In the rod and hole paradox as described by Rindler (1961 Am. J. Phys. 29 365-6), a rigid rod moves at high speed over a table towards a hole of the same size. Observations from the inertial frames… Expand

Relativistic length contraction is revisited and a simple but new thought experiment is proposed in which an apparent asymmetric situation is developed between two different inertial frames regarding… Expand

Acceleration is not often considered in special relativity, but it can be, as in the following problem. A set of pointlike objects, each with initial velocity v0 = (u, 0, 0), initially moving… Expand

We present an apparent paradox within the special theory of relativity, involving a trolley with relativistic velocity and its rolling wheels. Two solutions are given, both making clear the physical… Expand

We provide three examples of the use of geometric reasoning with three-dimensional spacetime diagrams, rather than algebraic manipulations using three-dimensional Lorentz transformations, to analyze… Expand

Non-commutativity of the Einstein velocity addition, in case of non-collinear velocities, seemingly gives rise to a conflict with reciprocity principle. However, Thomas rotation comes at a rescue and… Expand

Three versions of the relativistic length contraction paradox are considered. A package of computer programs is used to make small animated graphics sequences that illustrate what happens in the… Expand

TLDR

REST-frame simulates a generalized world in Spacetime and gives the fine details implicit in the Special Theory of Relativity that have not yet been made apparent, disclosing the non-intuitive realm of Special Relativity.Expand
