Massless or massive graviton?
We show that, in the application of Riemannian geometry to gravity, there exists a superpotentialV ij of the Riemann-Christoffel tensor which is the tensor generalization of Po...

The computer and the heat engine
Brillouin sees order as generated by tap** negentropy sources existing upstream, while Prigogine sees it as generated by dum** entropy downstream. Joining both ideas yields a picture of the computer closel...

Chapter
Relativity and Probability, Classical or Quantal
A ‘manifestly relativistic’ presentation of Laplace’s formalism of conditional probabilities is proposed, and its ‘correspondence’ with Dirac’s formalism of transition amplitudes is displayed. Algebraic revers...

On the zigzagging causility model of EPR correlations and on the interpretation of quantum mechanics
Being formalized inside the S-matrix scheme, the zigzagging causility model of EPR correlations has full Lorentz and CPT invariance. EPR correlations, proper or reversed, and Wheeler's smoky dragon metaphor ar...

On the zigzagging causality EPR model: Answer to Vigier and coworkers and to Sutherland
The concept of “propagation in time” of Vigier and co-workers (V et al.) implies the idea of a supertime; it is thus alien to most Minkowskian pictures and certainly to mine. From this stems much of Vet al.'s mis...

On Carmeli's exotic use of the Lorentz transformation and on the velocity composition approach to special relativity
As shown by Ramarkrishnan, the faithful map**, in the sense of Lie groups, of the real line onto the finite segment−1<u<+1 is u=tanh A, from which follows the “relativistic velocity composition law” w=(u+v)/(1+...

Bohr's discussion of the fourth uncertainty relation revisited
Bohr's 1930 derivation of the uncertainty relation c 2 δm δt≥h bears a close relationship to Einstein's 1913 derivation of the “gravitational redshift” via the “equivalence prin...

On some frequent but controversial statements concerning the Einstein-Podolsky-Rosen correlations
Quite often the compatibility of the EPR correlations with the relativity theory has been questioned; it has been stated that “the first in time of two correlated measurements instantaneously collapses the oth...

Relativistic dynamics of interacting point particles: Central position of the Wheeler-Feynman scheme
The Wheeler-Feynman (WF) relativistic theory of interacting point particles, generalized by acceptance of an arbitrary spacelike interaction, is shown to possess a privileged status, reminiscent of the “centra...

CPT Revisted: A Manifestly Covariant Presentation

Time Symmetry and Interpretation of Quantum Mechanics
There is something truly paradoxial in quantum mechanics. Physicists know well how to use it for explaining or predicting an ever-increasing harvest of phenomena, some of which are striking, even to the expert...

CPT Invariance as Basic for Interpreting Quantum Mechanics
This paper is an expanded version of one recently published in Foundations of Physics and is a continuation of previous works devoted to the EPR correlation.

MPT versus : A manifestly covariant presentation of motion reversal and particle-antiparticle exchange
We show that particle-antiparticle exchange and covariant motion reversal are two physically different aspects of the same mathematical transformation, either in the prequantal relativistic equation of motion ...
