hello this a test version
Double Pendulum
Explore deterministic chaos with a real double pendulum. Adjust rod lengths, masses, initial angles, and watch the chaotic trajectory unfold with real-time energy tracking.
Particle in a Box
Visualize quantum wavefunctions for a particle confined to a 1D infinite square well. See eigenstates, probability densities, and energy eigenvalues for n=1 through n=8.
Quantum Harmonic Oscillator
Explore the quantum harmonic oscillator with Hermite polynomial wavefunctions. Compare classical vs quantum probability distributions at different energy levels.
Projectile Motion Lab
Fire projectiles with adjustable launch angle, initial velocity, and air resistance. Visualize trajectories and compare with analytical predictions.
Orbital Mechanics
Simulate planetary orbits using Newton's law of gravitation. Bodies interact via real N-body gravitational forces.
Electric Field Visualizer
Place point charges and visualize the resulting electric field lines and equipotential surfaces.
Electromagnetic Induction
Move a magnet through a coil and observe induced EMF. Vary the magnet strength, coil turns, and velocity.
Ideal Gas Simulation
Watch particles in a box obey the ideal gas law. Control temperature, volume, and particle count.
Carnot Heat Engine
Step through the Carnot cycle and track entropy, work, and efficiency.
Special Relativity Visualizer
Visualize length contraction, time dilation, and relativity of simultaneity. Adjust relative velocity from 0 to 0.99c.
Stellar Evolution
Simulate the life cycle of stars from protostar to white dwarf, neutron star, or black hole.
Gravitational Lensing
Place massive objects and see how they bend light from background sources.
