Inventing the wheel together

Let's try to open something together. Of course, we will not think up a new one. But let us trace the way to all already known such an invention as the wheel. It is believed that the wheel invented by man. First, we'll determine what a wheel is. It's a device that rolls. But if you look more closely, the wheel does not actually roll. What kind of word is it? It seems that there is no such thing in physics. I think that the prototype of the wheel, there were human legs. The legs allow you to move (move the weight of our body), without slipping, I place emphasis on the feet. It's clear? The key here is the movement and non-slip. Now compare the legs and the wheel. In fact, this is the same mechanism. To continue the logical chain, add more legs. Let's say six on each side. And you will see the law. You do not need to rearrange your legs, but enough to rotate about the axis. Each next leg will lean on the ground, allowing you to move your body forward. Such a walking wheel. Later, the number of spokes (legs) increased for smoothness, and then completely rimmed the rim. In this form, the wheel has reached our days. But we already know that the mechanism of the wheel is based on "multi-legality" (a strange word). Our wheel has many legs, which eventually merge, at the level of our perception. If we increase the place of contact between the wheel and the road with an electron microscope, we will see that this is a point-support (modern leg). What seems to us to be round, in fact, consists of protrusions. Of course the real wheel is not perfect. And when in contact with the road, losses occur, as a result of the appearance of a "frictional force". The force of friction is the slip of the wheel. The wheel turns, but the car does not move - the result is the wheel is erased. This is because the materials of the wheel and the road, to combine is not ideal and depends on the style of riding. The more we put pressure on the gas, the more effort is expended on the wheels. Rubber, slips and wears off. Rubber is a material that is softer in comparison with a road surface. That also leads to erasure. So could the way of life from foot to wheel.
Although the discoveries are a matter of chance, yet they are not subject to all. Most likely you need a certain mindset. Many inventors have made not one but several discoveries. And observation plays the last role. Desire to solve riddles or get answers to questions. Newton spent many hours pondering and meditating on the gravity of the earth. And more importantly, any discovery is a collective intelligence, even if it belongs to one person. But this was preceded by the tremendous work of a large number of people, the accumulation of certain knowledge, over a long period of time, which served as the basis for the invention or discovery.
