Eclipses of the Starsne such humble idea eventually became a great scientific achievement—after much resistance and reluctance due to elitist attitudes towards science. It is a story about imagination and individual generosity, but also about science as a social enterprise and the role of contingency in its development.

Timekeeping in an Expanding Universeon for compact sources of the gravitational and electromagnetic fields. The results show that such a model is only approximately an ‘ideal’ clock and differs from one by terms of the order of (clock period/Hubble time).

Quasi-Local Energye quasi-local energy as a two-surface integral over the convergence of the past cone minus a similar integral over a surface in Minkowski space. This definition is suggested by the results of an analysis at null infinity.

The Prehistory of Relativitywho most probably took the idea from the work of John Michell. Actually, I showed how John Michell constructed, essentially in his 1784 article (.), the Newtonian theory of the action of gravitation on light. Elsewhere I showed how Michell’s ideas are deeply rooted in Newton’s theories: not only his

The Trouton Experiment, , = ,,, and a Slice of Minkowski Space-Timexperiment was to detect the earth’s presumed motion through the ether, the 19th-century medium thought to carry light waves and electric and magnetic fields. The experiment was unusual in that, unlike most of these so-called ether drift experiments, it was not an experiment in optics.. Trouton tried

The N-Stein Family880 but before the advent of general relativity, Newstein brooded on the equality of inertial and gravitational mass. Through an ingenious thought experiment—the Newstein elevator—he hit upon the idea of an essential unity of gravitation and inertia. This was expressed in the indistinguishability of
