P(A|B)posterior
observation / 01
Belief updates when evidence arrives. The prior bends toward the likelihood, and what we thought we knew reshapes itself in the light of what we observe.

Everything clusters around the mean. Heights, test scores, measurement errors — nature's favorite shape is this gentle rise and fall, the Gaussian whisper that most things are ordinary.

When the equation is unsolvable, simulate. Throw enough random darts at the problem and the shape of the answer emerges from the scatter — order born from chaos, signal from noise.

In a room of just twenty-three people, the odds of a shared birthday exceed fifty percent. Our intuitions about coincidence are reliably, beautifully wrong.
