Tidsutveckling, also known as time evolution, is a fundamental concept in physics and mathematics that describes how systems change over time. It is a central theme in various fields, including classical mechanics, quantum mechanics, and thermodynamics. In classical mechanics, the time evolution of a system is governed by Newton's laws of motion, which describe how forces acting on a body determine its acceleration and, consequently, its velocity and position over time. In quantum mechanics, the time evolution of a quantum system is described by the Schrödinger equation, which provides a mathematical framework for predicting the future state of a system given its current state.

In thermodynamics, time evolution is crucial for understanding processes such as heat transfer and entropy production.

The study of tidsutveckling also plays a significant role in fields such as cosmology and information theory.

Overall, tidsutveckling is a versatile and powerful concept that provides a unified framework for understanding the
