🧵 Olfactory science

Anonymous No. 16242450

>“Did you ever try to measure a smell?” Alexander Graham Bell once asked an audience of graduands at a high school in Washington DC.

>He then quizzed the probably confused class of 1914 as to whether they could tell when one scent was twice the strength of another, or measure the difference between two distinct odours. Eventually, though, he came to the point: “Until you can measure their likenesses and difference, you can have no science of odour,” Bell said. “If you are ambitious to find a new science, measure a smell.”

So how come there is little attention and work has occurred in olfaction versus other fields since smell is an important sense of the body.

I know there's a company that has an electronic nose that uses real smell receptors from humans to measure smell. Forget which one it was though.

Why is it hard to measure smell?

Because chemFETs are garbage and we don't really have a good way to interface tissues with electronics. We're getting better though. I would not be surprised to see useful "electronic noses" in 10-15 years.

No idea. Smell is particles in the air. You can measure how many ppm it takes for a smell to be noticeable by the average person. Just let more people try it to get a reasonable average.

I can not only measure the smell, I can imagine the smell.

You would think it's number of stinky particles hitting whatever membrane, but it's probably considered a consciousness problem. Is your red my red? Do your wife's armpits smell bad to you while smelling delicious to me? To what degree? I don't think you could reliably measure how a smell is interpreted.
