Life is a characteristic of organisms that exhibit certain biological processes such as chemical reactions or other events that results in a transformation. Living organisms are capable of growth and reproduction, some can communicate and many can adapt to their environment through changes originating internally. A physical characteristic of life is that it feeds on negative entropy. In more detail, according to physicists such as John Bernal, Erwin Schrödinger, Eugene Wigner, and John Avery, life is a member of the class of phenomena which are open or continuous systems able to decrease their internal entropy at the expense of substances or free energy taken in from the environment and subsequently rejected in a degraded form

Melvin Schwartz
Melvin Schwartz (November 2, 1932August 28, 2006) was an American physicist. He shared the 1988 Nobel Prize in Physics with Leon M. Lederman and Jack Steinberger for their development of the neutrino beam method and their demonstration of the doublet structure of the leptons through the discovery of the muon neutrino.
He grew up in New York City in the Great Depression and went to the Bronx High School of Science. His interest in physics began there at the age of 12.
He earned his B.A. (1953) and Ph.D. (1958) at Columbia University, where Nobel laureate I. I. Rabi was the head of the physics department. Schwartz became an assistant professor at Columbia in 1958. He was promoted to associate professor in 1960 and full professor in 1963. Tsung-Dao Lee, a Columbia colleague who had recently won the Nobel prize at age 30, inspired the experiment for which Schwartz received his Nobel. Schwartz and his colleagues performed the experiments which led to their Nobel Prize in the early 1960s, when all three were on the Columbia faculty. The experiment was carried out at the nearby Brookhaven National Laboratory.
In 1966, after 17 years at Columbia, he moved west to Stanford University, where SLAC, a new accelerator, was just being completed. There, he was involved in research investigating the charge asymmetry in the decay of long-lived neutral kaons and another project which produced and detected relativistic hydrogen-like atoms made up of a pion and a muon.
In the 1970s he founded and became president of Digital Pathways. In 1991, he became Associate Director of High Energy and Nuclear Physics at Brookhaven National Laboratory. At the same time, he rejoined the Columbia faculty as Professor of Physics. He became I. I. Rabi Professor of Physics in 1994 and retired as Rabi Professor Emeritus in 2000. He spent his retirement years in Ketchum, Idaho, and died August 28, 2006 at a Twin Falls, Idaho, nursing home after struggling with Parkinson's disease and hepatitis C.

Maximilian I of Habsburg (March 22, 1459January 12, 1519) was Holy Roman Emperor from 1508 until his death. He expanded the influence of the House of Habsburg through both war and marriage. He is often referred to as "The Last Knight".

Life and reign in the Habsburg hereditary lands
Maximilian governed his first wife's vast inheritance in the Low Countries, and he prosecuted a war over them with Louis XI, King of France on her behalf. Louis died in 1483 and his successor, Charles VIII of France, was a minor whose regent, Anne of France, ended France's bellicosity for a time. Maximilian continued to govern Mary's remaining inheritance in the name of their young son, Philip the Handsome. After the regency ended, Maximilian and Charles VIII exchanged these two territories for Burgundy and Picardy in the Treaty of Senlis (1493). Thus ultimately much of the Netherlands became and remained a Habsburg possession.

Reign in Burgundy and The Netherlands
Elected King of the Romans in 1486 at the initiative of his father, he also stood at the head of the Holy Roman Empire upon his father's death in 1493. The following year, after he married a daughter of the Duke of Milan (16 March 1494), Maximilian sought to expand his power in parts of Italy, where he had tried to re-establish the lost Habsburg dominance.
Maximilian is possibly best known for leading the 1495 Reichstag at Worms which concluded on the Reichsreform (Imperial Reform), reshaping much of the constitution of the Holy Roman Empire. In the 1499 Treaty of Basel, Maximilian was forced to acknowledge the de-facto independence of the Swiss confederacy from the Empire as a result of the Battle of Dornach.
In 1508, Maximilian, with the assent of Pope Julius II, took the title of Elected Roman Emperor (Erwählter Römischer Kaiser), and thus ended the century-old custom that the Holy Roman Emperor had to be crowned by the pope.

