It seems like any color or sound can be accurately encoded (and recreated) with just a few numbers. Yet that doesn’t seem to be the case with smell or flavor. You can take a photo or sound recording and it’ll be a faithful recreation, but there’s no way to do that with smells or flavors. Is it a technology limitation or is there something fundamental to them that makes it harder to encode?
In: Physics
They can. Any smell is the result of some chemical or combination of chemicals. If you know the specific chemical(s) and the concentration (e.g. parts-per-million). Then you can reproduce the smell.
I suspect there would be more to it, like air temperature and humidity, but I’m not sure.
