01 / NOTES

  1. 01A System Cannot Vouch for ItselfGödel’s second theorem and Löb’s theorem put a hard limit on how far a reasoning system can certify its own soundness.9/21/2026 · Deep Tech→
  2. 02How Long an Idea LastsFor things that do not age, the best estimate of how much longer they will last is how long they have lasted already.8/17/2026 · Philosophy→
  3. 03A Network That Thinks by ThickeningThe slime mould Physarum polycephalum finds shortest paths without neurons, using one feedback rule between flow and tube width.5/11/2026 · Biology→
  4. 04The Most Irrational AngleSunflower seeds sit at the golden angle because it is the number that fractions approximate worst.2/27/2026 · Geometry→
  5. 05Measuring the RulerEvery measurement also tests the instrument, and how much it tests the instrument depends on what you already believed.12/6/2025 · Philosophy→
  6. 06The Three-Quarter PowerMetabolic rate scales with body mass to roughly the ¾ power, and the best explanation is about pipes, not cells.9/3/2025 · Biology→
  7. 07Below ThresholdThe threshold theorem turns quantum computing from a question of perfect parts into a question of good-enough parts arranged well.7/29/2025 · Deep Tech→
  8. 08The Paradox Is About ChoiceBanach–Tarski does not show that volume is broken; it shows what the axiom of choice lets you assert without describing.6/14/2025 · Mathematics→
  9. 09Theseus at the Cellular ScaleThe body does not replace itself every seven years, and the parts it never replaces are the interesting ones.3/22/2025 · Philosophy→
  10. 10Folding Is Not a SearchLevinthal’s paradox is less a puzzle about proteins than a lesson in choosing the wrong model of a problem.1/19/2025 · Biology→
  11. 11What Symmetry Lets You IgnoreNoether’s theorem is usually read as a source of conservation laws, but it is better read as permission to stop tracking things.11/30/2024 · Physics→
  12. 12The Price of ForgettingComputation can be free in principle; erasure cannot.10/21/2024 · Deep Tech→
