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)
