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

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
