• Patch Notes·24 Sept 2026Official

  This is the first patch since the 16 September build.

  This is the first patch since the 16 September build. The biggest single change is in Circuits: the schematic you draw is now also built as parts on a breadboard. Resistors get their colour bands from the value you typed, the lamp glows by the power the simulator actually dissipates, and the jumpers show which way the current runs. The module opens on the bench; the editor is one checkbox away. Nine presets, from a lamp with a switch to a Wheatstone bridge and an LC filter.Five modules got a task card: keep a Kepler orbit going for two years, float a block exactly half submerged, hold Coriolis for a full day, hit 1.5× Doppler, stop the striking ball in Collisions. Five got instruments you can drag around the scene - a ruler and a stopwatch on the brachistochrone and the rolling race, a thermometer in Calorimetry, a protractor in the prism, a manometer in the ideal gas.Scenes that were flat drawings are now objects: the Ising model is a landscape of magnetisation you can walk around (or switch back to the map), Radioactivity is a tray of nuclei that flash when they decay, with a Geiger counter reading the model's own decay times, Blackbody is a glowing sphere in front of its spectrum, Linkages are steel bars on a board. Kepler, Rømer and Retrograde share one sun now, with limb darkening and a corona.Smaller things you will notice: the description card is short and opens on "More"; charts have a legend and a cursor that reads the actual data point; the scene fits itself into the frame around the card and the panel, and I went through a 251-frame tour and moved about fifty cameras by hand. Twenty-five modules that are two-dimensional by nature no longer rotate in 3D when you drag them - that was a bug, not a feature. Nine modules start running the moment they open instead of waiting for Start.Fixes: the tokamak vessel was lying 90° off its plasma; cloud-chamber tracks took their length from the full range instead of the chamber; the electron-optics plates were silently...

  A visual pass over the whole suite, guided by a full screenshot review of every module.Scenes rebuilt as real apparatus:Twelve modules that used to show boxes and lines on a starfield now show the experiment: the photoelectric bulb on its stem with a moving-coil microammeter, the relativity train with three carriages and a station, the Bell test bench with polariser wheels and a meter that goes into the red past the classical limit, the laser cavity with its flash lamp and a beam stop that lights up at threshold, the Stern–Gerlach magnet with a knife edge and a trough, the Davisson–Germer goniometer with the Bragg planes lighting up on the crystal at the peak, the tokamak as a machine with sixteen copper coils and a glowing plasma that fades when confinement is lost, the infrared gas cell with a spectrometer board, the static-electricity room, the quantum block track with a camera on a tripod, the p-n diode wired into a circuit with an LED and an ammeter, and the hydrogen atom.Hydrogen orbitals now go all the way to the f states (n, l, m as sliders up to 4f), with an optional translucent isosurface and a section plane, and a transition that emits a photon in the colour of its spectral line.Electric field - charges are now polished metal spheres under scene lighting, and the field lattice is made of small 3D arrows.Gravitational waves - the space-time sheet is a lit surface, and the merger flashes.Across the suite:The description card no longer runs off the screen: it caps at half the window and scrolls.Thirty-six descriptions that had grown into walls of text were cut to a paragraph plus a few formulas.Bloom no longer washes bright scenes out to white (fractal tree, galaxy, L-systems).Chart axes no longer print things like 3.03e+0.Stars in the space backgrounds are round again.Several scenes that read as "glass" because their solids were drawn inside the glow pass are solid again (Pascal, Casimir, quantum eraser, EM wave, static electricity).Coriolis globe is lit fo...

  Ruthenford Scattering

  In 1909, Geiger and Marsden fired alpha particles at a gold foil a few thousand atoms thick. Thomson's model said the positive charge was spread across the whole atom, so everything should pass through with a slight nudge.Most did. About one in eight thousand bounced straight back.Rutherford compared it to a 15-inch shell rebounding off tissue paper. His 1911 answer: nearly all the mass and all the positive charge sit in a nucleus tens of thousands of times smaller than the atom. Scale the atom to a stadium and the nucleus is a fly on the centre spot.It wasn't a hunch. He derived the scattering law - the fraction deflected by angle θ falls as 1/sin⁴(θ/2) - and Geiger and Marsden checked it against angle, foil thickness, particle energy, and four different metals. It held.Half a century later, SLAC used the same trick at higher energy and found quarks inside the proton. The LHC still runs on that logic.Want to know what's inside something? Throw something at it and watch how it comes back.

  Update: the nucleus-and-atom ring, and equations everywhere

  Update: the nucleus-and-atom ring, and equations everywhereThe eight newest modules (Cyclotron, Mass spectrometer, Reactor control, Compton scattering, Muon lifetime, Cherenkov radiation, Alpha decay, Cloud chamber) got a second pass. They now run in time instead of showing a static diagram: the cyclotron beam spirals out, slips phase or leaves through a deflector; the spectrometer plate fills up one ion at a time; the reactor bank follows the wheel at a drive's pace and a scram lets it fall; Compton photons scatter into a cone and a detector on a goniometer arm counts what lands in it; muons rain from 15 km and die where the decay length says; the Cherenkov ring builds on a detector plane photon by photon; the alpha knocks on the wall of its well between escapes; the cloud chamber sits in a glass box with vapour inside. Most of it can be dragged: the detector arm, the reactor's control bank, the energy plane in Alpha decay.Two of these came out of the physics itself rather than the plan. Trim the cyclotron's RF frequency 0.8 % below f₀ and the energy ceiling more than doubles; 0.9 % and it falls off a cliff. And 40Ar²⁺ lands exactly where 20Ne⁺ does - a spectrometer reads m/z, not m.By request from the reviews: every module now shows its equations, all 140 of them.Fixed: transparent-looking benches and instruments in bloomed scenes, flicker on coplanar surfaces, a few wrong units on labels.
