I have a question about difference between physical observables and eigenstates in quantum mechanics it is postulated in Quantum Mechanics that physical observable in Classical Mechanics are represented by linear operators the state of the particle was represented by a curve in phase space determined by generalized position and momentum but in Quantum Mechanics it is represented by a vector in Hilbert space and if we measure the physical observable of the particle, the previous state of the particle once...

A. Describe specifically two major differences between quantum mechanics and classical mechanics. B. How does the correspondence principle link quantum mechanics and classical mechanics? C. Why is it still accurate to use classical mechanics for human size objects? That is, why are our wave like properties not observed?

Discuss TWO of the following approximation methods in quantum mechanics. Explain the types of problems to which the approximation methods can be applied, how the basic theory is developed, and how they are applied in practice. Include some mathematical details in your answer. (i) The Hartree theory of atoms and ions. (ii) The variational method. (iii) Non degenerate and degenerate perturbation theory.
