Title: Han_dynasty
Context: One of the Han's greatest mathematical advancements was the world's first use of negative numbers. Negative numbers first appeared in the Nine Chapters on the Mathematical Art as black counting rods, where positive numbers were represented by red counting rods. Negative numbers are used in the Bakhshali manuscript of ancient India, but its exact date of compilation is unknown. Negative numbers were also used by the Greek mathematician Diophantus in about 275 AD, but were not widely accepted in Europe until the 16th century AD.

Title: Han_dynasty
Context: Han-era astronomers adopted a geocentric model of the universe, theorizing that it was shaped like a sphere surrounding the earth in the center. They assumed that the Sun, Moon, and planets were spherical and not disc-shaped. They also thought that the illumination of the Moon and planets was caused by sunlight, that lunar eclipses occurred when the Earth obstructed sunlight falling onto the Moon, and that a solar eclipse occurred when the Moon obstructed sunlight from reaching the Earth. Although others disagreed with his model, Wang Chong accurately described the water cycle of the evaporation of water into clouds.

Title: Han_dynasty
Context: Evidence found in Chinese literature, and archaeological evidence, show that cartography existed in China before the Han. Some of the earliest Han maps discovered were ink-penned silk maps found amongst the Mawangdui Silk Texts in a 2nd-century-BC tomb. The general Ma Yuan created the world's first known raised-relief map from rice in the 1st century AD. This date could be revised if the tomb of Qin Shi Huang is excavated and the account in the Records of the Grand Historian concerning a model map of the empire is proven to be true.

question: What textile were some of the early Han maps made from? 

answer: silk

question: In what type of building were silken maps found? 

answer: tomb

question: Which individual created the very first raised relief map? 

answer: Ma Yuan

question: What food stable was the first raised relief map created from?

Title: Han_dynasty
Context: The Han-era Chinese sailed in a variety of ships differing from those of previous eras, such as the tower ship. The junk design was developed and realized during Han. Junks featured a square-ended bow and stern, a flat-bottomed hull or carvel-shaped hull with no keel or sternpost, and solid transverse bulkheads in the place of structural ribs found in Western vessels. Moreover, Han ships were the first in the world to be steered using a rudder at the stern, in contrast to the simpler steering oar used for riverine transport, allowing them to sail on the high seas.

question: What type of boat design was first invented during the Han era? 

answer: The junk design

question: In what areas were Han ships able to be sailed in part due to the stern rudder? 

answer: high seas

question: What ship design contained a flat-bottomed hull? 

answer: Junks

question: What type of transport was the steering oar most likely to be used during? 

answer: riverine transport
Title: Han_dynasty
Context: Han-era medical physicians believed that the human body was subject to the same forces of nature that governed the greater universe, namely the cosmological cycles of yin and yang and the five phases. Each organ of the body was associated with a particular phase. Illness was viewed as a sign that qi or "vital energy" channels leading to a certain organ had been disrupted. Thus, Han-era physicians prescribed medicine that was believed to counteract this imbalance. For example, since the wood phase was believed to promote the fire phase, medicinal ingredients associated with the wood phase could be used to heal an organ associated with the fire phase. To this end, the physician Zhang Zhongjing (c. 150–c. 219 AD) prescribed regulated diets rich in certain foods that were thought to cure specific illnesses. These are now known to be nutrition disorders caused by the lack of certain vitamins consumed in one's diet. Besides dieting, Han physicians also prescribed moxibustion, acupuncture, and calisthenics as methods of maintaining one's health. When surgery was performed by the physician Hua Tuo (d. 208 AD), he used anesthesia to numb his patients' pain and prescribed a rubbing ointment that allegedly sped the process of healing surgical wounds.

answer: prescribed regulated diets

question: When did Hua Tuo die? 

answer: 208 AD
Title: Greeks
Context: Greek colonies and communities have been historically established on the shores of the Mediterranean Sea and Black Sea, but the Greek people have always been centered around the Aegean and Ionian seas, where the Greek language has been spoken since the Bronze Age. Until the early 20th century, Greeks were distributed between the Greek peninsula, the western coast of Asia Minor, the Black Sea coast, Cappadocia in central Anatolia, Egypt, the Balkans, Cyprus, and Constantinople. Many of these regions coincided to a large extent with the borders of the Byzantine Empire of the late 11th century and the Eastern Mediterranean areas of ancient Greek colonization. The cultural centers of the Greeks have included Athens, Thessalonica, Alexandria, Smyrna, and Constantinople at various periods.