Tu felix Austria nube
Maximilian died in Wels, Upper Austria, and was succeeded as Emperor by his grandson Charles V, his son Philip the Handsome having died in 1506. Although he is buried in the Castle Chapel at Wiener Neustadt, a cenotaph tomb for Maximilian is located in the Innsbruck Hofkirche[1].
Maximilian was a keen supporter of the arts and sciences, and he surrounded himself with scholars such as Joachim Vadian and Andreas Stoberl (Stiborius), promoting them to important court posts. His reign saw the first flourishing of the Renaissance in Germany.
Maximilian had appointed his daughter Margarete of Austria as both Regent of the Netherlands and the guardian and educator of his grandsons Charles and Ferdinand (their father, Philip, having predeceased Maximilian), and she fulfilled this task well. Through wars and marriages he extended the Habsburg influence in every direction: to the Netherlands, Spain, Bohemia, Hungary, Poland, and Italy. This influence would last for centuries and shape much of European history.

Death and legacy


Mary of Burgundy (14571482) — married in Ghent on August 18, 1477
Anna of Brittany (14771514) — married by proxy in Rennes on December 18, 1490

Twins is a Hong Kong-based female Cantopop duo created in the summer of 2001 by Albert Yeung's Emperor Entertainment Group (EEG). Twins is made up of two young ex-models, Charlene Choi Cheuk-Yin (蔡卓妍) and Gillian Chung Yan-Tung (鍾欣桐), who by birth is originally Chung Ka-Lai.

See also: Twins discography
Like most other new singers, Twins made a great deal of effort to boost their popularity. During their first two years, they released 3 EPs and 3 albums, all of which sold very well. Most of their songs stayed at the top of many different musical charts for several weeks. Their achievements helped highlight and cement their popularity amongst other new singers. Twins had their first concert in 2002 and three more in 2003, one of which was held in Guangzhou. Between 2001 and 2003, they received a total of 48 musical awards. This was a remarkable feat for the relatively new group at the time, and it showed that their effort had been highly appreciated. In 2003, they received the largest number of awards in the annual prize presentations from the four major Hong Kong media organizations, which are RTHK, MetroRadio and TVB.

Singing career as a group
When Twins started their singing careers, there were very few musical groups in Hong Kong. However, after Twins' success, other music producers realized there was a huge market for group singers. As a result, more singing groups were formed.

Twins' effect
Twins have been subjected to a wide range of criticism concerning poor singing skills, unclear Mandarin pronunciation, and lack of a reckoning status as singers (since they showed that they have been distracted from their singing career), although most of the criticisms are unverified. Nevertheless, Twins have entered the Mandarin market successfully and their popularity keeps increasing in the Chinese music industry. Twins spoke Mandarin well when they became guest stars in Mainland China and Taiwan TV programs. Many TV hosts praised the singing, dancing, and acting skills, and attractiveness of Twins. In particular, Charlene has attracted many directors and movie investors, thus having a non-stop movie schedule for 2007. Gillian also participated in many Chinese drama series in 2006-2007. Twins state that they are currently trying hard to improve in all aspects of their performance (singing, dancing, acting), and have recently started to take singing lessons with popular entertainment voice coach Christine Samson. Twins will be releasing their third Mandarin album in late 2007.

Appraisal and criticism
The Hong Kong musical industry has shown, many pop group bands break-up after they acquire a considerable level of popularity. The Twins are not immune to this and there have been rumors that Twins is also facing the same fate. It has been suggested by EEG that their concerts due for early 2006 may be their last. However these rumours have been around before and have proved unfounded and purely for entertainment purposes in generating gossip for tabloids.
At the 2006 Hong Kong Entertainment Awards ceremony Choi tearfully acknowledged that there have been criticisms of the Twins' singing abilities and that she hoped that they could better improve in the coming year.
Twins overcame rumours of splitting up when they attended the May 2006 MTV Asia Awards in Thailand together. They were nominated for and won the Hong Kong Most Popular Singer Award. Twins garnered many more votes than Andy Lau, who was predicted to take home this award. This is arguably the most important award for their profile.
(February 2007) They have also recently celebrated their sixth year together in the Hong Kong music industry and with this the release of a special sixth anniversary new+best selection CD/DVD. Most rumours of a split have ceased and they have reaffirmed to their fans they will celebrate in another six years time.
(September 2007) To celebrate their sixth anniversary since entertaining the entertainment circle, Twins will embark on a multi-city North American concert tour, with special guests Sun Boy'Z. They will perform live on September 15,2007 at the Cow Palace in San Francisco.[1] Other stops on their tour will include Toronto, Los Angeles, and Atlantic City. It is their first time performing on a major tour across several North American cities.

