So we have

[tex] \gamma \Delta \tau = \Delta t [/tex]

[tex] \gamma L = L_0[/tex]

So now from my lecture notes i have an observer Ha riding a broom at speed v, and a stationary observer He (so yeah if anybody has the book it is Hartle's Gravity book chapter 4 problem 19). In Ha's frame [itex] L_0 = v \Delta \tau [/itex] and in He's frame [itex] L = v \Delta t [/itex], so now when i substitute that into the equation for time dilation I will not get the result for length contraction. Am I misinterpreting the question or something... Ironically, the gravitational red-shift seems a easier from Hartle's explanation... Maybe I am just missing a [itex] \gamma [/itex] somwhere.

Thanks for any help.

Cheers,
