Quantum Mechanics Quantum Mechanics By the 1960’s nearly 100 different particles had been discovered in the nucleus of the atom. By the 1960’s nearly 100 different particles had been discovered in the nucleus of the atom. Gell-Mann classified them using their electrical charge and “strangeness” in octets or “the eightfold way”.
