Hierarchy of wool fibers and its interpretation using E-infinity theory

Why do wool fibers show excellent advantages in warmth-retaining and many other practical properties? The paper concludes that their hierarchical structure is the key. Using Einfinity theory, its Hausdorff dimension is estimated to be about 4.2325, very close to El Naschie’s E-infinity dimension, 4.2360, revealing an optimal structure for wool fibers.
