Engineering Tools
Analytical pipelines extracted from technical papers and complete derivations of structural formulas — each with declared inputs, explicit steps, and a numerical verification case. Three series and a collection of core ideas from patents, open source, ready to use.

Series A — Papers → Tools
Calculation pipelines extracted from peer-reviewed papers. Each node has declared inputs, a formula, and declared outputs. Python notebook included.

Series B — Open Formula
Complete derivations of recurring structural formulas, from first physical hypothesis to final boxed result. Every assumption stated where it enters.

Series E — Engineering Essays
Engineering stories built on peer-reviewed papers. Not a reproduction — an interpretation for curious engineers. Interactive explorers where useful.

Core Ideas — Patents
One physical idea from a patent: a new way of performing a known function. Told step by step, read with its numbers, and derived in full. An explorer to try it.
