Saturday is forecast to be 78 degrees and sunny. We did this hike last month but skipped the park because the trail was covered by ice & snow. No such problem this time. We will meet at noon by the Tenleytown metro station and walk down Nebraska to Foxhall Road and back up the Glover Archbold Trail. We will stop at the National Cathedral and then wend our way back to Tenleytown. The starting point for the hike is a hop and a skip from a Whole Foods store with the best peanut butter cookies in the D.C. area. ❶ **What we'll do:** * From the meetup point we'll walk southeast along Wisconsin Ave NW, turn left at Nebraska Ave NW and follow it southwest to Foxhall Rd NW, * We will hook a left on Garfield Ave. and follow to the Glover-Archbold Trail through the woods back to Cathedral Ave. We will cross Wisconsin Ave and stop at the National Cathedral. We will then wend back to Tenleytown via 36th St., 37th St., and Van Ness. * Total distance is around 5 miles and should take about 2 hours, . The surface is paved and slightly downhill on the way out, and a slightly uphill mix of pavement and woodland trails on the way back. This is a fairly easy walk. * [map is for prior version of the hike; update pending] Google map: http://tinyurl.com/y9bthc7a ❷ **How to get there:** * Metro (recommended): The Tenleytown - AU Metro Station is on the Red Line. See the Metro Trip Planner at https://www.wmata.com/ * Driving: If you must drive, the Tenleytown - AU Metro Stationstreet address is 4501 Wisconsin Ave NW, Washington, DC 20016.

Hey Everyone, Here's an update: I am changing the location of our meet up. The current location is a bit small and so I am picking a location, still in the area, that is a bit bigger. Name: Java Loco Coffee & Bubble Tea Address: 7263 Arlington Blvd Suite J, Falls Church, VA 22042 (near McDonalds off Hwy 50) Same time! 4pm Let me know if you have any questions\~

To help us estimate attendance and to see the venue address, please RSVP on Luma!: https://luma.com/af0yjzz6 *A free, public workshop—no technical background needed* ​Artificial intelligence is no longer just getting better at narrow tasks—it’s beginning to look *general*. Many researchers believe we’re entering the early stages of the **AGI transition**: a period where AI systems start to match or exceed human abilities across a wide range of domains. ​This workshop explores what AGI actually means, how to think about it intuitively (without hype or jargon), and what this transition could mean for your job, your relationships, and your day-to-day life—much sooner than most people expect. ​Together, we’ll explore questions like: ​**What is AGI?** ​How do experts define artificial general intelligence, and how is it different from today’s AI tools? ​**Work & Jobs:** ​Which kinds of jobs are already being automated or transformed—and which ones experts believe are most likely to remain resilient? ​**Human Connection:** ​How is AI starting to replace or supplement roles once filled by coworkers, friends, tutors, therapists, and companions? ​**Robots & the Physical World:** ​What happens when advanced AI is paired with rapidly improving robotics—and which parts of the economy could change next? ​**What you’ll get:** * ​A clear, beginner-friendly explanation of AGI and why it matters * ​Real-world examples of how AI is already reshaping work and social life * ​Live demos that highlight both impressive capabilities and emerging risks * ​Interactive discussion and exercises to test your own intuitions about the future ​Come ready to grapple with one of the biggest transitions humanity may ever face—a shift that could redefine not just how we work, but how we relate to each other, find meaning, and navigate a world increasingly shaped by intelligent machines.

(Bus hike) (REMEMBER TO SET CLOCKS FORWARD ONE HOUR FOR DAYLIGHT SAVINGS TIME). We do not often visit this section of the AT, but Snowy Mountain, the central mountain in Michaux State Park, is also its highest. It provides excellent views of Pennsylvania’s rolling mountain scenery. The summit ridge is covered with white quartz, some of which has formed into crystals. Some of the quartz is mixed into conglomerate which makes for many interesting designs as well, which may have led to the mountain's name. Long hikers will begin from Rte. 233, going over Buzzard Peak, with an optional detour to the view at Chimney Rocks. Moderate hikers will begin at Old Forge Rd. at Penn Camp. All hikers will continue past the Deer Lick shelters and, eventually, the Mason-Dixon Line marker, ending up at Pen Mar Park, which provides one of the most expansive scenic overlooks in Southern Pennsylvania. Est.: 13.5 miles, 2200' elevation and 7.5 miles, 1700' elevation. Fare: $33. MD Hikes * **[DC: Near 17th and K St. NW](https://bit.ly/17thandKnu)** downtown (east side of Farragut Square).

Title: What Is Space Density? From Medium Ontology to the Spacetime Constant K Date: March 8 2026 10:00 am - Noon EDT Abstract: Spacetime plays an active role in gravity, wave propagation, and quantum behavior, yet physics rarely treats it as a physical medium with intrinsic properties such as density or inertia. This missing layer creates a major conceptual gap—especially when interpreting large-scale gravitational anomalies that are often attributed to dark matter. In this talk, Lynn will propose a clear conceptual framework for what it means for spacetime itself to possess a density-like property, and Lynn will explain why Unified Field Theory (UFT) naturally encodes this property through the constant K, called the spacetime background inertial intensity constant. Lynn will introduce a space-density constant μₛ as a universal property of space itself—independent of matter, energy density, or gravitational sourcing. However, μₛ cannot be inserted directly into field equations, because it belongs to the ontological level: it describes what space is, not how spacetime responds. To influence dynamics, μₛ must be expressed geometrically. This leads naturally to K, which carries the same physical meaning but operates at the level required by geometric field dynamics. This is a change in representation—not the addition of new physics. This approach provides an alternative way to interpret dark-matter-like effects. Instead of requiring unseen particles, gravitational anomalies can be viewed as consequences of spacetime’s intrinsic rigidity and its global, cumulative response in large coherent systems such as disk galaxies. In local, weak-field environments, standard Newtonian and relativistic gravity remains an effective approximation. The goal of the talk is not to present a final empirical model, but to clarify the physical meaning of spacetime constants and open discussion between UFT and mainstream theoretical physics. Keywords: Spacetime ontology; space density; intrinsic spacetime properties; Unified Field Theory (UFT); spacetime background constant K; geometric response; gravitational coupling; dark-matter-like phenomena Brief Biography 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.

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Our March speakers are Molly Gaines and Zack Parrish, co-organizers of the Secular Education Association: They will share their story of how a small group of Ohio parents grew into a national organization tracking released-time religious instruction and other church–state issues in public schools. The presentation will cover SEA’s early wins and hard lessons, what we’re seeing nationally right now, and how local advocates can play a meaningful role in protecting public education. Attendees will leave with a clearer understanding of the landscape — and practical ways to get involved. Going forward our meetings will be hybrid. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon
