Natural scienceA branch of science concerned with the description, prediction, and understanding of natural phenomena → natural philosophy
biology (or biological science) Citizen science, CS (市民科学)= community science, crowd science, crowd-sourced science, civic science and volunteer monitoringDef. scientific research conducted, in whole or in part, by nonprofessional and/or amateur scientists European Commission. 2013. Green Paper on Citizen Science |
BioBlitz or bioblitzcounting species through citizen sciencea snapshot of the living species of a given natural area which allows the scientific community to learn more about biodiversity richness and health |
Primitive society (原始社会) or primeval time (太古)science = field biology to surviveCosmic viewBC 6000 Mesopotamia (Babylonia)astronomy = astrology → constellation (BC 3000) BC 8c: 36 asterisms drawn on clay tablets
combine decimal and sexagesimal: 1 year = 360 days → circumference |
Ancient Greece (古代ギリシア)BC600- meridian of ancient Greek civilization→ forming the foundation of western philosophy, science and ethic tried to explain the world in terms of natural sciences that place emphasis on materialist philosophy → history of natural sciences↔ ideological philosophy that places emphasis on idea (sensu Plato) that is as non-materialist eidos Ionian/Milesian School (イオニア学派)Thales of Miletus (BC624?-546): merchant (chapman)/pre-Socratic Greek philosopher and mathematician
patriarch of western philosophy (Milesian) Ex. measured the height of pyramids doxastic that the water is the arche (universal principle on all of the nature, 動力因) Anaximandros (Eng. Anaximander, BC c. 610-BC546): pupil of ThalesThe apeiron (= indefinite, infinite, boundless or unlimited) is the arche (= eternal and ageless) diverse substances are born from the metamorphosis of aperion
the Earth = cylindrical form Helakleitos (Eng. Heraclitus, BC c. 535- BC c. 470/475): fire is the arche everything flows → all things come into being by conflict of opposites Ex. soul = the mixture of fire and water Anaxagoras (BC c. 500- c. 428)Cosmic mind (Nous, ≈ mind ヌース/理性): arranging all other things in the cosmos in their proper order, started them in a rotating motion, and controlling them somehow, having a strong connection with living things
all substances can be divided infinitely into atoms Summarizing Ionian philosophy: all things existed in this mass, but in a confused and indistinguishable form BC480 Battle of SalamisEleatic (エレア学派)differences between the thoughts of ideology and materialism became clearlyPythagoras of Samos (BC582-493/497, aged around 75), southern Italy
the spherical land, earth and universe with antipodes → sphere is the most perfect solid → systematization of numbers Ex. prime number → Pythagorean (ピタゴラス学派)having an overtone of religious meanings
the forms are more important than the components to explain the structures of matter
difficulties in finding out discoverers becasue of the esoterica
it was known about 1000 years before the report Ex. proved that there are only five regular solids, n = 4 (regular tetrahedron), 6 (regular hexahedron), 8 (regular octahedron), 12 (regular dodecahedron), and 20 (regular icosahedron) regular polygons exist ad infinitum Parmenides of Elea (BC500/475-?): founded Eleatic schoolOn nature (a poem): Thought and being are the same
the movements and substances are likely to be seen as an existence → founder of metaphysics or ontology
paradox of Zenon (ゼノンの逆理) Leukippos (date of birth and death unknown, active in BC440-BC430)Demokritos (Eng.Democritus, BC c. 460-370?): the peak of materialism
atomism: the diverse morphology of substances is determined by the sizes and/or arrangements of atoms that are the composition elements of substances philosophy of Sophists, including Protagoras, active in BC5 c were influenced greatly by the atomism |
Epikouros (Eng. Epicurus, BC341-BC270)
Hedonism (快楽主義): the only thing that is intrinsically valuable is one's own pleasure pleasure must be persistent the basic constituents are atoms - uncuttable bits of matter Protagoras (BC c. 490-BC c. 420)Sophist as teacher for hire, Man is the measure of all things = there is no absolute truth, but that which individuals deem to be the truth → the purpose of life is material success rather than truth (veritas) Hippokrates (BC460?-370?): doctor in the ancient Greek
patriarch of medical science → medical treatments proposed by observations and experiences → ethic of medical doctor (bioethics) the thought is a contrast to the thought of sophist Greek philosophy was the peak under him
Socratic method (elenchus): a negative method of hypothesis elimination, in that better hypotheses are found by steadily identifying and eliminating those that lead to contradictions → transgression (culpa) = ignorance (darkness)
Socratic irony: the dissimulation of ignorance as a means of confuting an adversary solving doubling the cube (立方体倍積問題) Theodoros (BC410?-): mathmathics professor of PlatonAthenai (アテナイ)BC431-404: the Peloponnesian warGreek - lost the political power Platon (Eng. Plato, BC427-BC347): Timaeus (on the nature)theory of forms or theory of ideas (イデア論) - systemized Socratic idealism understanding idea and teach the knowledge obtained by idea
virtus (virtue, 善): something spiritual beyond all the feeling Arkithas (Eng. Archytas, BC428-BC347) Theaitetos (BC415-369): math. proven that only five types of regular bodies are present Eudoxos (BC409-355), astronomer, mathematician proportion, sectional mensuration (区分求積法) Eudoxan planetary models: mathematical interpretation of planetary motion Aristoteles (Aristotle, Aristote, アリストテレス, BC384-BC322) pupil of Plato, pedagogue of the Great Alexander Historia Animalium Organon (Organum) - collective designation of logic described by Aristoteles, including: Categoriae, De Interpretatione, Analytica Priora, Analytica Posteriora, Topica and De Sophisticis Elenchis Menaichmos (BC350?-): conoidThe birth of 3-4 schools that are materialism and individualisticThe schools of Greek philosophy (ギリシア哲学学派) Eudemos (BC320?-): geometryTheophrates (BC372-287/288) "Historia Plantarum", "De cauris plantarum"(「石について」) Aristarchus of Samos (BC 310?-230?)280? the center of the world is sun = heliocentricism (地動説) Euclid, or Eukleides (BC300-?): Euclidean geometryArchimedes (BC287-212) principle of Archimedes (= principle of buoyancy) Apollonios Pergaeus (BC260-200?) Eratosteres (BC275-194, or BC237-197, or 236-194) Hipparchos BC150? Heron BC100? Menelaus BC100? Galenos 129-199 or 131-201: Greek physician, surgeon and philosopher "On the Elements According to Hippocrates" |
