Ernst Heinrich Philipp August Haeckel was a prominent comparative anatomist and active lecturer in the late nineteenth and early twentieth centuries. He is most well known for his descriptions of phylogenetic trees, studies of radiolarians, and illustrations of vertebrate embryos to support his biogenetic law [4] and Darwin?s work with evolution [5]. Haeckel aggressively argued that the develop...

Reinhart Heinrich, former professor at Humboldt University, Berlin, and bestknown as a founder of metabolic control theory, died October 23, 2006, at the age of 60. Among his many services to the scientific community, Reinhart was associate editor of PLoS Computational Biology. His far-reaching theoretical work on metabolism, signal transduction, and other cellular processes has made him one of...

Johann Heinrich Lambert is best known for his work in physics. The law of Bouguer-Lambert-Beer on the absorbtion of light may be his most famous achievement. He is also well known in mathematics, for example for his proof of π and e being irrational numbers, for his work on non-additive probabilities and for his contribution to non-Euclidean geometry. He worked on numerous problems of natural s...

one of the most important factors that affect tire friction is surface roughness, which determines the size of the real contact area, real pressure distribution on the contact interface, and scales of mechanical engagement between viscoelastic rubber and a rough substrate. the need to predict coefficient of friction (cof) for rubber on rough surfaces for applications such as traction of tires o...