Twins' fate in the coming future
Apart from their singing careers, Twins have also been involved in a number of advertisements, television series and films. Within their first three years, they had appeared in 18 advertisements, a television series, and 16 films, being cast as main characters in 6 of these.
The Twins have also been selected to promote several social campaigns in Hong Kong, such as summer activities for the Hong Kong Home Affairs Bureau in July 2003.

H.261 is a 1990 ITU-T video coding standard originally designed for transmission over ISDN lines on which data rates are multiples of 64 kbit/s. It is one member of the H.26x family of video coding standards in the domain of the ITU-T Video Coding Experts Group (VCEG). The coding algorithm was designed to be able to operate at video bit rates between 40 kbit/s and 2 Mbit/s. The standard supports two video frame sizes: CIF (352x288 luma with 176x144 chroma) and QCIF (176x144 with 88x72 chroma) using a 4:2:0 sampling scheme. It also has a backward-compatible trick for sending still picture graphics with 704x576 luma resolution and 352x288 chroma resolution (which was added in a later revision in 1993).

This article is about the city in Spain; for other uses, see Cadiz (disambiguation).
Cádiz is a city and port in southwestern Spain. It is the capital of the province of the same name, a province which is one of the eight comprising the autonomous community of Andalusia.
Cádiz, the oldest continuously-inhabited city in western Europe, has been a principal home port of the Spanish Navy since the accession of the Spanish Bourbons in the 18th century. It is also the site of the University of Cádiz.
Its peculiar location at the end of a narrow "peninsula" protruding into the Bay of Cádiz lends added charm to this ancient city. In actuality, Cádiz is on an island which is separated from the mainland by a larger island, the Isla de Léon; thus, to reach the mainland from Cádiz, it is necessary to cross a narrow channel to the low-lying Isla de Léon, before crossing another narrow channel to the mainland. This geographical circumstance has played, time and again, a significant part in the city's history, commerce, and culture. Isolated behind its high thick medieval walls on its improbable site in the middle of the bay, Cádiz, on approach from the sea, presents a dramatic and aesthetically appealing view.
Despite its unique site, Cadiz is, in most respects, a typically Andalusian city with a wealth of attractive vistas and well-preserved historical landmarks. The older part of Cádiz, within the remnants of the city walls, is commonly referred to as the Old City (in Spanish, Casco Antiguo). It is characterized by the antiquity of its various quarters (barrios), among them El Populo, La Viña, and Santa Maria, which present a marked contrast to the newer areas of town. While the Old City's street plan consists largely of narrow winding alleys connecting large plazas, newer areas of Cádiz typically have wide avenues and more modern buildings. In addition, the city is dotted by numerous parks where exotic plants, including giant trees supposedly brought to Spain by Columbus, flourish.

Etymology of the city's name
According to the 2006 census, the population of Cádiz proper was 130,561, and the population of the entire metropolitan area was estimated to be 629,054. Cádiz is the seventeenth largest Spanish city. However, in recent years, the city has been steadily losing population; it is the only municipality of the Bay of Cádiz (the comarca composed of Cádiz, Chiclana, El Puerto de Santa María, Puerto Real, and San Fernando), whose population has diminished. Between 1995 and 2006, it lost more than 14,000 inhabitants, a decrease of 9%.
Among the causes of this loss of population is the peculiar geography of Cádiz; the city lies on a narrow spit of land hemmed-in by the sea. Consequently, there is a pronounced shortage of buildable land. The city has very little vacant land, and a high proportion of its housing stock is relatively low in density. (That is to say, many buildings are only two or three stories tall, and they are only able to house a relatively small number of people within their "footprint".) The older quarters of Cádiz are full of buildings that, because of their age and historical significance, are not eligible for urban renewal. Replacement of these old buildings with high-density apartment projects would allow Cádiz to sustain a higher population.

