@tmblnd1325194EK physical padle 4 books ka phaida hi nahi.
@tmblnd1325194I think there wont be any ready made solution for this question on books. You have to split the Ecosystem into its components and answer in that prespective.
@tmblnd1325194Just read Savindra singh physical. That itself would be enough for conceptual understanding. No need to go deep with part books.
