INVENTIONS: THE WHEEL

THE WHEEL

The wheel is perhaps the man's greatest invention. It was invented a long time ago. The oldest wheel known was discovered in Mesopotamia.

At the very beginning the idea of wheeled transportation may have come from the use of logs for rollers. The oldest known wheels were made of wood.

We don't know who invented the wheel. But we have to be grateful. Thinks of what the world would be like without it: no bicycles, no roller-blades, no cars, no trains, no buses...
