    Introductory Special Relativity Problem

    In my solution before these are the two events: Event 1: Zero of spacetime in all frames i.e when the rocket just starts Event 2: The clock passing by Earth Can you tell me what's wrong? Thanks!

    Introductory Special Relativity Problem

    Okay I'm stuck again :P Variables followed by '1' are in Earth's frame, those followed by '2' are in Z's frame. x1^2 - t1^2 = x2^2 - t2^2 x2 = 0 because the clock is at Earth when it time is recorded and initial value = 0 i.e when the rocket starts. x1/t1 = v = -0.75 because Z's frame...

    Introductory Special Relativity Problem

    Ohhh! synchronized means the clocks read the same value! I thought it means the clocks run at the same rate which would mean the velocities of the frames are equal. So 14.67 = time in James' rocket = time in Z's!

    Introductory Special Relativity Problem

    I'm sorry I don't quite follow how James' frame before his direction change can be related to the frame after the change (i.e Z's frame) ... Also I mentioned my attempt at the solution. Could you spot anything wrong in that? Thanks!

    Introductory Special Relativity Problem

    So any idea how I could solve it?

    Introductory Special Relativity Problem

    Yeah that was a part of the question I got. But Z's frame moves in a direction opposite to that of James' when he travels from Earth to Sirius. Anyway here's what I did for that part: Here variables followed by '1' correspond to the Earth frame and those by '2' correspond to James' frame when...

    Introductory Special Relativity Problem

    Oh crap! There's a mistake. All variables followed by '1' are in Earth's frame. I think it should make sense now! Thanks. Is there a way I can edit the original post?

    Introductory Special Relativity Problem

    Hey! t1 = 8.7/0.75 years(probably should've mentioned the "years" part) is the time taken by the rocket to reach Sirius in the Earth frame. Thanks

    Electrical Engineering : Fields of study and work.Are you enjoying it?

    I came across a few Biomed companies in the news. They and a few others (related to defence etc) were in countries other than my own (like USA and Canada). I hear its near impossible to get employed there, especially if its defence or space related because those are government related (NASA...

    Introductory Special Relativity Problem

    Homework Statement I was reading from Spacetime Physics (2nd Edition) by Taylor and Wheeler when I stumbled upon this problem I couldn't get right. Here's the gist of the part of the problem that I couldn't solve: Assume Earth is the rest frame of reference and that the planet Sirius is in...

    Electrical Engineering : Fields of study and work.Are you enjoying it?

    Hi, I'm done with my second year of electrical engineering and am interning at nVidia. So far all I see is people in cubicles debugging code and compiling kernels. Of course there's nothing wrong with it but I was disappointed because I chose electrical over computer science in the hope of...

    D Alembert's Principle: Dependence of kinetic energy on generalized coordinates.

    Hey! I was reading Goldestein's book on classical mechanics and I came across this (Page 20 3rd Edition): "Note that in a system of Cartesian coordinates the partial derivative of T with respect to qj vanishes. Thus, speaking in the language of differential geometry, this term arises...
