Fabrication

***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! 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 4). To Join Virtually: https://meet.jit.si/mocomakers

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“The Single Lesson,”** a debunking of myths and misconceptions about singlehood and a look at research and advocacy efforts focused on the unmarried, with Craig Wynne, a professor of English at the University of the District of Columbia and pioneer in the growing field of Singles Studies. [Advance tickets: $13.50 plus sales tax and processing fees. Available at[ https://www.ticketleap.events/tickets/profsandpints/dc-the-single-lesson]( https://www.ticketleap.events/tickets/profsandpints/dc-the-single-lesson) .] All around us are messages that being “coupled up” is the norm. Shows like *The Bachelor*, 90-Day Fiancé, and *Indian Matchmaking* have people rooting and fawning for marriage. Yet, despite its supposed unpopularity, the rate of singlehood is increasing. By 2030, the Pew Research Center has projected, 25 percent of 45- to 54-year-old adults in the United States will never have married. What’s the real picture when it comes to singles? Is a growing share of the population missing out on marital bliss, or are single people on to something? Hear such questions tackled by Professor Craig Wynne, co-editor of *Singular Selves: An Introduction to Singles Studies* and author of *How to be a Happy Bachelor.* Dr. Wynne will discuss how stereotypes of singlehood are perpetuated in the media and how they influence laws, policies, and our daily social interactions in ways that harm not just single people but those who are married, cohabitating, or in a relationship. His talk will explore the concepts of “singlism,” the stereotyping and stigma around people who are not married or otherwise unpartnered; “matrimania,” over-the-top societal obsession with marriage and weddings; and “amatonormativity,” the assumption that a romantic relationship must be prioritized above all other kinds. Finally, Dr. Wynne will discuss the emergence of Singles Studies—a field devoted to granting singlehood validity in an academic context—and look at recent advocacy intended to secure single people equity in a world that still privileges being married or coupled.

Note: RSVPs for this meetup open when our last meetup ends. For February, we are reading Theft by Abdulrazak Gurnah. The book was first published in 2025 and the hardcover version runs 296 pages. The GoodReads blurb is In his first new novel since winning the 2021 Nobel Prize, a master storyteller captures a time of dizzying global change. At the turn of the twenty-first century, three young people come of age in Tanzania. Karim returns to his sleepy hometown after university with new swagger and ambition. Fauzia glimpses in him a chance at escape from a smothering upbringing. The two of them offer a haven to Badar, a poor boy still unsure if the future holds anything for him at all. As tourism, technology, and unexpected opportunities and perils reach their quiet corner of the world, bringing, each arrives at a different understanding of what it means to take your fate into your own hands.

As always, the goal is fun. Beginners are welcome. We play until 5 or 6. Parking (Free): Plenty of free street parking available on Sunday afternoons near the playing area. Contact Organizer for exact address and other helpful details Metro: Foggy Bottom Metro Station is an 8 minute walk

