01 / GRAVITATIONAL MISCHIEF
Break the orbit.
Three bodies. One delicate dance.
It only takes one intruder to change everything.
That intruder is yours.
Drag empty space. Release a new world into the dance.
Controls & keyboard +
Space: pause. R: reset. Enter: launch. Tap the field or use these controls without dragging. Swipe outside the field to scroll. Reduced motion starts paused.
Softened Newtonian N-body model · dimensionless units · max 12 bodies · no collision merging. A separate browser experiment inspired by my Earth–Sun project.
02 / INVISIBLE RULES. VISIBLE CONSEQUENCES.
Bend a
beam.
Move an invisible magnetic field through a stream of particles. Positive and negative charges peel apart. Neutral particles keep going.
POSITIVE NEGATIVE NEUTRAL
I turn physical descriptions into software that can be explored.
What am I seeing?
A 2D charged-particle beam in a localised Gaussian magnetic field. A magnetic force bends a moving charge without changing its speed; neutral particles pass straight through. Moving the field changes future paths. Dimensionless educational model; no electric field or particle collisions.
The Boris particle integratorDrag the field. Opposite charges take different paths.

03 / THE UNEXPECTED FLIP
Trust the
unexpected.
Spin a body around its middle principal axis. It flips, even without an external torque. Change to its long or short axis and the rotation settles into a different kind of motion.
Flick to disturb the spin. Change the axis above the scene. This is the kind of hidden behaviour that keeps me building numerical experiments.
Why does it flip?
The intermediate-axis theorem: rotation near the middle moment of inertia is unstable. This uniform cuboid follows Euler’s rigid-body equations and a quaternion orientation, integrated with RK4. A flick adds an impulse; between flicks the body is torque-free. The lime vector shows world angular momentum. Numerical error is finite.

THE HUMAN IN THE LOOP
Build it.
Question it.
I’m Prathmesh. A software engineer with a habit of looking underneath the interface. Computers, physical systems, strange little experiments — I like finding out how they work.
