  1. Science and Technology Data, only data

  2. Science and Technology - Foundations • Continuity from Paleolithic times • Some peoples remain using stone age technology • “science” is often based on superstition • Changes • Societies move to iron, away from bronze • Desire for better weapons drives technological advances • Desire for better agricultural tools drives technological advances

  3. Science and Technology – 600-1450 • Continuities • Desire for better weapons drives technological advances • Desire for better agricultural tools drives technological advances (i.e. irrigation systems) • Iron technology continues • Changes • Invention of heavy plow allows agriculture in areas with poorer soil • Invention of horse collar makes horse a viable agricultural power source. • Gunpowder developed • Moveable type invented in China • Naval technology continues to improve(Compass and stern post rudder)

  4. Science and Technology – 1450-1750 • Continuities • Desire for better weapons drives technological advances (but change too: bigger cannons, simpler guns) • Desire for better agricultural tools drives technological advances • Changes • Naval technology continues to advance (Lateen sail, caravel) • New scientific tools like microscope and telescope make science more scientific • Printing press

  5. Science and Technology – 1750-1900 • Continuities • Desire for better weapons drives technological advances (but change too: maxim gun, rifle, pistol) • Desire for better agricultural tools drives technological advances (but change too: seed drill to McCormick reaper) • Changes • Idea of interchangeable parts standardizes machines • Bessemer process allows for production of inexpensive steel • Industrial Revolution technology (spinning jenny, steam engine, railroad, etc) • Communication technology (telegraph, telephone, etc) • Medical technology like quinine and anesthesia developed

  6. Science and Technology – 1900 to Present • Continuities • Desire for better weapons drives technological advances (but change too: jet engines to A-bomb) • Desire for better agricultural tools drives technological advances (but change too: tractors to green revolution to genetic manipulation) • Changes • Space race improves education in science and technology • Computer technology allows for easy storage and sharing of information • Medical technology extends life expectancy
