Welcome to a site devoted to the quiet beauty of geometry —
Poly-Geometry

This is a personal site, shaped over many years with the generous help of fellow geometers — especially members of the QPG Forum.

Poly Geometry is a new branch of geometry, shaped by configurations of n points, n lines, and curves of degree n — a structure echoed in the name Poly.

Below are two examples that illustrate the spirit of Poly Geometry — inviting both curiosity and insight.

 

Every n-Point configuration has its own barycenter:

Every polynomial curve of degree n can have up to n intersection points with a line:

Latest Updates & News

November 2025 — Site Relaunch & Treasury Launch

The site has undergone its first complete redesign since its launch 14 years ago, bringing together all previous sections of encyclopedias into the unified EPG.

What’s new:

  • EPG-Treasury — contributors can now archive and share related articles.
  • Annual Journals — forum contributions are curated for long-term reference.
  • Downloads — a range of downloads has been added:
    • All encyclopedia sections are available as PDF reference volumes.
    • Extensive macro sets for Cabri II to support further research.
    • Specialized Mathematica notebooks with modular tools for exploration.

I intend to post occasional updates here about ongoing developments.
