Physics
Vibrational Energy
Quick fact
Even at absolute zero, molecules retain a minimum amount of vibrational energy called zero-point energy, a purely quantum mechanical effect.
Why this is interesting
Ever wonder why a hot object glows red, or how a microwave heats food without touching it? The answer lies in tiny, constant vibrations—the hidden dance of atoms that holds the key to temperature, light, and even the warmth of a summer day.
