This article explores the flavor mixing in particle physics, focusing on the CKM matrix for quarks and the neutrino mixing matrix. It discusses the observed quark masses, Cabibbo angle, unitarity triangle, and the connection to neutrino oscillations. The experiments of Fritzsch, Pontecorvo, Kamiokande, SNO, and the Nobel Prize-winning discoveries are also discussed.
