A scientist is a person who researches to advance knowledge in an area of the natural sciences .
106-467: Edward Tyson (20 January 1651 – 1 August 1708) was an English scientist and physician . He is commonly regarded as the founder of modern comparative anatomy , which compares the anatomy between species. Tyson was born the son of Edward Tyson at Clevedon , in Somerset . He became a BA from Oxford on 8 February 1670, an MA from Oxford on 4 November 1673, and an MD from Cambridge in 1678. He
212-419: A thesis (or dissertation) during an oral examination . To aid them in this endeavor, graduate students often work under the guidance of a mentor , usually a senior scientist, which may continue after the completion of their doctorates whereby they work as postdoctoral researchers . After the completion of their training, many scientists pursue careers in a variety of work settings and conditions. In 2017,
318-546: A 'strongman' was often the best solution. Athens fell under a tyranny in the second half of the 6th century BC. When this tyranny was ended, the Athenians founded the world's first democracy as a radical solution to prevent the aristocracy regaining power. A citizens' assembly (the Ecclesia ), for the discussion of city policy, had existed since the reforms of Draco in 621 BC; all citizens were permitted to attend after
424-404: A Monkey, an Ape, and a Man . In the book he came to the conclusion that the chimpanzee has more in common with man than with monkeys , particularly with respect to its brain . This work was republished in 1894 with an introduction by Bertram C. A. Windle and a short biography of Tyson. Tyson dissected a timber rattlesnake in 1683 and produced one of the earliest and most accurate descriptions of
530-480: A brass hook that was holding the leg in place. The leg twitched. Further experiments confirmed this effect, and Galvani was convinced that he was seeing the effects of what he called animal electricity, the life force within the muscles of the frog. At the University of Pavia , Galvani's colleague Alessandro Volta was able to reproduce the results, but was sceptical of Galvani's explanation. Lazzaro Spallanzani
636-500: A coalition of 31 Greek city states, including Athens and Sparta, determined to resist the Persian invaders. At the same time, Greek Sicily was invaded by a Carthaginian force. In 480 BC, the first major battle of the invasion was fought at Thermopylae , where a small rearguard of Greeks, led by three hundred Spartans, held a crucial pass guarding the heart of Greece for several days; at the same time Gelon , tyrant of Syracuse, defeated
742-625: A common term in the late 19th century in the United States and around the turn of the 20th century in Great Britain . By the twentieth century, the modern notion of science as a special brand of information about the world, practiced by a distinct group and pursued through a unique method, was essentially in place. Marie Curie became the first woman to win the Nobel Prize and the first person to win it twice. Her efforts led to
848-609: A council of elders (the Gerousia ) and magistrates specifically appointed to watch over the kings (the Ephors ). Only free, land-owning, native born men could be citizens entitled to the full protection of the law in a city-state. In most city-states, unlike the situation in Rome , social prominence did not allow special rights. Sometimes families controlled public religious functions, but this ordinarily did not give any extra power in
954-537: A cultivator of physics, I have called him a Physicist . We need very much a name to describe a cultivator of science in general. I should incline to call him a Scientist . Thus we might say, that as an Artist is a Musician, Painter, or Poet, a Scientist is a Mathematician, Physicist, or Naturalist. He also proposed the term physicist at the same time, as a counterpart to the French word physicien . Neither term gained wide acceptance until decades later; scientist became
1060-528: A decisive victory, and in 447 lost Boeotia again. Athens and Sparta signed the Thirty Years' Peace in the winter of 446/5, ending the conflict. Despite the treaty, Athenian relations with Sparta declined again in the 430s, and in 431 BC the Peloponnesian War began. The first phase of the war saw a series of fruitless annual invasions of Attica by Sparta, while Athens successfully fought
1166-436: A group of city-states allied themselves to defend Greece, the vast majority of poleis remained neutral, and after the Persian defeat, the allies quickly returned to infighting. Thus, the major peculiarities of the ancient Greek political system were its fragmented nature (and that this does not particularly seem to have tribal origin), and the particular focus on urban centers within otherwise tiny states. The peculiarities of

