How long is a piece of string? Finally the answer!

How long is a piece of string? Depends on how you measure! No it's not a cop - Here's why ...

To understand this concept consider the extent of the length of the coast of Norway. If we take an atlas and go to pages with the Scandinavian countries and for a 12-inch rule, we can begin moving the ruler of the entire coast of the marking tenth of an inch, where a number of messages and output in inches or in which the Coastal is all right. We add all and get the length of the Norwegian coast. Easy!

But he notes in the back of the atlas is a special page that Norway and you do begin to test again, but this time shows use millimeters instead of inches, because it is more accurate. This page only shows details of the coast and there are a lot more ins and outs of not measuring or counting, when the coast is longer than the first measurement.

But then, remember the Google GMAP pedometer. It is more accurate. So you go online and traces its way through the Norwegian coast with the highest detailed picture of Norway, you can get. You can find more ins and outs did not have the time, measured before and these add up to a much more precise and longest coastline.

So now, if you really visited Norway to our millimeter ruler and marched along the coast of Measure around each stone, gravel, each grain of sand, which define, on the coast?

The more details you can see what we are trying to measure and the smallest units are used to is the most accurate measurements to be our measure.
Measure a piece of rope that the extent of the Norwegian coast. A piece of rope with a microscope will be a lot more ins and outs than the eye.

Imagine if you could magnify the piece of twine million times and in millionths of a millimeter can be measured - how long will be this piece of string to 3 inches?
