Hi Rails Community,
I’m currently working on a theoretical physics model called the NKTg Law on Varying Inertia, which introduces a new way to describe motion in systems where mass changes over time (such as spacecraft burning fuel, dynamic particles, or complex simulations).
Although this might sound a bit “physicsy” for a Rails forum, I’d like to open a discussion on how such a model could be implemented or visualized in Rails or any Ruby-based backend if you’re into scientific computing or simulation tools.
What is the NKTg Law?
It extends Newtonian motion using two core formulas:
# Where p is momentum (mass × velocity)
nktg1 = position * momentum
nktg2 = mass_change_rate * momentum
These two quantities (NKTg₁ and NKTg₂) describe how an object tends toward or away from equilibrium, based on its position, velocity, and mass change over time.
Why Post This Here?
Because Ruby (and Rails) is more than web: we’re builders.
- Have you ever built or wanted to build a simulation backend in Rails?
- Are you working with physics data, sensor input, or data pipelines?
- Would such a model (or data structure) fit in any Rails-like project?
Even if you’re not doing physics, this is also about modeling complex relationships in code.

Would love your thoughts
- Has anyone used Rails for scientific or simulation work?
- Would this kind of model be interesting for plugin/gem architecture?
- Or maybe in conjunction with Ruby and WebAssembly?
Open to questions, collaborations, and even critiques.
Thanks for reading!
