![]() Joel Mainland is one of the authors of that report. For example, is it grassy? Or more meaty? Perhaps floral? Dr. This week in the journal Science, researchers describe developing an AI model that, given the structure of a chemical compound, can roughly predict where it's likely to fall on a map of odors. Molecules with a similar chemical structure may smell quite different-while two molecules with very different chemical structures can smell the same. While we know that many sulfur-containing molecules tend to fall somewhere in the 'rotten egg' or 'skunky' category, predicting other aromas based solely on a chemical structure is hard. If you want to predict what something sounds like, frequencies can be a guide-a frequency of around 261 Hertz should sound like the musical note middle C. Light with a wavelength of around 460 nanometers is going to look blue. ![]() If you want to predict the color of something, you can talk about wavelengths of light. ![]()
