A First Course in String Theory
Consider a two-dimensional world with coordinates and .
A boost with velocity parameter along the axis is described by the first two equations in (2.36). We want to understand the two-dimensional space that emerges if we identify
We are identifying spacetime points whose coordinates are related by a boost!
(a) Use the result of Problem 2.2, part (a), to recast (1) as
, where .
