I tagged this as other because idk what branch of study this question would belong to.
But my question is. If I am I’m a room with a flower, I can smell the flower, how? Is the flower emitting gas? Some older posts that asked similar questions had comments saying something about volatile chemicals and particles but then didn’t explain what that meant or how particles still give off a smell.
So, what’s happening? I know our nose is essentially a chemical detector that sends signals to the brain. But what is it detecting and how does whatever it is get there in the first place?
The simplest way I can phrase this question, using the above example, would be: how does the smell from the flower get to me and what is it that actually gets to me?
If this doesn’t get auto-modded then thanks in advance
