Don't argue about how something works. Simulate it.
I build interactive learning modules and simulations that turn contested or hard-to-explain questions into demonstrable, data-grounded answers — for teams, educators, and organizations who need people to actually understand something, not just be told it.
It started with one stubborn question
It all started with a simple question I couldn't let go of: does gravity actually explain how planets and moons move — or is that just the story we've settled for? Instead of arguing about it, I built a simulator.
I fed it real astronomical data from NASA and JPL, ran a gravity-only physics model side by side with a density-based model, and watched which one actually predicted what telescopes have measured for centuries. Gravity won — precisely, consistently, every time.
That process became the whole philosophy behind Crafted Simulations: when people disagree about how something works, don't debate it. Build something interactive, ground it in real data, and let the answer become undeniable on its own.
Interactive tools built around your specific question
Every engagement starts with what you're trying to prove, teach, or settle — the simulation is built to fit that, not the other way around.
Physics & systems simulations
Custom-built interactive models — orbital mechanics, force laws, fluid or thermal systems — that let people manipulate variables and see real cause and effect.
Learning & training modules
Interactive modules for classrooms or internal training programs, designed to build real intuition instead of rote memorization.
Data-driven "mythbusting" tools
When an organization needs to settle a recurring debate or misconception, I build a side-by-side comparison against real, sourced data — not just an explainer.
Orbital Mechanics Simulator
Gravity vs. density, tested against real planetary data
An interactive orbital mechanics simulator where you adjust mass, density, and velocity to watch a body trace circular, elliptical, and hyperbolic paths in real time. A built-in toggle switches between a gravity-only physics model and a density-based model — then shows, side by side, which one actually matches observed planetary and moon data pulled from NASA and JPL.
From your question to a working simulation
Define the question
We nail down exactly what needs to be demonstrated, taught, or settled — and who the audience is.
Source the data
I pull in real, credible reference data so the simulation reflects reality, not just an assumption.
Build the interactive model
A working, adjustable simulation gets built and refined until the result is clear at a glance.
Deliver & hand off
You get a hosted, ready-to-share link (or the source, depending on the engagement) — no explanation of internal process required.
Every project is scoped individually
Cost depends on the complexity of the question, the data involved, and how the final tool will be used. There's no fixed package — tell me what you're trying to demonstrate, and I'll send back a custom quote.
