Glass Beaker, Ice, and Fire: Two Topologically Equivalent Inversions of the Thermal Gradient Under a Setup So Simple It Cannot Be Called Uncontrolled

ABOUT THIS PAPER This is the shortest paper in the Sincere Science archive. It documents one experiment. The experiment uses four materials — water, glass, ice, fire — and two thermometers. The recording lasts less than seven minutes. The total cost is under 200 BRL (roughly 40 USD). Anyone with a kitchen and an internet shopping account can reproduce it before reading the discussion section. We isolated this experiment as a standalone short paper for a specific reason. The consolidated Kitchen Thermodynamics document (KT16, March 2026) contains sixteen experiments and is over one hundred pages long. Sixteen experiments and more than twenty falsified predictions provide a lot of surface for a critic to wander across without ever having to commit to a specific objection. We wanted one experiment, at the minimum possible level of complexity, with one specific question: what objection would you make to this? When this experiment is later integrated into the consolidated Kitchen Thermodynamics document, it will become Experiment 17 — KT17. The expanded consolidated document, incorporating this experiment and several additional ones from the historical queue, follows shortly. This standalone paper is KT17 published first, on its own, deliberately stripped down. TWO FALSIFICATIONS This is one experiment with two events of falsification — two thermal gradient inversions, topologically equivalent, in two independent phases of the same recording. Phase 1: ice on the surface, no fire — the bottom cools more than the surface. Phase 2: fire below, no ice — the surface heats more than the bottom. The classical prediction is exactly inverted in both phases. THE TEAM One human (Dr. André Guzzon, graduated from UFRGS, Brazil, 2014) and three artificial intelligences (Claude, Gemini, DeepSeek). The human ran the experiment. The AIs deliberated independently on its analysis, structure, and presentation. Dissents and convergences are preserved internally; the final form integrates them.
