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:
“This is no war for domination or imperial aggrandisement or material gain.... It is a war ... to establish, on impregnable rocks, the rights of the individual and it is a war to establish and revive the stature of man.”
—Winston Churchill (18741965)
“Being a parent is a form of leadership. . . . Parents make a mistake, along with leaders of organizations, when they are unwilling to recognize the power inherent in the positions they occupy and when they are unwilling to use this power. . . . I do not mean a figure who is irrational, autocratic, or sadistic. I mean leaders who have the strength of character to stand up for what they believe.”
—Abraham Zaleznik. In Support of Families, ed. Michael W. Yogman and T. Berry Brazelton, ch. 8 (1986)
