Russell, Bertrand Books on Amazon: Bertrand Russell |
Space | Course book 8 IV 12 Weierstraß/Russell: banished the infinitesimal variable from mathematics - VsZenon: error: to think that the world must always be the same because there is no state of change - without infinitesimal variables: time: no more "next moment" - no immediate result of two moments in between ever more M - Space: dito: always further divisible B. Russell, ABC of Relativity Theory 46 Def "space-like"/Russell: Two events are space-like if it is impossible for a body to move fast enoug to be present at both events -" but he can be "halfway" and perceive both as happening at the same time - Def "time-like"/Russell: Two events are time-like if it is possible for a physical body to be present at both events -" borderline case: E.g. two events as part of a light beam or - E.g. an event = perception of the other event: then distance 0 - Def distance/Russell: is a physical fact which is part of the events and does not depend on the circumstances of observer - neglecting gravitation, one can apply the SR. Then the distance between two events can be calculated if one knows the spatial and temporal distance, measured by an arbitrary observer. |
