Simulations
Interactive, watermarked physics demonstrations — pick one to adjust its parameters and run it.
Blackbody Glow (Colour Temperature)
ORBITHeat an object toward a chosen target temperature and watch it glow the colour a real blackbody emits — deep red to blue-white — while its radiated power rises steeply with temperature.
Locked — requires Orbit →
Calorimetry / Thermal Mixing
FREEBring two masses at different temperatures and specific heats into contact — watch both temperatures converge exponentially to the exact energy-conserving equilibrium temperature.

Ideal Gas (PV = nRT) Piston
INTERSTELLARLive interactive gas cylinder — set the amount of gas, then drag temperature and applied pressure and watch the piston respond in real time as PV=nRT holds exactly.
Locked — requires Interstellar →
Kinetic Theory of Gases
FREEFill a box with gas particles at a chosen temperature and count — watch them bounce elastically off the walls with speeds drawn from the Maxwell-Boltzmann distribution, and see average kinetic energy track temperature exactly.
Open simulation →
Newton's Law of Cooling
FREEPlace an object at a chosen starting temperature into an ambient environment — watch it cool (or warm) exponentially toward the ambient temperature, and see the time constant control how fast it gets there.
