Nonlinear terms and full time evolution require numerical solution. Many real morphogenetic systems involve gene regulation, cell movement, and mechanical forces beyond simple diffusion. Experimental confirmation in living embryos came decades later and remains partial for specific cases. The ring geometry is a mathematical convenience, not a universal biological form.","status":"active","vx_hash":"e71295fed64784933c95741f74132ceb6376ddb3ec006459c6c4109b403f2610","semantic_hash":null,"version_hash":null,"version":1,"sources":[],"falsifiers":[],"tier":null,"backed":null,"transcludes":null,"chain_head":"d9ce862301aedb15e4a597baaa3815f5f29ce83a487aa6ac8fca8b6bb93d70b6","chain_length":1,"chain":[{"n":1,"op":"genesis","ts":"2026-07-17T02:37:39.354Z","actor":"owner","text_sha":"612ea15fd6dca507eed89825111c8686ef6d7d2f93b31aafeba389ffe5f1535a","detail":{"divided_from":"body","block":18,"kind":"p"},"prev":"genesis","hash":"d9ce862301aedb15e4a597baaa3815f5f29ce83a487aa6ac8fca8b6bb93d70b6"}],"claim_ids":[],"last_op":{"op":"genesis","actor":"owner","ts":"2026-07-17T02:37:39.354Z"},"consolidated_into":null,"stable_url":"https://miscsubjects.com/i/div/paper-turing-a-m-1952-the-chemical-basis-of-morphogenesis/d18"},{"id":"d19","kind":"p","type":null,"order":19,"text":"Weinberg-style reductionist objection applies directly: the account explains pattern via known physics and chemistry; no new fundamental law is claimed or needed.","status":"active","vx_hash":"a972f210695010b76538be4d146d695d558753577f0f4708678bfa5913f37fa3","semantic_hash":null,"version_hash":null,"version":1,"sources":[],"falsifiers":[],"tier":null,"backed":null,"transcludes":null,"chain_head":"e792360b20aa989313f57b58de1bbb3aa0cdb76378cabb6fd48aa05f1ed879bd","chain_length":1,"chain":[{"n":1,"op":"genesis","ts":"2026-07-17T02:37:39.354Z","actor":"owner","text_sha":"4182471fb6b43d561521332f8acffca4965361dad86880e8c2a3b8275529e0d0","detail":{"divided_from":"body","block":19,"kind":"p"},"prev":"genesis","hash":"e792360b20aa989313f57b58de1bbb3aa0cdb76378cabb6fd48aa05f1ed879bd"}],"claim_ids":[],"last_op":{"op":"genesis","actor":"owner","ts":"2026-07-17T02:37:39.354Z"},"consolidated_into":null,"stable_url":"https://miscsubjects.com/i/div/paper-turing-a-m-1952-the-chemical-basis-of-morphogenesis/d19"},{"id":"d20","kind":"h","type":null,"order":20,"text":"## Further Reading on Site","status":"active","vx_hash":"6ab92d2ac8549198e2ac20942ef9d9d70a84af3eaf865566aeed0ee92f1132e2","semantic_hash":null,"version_hash":null,"version":1,"sources":[],"falsifiers":[],"tier":null,"backed":null,"transcludes":null,"chain_head":"bf3fe1be77ff0241ad76f208b020ae7c7a337d594475b352fa55cc92c3a97ebb","chain_length":1,"chain":[{"n":1,"op":"genesis","ts":"2026-07-17T02:37:39.354Z","actor":"owner","text_sha":"94c404f9693fbc637eada09e35559a1baddb949e7815a6a656b8af83a2dd0a8e","detail":{"divided_from":"body","block":20,"kind":"h"},"prev":"genesis","hash":"bf3fe1be77ff0241ad76f208b020ae7c7a337d594475b352fa55cc92c3a97ebb"}],"claim_ids":[],"last_op":{"op":"genesis","actor":"owner","ts":"2026-07-17T02:37:39.354Z"},"consolidated_into":null,"stable_url":"https://miscsubjects.com/i/div/paper-turing-a-m-1952-the-chemical-basis-of-morphogenesis/d20"},{"id":"d21","kind":"p","type":null,"order":21,"text":"See /a/oip-the-ladder for the full progression from difference to mind.
