Inequalities in income and wealth distributions have been a permanent feature of the societies in any civilization, and are characterized by established and universal laws. The century old kinetic theory for the gases had long been identified as a possible tool to explore the origin of such inequalities. Such kinetic exchange formulations for social dynamics will be discussed and the recent developments will be indicated. Extensions of the kinetic theory to collective opinion formations in societies will also be discussed.
Finally a new measure, namely the k-index, for social inequality in income/wealth across population in societies and in citations earned by publications in universities/institutes, will be introduced and the common features in their observed properties will be discussed.