Title: Greeks
Context: The evolution of Proto-Greek should be considered within the context of an early Paleo-Balkan sprachbund that makes it difficult to delineate exact boundaries between individual languages. The characteristically Greek representation of word-initial laryngeals by prothetic vowels is shared, for one, by the Armenian language, which also seems to share some other phonological and morphological peculiarities of Greek; this has led some linguists to propose a hypothetical closer relationship between Greek and Armenian, although evidence remains scant.

answer: linguists to propose a hypothetical closer relationship between Greek and Armenian, although evidence remains scant.
Title: Greeks
Context: Around 1200 BC, the Dorians, another Greek-speaking people, followed from Epirus. Traditionally, historians have believed that the Dorian invasion caused the collapse of the Mycenaean civilization, but it is likely the main attack was made by seafaring raiders (sea peoples) who sailed into the eastern Mediterranean around 1180 BC. The Dorian invasion was followed by a poorly attested period of migrations, appropriately called the Greek Dark Ages, but by 800 BC the landscape of Archaic and Classical Greece was discernible.

question: What areas were being explored by others in  by sea faring vessels and when are they believed to have arrived  ? 

answer: seafaring raiders (sea peoples) who sailed into the eastern Mediterranean around 1180 BC
Title: Greeks
Context: The Greeks of classical antiquity idealized their Mycenaean ancestors and the Mycenaean period as a glorious era of heroes, closeness of the gods and material wealth. The Homeric Epics (i.e. Iliad and Odyssey) were especially and generally accepted as part of the Greek past and it was not until the 19th century that scholars began to question Homer's historicity. As part of the Mycenaean heritage that survived, the names of the gods and goddesses of Mycenaean Greece (e.g. Zeus, Poseidon and Hades) became major figures of the Olympian Pantheon of later antiquity.

answer: Zeus, Poseidon and Hades
Title: Greeks
Context: The ethnogenesis of the Greek nation is linked to the development of Pan-Hellenism in the 8th century BC. According to some scholars, the foundational event was the Olympic Games in 776 BC, when the idea of a common Hellenism among the Greek tribes was first translated into a shared cultural experience and Hellenism was primarily a matter of common culture. The works of Homer (i.e. Iliad and Odyssey) and Hesiod (i.e. Theogony) were written in the 8th century BC, becoming the basis of the national religion, ethos, history and mythology. The Oracle of Apollo at Delphi was established in this period.

question: What famous spiritual guide and God was a devotional temple made to in the 8th century ? 

answer: Oracle of Apollo at Delphi
Title: Greeks
Context: The classical period of Greek civilization covers a time spanning from the early 5th century BC to the death of Alexander the Great, in 323 BC (some authors prefer to split this period into 'Classical', from the end of the Persian wars to the end of the Peloponnesian War, and 'Fourth Century', up to the death of Alexander). It is so named because it set the standards by which Greek civilization would be judged in later eras. The Classical period is also described as the "Golden Age" of Greek civilization, and its art, philosophy, architecture and literature would be instrumental in the formation and development of Western culture.

