Statistical Physics is a branch of physics that uses statistics to explain how large groups of particles behave. Instead of focusing on individual particles, it looks at the collective behavior of many particles, such as atoms and molecules. This approach helps us understand phenomena like temperature, pressure, and phase transitions in materials, which are crucial for fields like thermodynamics and material science.
By applying statistical methods, scientists can predict the properties of systems in equilibrium and out of equilibrium. This field connects to various areas, including quantum mechanics and cosmology, helping us understand everything from the behavior of gases to the evolution of the universe.
