The 13 pages that link to Matrix mechanics, each with the reason it gives.

• Quantum mechanicsRelated: It was the first complete modern formulation of quantum theory.

• Werner HeisenbergBroader topic: Heisenberg developed it in 1925 from relations among observable atomic transitions.

• Max BornBroader topic: Born recognized that Heisenberg’s multiplication rules were matrix algebra and developed the formulation with collaborators.

• Wolfgang PauliRelated: Pauli applied this framework to explain the hydrogen spectrum and electron structure.

• Old quantum theoryCompared with: It abandoned classical electron orbits instead of refining their quantization.

• Heisenberg uncertainty principleRelated: Its noncommuting quantities supplied the mathematical setting for Heisenberg's argument.

• Arnold SommerfeldCompared with: It replaced orbit-based old quantum theory with a framework that no longer depends on electron trajectories.

• Sommerfeld modelCompared with: It marked a decisive break from assigning electrons classical-like orbits.

• Wave mechanicsCompared with: It reached the same physical predictions through a formulation distinct from wavefunctions.

• Pascual JordanRelated: Jordan helped develop its algebraic formulation with Born and Heisenberg.

• BKS theoryRelated: Its emergence displaced the old-quantum-theory setting in which BKS had been proposed.

• History of quantum mechanicsBroader topic: Heisenberg, Born, and Jordan developed it as the first modern formulation.

• Mathematical formulation of quantum mechanicsBroader topic: It supplied an early algebraic route to the modern operator framework.
