  China
  China (ⁱ/ˈtʃaɪnə/; Chinese: 中国; pinyin: Zhōngguó; see also Names of China), officially the People's Republic of China (PRC), is the world's most-populous country, with a population of over 1.3 billion. Covering approximately 9.6 million square kilometres, the East Asian state is the world's second-largest country by land area, and the third- or fourth-largest in total area, depending on the definition of total area.
  The People's Republic of China is a single-party state governed by the Communist Party of China. It exercises jurisdiction over 22 provinces, five autonomous regions, four directly controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and two mostly self-governing special administrative regions (Hong Kong and Macau). Its capital city is Beijing. The PRC also claims Taiwan—which is controlled by the Republic of China (ROC), a separate political entity—as its 23rd province, a claim controversial due to the complex political status of Taiwan and the unresolved Chinese Civil War. The PRC government denies the legitimacy of the ROC.

• Powers of Ten
  Powers of Ten is a 1968 American documentary film written and directed by Charles and Ray Eames. The film depicts the relative scale of the Universe in factors of ten (see also logarithmic scale and order of magnitude). The film is an adaptation of the book Cosmic View (1957) by Dutch educator Kees Boeke, and more recently is the basis of a new book version. Both adaptations, film and book, follow the form of the Boeke original, adding color and photography to the black and white drawings employed by Boeke in his seminal work.
  The film was rereleased in 1977. In 1998, "Powers of Ten" was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
  The film begins with an overhead view of a man and woman picnicking on a lawn — a one-meter-square overhead image of the figures on a blanket. The viewpoint, accompanied by expository voiceover by Philip Morrison, then slowly zooms out to a view ten meters across (or 10¹ m in scientific notation). The zoom-out continues (at a rate of one power of ten per 10 seconds), to a view of 100 meters (10² m), then 1 kilometer (10³ m), and so on, increasing the perspective—the picnic is revealed to be taking place in Burnham Park, near Soldier Field on Chicago's lakefront—and continuing to zoom out to a field of view of 10²⁴ meters, or the size of the observable universe. The camera then zooms back in at a rate of a power of ten per 2 seconds to the picnic, and then slows back down to its original rate into the man's hand, to views of negative powers of ten—10⁻¹ m (10 centimeters), and so forth—until the camera comes to quarks in a proton of a carbon atom at 10⁻¹⁶ meter.

  Al-Kindi
  Abu Yusuf Yaʻqūb ibn Isḥāq al-Sabbah al-Kindī (Arabic: ابو يوسف يعقوب بن اسحاق الصبّاح الكندي‎, Latin: Alkindus) (c. 801–873 CE), known as "the Philosopher of the Arabs", was a Muslim Arab philosopher, 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 and educated in Kufa, before going to pursue further studies 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 lead 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.

  Albert Einstein
  Albert Einstein ( /ˈælbərt ˈaɪnstaɪn/; German: [ˈalbɐt ˈaɪnʃtaɪn] ( listen); 14 March 1879 – 18 April 1955) was a German theoretical physicist who developed the theory of general relativity, effecting a revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics. While best known for his mass–energy equivalence formula E = mc² (which has been dubbed "the world's most famous equation"), he received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect". The latter was pivotal in establishing quantum theory within physics.
  Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on the general theory of relativity. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the structure of the universe as a whole.

  Albumasar
  Abū Maʿshar, Jaʿfar ibn Muḥammad al-Balkhī (also known as al-Falakī or Ibn Balkhī, Latinized as Albumasar, Albusar, or Albuxar) (10 August 787 in Balkh, Khurasan – 9 March 886 in Wāsiṭ, Iraq), was a Persian astrologer, astronomer, and Islamic philosopher, thought to be the greatest astrologer of the Abbasid court in Baghdad. He was not a major innovator and as an astrologer he was not intellectually rigorous. Nevertheless, he wrote a number of practical manuals on astrology that profoundly influenced Muslim intellectual history and, through translations, that of western Europe and Byzantium.
  Richard Lemay has argued that the writings of Albumasar were very likely the single most important original source of Aristotle's theories of nature for European scholars, starting a little before the middle of the 12th century.
  It was not until later in the 12th century that the original books of Aristotle on nature began to become available in Latin. The works of Aristotle on logic had been known earlier, and Aristotle was generally recognized as "the master of logic." But during the course of the 12th century, Aristotle was transformed into the "master of those who know," and in particular a master of natural philosophy. It is notable that the work of Albumasar (or Balkhi), in question, is a treatise on astrology. Its Latin title is "Introductorium in Astronomiam", a translation of the Arabic Kitab al-mudkhal al-kabir ila 'ilm ahkam an-nujjum, written in Baghdad in the year 848 A.D. It was translated into Latin first by John of Seville in 1133, and again, less literally and abridged, by Herman of Carinthia in 1140 A.D. Amir Khusrav mentions that Abu Maʿshar came to Benaras (Varanasi) and studied astronomy there for ten years.

  Alexander Friedmann
  Alexander Alexandrovich Friedmann (also spelled Friedman or Fridman, Russian: Алекса́ндр Алекса́ндрович Фри́дман) (June 29 (17 old style) by himself, June 16 (4 old style) by J. O'Conor in 1888, Saint Petersburg, Russian Empire – September 16, 1925, Leningrad, USSR) was a Russian and Soviet physicist and mathematician.
  Alexander Friedmann was born to the composer and ballet dancer Alexander Friedmann (who was a son of baptized Jewish cantonist) and the pianist Ludmila Voyachek. He lived much of his life in Saint Petersburg. He fought in World War I (on behalf of Imperial Russia) as a bomber and later lived through the Russian Revolution of 1917.
  Friedmann obtained his degree in St. Petersburg State University (1910), became a lecturer in St.-Petersburg State College of Mines, and a professor in Perm State University in 1918.
  In June 1925 he was given the job of the director of Main Geophysical Observatory in Leningrad. In July 1925 he participated in a record-setting balloon flight, reaching the elevation of 7,400 m (24,300 ft).

  Ali Qushji
  Ala al-Dīn Ali ibn Muhammed (1403 – 16 December 1474), known as Ali Qushji (Ottoman Turkish/Persian language: علی قوشچی, kuşçu - falconer in Turkish;Latin: Ali Kushgii), was a Turkic or Persianastronomer, mathematician and physicist originally from Samarkand, who settled in the Ottoman Empire some time before 1472. As a disciple of Ulugh Beg, he is best known for the development of astronomical physics independent from natural philosophy, and for providing empirical evidence for the Earth's rotation in his treatise, Concerning the Supposed Dependence of Astronomy upon Philosophy. In addition to his contributions to Ulugh Beg's famous work Zij-i-Sultani and to the founding of Sahn-ı Seman University^{[citation needed]}, one of the first madrasahs in the Ottoman Empire, Ali Qushji was also the author of several scientific works and textbooks on astronomy.
  Ali Qushji was born in 1403 in the city of Samarkand, in present-day Uzbekistan. His full name at birth was Ala al-Dīn Ali ibn Muhammed al-Qushji. The last name Qushji derived from the Turkish term kuşçu - the falconer - due to the fact that Ali's father Muhammad was the royal falconer of Ulugh Beg.

  Anaxagoras
  Anaxagoras (Greek: Ἀναξαγόρας, Anaxagoras, "lord of the assembly"; c. 500 BC – 428 BC) was a Pre-Socratic Greek philosopher. Born in Clazomenae in Asia Minor, Anaxagoras was the first philosopher to bring philosophy from Ionia to Athens. He attempted to give a scientific account of eclipses, meteors, rainbows, and the sun, which he described as a fiery mass larger than the Peloponnese. According to Diogenes Laertius and Plutarch he fled to Lampsacus due to a backlash against his pupil Pericles.
  Anaxagoras is famous for introducing the cosmological concept of Nous (mind), as an ordering force. He regarded material substance as an infinite multitude of imperishable primary elements, referring all generation and disappearance to mixture and separation respectively.
  Anaxagoras appears to have had some amount of property and prospects of political influence in his native town of Clazomenae in Asia Minor. However, he supposedly surrendered both of these out of a fear that they would hinder his search for knowledge. Valerius Maximus preserves a different tradition: Anaxagoras, coming home from a long voyage, found his property in ruin, and said: "If this had not perished, I would have." A sentence, denoted by Maximus, as being "possessed of sought-after wisdom!". Although a Greek, he may have been a soldier of the Persian army when Clazomenae was suppressed during the Ionian Revolt.