For this reason, Classical Greece is generally considered the cradle of Western civilization , the seminal culture from which the modern West derives many of its founding archetypes and ideas in politics, philosophy, science, and art. Classical antiquity in the Mediterranean region
1484-588: A profession, the scientist of today is widely recognized . However, there is no formal process to determine who is a scientist and who is not a scientist. Anyone can be a scientist in some sense. Some professions have legal requirements for their practice (e.g. licensure ) and some scientists are independent scientists meaning that they practice science on their own, but to practice science there are no known licensure requirements. In modern times, many professional scientists are trained in an academic setting (e.g., universities and research institutes ), mostly at
1590-760: A result of Epaminondas ' liberation of Messenia from Spartan rule, the helot system there came to an end and the helots won their freedom. However, it did continue to persist in Laconia until the 2nd century BC. For most of Greek history, education was private, except in Sparta. During the Hellenistic period, some city-states established public schools . Only wealthy families could afford a teacher. Boys learned how to read, write and quote literature. They also learned to sing and play one musical instrument and were trained as athletes for military service. They studied not for
1696-410: A result, scientific researchers often accept lower average salaries when compared with many other professions which require a similar amount of training and qualification. Scientists include experimentalists who mainly perform experiments to test hypotheses, and theoreticians who mainly develop models to explain existing data and predict new results. There is a continuum between two activities and
1802-523: A special type of slaves called helots . Helots were Messenians enslaved en masse during the Messenian Wars by the state and assigned to families where they were forced to stay. Helots raised food and did household chores so that women could concentrate on raising strong children while men could devote their time to training as hoplites . Their masters treated them harshly, and helots revolted against their masters several times. In 370/69 BC, as
1908-722: A war with the Roman Republic in the late 3rd century. Although the First Macedonian War was inconclusive, the Romans, in typical fashion, continued to fight Macedon until it was completely absorbed into the Roman Republic (by 149 BC). In the east, the unwieldy Seleucid Empire gradually disintegrated, although a rump survived until 64 BC, whilst the Ptolemaic Kingdom continued in Egypt until 30 BC when it too
2014-456: A widely regarded prestigious award, is awarded annually to those who have achieved scientific advances in the fields of medicine , physics , and chemistry . Some scientists have a desire to apply scientific knowledge for the benefit of people's health, the nations, the world, nature, or industries (academic scientist and industrial scientist ). Scientists tend to be less motivated by direct financial reward for their work than other careers. As
2120-684: A year, the Thirty had been overthrown. The first half of the fourth century saw the major Greek states attempt to dominate the mainland; none were successful, and their resulting weakness led to a power vacuum which would eventually be filled by Macedon under Philip II and then Alexander the Great. In the immediate aftermath of the Peloponnesian war, Sparta attempted to extend their own power, leading Argos, Athens, Corinth, and Thebes to join against them. Aiming to prevent any single Greek state gaining
2226-522: Is buried at St Dionis Backchurch . In 1680, Tyson studied a porpoise and established that it is a mammal . He noted that the convoluted structures of the brains were closer to those of land quadrupeds than those of fish. In 1698, he dissected a chimpanzee on display at the London docks, and as a result wrote a book, Orang-Outang, sive Homo Sylvestris: or, the Anatomy of a Pygmie Compared with that of

#17327942526142332-509: Is commonly considered to have begun in the 8th century BC (around the time of the earliest recorded poetry of Homer) and ended in the 6th century AD. Classical antiquity in Greece was preceded by the Greek Dark Ages ( c. 1200 – c. 800 BC ), archaeologically characterised by the protogeometric and geometric styles of designs on pottery. Following the Dark Ages was
2438-523: Is considered by many to be the "final frontier". There are many important discoveries to make regarding the nature of the mind and human thought , much of which still remains unknown. The number of scientists is vastly different from country to country. For instance, there are only four full-time scientists per 10,000 workers in India, while this number is 79 for the United Kingdom, and 85 for
2544-465: Is debated. Herodotus was succeeded by authors such as Thucydides , Xenophon , Demosthenes , Plato and Aristotle . Most were either Athenian or pro-Athenian, which is why far more is known about the history and politics of Athens than of many other cities. Their scope is further limited by a focus on political, military and diplomatic history, ignoring economic and social history. The archaic period, lasting from approximately 800 to 500 BC, saw

