Work in Progress
These projects are under active development and not yet ready for public use.
Book Explorer
Browse a curated slice of freely readable Open Library books by their own real subject tags — then read them on the spot or send them to your library, Libby, or Amazon.
Aerial Time Machine
Pan and zoom a live satellite map of Earth, scrub through years of real Sentinel-2 and Landsat imagery, or swipe-compare two dates side by side. Ask an AI guide to fly you anywhere.
Historical Battles Explorer
Explore major wars battle by battle on an interactive map — where each fight took place, the generals and regimes involved, the victor, and the strategy and tactics used.
Pendulum & Spring-Mass SHM Lab
RK4-integrated nonlinear pendulum and damped spring-mass oscillator with live phase-space and energy plots. Watch the small-angle approximation break down in real time.
Standing Waves & Resonance
Drive a string at one end and hunt for the harmonic series. Live node/antinode envelope and a harmonic-scan indicator show resonance as it happens.
Collisions Lab
1D rail and 2D sandbox collisions built on Matter.js. Adjust mass and restitution to see momentum conservation and kinetic energy loss live.
Projectile Motion & Drag
2D projectile motion with quadratic air drag, compared live against the ideal vacuum trajectory. See exactly how much range and height drag costs you.
Exploratorium
Walk through an open 2D world and discover interactive physics and math exhibits.
Learning Resource Hub
An AI-organized index of the web's education resources — tens of thousands of free and paid courses, tutorials, books, docs, and videos from MIT, Coursera, Khan Academy, edX, Microsoft Learn, OpenStax, Yale, and more. Browse by subject, build an AI learning path, save favorites, or chat with the discovery assistant.
Hubble Space Telescope Gallery
Browse thousands of Hubble Space Telescope images organized by astronomical object — galaxies, nebulae, stars, star clusters, solar system, black holes, and exoplanets.
RPG Adventure
A text-based D&D-style adventure game. Create a character and let an AI Dungeon Master guide you through dungeons, forests, and castles. Free trial, then sign in to keep playing.
Classical Music Explorer
Browse 300+ classical composers and thousands of works by era and genre. Explore Baroque, Romantic, and Modern pieces with direct links to YouTube and Spotify.
