I knew that energy was transformed but not transferred but it was interesting to hear the story that there is no such thinkg as energy independent from matter and that energy is just a way of describing the organization of matter. I found this to be really interesting because I never really realized it before.

I found it cool how we were able to answer the age old question 'if a tree falls and no one is around to hear, does it still make a sound" just by realizing that certain molecules, in this case soundwaves, are not effective unless they interact with other molecules, i.e. the ear. From this I learned that vibrations turns into sound only when it hits the ear, which is an interesting thing to think about.
