High Street in Salisbury is the avenue between the cathedral and the comercial Bridge Street and walking through it I’ve seen that there are some mathematical pictures on the floor:

The spiral packs

The sphere isn’t the only figure exhibited in Cosmocaixa. “The spiral packs” and we find it in the nature and in our quotidian life:

The spiral is a circumference that twists away on the plane that contains it. It is the best way of growing without occupying too much space. It is frequently found in animals when there exists the contradictory need for something massive, voluminous, broad or long that does not affect mobility (horns, tails, tongues, trunks, shells, etc.) and in plants to grow something that will subsequently be unrolled. If we unrolled all the spirals we have at home (kitchen and toilet paper, audio and video tapes, adhesive tape, records, springs,…) we would be forced to leave the house, as we would not all fit.

One of the best examples of a spiral in the nature is the  the Nautilus shell:

Apart of some different shells, we also find vegetables and fossil:

Are there more shapes to study?
