PDF Library

August 2025

The original PDF library page from the old site couldn’t be meaningfully recovered from the Wayback Machine — the only archived snapshot captured Internet Archive’s own site chrome, not the actual page content or the PDF files themselves. Two of the original PDFs have since been located and are hosted here directly:

• PBT Model Reference Guide — plus the original matplotlib-generated flux-shadowing figure. Currency note (2026-07-31): this PDF is a dated snapshot regenerated on 2026-07-21 and is no longer identical to the Reference Guide page. The live page has since gained entries for Papers 14–17 and carries later corrections. Nothing in the PDF is known to be wrong — it was accurate when built, and is labelled with its own date on its cover — but the web page is the current version and should be preferred where the two differ.
• Formalizing Push Pressure Theory — the source document for the formally published paper on OSF and ai.viXra.org, including all three original figures. Same currency note applies: dated 2026-07-21, predating Papers 14–17.
• Atmospheric & Vacuum Pressure Conversion Table — a real working engineering reference, not PBT-specific; see Practical Applications for the full explanatory guide.
• DC to AC Across the Spectrum — Matthew’s own mapping of DC-to-AC conversion from infrasound through visible light; see Practical Applications for the full explanatory guide.

If more of the original PDFs turn up, they’ll be added here directly. Once Google restores access to the locked Blogger blog, the rest of what was originally linked from this page can be reconciled against it.
