Our world has experienced many many revolutions. Times of incredible leaps in technology and mechanical engineering, though we are constantly closer to the next revolution than it may appear.
As historically it has revealed itself, the nature of mankind's increasing intelligence does not rely on similar repetition and small incremental improvements but instead in radical changes to familiar processes, resulting in a surprising discovery, soon to change the world.
However, there have been many close calls throughout history.
For example, in the first century AD, the Greek engineer, Heron of Alexandria invented the first steam engine. He named it the aeolipile and was unaware that his creation, though frivolous and impractical at the time, was just a few minor tweaks and reappraisals away from igniting The Industrial Revolution. Almost 2000 years earlier than it actually occurred.
Similarly in the 9th century, in Cordoba, Spain, the inventor Abbas ibn Firnas threw himself off of a tower and tried to fly. He managed for a short while but could not control his descent.
His contraption was missing only the yet to be discovered necessary adaptation being a horizontal tail fin. Coming dangerously close to solving the mystery of human flight, centuries before it would become a reality.
This begs the question, what potentially revolutionary secret are you holding onto?
How drastically could you change the world if you put it into motion?