**Masterpieces in Real Life – DC Art Brunch Series** Inspired by this [Deconstructing.AI article](https://deconstructing.ai/blog-1/f/where-america-keeps-its-masterpieces), this series visits the most important artworks and objects in Washington in small, relaxed Sunday outings. We’ll look closely at 2–3 works, share the human stories behind them, and then continue the conversation over brunch nearby. Not a formal tour—just curious people learning to see together. I'll share a little background on the art and venue pairing for each outing. SCHEDULE & PAIRINGS **1) Leonardo & Vermeer – The Quiet Room** **Sunday, 12:30–3:30** **Art:** • Leonardo – *Ginevra de’ Benci* • Vermeer – *Woman Holding a Balance* • Bonus: Monet *Japanese Footbridge* **Meet:** National Gallery West Building, Constitution Ave entrance **Brunch after (3 min walk):** **The Smith – Penn Quarter** – bright, easy tables, good for groups **Masterpieces in Real Life #1 – Leonardo & Vermeer** We’ll begin where Washington quietly keeps two of the most intimate paintings in the world. Leonardo da Vinci’s *Ginevra de’ Benci* is the only Leonardo in the Americas, yet it behaves nothing like a celebrity. The panel is small, moody, and slightly wounded—its lower edge trimmed centuries ago, taking Ginevra’s hands with it. What remains is a face suspended between confidence and doubt, framed by juniper leaves that pun on her name. Nearby, Vermeer’s *Woman Holding a Balance* performs a different kind of magic: a domestic scene so still you can almost hear the dust settling. The scales may hold pearls or nothing at all; scholars still argue, which is part of the pleasure. The National Gallery’s West Building is the perfect stage for this slow kind of looking—marble floors that encourage quiet footsteps and skylit rooms that make even hurried visitors lower their voices. We’ll wander from Leonardo to Vermeer and then to Monet’s luminous bridge, tracing how artists turned light into a language. No lectures, no exams—just stories about missing hands, hidden pigments, and the surprising ways these works ended up in Washington instead of Florence or Delft. After the gallery, we’ll walk a few minutes to **The Smith** in Penn Quarter, a bright brasserie that feels like the cheerful cousin of the museum: high ceilings, good bread, and tables made for lingering conversations. Over brunch we’ll compare first impressions—Did Vermeer feel calm or unsettling? Is Leonardo’s Ginevra shy or simply unimpressed with us?—and let the art continue to do what it does best: start arguments among friends. *** \*\*\*\*\* Coming Up Next\*\*\*\*\*\*\*\* ### 2) Van Gogh / Degas / Rodin – Bodies & Minds **Sunday, 12:30–3:30** **Art:** • Van Gogh *Self-Portrait* • Degas *Little Dancer* • Rodin *The Thinker* **Lunch (4 min walk):** **Oyamel** – lively but not loud, great sharing plates *** ### 3) America in Objects **Sunday, 12:00–3:00** **Art & Objects:** • Star-Spangled Banner • Greensboro Lunch Counter • Julia Child’s Kitchen • Ruby Slippers **Lunch (2 min walk):** **Carmine’s Penn Quarter** – easy large tables *** ### 4) Flight & Moon – Fragile Futures **Sunday, 12:30–3:00** **Art/Engineering:** • Apollo 11 Columbia • Wright Flyer **Lunch (5 min walk):** **Cafe Riggs** – calm, elegant, conversation-friendly *** ### 5) Memory in Stone – Evening Light Edition **Sunday, 1:00–3:30** **Art:** • Lincoln Memorial • Vietnam Memorial **Lunch (before walk – 12:00):** **Tonic at Quigley’s** – reliable, close to Mall *** ### 6) The Hope Diamond & the Stories We Invent **Sunday, 12:30–3:00** **Art:** • Hope Diamond • Geology hall **Lunch (5 min walk):** **Old Ebbitt Grill** – classic DC, easy meet point *** ## FLOW OF EACH EVENT **12:30** – Meet outside museum **12:35–2:00** – Slow look at 2–3 works **2:00** – Walk together to lunch **2:10–3:30** – Brunch/lunch + conversation

Dale Gnidovec, Curator of the Orton Hall Museum of Geology at The Ohio State University, will be presenting a program he has wanted to share with us for a long time: Plate Tectonics. His description of his program: Continents on the move - Nothing in Earth history makes sense without moving continents - it tells us why mountains, volcanoes, minerals, and fossils are where they are. This talk examines the evidence for continental drift, why it was disbelieved, and explains how the more-encompassing theory of plate tectonics was developed and eventually proven. Dale is an energetic, incredibly knowledgeable, and very entertaining speaker and this will be another wonderful program by Dale. Hope to see you there! Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid.

I love my job and one of the main things I do is help customers get going with any of the data technologies at Microsoft. Right now there are a lot of my customers asking about Microsoft Fabric. It's hard to weave across all the shiny new options across the Fabric landscape, let alone figure out where it fits into your organization. In this session we'll focus on answering one question - how can I get data into Fabric? We'll talk through the "it depends" options and see some of the options in live demos.

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
