Special Relativity, Lecture 6: The Twin Paradox - 3rd Year Student Lecture

In the final lecture of six lectures we are showing from Fernando Alday's 'Special Relativity' third year course, we explain why the twin paradox is not really a paradox, and we work out how to add velocities.

Third and fourth year lectures are followed by classes.
