Philadelphia, colloquially Philly, is a city in the state of Pennsylvania in the United States. It is the sixth-most-populous city in the United States and the most populous city in the state of Pennsylvania, with a 2019 estimated population of 1,584,064. It is also the second-most populous city in the Northeastern United States, behind New York City. Since 1854, the city has had the same geographic boundaries as Philadelphia County, the most-populous county in Pennsylvania and the urban core of the eighth-largest U.S. metropolitan statistical area, with over 6 million residents as of 2017. Philadelphia is also the economic and cultural center of the greater Delaware Valley along the lower Delaware and Schuylkill rivers within the Northeast megalopolis. The Delaware Valley's 2019 estimated population of 7.21 million makes it the ninth-largest combined statistical area in the United States.Philadelphia is one of the oldest municipalities in the United States. William Penn, an English Quaker, founded the city in 1682 to serve as capital of the Pennsylvania Colony. Philadelphia played an instrumental role in the American Revolution as a meeting place for the Founding Fathers of the United States, who signed the Declaration of Independence in 1776 at the Second Continental Congress, and the Constitution at the Philadelphia Convention of 1787. Several other key events occurred in Philadelphia during the Revolutionary War including the First Continental Congress, the preservation of the Liberty Bell, the Battle of Germantown, and the Siege of Fort Mifflin. Philadelphia remained the nation's largest city until being overtaken by New York City in 1790; the city was also one of the nation's capitals during the revolution, serving as temporary U.S. capital while Washington, D.C. was under construction.

A camel is an even-toed ungulate in the genus Camelus that bears distinctive fatty deposits known as "humps" on its back. Camels have long been domesticated and, as livestock, they provide food (milk and meat) and textiles (fiber and felt from hair). Camels are working animals especially suited to their desert habitat and are a vital means of transport for passengers and cargo. There are three surviving species of camel. The one-humped dromedary makes up 94% of the world's camel population, and the two-humped Bactrian camel makes up 6%. The Wild Bactrian camel is a separate species and is now critically endangered.
The word camel is also used informally in a wider sense, where the more correct term is "camelid", to include all seven species of the family Camelidae: the true camels (the above three species), along with the "New World" camelids: the llama, the alpaca, the guanaco, and the vicuña. The word itself is derived via Latin: camelus and Greek: κάμηλος (kamēlos) from Hebrew, Arabic or Phoenician: gāmāl.

The average life expectancy of a camel is 40 to 50 years. A full-grown adult dromedary camel stands 1.85 m (6 ft 1 in) at the shoulder and 2.15 m (7 ft 1 in) at the hump.

New Zealand (Māori: Aotearoa [aɔˈtɛaɾɔa]) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island (Te Ika-a-Māui) and the South Island (Te Waipounamu)—and more than 700 smaller islands, covering a total area of 268,021 square kilometres (103,500 sq mi). New Zealand is about 2,000 kilometres (1,200 mi) east of Australia across the Tasman Sea and 1,000 kilometres (600 mi) south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland.
Owing to their remoteness, the islands of New Zealand were the last large habitable lands to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer, Abel Tasman, became the first European to sight New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs signed the Treaty of Waitangi, which declared British sovereignty over the islands. In 1841, New Zealand became a colony within the British Empire, and in 1907 it became a dominion; it gained full statutory independence in 1947, and the British monarch remained the head of state.

The Grand Canyon (Hopi: Ongtupqa, Yavapai: Wi:kaʼi:la,  Navajo: Bidááʼ Haʼaztʼiʼ Tsékooh, Spanish: Gran Cañón) is a steep-sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (6,093 feet or 1,857 meters).The canyon and adjacent rim are contained within Grand Canyon National Park, the Kaibab National Forest, Grand Canyon–Parashant National Monument, the Hualapai Indian Reservation, the Havasupai Indian Reservation and the Navajo Nation. President Theodore Roosevelt was a major proponent of the preservation of the Grand Canyon area and visited it on numerous occasions to hunt and enjoy the scenery.
Nearly two billion years of Earth's geological history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted. While some aspects about the history of incision of the canyon are debated by geologists, several recent studies support the hypothesis that the Colorado River established its course through the area about 5 to 6 million years ago. Since that time, the Colorado River has driven the down-cutting of the tributaries and retreat of the cliffs, simultaneously deepening and widening the canyon.
For thousands of years, the area has been continuously inhabited by Native Americans, who built settlements within the canyon and its many caves. The Pueblo people considered the Grand Canyon a holy site, and made pilgrimages to it. The first European known to have viewed the Grand Canyon was García López de Cárdenas from Spain, who arrived in 1540.


