The Wheel - Efficient yet Simple

"A wheel is a circular component that is intended to rotate on an axial bearing." Wheels are found almost every important place. They are visible mostly in transport i.e Vehicles, Bicycles to name a few. The biggest advantage of "the Wheel" is its ability to reduce friction greatly by rolling over any surface. Its one of the most efficient invention ever and there is no doubt that its creation is the reason for a lot of development today. It helps in faster and efficient communication, helps produce electricity, helps in steering (steering wheel), working of engines, and many more areas. Transport is by far is its biggest advantage. Without it we would still be unable to transport large goods or journey fast. We would have had to rely on animals and their bodies as concept of carts would not have been developed. The wheel today is used in countless mechanisms and is like electricity one of the most innovative invention of human history. So now we know its importance. But who did this great innovation and blessed the world with its advantages? Read more to find out.

Electricity - One of the Greatest Innovations in Human History

Electricity is the phenomenon associated with the flow of electric charges. And it has been present on Earth long before we humans knew of it. Lightening is one of the natural forms of electricity. But after the 18th century it started to find its way in human life. And it did it so successfully that today, Electricity is the most important aspect of our life.
