Given the question: Information: - Earth, otherwise known as the world, is the third planet from the Sun and the only object in the Universe known to harbor life. It is the densest planet in the Solar System and the largest of the four terrestrial planets. - Kuwait ('), officially the State of Kuwait ('), is a country in Western Asia. Situated in the northern edge of Eastern Arabia at the tip of the Persian Gulf, it shares borders with Iraq and Saudi Arabia. , Kuwait has a population of 4.2 million people; 1.3 million are Kuwaitis and 2.9 million are expatriates. Expatriates account for 70% of the population. - The araB gene promoter is a bacterial promoter, activated by e L-arabinose binding. - Iran (, also , ; ' ), also known as Persia, officially the Islamic Republic of Iran (' ), is a sovereign state in Western Asia. It is bordered to the northwest by Armenia, the "de facto" Nagorno-Karabakh Republic, and Azerbaijan; to the north by the Caspian Sea; to the northeast by Turkmenistan; to the east by Afghanistan and Pakistan; to the south by the Persian Gulf and the Gulf of Oman; and to the west by Turkey and Iraq. Comprising a land area of , it is the second-largest country in the Middle East and the 18th-largest in the world. With 82.8 million inhabitants, Iran is the world's 17th-most-populous country. It is the only country with both a Caspian Sea and an Indian Ocean coastline. The country's central location in Eurasia and Western Asia, and its proximity to the Strait of Hormuz, make it of great geostrategic importance. Tehran is the country's capital and largest city, as well as its leading economic center. - Baghdad is the capital of the Republic of Iraq. The population of Baghdad, , is approximately 7.216.040 making it the largest city in Iraq, the second largest city in the Arab world (after Cairo, Egypt), and the second largest city in Western Asia (after Tehran, Iran). - The world is the planet Earth and all life upon it, including human civilization. In a philosophical context, the world is the whole of the physical Universe, or an ontological world. In a theological context, the "world" is the material or the profane sphere, as opposed to the celestial, spiritual, transcendent or sacred. The "end of the world" refers to scenarios of the final end of human history, often in religious contexts. - Metaphysics is a branch of philosophy investigating the fundamental nature of being and the world that encompasses it. Metaphysics attempts to answer two basic questions: - Shatt al-Arab ( "River of the Arabs") or Arvand Rud ("Swift River") is a river in Southwest Asia of some 200km (120mi) in length, formed by the confluence of the Euphrates and the Tigris in the town of al-Qurnah in the Basra Governorate of southern Iraq. The southern end of the river constitutes the border between Iraq and Iran down to the mouth of the river as it discharges into the Persian Gulf. It varies in width from about at Basra to at its mouth. It is thought that the waterway formed relatively recently in geologic time, with the Tigris and Euphrates originally emptying into the Persian Gulf via a channel further to the west. - Abu Ysuf Yaqb ibn Isq a - abb al - Kind ( Arabic : , Latin : Alkindus ) ( c. 801 -- 873 AD ) , known as '' the Philosopher of the Arabs '' , was a Muslim Arab philosopher , polymath , mathematician , physician and musician . Al - Kindi was the first of the Muslim peripatetic philosophers , and is unanimously hailed as the '' father of Islamic or Arabic philosophy '' for his synthesis , adaptation and promotion of Greek and Hellenistic philosophy in the Muslim world . Al - Kindi was a descendant of the Kinda tribe . He was born in Basra and educated in Baghdad . Al - Kindi became a prominent figure in the House of Wisdom , and a number of Abbasid Caliphs appointed him to oversee the translation of Greek scientific and philosophical texts into the Arabic language . This contact with '' the philosophy of the ancients '' ( as Greek philosophy was often referred to by Muslim scholars ) had a profound effect on his intellectual development , and led him to write hundreds of original treatises of his own on a range of subjects ranging from metaphysics , ethics , logic and psychology , to medicine , pharmacology , mathematics , astronomy , astrology and optics , and further afield to more practical topics like perfumes , swords , jewels , glass , dyes , zoology , tides , mirrors , meteorology and earthquakes . In the field of mathematics , al - Kindi played an important role in introducing Indian numerals to the Islamic and Christian world . He was a pioneer in cryptanalysis and devised several new methods of breaking ciphers . Using his mathematical and medical expertise , he was able to develop a scale that would allow doctors to quantify the potency of their medication . The central theme underpinning al - Kindi 's philosophical writings is the compatibility between philosophy and other '' orthodox '' Islamic sciences , particularly theology . And many of his works deal with subjects that theology had an immediate interest in . These include the nature of God , the soul and prophetic knowledge . But... - Basra, also al-Barah, is an Iraqi city located on the Shatt