Regionalism and regional conflicts were prominent features of ancient Greece. Cities tended to be located in valleys between mountains, or on coastal plains, and dominated a certain area around them. In the south lay the Peloponnese , consisting of

He made important contributions to the experimental study of bodily functions and animal reproduction. Francesco Redi discovered that microorganisms can cause disease . Until the late 19th or early 20th century, scientists were still referred to as " natural philosophers " or "men of science". English philosopher and historian of science William Whewell coined
2862-479: Is unclear exactly how this change occurred. For instance, in Athens, the kingship had been reduced to a hereditary, lifelong chief magistracy ( archon ) by c. 1050 BC; by 753 BC this had become a decennial, elected archonship; and finally by 683 BC an annually elected archonship. Through each stage, more power would have been transferred to the aristocracy as a whole, and away from a single individual. Inevitably,

Written between the 450s and 420s BC, Herodotus' work reaches about a century into the past, discussing 6th century BC historical figures such as Darius I of Persia , Cambyses II and Psamtik III , and alluding to some 8th century BC persons such as Candaules . The accuracy of Herodotus' works
3074-428: The quadrivium —mathematics, including astronomy. Hence, the medieval analogs of scientists were often either philosophers or mathematicians. Knowledge of plants and animals was broadly the province of physicians. Science in medieval Islam generated some new modes of developing natural knowledge, although still within the bounds of existing social roles such as philosopher and mathematician. Many proto-scientists from
3180-674: The Archaic Period , beginning around the 8th century BC, which saw early developments in Greek culture and society leading to the Classical Period from the Persian invasion of Greece in 480 BC until the death of Alexander the Great in 323 BC. The Classical Period is characterized by a "classical" style, i.e. one which was considered exemplary by later observers, most famously in the Parthenon of Athens. Politically,
3286-710: The Archaic period , the Greek population grew beyond the capacity of the limited arable land of Greece proper, resulting in the large-scale establishment of colonies elsewhere: according to one estimate, the population of the widening area of Greek settlement increased roughly tenfold from 800 BC to 400 BC, from 800,000 to as many as 7 + 1 ⁄ 2 -10 million. This was not simply for trade, but also to found settlements. These Greek colonies were not, as Roman colonies were, dependent on their mother-city, but were independent city-states in their own right. Greeks settled outside of Greece in two distinct ways.

Following the Athenian surrender, Sparta installed an oligarchic regime, the Thirty Tyrants , in Athens, one of a number of Spartan-backed oligarchies which rose to power after the Peloponnesian war. Spartan predominance did not last: after only
3498-613: The British Association for the Advancement of Science had been complaining at recent meetings about the lack of a good term for "students of the knowledge of the material world collectively." Alluding to himself, he noted that "some ingenious gentleman proposed that, by analogy with artist , they might form [the word] scientist , and added that there could be no scruple in making free with this term since we already have such words as economist , and atheist —but this
3604-673: The Byzantine period. Three centuries after the decline of Mycenaean Greece during the Bronze Age Collapse , Greek urban poleis began to form in the 8th century BC, ushering in the Archaic period and the colonization of the Mediterranean Basin. This was followed by the age of Classical Greece , from the Greco-Persian Wars to the death of Alexander the Great in 323 BC, and which included
3710-576: The Delian League gradually transformed from a defensive alliance of Greek states into an Athenian empire, as Athens' growing naval power intimidated the other league states. Athens ended its campaigns against Persia in 450, after a disastrous defeat in Egypt in 454, and the death of Cimon in action against the Persians on Cyprus in 450. As the Athenian fight against the Persian empire waned, conflict grew between Athens and Sparta. Suspicious of
3816-698: The Golden Age of Athens and the Peloponnesian War . The unification of Greece by Macedon under Philip II and subsequent conquest of the Achaemenid Empire by Alexander the Great spread Hellenistic civilization across the Middle East. The Hellenistic Period is considered to have ended in 30 BC, when the last Hellenistic kingdom, Ptolemaic Egypt , was annexed by the Roman Republic . Classical Greek culture , especially philosophy, had
3922-485: The Islamic Golden Age are considered polymaths , in part because of the lack of anything corresponding to modern scientific disciplines . Many of these early polymaths were also religious priests and theologians : for example, Alhazen and al-Biruni were mutakallimiin ; the physician Avicenna was a hafiz ; the physician Ibn al-Nafis was a hafiz, muhaddith and ulema ; the botanist Otto Brunfels

