Enrico Fermi

Enrico Fermi (Italian: [enˈriko ˈfermi]; 29 September 1901 – 28 November 1954) was an Italian physicist, who created the world's first nuclear reactor, the Chicago Pile-1. He has been called the "architect of the nuclear age", and the "architect of the atomic bomb". He was one of the few physicists to excel both theoretically and experimentally. Fermi held several patents related to the use of nuclear power, and was awarded the 1938 Nobel Prize in Physics for his work on induced radioactivity by neutron bombardment and the discovery of transuranic elements. He made significant contributions to the development of quantum theory, nuclear and particle physics, and statistical mechanics.

Fermi's first major contribution was to statistical mechanics. After Wolfgang Pauli announced his exclusion principle in 1925, Fermi followed with a paper in which he applied the principle to an ideal gas, employing a statistical formulation now known as Fermi–Dirac statistics. Today, particles that obey the exclusion principle are called "fermions". Later Pauli postulated the existence of an uncharged invisible particle emitted along with an electron during beta decay, to satisfy the law of conservation of energy. Fermi took up this idea, developing a model that incorporated the postulated particle, which he named the "neutrino". His theory, later referred to as Fermi's interaction and still later as weak interaction, described one of the four fundamental forces of nature. Through experiments inducing radioactivity with recently discovered neutrons, Fermi discovered that slow neutrons were more easily captured than fast ones, and developed the Fermi age equation to describe this. After bombarding thorium and uranium with slow neutrons, he concluded that he had created new elements; although he was awarded the Nobel Prize for this discovery, the new elements were subsequently revealed to be fission products.

Enrico Fermi Nuclear Power Plant (Italy)

Enrico Fermi Nuclear Power Plant was a nuclear power plant at Trino (often referred to as ‘Trino Vercellese’, meaning ‘Trino in the Province of Vercelli’), in north-west Italy.

Consisting of one 260 megawatt pressurized water reactor (PWR), it operated from 1964 until 1990, when it was closed following the referendum of November 1987.

Closer to the power plant was also an experimental enrichment plant, EUREX, which was closed down in 1984.

Enrico Fermi Nuclear Generating Station

The Enrico Fermi Nuclear Generating Station is a nuclear power plant on the shore of Lake Erie near Monroe, in Frenchtown Charter Township, Michigan on approximately 1,000 acres. All units of the plant are operated by the DTE Energy Electric Company and owned (100 percent) by parent company DTE Energy. It is approximately halfway between Detroit, Michigan, and Toledo, Ohio. It is also visible from parts of Amherstburg and Colchester, Ontario as well as on the shore of Lake Erie in Ottawa County, Ohio. Two units have been constructed on this site. The first unit's construction started on August 4, 1956 and reached initial criticality on August 23, 1963, and the second unit received its construction permit on September 26, 1972. It reached criticality (head on) in June 21, 1985 and was declared commercial on November 18, 1988. The plant is connected to two single-circuit 345 kV Transmission Lines and 3 120 kV lines. They are operated and maintained by ITC Transmission.

Italy (ⁱ/ˈɪtəli/; Italian: Italia [iˈtaːlja]), officially the Italian Republic (Italian: Repubblica Italiana), is a unitary parliamentary republic in Europe. Italy covers an area of 301,338 km² (116,347 sq mi) and has a largely Mediterranean and temperate climate; due to its shape, it is often referred to in Italy as lo Stivale (the Boot). With 61 million inhabitants, it is the 4th most populous EU member state. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino and Vatican City.

Since ancient times, Greeks, Etruscans and Celts have inhabited the south, centre and north of the Italian Peninsula respectively. Rome ultimately emerged as the dominant power, conquering much of the ancient world and becoming the leading cultural, political, and religious centre of Western civilisation. The legacy of the Roman Empire is widespread and can be observed in the global distribution of civilian law, Republican governments, Christianity and the latin script.

Roman Italy

Roman Italy was created officially by the Roman Emperor Augustus with the Latin name Italia. It was the first time in history that the Italian peninsula (from the Alps to the Ionian Sea) was united under the same name. In the year 292, the three islands of Corsica, Sardinia and Sicily were added to Roman Italy by Emperor Diocletianus.

Characteristics

Italy (Italia in Latin and Italian) was the name of the administrative division of the Italian peninsula during the Roman era. It was not a province, but became the territory of the city of Rome, thus having a special status. Following the end of the Social War (91–88 BC), Rome had allowed its Italian allies (socii) full rights in Roman society and granted the Roman citizenship to all the Italic peoples.

After having been for centuries the heart of the Empire, from the 3rd century the government and the cultural center began to move eastward: first the Edict of Caracalla in 212 AD extended Roman citizenship to all free men within the imperial boundaries, then during Constantine's reign (306–337) the seat of the Empire was moved to Constantinople in 330 AD.

Italian wine

Italy is home to some of the oldest wine-producing regions in the world, and Italian wines are known worldwide for their broad variety. Italy, closely followed by France, is the world’s largest wine producer by volume. Its contribution is about 45–50 million hl per year, and represents about ⅓ of global production.Italian wine is exported around the world and is also extremely popular in Italy: Italians rank fifth on the world wine consumption list by volume with 42 litres per capita consumption. Grapes are grown in almost every region of the country and there are more than one million vineyards under cultivation.

Etruscans and Greek settlers produced wine in Italy before the Romans started their own vineyards in the 2nd century B.C. Roman grape-growing and winemaking was prolific and well-organized, pioneering large-scale production and storage techniques like barrel-making and bottling.

History

Although vines had been cultivated from the wild Vitis vinifera grape for millennia, it wasn't until the Greek colonization that wine-making flourished. Viticulture was introduced into Sicily and southern Italy by the Mycenaean Greeks, and was well established when the extensive Greek colonization transpired around 800 BC. It was during the Roman defeat of the Carthaginians (acknowledged masters of wine-making) in the 2nd century BC that Italian wine production began to further flourish. Large-scale, slave-run plantations sprang up in many coastal areas and spread to such an extent that, in AD 92, emperor Domitian was forced to destroy a great number of vineyards in order to free up fertile land for food production.
