Why is the apparent cosmological constant zero?,solutions of the Einstein equations with a large cosmological constant which appear nearly flat on large length scales but which are highly curved and topologically complicated on very small length scales. Estimates are made of the spectrum of these topological fluctuations and of their effects on the propagation of particles.

Stability properties of gravity theories,vided they occur within the event horizon intrinsic to this space. Outside the horizon an instability arises which signals the onset of Hawking radiation; it is shown to be universal to all systems. Semi-classical stability is also discussed for A > 0.

The numerical study of quantum chromodynamics,ke the confining force between a heavy quark-antiquark pair, the critical temperature of thermal quark liberation, or the mass gap for glue-ball excitations are reviewed first, within the pure gauge sector of the theory. The stochastic treatment of the complete fermionic problem is also described.

Radical unification,vcated where the fundamental symmetry group and the number of fundamental local fields is required to be minimal: The apparent higher symmetries and the larger number of phenomenological local fields here are effectively generated by the dynamics. In this context a U(1) ⊗ SU(2,loc) invariant theory

The numerical study of quantum chromodynamics,he detailed numerical study of Quantum Chromodynamics (QCD) with lattice regularization. Important results on non-perturbative physical quantities, like the confining force between a heavy quark-antiquark pair, the critical temperature of thermal quark liberation, or the mass gap for glue-ball excit

Why is the apparent cosmological constant zero?,would expect a large induced cosmological constant unless the various contributions from symmetry breaking, etc., were balanced against each other to better than 1 part in 10. It is suggested that this puzzle can be resolved by assuming that quantum state of the universe is not chosen at random but
