Physics
Superfluid and quantum vortices
A stirred condensate sheds quantised vortices and they crystallise into a lattice.

Makarov Physics Suite
200 interactive modules span mechanics, waves, optics, electromagnetism, quantum phenomena, fluids and thermodynamics. Work with physical objects, inspect detailed 3D apparatus and connect the motion to live measurements.

Physics
Semiconductors
The p-n junction from the inside: doping, band bending, the depletion zone and the diode's I-V curve from an honest drift-diffusion solver.
Physics
Bending waves in a bar
A struck free-free bar: bending waves are dispersive - the overtones are not integer multiples of the fundamental, unlike a string.
Physics
Heat engines
A gas piston runs Carnot, Otto and Stirling cycles on a live pV diagram: work per cycle, efficiency against Carnot's limit, and a refrigerator in reverse.
Physics
States of matter
Lennard-Jones molecular dynamics: cool a gas until it condenses and freezes, watch the structure sharpen, and meet the potential behind it all.
Physics
Method of mixtures
Hot metal into cold water: from the final temperature alone, the specific heat of the metal - if the calorimeter is counted too.
Physics
Betz limit
An actuator disc in the wind: brake the flow too little and you let it go, too much and the wake chokes the supply. The crest between them is 16/27 - and no blade can climb over it.
Physics
Schrödinger's cat
A 3D thought experiment about superposition, decoherence and measurement. Compare coherent and mixed states and collect outcome statistics.
Physics
Bell test (CHSH)
S = 2√2 against the classical bound of 2 - accumulated from sampled ±1 outcomes, not evaluated from a formula. Switch the source to local hidden variables and watch the same bench stall at 2.
Physics
Density anomaly of water
Ice floats because its lattice is open. Warm the water and the network breaks: density rises to a maximum at 4 °C, then falls again.
Physics
Molecular shapes
Molecules in three dimensions with their shapes worked out, not looked up: the library holds only what is bonded to what, and the tetrahedron, the ring, the octahedron and the buckyball fall out of a relaxation you can watch.
Some modules belong to more than one Suite. Shared experiments have one description here.
