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!

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...

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!

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!

So any idea how I could solve it?

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...

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?

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

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...

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...

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...

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...
