## 2019 Project: symbolic Orrery
create personal tooling to comparisons of:
- number/detail of bodies
- newtonian / relativistic / MOND
- different solvers/numerical
- published ephemeris
should be able to tweak/"compile" all the math from symbolic high-level syntax.
also periodograms?
refs:
- SICM and func diff geo
plan:
- basic n-body solver with graphics in rust; not symbolic?
- play with structures to improve
- do basic solar system and compare existing
=> until matching basic ephemeris
- side: try other systems (attractors)
- revisit SICM and try other structures. symbolic input, digital orrery paper
- read and compare best current systems; import more complex models
- func diff geo book
tools/tech:
- rust, racket, julia, python, wasm, typescript
- gl, webgl
- inter-process plotting/graphics
- diff and other analysis
## Specific Graphical
These could all be xscreensaver things in rust?
- GPU fluid 2D: smoke, liquid
- n-body, attractors
- 3D Box2D constraint kinetics simulation thing
-> to understand rigid constraint satisfaction
- somewhat generic graphic runtime
-> takes in AST model or scheme
-> JIT compiles somehow?
-> solving with error propagation
-> fast interactive phase space exploration
-> periodograms
-> julia or rust?
## Big List
agent-based natural modeling
point/particle graphics
=> n-body simulations
=> cloth, water, gas
=> GPUs
optics and GEANT
computational physics
re-implement classic numerical routines
=> runge-kutta
BPF and other sub-turing-complete languages?
