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.

Celebrate the passing of the seasons and the return of the sun on our Annual Sugarloaf Winter Solstice/Poetry Hike, an Adventuring tradition since 1997. This year we're able to do this hike on the actual day of the Solstice--Sunday, December 21, 2025. After varying the routine a bit last year, we will return to our usual 7-mile circuit, with lunch at White Rocks and climbing to the summit near the end. Expect some climbing and a variety of terrain, including some rocks. During our White Rocks lunch, we’ll share favorite poems in honor of the passing of another year. Meet at 9 a.m. at the Grosvenor-Strathmore Metro Station. So we can plan accordingly, please answer the Meetup questions about whether you’ll be meeting us at Grosvenor-Strathmore or Sugarloaf, and whether you can be a carpool driver. Those wishing to drive directly to Sugarloaf should contact Chris Craig for directions and time; you can email him directly at [ccraig@laurellodge.com](http://mailto:ccraig@laurellodge.com/). We'll all rendezvous by 10 a.m. in the West View parking lot—the one at the top of the drive. Bring a bag lunch (we will NOT be stopping at a Sheetz on the way), water, sturdy shoes, the $5 Adventuring fee, $5 to reimburse your carpool driver — and most important, a poem to share on the mountaintop (your own or someone else's). \>\> Please [click here](https://adventuringlgbtq.com/Adventuring_Release_Form.pdf) to review our release form.

Apostolic Word Of God Church Freewill Prophetic Worship Service. Apostle Dr. David and Prophetess Dr. Marguerite Carter are inviting you to join our Sunday Worship Services. Optional Join Zoom Meeting https://us02web.zoom.us/j/83705862326?pwd=OVZHMFB6U0lrOUlIT1gxSDZ3c2w1QT09 Meeting ID: 837 0586 2326 Password: 667084 Optional one tap mobile +13017158592,,83705862326#,,,,,,0#,,667084# US (Germantown) +13126266799,,83705862326#,,,,,,0#,,667084# US (Chicago) The Purpose Of Our Worship Of God The purpose of our worship is to glorify, honor, praise, exalt, and please God. The nature of the worship God demands is the prostration of our souls before Him in humble and contrite submission. Jesus says in John 4:23-24, "But the hour is coming, and now is when true worshippers will worship the Father in spirit and in truth, for the Father is seeking such to worship Him. God is Spirit and they that worship Him must worship Him in spirit and in truth."It doesn’t say we can worship God any way we want, but we "must worship Him in spirit and in truth". The word "must" makes it absolute. There is no other way we can worship God and be acceptable to Him. God seeks true worshippers, and He identifies them as those who "worship Him in spirit and in truth". Worshipping God in spirit means that it must be done from the heart. Worshipping God in truth means that it must be done according to God has specified in the Bible. Come with Expectations: Expect to experience the Presence of the Lord. Follow the leading of the Holy Spirit and flow in the spirit. Expect "Soaking Time" This is your personal time seeking the Lord while listening to prerecorded music, as directed by the Holy Spirit. Come 15 to 30 minutes early for soaking time. Expect an atmosphere of freedom to worship and liberty in Christ Jesus. Expect the Holy Spirit to administer Spiritual Gifts in the Body of Christ: The Word of Wisdom, Word of Knowledge faith, gifts of healings, working of miracles, prophecy, discerning of spirits, divers kinds of tongues (languages), interpretation of tongues (languages), 1 Corinthians 12. Expect singing and praying in the spirit with understanding, 1 Corinthians 14:15 Expect to be filled with the spirit, speaking to yourselves in psalms, and hymns, and spiritual songs, making melody in your heart to the Lord. Giving thanks always for all things unto God and the Father in the name our Lord Jesus Christ. Ephesians 5:18-20 Expect anointed teachings/preaching of the Word Of God. Expect to lay prostrate while seeking the Lord (bring a throw blanket). Note: The above is freely administered by the Holy Spirit, subject to change, and is not all-inclusive. There is much more, but cannot be written here. Remember God sent you here for a purpose. Blessed be God and Father of our Lord Jesus Christ, who has blessed us with all spiritual blessings in heavenly places in Christ. Ephesians 1:3 We love you in Jesus's name.

Let's enjoy the current warmer weather with a hike this Sunday in DC's Rock Creek park! This one’s for all the car-free DC folks, those who want an short morning drive with easy parking, and anyone who wants to explore one of region's great urban parks. This is a moderately challenging hike due to its length (rather than elevation). We’ll move at a steady 2-3 mph pace with breaks as needed. Water and bathrooms are available at the start, and may also be available a few miles into the hike, but please carry a minimum of 1L with you. Start location: we’ll meet at Picnic Grove 24 across from Rock Creek Tennis Center [https://maps.app.goo.gl/wUMV6UqH7GKsDBbA8?g_st=ic](https://maps.app.goo.gl/wUMV6UqH7GKsDBbA8?g_st=ic) Route: [https://www.alltrails.com/explore/custom-routes/custom-route-ba011fd](https://www.alltrails.com/explore/custom-routes/custom-route-ba011fd) Parking: Free and plentiful Transit: Several buses go past this location on 16th Street. You can pick them up from Silver Spring metro (red line) or various metro stations in downtown DC. Bikeshare: the nearest dock is at Colorado Ave & Longfellow St NW per Google. Meet time: We'll meet at 9:30 am at the location noted above and, after intros, start hiking the trail shortly afterwards. There is no official after hike meal planned. For those that which to gather informally, the hike leader recommends Moreland's Tavern, which is an easy walk from our meeting point: [https://morelandstavern.com/](https://morelandstavern.com/lunch/) CARPOOLING: Although this is one of our rare public transportation-accessible hikes, we encourage those with cars driving in from outside DC to be willing to carpool - you're the ones who make LMH great! If you're a driver that is willing to drive, please post a comment on the event page with the following information: (1) Number of seats (2) Meeting location (3) Meeting time As a rider, please comment on the driver's post to take a seat or post in the comments that you need a ride so a driver can find you.