Source: INE (Spain)
Two other physical factors tend to limit the city's population. It is impossible to increase the amount of land available for building by reclaiming land from the sea; a new national law governing coastal development thwarts this solution. Also, because Cádiz is built on a sandspit, it is a costly proposition to sink foundations deep enough to support the high-rise buildings that would allow for a higher population density. As it stands, the city's skyline is not substantially different than it was in medieval times. A seventeenth-century watchtower, the Tavira tower, still commands a panoramic view of the city and the bay despite its relatively modest 45-metre height. (See below.)
Cádiz is the provincial capital with the highest rate of unemployment in Spain. This, too, tends to depress the population level. Young Gaditanos, those between 18 and 30 years of age, have been migrating, to other places in Spain (Madrid and Castellón, chiefly), as well as emigrating to other places in Europe and the Americas. The population younger than twenty years old is only 20.58% of the total, and the population older than sixty-five is 21.67%, making Cádiz one of the most aged cities in all of Spain.
Despite these trends, some are cheered by the fact that the other towns and cities surrounding the Bay of Cádiz are growing modestly, absorbing some of the population fleeing the capital. Improvements in roads and railways have allowed people to commute to Cádiz for work more easily. Increasingly, outlying communities, like Puerto Real and San Fernando, are providing bedrooms for Cádiz's workforce. In recent years, Cádiz has become more of a place to work than a place to live.

Population and demographic trends
The city was originally founded as Gadir (Phoenician גדר "walled city") by the Phoenicians, who used it in their trade with Tartessos, a city-state believed by archæologists to be somewhere near the mouth of the Guadalquivir River, about thirty kilometres northwest of Cádiz. (Its exact location has never been firmly established.)
Cádiz is the most ancient city still standing in western Europe It is a connection that continutes to this day.
Cádiz was also the seat of the liberal Cortes (parliament) that fought against Joseph Napoleon Bonaparte (also known as Joseph I of Spain) in the Peninsular War and where the Spanish Constitution of 1812 was proclaimed. The citizens again revolted in 1820 to secure a renewal of this constitution; the revolution spread across Spain, leading to the imprisonment of King Ferdinand VII in the city of Cádiz. French forces secured the release of Ferdinand in 1823 and suppressed liberalism. In 1868, Cádiz was once again the seat of a revolution, resulting in the eventual abdication and exile of Queen Isabella II. (The same Cádiz Cortes decided to reinstate the monarchy under King Amadeo I just two years later.)
In recent years, the city has undergone much reconstruction. Many monuments, cathedrals, and landmarks have been cleaned and restored, adding to the considerable charm of this ancient city.


Main article: Diocese of Cadiz y CeutaCadiz Diocese
Among the many landmarks of historical and scenic interest in Cadiz, a few stand out. The city can boast of an unusual cathedral of various architectural styles, a magnificent theatre, an attractive old municipal building, an eighteenth-century watchtower, a vestige of the ancient city wall, an ancient Roman theatre, and electrical pylons of an eye-catching modern design carrying cables across the Bay of Cadiz.

Major landmarks

Landmark Buildings
One of Cádiz's most famous landmarks is its cathedral. It sits on the site of an older cathedral, completed in 1260, which burned down in 1596. The reconstruction, which was not started until 1776, was supervised by the architect Vicente Acero, who had also built the Granada Cathedral. Acero left the project and was succeeded by several other architects. As a result, this largely baroque-style cathedral was built over a period of 116 years, and, due to this drawn-out period of construction, the cathedral underwent several major changes to its original design. Though the cathedral was originally intended to be a baroque edifice, it contains rococo elements, and was finally completed in the neoclassical style. Its chapels have many paintings and relics from the old cathedral and monasteries from throughout Spain.

The Gran Teatro Falla (Falla Grand Theatre)
In the 18th century, Cádiz had more than 160 towers from which local merchants could look out to sea for arriving merchant ships. These towers often formed part of the merchants' houses. The Torre Tavira, named for its original owner, stands as the tallest remaining watchtower. It has a cámara oscura, a room that uses the principal of the pinhole camera (and a specially-prepared convex lens) to project panoramic views of the Old City onto its interior walls. (Also see the article titled Widow's walk.)

