Our eyes see vibrations (photons). Our ears hear vibrations (fluid waves). Our noses smell molecules through a chemical interaction (vibrating atomic particles against olfactory receptor neurons) Our bodies feel through various receptors, but I'm not sure yet how these can be classified as vibrations.
Vibration size matters: smallest to largest:
- light (photons)
- volatile chemicals (molecule)
- fluid waves (air or liquid)
- touch (macro scale physical vibrations)
