minus-squarebarsoap@lemm.eelinkfedilinkEnglisharrow-up7·edit-28 hours agoWe already can detect direction of infrared radiation, it’s called being warm on one side but not the other. Technically also possible by, say, lying half-way under a blanket and half-way not, but sensory integration takes care of the ambiguity. More interestingly, did you know we can see the polarisation of light?
