Dutch, or centime in French and German.
The Guinean franc is the currency of Guinea. It is subdivided into one hundred centimes, but no centime denominations were ever issued.
Batteries provided the main source of electricity before the development of electric generators and electrical grids around the end of the 19th century. Successive improvements in battery technology facilitated major electrical advances, from early scientific studies to the rise of telegraphs and telephones, eventually leading to portable computers, mobile phones, electric cars, and many other electrical devices.
The Banknote Museum of Alpha Bank is a museum located in Corfu, Greece.
Banknotes of the euro, the common currency of the eurozone, have been in circulation since the first series was issued in 2002. They are issued by the national central banks of the Eurosystem or the European Central Bank. The euro was established in 1999, but "for the first three years it was an invisible currency, used for accounting purposes only, e.g. in electronic payments". In 2002, notes and coins began to circulate. The euro rapidly took over from the former national currencies and slowly expanded around the European Union.
The ten euro note (€10) is the second-lowest value euro banknote and has been used since the introduction of the euro in 2002. The note is used in the 25 countries that have it as their sole currency, which countries have a total population of about 350 million currently. In July 2024, there were approximately 3 055 000 000 ten euro banknotes in circulation around the eurozone. It is the fourth most widely circulated denomination, accounting for 10.2% of the total banknotes. Estimates suggest that the average life of a ten euro banknote is about 1.5 years before it is replaced due to wear.
The twenty euro note (€20) is the third-lowest value euro banknote and has been used since the introduction of the euro in 2002. The note is used in the 25 countries that have it as their sole currency, which countries have a total population of about 350 million currently. In July 2024, there were approximately 4,818,000,000 twenty euro banknotes in circulation around the eurozone. It is the second most widely circulated denomination, accounting for 16.3% of the total banknotes. Estimates suggest that the average life of a twenty euro banknote is about two years before it is replaced due to wear.
The fifty euro note (€50) is one of the middle value euro banknotes and has been used since the introduction of the euro in 2002. The note is used in the 25 countries that have it as their sole currency, which countries have a total population of about 350 million currently. In July 2024, there were about 14,712,000,000 fifty euro banknotes in circulation in the eurozone. It is by far the most widely circulated denomination, accounting for almost half (49.0%) of the total banknotes. Estimates suggest that the average life of a fifty euro banknote is about four years before it is replaced due to wear.
The five-hundred-euro note (€500) is the highest-value euro banknote; it was produced between the introduction of the euro in 2002 until 2019. Since 27 April 2019, the banknote has no longer been issued by central banks in the euro area, but it continues to be legal tender and can be used as a means of payment.
Life Electric is a contemporary sculpture, dedicated to the physicist Alessandro Volta (1745–1827). Completed in 2015 it is located in Como, Italy. Life Electric was designed by Daniel Libeskind, and was a gift to Como, the city where the architect located his “Summer Session” school of architecture, in 1988. The sculpture was commissioned by the non profit association “Gli amici di Como”. The design of the fountain illustrates the evolution of modern architecture that took place over the period from 1920s to modern days, with the emergence of Rationalism. Libeskind's creation has carried on the tradition of contemporary art in Como, and raised its profile.