Title: Greeks
Context: In any case, Alexander's toppling of the Achaemenid Empire, after his victories at the battles of the Granicus, Issus and Gaugamela, and his advance as far as modern-day Pakistan and Tajikistan, provided an important outlet for Greek culture, via the creation of colonies and trade routes along the way. While the Alexandrian empire did not survive its creator's death intact, the cultural implications of the spread of Hellenism across much of the Middle East and Asia were to prove long lived as Greek became the lingua franca, a position it retained even in Roman times. Many Greeks settled in Hellenistic cities like Alexandria, Antioch and Seleucia. Two thousand years later, there are still communities in Pakistan and Afghanistan, like the Kalash, who claim to be descended from Greek settlers.

answer: there are still communities in Pakistan and Afghanistan, like the Kalash, who claim to be descended from Greek settlers.

question: Name a city that the Greeks nested in ? 

answer: cities like Alexandria, Antioch and Seleucia.
Title: Greeks
Context: This age saw the Greeks move towards larger cities and a reduction in the importance of the city-state. These larger cities were parts of the still larger Kingdoms of the Diadochi. Greeks, however, remained aware of their past, chiefly through the study of the works of Homer and the classical authors. An important factor in maintaining Greek identity was contact with barbarian (non-Greek) peoples, which was deepened in the new cosmopolitan environment of the multi-ethnic Hellenistic kingdoms. This led to a strong desire among Greeks to organize the transmission of the Hellenic paideia to the next generation. Greek science, technology and mathematics are generally considered to have reached their peak during the Hellenistic period.

question: With the secession away from the smaller communities in the Grecian world, what living situation became of great importance ? 

answer: the Greeks move towards larger cities and a reduction in the importance of the city-state.

question: The kingdoms of Diadochi was comprised of what ? 

answer: larger cities were parts of the still larger Kingdoms of the Diadochi.

question: How did the cites remind themselves of their beginnings ? 

answer: Greeks, however, remained aware of their past, chiefly through the study of the works of Homer and the classical authors.

question: What did the Greeks wants to be imparted to their descendants ? 

answer: the transmission of the Hellenic paideia to the next generation.

question: What academia was heightened during this time of Hellenism ? 

answer: Greek science, technology and mathematics are generally considered to have reached their peak during the Hellenistic period.
Title: Greeks
Context: In the religious sphere, this was a period of profound change. The spiritual revolution that took place, saw a waning of the old Greek religion, whose decline beginning in the 3rd century BC continued with the introduction of new religious movements from the East. The cults of deities like Isis and Mithra were introduced into the Greek world. Greek-speaking communities of the Hellenized East were instrumental in the spread of early Christianity in the 2nd and 3rd centuries, and Christianity's early leaders and writers (notably St Paul) were generally Greek-speaking, though none were from Greece. However, Greece itself had a tendency to cling to paganism and was not one of the influential centers of early Christianity: in fact, some ancient Greek religious practices remained in vogue until the end of the 4th century, with some areas such as the southeastern Peloponnese remaining pagan until well into the 10th century AD.

question: When did the religions of the past begin to dissipate ? 

answer: decline beginning in the 3rd century BC

question: What encouraged the change of faith ? 

answer: with the introduction of new religious movements from the East.

answer: Hellenized East were instrumental in the spread of early Christianity

question: What language are the Apostle's namely believed to have spoken ? 

answer: Christianity's early leaders and writers (notably St Paul) were generally Greek-speaking
Title: Greeks
Context: Of the new eastern religions introduced into the Greek world, the most successful was Christianity. From the early centuries of the Common Era, the Greeks identified as Romaioi ("Romans"), by that time the name ‘Hellenes’ denoted pagans. While ethnic distinctions still existed in the Roman Empire, they became secondary to religious considerations and the renewed empire used Christianity as a tool to support its cohesion and promoted a robust Roman national identity. Concurrently the secular, urban civilization of late antiquity survived in the Eastern Mediterranean along with Greco-Roman educational system, although it was from Christianity that the culture's essential values were drawn.

question: What alternative name were the Greeks known by ? 

answer: the Greeks identified as Romaioi ("Romans")

question: What did the label of  Hellenes come to stand for during the Common Era of Greece ? 

answer: the name ‘Hellenes’ denoted pagans

question: Did the Roman world consider one ethnocentric lineage to be a great concern ? 

answer: secondary to religious considerations

question: What imperative value was extolled from the Christian community to the Roman world ? 

answer: Greco-Roman educational system, although it was from Christianity that the culture's essential values were drawn.
