***In Person Location:*** Rockville Library, second floor meeting room (Collaboration Room 3). We are experimenting with a new virtual join link - [https://meet.jit.si/mocomakers](https://meet.jit.si/mocomakers) If you can make it in person, that's always recommended! Let's resume repeated full end-to-end testing cycles and continue to iterate our design and resolution. We are getting close. Our community is building (and documenting for other teams) how to build a scanning tunneling microscope using a mix of common and 3D printed parts. This will allow us to scan and visualize a single atom - an ambitious we are doing over the course of a few months. The MoCo Makers community is one of the most innovative and competent groups in Maryland, and we've done everything from [publishing cancer research](https://pubmed.ncbi.nlm.nih.gov/38136356/), to [launching products](https://www.kickstarter.com/projects/gotim/cozy-curvy-multi-contour-pillow), [winning grants](https://covidinfocommons.datascience.columbia.edu/awards/2014255), and inspiring thousands. Now our biggest challenge yet has appeared. We are building a Scanning Tunneling Microscope, that will allow us to scan and visualize single atoms. Does it sound hard? Perhaps.. However! I have every confidence that we are now operating at a level were we can take on this mean, cross-functional project. We continue to build on our past successes, and a key technology we previously applied was increasing the signal of small voltages using OpAmps - which we did during our custom pH Probe project - [https://www.mocomakers.com/ph-probe/](https://www.mocomakers.com/ph-probe/) \- That technology is exactly what we need to get this machine working\, and at a high precision\! To get a better idea of what we are doing, see our reference project here: [https://www.youtube.com/watch?v=7N3OqTEq08g](https://www.youtube.com/watch?v=7N3OqTEq08g) All starting CAD, code, and reference files should exist. However, let's be the first Maker community to document the build process and share it with learners around the world. We have a bit over $2,000 in materials costs, so if you want to sponsor this project, and get banners at events with 20K attendees, and access to our email broadcast of 30K members, please contact matt@mocomakers.com We are also open to university, lab, or community partnerships so feel to reach out if you want to be part of this project. Together, we can do incredible things. ***In Person Location:*** Rockville Library, second floor meeting room (Meeting Room 3). To Join Virtually: https://meet.jit.si/mocomakers

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.

Zorba's Cafe on Thursdays! We will be on the 2nd floor, or if the weather allows, we will be sitting outside at a table in the street. If you don't see anyone on the 2nd floor and the weather is favorable, it means we're sitting at the table in the street. Уважаемые участники группы! Информация для тех, кто еще не посещал наши встречи - обычно подписывается меньше людей, чем приходит на встречу, "старожилы" привыкли к тому, что записываться необязательно, и просто приходят в любое удобное для них время с 5:30 до 8 часов. Так что не стесняйтесь, записывайтесь на встречу! Welcome to the old venue! Old - since we used to get together at Zorba's Cafe for many years. Come to the 2nd floor. 1612 20th St NW, Washington, DC 20009 This is very close to Metro Dupont Circle station. This is the same place where we got together every Thursday evening for many years before 2015. Everyone is welcome, but please keep conversation in Russian only. For many of us, this is our only chance to practice our Russian. There are happy hour prices available. Timing: Someone is usually there by 5:30, but it sometimes takes the organizers till 5:45 or so. If you get there first, please wait - we will be there! And people are usually there till at least 8. So if you can't make it right at the beginning, that is perfectly fine to arrive late! RSVP's: I encourage you to RSVP. But please know that many people don't RSVP. So it may seem like only 3 people are planning to attend, but have no fear, we usually have a good-sized fun group! (And we almost always have newcomers. So if you are planning on coming for the first time, you most likely won't be the only one.) Also, when the weather is nice we are frequently sitting outdoors. So if nobody is on the second floor, just look for the group speaking Russian at tables out on the street. And to say again - we have often had only 3 or 4 people RSVP but have 15 or so show up. So don't worry about that. See you there! Questions? Check our FAQ (http://www.meetup.com/russki-razgovor-dc/pages/Frequently_Asked_Questions/) page.

Join us for an hour of writing! We’ve discovered that it’s strikingly helpful to write with other writers. See if it’s true for you at **7:00 PM on Wednesday evenings.** Edit: As of January 7, 2026, we will be back at Starbucks! Be it a book, blog, script, essay, dissertation, resume, melody, poem or just plain work stuff, you are invited to write it with us. No one will see what you've written or give you unsolicited advice. Instead of just thinking about writing, come and get some real writing done. **We'll meet inside the coffee shop**. Please buy something to ensure we're welcome back. Sit down anywhere, but let me know you're here so we can introduce ourselves and check in before and after writing! (I'll be the one with the sign.) **SCHEDULE:** 7:00 - Quick introductions 7:20 - Timer starts: write for 1 hour 8:20 - The End: chat, take off, or keep writing Writing is very solitary. Connecting (and sometimes even commiserating) with other writers is a cool thing. BEING LATE IS OKAY: just show up and get settled, then check-in with me after the session. If you were on time, please be willing to make room for the friendly latecomer. Happy writing and I look forward to seeing you! **What Should I Bring?** Whatever you need to be able to write! Note that outlets are limited, so please make sure your devices are charged. Bring earbuds/earplugs if you want to block the overhead music or the conversation by other patrons. **Other Important Details:** Starbucks has WiFi. TRAVEL / PARKING: The shopping area is about a twenty minute walk from the College Park or P. G. Plaza/Hyattsville Crossing Metro Stations. There's also a bus stop right outside the shopping center on Baltimore Ave. Parking is free. SEATING INFORMATION: Seating is first come first serve. I'll try to grab a table, but be prepared to sit down anywhere. FOOD GUIDELINES: Tea, coffee, and light food are available at the coffee shop. Please thank our hosts by purchasing something to drink.

