Despite one century of effort, the two regimes remain formally incompatible because neither framework contains a parameter that characterizes the density of space itself. In this paper, I argue that a fundamental density scale—denoted \mu_g—is logically necessary for any unified physical theory. Building on recent geometric models where space evolves as a helical motion, I show that the familiar constants G, \hbar, and c correspond to radial, torsional, and axial components of the same geometric motion. From this perspective, h cannot serve as the universal constant of unification because it measures action, not density. The density constant \mu_g provides the missing bridge: it allows gravitational coupling to be expressed as a property of space itself and reveals that the quantum constant \hbar is also a geometric quantity, proportional to \mu_g c \ell_\Omega^2. This analysis explains why classical and quantum physics have remained disjoint: both lack the necessary density scale. I conclude by proposing that \mu_g is not an additional assumption but a fundamental property of space that any geometric unified field theory must incorporate. References to the prior geometric theory by Zhang Xiangqian and Xu Yuchuan are included to situate this work within the emerging framework of helical-space physics. Speaker: Lynn Lou Beran is a Senior IT Security Analyst and an author, translator, and editor working at the intersection of science, engineering, and communication. She translated and edited multiple editions of Zhang XiangQian’s Unified Field Theory and co-authored recent manuscripts developing a geometric, motion-based view of physical reality. Lynn’s broader work focuses on making advanced ideas accessible without sacrificing rigor, and on connecting conceptual insight to testable predictions and practical tools.

**Life** Gottfried Wilhelm Leibniz was born in 1646 in Leipzig. He had access to a substantial library early in life and is said to have taught himself Latin to read the Church Fathers and Latin Classics. He attended universities in Leipzig and Altdorf, earned a doctorate in law in 1667, turned down a faculty position, and went to work for the Elector of Mainz. In 1672 he had the opportunity to visit Paris to discuss his Egypt Plan, in which France would invade Egypt and leave Germany and the Netherlands alone. There he met several leading French thinkers, including [Nicolas Malebranche](https://www.britannica.com/biography/Nicolas-Malebranche) and [Antoine Arnauld](https://iep.utm.edu/antoine-arnauld/), and studied mathematics under [Christian Huygens](https://www.britannica.com/biography/Christiaan-Huygens) (discovering integral and differential calculus after about three years). He created a calculating machine and, based on this work, was made in 1673 a member of the Royal Society. In 1676 he began working in the court of the Duke of Hanover. He spent much of his life promoting science, libraries and learning and was the first president of the [Royal Prussian Academy of Sciences](https://en.wikipedia.org/wiki/Prussian_Academy_of_Sciences). Leibniz made contributions to not only mathematics but physics, theology, and philosophy. He sought to reconcile Catholicism and Lutheranism and, in his own way, modern science and philosophy to certain Aristotelian ideas, such as the substantial form and final cause. He died in Hanover in 1716. **Themes** Leibniz is regarded, along with Descartes and Spinoza, as one of the most important rationalist philosophers of his age. He wrote a work in response to John Locke arguing that some principles or ideas are in some sense innate. In metaphysics, he asserted the principle of sufficient reason, which says that things happen when there is more reason for them to happen than not, and claimed that, strictly speaking, all true statements are analytic (e.g., it can be truly predicated of Ceasar *a priori* that he crossed the Rubicon). Unhappy with atomistic and other accounts of substance, he argued that monads (dimensionless, soul-like entities) are fundamental, reflect everything that has ever happened or will happen, and are in sync with each other through a pre-established order chosen by God. From the conclusion that God has chosen this world, and that God can only choose the best, Leibniz famously claimed that this is the best of all possible worlds. The system Leibniz set up would seem to leave little room for human freedom, but he tried to argue that people were nonetheless free in some sense. Right or wrong, his views are complex and interesting. **Works and This Month's Reading** Leibniz wrote so much that the critical edition of his collected works, underway for several decades, remains unfinished. Much of this output consists of short works—letters, journal articles—rather than a magnum opus. His only book-length statement of his philosophy published in his lifetime is *Theodicy*. His other major works include *Discourse on Metaphysics*, *Monadology*, and *New Essays on Human Understanding*. Except for *Monadology*, our readings this month are not from his most famous works; however, the selections in the *Shorter Leibniz Texts* are helpfully arranged, cover many of Leibniz's main claims, and, because the selections are short, can be read in coherent, manageable chunks. **Readings** · [The Shorter Leibniz Texts (Strickland)](https://www.amazon.com/Shorter-Leibniz-Texts-Collection-Translations/dp/0826489516/) · [Monadology (Google Books, pp. 215-271)](https://www.google.com/books/edition/The_Monadology_and_Other_Philosophical_W/0IARAAAAYAAJ?hl=en&gbpv=1) – The Strickland version listed below is a good alternative. Both have more footnotes and explanatory text than text from Leibniz. **Optional** · [Gottfried Wilhelm Leibniz, IEP](https://iep.utm.edu/leib-ove/) – Summarizes Leibniz’s thought based on *Discourse on Metaphysics*, *Monadology*, *Theodicy*, and *New Essays on Human Understanding*. · [Leibniz's Monadology: A New Translation and Guide (Strickland)](https://www.amazon.com/Leibnizs-Monadology-New-Translation-Guide/dp/074869322X/) – An alternative to the version on Google (above), this version also has relevant selections from *Theodicy*. · [Leibniz: Philosophical Essays](https://www.amazon.com/dp/0872200620/?) – Contains Discourse on *Metaphysics*, *Monadology*, the Preface to *New Essays on Human Understanding*, and several other short works and letters. · [The Philosophy of Spinoza & Leibniz (YouTube) - Magee & Quinton, 1987](https://www.youtube.com/watch?v=C7n7wfQOGaI) · [The Essence of Calculus (YouTube) - 3Blue1Brown](https://www.youtube.com/watch?v=WUvTyaaNkzM) \- Quick intro\. · [Mathematical Treasure: Leibniz's Papers on Calculus (MAA)](https://old.maa.org/press/periodicals/convergence/mathematical-treasure-leibnizs-papers-on-calculus) – If you’re curious what Leibniz’s calculus looked like. · [Mathematics - 19th Century, Algebra, Calculus | Britannica](https://www.britannica.com/science/mathematics/Mathematics-in-the-19th-century) – History of math, with some math.

