An explanation
you can inspect.

Answer, then explain.

Every story gives a direct answer before asking you to explore. We name the parts, explain what causes a change, and keep useful limits beside the example. The related stories follow shared ideas, rather than repeat the same question. Reading trails give these comparisons an order, with an explanation of each connection and its limits.

Use the right kind of source.

A patent documents a described construction. It does not prove that every product works that way, that the invention was first worldwide, or that it achieved a measured improvement. A manufacturer can explain its own design; an industry source can describe a material or production process. Their scope and commercial context matter.

Each story includes section-level source links and a source list. Dates identify the actual editorial publication, not the last software deployment. Source availability and historical claims can change; we link the documents and identify their limits.

Draw the cause precisely.

The diagrams are original code graphics based on the cited mechanisms. Geometry and motion are simplified and not to scale. Arrows show direction, not measured force or flow. Step controls let you compare named states; the same explanation is available in text and in print.

Artwork is illustration.

Object covers and the logo are original AI-assisted artwork. They are not archival photos, laboratory observations, product photographs, or proof of internal construction. We did not copy competitors’ images, text, or branded drawings. Sources are linked for factual checking, not reused as artwork.

Corrections and uncertainty.

Send a correction to dpustovalov.work@gmail.com. Each story includes a report link that adds its title and URL to a draft email. Include the passage, the proposed correction, and a source we can inspect. The link opens your email app; the site does not send a message for you.

When an error is confirmed, we update the explanation and the relevant source record together. A substantial factual or diagram change receives a dated article note and appears on the updates page. Publication dates remain tied to the first public release; modification dates describe editorial changes, not software deployments.

No reader tests or paid traffic results are claimed.

Useful questions. Inspectable answers.

Topic choice combines observed questions, everyday relevance, and available primary evidence. Keyword volume and future readership have not been measured. This working MVP is a way to examine the editorial promise, not evidence that its audience already likes it.