Chalcidice was settled early on by southern Greek colonists and was considered part of the Greek world, while from the late 2nd millennium BC substantial Greek settlement also occurred on the eastern shores of the Aegean , in Anatolia . During

Astrology and astronomy became an important area of knowledge, and the role of astronomer/astrologer developed with the support of political and religious patronage . By the time of the medieval university system, knowledge was divided into the trivium —philosophy, including natural philosophy —and
4240-789: The Scientific Revolution that began in 16th century as the period when science in a recognizably modern form developed. It was not until the 19th century that sufficient socioeconomic changes had occurred for scientists to emerge as a major profession. Knowledge about nature in classical antiquity was pursued by many kinds of scholars. Greek contributions to science—including works of geometry and mathematical astronomy, early accounts of biological processes and catalogs of plants and animals, and theories of knowledge and learning—were produced by philosophers and physicians , as well as practitioners of various trades. These roles, and their associations with scientific knowledge, spread with
4346-506: The poleis grouped themselves into leagues, membership of which was in a constant state of flux. Later in the Classical period, the leagues would become fewer and larger, be dominated by one city (particularly Athens , Sparta and Thebes ); and often poleis would be compelled to join under threat of war (or as part of a peace treaty). Even after Philip II of Macedon conquered the heartlands of ancient Greece, he did not attempt to annex

4452-464: The 146 BC conquest of Greece after the Battle of Corinth. Macedonia became a Roman province while southern Greece came under the surveillance of Macedonia's prefect ; however, some Greek poleis managed to maintain a partial independence and avoid taxation. The Aegean Islands were added to this territory in 133 BC. Athens and other Greek cities revolted in 88 BC, and the peninsula was crushed by
4558-519: The British scientific journal Nature published the results of a large-scale survey of more than 5,700 doctoral students worldwide, asking them which sectors of the economy they would like to work in. A little over half of the respondents wanted to pursue a career in academia, with smaller proportions hoping to work in industry, government, and nonprofit environments. Other motivations are recognition by their peers and prestige. The Nobel Prize ,

The Persians were decisively defeated at sea by a primarily Athenian naval force at the Battle of Salamis , and on land in 479 BC at the Battle of Plataea . The alliance against Persia continued, initially led by the Spartan Pausanias but from 477 by Athens, and by 460 Persia had been driven out of the Aegean. During this long campaign,
4770-649: The Classical Period was dominated by Athens and the Delian League during the 5th century, but displaced by Spartan hegemony during the early 4th century BC, before power shifted to Thebes and the Boeotian League and finally to the League of Corinth led by Macedon . This period was shaped by the Greco-Persian Wars , the Peloponnesian War , and the Rise of Macedon . Following the Classical period

The war turned after Athenian victories led by Cleon at Pylos and Sphakteria , and Sparta sued for peace, but the Athenians rejected the proposal. The Athenian failure to regain control of Boeotia at Delium and Brasidas ' successes in northern Greece in 424 improved Sparta's position after Sphakteria. After
4982-668: The Greek city-states. It greatly widened the horizons of the Greeks and led to a steady emigration of the young and ambitious to the new Greek empires in the east. Many Greeks migrated to Alexandria, Antioch and the many other new Hellenistic cities founded in Alexander's wake, as far away as present-day Afghanistan and Pakistan , where the Greco-Bactrian Kingdom and the Indo-Greek Kingdom survived until
5088-460: The Greek colonies Syracusae ( Συράκουσαι ), Neapolis ( Νεάπολις ), Massalia ( Μασσαλία ) and Byzantion ( Βυζάντιον ). These colonies played an important role in the spread of Greek influence throughout Europe and also aided in the establishment of long-distance trading networks between the Greek city-states, boosting the economy of ancient Greece . Ancient Greece consisted of several hundred relatively independent city-states ( poleis ). This
5194-578: The Greek colony Sybaris in southern Italy, its allies, and the Serdaioi. In 499 BC, the Ionian city states under Persian rule rebelled against their Persian-supported tyrant rulers. Supported by troops sent from Athens and Eretria , they advanced as far as Sardis and burnt the city before being driven back by a Persian counterattack. The revolt continued until 494, when the rebelling Ionians were defeated. Darius did not forget that Athens had assisted
5300-420: The Greek system are further evidenced by the colonies that they set up throughout the Mediterranean , which, though they might count a certain Greek polis as their 'mother' (and remain sympathetic to her), were completely independent of the founding city. Inevitably smaller poleis might be dominated by larger neighbors, but conquest or direct rule by another city-state appears to have been quite rare. Instead
5406-815: The Greeks began 250 years of expansion, settling colonies in all directions. To the east, the Aegean coast of Asia Minor was colonized first, followed by Cyprus and the coasts of Thrace , the Sea of Marmara and south coast of the Black Sea . Eventually, Greek colonization reached as far northeast as present-day Ukraine and Russia ( Taganrog ). To the west the coasts of Illyria , Southern Italy (called " Magna Graecia ") were settled, followed by Southern France , Corsica , and even eastern Spain . Greek colonies were also founded in Egypt and Libya . Modern Syracuse , Naples , Marseille and Istanbul had their beginnings as

