All objects in 4D spacetime may in principle travel on null paths in a 5D mani-fold. We use this, together with a change in the extra coordinate and the signature of the metric, to construct a simple model of a classical universe and a quantized particle. There are notable implications for the Weak Equivalence Principle and the cosmological constant, and for astrophysics. 

Paul Wesson and Space-Time-Matter Theory

A short scientific biography is given of physicist Paul Wesson (1949-2015), who published over 300 works encompassing the fields of astrobiology, astrophysics, geophysics, cosmology, and relativity;

Physics and the Pythagorean Theorem

Pythagoras' theorem lies at the heart of physics as well as mathematics, yet its historical origins are obscure. We highlight a purely pictorial, gestalt-like proof that may have originated during



Concepts of Mass in Contemporary Physics and Philosophy

The Mass-Energy Relation and the Principle of Equivalence: The Nature of Mass 143 Index 169 shows how the relationship between mass and energy has changed since the time of Galileo.