The Tavira tower
The Casa del Almirante is a palatial house, adjacent to the Plaza San Martín in the Barrio del Pópulo, which was constructed in 1690 with the proceeds of the lucrative trade with the Americas. It was built by the family of the admiral of the Spanish treasure fleet, the so-called Fleet of the Indies, Don Diego de Barrios. The exterior is sheathed in exquisite red and white Genoan marble, prepared in the workshops of Andreoli, and mounted by the master, García Narváez. The colonnaded portico, the grand staircase under the cupola, and the hall on the main floor are architectural features of great nobility and beauty. The shield of the Barrios family appears on the second-floor balcony.

The Admiral's House
The old town of Cadiz is one of the most densely populated urban areas in Europe, and is packed with narrow streets. The old town benefits though from five striking plazas, which are enjoyed by citizens and tourists alike. These are Plaza de Mina, Plaza San Antonio, Plaza de Candelaria, Plaza de San Juan de Dios and Plaza de España.

The Plazas

Located in the heart of the old town, Plaza de Mina, (the most beautiful of the Cadiz plazas) was developed in the first half of the nineteenth century. Previously, the land occupied by the plaza was the orchard of the convent of San Francisco. The plaza, was converted into a plaza in 1838 by the architect Torcuato Benjumeda and (later) Juan Daura, with its trees being planted in 1861. It was then redeveloped again in 1897, and has remained virtually unchanged since. It is named after General Francisco Espoz y Mina, a hero of the war of independence. Manuel de Falla y Matheu was born in Number 3 Plaza de Mina, where a plaque bears his name. The plaza also contains several statues, one of these is a bust of José Macpherson (a pioneer in the development of petrography, stratigraphy and tectonics) who was born in number 12 Plaza de Mina in 1839. The Museum of Cadiz, is to be found at number 5 Plaza de Mina, and contains many objects from Cadiz's 3000 year history as well as works by artists such as Peter Paul Rubens. The houses which face the plaza, many of which can be classified as neo-classical architecture or built in the style of Isabelline Gothic, were originally occupied by the Cadiz bourgeoisie.

Plaza de Mina

In the 19th century Plaza San Antonio was considered to Cadiz's main square. It is a beautiful square, surrounded by a number of mansions built in neo-classical architecture or Isabelline Gothic style, once occupied by the Cadiz upper classes. San Antonio church, originally built in 1669, is also situated in the plaza,

The plaza was built in the 18th century, and on 19 March 1812 the Spanish Constitution of 1812 was proclaimed here, leading to the plaza to be named Plaza de la Constitución, and then later Plaza San Antonio, after the hermit San Antonio.

Plaza San Antonio

The Plaza de Candelaria is named after the Candelaria convent, situated in the square until it was demolished in 1873, when its grounds were redeveloped as a plaza. The plaza is notable for a statue in its centre of Emilio Castelar, president of the first Spanish republic, who was born in a house facing the square. A plaque situated on another house, states that the Irish-Spanish adventurer en:Bernardo O'Higgins and former dictator of Chile also lived in the square.

Plaza de Candelaria

Construction of this plaza began in the 15th century on lands reclaimed from the sea. With the demolition of the City walls in 1906 the plaza increased in size and a statue of the Cadiz politician Segismundo Moret was unveiled. Overlooking the plaza, the Ayuntamiento is the town hall of Cádiz's Old City. The structure, constructed on the bases and location of the previous Consistorial Houses (1699), was built in two stages. The first stage began in 1799 under the direction of architect Torcuato Benjumeda in the neoclassical style. The second stage was completed in 1861 under the direction of García del Alamo, in the Isabelline Gothic (in Spanish, "Gótico Isabelino" or, simply, the "Isabelino") style. Here, in 1936, the flag of Andalusia was hoisted for the first time.

