Bastian and Pasteur on Spontaneous Generation

In the present analytical study, we consider the problem of a nanocrack with surface elasticity interacting with a screw dislocation. The surface elasticity is incorporated by using the continuum-based surface/interface model of Gurtin and Murdoch. By considering both distributed screw dislocations and line forces on the crack, we reduce the interaction problem to two decoupled first-order Cauchy singular integro-differential equations which can be numerically solved by the collocation method. The analysis indicates that if the dislocation is on the real axis where the crack is located, the stresses at the crack tips only exhibit the weak logarithmic singularity; if the dislocation is not on the real axis, however, the stresses exhibit both the weak logarithmic and the strong square-root singularities. Our result suggests that the surface effects of the crack will make the fracture more ductile. The criterion for the spontaneous generation of dislocations at the crack tip is proposed.

AbstractHis admirers assert that the first English dictionary was Johnson’s but this is denied by antagonists who cite late medieval and early Renaissance lexicographers such as Thomas Elyot, Thomas Cooper and John Florio. The admirers emphasize Johnson’s merit above earlier authors and assert innovations to the form. This paper shows both views are limited and lexicography has a much greater antiquity seen in Athenaeus and earlier. All these works, which were composed over thousands of years, did not come from Evolution where Athenaeus is a common ancestor. Instead they are products of literary Spontaneous Generation, showing that Homo est animal grammaticum.
