Computer week

Fifteen computational experiments and one final encounter, made across the week beginning 28 September 2026, around three questions. What is a computer? What is computation? Can computing be a final good, an end in itself, and not only a means to an end?

Each piece starts from something particular (a claim about video models, a car ride, an equation), gives it a form that can answer back, and writes its predictions down before any result exists. Every write-up reports each prediction as held or failed, with the failures explained at the size they are. Every piece has an interactive page that computes in the browser.

Related questions connect the fifteen. Coherence horizon and margin measure what it costs a system to run on its own rule without the world: a painter pays in coherence, a driver in room. Pictorial form gives the exact condition under which a picture of a world has physics of its own. World first and stage put that condition to models that learn only from film, on a gas filmed as smoke and on a stage in linear perspective. Language between asks what two systems can keep coherent through exchange when their clocks, sensing and dictionaries differ. Twenty-six words gives a list of words, from one to reality bites back, forms in one reversible world of bits, and asks what feedback costs a model that is missing one bit of it.

Bowling world tests whether a perfect score minimizes work in a forty-lane business, separating legal histories, material operations and economic objectives.

Causal grammar separates a sentence's sequence, predictive success and intervention meaning in finite Boolean worlds.

The questions the pieces raised and did not answer are collected under open questions.

Changing alphabet lets the units themselves emerge and change: recurring drawings become fragments and compounds, corrective drawings revise them, and new combinations test what they can do.

Second chamber makes the interval before advice available to play: draw with an adaptive companion, change its rule, interrupt it, and repeat in silence.

What counts asks what makes a counting practice work: matching a collection, producing a successor and preserving a shared record can succeed or come apart under different conditions.

Sonic absence composes a finite rule into music and compares a sampled-signal reader with a command-symbol reader. Change spectra, tuning, pulse and memory, or bring your own sound.

When you do not drive lets two renders of one song play each other with no words on the page: a crab-canon dirge, a canon that tightens up seven terraces into unison, and nine spheres that lock into one wheel.