#17327942526145512-423: The Greeks were very aware of their tribal origins; Herodotus was able to extensively categorise the city-states by tribe. Yet, although these higher-level relationships existed, they seem to have rarely had a major role in Greek politics. The independence of the poleis was fiercely defended; unification was something rarely contemplated by the ancient Greeks. Even when, during the second Persian invasion of Greece,

Though heavily outnumbered, the Athenians—supported by their Plataean allies—defeated the Persian hordes at the Battle of Marathon , and the Persian fleet turned tail. Ten years later, a second invasion was launched by Darius' son Xerxes . The city-states of northern and central Greece submitted to the Persian forces without resistance, but

He conquered Persia, defeating Darius III at the Battle of Issus in 333 BC, and after the Battle of Gaugamela in 331 BC proclaimed himself king of Asia. From 329 BC he led expeditions to Bactria and then India; further plans to invade Arabia and North Africa were halted by his death in 323 BC. The period from

Greece was a key eastern province of the Roman Empire, as the Roman culture had long been in fact Greco-Roman . The Greek language served as a lingua franca in the East and in Italy , and many Greek intellectuals such as Galen would perform most of their work in Rome . The territory of Greece

The figure included twice as many men as women. Of that total, 17% worked in academia, that is, at universities and undergraduate institutions, and men held 53% of those positions. 5% of scientists worked for
6042-579: The ancient Greeks did not think in terms of race . Most families owned slaves as household servants and laborers, and even poor families might have owned a few slaves. Owners were not allowed to beat or kill their slaves. Owners often promised to free slaves in the future to encourage slaves to work hard. Unlike in Rome, freedmen did not become citizens. Instead, they were mixed into the population of metics , which included people from foreign countries or other city-states who were officially allowed to live in

After a failed coup led by Cylon of Athens around 636 BC, Draco was appointed to establish a code of laws in 621. This failed to reduce the political tension between the poor and the elites, and in 594 Solon was given the authority to enact another set of reforms, which attempted to balance

The absence of powerful states in Greece after the collapse of Mycenaean power, and the geography of Greece, where many settlements were separated from their neighbours by mountainous terrain, encouraged the development of small independent city-states. Several Greek states saw tyrants rise to power in this period, most famously at Corinth from 657 BC. The period also saw

These include cosmology and biology , especially molecular biology and the human genome project. Other areas of active research include the exploration of matter at the scale of elementary particles as described by high-energy physics , and materials science , which seeks to discover and design new materials. Others choose to study brain function and neurotransmitters , which

By 371 BC, Thebes was in the ascendancy, defeating Sparta at the Battle of Leuctra , killing the Spartan king Cleombrotus I , and invading Laconia. Further Theban successes against Sparta in 369 led to Messenia gaining independence; Sparta never recovered from

Towards the end of the archaic period, Sparta began to build a series of alliances, the Peloponnesian League , with cities including Corinth , Elis , and Megara , isolating Messenia and reinforcing Sparta's position against Argos , the other major power in the Peloponnese. Other alliances in the sixth century included those between Elis and Heraea in the Peloponnese; and between

