The Hexagonal Bee Model

Have you ever wondered why the honey comb cells of a bee are hexagonal. The following idea I heard from a rabbi.

The strongest shape to use in such a structure is a circle, so why aren't bee hives cells made in a circle structure? The answer is that it involves too much wasted space. If the cells were circular then there would be alot of wasted space between each cell.

With this logic one can argue that the best approach would be to build the cells in square shapes as this would be easiest to do and would involve no wasted space. Surely this would be a lot easier than building a complex hexagonal structure?

The answer given is that although a square structure would be most efficient it changes the "ideal" strucutre of a circle too much. The difference between a circle and a square is too great, therefore a hexagonal structure comes as the closest substitute.

From this we can learn a valuable lesson.

Often a theoretical model provides the best solution, but in practise it is often not practical to implement, the principle learnt from the bee cell within the hive, is do not vary the model too far from the original solution. If you need to make changes then do so but always try and keep as close to the orginal model as possible.

It is this principle which I wish to extrapolate into the basis of my theory on Macro-Economics.
Adam Smith's invisible hand has come the closest to describe the perfect market. Let us make changes where necessary but remember not to move too far from the original model.
