Kaluza-Klein theory and general relativity
The relationship between Kaluza-Klein theory and general relativity is a foundational aspect of the former. Kaluza-Klein theory extends general relativity by incorporating additional dimensions beyond the familiar four-dimensional spacetime. Here…
Why Hilbert Space in Quantum Mechanics?
Heisenberg's matrix mechanics and Schrödinger's wave mechanics - have a common underlying mathematical structure. That common structure is Hilbert space. These two theories are said to be isomorphic. If you…
