How to start with advanced physics

[akashpandey]

I wanted to how to start with advance physics like qed, quantum mechanics, and advance mathematics, advance astrophysics.
Please friends help me because i am not gettiing to start with it and please suggest some courses

It's impossible to give meaningful advice without knowing which physics, mathematics, and astrophysics classes you've already taken..

First you meed the required mathematical background:

A good start for the physics would be Feynmans beautiful - Feynman's Lectures On Physics:

Then the life changing Landau Mechanics:

'If physicists could weep, they would weep over this book. The book is devastingly brief whilst deriving, in its few pages, all the great results of classical mechanics. Results that in other books take take up many more pages. I first came across Landau's mechanics many years ago as a brash undergrad. My prof at the time had given me this book but warned me that it's the kind of book that ages like wine. I've read this book several times since and I have found that indeed, each time is more rewarding than the last.The reason for the brevity is that, as pointed out by previous reviewers, Landau derives mechanics from symmetry. Historically, it was long after the main bulk of mechanics was developed that Emmy Noether proved that symmetries underly every important quantity in physics. So instead of starting from concrete mechanical case-studies and generalising to the formal machinery of the Hamilton equations, Landau starts out from the most generic symmetry and dervies the mechanics. The 2nd laws of mechanics, for example, is derived as a consequence of the uniqueness of trajectories in the Lagragian. For some, this may seem too "mathematical" but in reality, it is a sign of sophisitication in physics if one can identify the underlying symmetries in a mechanical system. Thus this book represents the height of theoretical sophistication in that symmetries are used to derive so many physical results.

If you want to know at the deepest level what modern physics is about - this is it, profound, deep and beautiful.

•The perimeter institute has a comprehensive program towards theoretical physics:
https://www.perimeterinstitute.ca/training/perimeter-scholars-international/lectures/2011/2012-psi-lectures
It starts with the basics mathematical skills ("front"), then moves on to the physics you mentioned ("core"), and beyond ("review", "exploration").

•I have done an "ordered" playlist of Susskind lecture which will takes you from classical mechanics to the standard model:
https://www.youtube.com/playlist?list=PL_-WaNODJdTo3Mkov2QlhZDs-ZieQ0sij
These lectures are a good complement to a more formal education and could help you find order in this mess.

•Also have a look at: http://www.staff.science.uu.nl/~gadda001/goodtheorist/ if you are looking for a clear path also.
"How to become a GOOD theoretical physicist".

•As to maths a good book for applied physicists:

Fascinating biography in the introduction!
