Five technical topics, each unfolded three ways at once — intuition for a curious newcomer, math and mechanism for an undergraduate, and edge cases for a researcher — with live in-browser demos, build-from-scratch code threads, and field-guide anatomy plates.
Predict in embedding space, not pixel space — LeCun's bet, from I-JEPA to LeJEPA.
An orbit is falling sideways fast enough to keep missing the ground.
Steer probability amplitudes so wrong answers cancel and right answers add.
How materials stretch, bend, and snap.
Fields, charges, and Maxwell's unification.
