In the real world you may have seen some of the terms in the chart below. It shows both expansion and decay based on exponential change. You will hear a lot about nano technology in months and years ahead. It is effectively 1 billionth of a meter. This is very small.
The promise is that it will lead to fundamental changes in everything from energy to manufacturing. Since computing power is on a course to double every 20 months or so, in 15 years we will see it grow from a relative 1 to 2^15 which equals 32,768. By the way, that would make a $1000 MacBook Pro worth less than a Nickel.
That amount of computing power for the same price we pay for a single unit will lead to a level of progress in Nanotechnology that is hard to comprehend.
|10−1 m||dm||decimetre||101 m||dam||decametre|
|10−2 m||cm||centimetre||102 m||hm||hectometre|
|10−3 m||mm||millimetre||103 m||km||kilometre|
|10−6 m||µm||micrometre||106 m||Mm||megametre|
|10−9 m||nm||nanometre||109 m||Gm||gigametre|
|10−12 m||pm||picometre||1012 m||Tm||terametre|
|10−15 m||fm||femtometre||1015 m||Pm||petametre|
|10−18 m||am||attometre||1018 m||Em||exametre|
|10−21 m||zm||zeptometre||1021 m||Zm||zettametre|
|10−24 m||ym||yoctometre||1024 m||Ym||yottametre|
|Common prefixed units are in bold face.|
So, this is why an understanding of scale and exponential growth and decay is so critical. Every individual and enterprise will be faced with and amount of change that will challenge the status quo. It's not in 100 years, it's around the corner.
