SUN-EARTH-MOON SYSTEM VISUALIZER
A rolling-coin model of the Sun, Earth, and Moon that shows tidal locking and lunar phases. Periods and phase geometry are faithful; distances are not to scale.
SOLAR SYSTEM
It draws the solar system from NASA orbital data for today or any day from 2001 to 2031. You can scrub through 29 years of planetary motion.
SATURN V ASCII LAUNCH
The Apollo 11 liftoff plays as truecolor ASCII video in the terminal. Install instructions are in the repo.
PERSISTENT MEMORY FOR LLM AGENTS
aelfrice stores LLM agent memory as Bayesian-scored beliefs and uses no embeddings. It detects corrections without LLM calls (92% accuracy) and bridges vocabulary gaps at 99.5% recovery. The current version is 4.0, and I publish every benchmark re-run, including the ones that scored lower.
DIFFERENTIABLE ROCKET SCIENCE
This neural net learns spacecraft maneuvers by backpropagating through the physics. I rebuilt it in 2026 from a 2021 course project that failed. On 3-D circularization one checkpoint reaches 92.3% success, and the best-fuel checkpoint uses 1.03x optimal fuel. It rediscovered an operational maneuver and flew a ballistic lunar capture with no capture burn. The original failure is kept in the repo.
MINING SATURN'S RINGS
A concept study for flying Saturn B-ring ice home with the cargo as the propellant tank. I ran 215 pre-registered rounds trying to falsify the concept. The commercial mission did not close; the one surviving corridor is only an existence proof. The full record is in the repo.
