Tuscany
Tuscany ( ; it, Toscana ) is a Regions of Italy, region in central Italy with an area of about and a population of about 3.8 million inhabitants. The regional capital is Florence (''Firenze''). Tuscany is known for its landscapes, history, artistic legacy, and its influence on high culture. It is regarded as the birthplace of the Italian Renaissance and of the foundations of the Italian language. The prestige established by the Tuscan dialect's use in literature by Dante Alighieri, Petrarch, Giovanni Boccaccio, Niccolò Machiavelli and Francesco Guicciardini led to its subsequent elaboration as the language of culture throughout Italy. It has been home to many figures influential in the history of art and science, and contains well-known museums such as the Uffizi and the Palazzo Pitti. Tuscany is also known for its wines, including Chianti, Vino Nobile di Montepulciano, Morellino di Scansano, Brunello di Montalcino and white Vernaccia di San Gimignano. Having a strong linguisti ...

Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scoglio D'Africa
The Scoglio d'Africa (or Scoglio d'Affrica) also named Formica di Monte Cristo ("Monte Cristo's Ant"), is a solitary small skerry belonging to the Tuscan Archipelago located in open sea between the Tyrrhenian Sea and the Corsica Channel. It is located west of the Island of Montecristo, south of Pianosa Island and east of Corsica. Administratively it belongs to the municipality of Portoferraio. It is also part of the Tuscan Archipelago National Park. Description Regarding its size and its shape, it can be considered to all effects an emergent rock in a stretch of shallow sea. It has a rounded contour with the diameter of , an area of and an altitude of only above sea level depending from the tides and the waves. Geologically the skerry belongs to a submarine ridge starting few miles east of Capraia and it extends toward south up to reach Pianosa.

Tyrrhenian Sea
The Tyrrhenian Sea (; it, Mar Tirreno , french: Mer Tyrrhénienne , sc, Mare Tirrenu, co, Mari Tirrenu, scn, Mari Tirrenu, nap, Mare Tirreno) is part of the Mediterranean Sea off the western coast of Italy. It is named for the Tyrrhenian people identified with the Etruscans of Italy. Geography The sea is bounded by the islands of Corsica and Sardinia (to the west), the Italian Peninsula (regions of Tuscany, Lazio, Campania, Basilicata, and Calabria) to the north and east, and the island of Sicily (to the south). The Tyrrhenian Sea also includes a number of smaller islands like Capri, Elba, Ischia, and Ustica. The maximum depth of the sea is . The Tyrrhenian Sea is situated near where the African and Eurasian Plates meet; therefore mountain chains and active volcanoes such as Mount Marsili are found in its depths. The eight Aeolian Islands and Ustica are located in the southern part of the sea, north of Sicily. Extent The International Hydrographic Organization define ...

Montecristo
Montecristo, also Monte Cristo (, ) and formerly Oglasa ( grc, Ὠγλάσσα, Ōglássa), is an island in the Tyrrhenian Sea and part of the Tuscan Archipelago. Administratively it belongs to the municipality of Portoferraio in the province of Livorno, Italy. The island has an area of , is approximately wide at its widest point, and is long; the coasts are steep, and extend for . The island is a state nature reserve and forms part of the Tuscan Archipelago National Park. Much of the island's fame is derived from the fact that it provides the title of 1844 novel ''The Count of Monte Cristo'', by Alexandre Dumas, and is one of the novel's settings. History The history of the island begins with the Iron Age. The Etruscans exploited the forests of oak needed to fuel the bloomeries of the mainland where the iron ore of Elba's mines was melted. The Greeks gave Montecristo its oldest known name, ''Oglasa'' or ''Ocrasia'', after the yellowish colour of the rocks. The Romans, how ...

Pianosa
Pianosa () is an island in the Tuscan Archipelago in the Tyrrhenian Sea, Italy. It is about in area, with a coastal perimeter of . Geography In Roman times the island was named ''Planasia'' (plain) because of its flatness – its highest point stands at above sea level. It is a triangular-shaped land mass south west of Elba, and is a frazione of the municipality of Campo nell'Elba. Pianosa is the fifth biggest island of the Tuscan Archipelago and the only one to be formed out of sedimentary rock of the Neogene and Quaternary; such fossils as echinoderms, mollusca and bryozoa of the Pliocene are frequently found. Flora The vegetation consists mainly of Mediterranean species as lentisco, fennel, juniper, rosemary and ''Pinus halepensis'', which was introduced on the island in the 1900s. Fauna The animals living on the island are largely small mammals, such as hedgehog and hare, introduced in the 1800s, as well as the pheasant and the red-legged partridge; the magpie and t ...

Solar Power
Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine. Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar electricity has fallen, grid-connected solar PV systems have grown more or less exponentially. Millions of installations and gigawatt-scale photovoltaic power stations continue to be built, with half of new generation capacity being solar in 2021. ...

Focal Plane
In Gaussian optics, the cardinal points consist of three pairs of points located on the optical axis of a rotationally symmetric, focal, optical system. These are the '' focal points'', the principal points, and the nodal points. For ''ideal'' systems, the basic imaging properties such as image size, location, and orientation are completely determined by the locations of the cardinal points; in fact only four points are necessary: the focal points and either the principal or nodal points. The only ideal system that has been achieved in practice is the plane mirror, however the cardinal points are widely used to ''approximate'' the behavior of real optical systems. Cardinal points provide a way to analytically simplify a system with many components, allowing the imaging characteristics of the system to be approximately determined with simple calculations. Explanation The cardinal points lie on the optical axis of the optical system. Each point is defined by the effect the opti ...

Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Light Characteristic
A light characteristic is all of the properties that make a particular navigational light identifiable. Graphical and textual descriptions of navigational light sequences and colours are displayed on nautical charts and in Light Lists with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. Different lights use different colours, frequencies and light patterns, so mariners can identify which light they are seeing. Abbreviations While light characteristics can be described in prose, e.g. "Flashing white every three seconds", lists of lights and navigation chart annotations use abbreviations. The abbreviation notation is slightly different from one light list to another, with dots added or removed, but it usually follows a pattern similar to the following (see the chart to the right for examples). * An abbreviation of the type of light, e.g. "Fl." for flashing, "F." for fixed. * The color of the light, e.g. "W" for white, "G" for green, "R" for red, ...
