Oscillation of a rigid rod in the special relativity
F. M. Paiva, A. F. F. Teixeira
In the special relativity, a rigid rod slides upon itself, with one extremity oscillating harmonically. We discovered restrictions in the amplitude of the motion and in the length…
Algorithm for structure constants
F. M. Paiva, A. F. F. Teixeira
In a -dimensional Lie algebra, random numerical values are assigned by computer to especially selected structure constants. An algorithm is then created, which calculat…
La relativeca tempo -- II / The relativistic time -- II
F. M. Paiva, A. F. F. Teixeira
The theory of relativity showed that several Newtonian ideas about spacetime are imperfect. We present here some relativistic concepts related to these ideas: simultaneity of event…
Geodesics of simultaneity in Schwarzschild
F. M. Paiva, A. F. F. Teixeira
Geodesic of simultaneity is a spacelike geodesic in which every pair of neighbour events are simultaneous ($g_{0μ}\dd x^μ=0$). These geodesics are studied in the exterior region of…
Relativistic Doppler effect in a uniformly accelerated motion - III
F M Paiva, A F F Teixeira
In the context of special relativity, we describe with detail the Doppler effect between a light source at rest and an observer in linear motion and constant proper acceleration. T…
La relativeca tempo - I / The relativistic time - I
F. M. Paiva, A. F. F. Teixeira
The relativistic time is different from the Newtonian one. We revisit some of these differences in Doppler effect, twin paradox, rotation, rigid rod, and constant proper accelerati…
