TL;DR: Real Time Relativity as mentioned in this paper is a computer program that allows students to fly at relativistic speeds through a simulated world populated with planets, clocks, and buildings, with the goal of teaching special relativity to first year university students.
Abstract: Real Time Relativity is a computer program that lets students fly at relativistic speeds though a simulated world populated with planets, clocks, and buildings. The counterintuitive and spectacular optical effects of relativity are prominent, while systematic exploration of the simulation allows the user to discover relativistic effects such as length contraction and the relativity of simultaneity. We report on the physics and technology underpinning the simulation, and our experience using it for teaching special relativity to first year university students.

TL;DR: In this article, Carmona, Cortes, and Mercati extended the study of special relativity parametrized by a high-energy scale to second order, and obtained the coefficients of modified composition laws and Lorentz transformations at second order.
Abstract: The study of generic, nonlinear, deformations of special relativity parametrized by a high-energy scale $M$, which was carried out at first order in $1/M$ in J. M. Carmona, J. L. Cort\'es, and F. Mercati, Phys. Rev. D 86, 084032 (2012), is extended to second order. This can be done systematically through a (``generalized'') change of variables from momentum variables that transform linearly. We discuss the different perspectives on the meaning of the change of variables, obtain the coefficients of modified composition laws and Lorentz transformations at second order, and work out how $\ensuremath{\kappa}$-Poincar\'e, the most commonly used example in the literature, is reproduced as a particular case of the generic framework exposed here.

TL;DR: The Mansouri-Sexl and Sjodin point of view on clock synchronization in special relativity is maintained against various criticisms, taking into account also the recent view of stochastic electrodynamics as mentioned in this paper.
Abstract: The Mansouri-Sexl and Sjodin point of view on clock synchronization in special relativity is maintained against various criticisms, taking into account also the recent point of view of stochastic electrodynamics. Light speed invariance is also discussed in an intuitive way.
