      Hi Rossy 🙂

      There isn’t really a difference! They look at the same thing. So the theory says that small things behave in a different way to big things, so it looks at things at atomic levels and very small particles and says they behave in a certain way. They can’t be explained by classical physics (physics of things as we know them in large scale).
      Quantum physics takes this theory and uses it and applies it to small particles to study what they do. So quantum physics is called that because it uses quantum theory to look at very small things.

      Make sense?
