What a waste of material, what a need for nutrients and energy to prepare this material, and what a competitive disadvantage against the neighbouring tree, which boldly and somewhat light-heartedly grows up tall

George B. Kauffman (Professor of Chemistry)ree has fallen away or rotted. The two components are pleasantly similar in conception, and both certainly satisfy the axiom of uniform stress for their loading. The fact that they have arisen in different ways is unimportant, but the question of what distinguishes the adaptive potential of their de

It is more accurate to imagine jumping up beneath a high washing-line and hooking on to it while swinging freely: a dynamic process which would arouse some self-doubt in even the fittest finger-wrestler. And yet this kind of load is what happens when a tige

Soddy and the Classification of the Elementsit is already a simply curved shell. One example known to us all is the thin-walled tube. If this tube also changes its diameter along a curve in the axial direction, it is a doubly curved shell (Fig. 141).

The Suicidal Success of RadioChemistryproduct, in contrast to nature. For example, if human life is involved, then we cannot approvingly accept the fracture of some motorcycles in order that this model gets by using less fuel. As already mentioned, nature does not know this scruple. Some of the following examples are industrial commissi

https://doi.org/10.1007/978-1-349-01476-7 for these external circumstances. So far, so good. However, in many cases this specialization is associated with a poorer suitability of the design with respect to other cases of load inappropriate to it, against which the component is thus sensitized. We have seen a simple example in the spiral gr
