Is orthogonality found in nature?

October 12, 2009


I wonder whether orthogonality is found in nature? We can dictate a direction with an axis and its spin about that axis with a second axis – the third axis is really a product for keeping the second orthogonal to the first.  I wonder whether this is needed in nature or whether it copes quite well with skew? Skew itself seems quite common in nature and the very fact that skin, muscles, etc skew is important for flexibility, movement and kinesis.

I wonder if allowing a transform to skew, without affect its scale has benefits to rigging. Tensegrity and its biological form certainly allow for skew against multiple planes, and the fact that they work under tension allows them to always find a resolution.

Biotensegrity: The geometry of Anatomy

October 2, 2009


This is something I’m very interested in, its the study of tensional integrity (Buckminster Fuller) in biology. From an aesthetics point of view it would probably fit in the field of  dynamics – but I’m coming from the standpoint of evolutionary kinematic constraints. Essentially that the notion of our evolutionary movement can only conceivably  end up in our current form. Our wrists, shoulders, hips, spine etc can only work they way they work, because its the only way they can.

Now I’m not including ideas such as being double jointed etc, but from a general standpoint I find the ideas found in biotensegrity a sort of bridging of the mathematical  models we create in rigging and real world biology. We both end up with the same results – e.g. the spine in a tensegrity model and a mathematical one have the same limits, rotation spaces and constraints.

It is said that mathematics is a poor man’s representation of nature – but the fact that it can represent it with enough detail as being real its pretty exciting to me. Tensegrity i find is a beautiful connection between nature and maths.
