Concepts Lab
Interactive simulations to explore fundamental concepts. Click on any experiment to start.
Pendulums
Explore chaotic motion with multi-segment pendulums. Add more segments and amplify the chaos.
Projectile Motion
Launch projectiles and observe parabolic trajectories under gravity. Adjust angle, velocity, and air resistance.
Orbital Mechanics
Simulate gravitational orbits. Place masses and watch them interact through Newton's law of gravitation.
Fractals
Explore self-similar structures: the Mandelbrot set, Julia set, Burning Ship, Sierpinski triangle, and Barnsley fern. Zoom in to discover infinite detail.
Atomic Structure
Explore electron clouds, orbital probability densities, and the periodic table. Visualize s, p, d, and f orbitals in 3D.
Wave Interference
Visualize constructive and destructive interference patterns from multiple wave sources.
Spring-Mass System
Study simple harmonic motion with adjustable spring constants, damping, and driving forces.
EM Field Lines
Place charges and observe electric field lines and equipotential surfaces in real time.
Quantum Fields
Discover the fundamental fields that govern reality — electromagnetic, strong, weak, and Higgs — and how particles emerge from their interactions.
Relativity
Visualize spacetime curvature, time dilation, and length contraction. See how mass warps the fabric of space.
