How do you know if something is boiling or simmering?

But for most purposes, a simmer is the stage when the water is in motion but almost no bubbles break the surface; they’re trying to, but the water’s surface tension holds them in place. Boiling, though, refers to liquid that’s in full motion, with bubbles rapidly rising to the surface.

Do little bubbles count as boiling?
