  • In February 1990, Voyager 1 took one last photograph of its home planet. Earth appeared as a tiny blue dot in a vast sea of darkness. From http://www.carlsagan.comHumanity and History in Perspective /*HUM 110 PowerPoint 2

  • How old is human history?The most instructive way I know to express this cosmic chronology is to image the fifteen-billion year lifetime of the universe . . . Compressed into the span of a single year. . . . It is disconcerting to find that in such a cosmic year the Earth does not condense out of interstellar matter until early September; dinosaurs emerge on Christmas Eve; flowers arise on December 28th; and men and women originate at 10:30 p.m. on New years eve. All of human history occupies the last ten seconds of December 31; and the time from the waning of the Middle Ages to the present occupies little more than one second. From Cosmos by Carl Sagan.*HUM 110 PowerPoint 2

  • First stage of human history: Nomadic Society

    Nomads:humans who lived by hunting and gatheringImportant innovations included:Fire:1.5 M years agoStone tools:100,000 years ago*HUM 110 PowerPoint 2

    HUM 110 PowerPoint 2

  • Second stage:Shift from nomadic to agrarian society (about 8,000 BC) Cause:Technology allowed man to produce a reliable, ready source of food.

  • The theory by Maslow (a 20th century psychologist) states that people will always address their most basic needs such as securing food, water, air, shelter, sex, etc. before being concerned with higher level goals, such as the needs for security, belonging, self esteem, and actualization.

    This 20th century theory offers a clue about why the earliest technologies helped humans to meet their most basic need: a reliable source of food.

    For example, a simple rock when attached to a stick became a TOOL to more efficiently secure food. Later this might be used as a simple plow.

  • British Agricultural Revolution 1500-1850 in EnglandMassive increase in agricultural productivityCauses:Enclosure (fencing in grazing areas for animals)Crop Rotation (avoiding soil depletion by growing different crops from year to year)Selective Breeding (reproducing the best animals and crops)Mechanization*HUM 110 PowerPoint 2

  • 1750-1850:First Industrial RevolutionEconomy based on manual labor switched to one based on machine power.Major invention: Steam engine (invented in early 1700s) used in transportation, textile manufacturing, and metallurgy.*HUM 110 PowerPoint 2

  • Not all results are positive:

    Luddites: The Luddites were a group of craftsmen and British textile workers who were displaced by the innovations and mechanization of the textile industry. These workers organized about 1811 to protest these changes. The protests often involved destroying machinery which they viewed as threats to their livelihood. Luddite is still a term used now as a synonym for people distrustful of technological advancements.
