The assemblage of all the elements of impetus relating E to the assemblage of event-particles in the neighbourhood of E expresses the character of the field of activity in the neighbourhood of E. Where I differ from Einstein is that he conceives this quantity which I call the impetus as merely expressing the characters of the space and time to be adopted and thus ends by talking of the gravitational field expressing a curvature in the space-time manifold.
The space-time theory and the kinematics of the special theory of relativity were modelled on the Maxwell-Lorentz theory of the electromagnetic field. This theory therefore satisfies the conditions of the special theory of relativity, but when viewed from the latter it acquires a novel aspect.
"I know that all time is totally present, and that every moment has its own past-future line of event-sequence, and that all events in space-time occur according to maximum probability, but I just don't get this alternate probability stuff, at all. If something exists, it's because it's the maximum-probability effect of prior causes; why does anything else exist on any other time-line?"
The inside of the dome passed into another space-time continuum, even into another kind of space-time. The transposition would take half an hour; that seemed to be the time needed to build up and collapse the transposition field, regardless of the paratemporal distance covered.
Her simple direct sense of space-time and quantity unconsciously solves problems which cost their most famous mathematicians years of prolonged and laborious calculations requiring such intense mental application that they frequently forgot to breathe when engaged in them, and almost suffocated themselves in consequence.
This sense of the personal presence of an abiding Reality, fulfilling and transcending all our highest values, here in our space-time world of effort, may well be regarded as the differential mark of real spiritual experience, wherever found.
Sure enough, right in front of him, so close that he could smell the very heat of it, was the big tank with the red star on its turret. He cursed the sextet of sanctimonious double-crossers eight thousand miles and fifty years away in space-time.
According to this theory the metrical qualities of the continuum of space-time differ in the environment of different points of space-time, and are partly conditioned by the matter existing outside of the territory under consideration.
The whole object of these lectures has been to enforce the doctrine that space and time spring from a common root, and that the ultimate fact of experience is a space-time fact. But after all mankind does distinguish very sharply between space and time, and it is owing to this sharpness of distinction that the doctrine of these lectures is somewhat of a paradox.
When I say that it underlies the whole theory, I mean that in my opinion it ought to underlie it, though I may confess some doubts as to how far all expositions of the theory have really understood its implications and its premises. Our measurements when they are expressed in terms of an ideal accuracy are measurements which express properties of the space-time manifold.
