We’re so grateful for the early enthusiasm, and we look forward to seeing you each month as this community grows! **Date, Time & Location** 5:30 PM – 7:30 PM Tuesday 14 April 2026 Upside on Moore 1831 Moore Street Arlington, VA 22209

**Agenda :** * 4.45 to 5.00 PM ET: Food and Networking * 5.00 to 5.50 PM ET: "Hands-On : GitHub Copilot SpecKit" Hello Everyone! Please join us for our April 14th edition of the AI-ML MeetUp. **Please note this is an in-person meeting and light refreshments/food will be provided. You will need a government-issued ID to enter the facility.** **Title:** Hands-On : GitHub Copilot SpecKit **Description:** Spec-Driven Development **flips the script** on traditional software development. For decades, code has been king — specifications were just scaffolding we built and discarded once the "real work" of coding began. Spec-Driven Development changes this: **specifications become executable**, directly generating working implementations rather than just guiding them. In this hands-on lab, we will be covering building your application using SpecKit. Pre-requisites: VSCode v1.107, GitHub Copilot, Python 3.13 + uv, Git installed. **Location:** The meeting will be hosted in the Applied Information Sciences ( AIS ) office in Reston, at 11440 Commerce Park Dr # 600 · Reston, VA. The location is also right off the Silver Line metro's Wiehle-Reston Metro Station. **Parking:** Parking is paid and can be validated at the AIS office reception. We will meet in Room Lake Anne. We hope to see you all there!!!!

**​​​​​​​​A free, public workshop—no technical background needed** ​​​​​​​​ In just the past 8 months, AI has advanced at a pace that stunned even leading experts. These systems aren’t science fiction anymore—they’re reshaping work, relationships, and even crime in real time. ​​​​​​​​This workshop explores where AI may be in the next 1–5 years and what that means for your daily life. Together, we’ll tackle urgent questions like: * ​​​​​​​​**Jobs**: Could AI lead to mass unemployment—or entirely new kinds of work? * ​​​​​​​​**Crime**: How might AI supercharge scams, hacking, and even physical crime? * ​​​​​​​​**Companions**: Will people form deep emotional bonds—or even romantic relationships—with AI assistants? * ​​​​​​​​**Society**: How do top researchers think these trends will shape our future? **​​​​​​​​What you’ll get:** * ​​​​​​​​A fast-paced, beginner-friendly overview of today’s most powerful AI systems * ​​​​​​​​Live demos that reveal both the breakthroughs and the risks * ​​​​​​​​An interactive forecasting exercise where you’ll test your own predictions about AI’s impact ​​​​​​​​Come ready to explore a future arriving faster than most people realize—one that could transform not just how we work, but how we trust, connect, and even love.

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Goddess of Spring and the Underworld,”** an introduction to the Greek goddess Persephone in her many incarnations, with Brittany Warman, former instructor at Ohio State University and co-founder of the Carterhaugh School of Folklore and the Fantastic. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/spring-and-underworld](https://events.ticketleap.com/tickets/profsandpints/spring-and-underworld) .] Join Brittany Warman, who has earned a huge following among Profs and Pints fans by delivering fantastic talks on folklore, myths, legends, and fantasy, for the perfect event for the season: a look at the spring goddess Persephone and the many ways in which she has inspired the human imagination. The story of Hades and Persephone is one of the most famous—and most retold—episodes in Greek mythology. Persephone’s abduction, her interlude in the Underworld, and her partial return to the world above have inspired statues and webcomics, ancient cults and contemporary poetry. Thousands of years after her tale was first told, we’re still fascinated by this goddess. Brittany will discuss how Persephone’s appeal lies in her liminality in being caught between two very different worlds and lives. She represents spring, renewal, and rebirth because Earth blooms with her return, but she’s also the Queen of the Underworld. From a 21st-century perspective, she’s basically a goth girl adorned with a flower crown. We’ll also look at Persephone’s mythic roots, including their connections to the Eleusinian Mysteries. And then we’ll dive into some of the ways that Persephone has been revised and retold in recent years, from the Tony award-winning musical *Hadestown* to the webcomic *Lore Olympus* to memes and fairy tales and fashion. After all, why be just one thing when you can be the queen of both spring and darkness? (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

Title: Potential Applications of Negative Radiation Pressure in Astronomy, Medicine and 2WQC Date: April 19 2026 10:00 am - Noon EDT (16:00 - 18:00 CET) Abstract: While we are used to heating and pushing with light, there is also optical cooling and pulling. I will talk about negative radiation pressure, potential ways to generate it, and its novel applications, like non-ionizing medical scanners, 2WQC (two-way quantum computers) in theory solving NP problems, also potential astronomical sources and their observation. Speaker: Dr Jarek Duda is an assistant professor at Jagiellonian University. He holds degrees in computer science (PhD), mathematics (MSc) and physics (PhD). He is mainly focused on physics foundations, information theory, statistical analysis, and is known for introduction of asymmetric numeral systems.

Title: Foundations of Localized Symmetry Mathematics Date: April 18 2026 Noon - 14:00 EST Summary: The moment you use Euclid’s definitions of points and distances in any of your mathematical axioms, all that follows is assured to produce some level of nonsensical results when applied to the foundations of physics. The reason is not complicated: Euclid’s definitions are deeply mired in accepting as a “given” the very concepts that emerge only in well-defined inertial frames, which in turn are local instances of symmetries that are always finite and context dependent. In this talk, Terry will discuss how reframing mathematics in terms of symmetries that, as in the real world, are finite, composite, and dependent on self-observation (acceleration), results in a richer and far stranger set of mathematics in absolute conservation of quantum numbers generate local and global symmetries — the opposite of Noether’s theorem — that in turn create the emergent classical phenomenal such a particles, fields, space, and time. Speaker: Terry Bollinger is a computer scientist with BS, MS, and professional degrees from the Missouri University of Science and Technology.

​This meetup is for anyone building with OpenClaw (& Claude Code) or experimenting with other AI tools to create agents that can act and make decisions on their own. If you haven’t tried these yet, come hang out, ask questions, and see what others are building. We’ll trade notes, troubleshoot setups, and explore what it takes to run these systems openly on the web instead of inside closed platforms. Bring your laptop, grab some power, and jump into a night that feels part LAN party, part live build session, where people test ideas and show what their agents can actually do. 👉 [RSVP on LUMA](https://luma.com/53dx7no1) We’ll also have some fun by running a live test to see if a few of our agents can send Bitcoin back and forth and talk about why that’s a meaningful step for autonomous AI. It’s a chance to connect the dots between open AI tools, Bitcoin, and the wider goal of creating technology that no one can turn off. 👉 [RSVP on LUMA](https://luma.com/53dx7no1)

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus. Sponsored by [Transform Labs](https://www.transformlabs.com/services) Sign up also accessible via [Transform Labs Luma](https://luma.com/55umjqta)

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
