Convection
A simple box of fluid which responds to heating and cooling, demonstrating thermal energy transfer
Interactive Science Playground
simulations.science, is an interactive playground for exploring scientific concepts. The simulations are designed to be accessible and easy-to-use, promoting an intuitive understanding of complex phenomena. These interactive tools help students, teachers, and science enthusiasts visualize phenomena like heat conduction, convection, radiation, buoyancy, gas pressure, thermodynamics, radioactive decay, special relativity and orbital motion.
Conduction
A lattice of atoms which vibrate and transfer thermal energy through direct molecular interaction
Radiation
A glowing heater warms matte black and polished silver blocks across a vacuum by infrared radiation
Maxwell's Demon
A box of particles with a gate controlled by a demon, entropy, information cost and the second law of thermodynamics
Buoyancy
Draw an object from different materials and drop it into a liquid to see why things float or sink
Pressure
Gas particles striking the walls of a balloon, box, syringe or piston, showing how temperature, volume and particle count set the pressure
Nuclear Decay
Build nuclei from protons and neutrons, then watch them decay by alpha, beta, gamma or fission with real half-lives
Special Relativity
Light moves at the same speed for everyone: see how that slows moving clocks, shrinks ships and breaks simultaneity
Orbits & Gravity
Drag stars, planets and black holes into orbit and watch Newton's gravity produce Kepler's laws, then Einstein's turn the ellipses into rosettes
