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?
\[When I am travelling I really wish I could record the way things smell, because smell is so strongly evocative of memories and sensations.\]

Seeing works from light hitting your eye. We can use light hitting photo paper to create the same image.
Smelling comes from volatile molecules entering your nose. To recreate it, you need to recreate the exact same molecules in the exact same proportions and then release them into your nose. That means you’d need a machine which contains *every molecule that exists* in *infinite amounts*.