The city-states within Greece formed themselves into two leagues; the Achaean League (including Corinth and Argos) and the Aetolian League (including Sparta and Athens). For much of the period until the Roman conquest, these leagues were at war, often participating in the conflicts between the Diadochi (the successor states to Alexander's empire). The Antigonid Kingdom became involved in

Soon after the Athenian defeat in Syracuse, Athens' Ionian allies began to rebel against the Delian league, while Persia began to once again involve itself in Greek affairs on the Spartan side. Initially the Athenian position continued relatively strong, with important victories at Cyzicus in 410 and Arginusae in 406. However, in 405 the Spartan Lysander defeated Athens in

Antigonus attempted to expand his territory by attacking the other successor kingdoms until they joined against him, and he was killed at the Battle of Ipsus in 301 BC. His son Demetrius spent many years in Seleucid captivity, and his son, Antigonus II , only reclaimed the Macedonian throne around 276. Meanwhile, the Seleucid kingdom gave up territory in

Scientist and engineering statistics are usually intertwined, but they indicate that women enter the field far less than men, though this gap is narrowing. The number of science and engineering doctorates awarded to women rose from
8056-469: The founding of Greek colonies around the Mediterranean, with Euboean settlements at Al-Mina in the east as early as 800 BC, and Ischia in the west by 775. Increasing contact with non-Greek peoples in this period, especially in the Near East, inspired developments in art and architecture, the adoption of coinage, and the development of the Greek alphabet. Athens developed its democratic system over
8162-576: The government. In Athens, the population was divided into four social classes based on wealth. People could change classes if they made more money. In Sparta, all male citizens were called homoioi , meaning "peers". However, Spartan kings, who served as the city-state's dual military and religious leaders, came from two families. Women in Ancient Greece appear to have primarily performed domestic tasks, managed households, and borne and reared children. Slaves had no power or status. Slaves had
8268-431: The ideas behind computers , and some of the foundations of statistical mechanics and quantum mechanics . Many mathematically inclined scientists, including Galileo , were also musicians . There are many compelling stories in medicine and biology , such as the development of ideas about the circulation of blood from Galen to Harvey . Some scholars and historians attributes Christianity to having contributed to
8374-547: The increasing Athenian power funded by the Delian League, Sparta offered aid to reluctant members of the League to rebel against Athenian domination. These tensions were exacerbated in 462 BC when Athens sent a force to aid Sparta in overcoming a helot revolt, but this aid was rejected by the Spartans. In the 450s, Athens took control of Boeotia, and won victories over Aegina and Corinth. However, Athens failed to win
8480-520: The internal anatomy of snakes. He was the first to describe the loreal pits of the Crotalinae . Tyson however did not recognize its heat-sensing function, thinking it was a hearing organ. Scientist In classical antiquity , there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy , a precursor of natural science . Though Thales ( c. 624–545 BC)
8586-522: The level of graduate schools . Upon completion, they would normally attain an academic degree , with the highest degree being a doctorate such as a Doctor of Philosophy (PhD). Although graduate education for scientists varies among institutions and countries, some common training requirements include specializing in an area of interest, publishing research findings in peer-reviewed scientific journals and presenting them at scientific conferences , giving lectures or teaching , and defending
8692-514: The loss of Messenia's fertile land and the helot workforce it provided. The rising power of Thebes led Sparta and Athens to join forces; in 362 they were defeated by Thebes at the Battle of Mantinea . In the aftermath of Mantinea, none of the major Greek states were able to dominate. Though Thebes had won the battle, their general Epaminondas was killed, and they spent the following decades embroiled in wars with their neighbours; Athens, meanwhile, saw its second naval alliance, formed in 377, collapse in
8798-495: The mid-350s. The power vacuum in Greece after the Battle of Mantinea was filled by Macedon, under Philip II . In 338 BC, he defeated a Greek alliance at the Battle of Chaeronea , and subsequently formed the League of Corinth . Philip planned to lead the League to invade Persia, but was murdered in 336 BC. His son Alexander the Great was left to fulfil his father's ambitions. After campaigns against Macedon's western and northern enemies, and those Greek states that had broken from
