There is No "Smell Pixel"

There is no way to interpolate between two smell molecules. True, odors can be mixed together to form millions of scents. But the world’s smells can’t be broken down into just a few numbers on a gradient; there is no “smell pixel.” Think of it this way: colors and sounds can be measured with rulers, but odors must be looked up in a dictionary.
