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).
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?
Why is the world said to be ‘shrinking’?
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
And today…
In your groups, investigate the relative changes (history and development) of
your allocated transport method:
ROAD – Edric, Jasper, Tushaar, ArpitAIR – Marco, Nick, KanaRAIL – Rachel, Larry, HeatherOCEAN – Grace, James, ClaudiaPIPELINE – Patricia, Victoria, Himani
Explain how their development links to the space-time convergence and reduced friction of distance.