al-Arab between Kuwait and Iran. It had an estimated population of 1.5 million in 2012. Basra is also Iraq's main port, although it does not have deep water access, which is handled at the port of Umm Qasr. - Egypt (; ', , "Kimi"), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and southwest corner of Asia by a land bridge formed by the Sinai Peninsula. Egypt is a Mediterranean country bordered by the Gaza Strip and Israel to the northeast, the Gulf of Aqaba to the east, the Red Sea to the east and south, Sudan to the south, and Libya to the west. Across the Gulf of Aqaba lies Jordan, and across from the Sinai Peninsula lies Saudi Arabia, although Jordan and Saudi Arabia do not share a land border with Egypt. It is the world's only contiguous Afrasian nation. - Cairo (; ', ') is the capital and largest city of Egypt. The city's metropolitan area is the largest in the Middle East and the Arab world, and 15th-largest in the world, and is associated with ancient Egypt, as the famous Giza pyramid complex and the ancient city of Memphis are located in its geographical area. Located near the Nile Delta, modern Cairo was founded in 969CE by Jawhar al-Siqilli ("the Sicilian") of the Fatimid dynasty, but the land composing the present-day city was the site of ancient national capitals whose remnants remain visible in parts of Old Cairo. Cairo has long been a center of the region's political and cultural life, and is nicknamed "the city of a thousand minarets" for its preponderance of Islamic architecture. - Harun al-Rashid (, "Hrn Ar-Rasd"; in English: Aaron the Just, 17 March 763 or February 766 24 March 809 (148-193 Hijri) was the fifth Abbasid Caliph. His birth date is debated, with various sources giving dates from 763 to 766. His surname translates to "the Just", "the Upright", or "the Rightly-Guided"; fully translated, his name means "Aaron the Just". Al-Rashid ruled from 786 to 809, during the peak of the Islamic Golden Age. His time was marked by scientific, cultural, and religious prosperity. Islamic art and music also flourished significantly during his reign. He established the legendary library Bayt al-Hikma ("House of Wisdom") in Baghdad in present-day Iraq, and during his rule Baghdad began to flourish as a center of knowledge, culture and trade. During his rule, the family of Barmakids, which played a deciding role in establishing the Abbasid Caliphate, declined gradually. In 796, he moved his court and government to Ar-Raqqah in present-day Syria. - Humanities are academic disciplines that study aspects of human culture. In the Middle Ages, the term contrasted with divinity and referred to what is now called classics, the main area of secular study in universities at the time. Today, the humanities are more frequently contrasted with natural and sometimes social sciences as well as professional training. - Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets; while the phenomena include supernovae explosions, gamma ray bursts, and cosmic microwave background radiation. More generally, all astronomical phenomena that originate outside Earth's atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole. - Ab Jafar Abdullh al-Ma'mn ibn Hrn al-Rashd (September 786 9 August 833) was the seventh Abbasid caliph, who reigned from 813 until his death in 833. He succeeded his brother al-Amin after a civil war, and was also known for his role in the Mu'tazilism controversy, and the resumption of large-scale warfare with the Byzantine Empire. - Social science is a major category of academic disciplines, concerned with society and the relationships among individuals within a society. It in turn has many branches, each of which is considered a "social science". The main social sciences include economics, political science, human geography, demography, and sociology. In a wider sense, social science also includes some fields in the humanities such as anthropology, archaeology, jurisprudence, history, and linguistics. The term is also sometimes used to refer specifically to the field of sociology, the original 'science of society', established in the 19th century. A more detailed list of sub-disciplines within the social sciences can be found at Outline of social science. - Mesopotamia ("[land] between rivers"; from Ancient Armenian (Mijagetq); "bild ar-rfidayn" "miyn rodn"; "Beth Nahrain" "land of rivers") is a name for the area of the TigrisEuphrates river system, in modern days roughly corresponding to most of Iraq plus Kuwait, the eastern parts of Syria, Southeastern Turkey, and regions along the Turkish-Syrian and IranIraq borders. - The Arab world ('; formally: '), also known as the Arab nation (""), consists of the 22 Arabic-speaking countries of the Arab League. These Arab states occupy an area stretching from the Atlantic Ocean in the west to the Arabian Sea in the east, and from the Mediterranean Sea in the north to the Horn of Africa and the Indian Ocean in the southeast. The contemporary Arab world has a combined population of around 422 million people, over half of whom are under 25 years of age. - A star is a luminous sphere of plasma held together by its own gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye from Earth during the night, appearing as a multitude of fixed luminous points in the sky due to their immense distance from Earth. Historically, the most prominent stars were grouped into constellations and asterisms, the brightest of which gained proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. However, most of the stars in the Universe, including all stars outside our galaxy, the Milky Way, are invisible to the naked eye from Earth. Indeed, most are invisible from Earth even through the most powerful telescopes. - Medicine (British English ; American English ) is the science and practice of the diagnosis, treatment, and prevention of disease. The word "medicine" is derived from Latin "medicus", meaning "a physician". Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others. - A comet is an icy small Solar System body that, when passing close to the Sun, warms and begins to evolve gasses, a process called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet. Comet nuclei range from a few hundred metres to tens of kilometres across and are composed of loose collections of ice, dust, and small rocky particles. The coma may be up to 15 times the Earth's diameter, while the tail may stretch one astronomical unit. If sufficiently bright, a comet may be seen from the Earth without the aid of a telescope and may subtend an arc of 30 (60 Moons) across the sky. Comets have been observed and recorded since ancient times by many cultures. - Tehran ( "Tehrn") is the capital of Iran and Tehran Province. With a population of around 9 million in the city and 16 million in the wider metropolitan area, Tehran is the most populous city of Iran, the 2nd-most populous city in Western Asia and the 3rd-largest metropolitan area in the Middle East. It is ranked 29th in the world by the population of its metropolitan area. - Astrology is the study of the movements and relative positions of celestial objects as a means for divining information about human affairs and terrestrial events. Astrology has been dated to at least the 2nd millennium BCE, and has its roots in calendrical systems used to predict seasonal shifts and to interpret celestial cycles as signs of divine communications. Many cultures have attached importance to astronomical events, and some such as the Indians, Chinese, and Maya developed elaborate systems for predicting terrestrial events from celestial observations. Western astrology, one of the oldest astrological systems still in use, can trace its roots to 19th-17th century BCE Mesopotamia, from which it spread to Ancient Greece, Rome, the Arab world and eventually Central and Western Europe. Contemporary Western astrology is often associated with systems of horoscopes that purport to explain aspects of a person's personality and predict significant events in their lives based on the positions of celestial objects; the majority of professional astrologers rely on such systems. - Arabic (' or ' ) is a Central Semitic language that was first spoken in Iron Age northwestern Arabia and is now the "lingua franca" of the Arab world. Arabic also is a liturgical language of 1.7 billion Muslims. It is one of six official languages of the United Nations. It is named after the Arabs, a term initially used to describe peoples living from Mesopotamia in the east to the Anti-Lebanon mountains in the west, and from northwestern Arabia to the Sinai in the south. - Iraq (, or ; '; '), officially known as the Republic of Iraq ('; ') is a country in Western Asia, bordered by Turkey to the north, Iran to the east, Kuwait to the southeast, Saudi Arabia to the south, Jordan to the southwest, and Syria to the west. The capital, and largest city, is Baghdad. The main ethnic groups are Arabs and Kurds; others include Assyrians, Turkmen, Shabakis, Yazidis, Armenians, Mandeans, Circassians, and Kawliya. Around 95% of the country's 36 million citizens are Muslims, with Christianity, Yarsan, Yezidism, and Mandeanism also present. The official languages of Iraq are Arabic and Kurdish. - Physical cosmology is the study of the largest-scale structures and dynamics of the Universe and is concerned with fundamental questions about its origin, structure, evolution, and ultimate fate. Cosmology as a science originated with the Copernican principle, which implies that celestial bodies obey identical physical laws to those on Earth, and Newtonian mechanics, which first allowed us to understand those physical laws. Physical cosmology, as it is now understood, began with the development in 1915 of Albert Einstein's general theory of relativity, followed by major observational discoveries in the 1920s: first, Edwin Hubble discovered that the universe contains a huge number of external galaxies beyond our own Milky Way; then, work by Vesto Slipher and others showed that the universe is expanding. These advances made it possible to speculate about the origin of the universe, and allowed the establishment of the Big Bang Theory, by Georges Lemaitre, as the leading cosmological model. A few researchers still advocate a handful of alternative cosmologies; however, most cosmologists agree that the Big Bang theory explains the observations better. - Meteorology is the interdisciplinary scientific study of the atmosphere. The study of