  Anaximander
  Anaximander ( /əˌnæksɨˈmændər/; Greek: Ἀναξίμανδρος, Anaximandros; c. 610 – c. 546 BC) was a pre-Socratic Greek philosopher who lived in Miletus, a city of Ionia; Milet in modern Turkey. He belonged to the Milesian school and learned the teachings of his master Thales. He succeeded Thales and became the second master of that school where he counted Anaximenes and arguably, Pythagoras amongst his pupils.
  Little of his life and work is known today. According to available historical documents, he is the first philosopher known to have written down his studies, although only one fragment of his work remains. Fragmentary testimonies found in documents after his death provide a portrait of the man.
  Anaximander was one of the earliest Greek thinkers at the start of the Axial Age, the period from approximately 700 BC to 200 BC, during which similarly revolutionary thinking appeared in China, India, Iran, the Near East, and Ancient Greece. He was an early proponent of science and tried to observe and explain different aspects of the universe, with a particular interest in its origins, claiming that nature is ruled by laws, just like human societies, and anything that disturbs the balance of nature does not last long. Like many thinkers of his time, Anaximander's contributions to philosophy relate to many disciplines. In astronomy, he tried to describe the mechanics of celestial bodies in relation to the Earth. In physics, his postulation that the indefinite (or apeiron) was the source of all things led Greek philosophy to a new level of conceptual abstraction. His knowledge of geometry allowed him to introduce the gnomon in Greece. He created a map of the world that contributed greatly to the advancement of geography. He was also involved in the politics of Miletus and was sent as a leader to one of its colonies.

  Andrei Linde
  Andrei Dmitriyevich Linde (Russian: Андрей Дмитриевич Линде; born March 2, 1948) is a Russian-American theoretical physicist and professor of Physics at Stanford University. Dr. Linde is best known for his work on the concept of the inflationary universe. He received his Bachelor of Science degree from Moscow State University. In 1975, Linde was awarded a Ph.D. from the Lebedev Physical Institute in Moscow. Among the various awards he's received for his work on inflation, in 2002 he was awarded the Dirac Medal, along with Alan Guth of MIT and Paul Steinhardt of Princeton University.
  Linde is best known for proposing "eternal chaotic inflation" to explain a number of problems in cosmology. This variant of cosmic inflation proposes that the false vacuum is eternally inflating in exponential growth powered by repulsive constant random zero point dark energy of negative pressure. This false vacuum is like supersaturated steam in which liquid bubbles of more stable vacuum form with Higgs-Goldstone fields that describe the cohering of most of the pre-inflationary random dark energy into the smooth fabric of curved spacetime. Our universe is only a small causal part of a single bubble, and there are 10^10^10^7 bubbles. In fact, there are 10^10^10^7 of universes like ours on a single bubble which is more like an expanding infinite sheet than a finite spherical surface (suppressing 1 space dimension for ease of visualization).

  Archimedes
  Archimedes of Syracuse (Ancient Greek: Ἀρχιμήδης; c. 287 BC – c. 212 BC) was a Greek mathematician, physicist, engineer, inventor, and astronomer. Although few details of his life are known, he is regarded as one of the leading scientists in classical antiquity. Among his advances in physics are the foundations of hydrostatics, statics and an explanation of the principle of the lever. He is credited with designing innovative machines, including siege engines and the screw pump that bears his name. Modern experiments have tested claims that Archimedes designed machines capable of lifting attacking ships out of the water and setting ships on fire using an array of mirrors.
  Archimedes is generally considered to be the greatest mathematician of antiquity and one of the greatest of all time. He used the method of exhaustion to calculate the area under the arc of a parabola with the summation of an infinite series, and gave a remarkably accurate approximation of pi. He also defined the spiral bearing his name, formulae for the volumes of surfaces of revolution and an ingenious system for expressing very large numbers.

  Aristarchus of Samos
  Aristarchus (310 BC – ca. 230 BC), was an ancient Greek astronomer and mathematician who presented the first known model that placed the Sun at the center of the known universe with the Earth revolving around it (see Solar system). He was influenced by Philolaus of Croton, but he identified the "central fire" with the Sun, and put the other planets in their correct order of distance around the Sun. His astronomical ideas were often rejected in favor of the geocentric theories of Aristotle and Ptolemy.
  His name is Ἀρίσταρχος in Greek letters, which transliterates to Aristarchos. He was born on the island of Samos, in the eastern Aegean Sea.
  Though the original text has been lost, a reference in Archimedes' book The Sand Reckoner (Archimedis Syracusani Arenarius & Dimensio Circuli) describes another work by Aristarchus in which he advanced the heliocentric model as an alternative hypothesis. Archimedes wrote:
  Aristarchus thus believed the stars to be very far away, and that in consequence there was no observable parallax, that is, a movement of the stars relative to each other as the Earth moves around the Sun. The stars are much farther away than was generally assumed in ancient times; and since stellar parallax is only detectable with telescopes, his speculation although accurate was unprovable at the time.

  Aristotle
  Aristotle (Ancient Greek: Ἀριστοτέλης, Aristotélēs) (384 BC – 322 BC) was a Greek philosopher and polymath, a student of Plato and teacher of Alexander the Great. His writings cover many subjects, including physics, metaphysics, poetry, theater, music, logic, rhetoric, linguistics, politics, government, ethics, biology, and zoology. Together with Plato and Socrates (Plato's teacher), Aristotle is one of the most important founding figures in Western philosophy. Aristotle's writings were the first to create a comprehensive system of Western philosophy, encompassing morality, aesthetics, logic, science, politics, and metaphysics.
  Aristotle's views on the physical sciences profoundly shaped medieval scholarship, and their influence extended well into the Renaissance, although they were ultimately replaced by Newtonian physics. In the zoological sciences, some of his observations were confirmed to be accurate only in the 19th century. His works contain the earliest known formal study of logic, which was incorporated in the late 19th century into modern formal logic. In metaphysics, Aristotelianism had a profound influence on philosophical and theological thinking in the Islamic and Jewish traditions in the Middle Ages, and it continues to influence Christian theology, especially the scholastic tradition of the Catholic Church. His ethics, though always influential, gained renewed interest with the modern advent of virtue ethics. All aspects of Aristotle's philosophy continue to be the object of active academic study today. Though Aristotle wrote many elegant treatises and dialogues (Cicero described his literary style as "a river of gold"), it is thought that the majority of his writings are now lost and only about one-third of the original works have survived.

  Arno Allan Penzias
  Arno Allan Penzias (born 26 April 1933) is an American physicist and Nobel laureate in physics.
  Penzias was born in Munich, Germany. At age six he was among the Jewish children evacuated to Britain as part of the Kindertransport rescue operation. Some time later, his parents also fled Nazi Germany for the U.S., and the family settled in the Garment District of New York City in 1940. In 1946, Penzias became a naturalized citizen of the United States. He graduated from Brooklyn Technical High School in 1951 and received a bachelor's degree from the City College of New York in 1954. From Columbia University, he received his Master's degree in 1958 and his Ph.D. in 1962.
  He went on to work at Bell Labs in Holmdel, New Jersey, where, with Robert Woodrow Wilson, he worked on ultra-sensitive cryogenic microwave receivers, intended for radio astronomy observations. In 1964, on building their most sensitive antenna/receiver system, the pair encountered radio noise which they could not explain. It was far less energetic than the radiation given off by the Milky Way, and it was isotropic, so they assumed their instrument was subject to interference by terrestrial sources. They tried, and then rejected, the hypothesis that the radio noise emanated from New York City. An examination of the microwave horn antenna showed it was full of pigeon droppings (which Penzias described as "white dielectric material"). After the pair removed the guano buildup, and the pigeons were shot (each physicist says the other ordered the deed), the noise remained. Having rejected all sources of interference, the pair published a paper announcing their findings. This was later identified by Robert Dicke as the cosmic microwave background radiation (CMB), the radio remnant of the Big Bang. This allowed astronomers to confirm the Big Bang, and to correct many of their previous assumptions about it.

