AXIOMS AND THEOREMS

Axioms-is a preposition that is not proved or demonstrated but consider self-evident or subject to necessary decision.
Theorems-is a atatement which has been proven or has been established its validity.

Historical Background
The early Greeks dev. the logico deductive method where by conclusions( new knowledge) follow from premises(old knowledge)

Euclid established common notions
(very basic, self evident assertions)

1.Things which are equal to the same thing are also equal to one another.
2.If equals be added to equals, the wholes are equal.
3.If equals be subtracted from equals, the remainers are equals.
4.Things which coincide with one another are equal to one another.
5.The whole is greater than a part.


AXIOMATIC SYSTEM
-is any set axiom from which some or all axioms can be used in conjuction to logically derive theorems.

CHARACTERISTIC
Independent-derived from other axioms in the system.
Complete-if for every statement either itself or its negation is derivable.
Consistent-if it has contradiction.

ASTRONOMY

-it is the study of celestial bodies or objects such as stars, planets, comets, and galaxies and its phenomena.
-Greek word"astrom"-stars
-homos-law


During the 20th Century, astronomy split into two major categories.

PHYSICS TECHNOLOGY



A. Observational Astronomy
-focused in acquiring data from observation which then analyzed by the aids of basis of basic principles of Physics.

B.Theoretical Astronomy
-oriented towards the development computer or analytical models to described astronomical objects and phenomena.

Some Contribution of Early Civilization

Babylonians
-beggining of mathematical and scientific astronomy. They discovered the lunar eclipse recorded in repeating cycle known as "caros".

Greeks (3rd BC)

ISLAMIC SCIENCE

Islamic culture is the most relevant to European Science.

GREEK-ARABIC-LATIN-HEBREW

The Arabic culture and language spread afar: to Portugal in the west and to the frontiers of China in the East and over many degrees of latitude.The most characteristic Arabic Scientific developments were in:

Alchemy
-Medieval chemical art whose principles objectives where to find the panacea and to transmute base metals into gold.

Rhazes
-Makes the earliest known suggestions for furnishing a chemical laboratory.

Math
Arabic numerals - an Indian system of numerical notation during the 19th century.

It was invented in India passed through Persian to the Arabs, and was introduced in the Europe in the 10th century.
Persian Mohammed IBN Alkhwarismi is the Persian Mohammed

-He developed the process of vectification.

ASTRONOMY AND ASTROLOGY
Constant preoccupation in the Islamic world. It was developed in Spain.
Cordova- located in Southern Spain.
Toledo- located in Central Spain.
Toledan- tables of proposition were drawn up in 1080.

INDIAN SCIENCE

The Indian Civilization is about the oldest still alive, and it achieved the high level of technology at an early stage.

The history of science and technology in India begins with the prehistoric human activity in Mehrgarh or Pakistan and continues through the Indus Valley Civilization also known as the Bronze Age Civilization to the early state and empires.

The Science And Technology in India has something to do with the following field:
Agriculture
Indian Astrology
Zinc Metallurgy
Mathematics

AGRICULTURE
-the Irrigation was developed in the Indus Valley Civilization by around 4500 B.C.

The size and prosperity of Indus Civilization grew as a result of this innovation, which eventually led to more planned settlements making use of drainage and sewers.

INDIAN ASTROLOGY
-Indian Astronomical text named Vedanga Jyotisa dates back around 1200 B.C. It detailed several astronomical attributes generally applied for timing social and religious events.
In India there is a long established widespread beliefs in Astrology and it is commonly used for daily life.

Examples: With regards to marriage, career
election process

Zinc Metallurgy

-Zinc mines of Zawar were active during 400 B. C.
-Another important Indian contribution was in the Isolation, Distillation and use of Zinc.

-A major breakthrough in the history of metallurgy was India’s discovery of Zinc Distillation whereby the metal was vaporized and then condensed back into pure metal.
-Early Iron objects found in India can be dated to 1400 B. C. Some scholars believed that by the early 13th century B.C. iron smelting was practiced on a bigger scale in India.
-Rust free steel was an Indian inventions and remained an Indian skill for centuries.

Mathematics

-the use of Negative numbers was known in early India and their role insituation like mathematical problems of debt was understood.
-the Decimal number system originated in India. Other cultures discovered a few features of this number system which was compiled in India where it attained coherence and completion.

Indian Inventions and Discoveries

Atomism

-The earliest reference to the concept of atoms date back to India in the 6th century B.C.

According to Democritus:
The term “atomos” meaning uncuttable or the smallest indivisible particle of matter.

Dharmakirti and Dignaga
-Indian philosophers and founder of Vaishehika School of atomism.
They considered atom to be:

- point sized
- durationless
- made of energy

CHANDRASEKHAR LIMIT AND NUMBERS

-discovered by the named after Subrahmanyan Chandrasekhar, who received the novel prize in Physics for his work on stellar structure and stellar evolution.

UNIVERSE

-the earliest known philosophical models of the universe are found in VEDAS, the earliest text on Indian philosophy dating back to the late 2nd millennium B.C. They described Cosmology in which the universe goes through repeated cycle of creation, destruction and rebirth.

INDIGO

-was used as a dye in India, which was also a major center for its production and processing.

FIREARMS

-by the 16th century Indians were manufacturing a diverse variety of firearms: large guns in particular.

-the Indian war rockets were formidable weapons before such rockets were used in Europe.

-Educational Reform ( Charles The Great)

7 Liberal Arts Tribium

(literary education)

Late Medieval Age
-William of Occam ( principle of parsimony)
-Jean Buridan ( most brilliant art master of MA ), theory of Imperatus
-Thomas Bradwardine ( Instantaneous Velocity )
-Nicole Oresme ( optics )

SCIENCE IN THE 19TH CENTURY

The last half of the nineteenth century was a period which experienced rapid progress in science and technology.

