My purpose is to discuss some disagreements found in the literature on electromagnetic theory, bearing on how the fields should be transformed under improper transformations of spatial coordinates and time reversals. I hope to encourage workers to el

My aim is to explore some ideas about the foundations of electromagnetic theory for elastic materials and to suggest some ways of assessing theories of this kind. I will describe some old ideas that seem to have been forgotten, about forces exerted b

I develop a variational principle introduced in [2] for electromagnetic elastic bodies and discuss its consequences. Formulae for stress tensors and configurational stresses are derived by energy minimization.

Various kinds of crystals are grown by nature in multiply twinned configurations called cyclic twins. Here, for the first time, I will use twinning equations to analyze some representative examples of these. Generally, these can be free of shear stre

Several writers have proposed quasistatic theories of moving magnetized bodies, neglecting the induced electric fields. Obviously, this excludes the possibility of analyzing radiation, which I can tolerate. However, time independent fields have been

Essentially, this is a critique of static theories covering magnetic effects and elastic deformations. For this, I just use general ideas of continuum theory and common ideas from the calculus of variations as it relates to energy minimization. I obt

Typically, solutions of twinning equations for crystals require the interface to be a definite plane and are only applicable to a limited set of lattice vectors. To be presented are solutions for which the possible interfaces form an infinite set, an

Complications encountered in the α ↔ β phase transition in quartz have long puzzled workers. Experts now believe that this involves a third intermediate (incommensurate) phase. A theory of this has been proposed and favorable comments about it ha

I study the structure of Pitteri neighborhoods centered at hexagonal close-packed configurations of monatomic crystals using my previously introduced X-ray theory. The theory is generalized to cover some effects of magnetism. I give an alternative fo

Twinning equations associated with the X-ray theory are conceptually different from others in the literature, in that they are not linked to deformation. Despite this, they have been applied to deformation twins, as well as to growth twins, with some
