A Personal History of the Development of Transformation Toughened PSZ CeramicsThe author has been working exclusively with zirconia materials during the past two and a half decades. This effort culminated in the discovery of transformation toughening. An outline of the work leading up to and subsequent to this invention is presented here.

Caustics in time reversible hamiltonian systems,We consider the projection to configuration space of invariant tori in a time reversible Hamiltonian system at a point of zero momentum. At such points the projection has rank zero and the resulting caustic has a corner. We use caustic equivalence of Lagrangian mappings to find a normal form for such a corner in 3 degrees of freedom.

Yeats as I new Him,In 1932, when Lady Gregory lay dying at Coole, Yeats wrote. to me to tell that she was reading my novel, ., on her death-bed; and he touched on synthesis only to reject it. ‘There are two Irelands,’ he wrote. His Ireland now, on his own admission, had nothing in common with that of Gaels or of Catholics.

Discussion of resultsThe problems of optics, acoustics and quantum mechanics, the theory of partial differential equations, probability theory and number theory lead to the need to study oscillatory integrals with large values of the parameter.
