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

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.

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.

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.
