Russell, Bertrand. ABC der Relativitätstheorie, Frankfurt, 1989
II 38
Time/Concurrence/Relativity Theory/Russell: concurrence only has a meaning with respect to an observer. - Each clock measures its own time correctly. - The own time does not provide a measure of bodies moving relative to it. - From the perspective of accelerated electrons their own mass remains equal. - For them, the observer becomes thicker or thinner. - Russell: We must look at the distances between events, not between bodies.
>Relativity theory, >Observation.
II 55
Concurrence/Russell: comes into play in relation with congruence.
>Simultaneity.
II 55f
Time/Place/Relativity Theory/Russell: There is no same time for different observers. - That is why we always need to provide the time and place for an event. - Event instead of body: is an observed body.
II 65
Time/Time Dilatation/Relativity Theory/Special Relativity Theory/Russell: events towards which the traveler is moving seem to him like things of the past. - The events lying behind him seem to be in the future. - For the observer standing on the railway line they seem to be in the present.
II 105
Power/Relativity Theory/Russell: is no longer a fundamental concept of dynamics - more like "sunrise". The same force applied to a heavy body does not cause as much acceleration as a lighter one.
>Meaning change, >Theory change, >Absoluteness.
II 121
"During"/Relativity Theory/Physics/Logical Form/Russell: multiplication with time. - ((s) Division: E.g. speed: would not be referred to as "during" - In contrast, "during": E.g. Maintained speed times a time - result: distance traveled -> acceleration.
sec²: here multiplication comes in again. - the fact that a particle follows a geodesic is then the "principle of least effect".
