Kompressoren und Druckluftwerkzeuge,lve displacement of the coordinate mesh through distances of order much smaller than ?. This will prove to be the basic reason why it makes good physical sense to speak of the distribution of energy, momentum, and stress carried by gravitational waves, and to assign to each contribution to the total

Accelerated Motion in Special Relativity,h’s surface). It maintains this acceleration for ?/4 years of proper time, after which it decelerates at the same rate and in the same direction for another ?/4 years of proper time. At the end of this time it is at rest with respect to the earth, but at a distance.

Realizations of Continuous Groups,of transformations that leave the forms of all dynamical equations invariant) from the Poincaré group to the group of general differentiable coordinate transformations, known to mathematicians as the .. It will be helpful, in introducing the formal apparatus of general relativity, to develop first a
