Scent

It's really cold, so I had to put on my winter jumper. Putting on old clothes carries the scent from previous times, and this scent made me very happy. It was like holding a loved one I hadn't seen for a long time very close. Lovely memories and sensations came flooding back. Smell is such a powerful sense - it goes straight to the heart. 

It turns out that the mechanics of smell are quantum. Scent resonates at a molecular level with our physiology. It sings, and we recognise the song. In order for it to sing, it must have some kind of dimensional attributes. Connoisseurs talk of "notes" and I'm sure that's not a coincidence. We certainly detect signals in the olfactory process. My jumper smells a bit fruity... But the notes of smell ring through the noise of everything else. And presumably there are emergent constraints in the quantum smell process which lead to the focus on particular notes and not others. Finally there's the set of expectations and associations with the smell. Flowers, hormones, sweetness, joy and love... These are not separable processes.. they happen together.
