How the exhibits are built and checked

Models

Models are generated in code from published specifications such as tooth counts, lengths, angles and timings. No model files are downloaded from third parties. When a real detail would hide the mechanism, the model leaves it out and the article says so.

Numbers

Numbers in the articles are either quoted from a named source or calculated. Calculations are run in code before publishing, and the formula is given on the page so you can repeat it.

Sources

Standards bodies, museums, universities and original papers come first. Encyclopedia articles are used mainly for history and are cross-checked against other sources. Each article lists its sources and the date they were last checked.

Writing tools

Drafts and edits are made with writing tools that include AI. Before an article is published it is checked sentence by sentence against the listed sources, and anything that cannot be supported is removed.

Checks before publishing

• The model is opened on a desktop screen and a phone-sized screen, and every control is tried.
• Numbers in the article are recalculated with the same values the model uses, so the text and the model agree.
• The text is read against a style guide that removes slogans, exaggeration and padding.
• The English and Korean versions are compared so that both carry the same numbers and sources.

Simplifications

Real machines have fasteners, seals, wiring and casings that hide what matters. The model keeps the parts needed to understand the motion and drops the rest. Speeds are sometimes slowed down or exaggerated on screen so the motion can be followed; the article gives the real figures.

Corrections

Reports sent to contact@explorehall.com are checked against the sources. If the page is wrong, it is corrected and the date of the change is shown.