  Aryabhata
  Aryabhata (IAST: Āryabhaṭa, Sanskrit: आर्यभट) (476–550 CE) was the first in the line of great mathematician-astronomers from the classical age of Indian mathematics and Indian astronomy. His most famous works are the Āryabhaṭīya (499 CE, when he was 23 years old) and the Arya-siddhanta.
  While there is a tendency to misspell his name as "Aryabhatta" by analogy with other names having the "bhatta" suffix, his name is properly spelled Aryabhata: every astronomical text spells his name thus, including Brahmagupta's references to him "in more than a hundred places by name". Furthermore, in most instances "Aryabhatta" does not fit the metre either.
  Aryabhata mentions in the Aryabhatiya that it was composed 3,630 years into the Kali Yuga, when he was 23 years old. This corresponds to 499 CE, and implies that he was born in 476
  Aryabhata was born in Taregna (literally, song of the stars), which is a small town in Bihar, India, about 30 km (19 mi) from Patna (then known as Pataliputra), the capital city of Bihar State. Evidences justify his birth there. In Taregna Aryabhata set up an Astronomical Observatory in the Sun Temple 6th century.

  Bernhard Riemann
  Georg Friedrich Bernhard Riemann [ˈʁiːman] ( listen) (September 17, 1826 – July 20, 1866) was an influential German mathematician who made lasting contributions to analysis, number theory and differential geometry, some of them enabling the later development of general relativity.
  Riemann was born in Breselenz, a village near Dannenberg in the Kingdom of Hanover in what is the Federal Republic of Germany today. His father, Friedrich Bernhard Riemann, was a poor Lutheran pastor in Breselenz who fought in the Napoleonic Wars. His mother, Charlotte Ebell, died before her children had reached adulthood. Riemann was the second of six children, shy, and suffered from numerous nervous breakdowns. Riemann exhibited exceptional mathematical skills, such as fantastic calculation abilities, from an early age but suffered from timidity and a fear of speaking in public.
  During 1840, Riemann went to Hanover to live with his grandmother and attend lyceum (middle school). After the death of his grandmother in 1842, he attended high school at the Johanneum Lüneburg. In high school, Riemann studied the Bible intensively, but he was often distracted by mathematics. His teachers were amazed by his adept ability to solve complicated mathematical operations, in which he often outstripped his instructor's knowledge. In 1846, at the age of 19, he started studying philology and theology in order to become a priest and help with his family's finances.

  Brahmagupta
  Brahmagupta (Sanskrit: ब्रह्मगुप्त;  listen (help·info)) (598–668 CE) was an Indian mathematician and astronomer who wrote many important works on mathematics and astronomy. His best known work is the Brāhmasphuṭasiddhānta (Correctly Established Doctrine of Brahma), written in 628 in Bhinmal. Its 25 chapters contain several unprecedented mathematical results.
  Brahmagupta is believed to have been born in 598 AD in Bhinmal city in the state of Rajasthan of Northwest India. In ancient times Bhillamala was the seat of power of the Gurjars. His father was Jisnugupta. He likely lived most of his life in Bhillamala (modern Bhinmal in Rajasthan) during the reign (and possibly under the patronage) of King Vyaghramukha. As a result, Brahmagupta is often referred to as Bhillamalacarya, that is, the teacher from Bhillamala. He was the head of the astronomical observatory at Ujjain, and during his tenure there wrote four texts on mathematics and astronomy: the Cadamekela in 624, the Brahmasphutasiddhanta in 628, the Khandakhadyaka in 665, and the Durkeamynarda in 672. The Brahmasphutasiddhanta (Corrected Treatise of Brahma) is arguably his most famous work. The historian al-Biruni (c. 1050) in his book Tariq al-Hind states that the Abbasid caliph al-Ma'mun had an embassy in India and from India a book was brought to Baghdad which was translated into Arabic as Sindhind. It is generally presumed that Sindhind is none other than Brahmagupta's Brahmasphuta-siddhanta.

  Chaldea or Chaldaea ( /kælˈdiːə/), from Greek Χαλδαία, Chaldaia; Akkadian māt Kaldu; Hebrew כשדים, Kaśdim;Aramaic: ܟܐܠܕܘ, Kaldo) was a marshy land located in modern-day southern Iraq which came to rule Babylon briefly. Tribes of settlers who arrived in the region from the 8th Century BC became known as the Chaldeans or the Chaldees. The Hebrew Bible uses the term כשדים (Kaśdim) and this is translated as Chaldaeans in the Septuagint.
  The short-lived 11th dynasty of the Kings of Babylon (6th century BC) is conventionally known to historians as the Chaldean Dynasty, although only the first four rulers of this dynasty were known to be Chaldeans, and the last ruler was known not to be. Their kingdom in the southern portion of Babylonia lay chiefly on the right bank of the Euphrates. Though the name came to be commonly used to refer to the whole of southern Mesopotamia, Chaldea proper was in fact the vast plain in the far south east formed by the deposits of the Euphrates and the Tigris, extending to about four hundred miles along the course of these rivers, and about a hundred miles in average width.

  China
  China (ⁱ/ˈtʃaɪnə/; Chinese: 中国; pinyin: Zhōngguó; see also Names of China), officially the People's Republic of China (PRC), is the world's most-populous country, with a population of over 1.3 billion. Covering approximately 9.6 million square kilometres, the East Asian state is the world's second-largest country by land area, and the third- or fourth-largest in total area, depending on the definition of total area.
  The People's Republic of China is a single-party state governed by the Communist Party of China. It exercises jurisdiction over 22 provinces, five autonomous regions, four directly controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and two mostly self-governing special administrative regions (Hong Kong and Macau). Its capital city is Beijing. The PRC also claims Taiwan—which is controlled by the Republic of China (ROC), a separate political entity—as its 23rd province, a claim controversial due to the complex political status of Taiwan and the unresolved Chinese Civil War. The PRC government denies the legitimacy of the ROC.

  Christiaan Huygens
  Christiaan Huygens, FRS (/ˈhaɪɡənz/; [ˈɦœyɣə(n)s] ( listen); 14 April 1629 – 8 July 1695) was a prominent Dutch mathematician, astronomer, physicist and horologist. His work included early telescopic studies elucidating the nature of the rings of Saturn and the discovery of its moon Titan, the invention of the pendulum clock and other investigations in timekeeping, and studies of both optics and the centrifugal force.
  Huygens achieved note for his argument that light consists of waves, now known as the Huygens–Fresnel principle, which two centuries later became instrumental in the understanding of wave-particle duality. He generally receives credit for his discovery of the centrifugal force, the laws for collision of bodies, for his role in the development of modern calculus and his original observations on sound perception (see repetition pitch).
  Christiaan Huygens was born in April 1629 at The Hague, the second son of Constantijn Huygens, (1596–1687), a friend of mathematician, philosopher and minor physicistRené Descartes, and of Suzanna van Baerle (deceased 1637), whom Constantijn had married on 6 April 1627. Christiaan studied law and mathematics at the University of Leiden and the College of Orange in Breda. After a stint as a diplomat, Huygens turned to science.

  Cicero
  Marcus Tullius Cicero ( /ˈsɪsɨroʊ/; Classical Latin: [ˈkɪkɛroː]; January 3, 106 BC – December 7, 43 BC; sometimes anglicized as Tully), was a Roman philosopher, statesman, lawyer, orator, political theorist, Roman consul and constitutionalist. He came from a wealthy municipal family of the equestrian order, and is widely considered one of Rome's greatest orators and prose stylists.
  He introduced the Romans to the chief schools of Greek philosophy and created a Latin philosophical vocabulary (with neologisms such as humanitas, qualitas, quantitas, and essentia) distinguishing himself as a linguist, translator, and philosopher.
  Petrarch's rediscovery of Cicero's letters is often credited for initiating the 14th-century Renaissance. According to Polish historian Tadeusz Zieliński, "Renaissance was above all things a revival of Cicero, and only after him and through him of the rest of Classical antiquity." The peak of Cicero's authority and prestige came during the eighteenth-century Enlightenment, and his impact on leading Enlightenment thinkers such as John Locke, David Hume, and Montesquieu was substantial. His works rank among the most influential in European culture, and today still constitute one of the most important bodies of primary material for the writing and revision of Roman history, especially the last days of the Roman Republic.

