We'll use this time to meet new GRASP members and catch up with those we already know! Look for GRASP table flyers and Eli's GRASP shirt to easily find the group. This restaurant is a fast-casual format meaning it's easy to order and pay individually! Adult beverages are available and you can expect entrees in the $15 range. The [Torchy's Tacos menu is here](https://torchystacos.com/menu/) and they offer a wide variety of tacos, burritos, salads, and excellent sides. In living by their Damn Good mantra, they’re constantly innovating to ensure they’re delivering the tastiest tacos, queso, and margaritas in the game. Their Taco of the Month promotions allow them to provide unique tacos to Taco Junkies year 'round. The ingredients make the meal. That’s why they responsibly and ethically source every single ingredient, down to the jalapeño. From there, they work hard to whip up the best damn tacos, cooked to order, just the way you like 'em.

Twenty years ago, George Mason University professor Zachary Schrag published the definitive history of the Washington Metro: "The Great Society Subway". With the 50th anniversary of the system coming up at the end of March, TEDC founder Will Rice will make a presentation based on the book. Many elements and conflicts combined to create the Metrorail we now enjoy: a trust in big government projects; the battle over urban highways; the emerging D.C. home rule movement; Black-white relations; and the balance of city and suburban interests. Come learn more about it all! Also at the meeting: pick up your pre-ordered Metro 50 t-shirt (for new purchases, an order form is [here](https://transitenthusiastsdc.wordpress.com/wp-content/uploads/2026/01/t-shirt-order-form.pdf)). And hear the latest news on how we plan to celebrate the system's golden anniversary on March 27!

AI coding tools are no longer just smart autocomplete. They can act like background teammates working in parallel. This working session will unfold in two parts. First, Lee will demonstrate how to orchestrate multiple AI agents simultaneously using GitHub Copilot. He will show how to isolate work across branches and coordinate independent tasks such as running tests, generating a UI, and building core logic using Git worktrees. In the second half, attendees will experiment together by tackling Conway’s Game of Life using parallel agent workflows. Rather than a polished demo, this will be a live coding experiment where participants are encouraged to use their own tools. You will see what works, what breaks, and what it really takes to manage concurrent AI workflows effectively in real world development. NOTE: Ideally bring a laptop with a Copilot/Claude/Cursor/etc account

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.

(\*Multiple Meetup groups are co-organizing so RSVP's shown are just a small % attending. ABOUT: Do you know more than 6th Graders! Here is your opportunity to have some fun playing our Live interactive trivia game (Categories will be History, English/literature, Geography, Science, Math, Potpori). HOW IT WORKS: You can attend via a computer & Webcam or Smartphone/Ipad/Tablet. This completely online event will be LIVE and you will be able to see and hear the other participants while playing. In addition you get to meet and interact with other participants. At game time, your host will read off Trivia questions. Your goal is to come up with the right answer to each question and write it down on your paper. Once the round is over (about 6 questions), we will go through the answers and determine who had the highest score for the round. They will get a raffle ticket for a chance to win a prize at the end of the event. We will have multiple rounds of play and have a system to also virtually introduce you to other participants. HOW DO YOU FIND THE VIRTUAL ROOM: After you purchase your ticket, you will get a confirmation with the zoom link ON DAY OF THE EVENT. RSVPS ON HERE ARE NOT REFLECTIVE OF ACTUAL ATTENDANCE as this is a multi group event. **\*TO ATTEND REGISTER AT - [https://www.socialevents123.com/event-details.aspx?id=13302#tix](https://www.socialevents123.com/event-details.aspx?id=13302#tix)** Cost: $15- $20 depending on how early you register. **For more fun events:** **Follow: [https://www.eventbrite.com/o/new-york-city-social-events-10797526283](https://www.eventbrite.com/o/new-york-city-social-events-10797526283)** **Click: [https://dljparty.ticketleap.com/](https://dljparty.ticketleap.com/)**

THIS GAME IS BASED ON AN OLD GAME , SO MOST OFTEN YOU WILL NOTICE THAT PEOPLE ( THE FOUNDERS) ARE ADDED BEFORE THE RSVP EVEN OPENS. After that, few spots are available for first reserves and the Host has the right to choose the added people from the wait list (Based on dependability, punctuality and cooperation) ***No wait list show ups*** No-shows will be taken seriously and you lose your privilege to RSVP the next game. This is an early game, so you have to cancel the night before. If you cancel late, it will be considered no show. Please wear turf shoes (no cleats) in this field. Please use a clear profile picture so it is easier for us to know each other. if you don't have a clear picture, the host might cancel your rsvp. If you plan on playing with us , keep in mind we collect yearly donations (Collected once a year ,$25). You can zelle me (3189143325) or Venmo(@Aladdin-Alayoubi) or give cash.

This month, we'll have a recorded talk, followed by discussion, on API design and single-header libraries. How should we structure and program libraries to impose as few usage constraints as possible? We’ll look at [the STB libraries](https://github.com/nothings/stb) and other examples as case studies. We're still at the West End Library - see the location in the sidebar for details. **Agenda:** \- 2pm \- 3pm: Library discussion \- 3pm \- 4pm: Open\-ended discussions\, presentations\, etc\. \- 4pm \- whenever: We'll go get food nearby\! **What we do** Presentations on lower-level, foundational programming topics, ethical software, knowledge sharing, mentoring, and discussion. **Who we are:** We are all about handmade software. Rather than focus on frameworks, heavy abstractions, and buzzwords - we typically create projects or research topics that build an understanding of foundational computing concepts, essential data structures, and hardware/software interaction. **What to bring?** Bring a laptop, project, or just a curious mind. If you're not sure you're ready to contribute, don't worry: we're all here to share our passions and hone our craft. **If you arrive late:** Please enter the room quietly as to not disrupt anyone that is presenting. You can take any empty seat.

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

**Our March pick is *God of the Woods* by Liz Moore.** **This month’s novel is an award-winning literary mystery that blends family drama with psychological suspense. It explores women’s voices and relationships while delivering an exciting, eerie, and deeply suspenseful story. The book is 576 pages in print or 14 hours and 35 minutes on audiobook.** Early morning, August 1975: a camp counselor discovers an empty bunk. Its occupant, Barbara Van Laar, has gone missing. Barbara isn’t just any thirteen-year-old: she’s the daughter of the family that owns the summer camp and employs most of the region’s residents. And this isn’t the first time a Van Laar child has disappeared. Barbara’s older brother similarly vanished fourteen years ago, never to be found. As a panicked search begins, a thrilling drama unfolds. Chasing down the layered secrets of the Van Laar family and the blue-collar community working in its shadow, Moore’s multi-threaded story invites readers into a rich and gripping dynasty of secrets and second chances. It is Liz Moore’s most ambitious and wide-reaching novel yet.
