"It is shown that the Balmer terms of an atom with a single electron are yielded correctly by the new quantum mechanics and that the difficulties which arose in the old theory… disappear in the new theory." -Pauli, from the abstract
FIRST EDITION IN ORIGINAL WRAPPERS of Pauli's influential paper demonstrating the superiority and validity of the new quantum mechanics.
Following the development of quantum mechanics by Heisenberg, Born, and Jordan, "the first nontrivial and physically important application of quantum mechanics was made soon afterwards by Wolfgang Pauli [On the Hydrogen Spectrum from the Standpoint of the new Quantum Mechanics], who calculated the stationary energy values of the hydrogen atom by the matrix method and found complete agreement with Bohr's 1913 formulas. From this moment, there was no longer any doubt about the correctness of the theory among physicists" (Max Born, Physics in My Generation).