  Democritus
  Democritus (Greek: Δημόκριτος, Dēmokritos, "chosen of the people") (ca. 460 BC – ca. 370 BC) was an Ancient Greek philosopher born in Abdera, Thrace, Greece. He was an influential pre-Socratic philosopher and pupil of Leucippus, who formulated an atomic theory for the cosmos.
  His exact contributions are difficult to disentangle from his mentor Leucippus, as they are often mentioned together in texts. Their speculation on atoms, taken from Leucippus, bears a passing and partial resemblance to the nineteenth-century understanding of atomic structure that has led some to regard Democritus as more of a scientist than other Greek philosophers; however their ideas rested on very different bases. Largely ignored in ancient Athens, Democritus was nevertheless well known to his fellow northern-born philosopher Aristotle. Plato is said to have disliked him so much that he wished all his books burned. Many consider Democritus to be the "father of modern science".
  Democritus was born in the city of Abdera in Thrace, an Ionian colony of Teos, although some called him a Milesian. He was born in the 80th Olympiad (460–457 BC) according to Apollodorus of Athens, and although Thrasyllus placed his birth in 470 BC, the later date is probably more likely.John Burnet has argued that the date of 460 is "too early", since according to Diogenes Laërtius ix.41, Democritus said that he was a "young man (neos)" during Anaxagoras' old age (circa 440–428). It was said that Democritus' father was so wealthy that he received Xerxes on his march through Abdera. Democritus spent the inheritance which his father left him on travels into distant countries, to satisfy his thirst for knowledge. He traveled to Asia, and was even said to have reached India and Ethiopia.

  Edwin Hubble
  Edwin Powell Hubble (November 20, 1889 – September 28, 1953) was an American astronomer who is known for Hubble's law. He is incorrectly credited with the discovery of the existence of galaxies other than the Milky Way and galactic red shift- discoveries made by the astronomer Vesto Slipher in 1912. He popularized Vesto Slipher's discovery that the loss in frequency—the redshift—observed in the spectra of light from other galaxies increased in proportion to a particular galaxy's distance from Earth. This relationship which was based Slipher's data became known as Hubble's law. Vesto Slipher, the unsung hero of twentieth-century astronomy was the first to present his findings in a meeting of the American Astronomical Society in August 1914. Stephen Hawking wryly notes in his book the Universe in a Nutshell "Hubble heard the presentation". Due to Vesto Slipher's reserved and reticent personality, his discoveries are incorrectly credited to Hubble.
  Hubble doubted the Doppler shift interpretation of the observed redshift that had been proposed earlier by Vesto Slipher, whose data he used, and that led to the theory of the metric expansion of space. He tended to believe the frequency of any beam of light could, by some so far unknown means, be diminished ever stronger, the longer the beam travels through space.

  Empedocles
  Empedocles (pronounced: /ɛmˈpɛdəkliːz/; Ancient Greek: Ἐμπεδοκλῆς; Empedoklēs; Ancient Greek: [empedoklɛ̂ːs]; ca. 490–430 BC) was a Greek pre-Socratic philosopher and a citizen of Agrigentum, a Greek city in Sicily. Empedocles' philosophy is best known for being the originator of the cosmogenic theory of the four Classical elements. He also proposed powers called Love and Strife which would act as forces to bring about the mixture and separation of the elements. These physical speculations were part of a history of the universe which also dealt with the origin and development of life. Influenced by the Pythagoreans, he supported the doctrine of reincarnation. Empedocles is generally considered the last Greek philosopher to record his ideas in verse. Some of his work survives, more than in the case of any other Presocratic philosopher. Empedocles' death was mythologized by ancient writers, and has been the subject of a number of literary treatments.
  Empedocles was born, c. 490 BC, at Agrigentum (Acragas) in Sicily to a distinguished family. Very little is known about his life. His father Meto seems to have been instrumental in overthrowing the tyrant of Agrigentum, presumably Thrasydaeus in 470 BC. Empedocles continued the democratic tradition of his house by helping to overthrow the succeeding oligarchic government. He is said to have been magnanimous in his support of the poor; severe in persecuting the overbearing conduct of the aristocrats; and he even declined the sovereignty of the city when it was offered to him.

• Eudoxus of Cnidos
  Eudoxus of Cnidus (410 or 408 BC – 355 or 347 BC) was a Greek astronomer, mathematician, scholar and student of Plato. Since all his own works are lost, knowledge of him is obtained from secondary sources, such as Aratus's poem on astronomy. Theodosius of Bithynia's Sphaerics may be based on a work of Eudoxus.
  His name Eudoxus means "honored" or "of good repute" (in Greek Εὔδοξος, from eu "good" and doxa "opinion, belief, fame"). It is analogous to the Latin name Benedictus.
  Eudoxus's father Aeschines of Cnidus loved to watch stars at night. Eudoxus first travelled to Tarentum to study with Archytas, from whom he learned mathematics. While in Italy, Eudoxus visited Sicily, where he studied medicine with Philiston.
  Around 387 BC, at the age of 23, he traveled with the physician Theomedon, who according to Diogenes Laërtius some believed was his lover, to Athens to study with the followers of Socrates. He eventually became the pupil of Plato, with whom he studied for several months, but due to a disagreement they had a falling out. Eudoxus was quite poor and could only afford an apartment at the Piraeus. To attend Plato's lectures, he walked the seven miles (11 km) each direction, each day. Due to his poverty, his friends raised funds sufficient to send him to Heliopolis, Egypt to pursue his study of astronomy and mathematics. He lived there for 16 months. From Egypt, he then traveled north to Cyzicus, located on the south shore of the Sea of Marmara, the Propontis. He traveled south to the court of Mausolus. During his travels he gathered many students of his own.

  Evgeny Mikhailovich Lifshitz FRS (Russian: Евгений Михайлович Лифшиц; February 21, 1915 – October 29, 1985) was a leading Soviet physicist of Jewish origin and the brother of physicist Ilya Mikhailovich Lifshitz. (Some commonly encountered alternative transliterations of his names include Yevgeny or Evgenii and Lifshits or Lifschitz.) Lifshitz is well known in general relativity for coauthoring the BKL conjecture concerning the nature of a generic curvature singularity. As of 2006^[update], this is widely regarded as one of the most important open problems in the subject of classical gravitation.
  
  With Lev Landau, Lifshitz co-authored Course of Theoretical Physics, an ambitious series of physics textbooks, in which the two aimed to provide a graduate-level introduction to the entire field of physics. These books are still considered invaluable and continue to be widely used.
  Lifshitz was the second of only 43 people ever to pass Landau's "Theoretical Minimum" examination. Landau's wife strongly criticized his scientific abilities, hinting at how much of their joint work was done by Lifshitz and how much by Landau. Despite the sniping, he is well known for many invaluable contributions, in particular to quantum electrodynamics, where he calculated the Casimir force in an arbitrary macroscopic configuration of metals and dielectrics.

He was the first person to propose the theory of the expansion of the Universe, widely misattributed to Edwin Hubble. He was also the first to derive what is now known as the Hubble's law and made the first estimation of what is now called the Hubble constant which he published in 1927, two years before Hubble's article. Lemaître also proposed what became known as the Big Bang theory of the origin of the Universe, which he called his 'hypothesis of the primeval atom'. As he was a secular priest, he was called Abbé, then, after being made a canon, Monseigneur.
  After a classical education at a Jesuit secondary school (Collège du Sacré-Coeur, Charleroi), Lemaître began studying civil engineering at the Catholic University of Leuven at the age of 17. In 1914, he interrupted his studies to serve as an artillery officer in the Belgian army for the duration of World War I. At the end of hostilities, he received the Belgian War Cross with palms.

  Hecataeus of Miletus
  Hecataeus of Miletus (c. 550 BC – c. 476 BC) (Greek Ἑκαταῖος), named after the Greek goddess Hecate, was an early Greek historian of a wealthy family. He flourished during the time of the Persian invasion. After having travelled extensively, he settled in his native city, where he occupied a high position, and devoted his time to the composition of geographical and historical works. When Aristagoras held a council of the leading Ionians at Miletus to organize a revolt against the Persian rule, Hecataeus in vain tried to dissuade his countrymen from the undertaking. In 494 BC, when the defeated Ionians were obliged to sue for terms, he was one of the ambassadors to the Persian satrap Artaphernes, whom he persuaded to restore the constitution of the Ionic cities. Hecataeus is the first known Greek historian, and was one of the first classical writers to mention the Celtic people.
  Some have credited Hecataeus with a work entitled Περίοδος γῆς ("Travels round the Earth" or "World Survey'), written in two books. Each book is organized in the manner of a periplus, a point-to-point coastal survey. One, on Europe, is essentially a periplus of the Mediterranean, describing each region in turn, reaching as far north as Scythia. The other book, on Asia, is arranged similarly to the Periplus of the Erythraean Sea of which a version of the 1st century AD survives. Hecataeus described the countries and inhabitants of the known world, the account of Egypt being particularly comprehensive; the descriptive matter was accompanied by a map, based upon Anaximander’s map of the earth, which he corrected and enlarged. The work only survives in some 374 fragments, by far the majority being quoted in the geographical lexicon Ethnika compiled by Stephanus of Byzantium.

