Chemistry authors simply cannot resist slapping that hand-glove analogy onto any paper about chirality. It's the scientific equivalent of using Flex Tape to fix everything! For the uninitiated, chirality refers to molecules that exist as non-superimposable mirror images (like your left and right hands). Instead of explaining this complex 3D molecular property with, I don't know, actual chemistry , authors default to "imagine your hands are molecules!" in every. single. introduction. The perfect example of when creativity goes to die in academic writing. Next paper should just have a QR code linking to this meme instead of paragraph three.
