Nice quote from Einstein describing fundamental science discovery: “highest form of musicality”

““That [the] insecure and contradictory foundation [of Bohr’s quantum hypotheses],” Einstein would say, “was sufficient to enable a man of Bohr’s unique instinct and perceptiveness to discover the major laws of spectral lines and of the electron shells of the atom as well as their significance for chemistry appeared to me like a miracle. . . . This is the highest form of musicality in the sphere of thought.”” (Richard Rhodes, The Making of the Atomic Bomb)
