BioBlitz or bioblitz

a snapshot of the living species of a given natural area which allows the scientific community to learn more about biodiversity richness and health

Ancient Greece (古代ギリシア)

→ forming the foundation of western philosophy, science and ethic

↔ ideological philosophy that places emphasis on idea (sensu Plato) that is as non-materialist eidos

Ionian/Milesian School (イオニア学派)

patriarch of western philosophy (Milesian)
the father of Greek mathematics
Seven Sages of Greece

Ex. measured the height of pyramids

doxastic that the water is the arche (universal principle on all of the nature, 動力因)

The 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
evolutionary view of living things → primitive organisms emerged from mad and human originating from fish-like organisms

everything flows → all things come into being by conflict of opposites

Ex. soul = the mixture of fire and water

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
S ∝ r²
the area of circle (S) is proportional to the square of raidus (r)

Summarizing Ionian philosophy: all things existed in this mass, but in a confused and indistinguishable form

Eleatic (エレア学派)

the spherical land, earth and universe with antipodes → sphere is the most perfect solid
→ celestial motion (天体運動) → circular motion
all things are numbers (万物は数である)

→ systematization of numbers Ex. prime number

having an overtone of religious meanings

the forms are more important than the components to explain the structures of matter
→ the soul is the most important → body = the grave of soul

difficulties in finding out discoverers becasue of the esoterica
Ex. the Pythagorean (ピタゴラスの定理)

it was known about 1000 years before the report
Pythagorean triples: c² = a² + b² → a, b and c exist

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

On 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

• Pythagoras and Parmenides established the foundation of ideology that characterized the late Greek philosophy

paradox of the runner (走者の逆理)

materialistic interpretation = the facts (of life) are permanent

→ the everlastingness is formed accidentally by binding the four elements (arche): water, earth, air and fire

origin of life = abiogenesis (自然発生説)
observation of the volcano Etna → the inside of earth consists of melted substances

atomism: the diverse morphology of substances is determined by the sizes and/or arrangements of atoms that are the composition elements of substances
materialism is daily applied

philosophy of Sophists, including Protagoras, active in BC5 c were influenced greatly by the atomism

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)

patriarch of medical science → medical treatments proposed by observations and experiences → ethic of medical doctor (bioethics)
human body consists of four types of fluids (black bile, blood, yellow bile and mucus) → disease when they are unbalanced

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
soul - most important for human

→ transgression (culpa) = ignorance (darkness)

Socratic irony: the dissimulation of ignorance as a means of confuting an adversary
I know that I know nothing

solving doubling the cube (立方体倍積問題)

Athenai (アテナイ)

Greek - lost the political power

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
idea: the material world as it seems to us is not the real world, but only an "image" or "copy" of the real world
the apparent world of forms (constantly changes) ↔ an unchanging and unseen world (probably the cause of what is apparent)

Plato's tripartite theory of soul

psyche = logical (logistykon) + spirited (thymoeides) + appetitive (epithymetikon)

The Academy (Platonism, プラトン学派)

proven that only five types of regular bodies are present

proportion, sectional mensuration (区分求積法)
Eudoxan planetary models: mathematical interpretation of planetary motion

pupil of Plato, pedagogue of the Great Alexander
Historia Animalium

→ The birth of 3-4 shcools that are materialism and individualistic

The schools of Greek philosophy (ギリシア哲学学派)

"Historia Plantarum", "De cauris plantarum"(「石について」)

hypothesis that the center of the world is sun = heliocentricism (地動説)

principle of Archimedes (= principle of buoyancy)

"On the Elements According to Hippocrates"

"Liber Abaci": introduced Indian-Arabic mathematics, numeration, calculation, etc.

experimental sicence (sprout of modern science)

1/1² + 1/2² + 1/3² + … → convergence

mathematics and physics

1831: complex number

1543 a model of the universe - the Sun rather than the Earth at the center of the universe (地動説)

developed independently from Aristarchus of Samos (c. 310-c.230BC)

1584 cosmic pluralism: stars are distant suns surrounded by their own planets, infinite universe

1895 Discovered X-ray: the unit (roentgen) of X-ray, γ-ray is derived from his name

1896 discovered the radioactivity of uranium (U)
the start point was the rejected hypothesis of the essence of X-ray

Fahter of Alexandre Edmond Becquerel（1820-1891)

the unit of radioactivity, curie (Ci), is from Mr. and Mrs. Curie

1897 cathode rays (陰極線) = flow of electron (電子) emerged from the atom

Rutherford scattering (ラザフォード散乱) = repulsion force (反発力)
1899 radioactive ray emerged from radioactive element (放射性元素) = three types: α, β, γ-rays

α-ray (alpha ray, α線): +charge = ⁴He (alpha particle, α-粒子)

(Seerri 2011)

Periodic table (周期表)

list of 33 elements

atomic weights seemed to be multiples of that of hydrogen (H)

tried to formulate one of the earliest attempts to classify the elements
1829 triads (三組元素): some of the elements into groups of three, with the members of each group having related properties

Li-Na-K, Cl-Br-I, Ca-Sr-Ba, S-Se-Te

embryo stage of atomic hypothesis and molecule hypothesis

the elements, when ordered by their atomic weights, displayed similar properties at regular intervals

the law of octaves: divided the then discovered 56 elements into 11 groups, based on the characteristics

the proportional numbers of the elements

independently published
63 elements were already-known →
the seats of unknown elements were blank - the properties were predicted

argon (Ar) (noble gas or rare gas, 希ガス) was discovered
→ revision of periodic table

An element with an even atomic number (e.g., C = 6) is more abundant than both elements with the adjacently larger and smaller odd atomic numbers (B = 5 and N = 7)

Isotope (同位体)

Stable isotope (安定同位体)

Isotopologue (同位体分子種)

Element = Σisotopologue (abundance, %): δ range in ‰
H = ¹H (99.9844) + ²H (D) (0.0156): D/H = 700
O = ¹⁶O (99.763) + ¹⁷O (0.0375) + ¹⁸O (0.1995): ¹⁸O/¹⁶O = 100
C = ¹²C (98.89) + ¹³C (1.11): ¹³C/¹²C = 100
N = ¹⁴N (99.64) + ¹⁵N (0.36): ¹⁵N/¹⁴N = 50
S = ³²S (95.02) + ³³S (0.75) + ³⁴S (4.21) + ³⁶S (0.02): ³⁴S/³²S = 100

they generally have equal chemical properties
their mass differences confer different physical properties

heavier isotopic molecules have

lower mobility
stronger binding energy
fewer collisions
lower diffusion energy

⇒ application to biogeochemical cycle

1. a science of environment = environmental science: need independent field of research → study on restoration of the rights of human life (Igeta 1981)
2. sciences of environment - environmental sciences
   need interdisciplinary collaboration → not to confuse environmental sciences with environmental issues → need environmental science

need to cooperate with field experiments and lab-experiments
nowadays, experimental science is one of the popular scientific approaches.

method: principles of mechanical reductionism vs wholism

in environmental science, wholism is major because the study deals with significance or fatal problems on human and other living things, i.e., the total phenomena of studies in fields.

1. 3E: earth science - ecology - economy
2. studies on the type of problem finding
3. 3A approach: assessment science, action science, appropriate science → global mind and local action

Global warming (地球温暖化)

Ultraviolet (ozone hole)

実証主義positivism ≈ justificationism (正当化主義)

Method (方法)

the law of uniformity of nature

nature behaves in the same way under same conditions

the law of causation

every event has a cause
