Rabbit holes.

The back rooms of the site, where physics, machine learning, and the question of identity turn into things you can touch. Each one is its own little world.

quantum measurementCollapseA site in superposition that resolves only when something conscious observes it./collapse
observer effectThe MirrorThe observer effect, turned around: it watches how you move, then shows you the reflection./mirror
machine learningThe Learning MachineA neural network learning live in your browser. Pick a shape; watch the boundary form./learn
general relativityEvent HorizonDrag a black hole and watch it bend the light behind it into a ring./horizon
scale invarianceRenormalizationScroll from the cosmic web to a quark and back. The same law at every scale./renormalization
artificial lifePrimordiaParticles, a few simple rules, an interaction matrix: somehow it decides to become alive./primordia
the cityMunichThe U-Bahn I actually live on: the full network, as a map you can plan a real journey on./munich
thermodynamicsHeat DeathPlay Maxwell's demon. Sort the hot from the cold. Order isn't free; you pay in work./heat-death
cosmologyFirst LightA cold start for the universe: the Big Bang to now, in fifteen seconds./first-light
chaosDeterminismTwo pendulums, identical to a thousandth of a radian, ending up in different lives./determinism
identityTwo EklavyasOne answer is me. One is a model trained on me. Tell us apart./two-eklavyas
pattern formationMorphogenesisReaction–diffusion you paint into; one rule, and the spots decide to happen./morphogenesis
emergenceSlime MoldA brainless organism grows a trail network between Munich landmarks — and rediscovers the map./slime-mold
harmonicsFourierDraw any closed shape; a chain of rotating circles redraws it. Any path is a sum of circles./fourier
resonanceCymaticsDrag a frequency; a Chladni plate finds the standing wave in sand, and you hear the tone./cymatics
special relativityWorldlineYour life on a spacetime diagram. Drag to boost the frame; the light cone never moves./worldline
geometryTesseractA four-dimensional cube, rotating in 4D and projected to your screen. A shadow of a higher dimension./tesseract
quantumDouble-SlitFire quanta one at a time; they interfere with themselves. Look at which slit, and the fringes die./double-slit
n-body gravityGravityA universe you build by hand. Drop a star, fling one into orbit, watch a galaxy fall out of a cold cloud./gravity
non-Euclidean geometryHyperbolicA plane with too much room. Regular tilings flat space forbids, in the Poincaré disk — drag to walk where the edge is infinitely far./hyperbolic
