Quantum-Theoretical Re-Interpretation of Kinematic and Mechanical Relations | W. Heisenberg, 1925

This paper is the original paper written by W. Heisenberg in July 1925 which is considered as the birth of Quantum Mechanics translated in English (ref: Sources of Quantum Mechanics, Van Der Wearden). There is also a paper written by M. Khorrami explaining this paper with modern notation which I’ve found interesting.
