We will explore circles and wheels in a new angle in this article. We know wheels and circles are everywhere. The wheel is highly useful as a 'moving device'.
In an artificial world, we find wheels everywhere. If they are so efficient, why does not nature use it? But all animals have legs, not wheels. The most likely reason is that wheels need axles; if wheels were part of the animal's body; the animals would need axles too. These axles would have to carry the sinews and blood vessels and after a couple of rotations, they would become horribly twisted. Hence the wheel and axle are impossible biologically.

If you drag any object on the floor, it will be difficult and will consume a lot of energy. But if you roll anything (a wheel), the surface of contact is minimum; the surface of contact remains stationary at a moment. Friction is greatly reduced. Hence the wheel rolls easily consuming less energy.
The circle contains the largest area for a given perimeter. The sphere contains the largest volume for a given surface area. So, the water drops, fruits pebbles are spherical.
If the circle is highly efficient, honeycomb should contain circular cells. But it does not, why? If you stack cylinders, spheres, and circles, one over the other, row after row, there will be a lot of gaps, and space is wasted. Efficient packing and strength are important qualities in nature, and no more so than in a beehive. Bees can use square cells. But they are not as efficient as a circle. The hexagon shape is closer to circle and also they fit properly with each other without leaving any gaps. Hence bees (nature) has selected hexagon instead of a square or a circle.

The hexagon is the highest order of polygon that can be used to tile a floor without leaving any gaps.
Oscillations and waves have the repetition of motion like circular motion. Hence the properties of the circle can be applied to them. Nature's constant pi=3.14...plays a key role in all these shapes.
