In most traditional engineering applications, structures are designed to be stiff such that the loads they must bear do not deform them substantially. In nature, the contrary is true. Especially when it comes to fluid loading, natural structures tend to be compliant and flexible whereas man-made structures are rigid and unyielding. Plants, which seek to maximize their surface area to capture the most sunlight, make use of their flexibility by changing their shape when they are subjected to a fluid loading, whether water flow or wind. We say that they reconfigure.

在大多数传统的工程应用中，结构被设计成刚性的，这样它们必须承受的载荷不会使它们发生很大的变形。在自然界中，情况正好相反。特别是当涉及到流体载荷时，天然结构往往是柔顺的，而人造结构是刚性的，不屈服的。植物，寻求最大化它们的表面积来捕获最多的阳光，利用它们的灵活性，当它们受到流体负荷时，无论是水流还是风，都会改变它们的形状。我们说它们重新配置。
