ζήτημα — a question worth seeking an answer to

Every problem is a question the world is asking.

Real problems from every place, each tied to its sources. Sit with one. Understand it. Then build what solves it.

The index holds 130 problems, traced to 99 sources. They wait for the first voice to say which should be solved.

The pantheon

Wisdom to see it. Craft to fix it.

Old emblems for the work of solving real problems for a community, from Greek, Indian and Egyptian traditions. Each keeps watch over a part of Zetema.

Wisdom and learning

Seeing a problem clearly, and telling truth from noise.

  • Athena’s owl

    Greek goddess of wisdom and craft; her owl sees in the dark.

    Weaving: many threads, one cloth.

    Community

The council

They asked hard questions too.

Each portrait is drawn from the shape of a thinker’s work, not their face. Their words travel with the problems and kits they fit.

Socrates

Athens · 5th c. BCE

Asked until the answer held. A spiral of questions.

Gārgī Vācaknavī

Videha · Upaniṣadic age

Asked what the world is woven upon. Warp and weft.

Āryabhaṭa

Kusumapura · 499 CE

Taught that the earth turns. Orbits within orbits.

Hypatia

Alexandria · c. 400 CE

Taught the conic sections. Circle, ellipse, parabola.

Pāṇini

Gandhāra · c. 4th c. BCE

Wrote a whole language as rules. A lattice.

Archimedes

Syracuse · 3rd c. BCE

Moved the earth, in principle. The lever and the spiral.

How it works

I · Seek

Every problem is drawn from public sources, and every claim points at its quote. What cannot be quoted is left out.

“Lead me from the unreal to the real, from darkness to light.”

असतो मा सद्गमय। तमसो मा ज्योतिर्गमय।

asato mā sad gamaya, tamaso mā jyotir gamaya

Bṛhadāraṇyaka Upaniṣad · 1.3.28

II · Gather

People who live a problem say they want it solved and what it is worth to them. Nobody is charged.

“That which is not good for the swarm, neither is it good for the bee.”
Marcus Aurelius · Meditations 6.54 (tr. G. Long)

III · Build and verify

Builders take up a problem and ship. It counts as solved only when the people who have it say it worked.

“If I have seen further it is by standing on the shoulders of Giants.”
Isaac Newton · letter to Robert Hooke, 5 February 1675/6