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.

ike Turkey Run Park- Pho Lunch, VA Sunday March 8 With winter weather receding, this is a great way to fight cabin fever and head back outside with views of the Potomac. This is a 3 to 4 mile loop hike along the Potomac River just below the American Legion bridge off the GW parkway. The trail is mostly easy and flat, but there are some slightly rocky areas. Be aware that this time of year where segments along the river can be muddy and there are some rocky areas we must maneuver around. Bring a mascot! The park is dog-friendly, but must be on a leash. For more info and maps (see side links): [https://www.nps.gov/gwmp/planyourvisit/turkeyrun.htm](https://www.nps.gov/gwmp/planyourvisit/turkeyrun.htm) What to Bring: Good hiking shoes Water Meet: 9:00 am Where: Parking Lot C-1. (First parking lot when entering park. See map at link below for details) Park Trail Map: [https://www.nps.gov/gwmp/planyourvisit/upload/Corrected-Turkey_Run_Park_Trail_Map_11242023_508c.pdf](https://www.nps.gov/gwmp/planyourvisit/upload/Corrected-Turkey_Run_Park_Trail_Map_11242023_508c.pdf) Departure: 9:10 sharp. We should return to the parking lot no later than 11:15 am. For those interested, we can later head over to nearby Pho 75 (1721 Wilson Blvd) for a great hot pho - one of the best in the area. **Note: Cash Only!** **In the comments section please indicate if you need a ride. If you are coming by car and wouldn’t mind picking someone up at a convenient metro stop, please indicate how many people you can take. Hopefully we’ll have enough room for everyone. I can pick up three at the Braddock Road metro (yellow), located in Alexandria, VA. Or, I can pick up folks at Rosslyn metro (orange/blue). Carpoolers, please chip in generously for gas.** Note: This event is cross-posted with other Meetup groups.

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.

A Starfinder Society Scenario designed for 3rd- through 4th-level characters, playable in 2-3 hours. Kor-Montak is an ancient ritual site where shobhads of old communed with the spirits of the planet Akiton itself. A place of power and pilgrimage, Kor-Montak was abandoned sometime during the Gap and is believed to be cursed. In the ensuing centuries, numerous mystics, leaders, and warriors attempted the pilgrimage up the glacier passes to Kor-Montak, but none returned and Kor-Montak remains a place of myth and memory, lost to time but never forgotten. Impressed by the Starfinder Society’s dedication and ingenuity on a recent joint rescue mission, shobhad geomancer Aruk has invited the Starfinders to explore Kor-Montak and determine the cause of its long-standing curse. Aruk is hopeful the Starfinders can break the curse and return Kor-Montak to its people, as the Starfinder Society is known the galaxy over for their expertise in excavating ancient ruins and handling strange magic. Will you survive the ruins of the world soul? This is an adventure in the ongoing Invasion's Edge metaplot. Written by David N. Ross.

Many popular movies about flying machines bear the title “Drones,” but this isn’t one of them. No, this is a little-known gem about love in the workplace possibly leading to the destruction of planet Earth. Witty writing, solid acting, and slick direction all work together in this movie like bees in a hive, which coincidentally is the point of the title. The cubicle-bound employees of a vast corporation attend to their various tasks, each contributing to the productivity of the whole. But wait – is one of these workers not like the others? And if so, what is this person’s true agenda? When the answers to these questions arrive, the story gets hilariously crazy. The R rating is earned strictly by occasional rude language in this dialogue-driven production, and bluntly your host thinks PG-13 would have been sufficient. ■ Title — *Drones* ■ Director — Amber Benson, Adam Busch ■ Cast — Angela Bettis, Jonathan M.

**Gold Mine and Great Falls Overlook. A Moderate 6.5 Mile Hike** This hike features the remnants of a quirky gold mine and the classic overlook of Great Falls. The mine was established by a Union soldier who was stationed along the Maryland side of the Potomac River near Great Falls during the Civil War. He noticed a glint of gold and after the war, he returned to the area, bought some farmland, and started mining for gold. Eventually, 30 small mines were opened by various prospectors. One of the largest mines was the Maryland Mine. A total of 5,000 ounces of gold were produced by the mines in the area, worth about $10,000,000 in today's money. Today, little remain of these mines, but there is a loop trail that passes by one of them. The hike starts near Old Angler’s Inn, passes by the mine remains, then goes down to the classic overlook of Great Falls before returning to the woods and hiking back on trails with splendid views of the Potomac River. Bring a snack or lunch to enjoy at one of the overlooks, **Please note**: You must sign up by 5:00 PM the evening before the hike. **Time to Meet**: Please meet at 9:45 for introductions and sign in.

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.
