***Meet us in the Rockville Library, Collaboration room #4 where we will attempt to run clean scans of gold samples, and then clean up that data with post processing.*** This is a high sensitivity experiment, and we do not plan on being successful so early. But we've had promising results lately - so we will be putting in the time. Online join link is: - [https://meet.jit.si/mocomakers](https://meet.jit.si/mocomakers) 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. 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 will be publishing our work here -[ https://hackaday.io/project/202816-qt-panda](https://hackaday.io/project/202816-qt-panda) Meet us in the Rockville Library, Collaboration room #4

**AI-Supported Creative Exploration** *For Unassuming Intuitives & Practicing Creatives* (Please note that this event has not been organized or endorsed by The Writer's Center.) This meetup is part of AI as Creative Partner — A Practice Group, a set of open, non-sequential creative labs you can join at any point. We use AI as a thinking partner—not to replace your ideas, but to help surface and shape them without overthinking or pressure. You bring fragments—ideas, impulses, unfinished concepts. With AI as a supportive collaborator, we explore how those fragments can become clearer, more coherent, and ready to share if and when you want to. No technical background is required. If you can talk or type, that's enough to work with AI here. This session is intentionally low-commitment and flexible: * Arrive late or leave early * Work quietly or observe * Ask questions, or simply watch the process unfold There's no presentation and no expectation to finish anything. Showing up as you are is enough. **CREATIVE WORK, GENTLY - AN OPEN PRACTICE NIGHT** This is not a workshop or a class. It's a calm room where people show up to work creatively—without urgency, performance, or pressure—using AI as a thinking partner. Come for 20 minutes or stay the whole time. Work quietly, observe, or ask questions. This space adapts to how you arrive. **HOW TO FIND US** Look for the room with the door open on the lower level. Look for the guy with the screen projector and ambient light and sound. Feel free to just walk in and settle. **(*This is an independent meetup using rental space at The Writer's Center. The Writer's Center has not organized or endorsed this event.*)**

Title: Beyond Cryptography: Geometric Symmetry & Parity Stability Summary: Decoding Chaos: Using Quantum-Inspired Symmetry Metrics to Detect Stealth Attacks in High-Stakes Infrastructure. Agenda: Why symmetry matters after the proof is done. Symmetry as an Invariant Symmetry as a Security Primitive Trust as a Continuous Function Live Thought Experiment Engineering, Implications & Open Questions Move away from traditional bit-matching and discuss "Symmetry Drift." Explain how system states can be modeled as high-dimensional manifolds where an attack represents a geometric deformation.T(t)=f(symmetry stability,parity consistency,temporal coherence) Speaker: Vijay Krishna Vijay is a security engineer focused on runtime observability and symmetry drift in cryptographic systems. He is the founder of Vyapti Resonance and the creator of the Quantum Security Probe (QSP), a telemetry-driven integrity monitoring framework for post-quantum infrastructures. His work bridges theory, engineering, and long-lived system behavior, emphasizing measurable trust over binary verification. Vijay has 9 accredited licenses in Quantum Computing. Career Snapshot: Microsoft → DuPont → Rockefeller Capital Management → Morgan Stanley → New York Life → Founder, Vyapti Resonance Across this trajectory, Vijay has operated at the core infrastructure layer of organizations—cloud platforms, identity systems, distributed compute, reliability engineering, and governance frameworks. His work has consistently involved systems that cannot fail, particularly in regulated financial and insurance environments. This enterprise grounding strongly informs his academic and research outlook: quantum and AI systems must be operable, governable, auditable, and teachable, not merely theoretically elegant.

**Join us in Falls Church for conversations that go beyond small talk.** Higher Grounds – Falls Church is where this growing network of gatherings began: a space for thoughtful, authentic dialogue about what matters most. Whether we’re exploring the nature of happiness, the challenges and possibilities of midlife, spirituality, culture, capitalism, parenting, or the role of art and travel in a meaningful life, every conversation is shaped by the people in the room. There’s no set leader or rigid agenda—just a shared commitment to listen as much as we speak. We start with brief introductions focused on what makes you *you* (not your LinkedIn bio), then dive straight into whatever is on people’s minds. The direction of each meetup emerges organically, making every event unique. MANDATORY: PLEASE REVIEW OUR COMMUNITY GUIDELINES IN THE GROUP DESCRIPTION. Everyone is expected to engage in respectful conversations and listen deeply as well as share. We have a zero tolerance policy of sexual harassment and hate speech. Come ready to share, reflect, and connect with others in Falls Church who are also seeking deeper conversations. **Suggested Questions: Life Stages & Transitions** 1.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.
