A sequence can carry a message. Its representation and the rules used to read it both matter.
Background on this idea
Interactive explorationInvestigate a virtual garden. Change who receives an assignment card, uncover a hidden starting difference, run fair trials and discover why a pattern alone cannot settle what caused it.
Interactive explorationOpen a genuinely trained miniature Transformer. Change token tiles, inspect real attention and vector calculations, sample a continuation, and test the limits of a confident prediction.
Interactive explorationTrain a real classifier on editable inspection cards. Reveal a confident mistake, repair a misleading shortcut, and freeze your model before opening its reserved test.
Interactive explorationWrite a tiny real assembly program, watch values move through a processor’s logical parts, and stop at the instant an answer becomes stored state.
Interactive explorationInspect a connected CMOS cutaway, build a channel, find a circuit’s operating point and follow the charge and energy behind a changing bit.
Interactive explorationInspect the real EHT observation, then choose a direction in a calculated light map. Follow its exterior path, find its source and reveal two images of one tiny patch.
Interactive explorationWatch waves emerge from a buried source, pick synthetic arrivals and reveal the location one clue at a time. Test the clocks, depth and velocity assumptions—and compare the model with real recorded evidence.
Interactive explorationChange particle counts, pin the differences, and discover what names an element. Then prepare one-electron hydrogen states, collect possible position outcomes and match energy gaps to light.
Interactive explorationChange a fictional sleep history, catch the moment two curves meet, and separate a local clock change from a biological clock. Then follow light information from eye to brain.
Interactive explorationOpen a protein-vaccine example, build a response with traceable cell lineages, and compare later encounters. Then follow the separate route from vaccine mRNA to a protein.
Interactive explorationExplore how the immune system responds to an infection. Follow immune cells from skin to lymph node, inspect an antibody structure, and discover what immune memory leaves ready.
Interactive explorationNudge a membrane, discover when a spike appears, test its recovery, and cross a chemical synapse. Then inspect a real potassium-channel structure.
Interactive explorationTake apart a human ribosome, follow a message three letters at a time, then change a DNA base and discover what the peptide does.
