THREE-AGE SYSTEM

  • Classification: Developed by Christian Jürgensen Thomsen, an archaeologist and curator of the National Museum of Denmark, who classified ancient tools based on material composition.

  • Three Categories of Materials: Stone, Bronze, and Iron, leading to the designation of three pre-historical periods.

STONE AGE (2.5 MYA - 3000 BC)

  • This era is characterized by the invention and use of stone tools.

  • Tools were also made from wood, bone, and other non-metal materials.

  • Evidence: Artifacts and cave drawings serve as primary evidence of this era.

  • Example: Painting found in the Chauvet Cave in Southern France, dating around 32,000-30,000 B.C.

  • Context: The Earth was in an Ice Age during this period, affecting human habitation and activities.

SOCIAL STRUCTURE

  • Living Conditions: Humans lived in small nomadic groups focused on hunting megafauna and gathering.

  • Transformation from a culture of hunting and gathering to farming and food production was initiated.

SUBDIVISIONS OF STONE AGE

  • Paleolithic (Old Stone Age): Further divided into:

    • Lower Paleolithic: Characterized by the use of simple tools such as stone choppers.

    • Middle Paleolithic: Marked by the creation of more intricate tools, like bone needles.

    • Upper Paleolithic: Featured advanced communal hunting, fishing, and the emergence of supernatural beliefs and art forms.

    • Cultural Figures: Included notable hominins like Neanderthals, Denisovans, and modern Homo sapiens.

TOOLS OF PALEOLITHIC PERIOD

  • Tools made from stones, flints, bones, and antlers:

    • Examples: choppers, hand axes, harpoons, and needles.

  • Artistic Expression: Early humans left behind significant art, such as the "Venus Figurines"—over 200 statuettes of voluptuous female figures found in Upper Paleolithic sites across Europe and Asia.

MESOLITHIC PERIOD (Middle Stone)

  • The transitional stage between the Paleolithic and Neolithic.

  • Time of gradual transition to agriculture and more permanent settlements.

  • Continued use of microliths, a type of small, refined, and polished stone tool designed for spears and arrows.

NEOLITHIC PERIOD (New Stone)

  • Characterized by the development of agriculture through the domestication of plants and animals.

  • Technological advancements included:

    • Stone tools, pottery, and weaving.

    • Innovations such as hand axes for plowing and tilling.

  • This period saw the rise of urban civilizations and the end of the Stone Age marked by the introduction of metal tools.

BRONZE AGE (3000 BC - 1200 BC)

  • Notable for advancements in metalworking, particularly the creation of bronze through the smelting of copper and tin, with bronze consisting of approximately 88% copper and 12% tin.

  • Important Inventions: Notable innovations included:

    • Ox-drawn bronze plows

    • Potter's wheel

    • Irrigation techniques

    • Soap-making

    • Architectural structures such as pyramids and formation of early kingdoms.

IRON AGE (1500 BC - 450 AD)

  • Transition marked primarily by economic factors as iron became widely available and superior in military applications over bronze.

  • Significant Developments: This era began when advancements in smelting allowed the production of iron at higher temperatures, leading to the creation of stronger and more reliable agricultural tools, eventually refining into steel.

MIDDLE AGE (450 AD - 1450 AD)

  • Often referred to as the Medieval Age and labeled the "Dark Ages" due to perceived stagnation in scientific and technological advancements.

NOTABLE DEVELOPMENTS IN MIDDLE AGE

  • China: Innovations like acupuncture, paper-making (using bamboo soaking and screen-dipping methods), seismograph, movable-type printing, wheelbarrow, and gunpowder/cannon.

  • Europe: Development of the Feudal system, universities, clocks/watches, magnetic compass, horse-collar, watermill, and advancements regarding gunpowder.

  • India: Important developments in medicine, characterized by the collection of knowledge about diseases and astronomy. A year was systematically divided into 12 months, and advancements in algebra and geometry were recognized.

  • Pre-Columbian America: Cultures such as the Mayans and Aztecs made significant advancements in agriculture, architecture, and numerical systems.

SCENTIFIC REVOLUTION (1440 - 1690 AD)

  • Refers to the period of significant advancements in scientific inquiry, replacing philosophical views with empirical approaches facilitated by the printing press.

SIGNIFICANT CONTRIBUTIONS

  • Heliocentrism: Proposed by Nicholas Copernicus, positioning the sun at the center of the universe with Earth and other planets revolving around it.

  • Laws of Planetary Motion: Johannes Kepler's laws dictating elliptical planet orbits around the sun.

  • Physics: Galileo's work on motion, establishing the relationships among distance, velocity, and acceleration, and Isaac Newton's laws of motion.

INDUSTRIAL REVOLUTION (1750-1895)

  • Encompasses the extensive technological innovations leading to the mechanization of production processes, causing significant societal shifts.

  • Shifted manufacturing from small homes to factories and triggered migration from rural areas to urban centers for labor.

NOTABLE ADVANCEMENTS

  • Textile Industry: Introduction of the power loom and cotton gin as significant innovations.

  • Transportation: Development of mile-long canals, steamboats, and ships.

  • Communication: Emergence of the electric telegraph, telephone, and radio technologies.

ADDITIONAL ADVANCEMENTS

  • Lighting: Innovations like gas lighting, Bunsen burners, and electric lights.

  • Agricultural Practices: Introduction of seed drills and stock breeding techniques.

18TH TO 19TH CENTURY

  • The connection between science and technology evolved, leading to a unified approach that would stimulate technological and industrial growth.

NOTABLE ADVANCEMENTS

  • Physics: Major discoveries included electrostatic interactions, creation of batteries, and discoveries regarding X-rays.

  • Chemistry: Notable advancements included the development of thermometers, combustion experiments, and atomic theory.

  • Biology: Contributions included cellular discovery, microbial observations, and advancements in vaccination.

20TH CENTURY TO DATE

  • Marked by radical changes in science and technology, featuring new scientific theories that heavily influenced technological advances.

NOTABLE ADVANCEMENTS

  • Included Einstein's theory of relativity, discovery of atomic particles, and achievements in space exploration (e.g., first moon landing).

  • Technological innovations such as genetic engineering, cloning (e.g., Dolly the sheep), and various impactful inventions including:

    • Biogas systems

    • DNA fingerprinting

    • Cellular technology

    • Software innovations like web and gaming applications.

INFORMATION AGE

  • Encompasses the transformative period influenced by technology, enhancing the communication of knowledge and information dissemination.

GUTENBERG REVOLUTION

  • Ascribed to Johannes Gutenberg’s introduction of movable type printing in Europe (1455), revolutionizing the distribution of information and laying the groundwork for the Renaissance.

  • Notable Publication: The Gutenberg Bible, marking the initiation of widespread digital information.

DIGITAL AGE

  • Represents the evolution of technology away from traditional printing methods toward computers, cellphones, and other digital tools facilitating information distribution in an unprecedented manner.
