***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.

This is a VIRTUAL FREE event every week. To get access details please [click here](https://www.eventbrite.com/e/the-recharge-fill-up-sis-tickets-1984961497272?aff=oddtdtcreator) If you’ve been pouring into everyone else and quietly running on empty… this space was created for you. There comes a moment in a woman’s life when she realizes she has been pouring into everyone and everything else… while quietly running on empty. The responsibilities. The expectations. The emotional labor. And somewhere in the middle of holding it all together, she forgets what it feels like to be **fully supported, fully resourced, and fully seen**. **The Recharge: Fill Up Sis** is **a sacred weekly virtual meetup** created for women who are ready to pause, recalibrate their energy, and reconnect with themselves in powerful community. This is not a motivational talk. This is not surface-level inspiration. This is a room where women gather to **release what they’ve been carrying, restore their energy, and remember the power of being in [intentional sisterhood](https://thewombsauna.com/wcoe "https://thewombsauna.com/wcoe").** ## What Happens in The Recharge? Each session is a guided experience where women come together to: * **Release** stress, emotional weight, and the pressure of carrying everything alone * **Restore** their energy through meaningful conversation, reflection, and grounding practices * **Rise** into clarity about what their next level of life and leadership requires * **Radiate** with renewed confidence, alignment, and direction This space allows you to experience the tone, leadership, and sisterhood that define the deeper work we do together. ## The Integration Lab: Where Knowledge Becomes Embodiment Many women spend years gathering wisdom. Books. Podcasts. Workshops. Spiritual insight. Therapy. Coaching. At a certain point, the question is no longer: **“What else do I need to learn?”** The real question becomes: **“Where am I actually practicing the life I say I want?”** The **Integration Lab** is the weekly coaching and practice space inside our **[1-Year Self Development Program](thewombsauna.com/programs)**. It is where women stop circulating knowledge and begin **embodying it**. Inside the Lab, we work in real time with the patterns, decisions, emotions, and relationships shaping your life right now. Awareness becomes action. Insight becomes discipline. And personal growth becomes a lived lifestyle. Women gather weekly to: * apply what they know to real-life challenges * strengthen emotional regulation and self-leadership * practice accountability in sacred sisterhood * build the consistency required to live differently This is not a space for passive listening. It is a space for **active personal development and sacred community life.** ## Who This Space Is For? This gathering is for women who: * are tired of carrying everything alone * know they are capable of more but feel stretched thin * value personal development and emotional growth * desire a circle of women who are serious about their evolution * are exploring whether they are ready to invest in a **year of intentional growth** Many women who attend **The Recharge** are preparing themselves to decide whether they are ready to step into the deeper commitment of the **[1-Year Self Development Program](https://thewombsauna.com/programs "https://thewombsauna.com/programs")**. ## What You Should Know This experience is **free**, but it is intentional. Women who attend are often exploring what it would look like to: * prioritize their personal development * practice emotional and spiritual growth consistently * participate in a high-level community of women committed to living consciously Come with curiosity. Come with honesty. Come with the willingness to pour back into yourself. ## Hosted By ## **[Thema Azize Serwa](https://thewombsauna.com/thema "https://thewombsauna.com/thema")** Founder of **[The Womb Sauna](https://thewombsauna.com/ "https://thewombsauna.com")** and creator of transformational spaces where women gather to **release, restore, rise, and radiate**. After overcoming eight years of infertility and PCOS, Thema devoted her life to helping women reconnect with their bodies, their emotional wisdom, and the sacred power of intentional community. Through her work in womb wellness, self-development, and spiritual leadership, she has guided women around the world in creating lives that are rooted in clarity, healing, and self-mastery. ## Final Invitation If you’ve been gathering insight for years but feel ready to start **living differently**, this space will resonate deeply. Because transformation does not happen through inspiration alone. It happens through **consistent practice, honest reflection, and community that supports your evolution.** **Come recharge.**

**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.
