As Khandelwal points out in the Preface, the book comes at an opportune moment because we are moving, with the advent of Sarva Siksha Abhiyan, into a new phase of the partnership between civil society, government and nongovernment organisations in the field of education.

An attempt is made to tackle the problem on the basis of one fundamental system consisting of an electron and a proton, the Coulomb potential between which is regulated by temperature.

It is shown that ife is the magnitude of charge

Specifically, we attempt a microscopic ...

Such a potential, as was recently pointed out, may be relevant to the resolution of the long-standing problem of unidentified solar emission lines. We also eonsider in detail a predictive test of our approach, and draw attention to some related conceptual issues.

One-dimensional coupled integral equations are obtained for elastic nucleon-nucleon scattering which decouple in the I=0, S=O state. The theory, which contains no arbitrary parameters, predicts phase shifts which are in reasonable agreement with experiment for the higher partial waves. isotopic spin zero in order to reduce the number of coupled channels in the integral equations, and finally solve the integral equations numerically for elastic nucleon-nucleon scattering in the I=5=0 state, the low-encrgy pion-nucleon interaction being approximated by a suitably chosen separable potential.
