150 laws, principles, and structures that recur across unrelated domains — paired with an interactive atlas and a working TI-84 calculator for the formulas behind them.
Browse every law as a card, traverse them as a force-directed graph, sweep them across a timeline, or take a random walk through their citations.
A faithful TI-84 with physics, math, electrical, atmospheric, thermo, optics, orbital, chemistry, and signals — every formula plots itself on the LCD.
Untranslatable words, Greek and Latin roots, prefixes, suffixes, and uncommon English emotion-words — with etymology, usage, and native-voice audio.
A drafting board for advanced geometry — point-to-point lines, regular and star polygons, spirographs, alignment and boolean fuse, with a library of mathematical, sacred, and common figures.
A visual reference of technical components from high-end apparel, architecture, botany, culinary, music, museums, luxury homemaking, hotels, and bartending — teaching the refined use of expressive terms.
Chemical formulas and stoichiometry for domestic, industrial, cosmetic, agricultural, pharmaceutical, military, and food chemistry — with sourcing, handling rules, and trade names.
