The Schrödinger Equation is a fundamental equation in quantum mechanics that describes how the quantum state of a physical system changes over time.
Proposed by Austrian physicist Erwin Schrödinger in 1925, this equation revolutionized our understanding of the behavior of particles at the microscopic level.
It is a cornerstone of quantum mechanics, providing a mathematical framework for predicting the behavior of particles such as electrons, atoms, and molecules.
The equation is written as:
\[i\hbar\frac{\partial}{\partial t}\Psi(\mathbf{r},t) = \hat{H}\Psi(\mathbf{r},t)\]
Where \(i\) is the imaginary unit, \(\hbar\) is the reduced Planck constant, \(\Psi\) is the wave function representing the quantum state of the system, \(\mathbf{r}\) represents spatial coordinates, \(t\) represents time, and \(\hat{H}\) is the Hamiltonian operator, which represents the total energy of the system.
Solving the Schrödinger Equation yields the wave function \(\Psi\), which contains all the information about the system's possible states and their probabilities.
This allows physicists to predict the behavior of quantum systems with remarkable accuracy, from the behavior of electrons in atoms to the properties of complex molecules.
