During the 20th century, astronrmy split into two major categories:
OBSEVATIONAL ASTRONOMY- focused in aquiring data from observation w/c then analized by the aids of basic priciples of physics.
THEORETICAL ASTRONOMY- oriented towards the development computer or analytical models to described astronomical object and phenomena.
Contributions of Early Civilization
BABYLONIANS- beginning of mathematical and scientific astronomy, discovered the luar eclipse.
GREEKS 3RD B.C.- ARISTARCUS, calculated the mass of the earth and measures the distance and size of the moon and star. HIPPARCHIUS, invented the 1st astronomical device such as 'astrolabe'. ANTIKETHERA Mechanism, an early analog computer designed to calculate the location of moon,earth, and sun.
PERSIANS- AZOPHI, discovered the andromeda galaxy and described in his "book of fixed stas".
EGYPTIANS- ALI IBN RIDWAN, 1st observed the super nova 100G, the brightest apparent magnitude stellar event recorded in the history.

SCIENCE IN GREEK AND ROMAN CIVILIZATION
-GREEK CIVILIZATION, emerged around 1100 B.C.
-EARL GREEK
S have been fully developed basic elements of mathematics, astronomy, physics, and medicine.
Persons who give contributons to the development of Science
Thales- matter was composed of convertible into water
Hippocrates- father of medicine
Aristotle- classification of plants and animals
Phythagoras- phythagorean Theorem
Archimedes- principles of lever and pulley
Ptolemy- geocentric theory
-ROMAN CIVILIZATION, time of Julius ceasar. it is said that Roman are poor in Science but contributed alot in the field of infrastracture.
-ROMANS that contribution in the field of Science
Pliny The Elder, only roman scientist that is celebrated
Galen, wrote 150 books of medicine
Cleopatra, roman queen who uses cosmetics
STONE AGE TECHNOLOGY
Earliest Communities
live alost entirely in small nomadic communities
surviving on his skills in hunting and fishing
developed in tropical latitudes, especially in africa
moved out thence into the subtroical regions and eventually into the landmass of eurasid
Neolitic revolution
-Primitive man used wood, bone, fur, leaves, grasses
-Stone, material that gives its name and technological unity, became tools when they were shaped it.
-Flint, became a very popular stone for this prpose, although fine sandstones and certain volcanic rocks.
-Fire, most important contribution of pre historis to power technology.
Tools and Weapons: stone headed spear, harpoon, bow and arrow
Other Devices Invented: potter's wheel, wheel, drill and latthe
Food Production: Paleolithic- gathering, fishing and hunting. Neolithic- agriculture, animal husbandry
BuildingProduction: 1)impresive structures where created 2)primarily tombs 3)burial mouds and religious edifices 4)sun-dried bricks for domestic housing
Manufacturing: griding corn, baking clay, spinning and weavening textiles, dyeing, dosmetication, dugout and birch-bark.
