  • Principle of Least Action

    Principle of Least Action

    In physics, the Principle of Least Action serves as a unifying framework that dictates a system’s dynamics through the minimization or stabilization of a specific integral, known as action. This principle offers valuable insights across various fields within physics.

  • Renormalization


    Addressing the challenge of infinities in quantum calculations, renormalization refines initial parameters to ensure tangible results. It traces its origins to quantum electrodynamics and underpins the success and accuracy of the Standard Model in particle physics.
