Sorry for the confusing title, but earlier when I was sipping some coffee I felt the heat emanating off of the liquid in the cup without touching the cup.
So it made me think, why don’t we treat heat sensitivity as a distinct sense to touch, taste, smell, sight, and hearing? I’d love to hear a catchier name for ‘temperature sensitivity’ for its distinct sense as well, since those other ones are less of a mouthful.
Thank you for coming to my shower thought!
But it is. Heat is nothing but very fast Brownian motion of particles. So the kind of very warm light touch comes from fast moving particles in a gas emanating from your cup of Joe and touching your upper lip.
