Matrixmechanik
Matrixmechanik is a fundamental formulation of quantum mechanics developed by Werner Heisenberg, Max Born, and Pascual Jordan in 1925. It represents a radical departure from classical physics by describing physical quantities, such as position and momentum, not as continuous variables but as matrices. These matrices are infinite-dimensional operators that act on quantum states.
In matrix mechanics, the state of a quantum system is not represented by a wave function as
A key feature of matrix mechanics is its inherent non-commutativity. For instance, the position and momentum
Matrix mechanics and Schrödinger's wave mechanics are mathematically equivalent, both providing a complete and consistent description
