Blackbody Radiation and Planck`s Hypothesis of Quantized Energy
... This is even true if we have a particle beam so weak that only one particle is present at a time – we still see the diffraction pattern produced by constructive and destructive interference. Also, as the diffraction pattern builds, we cannot predict where any particular particle will land, although ...

3.5 Why does a quantum mechanic state change?
... • The thermal energy of the system itself causes an excited state since only at T = 0 the Fermi energy describes the highest occupied energy state. We find a dynamic equilibrium between states steadily increasing or decreasing the energy. • Surfaces and defects in a crystal change the Hamiltonian of ...
