This app is aimed at students who are looking for special relativity tasks with tips and detailed solutions.

There are tasks, tips and solutions on the following topics:
- Inertial system change
- time dilation
- length contraction
- Relativistic mass increase
- Relativity of simultaneity
- Application-oriented tasks such as muon decay and mass loss in fusion processes

With each processing, there are always new values ​​in the tasks, so that it is worth repeating the task.

For each task, tips and a theoretical part help with the processing. After a result has been entered, it is checked. If it is correct, points are awarded based on the level of difficulty. A sample solution can then also be viewed.

If the result obtained is incorrect, it is recommended to repeat the task.
