Mental Models (https://jamesclear.com/mental-models) In late August of 2005, one of the most dangerous tropical storms in history began brewing. The waters of the Gulf of Mexico were unusually warm that month, and the high temperatures transformed the ocean basin into a giant cauldron with the optimal conditions for growth. As the tropical storm cut across the tip of Florida and entered the Gulf, it immediately began to swell. In less than 24 hours, the storm doubled in size. And

syn-Propanethial S-oxide (C3H6OS) is a gas that acts as a lachrymatory agent (triggers tearing and stinging on contact with the eyes). The chemical is released from onions, Allium cepa, as they are sliced. The release is due to the breaking open of the onion cells and their releasing enzymes called alliinases, which then break down amino acid sulfoxides, generating sulfenic acids. A specific sulfenic acid, 1-propenesulfenic acid, formed when onions are cut, is rapidly rearranged by a second enzyme, called the lachrymatory factor synthase or LFS, giving syn-propanethial S-oxide. The gas diffuses through the air and, on contact with the eye, it stimulates sensory neurons creating a stinging, painful sensation.
