My Organic Chemistry professor once said, “Atoms get into excited state. But eventually, they will go back to their ground state. Have you ever been excited for 30 days straight?”
According to Wikipedia, quantum mechanics says that an excited state is having an energy above the absolute minimum.The lifetime of an excited state is usually short, and this return to a lower energy level is called decay. There is a long-lived excited state though, referred to as metastable.
This excited state thing may indeed be applicable human beings, as the human body is a system itself. Continue reading “Atoms Get Excited Only For a While”
