  1. Big Geography The Geography of Global History

  2. Hi. I’m Mundo. Did you know that how we “see” the world depends on how we project the world?

  3. The Earth is a sphere. Therefore, it cannot be projected on a flat map without distortion. The question is, which kind of distortion?

  4. We need a mental picture of the whole world, not just certain parts of it. This is “big geography.”

  5. Africa U S A. South America

  6. Three World Map ProjectionsMercator, Peters, and Robinson

  7. On a Mercator projection, invented by Gerardus Mercator in 1569, any straight line is a line of constant compass bearing. This enables a navigator to plot a straight-line course.

  8. Despite the values of the Mercator Projection, it distorts the size and shape of land areas. Fact: South America is 8 times as large as Greenland. Fact: Africa is 14 times as large as Greenland. The Peters Projection is an “equal area” map. It represents areas accurately, but it seriously distorts shapes. Compare the size of Europe to Africa on the two maps. Compare the size of the former USSR to China on the two maps.

  9. It is about perception.

  10. What do you see? A woman or a saxophone player?

  11. What do you see? A Grandma or an upside down princess?

  12. What do you see? An older woman in a scarf or a young woman looking away?

  13. What do you see?

  14. Why are we even doing this?What does it have to do with class?

  15. Perception! • People perceive things differently and it is important that we realize that!
