Time, Length and Relativity

This article is a combination of two articles I wrote over 12 years ago, the first ‘Time and Relativity’ (sections Special Relativity to The Twin Paradox) appeared in Parabola in 1993 and the second ‘Length and Relativity’ (sections Measuring Length to The Magician’s Assistant Paradox) in 1994. I have put these two articles together for this special edition of Parabola, and added some updated references.
