Second Eigenvalue Paper
Publishes the second paper in his wave-mechanics series and extends the new formalism beyond the first hydrogen calculations.

Wave and Matrix Mechanics Equivalence
Publishes a demonstration that his wave mechanics and Heisenberg's matrix mechanics are mathematically equivalent formulations of quantum theory.
