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.

Metastability
Metastability denotes a system’s stable state that is not its most energetically optimal. These transient states can endure for significant durations and are observed across various domains, influencing both natural and technological behaviors.

Ergodicity
Originating in thermodynamics, the concept of ergodicity posits that systems, over extended periods, equally traverse every possible state. Beyond its foundational role in physics, ergodicity impacts disciplines from mathematics to economics, shaping understanding of prolonged system dynamics.

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.

Conservation Principle
The Principle of Conservation in science posits that certain properties of a closed system, such as energy or mass, remain constant over time, irrespective of internal processes. This fundamental concept underpins our understanding of many physical, chemical, biological, and environmental interactions.
