| | The case against a perpetual NPT 1
The conference of the members of the
Nuclear Non-Proliferation Treaty must strive to continue the treaty, but not to
make it perpetual; the world will need regular reminders of the hazards of
proliferation for decades to come.

| | Towards unequal partition of energy? 11
A tantalizing simulation of simple colliding
particles in one dimension reveals a clumping tendency in which energy is by no
means equally shared among them. The bearing of this on three-dimensional
hydrodynamics is another matter.

| | Seismic and geochemical evidence for large-scale mantle upwelling beneath
the eastern Atlantic and western and central Europe 34
Seismic tomography and the isotope geochemistry of Cenozoic
volcanic rocks suggest the existence of a large, sheet-like region of upwelling
in the upper mantle which extends from the eastern Atlantic Ocean to central
Europe and the western Mediterranean. A belt of extension and rifting in the
latter two areas appears to lie above the intersection of the centre of the
upwelling region with the base of the lithosphere. Lead, strontium and
neodymium isotope data for all three regions converge on a restricted
composition, inferred to be that of the upwelling mantle.
