most probably, I'm going for CAT(mba), or a job, if i find a good one, will study physics by myself as a hobby, or a 'passion', if i use a better word, as i think i can do that better than when studying for a grade or something. Also hate the idea of somebody else sitting on my head and telling...

I am from India, wanted to pursue physics when was in high school, still want it, I got admission into a top technical university (IIT Delhi) and took up a 4 year B.Tech in engineering physics because i just 'thought' that the word physics would mean i would be studying physics, the science...

this has been quite an 'enlightening' thread (though many on this site are, this one has a 'personal' touch) a question, after a PhD, if you leave the 'formal' academic field, can you still publish papers on stuff u like if they are worth their salt?

thnx frameDragger,

what is 'a' (i.e. the small a) , is it the accn of the body takin it as a const its already pretty complicated

what is 'a' (i.e. the small a) , is it the accn of the body

If that is life, it sucks big time, doesn't it? btw i too have similar feelings/situation as the creator of the topic, but i don't know what i am going to do, i like studying physics a lot, but what and the way they teach in semesters is garbagety. Is it everywhere like that? Do u have to all...

yeah i get that, but if u convert the expression for 4-accn in O to that in MCRF, your time component becomes 0 in that expression and all u are left with is the spatial part which can be put into an equation like this (gamma^3)(v(dot))= alpha (this is the same equation u get when u do it other...

for the first point, Even if the accn has ay and az components, we can take our x, or y or z axis to point in the direction in which accn points. just like rotation of x-y plane to desired direction changes nothing in z-axis, rotation of x-y-z space to suit my purpose won't change anything in t...

i too would have preferred working with general coordinates but first i think i need to learn how to derive lorentz transformation for arbitrary velocity(all 3 components), can u recommend something? but coming to how i worked on things, in the problem it is mentioned that body starts from...

i am not clear which argument are you talking about. can you please explain it

in MCRF of a body, the four accn has only spatial components. now since the body begins from rest in our frame, and since the four accn is of a constant direction and magnitude, we can take our x-axis to be along the direction of the four accn when MCRF of body is same as our frame. So now the...

thnx, got it, was pretty easy though, no need of squaring and all.

i took the A.A= (alpha)^2 where A is the four acceleration and the value of A which i took was same as that u have written. also, i took d(gamma)/dt = ((gamma)^3)(v)(dv/dt) [which is obvious]also if i wasn't clear earlier, A.A = (alpha)^2 was the exact statement made in the book, i.e 'schutz...

Homework Statement a particle is under constant 4 acceleration (given of const magnitude(alpha) and direction), the particle starts from rest in a frame O, i have to find the speed of body after time t in O Homework Equations well can't give any very important equation, i guess this is...
