Thanks for interacting and being thoughtful about 'me being a bit snobbish'😂,I will check the books out.

Thanks for suggestion,but I see both Gould and Jaeger are from engineering perspective while I am inclined towards a more 'physics'(theoretical) approach.And I personally do not think it would be quite helpful to jump into Landau directly.

TL;DR Summary: Pretty much confused about an advanced elasticity book.Resource recommendation is asked. My last semester in freshman year of bs physics included a chapter on elasticity,it was not at the advanced level and by advanced level i mean atleast the tensor stuff.Well,I want to read...

Ok, I get it. But does that mean someone at my level should not touch Goldstein? If so then I will be acting more carefully from next time and save everyone's time(including mine) from the next time.

I can do this, but I do not really know how to write math with latex yet, so I can describe by words Sin(54)-Sin(18)=2Cos(36)Sin(18) =2Cos(36)Sin(36)/2Cos(18) =Sin(72)/2Sin(72) =1/2 But I do not understand what does that prove.

I would not make you type again the "plenty of advice", and not "disregard"ing that "plenty of advice", I would say: a)Reviewing what I learned in high school, it was just newtonian mechanics, shm and waves, electrostatics, electrodynamics, ray and wave optics, some modern physics including...

Well, the point where I got stuck in Goldstein's book is where he just derives the D'Alembert's principle Eqn 1.52, he says:"Note that in system of Cartesian co-ordinates the partial derivative of T with respect to q^j vanishes. Thus speaking in the language of differential geometry, the term...

No sir. I just wrote what I thought.

I am self studying Goldstein first chapter "A survey on the elementary principles", so far I have been enjoying it, sometimes he skips some lines while deriving a principle or so, therefore sometimes I get to PSE or Physics Forums to know the things I lack understanding in. What are your...

Yeah the questions got no replies because I accidentally framed such a big paragraph.

I am intending to join an undergrad course in physics(actually it is an integrated masters course equivalent to bs+ms) in 1-1.5 months. The thing is, in order to take a dive into more advanced stuff during my course, I am currently studying some of the stuff that will be taught in the first...

That was quite insightful, thank you.

@jtbell I am from India

TL;DR Summary: Here I am asking for some opinions and recommendations for mathematically rigorous books that should be taken as an interested physics student. I know the question is quite subjective but any insightful answer is appreciated. I am willing to join undergraduate physics classes...
