Reality is stranger than anything you've imagined. Particles exist in multiple states. Observation changes outcomes. Time may not flow at all. Explore it all — interactively.
Each module is a complete, interactive experiment. Not animations of someone else's experiment — yours to run, with real physics. Change the parameters. See what breaks. Understand why.
Fire electrons one at a time. Watch the interference pattern build. Toggle the detector and watch it vanish. The most beautiful experiment in physics — live.
→ Enter Lab 02 / 14A quantum system exists in all states simultaneously until measured. Not metaphor — real. Build intuition through hundreds of measurements.
→ Enter Lab 03 / 14Not about clumsy instruments. Drag the precision slider — watch the conjugate variable explode. Position and momentum cannot both exist as definite values.
→ Enter Lab 04 / 14Rotate the Bloch sphere with H, X, Y, Z gates. Watch probability amplitudes shift. Measure and collapse. Build your own quantum circuits.
→ Enter Lab 05 / 14Separate two particles to Tokyo. Measure one. The other responds instantly. Real, proven, and deeply strange. Bell's theorem made it testable.
→ Enter Lab 06 / 14A particle passes through a wall it has no energy to cross. Not magic — wave mechanics. Powers the sun, flash memory, and radioactive decay.
→ Enter Lab 07 / 14How does the quantum world become classical? Environmental entanglement destroys coherence. Slide from cryo qubit to macroscopic object and watch it vanish.
→ Enter Lab 08 / 14Every quantum measurement branches reality. All branches are real. Build the tree of your personal universe, one measurement at a time.
→ Enter Lab 09 / 14The past and future exist as fully as the present. Special relativity demands it. Drag your "now" through 4D spacetime and see another observer's tilted slice.
→ Enter Lab 10 / 14Electrons have intrinsic angular momentum with no classical analog. Spin-½ means a 720° rotation returns to the original state. Apply Stern-Gerlach fields.
→ Enter Lab 11 / 14Run Bell's experiment yourself. Hidden variables predict correlations ≤ 2. Quantum mechanics predicts 2√2 ≈ 2.83. Reality agrees with quantum. Run 1000 trials.
→ Enter Lab 12 / 14Electrons don't orbit — they inhabit probability clouds. Explore hydrogen orbitals 1s through 4f. See how energy quantization produces the periodic table.
→ Enter Lab 13 / 14Particles are excitations of quantum fields that permeate all space. The most accurate theory in science. Virtual particles, vacuum energy, and the Casimir effect.
→ Enter Lab 14 / 14Black holes evaporate. Virtual particle pairs near the event horizon, one escaping, create thermal radiation. Quantum mechanics meets general relativity.
→ Enter LabQuantum mechanics isn't just a physics theory. It's a fundamental revision of what reality is. It tells us that objects don't have definite properties until measured, that distant particles can be correlated in ways no classical explanation can account for, and that the act of observation is woven into the fabric of what exists.
These aren't interpretations or philosophy layered on top. They are the direct, experimentally verified predictions of the most accurate scientific theory ever constructed. The error rate of quantum electrodynamics is equivalent to measuring the distance from New York to Los Angeles and being off by the width of a human hair.
Understanding quantum mechanics doesn't require a physics degree. It requires the willingness to sit with deep strangeness and build intuition through direct engagement with the mathematics and the experiments.
Every concept has a live lab. Click, drag, measure. See the physics respond in real time.
Not dumbed down. The real mathematics, the real arguments, explained for human understanding.
Run your own Bell experiment. Watch hidden variable theories fail with 1000 trials of data.
From quantum computing to black hole radiation to the block universe. One coherent arc.
Start with curiosity. The mathematics is introduced through intuition, not thrown at you.
14 interactive labs. Real physics. No prerequisites. The quantum universe is waiting.
