***In Person Location:*** Rockville Library, second floor meeting room (Collaboration Room 4). 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! We've identified a flawed powerline component we, if it comes soon enough we will solder it in, and troubleshoot downstream electronics to see if any other components are busted (following a wiring mishap). We've had this component 'blow out' before and fixing it then we sufficient, so hopefully we get lucky again. The component however is currently very delayed, so until that comes we might need to focus on a backlog of documentation development. 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 4). To Join Virtually: https://meet.jit.si/mocomakers

Date : Dec 20 2025 13:00 - 15:00 EST Title: Why Classical Physics Could Not Unify Gravity: The Missing Density Constant Summary: Classical physics divides nature into two regimes: a quantum world governed by the Planck constant h, and a gravitational world governed by the Newtonian constant G. 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. Note: This is an online event. The Zoom registration form will be provided no later than one hour prior to the event start time.

To purchase tickets - https://www.annkite.com/friday-nights This is a group of up to 70 people that dance the 5Rhythms together weekly on Friday evenings. 5Rhythms® is a philosophy, perspective, performance art and a dynamic movement practice rooted in the principle that if you put the psyche in motion it will heal itself. Movement is both the medicine and the metaphor, reaching across all languages, cultures and age groups to transform suffering into art, art into awareness, and awareness into action. Wherever the 5Rhythms are practiced, a community is born to dance, to sweat, to change, to support, and to provide a safe space for each of us to shatter the ego’s hold and awaken the juicy, unpredictable, fascinating, edge-walking, rock star part of ourselves that yearns to be free. Creativity. Connection. Community. There are no steps to learn. 5Rhythms can be practiced by anyone regardless of age, fitness, ability, or experience. For more information about what to expect in your first 5Rhythms class, see our About 5Rhythms page: https://www.annkite.com/about

Hey Poetry Lovers! This group is on a roll. Here’s the gist: We meet at the **Capital One Café in Chinatown** from **12pm - 2pm** every other week. For enrichment, we start by reading and reflecting on a **“published poem”**, suggested by someone in the group. No advance preparation is necessary. But feel free to check out some of the poems we’ve read [here](https://docs.google.com/spreadsheets/d/e/2PACX-1vSyE_wCLQCPHRrKmN5F9tOIeeRQUZESxjRXGVBoCF2uU8Gm0_d0uECiCBCQXEy6ksxfsBOhtRIOpW3T/pubhtml?gid=0&single=true&widget=true&headers=false%22%3E%3C/iframe%3E). Or submit suggestions for future meetings [here](https://docs.google.com/forms/d/e/1FAIpQLSexGc2Z2Kp6bZW0D3_hfJ7NUUkfNHf7TXX-43FglCeBd9EF2Q/viewform?usp=send_form). Next, we **share our work and offer feedback**. Depending on attendance, everyone gets \~10 minutes to use as they like. (No need to share, though; you’re welcome to come even if you prefer just to listen.) We maintain a **Discord server** to help share our work and communicate outside our bi-weekly meet-ups. If you haven’t used Discord before, take a moment to download it and create an account before arriving. When we meet you on Saturday, we will add you to our server, the “DC Poetry Workshop”, and can help you navigate the app if you have questions. Finally, if you plan on sharing a poem, consider how you will do so. Some options include: * Print 5-10 copies to distribute in person * Take and share screenshots in the Discord chat. * Copy the poem into a google doc, change sharing settings to “anyone with link”, and copy the google doc link into the Discord chat. Most importantly, we’re excited to meet you! Catch you on Saturday, Diego / Ian / Cayden / Nate / Otasha / Lia / An

Mental Health, how do you understand it? How can you improve it? How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp. This group is hosted by the Dianetics and Scientology Life Improvement Center of Central Ohio.

Join us as we get the New Year started with one of the best films of the year: THE SECRET AGENT! This political thriller from Brazil is set in 1977 where a man flees from a mysterious past and returns to his hometown but soon finds the city is far from being the refuge he seeks. Here’s a description, trailer and plan for this event: DESCRIPTION: In 1977, a former professor flees from a mysterious past and returns to his hometown of Recife in search of peace. He soon realizes that the city is far from being the refuge he seeks. The film stars Wagner Moura, Carlos Francisco, Tânia Maria, Robério Diógenes, Maria Fernanda Cândido, Gabriel Leone and Udo Kier in his final film role. TRAILER: https://www.youtube.com/watch?v=9UfrzDKrhEc BUZZ & ACCLAIM: The Secret Agent was the most awarded film at the 2025 Cannes Film Festival where it won Best Actor for Wagner Moura, Best Director for Mendonça Filho, the Art House Cinema Award and the FIPRESCI Prize. At this year’s Golden Globes, it became Brazil’s first film ever to be nominated for Best Film (Drama)! It also received a Golden Globe nomination for Best Foreign Film, a Best Actor nomination for Wagner Moura and was selected as Brazil’s entry for Best International Film at this year’s Academy Awards. The film is receiving an incredible 99% positive rating on Rotten Tomatoes where critics say, its “compelling script, impeccable acting, and striking 1970s aesthetic” make it “impossible to look away!” Critics say The Secret Agent is “one of the few standout movies of the year” and the Chicago Tribune calls it a “masterpiece of a film” and “the best film of the year!” PARKING: Close, convenient parking is available in the nearby garage (located between 9th and 11th, just off High St). Bring your ticket with you and have it validated at the theater and for $2, you’re covered for the night! PLAN: We’ll plan for a 7pm-ish showing and will meet in the lobby area about 30 minutes before showtime! With this being a limited release film, we’ll tentatively plan to see it at the Gateway, but location may change based on where it is showing and the showtimes available. Once details are confirmed, advance ticket is advised. Once you have yours, please list your seat number in the Comments section of this event. Showtime, location and complete details will be confirmed and announced as the date gets closer. Happy New Year and look forward to seeing you there, Dan
