"Emmy: Moldable Physics and Lispy Microworlds"
summary
Claims an open source, Mathematica‑like environment built in Clojure that actually runs textbooks as interactive code. Emmy composes Sussman’s 65,000 line utils with ClojureScript, Clerk and a Mathbox‑style renderer to emit JavaScript and GPU‑ready code, auto‑generate interactive sliders and viewers, and simplify symbolic forms up to producing Einstein’s field equations test. A PQ torus knot demo runs twice as fast as handwritten JS, a dual‑number derivative operator yields live Taylor series, and the notebook documents execute and animate correctly.
