These are the author's lectures at the 1992 Les Houches Summer School, "Gravitation and Quantizations". They develop a generalized sum-over-histories quantum mechanics for quantum cosmology that does not require either a preferred notion of time or a definition of measurement. The "post-Everett" quantum mechanics of closed systems is reviewed. Generalized quantum theories are defined by three elements (1) the set of fine-grained histories of the closed system which are its most refined possible… 
Generalizing Quantum Mechanics for Quantum Spacetime
Familiar textbook quantum mechanics assumes a fixed background spacetime to define states on spacelike surfaces and their unitary evolution between them. Quantum theory has changed as our conceptions

A ug 2 00 5 A Spacetime Path Formalism for Relativistic Quantum Mechanics
Quantum field theory is the usual solution to the problems inherent in melding quantum mechanics with special relativity. However, there has also been significant literature on an alternate
Quantum logic and the histories approach to quantum theory
An extensive analysis is made of the Gell‐Mann and Hartle axioms for a generalized ‘histories’ approach to quantum theory. Emphasis is placed on finding analogs of the lattice structure employed in
Quantum universe: a particle moving or a wave propagating?
The wave-particle description of quantum mechanics is briefly reviewed to set an 1 analogy between the quantum mechanics of particles and fields and quantum cosmology. It is 2 shown that quantum
Generalized Quantum Mechanics
It used to be that the term ‘quantum mechanics’ referred to one thing — the nonrelativistic (Copenhagen) quantum mechanics of laboratory measurement situations. There was only one formulation of
The regular histories formulation of quantum theory
It can be argued that RH compares favourably with other proposed interpretations of quantum mechanics in that it resolves the measurement problem while retaining an essentially classical worldview without parallel universes, a framework-dependent reality or action-at-a-distance.
Quantum Theory Without Hilbert Spaces
Quantum theory does not only predict probabilities, but also relative phases for any experiment, that involves measurements of an ensemble of systems at different moments of time. We argue, that any
Spacetime states and covariant quantum theory
In it's usual presentation, classical mechanics appears to give time a very special role. But it is well known that mechanics can be formulated so as to treat the time variable on the same footing as


Classical equations for quantum systems.
This work investigates the requirements for coarse grainings to yield decoherent sets of histories that are quasiclassical, i.e., such that the individual histories obey, with high probability, effective classical equations of motion interrupted continually by small fluctuations and occasionally by large ones.
Sum-over-histories origin of the composition laws of relativistic quantum mechanics and quantum cosmology.
The principal technical aim of this paper is to show that the relativistic composition law may, in fact, be derived directly from a sum over histories by partitioning the paths according to their first crossing position of an intermediate surface.

Operator ordering in theories subject to constraints of the gravitational type
Covariant operator realization of Dirac constraints is proposed in theories of the gravitational type, subject to Hamiltonian and momentum constraints, and generalizes to the level of the exact theory the recently proposed semiclassical algorithms in models with arbitrary first-class constraints.

Using a combination of x-ray diffraction and electron diffraction, the scientists produced a three-dimensional map of the hybridized "orbital hole" bonding copper with neighboring oxygen atoms in cuprite (Cu2O).
