{"id": "card_n_0a41c0e3298d", "kind": "note", "title": "Pheromones — the molecule is the message", "body": "A pheromone is chemistry acting as language: a molecule IS a signal. Sealed: a\n20-component blend encodes 2^20 = 1,048,576 distinguishable messages (~4.3 bits per component),\nand an ant's trail evaporates exponentially — at 90% per step, a ~6.6-step half-life (https://narrowhighway.com/s/cf33ee4a141a5eec4532535efbd2b7e5563cc8ac04c39c530d03c5b3806ebc45).\nThat decay is not a flaw, it is the ALGORITHM: because old trails fade, a colony with no map\nconverges on the shortest path (ant-colony optimization is a real algorithm lifted from the\nants). A male silk moth detects a few molecules of bombykol — near single-molecule sensitivity.\nPheromones DIFFUSE down a gradient (the continuity/diffusion equation) and DECAY (the exponential\nclock) — the fluid and the clock of this whole map, carried in a scent.\n\nThe deep point (Matt: 'pheromones act as signals'): a pheromone is one member of a single\nfamily — the SIGNAL, a physical carrier of information across a channel. Radio waves (EM), DNA\n(genetic), morphemes (linguistic), neurotransmitters (neural), and the sealed receipt of this\nvery engine (cryptographic) are all the same abstraction — Shannon's channel. The pheromone is\nthe chemical dialect of one universal grammar: information, carried. Honest boundary: the\ninformation math seals; which molecule means what is discovered biology (measured), and whether\ntrue HUMAN pheromones exist is genuinely contested — INCOMPLETE.
