Dirac equation

The Dirac equation is an equation that helps us understand particles and particles behavior. It is written as a mathematical equation, and it tells us that particles can move in all directions, at different speeds, and with different energies. It also explains that particles can have different spins, which means that they can either spin like a top (clockwise) or counter-clockwise. This equation helps explain why particles behave the way that they do.