== Geography ==

The Grand Canyon is a river valley in the Colorado Plateau that exposes uplifted Proterozoic and Paleozoic strata, and is also one of the six distinct physiographic sections of the Colorado Plateau province.

The koala or, inaccurately, koala bear  (Phascolarctos cinereus), is an arboreal herbivorous marsupial native to Australia. It is the only extant representative of the family Phascolarctidae and its closest living relatives are the wombats, which are members of the family Vombatidae. The koala is found in coastal areas of the mainland's eastern and southern regions, inhabiting Queensland, New South Wales, Victoria, and South Australia. It is easily recognisable by its stout, tailless body and large head with round, fluffy ears and large, spoon-shaped nose. The koala has a body length of 60–85 cm (24–33 in) and weighs 4–15 kg (9–33 lb). Fur colour ranges from silver grey to chocolate brown. Koalas from the northern populations are typically smaller and lighter in colour than their counterparts further south. These populations possibly are separate subspecies, but this is disputed.
Koalas typically inhabit open eucalypt woodlands, and the leaves of these trees make up most of their diet. Because this eucalypt diet has limited nutritional and caloric content, koalas are largely sedentary and sleep up to 20 hours a day.

Robinson Crusoe () is a novel by Daniel Defoe, first published on 25 April 1719. The first edition credited the work's protagonist Robinson Crusoe as its author, leading many readers to believe he was a real person and the book a travelogue of true incidents.Epistolary, confessional, and didactic in form, the book is presented as an autobiography of the title character (whose birth name is Robinson Kreutznaer) – a castaway who spends 28 years on a remote tropical desert island near the coasts of Venezuela and Trinidad, encountering cannibals, captives, and mutineers, before ultimately being rescued. The story has been thought to be based on the life of Alexander Selkirk, a Scottish castaway who lived for four years on a Pacific island called "Más a Tierra", now part of Chile, which was renamed Robinson Crusoe Island in 1966.Despite its simple narrative style, Robinson Crusoe was well received in the literary world and is often credited as marking the beginning of realistic fiction as a literary genre. It is generally seen as a contender for the first English novel. Before the end of 1719, the book had already run through four editions, and it has gone on to become one of the most widely published books in history, spawning so many imitations, not only in literature but also in film, television, and radio, that its name is used to define a genre, the Robinsonade.


== Plot summary ==

Crusoe (the family name corrupted from the German name "Kreutznaer") set sail from Kingston upon Hull on a sea voyage in August 1651, against the wishes of his parents, who wanted him to pursue a career in law. After a tumultuous journey where his ship is wrecked in a storm, his desire for the sea remains so strong that he sets out to sea again. This journey, too, ends in disaster, as the ship is taken over by Salé pirates (the Salé Rovers) and Crusoe is enslaved by a Moor. Two years later, he escapes in a boat with a boy named Xury; a captain of a Portuguese ship off the west coast of Africa rescues him. The ship is en route to Brazil.