He was of distinguished parentage. Little is known about his early life and education, but he regarded himself as self-taught and a pioneer of wisdom. From the lonely life he led, and still more from the riddling nature of his philosophy and his contempt for humankind in general, he was called "The Obscure" and the "Weeping Philosopher".
  Heraclitus is famous for his insistence on ever-present change in the universe, as stated in the famous saying, "No man ever steps in the same river twice" (see panta rhei, below). He believed in the unity of opposites, stating that "the path up and down are one and the same", all existing entities being characterized by pairs of contrary properties. His cryptic utterance that "all entities come to be in accordance with this Logos" (literally, "word", "reason", or "account") has been the subject of numerous interpretations.

  Immanuel Kant
  Immanuel Kant (German pronunciation: [ɪˈmaːnu̯eːl ˈkant]; 22 April 1724 – 12 February 1804) was a German philosopher from Königsberg (today Kaliningrad of Russia), who researched, lectured, and wrote on philosophy and anthropology during the Enlightenment at the end of the 18th century. At the time, there were major successes and advances in the sciences (for example, Isaac Newton, Carl Friedrich Gauss, and Robert Boyle) applying reason and logic.
  Kant’s major work, the Critique of Pure Reason (Kritik der reinen Vernunft, 1781), aimed to unite reason with experience to move beyond what he took to be failures of traditional philosophy and metaphysics. He hoped to end an age of speculation where objects outside experience were used to support what he saw as futile theories, while opposing the skepticism of thinkers such as Descartes, Berkeley and Hume.
  He stated:
  Kant proposed a ‘Copernican Revolution’ in reverse, saying that:
  Kant published other important works on ethics, religion, law, aesthetics, astronomy, and history. These included the Critique of Practical Reason (Kritik der praktischen Vernunft, 1788) and the Metaphysics of Morals (Die Metaphysik der Sitten, 1797), which dealt with ethics. And the Critique of Judgment (Kritik der Urteilskraft, 1790), which looks at aesthetics and teleology. He aimed to resolve disputes between empirical and rationalist approaches. The former asserted that all knowledge comes through experience; the latter maintained that reason and innate ideas were prior. Kant argued that experience is purely subjective without first being processed by pure reason. He also said that using reason without applying it to experience only leads to theoretical illusions. The free and proper exercise of reason by the individual was both a theme of the Enlightenment, and of Kant's approaches to the various problems of philosophy.

  Sir Isaac Newton PRS MP (25 December 1642 – 20 March 1727 [NS: 4 January 1643 – 31 March 1727]) was an English physicist, mathematician, astronomer, natural philosopher, alchemist, and theologian, who has been "considered by many to be the greatest and most influential scientist who ever lived." His monograph Philosophiæ Naturalis Principia Mathematica, published in 1687, lays the foundations for most of classical mechanics. In this work, Newton described universal gravitation and the three laws of motion, which dominated the scientific view of the physical universe for the next three centuries. Newton showed that the motions of objects on Earth and of celestial bodies are governed by the same set of natural laws, by demonstrating the consistency between Kepler's laws of planetary motion and his theory of gravitation, thus removing the last doubts about heliocentrism and advancing the Scientific Revolution.

A key figure in the 17th century scientific revolution, he is best known for his eponymous laws of planetary motion, codified by later astronomers, based on his works Astronomia nova, Harmonices Mundi, and Epitome of Copernican Astronomy. These works also provided one of the foundations for Isaac Newton's theory of universal gravitation.
  During his career, Kepler was a mathematics teacher at a seminary school in Graz, Austria, where he became an associate of Prince Hans Ulrich von Eggenberg. Later he became an assistant to astronomer Tycho Brahe, and eventually the imperial mathematician to Emperor Rudolf II and his two successors Matthias and Ferdinand II. He was also a mathematics teacher in Linz, Austria, and an adviser to General Wallenstein. Additionally, he did fundamental work in the field of optics, invented an improved version of the refracting telescope (the Keplerian Telescope), and mentioned the telescopic discoveries of his contemporary Galileo Galilei.

  He was posthumously condemned as a heretic by the Orthodox Church in 680-81 because of what was perceived of as a tritheistic interpretation of the Trinity.
  His works were widely printed in Latin translations in Europe from the 15th century onwards. His critique of Aristotle in the Physics commentary was a major influence on Giovanni Pico della Mirandola and Galileo Galilei, who cited Philoponus substantially in his works.
  Possibly born into a Christian family, nothing is known of his early life. Philoponus studied at the school of Alexandria and began publishing from about 510. He was a pupil and sometime amanuensis to the Neoplatonic philosopher Ammonius Hermiae, who had studied at Athens under Proclus.

  Kip Thorne
  Kip Stephen Thorne (born June 1, 1940) is an American theoretical physicist, known for his prolific contributions in gravitation physics and astrophysics and for having trained a generation of scientists. A longtime friend and colleague of Stephen Hawking and Carl Sagan, he was the Feynman Professor of Theoretical Physics at the California Institute of Technology (Caltech) until 2009 and one of the world’s leading experts on the astrophysical implications of Einstein’s general theory of relativity. He continues to do scientific research and is also writing a film.
  Thorne was born in Logan, Utah, the son of Utah State University professors D. Wynne Thorne and Alison C. Thorne, a soil chemist and an economist, respectively. Raised in an academic environment, two of his four siblings are also professors. He became interested in science at the age of eight, after attending a lecture about the solar system. Thorne and his mother then worked out calculations for their own model of the solar system.

  Leucippus
  Leucippus or Leukippos (Greek: Λεύκιππος, first half of 5th century BCE) was one of the earliest Greeks to develop the theory of atomism — the idea that everything is composed entirely of various imperishable, indivisible elements called atoms — which was elaborated in greater detail by his pupil and successor, Democritus.
  According to this atomism, if you take a piece of wood and then cut it in to two equal parts, then do it continuously, eventually you will find a part that you can't cut. This smallest possible part is the "atom". A possible earlier candidate for atomism is Mochus of Sidon, from the Trojan War era (13th or 12th century BCE).
  He was most likely born in Miletus, although Abdera and Elea are also mentioned as possible birth-places.
  Leucippus is a shadowy figure, as his dates are not recorded and he is often mentioned in conjunction with his more well-known pupil Democritus, who replaced indeterminism with determinism as the ontological cause of atomic movement. It is therefore difficult to determine which contributions come from Democritus and which come from Leucippus.

  Lev Landau
  Lev Davidovich Landau (Russian language: Ле́в Дави́дович Ланда́у; January 22 [O.S. January 9] 1908 – April 1, 1968) was a prominent Soviet physicist who made fundamental contributions to many areas of theoretical physics. His accomplishments include the independent co-discovery of the density matrix method in quantum mechanics (alongside John von Neumann), the quantum mechanical theory of diamagnetism, the theory of superfluidity, the theory of second-order phase transitions, the Ginzburg–Landau theory of superconductivity, the theory of Fermi liquid, the explanation of Landau damping in plasma physics, the Landau pole in quantum electrodynamics, and the two-component theory of neutrinos. He received the 1962 Nobel Prize in Physics for his development of a mathematical theory of superfluidity that accounts for the properties of liquid helium II at a temperature below 2.17 K (−270.98 °C).
  Landau was born on January 22, 1908 to Jewish parents in Baku, in what was then the Russian Empire. Landau's father was an engineer with the local oil industry and his mother was a doctor. Recognized very early as a child prodigy in mathematics, Landau was quoted as saying in later life that he scarcely remembered a time when he was not familiar with calculus. Landau graduated at 13 from gymnasium. His parents considered him too young to attend university, so for a year he attended the Baku Economical Technicum. In 1922, at age 14, he matriculated at Baku State University, studying in two departments simultaneously: the department of Physics and Mathematics, and the department of Chemistry. Subsequently he ceased studying chemistry, but remained interested in the field throughout his life.

• Lucio Russo
  Lucio Russo (born 22 November 1944) is an Italian physicist, mathematician and historian of science. Born in Venice, he teaches at the Mathematics Department of the Science College in the University of Rome Tor Vergata.
  In the history of science, he has reconstructed some contributions of the Hellenistic astronomer Hipparchus, through the analysis of his surviving works, reconstructed the proof of heliocentrism attributed by Plutarch to Seleucus of Seleucia and studied the history of theories of tides, from the Hellenistic to modern age.
  In The Forgotten Revolution: How Science Was Born in 300 BC and Why It Had to Be Reborn (Italian: La rivoluzione dimenticata), Russo stresses the well-established fact that Hellenistic science reached heights not achieved by the Classical age science, and proposes that it went further than ordinarily thought. These results were lost with the Roman conquest and during the Middle Ages, because the scholars of that period did not have the capability to understand them. The legacy of Hellenistic science was one of the bases of the scientific revolution of the 16th century, as ancient texts started once again to be available in Europe.

