In today’s world, technology is developing at an unprecedented rate. The latest gadget today is tomorrow’s antique. As a result of this rapid development of technology we often take things for granted on of these is the wheel take a look around and you will see wheels everywhere be is as tyres on in everyday machinery. The wheel has even been imbued with symbolic meanings, most famously perhaps as a metaphor for the never ending cycle of life.

One may be tempted to think that the wheel is just a humble of even primitive invention compared to some of the fancy gadgets that we have today. Nevertheless the wheel (specifically as a means of transportation) was actually invented at a relatively late point of human history. The oldest known wheel found in an archaeological excavation is from Mesopotamia and dates.

This period was known as the Bronze Age, By this time human beings were already planting crops herding domesticated animals and had some form of social hierarchy.

One of the reasons why the wheel invented only at this point in history is due to the fact that metal tools were needed to chisel fin fitted holes and axles it his leads to the next reason.

The wheel was not just a cylinder rolling on its edge. It concept was a stroke of genius, but making it was a challenge. The ends of the axle, as well as the holes in the centre of the wheels had to be nearly perfectly smooth and round. Instead we should view it as one of the great achievements of human society.
