bensmb227 Posted November 12, 2015 Share Posted November 12, 2015 I was doing a problem in Griffith's "Intro to Electrodynamics" concerning a clairvoyante and her twin brother: Sophie Zabar, clairvoyante, cried out in pain at precisely the instant her twin brother, 500 km away, hit his thumb with a hammer. A skeptical scientist observed both events from an airplane traveling at 12c/13 to the right. Which event occurred first, according to the scientist? How much earlier was it? I did it using the Lorentz transformation. I don't know if I did it correctly or not so I was wondering if someone could help me make sure I did this correctly.

ydoaPs Posted November 12, 2015 Share Posted November 12, 2015 Well, what did you do and what answer did you get? Link to comment Share on other sites More sharing options...
bensmb227 Posted November 12, 2015 Author Share Posted November 12, 2015 Well I just set event B (for brother) as x(b)=0 and t(b)=0 and event S (Sophia) as x(s)=500 km and t(s)=0 and v(sc)=12c/13 for the scientist. I used the Lorentz transformation and found that the scientist "sees" event S at 541 km but 4 microseconds before the brother hurts his thumb.
