4. Objective:
You will be able to explain how technology, population, and distance affects interaction between places in writing with at least 90% accuracy.

5. Fun Fact
Human salvia has a boiling point three times that of regular water.

6. 80/20 - Testing
Front side is done individually – 80% of the quiz grades
Map side is done in your tables – everyone will need to write on their own piece of paper, but can talk. – 20% of the quiz grade

7. I. Movement of Ideas

8. Diffusion: how something spreads across space over time
Hearth: birthplace of an idea or item
Diffusion only works if the characteristic is accepted by the new place

9. 3. Tobler’s Laws of Diffusion
Law of the Few – ideas/items end up diffused because of the efforts of a few well connected people
Stickiness Factor – How well the idea resonates with the new place
Power of Context – Needs to be the right time/place

10. 4. Two types: Relocation and Expansion Diffusion

11. Relocation Diffusion: When an idea spreads because people move from place to place.
Example: Language

12. In Your tables….
List three examples from world history of Relocation Diffusion on your white boards

18. Hierarchical Diffusion: Idea comes from people or places of power/influence
Reverse Hierarchical Diffusion: starts in obscure places and works its way into power
Example: Tea Party

23. c. Stimulus Diffusion: spread of the underlying idea, not the
c. Stimulus Diffusion: spread of the underlying idea, not the specific one -The concept spreads, not the item

24. In Your tables….
List three examples from history of Stimulous Diffusion on your white boards

25. B. Interaction
Tobler’s First Law: Civilizations that are close together interact at a higher rate than civilizations farther apart.
Close = more interaction
Far = minimal interaction

26. interaction goes down the greater the distance
2. Friction of Distance:
interaction goes down the greater the distance
Distance Decay

27. 3. Space-Time Compression: how long it takes for a person or idea to travel has gone down as technology improves

28. Send someone from your group to get white boards! Get out your marker!

29. Iij = PiPj Dij2 4. Gravity Model
An equation to measure the level of interaction between two places based on distance and population
Iij = PiPj
Dij2
I = level of interaction
P = population
D = distance
i = place 1
j = place 2

30. Practice Phoenix – 3,600,000 Tucson – 840,000 Bisbee – 5,300
Distance between:
P & T = 110 miles
T & B = 80 miles

Practice
Los Angeles – 13,000,000
Chicago – 9,500,000
Philadelphia– 6,000,000
Distance between:
LA & C = 1,700 miles
LA & P = 2,300

32. Practice London – 14,000,000 Beijing – 24,900,000