meteorology dates back millennia, though significant progress in meteorology did not occur until the 18th century. The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data. It wasn't until after the elucidation of the laws of physics and, more particularly, the development of the computer, allowing for the automated solution of a great many equations that model the weather, in the latter half of the 20th century that significant breakthroughs in weather forecasting were achieved. - Debt, AIDS, Trade, Africa (DATA) was a multinational non-government organization founded in January 2002 in London by U2's Bono along with Bobby Shriver and activists from the Jubilee 2000 Drop the Debt campaign. - Ancient Greece was a civilization belonging to a period of Greek history from the Greek Dark Ages of the 12th-9th centuries BC to the end of antiquity (AD). Immediately following this period was the beginning of the Early Middle Ages and the Byzantine era. Roughly three centuries after the Late Bronze Age collapse of Mycenaean Greece, Greek urban poleis began to form in the 8th century BC, ushering in the period of Archaic Greece and colonization of the Mediterranean Basin. This was followed by the period of Classical Greece, an era that began with the Greco-Persian Wars, lasting from the 5th to 4th centuries BC. Due to the conquests by Alexander the Great of Macedonia, Hellenistic civilization flourished from Central Asia to the western end of the Mediterranean Sea. The Hellenistic period came to an end with the conquests and annexations of the eastern Mediterranean world by the Roman Republic, which established the Roman province of Macedonia in Roman Greece, and later the province of Achaea during the Roman Empire. - Psychology is the study of behavior and mind, embracing all aspects of conscious and unconscious experience as well as thought. It is an academic discipline and a social science which seeks to understand individuals and groups by establishing general principles and researching specific cases. In this field, a professional or researcher is called a psychologist and can be classified as a social, behavioral, or cognitive scientist. Psychologists attempt to understand the role of mental functions in individual and social behavior, while also exploring the physiological and biological processes that underlie cognitive functions and behaviors. Psychologists explore behavior and mental processes, including perception, cognition, attention, emotion (affect), intelligence, phenomenology, motivation (conation), brain functioning, and personality. This extends to interaction between people, such as interpersonal relationships, including psychological resilience, family resilience, and other areas. Psychologists of diverse orientations also consider the unconscious mind. Psychologists employ empirical methods to infer causal and correlational relationships between psychosocial variables. In addition, or in opposition, to employing empirical and deductive methods, someespecially clinical and counseling psychologistsat times rely upon symbolic interpretation and other inductive techniques. Psychology has been described as a "hub science", with psychological findings linking to research and perspectives from the social sciences, natural sciences, medicine, humanities, and philosophy. While psychological knowledge is often applied to the assessment and treatment of mental health problems, it is also directed towards understanding and solving problems in several spheres of human activity. By many accounts psychology ultimately aims to benefit society. The majority of psychologists are involved in some kind of therapeutic role, practicing in clinical, counseling, or school settings. Many do scientific research on a wide range... - Western Asia, West Asia, Southwestern Asia or Southwest Asia is the westernmost subregion of Asia. The concept is in limited use, as it significantly overlaps with the Middle East (or Near East), the main difference being the exclusion of Egypt (which would be counted as part of North Africa). The term is sometimes used for the purposes of grouping countries in statistics. - The House of Wisdom ("Bayt al-Hikma") was a major intellectual center during the Islamic Golden Age. The House of Wisdom was founded by Caliph Harun al-Rashid (reigned 786809) and culminated in prominence under his son al-Ma'mun (reigned 813833) who is credited with its formal institution. Al-Ma'mun is also credited with bringing many well-known scholars to share information, ideas, and culture in the House of Wisdom. Based in Baghdad from the 9th to 13th centuries, beside Muslim scholars, people of Jewish or Christian background were allowed to study here. Besides translating books into Arabic and preserving them, scholars associated with the House of Wisdom also made many remarkable original contributions to diverse fields. - Umm Qasr (also transliterated as "Um-qasir", "Um-qasser"), is a port city in southern Iraq. It stands on the canalised Khawr az-Zubayr, part of the Khawr Abd Allah estuary which leads to the Persian Gulf. It is separated from the border of Kuwait by a small inlet. A bridge across the waterway linked the port with Kuwait prior to the 1991 Persian Gulf War.
