I. Movement of Ideas

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

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

4. Two types: Relocation and Expansion Diffusion

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

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

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

An Example from Mean Girls (*this is Ms. Cannon’s favorite movie)

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

b. Contagious Diffusion: Fast spread of an phenomenon throughout a population

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

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

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

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

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

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

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
