One Grain

The animated version could not start on this device, so here is the story as text.

Nature

Deep underground, molten rock cools slowly. Quartz begins to crystallize.

The crystal is locked inside granite, waiting for uplift and erosion.

Weathering frees the grain. Running water carries it downstream.

Waves sort and tumble it, moving it along the shore.

Wind lifts it in short hops, rounding and frosting its surface.

Buried. Cemented into stone. Lifted. Freed. Buried again, until heat and pressure turn the sandstone into quartzite.

The cycle breaks. Silica-rich rock is taken from the ground.

Quartz meets carbon at extreme heat. Oxygen leaves; silicon remains.

Converted, distilled, deposited again. The silicon becomes hyperpure.

Melted above 1,414 °C, it is drawn upward from a single seed.

The ingot is ground, sliced, etched, and polished into mirror-flat wafers.

Light projects a pattern onto a photosensitive layer.

Layer by layer, patterns become transistors and the connections between them.

Millions of years to arrive. Nanoseconds to act.

Silicon computes. Pixels turn its signals into light.

Even the glass in front of the pixels is mostly silica.

One plausible journey; real timescales vary widely.
