"Technically, chemistry is the study of matter. But I prefer to see it as the study of change…
Electrons, they change their energy levels. Molecules change their bonds. 
Elements, they combine and change into compounds. 
Well, that’s all of life, right?…
It’s the constant, it’s the cycle. It’s solution, dissolution, just over and over and over. 
It is growth, then decay, then transformation. It is fascinating, really."
Walter White