Benjamin Franklin  (January 17, 1706 [O.S. January 6, 1705] –  April 17, 1790) was one of the Founding Fathers of the United States. A polymath, he was a leading writer, printer, political philosopher, politician, Freemason, postmaster, scientist, inventor, humorist, civic activist, statesman, and diplomat. As a scientist, he was a major figure in the American Enlightenment and the history of physics for his discoveries and theories regarding electricity. As an inventor, he is known for the lightning rod, bifocals, and the Franklin stove, among other inventions. He founded many civic organizations, including the Library Company, Philadelphia's first fire department, and the University of Pennsylvania.Franklin earned the title of "The First American" for his early and indefatigable campaigning for colonial unity, initially as an author and spokesman in London for several colonies. As the first United States ambassador to France, he exemplified the emerging American nation. Franklin was foundational in defining the American ethos as a marriage of the practical values of thrift, hard work, education, community spirit, self-governing institutions, and opposition to authoritarianism both political and religious, with the scientific and tolerant values of the Enlightenment. In the words of historian Henry Steele Commager, "In Franklin could be merged the virtues of Puritanism without its defects, the illumination of the Enlightenment without its heat." To Walter Isaacson, this makes Franklin "the most accomplished American of his age and the most influential in inventing the type of society America would become."Franklin became a successful newspaper editor and printer in Philadelphia, the leading city in the colonies, publishing the Pennsylvania Gazette at the age of 23. He became wealthy publishing this and Poor Richard's Almanack, which he authored under the pseudonym "Richard Saunders". After 1767, he was associated with the Pennsylvania Chronicle, a newspaper that was known for its revolutionary sentiments and criticisms of the policies of the British Parliament and the Crown.He pioneered and was the first president of Academy and College of Philadelphia which opened in 1751 and later became the University of Pennsylvania.

Americans are the citizens and nationals of the United States of America. 
Although citizens and nationals make up the majority of Americans, many dual citizens, expatriates and permanent residents could also legally claim American nationality. The United States is home to people of many ethnic origins. As a result, American culture and law does not equate nationality with race or ethnicity, but with bona fide citizenship and an oath of permanent allegiance.


== Overview ==

The majority of Americans or their ancestors immigrated to America or are descended from people who were brought as slaves within the past five centuries, with the exception of the Native American population and people from Hawaii, Puerto Rico, Guam, and the Philippine Islands, who became American through expansion of the country in the 19th century, additionally America expanded into American Samoa, the U.S. Virgin Islands and Northern Mariana Islands in the 20th century.Despite its multi-ethnic composition, the culture of the United States held in common by most Americans can also be referred to as mainstream American culture, a Western culture largely derived from the traditions of Northern and Western European colonists, settlers, and immigrants. It also includes influences of African-American culture. Westward expansion integrated the Creoles and Cajuns of Louisiana and the Hispanos of the Southwest and brought close contact with the culture of Mexico. Large-scale immigration in the late 19th and early 20th centuries from Southern and Eastern Europe introduced a variety of elements. Immigration from Asia, Africa, and Latin America has also had impact. A cultural melting pot, or pluralistic salad bowl, describes the way in which generations of Americans have celebrated and exchanged distinctive cultural characteristics.In addition to the United States, Americans and people of American descent can be found internationally.

Russia (Russian: Россия, Rossiya, Russian pronunciation: [rɐˈsʲijə]), or the Russian Federation, is a country spanning Eastern Europe and Northern Asia. It is the largest country in the world, covering over 17 million square kilometres (6.6×10^6 sq mi), and encompassing more than one-eighth of Earth's inhabited land area. Russia extends across eleven time zones, and has borders with sixteen sovereign nations. It has a population of 146.2 million; and is the most populous country in Europe, and the ninth-most populous country in the world. Moscow, the capital, is the largest city in Europe, while Saint Petersburg is the nation's second-largest city and cultural centre. Russians are the largest Slavic and European nation; they speak Russian, the most spoken Slavic language, and the most spoken native language in Europe.
The East Slavs emerged as a recognisable group in Europe between the 3rd and 8th centuries AD. The medieval state of Rus' arose in the 9th century. In 988, it adopted Orthodox Christianity from the Byzantine Empire, beginning the synthesis of Byzantine and Slavic cultures that defined Russian culture for the next millennium. Rus' ultimately disintegrated until it was finally reunified by the Grand Duchy of Moscow in the 15th century. By the 18th century, the nation had greatly expanded through conquest, annexation, and exploration to become the Russian Empire, the third-largest empire in history.