8904-529: The period of Christianization during the later 4th to early 6th centuries AD, consummated by the closure of the Academy of Athens by Justinian I in 529. The historical period of ancient Greece is unique in world history as the first period attested directly in comprehensive, narrative historiography , while earlier ancient history or protohistory is known from much more fragmentary documents such as annals, king lists, and pragmatic epigraphy . Herodotus
9010-410: The power of the rich and the poor. In the middle of the sixth century, Pisistratus established himself as a tyrant, and after his death in 527 his son Hippias inherited his position; by the end of the sixth century he had been overthrown and Cleisthenes carried out further democratising reforms. In Sparta, a political system with two kings, a council of elders , and five ephors developed over
9116-617: The reforms of Solon (early 6th century), but the poorest citizens could not address the assembly or run for office. With the establishment of the democracy, the assembly became the de jure mechanism of government; all citizens had equal privileges in the assembly. However, non-citizens, such as metics (foreigners living in Athens) or slaves , had no political rights at all. After the rise of democracy in Athens, other city-states founded democracies. However, many retained more traditional forms of government. As so often in other matters, Sparta
9222-420: The regions of Laconia (southeast), Messenia (southwest), Elis (west), Achaia (north), Korinthia (northeast), Argolis (east), and Arcadia (center). These names survive to the present day as regional units of modern Greece , though with somewhat different boundaries. Mainland Greece to the north, nowadays known as Central Greece , consisted of Aetolia and Acarnania in the west, Locris , Doris , and Phocis in
9328-518: The right to have a family and own property, subject to their master's goodwill and permission, but they had no political rights. By 600 BC, chattel slavery had spread in Greece. By the 5th century BC, slaves made up one-third of the total population in some city-states. Between 40–80% of the population of Classical Athens were slaves. Slaves outside of Sparta almost never revolted because they were made up of too many nationalities and were too scattered to organize. However, unlike later Western culture ,
9434-427: The rise of the Scientific Revolution . During the age of Enlightenment, Luigi Galvani , the pioneer of bioelectromagnetics , discovered animal electricity. He discovered that a charge applied to the spinal cord of a frog could generate muscular spasms throughout its body. Charges could make frog legs jump even if the legs were no longer attached to a frog. While cutting a frog leg, Galvani's steel scalpel touched
9540-504: The same time as Leibniz ). He provided a comprehensive formulation of classical mechanics and investigated light and optics. Fourier founded a new branch of mathematics — infinite, periodic series — studied heat flow and infrared radiation , and discovered the greenhouse effect . Girolamo Cardano , Blaise Pascal Pierre de Fermat , Von Neumann , Turing , Khinchin , Markov and Wiener , all mathematicians, made major contributions to science and probability theory , including
9646-448: The state. City-states legally owned slaves. These public slaves had a larger measure of independence than slaves owned by families, living on their own and performing specialized tasks. In Athens, public slaves were trained to look out for counterfeit coinage , while temple slaves acted as servants of the temple's deity and Scythian slaves were employed in Athens as a police force corralling citizens to political functions. Sparta had
9752-647: The term scientist in 1833, and it first appeared in print in Whewell's anonymous 1834 review of Mary Somerville 's On the Connexion of the Physical Sciences published in the Quarterly Review . Whewell wrote of "an increasing proclivity of separation and dismemberment" in the sciences; while highly specific terms proliferated—chemist, mathematician, naturalist—the broad term "philosopher"
9858-695: The territories they controlled. The most important of these rulers in the decades after Alexander's death were Antigonus I and his son Demetrius in Macedonia and the rest of Greece, Ptolemy in Egypt, and Seleucus I in Syria and the former Persian empire; smaller Hellenistic kingdoms included the Attalids in Anatolia and the Greco-Bactrian kingdom . In the early part of the Hellenistic period,
9964-515: The territory or unify it into a new province, but compelled most of the poleis to join his own Corinthian League . Initially many Greek city-states seem to have been petty kingdoms; there was often a city official carrying some residual, ceremonial functions of the king ( basileus ), e.g., the archon basileus in Athens. However, by the Archaic period and the first historical consciousness, most had already become aristocratic oligarchies . It