  Lucretius
  Titus Lucretius Carus (ca. 99 BC – ca. 55 BC) was a Roman poet and philosopher. His only known work is the epic philosophical poem De rerum natura about the beliefs of Epicureanism, and which is translated into English as On the Nature of Things or "On the Nature of the Universe".
  Virtually nothing is known about the life of Lucretius. Jerome tells how he was driven mad by a love potion and wrote his poetry between fits of insanity, eventually committing suicide in middle age; but modern scholarship suggests this account was likely an invention. The De rerum natura was a considerable influence on the Augustan poets, particularly Virgil (in his Aeneid and Georgics, and to a lesser extent in his Eclogues) and Horace. It virtually disappeared during the Middle Ages, but was rediscovered in a monastery in Germany in 1417, by Poggio Bracciolini, and played an important role both in the development of atomism (Lucretius was an important influence on Pierre Gassendi) and the efforts of various figures of the Enlightenment era to construct a new Christian humanism.

He was of the Ismaili-, and subsequently Twelver Shī‘ah Islamic belief. The Muslim scholar Ibn Khaldun (1332–1406) considered Tusi to be the greatest of the later Persian scholars.
  Nasir al-Din Tusi was born in the city of Tus in medieval Khorasan (now in north-eastern Iran) in the year 1201 and began his studies at an early age. In Hamadan and Tus he studied the Qur'an, Hadith, Shi'a jurisprudence, logic, philosophy, mathematics, medicine and astronomy.
  He was apparently born into a Shī‘ah family and lost his father at a young age. Fulfilling the wish of his father, the young Muhammad took learning and scholarship very seriously and travelled far and wide to attend the lectures of renowned scholars and acquire the knowledge which guides people to the happiness of the next world. At a young age he moved to Nishapur to study philosophy under Farid al-Din Damad and mathematics under Muhammad Hasib. He met also Farid al-Din al-'Attar, the legendary Sufi master who was later killed by Mongol invaders and attended the lectures of Qutb al-Din al-Misri.

  Nicholas of Cusa
  Nicholas of Kues (1401 – August 11, 1464), also referred to as Nicolaus Cusanus and Nicholas of Cusa, was a cardinal of the Catholic Church from Germany (Holy Roman Empire), a philosopher, theologian, jurist, mathematician, and an astronomer. He is widely considered one of the great geniuses and polymaths of the 15th century. He is today recognized for significant spiritual, scientific and political contributions in European history, notable examples of which include his mystical or spiritual writings on 'learned ignorance' (and mathematical ideas expressed in related essays), as well as his participation in power struggles between Rome and the German states of the Holy Roman Empire.
  Nicholas of Cusa or Kues (Latinized as "Cusa") was the second of four children of Johan Krebs (or Cryfftz) and Katherina Roemer. His father was "a prosperous boat owner and ferryman." He entered the University of Heidelberg in 1416 as "a cleric of the diocese of Trier" studying the liberal arts. He then received his doctorate in Canon law from the University of Padua in 1423. Afterwards, he entered the University of Cologne in 1425 as "a doctor of canon law" which it appears he both taught and practiced there. Following this brief period in Cologne, he became secretary to Otto of Ziegenhain, the Archbishop of Trier, and represented him in Rome in 1427. After the death of Otto, during the period when the archbishopric of Trier was contested by opposing parties, he attended the Council of Basel (1431–49), representing Ulrich von Manderscheid, one of the claimants.

  Nicolaus Copernicus
  Nicolaus Copernicus (German: Nikolaus Kopernikus; Italian: Nicolò Copernico; Polish:  Mikołaj Kopernik (help·info); in his youth, Niclas Koppernigk; 19 February 1473 – 24 May 1543) was a Renaissance astronomer and the first person to formulate a comprehensive heliocentric cosmology which displaced the Earth from the center of the universe.
  Copernicus' epochal book, De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), published just before his death in 1543, is often regarded as the starting point of modern astronomy and the defining epiphany that began the scientific revolution. His heliocentric model, with the Sun at the center of the universe, demonstrated that the observed motions of celestial objects can be explained without putting Earth at rest in the center of the universe. His work stimulated further scientific investigations, becoming a landmark in the history of science that is often referred to as the Copernican Revolution.
  Among the great polymaths of the Renaissance, Copernicus was a mathematician, astronomer, jurist with a doctorate in law, physician, quadrilingual polyglot, classics scholar, translator, artist,Catholic cleric, governor, diplomat and economist.

• Otto E. Neugebauer
  Otto Eduard Neugebauer (May 26, 1899 – February 19, 1990) was an Austrian-American mathematician and historian of science who became known for his research on the history of astronomy and the other exact sciences in antiquity and into the Middle Ages. By studying clay tablets, he discovered that the ancient Babylonians knew much more about mathematics and astronomy than had been previously realized. The National Academy of Sciences has called Neugebauer "the most original and productive scholar of the history of the exact sciences, perhaps of the history of science, of our age."
  Neugebauer began as a mathematician, turned first to Egyptian and Babylonian mathematics, and then took up the history of mathematical astronomy. In a career of sixty-five years, he largely created our current understanding of mathematical astronomy from Babylon and Egypt, through Greco-Roman antiquity, to India, Islam, and Europe of the Middle Ages and Renaissance. His influence on the study of the history of the exact sciences is profound.

  Parmenides
  Parmenides of Elea ( /pɑrˈmɛnɨdiːz əv ˈɛliə/; Ancient Greek: Παρμενίδης ὁ Ἐλεάτης; fl. early 5th century BC) was an ancient Greek philosopher born in Elea, a Greek city on the southern coast of Italy. He was the founder of the Eleatic school of philosophy. The single known work of Parmenides is a poem, On Nature, which has survived only in fragmentary form. In this poem, Parmenides describes two views of reality. In "the way of truth" (a part of the poem), he explains how reality (coined as "what-is") is one, change is impossible, and existence is timeless, uniform, necessary, and unchanging. In "the way of opinion," he explains the world of appearances, in which one's sensory faculties lead to conceptions which are false and deceitful. These ideas strongly influenced the whole of Western philosophy, perhaps most notably through its effect on Plato.

  Plato
  Plato ( /ˈpleɪtoʊ/; Greek: Πλάτων, Plátōn, "broad"; 424/423 BC – 348/347 BC) was a Classical Greek philosopher, mathematician, student of Socrates, writer of philosophical dialogues, and founder of the Academy in Athens, the first institution of higher learning in the Western world. Along with his mentor, Socrates, and his student, Aristotle, Plato helped to lay the foundations of Western philosophy and science. In the words of A. N. Whitehead:
  The safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato. I do not mean the systematic scheme of thought which scholars have doubtfully extracted from his writings. I allude to the wealth of general ideas scattered through them.
  Plato's sophistication as a writer is evident in his Socratic dialogues; thirty-six dialogues and thirteen letters have been ascribed to him. Plato's writings have been published in several fashions; this has led to several conventions regarding the naming and referencing of Plato's texts. Plato's dialogues have been used to teach a range of subjects, including philosophy, logic, ethics, rhetoric, and mathematics.

  Plutarch
  
  Plutarch (English pronunciation: /'pluːtɑːk/; Greek: Πλούταρχος, Ploútarkhos, Koine Greek: [plŭːtarkʰos]) then named, on his becoming a Roman citizen, Lucius Mestrius Plutarchus (Μέστριος Πλούταρχος),c. 46 – 120 AD, was a Greek historian, biographer, essayist, and Middle Platonist known primarily for his Parallel Lives and Moralia. He was born to a prominent family in Chaeronea, Boeotia, a town about twenty miles east of Delphi.
  Plutarch was born in 46 AD in the small town of Chaeronea, in the Greek region known as Boeotia. His family was wealthy. The name of Plutarch's father has not been preserved, but it was probably Nikarchus (Greek: Nίκαρχoς), from the common habit of Greek families to repeat a name in alternate generations. The name of Plutarch's grandfather was Lamprias, as he attested in Moralia and in his Life of Antony.
  His brothers, Timon and Lamprias, are frequently mentioned in his essays and dialogues, where Timon is spoken of in the most affectionate terms. Rualdus, in his 1624 work Life of Plutarchus, recovered the name of Plutarch's wife, Timoxena, from internal evidence afforded by his writings. A letter is still extant, addressed by Plutarch to his wife, bidding her not give way to excessive grief at the death of their two year old daughter, who was named Timoxena after her mother. Interestingly, he hinted at a belief in reincarnation in that letter of consolation.

