It is supposed to be 60 degrees Thursday. Let’s take advantage with a walk at Brookside Gardens. We will meet to the right facing the visitors center. If anyone is interested we can go to lunch afterwards.

• What we'll do On https://blackecon101.podbean.com/ Thursdays at 6 pm. discussing the economy....

For the Wednesday run, let's meet at 1750 Crystal Dr (Entrance by Morton's Steakhouse) before walking over to the Crystal City Water Park and run on the Mt. Vernon Trail alongside the scenic Potomac River. LOCATION: Meet at 1750 Crystal Dr (Entrance by Morton's Steakhouse). Link to location on map: http://i.imgur.com/3yN0lwN.jpg NOTES: Photos taken during the event may end up on Instagram, Meetup, Strava and similar platforms. Let's meet at 6:50 PM, leaving by 7:00 PM. We will do 50 minutes, so 25 minutes out and 25 minutes back. You're welcome to do more if you'd like. Just before the run we decide whether we'll go NORTH (DC) or SOUTH (Old Town) on the trail. Once we're done, we meet back up at the Crystal City Water Park area. After the run please feel free to hangout and socialize with the group or join us at Highline RxR in Crystal City (National Landing) for a beverage and/or food. https://g.co/kgs/AErMQZ All paces are welcome! We run by time, not speed so bring a watch to monitor your time and turn around at the halfway time point. If you need to run/walk, that's ok! We average anywhere between 7-13 minute/per mile pace. First Time? Start out slow to find someone around your pace. The different paces tend to automatically gather, so you won't be alone! Metro: Crystal City on Blue/Yellow lines, 2 blocks from metro exit. Parking: There is plenty of free parking inside the garage directly across from the Crystal City Water Park. Post-Run: A lot of times we have a little social outing after the run. You can bring a change of clothes if you'd like (though most people just go as is). We'll finish up the run, meet back at the Water Park, pick up our wallets and walk to wherever we decided to go for a beverage and/or food. If you have a suggestion for a place to check out, let us know!

We are at Lost Generation Brewing. Outside food is permitted + there's a food truck outside.

Our "monthly meeting" is happening again this weekend! Please join us at the highly rated CIRCA restaurant just steps from the Foggy Bottom metro station. Our reservation is on the covered patio this time, and the weather is supposed to be nice! Enjoy small plates, a full meal, salads, cocktails, beer on tap or whatever you'd like best on a Sunday afternoon. Of course, great conversation, laughs and in-person social time with great FFF>50 friends is the best part! Hope you can join! Note: This and other FFF>50 events will soon be permanently shifting to our walled-garden playground on the Mighty Networks platform, please sign up [here!](https://community.fff50.org/share/dbWb9iJu5XwSN2TR?utm_source=manual) If it's full with a waitlist here you can get a spot on Mighty!

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.

Let's meet up for Pizza and Ping Pong at Comet in DC Fun event to play ping pong and eat some good pizza. WE can play some games too Parking lot in the back and street parking available Guests must be over 50 This is a non reservation event. It's time to RSVP for a fun evening.

A favorite of the DMV's swing dance community, the Rock-A-Sonics play a mix of Rockabilly, 50's rock and country, and Western swing. Frontman Willie Barry's pure tenor is accompanied by a group of very talented musicians. Tommy Joe's in downtown Bethesda occupies the second and third floor of corner building. Bands play the second floor and there's no cover. It's easily accessible by metro or car (I use parking garage 36 Auburn- Del Ray).

Join us for conversations that go beyond small talk, diving into topics like the shifting nature of spirituality, the challenges and joys of midlife transitions, the impact of culture and capitalism, and the search for meaning in art, travel, and daily life. Our gatherings are about genuine, thought-provoking dialogue, with no set leader or strict agenda—just an open space to share ideas, perspectives, and experiences that matter to us. The direction of the discussion is shaped by everyone who shows up, making each event unique and enriching.
