This discovery was very decisive in our understanding as well as formulating the current picture regarding the basic constituents of nature. I look back at the discovery, pointing out how unexpected, dramatic and significant it was.9 pages, To be Published in Nov. 10 Issue of Current Science (India)High Energy Physics - PhenomenologyHigh Energy Physics - ExperimentHigh Energy Physics - LatticeHigh Energy Physics - TheoryHistory and Philosophy of PhysicsThe November $J/Ψ$ Revolution: Twenty-Five Years Latertext
