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.

The highlight of this route is the roll through East Potomac Park and 4 miles of thousands of blooming Yoshino 桜 cherry trees at peak blossom. Good format for beginners to street skating: not too many hills, and more good pavement than bad, 7 miles total. We will start at World War I Memorial, hit the 15th street bikeway, roll through the Moongate Garden, climb the stairs to take in the vista at L'Enfant, Hains Point cherry tree loop, regroup at the circle at Maryland Avenue Park. Then the skate ends at a tea house: Teaism! Dress in theme: blossoms or pink. Route: http://www.gmap-pedometer.com?r=7570647 We will reschedule if the ground is not dry. Inclusive event - Beginner pace and all skaters are welcome and encouraged to roll with us.

A beginner-friendly workshop on advanced AI, government policy, and how this new technology is evolving and impacting society. ​​​​**Free and open to the public — no technical background required** ​​​​In previous workshops, we've seen how AI is a transformative technology like no other, for better or for worse. Beyond the technology itself, however, government regulations and societal norms will inform the impact AI has on our world. ​In this workshop, we will explore what policies have been proposed, which have been implemented and why, and what the impact has been so far. How can we use these lessons to maximize the promise and minimize the peril of AI? ​​​​**Over the course of the workshop, we’ll explore:** * ​**Concepts and Goals:** What problems should AI policies be trying to solve? * ​​​​**Different Kinds of AI Policies:** What policies have been proposed so far? What are the pros and cons? * ​​​​**Political Landscape:** How are financial incentives and conflicting ideologies influencing AI policy? * ​​​​**Case Studies:** What can we learn from what's been passed so far? ​​​​**What you’ll get:** * ​​​​A clear, non-technical introduction to core ideas from AI safety, AI governance, and existential risk research. * ​​​​Small-group discussions and thought experiments that connect AI risks to everyday life, institutions, and incentives. * ​​​​A better mental model for evaluating headlines, hype, and claims about AI progress. ​​​​**Format & vibe:** ​​​​This is not a lecture it is an interactive workshop designed to help people think clearly about a topic that is increasingly important and moving very quickly. ​​​​Whether you’re new to AI, casually interested, or deeply unsure what to believe, you’ll leave with a clearer picture of *why* many researchers take AI seriously—and *what’s actually at stake* if we get it wrong.

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)

Let's bedazzle some books while we discuss our April pick: Bloodguard by Cecy Robson! Book description: One hundred years. Tens of thousands of gladiators. And today, only one will rise… Everything in the Kingdom of Arrow is a lie. Leith of Grey thought coming to this new land and volunteering to fight in the gladiator arena—vicious, bloodthirsty tournaments where only the strongest survive—would earn him enough gold to save his dying sister. He thought there was nothing left to lose. He was wrong—and they took everything. His hope. His freedom. His very humanity. All Leith has left is his battle-scarred body, fueled by rage and hardened from years of fighting for the right to live another day. Then Leith meets Maeve, an elven royal who is everything he despises. Everything he should hate. Until the alluring princess offers him the one thing he needs most: a chance to win the coveted title of Bloodguard—and his freedom. But in a kingdom built on secrets and lies, hope doesn’t come cheap. Nor will his ultimate revenge… Event: Please bring your own book, journal, bookmarks, etc to bedazzle. If you have bedazzling supplies, please bring them as well. I will supply gems, glue, and picker tools, but if you have certain colors in mind, you may want to bring your own.

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

**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
