Also, found out recently that matter can act as a wave (or, de broglie waves as we call them in A levels for some reason) even with molecules with like 6000 atomic mass units. Given that these molecules, then, act differently depending on observation, kinda makes me feel weird about the way the molecules act in my own living tissue (I realise that there's no diffraction of the molecules in my body and hence no reason for any wavy-ness but still, interesting to think about.)
