We have invented devices to record what we can see, and devices to record what we can hear.
Why haven’t we invented something to record what we can smell?
How would this work if we did?
\[When I am travelling I really wish I could record the way things smell, because smell is so strongly evocative of memories and sensations.\]

When we were first learning about waves, my high school physics teacher said “the cool thing about sound waves is that you can hear me from the other side of the room without having to smell my stanky breath”
I can hear him from the other side of the room because the sound waves from his voice moves through the air, but his actual breath, the air molecules coming out of his mouth, stay pretty close to him, meaning only the people in the front row must suffer his “stanky breath”
