Great Inventions
Many ideas and invention designs are groundbreaking. They have the potential to completely change the way we perceive the world and carry out our daily duties. Some inventions are so ahead of their time that they set the path for future generations to build on. Brilliant people build gadgets, vehicles, and just about anything else you can think of.
Fire
Although fire wasn’t technically invented, the ability to control fire was both fundamental and crucial for human civilization. Ancient humans who walked the Earth around two million years ago discovered and used fire for their benefit, but it wasn’t until 125,000 years ago that fire was fully utilized to the point where it was considered a tool.
Apart from giving us warmth in the cold and light in the dark, fire led us to develop skills like cooking. The ability to prepare healthier food and cleaner drinking water helped ensure not only human survival, but also higher intelligence due to proper nutrient intake.
Wheel
Many people think that the wheel is the greatest invention of all time. Around 3500 B.C.E., the Mesopotamians invented the wheel, but mainly for pottery-making. It took about three centuries before the first wheel was attached to a chariot and it could only get better after that.
In our modern life, we take the wheel as a ubiquitous piece of engineering that we rarely pay attention to. Before this invention came to surface, humans were limited in terms of transportation and haulage. That being said, the wheel was only one part of another life-changing invention: the wheel-and-axle. In other words, the idea of attaching a wheel to a non-moving platform in a proper configuration so the two could work together.