Marie Salomea Skłodowska Curie ( KEWR-ee; French: [kyʁi]; Polish: [kʲiˈri]), born Maria Salomea Skłodowska (Polish: [ˈmarja salɔˈmɛa skwɔˈdɔfska]; 7 November 1867 – 4 July 1934), was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. As the first of the Curie family legacy of five Nobel Prizes, she was the first woman to win a Nobel Prize, the first person and the only woman to win the Nobel Prize twice, and the only person to win the Nobel Prize in two scientific fields. She was the first woman to become a professor at the University of Paris in 1906.She was born in Warsaw, in what was then the Kingdom of Poland, part of the Russian Empire. She studied at Warsaw's clandestine Flying University and began her practical scientific training in Warsaw. In 1891, aged 24, she followed her elder sister Bronisława to study in Paris, where she earned her higher degrees and conducted her subsequent scientific work. In 1895 she married the French physicist Pierre Curie, and she shared the 1903 Nobel Prize in Physics with him and with the physicist Henri Becquerel for their pioneering work developing the theory of "radioactivity"—a term she coined. In 1906 Pierre Curie died in a Paris street accident. Marie won the 1911 Nobel Prize in Chemistry for her discovery of the elements polonium and radium, using techniques she invented for isolating radioactive isotopes.
Under her direction, the world's first studies were conducted into the treatment of neoplasms by the use of radioactive isotopes. In 1920 she founded the Curie Institute in Paris, and in 1932 the Curie Institute in Warsaw; both remain major centres of medical research.

Cucumber (Cucumis sativus) is a widely-cultivated creeping vine plant in the Cucurbitaceae gourd family that bears cucumiform fruits, which are used as vegetables. There are three main varieties of cucumber—slicing, pickling, and burpless/seedless—within which several cultivars have been created. The cucumber originates from South Asia, but now grows on most continents, as many different types of cucumber are traded on the global market. In North America, the term wild cucumber refers to plants in the genera Echinocystis and Marah, though the two are not closely related.


== Description ==
The cucumber is a creeping vine that roots in the ground and grows up trellises or other supporting frames, wrapping around supports with thin, spiraling tendrils. The plant may also root in a soilless medium, whereby it will sprawl along the ground in lieu of a supporting structure. The vine has large leaves that form a canopy over the fruits.The fruit of typical cultivars of cucumber is roughly cylindrical, but elongated with tapered ends, and may be as large as 62 centimeters (24 in) long and 10 centimeters (4 in) in diameter.Cucumber fruits consist of 95% water (see nutrition table). In botanical terms, the cucumber is classified as a pepo, a type of botanical berry with a hard outer rind and no internal divisions. However, much like tomatoes and squashes, it is often perceived, prepared, and eaten as a vegetable.

		
		
		
		
		


=== Flowering and pollination ===
A few cultivars of cucumber are parthenocarpic, the blossoms of which create seedless fruit without pollination, which degrades the eating quality of these cultivar.

Daniel Gerhard Brown (born June 22, 1964) is an American author best known for his thriller novels, including the Robert Langdon novels Angels & Demons (2000), The Da Vinci Code (2003), The Lost Symbol (2009), Inferno (2013) and Origin (2017). His novels are treasure hunts that usually take place over a period of 24 hours. They feature recurring themes of cryptography, art, and conspiracy theories. His books have been translated into 57 languages and, as of 2012, have sold over 200 million copies. Three of them, Angels & Demons, The Da Vinci Code, and Inferno, have been adapted into films.
The Robert Langdon novels are deeply engaged with Christian themes and historical fact, and have generated controversy as a result. Brown states on his website that his books are not anti-Christian and he is on a "constant spiritual journey" himself. He claims that his book The Da Vinci Code is simply "an entertaining story that promotes spiritual discussion and debate" and suggests that the book may be used "as a positive catalyst for introspection and exploration of our faith."


== Early life ==
Dan Gerhard Brown was born on June 22, 1964, in Exeter, New Hampshire. He has a younger sister, Valerie (born 1968) and brother, Gregory (born 1974). Brown attended Exeter's public schools until the ninth grade.