  Ptolemy
  Claudius Ptolemy ( /ˈtɒləmi/; Greek: Κλαύδιος Πτολεμαῖος, Klaudios Ptolemaios; Latin: Claudius Ptolemaeus; c. AD 90 – c. AD 168), was a Greek-Roman citizen of Egypt who wrote in Greek. He was a mathematician, astronomer, geographer, astrologer, and poet of a single epigram in the Greek Anthology. He lived in Egypt under Roman rule, and is believed to have been born in the town of Ptolemais Hermiou in the Thebaid. This theory, proposed by Theodore Meliteniotes, could be correct, but it is late (ca. 1360) and unsupported. There is no reason to suppose that he ever lived anywhere else than Alexandria, where he died around AD 168.
  Ptolemy was the author of several scientific treatises, at least three of which were of continuing importance to later Islamic and European science. The first is the astronomical treatise now known as the Almagest (in Greek, Ἡ Μεγάλη Σύνταξις, "The Great Treatise", originally Μαθηματικὴ Σύνταξις, "Mathematical Treatise"). The second is the Geography, which is a thorough discussion of the geographic knowledge of the Greco-Roman world. The third is the astrological treatise known sometimes in Greek as the Apotelesmatika (Ἀποτελεσματικά), more commonly in Greek as the Tetrabiblos (Τετράβιβλος "Four books"), and in Latin as the Quadripartitum (or four books) in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day.

Most of the information about Pythagoras was written down centuries after he lived, so very little reliable information is known about him. He was born on the island of Samos, and might have travelled widely in his youth, visiting Egypt and other places seeking knowledge. Around 530 BC, he moved to Croton, a Greek colony in southern Italy, and there set up a religious sect. His followers pursued the religious rites and practices developed by Pythagoras, and studied his philosophical theories. The society took an active role in the politics of Croton, but this eventually led to their downfall. The Pythagorean meeting-places were burned, and Pythagoras was forced to flee the city. He is said to have ended his days in Metapontum.

• Robert H. Dicke
  Robert Henry Dicke (May 6, 1916 – March 4, 1997) was an American physicist who made important contributions to the fields of astrophysics, atomic physics, cosmology and gravity.^{[citation needed]}
  Born in St. Louis, Missouri, Dicke completed his bachelor's degree at Princeton University and his doctorate, in 1939, from the University of Rochester in nuclear physics. During the Second World War he worked in the Radiation Laboratory at the Massachusetts Institute of Technology where he worked on the development of radar and designed the Dicke radiometer, a microwave receiver. He used this to set a limit on the temperature of the microwave background radiation, from the roof of the Radiation Laboratory, of less than 20 kelvins.
  In 1946, he returned to Princeton University, where he remained for the rest of his career. He did some work in atomic physics, particularly on the laser and measuring the gyromagnetic ratio of the electron. An important contribution to the field of Spectroscopy and Radiative Transfer was his prediction of the phenomenon called Dicke narrowing (aka collisional narrowing): When the mean free path of an atom is much smaller than the wavelength of one of its radiation transitions, the atom changes velocity and direction many times during the emission or absorption of a photon. This causes an averaging over different Doppler states and results in an atomic linewidth that is much narrower than the Doppler width. Dicke narrowing occurs at relatively low pressures in the millimeter wave and microwave regions (where it is used in atomic clocks to improve precision). Dicke narrowing is analogous to the Mössbauer effect for gamma rays.

  Seleucus (or Seleukos) of Seleucia (born c. 190 BC, fl. 150s BC) was a Hellenistic astronomer and philosopher. Coming from Seleucia on the Tigris, the capital of the Seleucid empire, or, alternatively, Seleukia on the Red Sea, he is best known as a proponent of heliocentrism and for his theory of the origin of tides.
  Teaching around 150 BC, he is known to have been a follower of the heliocentric theory of Aristarchus of Samos, which stated that the Earth rotated around its own axis which in turn revolved around the Sun. According to Plutarch, Seleucus was the first to demonstrate the heliocentric system through reasoning, but it is not known what arguments he used. According to Bartel Leendert van der Waerden, Seleucus may have constructed his heliocentric theory by determining the constants of a geometric model and by developing methods to compute planetary positions using this model, as Nicolaus Copernicus later did in the 16th century. He may have used trigonometric methods that were available in his time, as he was a contemporary of Hipparchus.

  Strabo
  Strabo,,^{[pronunciation?]}, also written Strabon (Greek: Στράβων; 64/63 BC – ca. AD 24), was a Greek geographer, philosopher and historian.
  Strabo was born to an affluent family from Amaseia in Pontus (modern Amasya, Turkey), a city that he said was situated the approximate equivalent of 75 km from the Black Sea. His mother was Georgian. Pontus had recently fallen to the Roman Republic, and although politically he was a proponent of Roman imperialism, Strabo belonged on his mother's side to a prominent family whose members had held important positions under the resisting regime of King Mithridates VI of Pontus.
  Strabo's life was characterized by extensive travels. He journeyed to Egypt and Kush, as far west as coastal Tuscany and as far south as Ethiopia in addition to his travels in Asia Minor and time spent in Rome. Travel throughout the Mediterranean and Near East, especially for scholarly purposes, was popular during this era and was facilitated by the relative peace enjoyed throughout the reign of Augustus (27 BC – AD 14). He moved to Rome in 44 BC, and stayed there, studying and writing, until at least 31 BC. In 29 BC, on his way to Corinth (where Augustus was at the time), he visited the island of Gyaros in the Aegean Sea. Around 25 BC, he sailed up the Nile until reaching Philae, after which point there is little record of his proceedings until 17 AD.

Many, most notably Aristotle, regard him as the first philosopher in the Greek tradition. According to Bertrand Russell, "Western philosophy begins with Thales." Thales attempted to explain natural phenomena without reference to mythology and was tremendously influential in this respect. Almost all of the other pre-Socratic philosophers follow him in attempting to provide an explanation of ultimate substance, change, and the existence of the world—without reference to mythology. Those philosophers were also influential, and eventually Thales' rejection of mythological explanations became an essential idea for the scientific revolution. He was also the first to define general principles and set forth hypotheses, and as a result has been dubbed the "Father of Science", though it is argued that Democritus is actually more deserving of this title.

  Tycho Brahe
  Tycho Brahe (14 December 1546 – 24 October 1601), born Tyge Ottesen Brahe, was a Danish nobleman known for his accurate and comprehensive astronomical and planetary observations. Coming from Scania, then part of Denmark, now part of modern-day Sweden, Tycho was well known in his lifetime as an astronomer and alchemist.
  In his De nova stella (On the new star) of 1573, he refuted the Aristotelian belief in an unchanging celestial realm. His precise measurements indicated that "new stars" (novae or also now known as supernovae), in particular that of 1572, lacked the parallax expected in sub-lunar phenomena, and were therefore not "atmospheric" tail-less comets as previously believed, but occurred above the atmosphere and moon. Using similar measurements he showed that comets were also not atmospheric phenomena, as previously thought, and must pass through the supposed "immutable" celestial spheres.
  Tycho Brahe was granted an estate on the island of Hven and the funding to build the Uraniborg, an early research institute, where he built large astronomical instruments and took many careful measurements, and later Stjerneborg, underground, when he discovered that his instruments in the former were not sufficiently steady. Something of an autocrat on the island he nevertheless founded manufactories such as paper-making to provide material for printing his results. After disagreements with the new Danish king in 1597, he was invited by the Bohemian king and Holy Roman emperor Rudolph II to Prague, where he became the official imperial astronomer. He built the new observatory at Benátky nad Jizerou. Here, from 1600 until his death in 1601, he was assisted by Johannes Kepler. Kepler later used Tycho's astronomical results to develop his own theories of astronomy.

  Udayana also known as 'Udayanācārya' (Udyanacharya, or "Master Udayana) lived in the 10th century, in Kariyan village in Mithila, near present day Darbhanga, Bihar state, India. Udayana was a very important Hindu logician who attempted to reconcile the views held by the two major schools of logic (Nyaya and Vaisheshika). This became the root of the Navya-Nyāya school of the 13th century, established by Gangesha Upadhyaya (“New Nyāya”) school of “right” reasoning, which is still recognized and followed in some regions of India.
  Udayana wrote a sub-gloss on Vachaspati's work called the Nyaya-vaartika-taatparya-tiikaa-parishuddhi. He wrote several other works such as the Kusumanjali, Atma-tattva-viveka, Kiranaavali and Nyaya-parishishhta (also called Bodha siddhi or Bodha shuddhi).

