I want put a fundamental question on the collective dynamics in the fluids of electrically charged particles. What is the basic physics responsible behind the origin of viscoelasticity in the Coulombic fluids?
It is often felt that "Happiness" is a temporary feature; whereas, "Unhappiness" is a not-so-temporary feature of life. A natural philosophical question now arises towards "Happy life". How can...