Plaza de San Juan de Dios and the Old Town Hall

The Plaza de España is a large square close to the port. It is dominated by the Monument to the Constitution of 1812, which came into being as a consequence of the demolition of a portion of the old city wall. The plaza is an extension of the old Plazuela del Carbón. The goal of this demolition was to create a grand new city square to mark the hundredth anniverary of the liberal constitution, which was proclaimed in this city in 1812, and provide a setting for a suitable memorial. The work is by the architect, Modesto Lopez Otero, and of the sculptor, Aniceto Marinas. The work began in 1912 and finished in 1929.

The lower level of the monument represents a chamber and an empty presidential armchair. The upper level has various inscriptions surmounting the chamber. On each side are bronze figures representing peace and war. In the center, a pilaster rises to symbolize, in allegorical terms, the principals expressed in the 1812 constitution. At the foot of this pilaster, there is a female figure representing Spain, and, to either side, scuptural groupings representing agriculture and citizenship.

The City Walls
Las Puertas de Tierra originated in the 16th century, although much of the original work has disappeared. Once consisting of several layers of walls, only one of these remain today. By the 20th century it was necessary to remodel the entrance to the Old City to accommodate modern traffic. Today, the two side-by-side arches cut into the wall serve as one of the primary entrances to the city.

The old city wall
The Baluarte de la Candelaria (fortress or stronghold of Candlemas) is a military fortification. Taking advantage of a natural elevation of land, it was constructed in 1672 at the initiative of the governor, Diego Caballero de Illescas. Protected by a seaward-facing wall that had previously served as a seawall, Candelaria's cannons were in a position to command the channels approaching the port of Cádiz. In more recent times, the edifice has served as a headquarters for the corps of military engineers and as the home to the army's homing pigeons, birds used to carry written messages over hostile terrain. Thoroughly renovated, it is now used as a cultural venue. There has been some discussion of using it to house a maritime museum, but, at present, it is designated for use as a permanent exposition space.

The fortress of Candelaria
In 1980, in the El Pópulo district of Cádiz, there was a fire in some old warehouses belonging to a company called Vigorito, SA, causing catastrophic damage. In the aftermath of the fire, an exciting discovery was made: the remains of an ancient Roman theatre. The fire had destroyed the warehouses revealing a layer of construction that was judged to be the foundations of some medieval buildings; the foundations of these buildings had been built, in turn, upon much more ancient stones, hand-hewn limestone of a Roman character. Systematic excavations, which still continue, have revealed a largely in-tact Roman theatre.
The theatre, constructed by order of Lucius Cornelius Balbus (minor) during the first century BCE, is the second largest Roman theatre in the world, surpassed only by the theater of Pompeii, south of Rome. Cicero, in "Epistulae ad Familiares" (Letters to his friends), wrote of its use by Balbo for personal propaganda.
According to archaeologists, this discovery confirms the greatness of the Roman city of Gades. The ancient city had a population even greater than the 80,000 people who lived in Cádiz during the sixteenth and seventeenth century, when the city dominated trans-Atlantic commerce, and it was one of the most prosperous cities of the Roman empire.

The Roman theatre
The Pylons of Cádiz are electricity pylons of unusual design, one on either side of the Bay of Cádiz, used to support huge electric-power cables. The pylons are 158 metres high and designed for two circuits. The very unconventional construction consists of a narrow frustum steel framework with one crossbar at the top of each one for the insulators.

The pylons of Cádiz
Cádiz, situated on a peninsula[3], is home to some of Spain's most beautiful beaches.
La Playa de la Caleta is the best-loved beach of Cádiz. It has always been in Carnival songs, due to its unequalled beauty and its proximity to the Barrio de la Viña. It is the beach of the Old City, situated between two castles, San Sebastian and Santa Catalina. It is around four hundred meters long and thirty meters wide at low tide. Also, the James Bond movie, Die Another Day, was filmed here. (It was supposed to be Cuba.)
La Playa de la Victoria, in the newer part of Cádiz, is the beach most visited by tourists and natives of Cádiz. It is about three kilometers long, and it has an average width of fifty meters of sand. The moderate swell and the absence of rocks allow family bathing. It is separated from the city by an avenue; on the landward side of the avenue, there are many shops and restaurants.
La Playa de Santa María del Mar or Playita de las Mujeres is a small beach in Cádiz, situated between La Playa de Victoria and La Playa de la Caleta. It features excellent views of the old district of Cádiz.