• Vera Rubin
  Vera (Cooper) Rubin (born (1928-07-23) July 23, 1928 (age 83)) is an American astronomer. She pioneered work on galaxy rotation rates. She is famous for uncovering the discrepancy between the predicted angular motion of galaxies and the observed motion, by studying galactic rotation curves. This phenomenon became known as the galaxy rotation problem.
  Vera Rubin can be seen on the BBC documentary Most of Our Universe is Missing.
  Currently, the theory of dark matter is the most popular candidate for explaining the galaxy rotation problem. The alternative theory of MOND (Modified Newtonian Dynamics) has little support in the community. Rubin, however, supports the MOND approach, stating "If I could have my pick, I would like to learn that Newton's laws must be modified in order to correctly describe gravitational interactions at large distances. That's more appealing than a universe filled with a new kind of sub-nuclear particle."
  After she had earned an A.B. from Vassar College (1948), she tried to enroll at Princeton but never received their graduate catalog as women there were not allowed in the graduate astronomy program until 1975. She applied to Cornell University, where she studied physics under Philip Morrison, Richard Feynman, and Hans Bethe. There she earned an M.A. in 1951. Then in 1954 at Georgetown University she earned a Ph.D.

  Vācaspati was a Maithili Brahmin who lived near the frontier between India and Nepal (what is now Vachaspati Nagar (Andhra Thardhi), Madhubani). The details of his life have been lost, though he is said to have named one of his works after his wife, Bhāmatī. He wrote commentaries on the main works of all the major Hindu schools of thought at the time, as well as one non-commentary, Tattvabindu.
  In Tattvabindu, Vācaspati examines four competing theories of linguistic meaning:
  After examining each of these theories, Vācaspati presents his own theory, abhihitānvayavāda, according to which understanding of the meaning of a whole sentence is reached by inferring it, in a separate act of lakṣanā or implication, from the individual meanings of the constituent words.

  Will Durant
  William James Durant (November 5, 1885 – November 7, 1981) was a prolific American writer, historian, and philosopher. He is best known for The Story of Civilization, 11 volumes written in collaboration with his wife Ariel Durant and published between 1935 and 1975. He was earlier noted for The Story of Philosophy, written in 1926, which one observer described as "a groundbreaking work that helped to popularize philosophy."
  He conceived of philosophy as total perspective, or, seeing things "sub specie totius," a phrase inspired by Spinoza's "sub specie aeternitatis." He sought to unify and humanize the great body of historical knowledge, which had grown too voluminous and become fragmented into esoteric specialties, and to vitalize it for contemporary application. Durant was a gifted prose stylist and storyteller who won a large readership in great part because of the nature and excellence of his writing, which, in contrast to formal academic language, is lively, witty, charismatic, colourful, ornate, epigrammatic, in short, "humanized." Max Schuster, co-founder of the publisher Simon & Schuster (which also published Durant's works), and himself an admirer of Durant's writings for their beauty, remarked that Durant's prose "begs to be read aloud."John Little, who founded and heads the Will Durant foundation and has devoted much effort towards popularizing Durant's works in the 21st century, echoes Schuster's admiration for Durant's works in words which Durant himself sometimes used to describe a few of the finest works of Classical Antiquity: "prose so beautiful it rivals poetry."

  Wolfgang Rindler
  Wolfgang Rindler (born 18 May 1924, Vienna) is a leading physicist working in the field of General Relativity where he is well known for introducing the term "event horizon", Rindler coordinates, and (in collaboration with Roger Penrose) for popularizing the use of spinors in general relativity. He is also a prolific textbook author.
  Rindler was the son of a lawyer. Because of his Jewish ancestry, he fled before the Nazis to England in the course of the so called Kindertransport in 1938. Rindler gained his B.Sc. and M.Sc. from Liverpool University and his Ph.D. from Imperial College London. In 1956 he was at the Cornell University and starting with 1963 at the new founded Southwest Center for Advanced Studies, later called University of Texas at Dallas, where he is still (2012) professor. He was visiting scholar at King's College London (1961/62), at the University La Sapienza in Rome (1968/69), at the University of Vienna (1975, 1987), at the Cambridge University (Churchill College, 1990).

  Yakov Zel'dovich
  Yakov Borisovich Zel'dovich FRS (Belarusian: Якаў Барысавіч Зяльдовіч, Russian: Я́ков Бори́сович Зельдо́вич) (8 March 1914 – 2 December 1987) was a prolific Soviet physicist born in Belarus. He played an important role in the development of Soviet nuclear and thermonuclear weapons, and made important contributions to the fields of adsorption and catalysis, shock waves, nuclear physics, particle physics, astrophysics, physical cosmology, and general relativity.
  He was born Jewish in Minsk (now Belarus). Four months later his family moved to Saint Petersburg. They remained in that city (known as Leningrad from 1924–1991) until August 1941, when together with the institute where Zel'dovich worked, they were evacuated to Kazan to avoid the Axis Invasion of the Soviet Union. They remained in Kazan until the summer of 1943, when Zel'dovich moved to Moscow. In May 1931, at age seventeen, Zel'dovich became a laboratory assistant at the Institute of Chemical Physics of the USSR Academy of Sciences. He was associated with the Institute until the end of his life. In 1936 he defended his dissertation, which was on the adsorption and catalysis on heterogeneous surfaces, for his Candidate of Science (equal to PhD). The most important point of it was the research on the Freundlich (or classical) adsorption isotherm. Zel'dovich discovered the theoretical foundation of this empirical observation. In 1939 he received the degree of Doctor of Science (Physics and Mathematics), the doctor dissertation being on the oxidation of nitrogen. Zel'dovich discovered its mechanism, known in physical chemistry as Thermal NO Mechanism or Zel'dovich Mechanism.

  Zeno of Elea
  Zeno of Elea ( /ˈziːnoʊ əv ˈɛliə/; Greek: Ζήνων ὁ Ἐλεάτης; ca. 490 BC – ca. 430 BC) was a pre-Socratic Greek philosopher of southern Italy and a member of the Eleatic School founded by Parmenides. Aristotle called him the inventor of the dialectic. He is best known for his paradoxes, which Bertrand Russell has described as "immeasurably subtle and profound".
  Little is known for certain about Zeno's life. Although written nearly a century after Zeno's death, the primary source of biographical information about Zeno is Plato's Parmenides dialogue. In the dialogue, Plato describes a visit to Athens by Zeno and Parmenides, at a time when Parmenides is "about 65," Zeno is "nearly 40" and Socrates is "a very young man". Assuming an age for Socrates of around 20, and taking the date of Socrates' birth as 469 BC gives an approximate date of birth for Zeno of 490 BC. Plato says that Zeno was "tall and fair to look upon" and was "in the days of his youth … reported to have been beloved by Parmenides".

• Étienne Tempier
  Étienne (Stephen) Tempier (also known as Stephanus of Orleans) (died 3 September 1279) was a French bishop of Paris during the 13th century. He was Chancellor of the Sorbonne from 1263 and bishop of Paris from 1268.
  He is best remembered for promulgating a Condemnation of 219 philosophical and theological propositions (or articles) that addressed ideas and concepts that were being discussed and disputed in the faculty of Arts at the University of Paris.
  Born in Orléans, Tempier studied in Paris, where he became master of theology and canon of Notre Dame. During a period of about five years (1263–ca. 1268), Tempier was the Chancellor of the chapter of Notre Dame at Paris, succeeding Erich von Veire. At that time, the Chancellor of the Chapter was also the Chancellor of the University of Paris.
  He served as bishop of Paris from 7 October 1268 until his death on 3 September 1279. Temper had been a master in the faculty of theology.
  In 1270 Tempier, encouraged by Henry of Ghent (died 1293), had issued a formal condemnation of thirteen doctrines held by "radical Aristotelians." These included the unity of intellect, causal necessity, and the eternity of the world. The investigation into errors then prevalent at the Parisian university was prompted by the Portuguese cleric Juliani, who was later elected Pope John XXI. A former professor of theology at the University of Paris, he wrote Tempier on January 28, 1277. The pope told Tempier that he had heard reports of heretical opinions in the Paris area, and requested to be informed of the situation. By this time Tempier was already investigating heretical opinions at the University of Paris.
