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

The simple answer is that light and sound are waves. We can measure them and record them easily. They’re just made of vibrations or energy.
Scents are made of things. When you smell something, it’s actually tiny bits of it floating in the air that your nose picks up. Not so easy to record. It’s kind of like asking why can’t we record a house and just play it back. Much more complicated.
