Quantum mechanics is the branch of physics that studies the behavior of matter and energy in the presence of an observer. It is the foundation of modern physics and the theory of the wave-particle duality.

Quantum mechanics is based on the principles of quantum theory, which is the study of the behavior of matter and energy on the atomic and subatomic level. The name “quantum mechanics” was first used by the German physicist Max Planck in 1900.

In quantum mechanics, the behavior of particles is described by wavefunctions. These wavefunctions are used to calculate the probabilities of where a particle will be found.

The wavefunction of a particle is represented by the symbol Ψ (psi). The wavefunction contains information about the particle’s position, momentum, and energy.

The behavior of a particle is described by its wavefunction. The wavefunction is a mathematical function that tells us the probability of finding the particle in a particular place.

The wavefunction is represented by the symbol Ψ (psi). The wavefunction contains information about the particle’s position, momentum, and energy.

The wavefunction is a function of the position of the particle, represented by the symbol x. The wavefunction is also a function of time, represented by the symbol t.

The wavefunction is a solutions to the Schrödinger equation. This equation is a differential equation that describes the behavior of a particle in a potential field.

The Schrödinger equation is:

iℏ∂Ψ∂t=−ℏ2/2m∇2Ψ+V(x)Ψ

where:

i is the imaginary unit

ℏ is the reduced Planck constant

∂/∂t is the partial derivative with respect to time

∇2 is the Laplacian operator

m is the mass of the particle

V(x) is the potential energy of the particle