10070-455: The thermometer and telescope which allowed him to observe and clearly describe the solar system. Descartes was not only a pioneer of analytic geometry but formulated a theory of mechanics and advanced ideas about the origins of animal movement and perception . Vision interested the physicists Young and Helmholtz , who also studied optics , hearing and music . Newton extended Descartes's mathematics by inventing calculus (at
10176-626: The time of Alexander I of Macedon , the Argead kings of Macedon started to expand into Upper Macedonia , lands inhabited by independent Macedonian tribes like the Lyncestae , Orestae and the Elimiotae and to the west, beyond the Axius river , into Eordaia , Bottiaea , Mygdonia , and Almopia , regions settled by Thracian tribes. To the north of Macedonia lay various non-Greek peoples such as
10282-539: Was a notable exception to the rest of Greece, ruled through the whole period by not one, but two hereditary monarchs. This was a form of diarchy . The Kings of Sparta belonged to the Agiads and the Eurypontids, descendants respectively of Eurysthenes and Procles . Both dynasties' founders were believed to be twin sons of Aristodemus , a Heraclid ruler. However, the powers of these kings were held in check by both
10388-460: Was a situation unlike that in most other contemporary societies, which were either tribal or kingdoms ruling over relatively large territories. Undoubtedly, the geography of Greece —divided and sub-divided by hills, mountains, and rivers—contributed to the fragmentary nature of ancient Greece. On the one hand, the ancient Greeks had no doubt that they were "one people"; they had the same religion , same basic culture, and same language. Furthermore,
10494-659: Was a theologian and historian of Protestantism; the astronomer and physician Nicolaus Copernicus was a priest. During the Italian Renaissance scientists like Leonardo da Vinci , Michelangelo , Galileo Galilei and Gerolamo Cardano have been considered the most recognizable polymaths. During the Renaissance , Italians made substantial contributions in science. Leonardo da Vinci made significant discoveries in paleontology and anatomy. The Father of modern Science, Galileo Galilei , made key improvements on
10600-870: Was admitted to the College of Physicians on 30 September 1680 and as a Fellow in April 1683. In 1684 he was appointed physician and governor to the Bethlem Hospital in London (the first mental hospital in Britain and the second in Europe). He is credited with changing the hospital from a zoo of sorts to a place intended to assist its inmates. He was elected a Fellow of the Royal Society in November 1679. He
10706-632: Was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods, it was not until the 19th century that the term scientist came into regular use after it was coined by the theologian , philosopher , and historian of science William Whewell in 1833. The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natural historians, natural theologians, engineers, and others who contributed to
10812-752: Was conquered by the Romans. The Aetolian league grew wary of Roman involvement in Greece, and sided with the Seleucids in the Roman–Seleucid War ; when the Romans were victorious, the league was effectively absorbed into the Republic. Although the Achaean league outlasted both the Aetolian league and Macedon, it was also soon defeated and absorbed by the Romans in 146 BC, bringing Greek independence to an end. The Greek peninsula came under Roman rule during
10918-417: Was in permanent settlements founded by Greeks, which formed as independent poleis. The second form was in what historians refer to as emporia ; trading posts which were occupied by both Greeks and non-Greeks and which were primarily concerned with the manufacture and sale of goods. Examples of this latter type of settlement are found at Al Mina in the east and Pithekoussai in the west. From about 750 BC
11024-417: Was no longer satisfactory to group together those who pursued science, without the caveats of "natural" or "experimental" philosopher. Whewell compared these increasing divisions with Somerville's aim of "[rendering] a most important service to science" "by showing how detached branches have, in the history of science, united by the discovery of general principles." Whewell reported in his review that members of
11130-512: Was not generally palatable". Whewell proposed the word again more seriously (and not anonymously) in his 1840 The Philosophy of the Inductive Sciences : The terminations ize (rather than ise ), ism , and ist , are applied to words of all origins: thus we have to pulverize , to colonize , Witticism , Heathenism , Journalist , Tobacconist . Hence we may make such words when they are wanted. As we cannot use physician for
11236-542: Was the Hellenistic period (323–146 BC), during which Greek culture and power expanded into the Near and Middle East from the death of Alexander until the Roman conquest. Roman Greece is usually counted from the Roman victory over the Corinthians at the Battle of Corinth in 146 BC to the establishment of Byzantium by Constantine as the capital of the Roman Empire in 330 AD. Finally, Late Antiquity refers to
