  2. Time-space convergence? Friction of distance? Friction of Distance The notion that distance usually requires some amount of effort, money or energy to overcome. Because of this "friction," spatial interactions will tend to take place more often over shorter distances; quantity of interaction will decline with distance (distance decay).

  3. Why does greater ‘distance’ = greater ‘cost’? • What factors might contribute to the cost? • Remember, costs don’t always have to be financial. Where have we seen this before?

  4. Why is the world said to be ‘shrinking’?

  5. Imagine it is 1492, and you are Christopher Columbus. • How long will it take you to travel from Spain to the Americas? • And then to return back to Spain? • What problems (costs) would you likely encounter? http://www.christopher-columbus.eu/timeline.htm

  6. And today…

  7. In your groups, investigate the relative changes (history and development) of your allocated transport method: ROAD – Edric, Jasper, Tushaar, Arpit AIR – Marco, Nick, Kana RAIL – Rachel, Larry, Heather OCEAN – Grace, James, Claudia PIPELINE – Patricia, Victoria, Himani Explain how their development links to the space-time convergence and reduced friction of distance.