Socrates Café are gatherings around the world where people from different backgrounds get together and exchange philosophical perspectives based on their experiences, using the Socratic Method of inquiry (asking and answering questions). Today, there are hundreds of such gatherings, coordinated by volunteers, worldwide. Though this may be considered a "philosophy" group, there are no rules as to what is discussed. Usually, the topics revolve around social concerns, morality, and the first principles of things. Please post any questions you would like the group to consider on the meetup event's page; in the comments section. Several days before the meetup I will post a link to a voting form in the comments section, and everyone can vote on their preferred questions. The questions with the highest and second highest number of votes will be discussed. Hope to see you there! -Brian

**⚔️ Introduction to Wargaming & Painting Miniature Soldiers at The Arcane Foundry ⚔️** Join me in **The War Room at [The Arcane Foundry](https://share.google/S5i6DYJnJteHWeKtd)** for a laid-back evening of hobby talk and tabletop fun! For just **$15**, you’ll get a **3D-printed regiment of 20 high quality resin models** of your choice to paint — a **$40 value!** Bring your creativity, relax, and let’s make something awesome together. **Choose one from Below:** * 20 Orc Warriors * 20 Empire Soldiers * 20 Dwarf Warriors * 20 Elf Spearmen Step into a world where strategy meets artistry — and where every painted figure tells a story of battle, honor, and imagination. Join **Daclaud** at **The Arcane Foundry** for an evening that introduces newcomers and enthusiasts alike to the timeless craft of **tabletop wargaming** and **miniature painting**. My own journey began with a fascination for fantasy — knights in armor, grim and hardened warriors, and monstrous creatures locked in epic battle. That passion led me to **Dungeons & Dragons**, where I painted my first **Basic Heroes set** and felt the spark that comes from bringing a character to life in miniature form. Not long after, I discovered **Warhammer Fantasy** and **Warhammer 40,000**, and I was hooked. The vision of vast armies clashing across the table — each unit meticulously painted, each story unfolding through dice and imagination — became my creative obsession. During this event, we’ll explore the **origins of wargaming**, from its early military simulations to the richly detailed worlds of modern tabletop battle systems. You’ll learn how to **build and customize your own armies**, paint your first figures, and experience the joy of turning strategy and storytelling into a hands-on art form. Whether you’re drawn by the lore, the hobby, or the thrill of commanding miniature legions, this introduction will open the gates to a world that has captivated hobbyists for generations. **🎨 RSVP today and join us at The Arcane Foundry — where every brushstroke and battle tells a story.**

**Caller: Gaye Fifer** **Band: Hot Coffee Breakdown** **Big Scioty Contra Dance** **temporarily returning to our long ago location for Jan-March - First Congregational Church, 444 E. Broad St., Columbus 43215** WHAT IS CONTRA DANCING? Picture the Grand Ball scenes like you’ve seen in period films such as “Pride and Prejudice”, where the dancers are lined up in long lines, across from each other. That’s English Country Dancing, the predecessor of contra dancing. Now, add moves like “swing your partner” and “do-si-do,” like you’ve seen in square dancing. Set it to fabulous, high energy, live music with fiddles, guitars, percussion and more, alá “Riverdance.” Finally, set the whole scene down in the middle of Woodstock, with a hip, groovy atmosphere, a bit of tie-dye, and hints of counter-culture attitude. THAT’s Contra Dancing! Wear cool and comfortable clothes (you will get warm) and clean shoes that won't mark up our nice wood floor. Be sure to come for the beginner's lesson from 7:30 - 8:00, followed by dancing 8:00 - 10:30. All dances are taught; we will help you learn! Beginners always welcome, no need to bring a partner. Cost is $10.00 adults, $5.00 ages 12-26. Under 12 free. Free parking in church lot. For more information contact me or check out our website: [www.bigscioty.com](http://www.bigscioty.com/) Please bring your own refillable water bottle. Snacks to share are always welcome!
