## Resolving Paradoxes with Spacetime Diagrams

(Lecture: 10 minutes)

• spacetime diagrams for pole & barn and space war

See §8 of the text, especially §8.1 and §8.2.

### Reflections

Students should have just had the opportunity to resolve special relativity paradoxes using spacetime diagrams (in this activity). This lecture can be part of the wrapup for that activity, or serve as a good review at the next class meeting.
