Space Time II 50f
Space/time/space-time continuum/RT/Russell: new determination of time and location are no longer independent of one another - if you change the type of localization, you probably also change the time interval between two events - or if you change the type of time determination, you might change the spatial distance - there is no universal time any more - only when two bodies are at rest, their proper times match. - Def clearly earlier: is an event if it can affect another - (effect). - Graphic/(s): two circles around two dots - points of intersection: at the same time - for someone in the intersection: Both events were observed - depending on whether closer to A or B, the corresponding event is observed earlier.
II 68
Def spatio-temporal distance/SR/Russell: you take the square of the distance between two events and the square of the distance that light travels in the time between the two events - then subtract the smaller of these numbers from the larger one and defins the result as the square of the distance between the two events - this distance is the same for all observers and represents a truw physical relationship between the two events, which is not the case in temporal and spatial distance - AR: the concept of distance must be further generalized.
II 115
Space-time/time/momentum/mass/RT/Russell: if we replace time with space-time, we note that the measured mass (as opposed to the rest mass) is a quantity of the same kind as the momentum in a given direction: you could call it momentum of the time direction - the measured mass is obtained by multiplying the invariant mass with the time that elapses when covering the distance. - Momentum: is obtained by multiplying the invariant mass with the distance.
