Technology refers to the application of scientific knowledge for practical purposes, especially in commerce and industry. Technology is often created to solve a problem, achieve a goal, or improve upon a pre-existing technology. Technology has heavily impacted cultures, economies, societies and politics throughout time and across the world.
Technological development began around 2.5 million years ago, when the Olduwan stone tool trade turned out hand axes and flakes. Throughout the ages, several technological revolutions took place that have brought with them immense innovation. In the past 2,000 years, humans have gone from pioneering simple agricultural techniques to building complex computerized structures. (Photo: Wikimedia Commons)
