The above chart depicts material discoveries dating back to 100,000 BC. It is, however, crucial to add some cultural background to the chart in order to better understand the impact of these findings. Around 10,000 BC the Mesopotamian civilization arose and through it's history discovered and invented many new technologies, allowing for further advancement throughout the ages. Papyrus was used as paper by the ancient Egyptians as early as 3000 BC, allowing for written history to start to take shape. In 332 BC Alexander the great conquered Egypt and eventually established the great library of Alexandria, using many of the same resources discovered prior to his take over, including papyrus. Centuries later, the lightbulb was invented (1879). This allowed buildings to provide light after sundown without major fire hazards. This was a huge push for the technology snowball, and from then on it was a race downhill. The industrial revolution followed soon after, giving rise to booming businesses and industry tycoons which only expedited the inflow of new technology and discovery. Just over 100 years after the invention of the lightbulb, personal computers were made available by Steve Jobs, the founder of Apple. The chart clearly demonstrates the exponential growth process of technology and leaves the viewer in wonder of the next great achievement.
