Material Strength
These sponges skeletons have amazing geometric configurations, which have been extensively studied for their stiffness, yield strength, and minimal crack propagation. An aluminum tube (aluminum and glass have similar elastic modulus) of equal length, effective thickness, and radius, but homogeneously distributed, has 1/100th the stiffness.

Famous quotes containing the words material and/or strength:
“In the wildest nature, there is not only the material of the most cultivated life, and a sort of anticipation of the last result, but a greater refinement already than is ever attained by man.... Nature is prepared to welcome into her scenery the finest work of human art, for she is herself an art so cunning that the artist never appears in his work.”
—Henry David Thoreau (1817–1862)
“My strength is as the strength of ten,
Because my heart is pure.”
—Alfred Tennyson (1809–1892)
