What do they mean that energy is "quantized"? I am SICK of hearing that "energy comes in packets". I understand what they are saying, but I don't comprehend it, or understand the intuition behind it. Someone PLEASE clear this up for me. Obviously, I speak English, and I understand the words, but I don't comprehend the deep meaning or even the context to which this statement it applies to. Do they mean "energy come in packets" when light is absorbed by the electrons, or when the electrons give off energy after being hit by light? And WHY does energy come in packets? WTF, it doesn't make any sense. You can tell me you milked a dinosaur, but it makes absolutely no sense. SOMEONE CLEAR THIS UP!! THANK YOU IN ADVANCE!!
