This paper is a celebration of the frontiers of science. Goodenough, the maestro who transformed energy usage and technology through the invention of the lithium ion battery, opens the programme, reflecting on the ultimate limits of battery technolog

The fully worked volume and shape of bars processed via equal channel angular extrusion through a 90 die and different multipass routes are reported. Results are given for square cross-section bars with an aspect ratio range of 3–20 for up to 16 pa

Recently, Ward [i] has developed a twistorial description of self-dual YangMills fields on pieces of conformally completed complex Minkowski space, CM. The solutions covering S4(conformally completed real Euclidean space) are the instantons of intere

A spacetime symmetry group is any group which may be used as the structure group for the tangent bundle to spacetime. I list many such groups and the corresponding principal bundles. The most familiar are: the Lorentz group = 0(3,1,8) which uses the

There are now many theories of gravity with a torsion field as well as the usual metric field. One of the arguments for allowing torsion is based upon a gauge theory analogy. The purpose of this paper is to clarify exactly which symmetries are being

We consider the problem of determining from intrinsic properties whether or not a given spacelike surface is a Cauchy surface. We present three results relevant to this question. First, we derive necessary and sufficient conditions for a compact surf

We find all torsion-free, spherically symmetric, vacuum solutions to the theory of gravity recently proposed by Hehl, Ne'eman, Nitsch, and von der Heyde. There are three classes of solutions: (A) the Schwarzschild metrics with arbitrary mass,M, and a

We generalize the Papapetrou equations by deriving propagation equations for the energy-momentum and angular momentum of a test body which has both elementary-particle spin and macroscopic rotation and which is moving in background metric and torsion