There were important breakthroughs in:
-iron and steel technology
-electricity
-weapons

-physics and chemistry
-sociology psychology and biology

There were numerous applications such as:
-ocean liners with steel hulls
-skyscrapers

-suspension bridges
-electric trolley cars

-the first subway

- central power stations

In the study of physics, there was a much improved understanding of the nature of matter :
Dalton, an English schoolmaster, postulated a theory in which the atom was conceived as being a tiny billiard ball. Material of the same atom were elements. Material combining different elements were compounds.

Dalton theorized that elements always combined in fixed ratios into compounds, as for example, in water, two atoms of hydrogen always combined with one atom of oxygen.

Atoms were the smallest indestructible parts of matter.
Mendeleev began to develop the table of elements which helped in the discovery of new elements.
In the last decade of the century, the discovery of radium by Marie and Pierre Curie, and the electron by Becquerel as well as observation of radioactivity in the laboratory, challenged Dalton's theory.
Einstein produced the theory of the conversion of mass into energy, E=mC(2), which was confirmed by laboratory observations.

A new theory of the atom was devised by the English physicist Rutherford in 1913. He conceived of the atom as consisting of a hard nucleus surrounded by a cloud of electrons.
The theoretical foundations for a whole host of new inventions in electronics and nuclear power was laid. In the field of social sciences, the study of Sociology was conceived by Auguste Comte, who wrote of a heirarchy of knowledge:
1. Theological (fictitious)

2. Abstract (metaphysical)

3. Scientific (positivist)

Each level of knowledge was said to be more sophisticated than the preceding level.
In Psychology, Sigmund Freud looked for explanations for individual human behavior beyond the rational level. He understood people to be motivated by a superego (a conscience), an ego (the rational mind), and an id (subconscious motivation).

In Biology, Charles Darwin developed his Theory of evolution. Traveling on a long voyage on the Beagle, he had the opportunity to observe great varieties of different species of life, some of which did not exist in England. He kept voluminous records which he later used to develop his theory.

Philosophical Analysis

Philosophical Analysis

-General term for the process used by the philosophers in analytic tradition that involve breaking down philosophical issues.

Major Function of Philosophy
1. to construct theory about man and the universe.
2.to examine very carefully everything that maybe offered for a belief and its own theories.

Analysis
-from the Greek word "analusis" which means to breakdown; is the process of breaking down topic or substances to gain a better understanding.

Three Main Ways of Forming Analysis

1.Explication - which was so called by Carnap who work largely in the construction of
symbolic language.
2.Redefinition-It is associated with More by replacing term or statement which have the
same meaning with the same sort of language but which more carefully
formulated and more clearly understand.
3.Illustration- which takes the opposite point of view holding who practiced by
Wittgeinstein by just keeping close to multiplying use of one term to
another.

KNOWLEDGE

-is defined expertise and skills acquired by a person through experiences or education.
-confident understanding of a subject with ability to use for a specific purpose.

The 4 matter of facts
1.that something that exist
2.that something can be known
3that there is something which matter
4.that something including the 4 going statement

Four Branches of Philosophy
1.Ontology-the theory of being
2.Epistemology-the theory of knowledge
3.Axiology-the theory of value.
4.Logic- the theory of inferences

Other Sources of Knowledge
*customs and traditions
*sense perception
*intuition

PERCEPTION
-is the process of attaining awareness of understanmding of sensory information.
-means "receiving, collecting action of taking possesion Apprehension with the mind or sense.

FOUR KEY WORDS
PERCEPTION-->EXPERIENCE-->KNOWLEDGE-->SCIENCE

THOUGHTS
-acts of thinking
-that which one thinks
-opinion and reflection

CONCEPTS
-are really habits of expectations
-serves as a representation of an object
-it is idea or mental image

PERCEPTS
-views
-reflection
-impressions

Titchener
===>used to report what came into his head ehen he was using certain ideas" image theory".
Hume
===>used by introspecting to discover what the self look alike."bundless of perception"
Ryle
===>used ask the questioned about the concept.
Heraclitus
===>he recognized in perception are more or less arbitrarily carved out of the continous stuff.

LANGUAGE

-is an abstract system of word meaning and symbol of all aspect of culture. It includes speech, written character, numerals, gesture and expression of non verbal communication.

The things in which the sign stands for:
*object
*sign
*interpreter

All language begin ordinary language under the process of immediate necessity of communication but not in all cases like.
1.customary usage how it spread
2.grammatical terms
3.declensions cases spread fall down.

Ordinary Language Analysis
- is the argumental that any language which is adequuate stands as the transmitter nuances or differences and styles of weaning on which every day conversion must be fluid.

CLASSIFICATION

-distinction, identification and organization of tw or more items, information and facts according to their similarities which are determine link between the objects being compared.

Definition according to Gottfried Wilhelm von Leibniz
-it is the differentiation of two or more objects which is not ever exactly alike essential dissimilarity.

Platos Theories of Universals
1.Universalia in re (universal in thing)-everything is combination of form and matter.

2.Universalia ante rem (universal before things)-the link between the members of the class is that they are all imitation of an archetype which existed before the word was made.

3.Universalia post rem(universal after the thing)-nothing general exist, only particular.


4 Different types of similarities in descending order of usefulness for purposes of identification.

1.Genetic similarities-similar origins.
2.Structural similarities-same constituents in parts.
3.Functional similarities-similar behavior.
4.Apparent similarities-,same physical features.
