The Minkowski Diagram model displays the spacetime diagrams for two inertial observers. One or two events may be displayed and moved with the mouse. Optionally, the corresponding light cones may be shown, as well as the simultaneity lines in both reference frames. The spacetime interval is automatically computed. The simulation may be used to discuss simultaneity and causality in special relativity. You can modify this simulation if you have Ejs installed by right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item.
The Minkowski Diagram model was created using the Easy Java Simulations (Ejs) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_ehu_special_relativity_minkowski.jar file will run the program if Java is installed.
Please note that this resource requires at least version 1.5 of Java (JRE).
