Fundamental Concepts of Thermal Fluctuations

Thermal fluctuations are inherent variations in the energy of particles caused by their constant thermal motion. These fluctuations arise from fundamental thermodynamic principles, which govern how energy disperses at microscopic scales. Quantum effects also play a role, especially in nanoscale systems, by influencing particle behavior and energy states. As particles move randomly due to thermal energy, they create tiny, unpredictable variations in force and position.
