I believe there is much more truth in this than most recognize. Perhaps the knowledge that Watt produced in England, which allowed the British to extract coal from mines at levels that normally flooded, power steam ships and factories, etc. was the real basis for the British domination of the world. Before them, the Spanish with their great ships and influx of gold (Information and technology based, if you want to consider why THEY got the gold.) led to world domination. In America's case a lot had to do with the great expanses of productive land tied together by the railroads. Today the internet is transporting information around the world in seconds. (as I recall my history, the US fought the Spanish for the Philippians about a month after peace treaty was already signed, due to communication lags of that era.) Now there is a good chance that an X-ray you have taken in a hospital in the afternoon, will travel thru the internet while you sleep and some Indian doctor, working during your night, will interpret it, write the report and next AM the report will be in your hospital records. Like wise, when I had a problem with the computer am typing on, an Indian expert help talk me thru the solution as it was still under warranty. It is technology, not natural resources or agricultural potential, that is the foundation of modern great nations. There is no reason to think the US can stay on top. The US fall will be much quicker than in the past and is now in progress, but few recognize this yet. I foresaw this a few years ago, became concerned. Although I live in Brazil, a "nation of the future," all my children and grandchildren live in the US. I wrote book Dark Visitor as something I might be able to do to help them. (It is a physics book, disguised as a horror / cosmic disaster story - which might be true fate of the Earth.) I wrote it because, as retired professor, I have watched US university science classes fill with hard working, serious Asian students, whom one must admire, but who will (and are) taking their skills back to Asia now more than ever before. I.e. Dark Visitor is intended as a recruiting tool for science students as it may appeal to some good minds that would never consider opening a science book on their way to becoming lawyers, brokers, etc. America is losing technological leadership to Asia. I am happy to announce that my webpage (www.DarkVisitor.com) is back up after being down for months. More of my concerns are there.
