Science and Technology Data, only data

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

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)

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

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

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
