Physics Labs
Analyze experimental data, run simulations from first principles, and discover new physics.
Atomic Spectra
NIST ASD · Emission Lines
Query the NIST Atomic Spectra Database and render live emission line spectra for any atom or ion — colored physically by wavelength. Explore the sodium D lines, rubidium laser-cooling transition, and the hydrogen Balmer series.
Photoelectric Effect
Einstein 1905 · Extract h
Vary photon frequency and metal work function in real time. Measure stopping voltage, build V_stop vs. ν curves, and extract Planck's constant h from the slope — recreating the experiment that won Einstein the Nobel Prize.
Collider Events
CERN Open Data · CMS Dimuon
Analyze real CMS collision events from CERN Open Data. Reconstruct invariant masses from muon pairs and rediscover the Z boson at 91 GeV — exactly the procedure used in the original discovery.
Condensed Matter
Band Structure · Fermi Energy
Visualize Bravais lattices in 3D, compute density of states, and explore how Fermi energy and band gaps vary across metals and semiconductors. Tune doping levels and temperature.
Exoplanet Transits
Kepler · TESS · Transit Fitting
Load real Kepler and TESS photometry light curves. Fit transit models to extract planetary radius, orbital period, and semi-major axis — the same pipeline professional astronomers run.
Quantum Tunneling
Schrödinger Equation · Live
Solve the time-dependent Schrödinger equation in your browser. Watch Gaussian wave packets collide with arbitrary barrier potentials, observe resonant tunneling, and measure transmission coefficients.
Quantum Entanglement
Bell Tests · CHSH Inequality
Simulate photon-pair Bell test experiments. Sweep detector angles, accumulate coincidence counts, and watch the CHSH parameter S exceed 2 — violating Bell's inequality in real time.
Particle Detector
Track Reconstruction · Calorimetry
Simulate a generic particle physics detector. Visualize charged particle tracks bending in a solenoidal magnetic field, calorimeter energy deposits, and PID from ionization (dE/dx).

Each lab is built to let you do the same physics as working researchers — real data, real analysis, right in your browser.
