What is Quantum Physics?


Quantum physics is a branch of science that deals with discrete, indivisible units of energy called quanta as described by the Quantum Theory. There are five main ideas represented in Quantum Theory:

1.Energy is not continuous, but comes in small but discrete units.
2.The elementary particles behave both like particles and like waves.
3.The movement of these particles is inherently random.
4.It is physically impossible to know both the position and the momentum of a particle at the same time. The more precisely one is known, the less precise the measurement of the other is.
5.The atomic world is nothing like the world we live in.
