The hidden springs of a belief
Find Gaussian springs inside a Beta belief, then listen with complex rotating arrows.
Explore the survey 17 minWhen evidence takes different roads
Reconstruct beliefs from report fragments, hidden causes, active questions, and complex joint tables.
Explore the survey 26 minWhen the numbers refuse to fit
Test joint possibilities, pay for signed weights, and follow evidence through time.
Explore the survey 21 minEvolution has an order
Explore selection, mutation, lineage histories, and the Beta distributions of wandering populations.
Explore the survey 18 minHow much can one trial teach?
Separate surprise from learning, watch mass cancel Fisher curvature, and find pi in the price of coding an unknown coin.
Explore the survey 18 minA cell chooses what to remember
Gene switches preserve chosen fates; adapting receptors remember the background to keep noticing change.
Explore the survey 17 minWhen a channel carries mass
Read channel overlap as cone mass, turn a Lorentz factor into an error exponent, and discover when forgetting labels costs information.
Explore the survey 22 minHow life prepares for an uncertain world
Let a receptor learn by waiting, then grow a population across two possible futures.
Explore the survey 15 minA decoder that computes in rapidity
Build a decoder from two cone operations: multiply velocities to check parity, add rapidities to combine messages, and watch information polarize.
Explore the survey 17 minHow to read a living landscape
Turn cell axes, follow molecular journeys, and discover new categories without losing old answers.
Explore the survey 16 minHow far apart are two quantum messages?
Turn a quantum receiver, derive a mass-to-error law, and discover how one average state can hide many different messages.
Explore the survey 17 minMarkets that learn
Pay to move a market quote, spend a business opportunity on learning, and turn an experiment toward what a firm still cannot distinguish.
Explore the survey 24 minA brain in the evidence cone
Follow an animal through sensing, learning, memory, clocks, and movement.
Explore the survey 13 minMoney that can move
Change the ruler for a price, the fallback for a bargain, or the rules that let promises become payments.
Explore the survey 19 minThe voltage and the open doors
The same voltage can conceal different numbers of open channels, and different responses.
Read the article 12 minWhen an economy remembers
Nudge a town into a new habit, walk a price index around a loop, and discover how shared risks, exchange, and observation clocks select different probability laws.
Explore the survey 25 minMove to ask a better question
Move a sensor, combine cues, and discover what the next reading can reveal.
Read the article 12 minA compass can hide two destinations
Compare directional populations that share one average but tell different stories.
Explore the survey 10 minWhat a sleeping brain can rehearse
Explore how new observations, fading evidence, and rehearsal change a memory.
Explore the survey 11 minβ-Vale networks: one state, many ways to compute
Explore two pools of neural drive through static, episodic, and spiking networks.
Explore the survey 14 minStrong clocks, a quiet chorus
Discover how strong cellular clocks can cancel the collective rhythm.
Read the article 12 minThe same reach, a firmer hand
Hold the same position with different stiffness, then give both systems the same push.
