# The 1925 Born and Jordan paper "on quantum mechanics"

@article{Fedak2009The1B, title={The 1925 Born and Jordan paper "on quantum mechanics"}, author={William A. Fedak and Jeffrey J. Prentis}, journal={American Journal of Physics}, year={2009}, volume={77}, pages={128-139} }

The 1925 paper “On quantum mechanics” by M. Born and P. Jordan, and the sequel “On quantum mechanics II” by M. Born, W. Heisenberg, and P. Jordan, developed Heisenberg’s pioneering theory into the first complete formulation of quantum mechanics. The Born and Jordan paper is the subject of the present article. This paper introduced matrices to physicists. We discuss the original postulates of quantum mechanics, present the two-part discovery of the law of commutation, and clarify the origin of…
