Almost every people in the world know Thomas Alva Edison, an inspiring inventor from the US who was famous with his invention which became a benchmark of the beginning of modern era: the bulb lamp. He was also the one who found camera and direct current electric excitation.
In 1911, Miami Metropolis asked Edison for a brief prediction on a hundred year in the future, which meant the year 2011. As quoted from the Washington Post, Edison said that in 2011, electricity will replace steam power as train main power. Also, he predicted that air transportation would be a daily transportation. Moreover, Edison also predicted that steel would get cheaper and cheaper and thus make it a common material for building construction. All of those predictions are now proven, but there was one prediction that struck all of the heaps. He predicted that there would be a two-inch book with thousands of pages. And guess what? We now have iPad and other e-book readers.
However, not all of Edison’s predictions were accurate. His inaccurate prediction was that human would find a way to transform iron into gold. Unfortunately, that prediction is still trapped in human imagination.
