Measurement & Mathematics
Units, estimation, vectors, graphs, algebra, geometry, calculus, differential equations, linear algebra and probability.
LIVE INTERACTIVE PHYSICS
Don't just read physics.
Move it.
Travel from the cosmic web to quantum scales, change the rules, launch experiments and discover why the Universe behaves the way it does.
FREE PLAY IS DEFAULT Missions are always optional. Nothing blocks exploration.

START ANYWHERE
Choose a phenomenon
Each space is a simulation first. The explanation and mathematics unfold around what you do.
EXPERIMENT WITHOUT CONSEQUENCES
Break the Universe
Change a rule and compare what follows. This mode labels conceptual approximations clearly rather than pretending every altered-universe outcome is a full first-principles simulation.

PLAYGROUND PREVIEW
INTERACTIVE LABORATORY
Make the equations move.
Every control changes the model immediately. Pause it, push it too far, reset it, or ignore the lesson entirely.
STABLE ORBIT
OPTIONAL CHALLENGES
Prove it to yourself.
No grades. No streak pressure. Missions simply notice what you do in the sandbox and reward successful experiments.

FROM FIRST PRINCIPLES TO THE FRONTIER
The complete physics path
The live labs are only one entrance. The architecture is already split into reusable engines so these branches can progressively become interactive worlds rather than separate textbook chapters.
Mechanics & Gravity
Kinematics, forces, conservation laws, oscillation, rotation, orbital mechanics, Lagrangians and Hamiltonians.
Waves & Fourier Ideas
Oscillation, superposition, interference, resonance, normal modes, sound and Fourier decomposition.
Optics
Geometric optics, diffraction, polarization, interference, imaging, lasers and coherence.
Electromagnetism
Charge, fields, potential, circuits, magnetism, induction, Maxwell equations and electromagnetic waves.
Thermodynamics
Temperature, heat, work, entropy, engines, ensembles, kinetic theory, phase changes and emergence.
Special Relativity
Spacetime, Lorentz transformations, simultaneity, energy–momentum and relativistic dynamics.
General Relativity
Metrics, geodesics, curvature, Einstein equations, black holes, gravitational waves and relativistic cosmology.
Quantum Mechanics
States, amplitudes, operators, uncertainty, wells, barriers, angular momentum, spin and entanglement.
Nuclear & Particle Physics
Nuclei, decay, scattering, symmetries, the Standard Model, quarks, leptons, gauge fields and the Higgs mechanism.
Condensed Matter
Solids, bands, semiconductors, magnetism, superconductivity, quasiparticles and collective behaviour.
Astrophysics & Cosmology
Stars, compact objects, galaxies, cosmic expansion, the early Universe, dark matter, dark energy and open questions.
