[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“The Secrets of Runes,”** on the origins, development, and interpretation of the runic script, with Lilla Kopár, runologist and a professor of medieval literature and culture at Catholic University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-runes](https://events.ticketleap.com/tickets/profsandpints/dc-runes) .] The fame of runes outshines that of any other ancient script. They can be found not just on Viking Age rune stones, but on Bilbo’s door and as the Bluetooth logo on your cell phone. Runic script is commonly associated with magic, used by modern practitioners of neopaganism, and in recent decades has captured the imagination of filmmakers and video game designers. Yet most of us know little about the historical origins of runes and have no clue how to read or use them. Come to Penn Social to get schooled on runic script with the help of Lilla Kopár, a veteran scholar of runes who has earned a following among Profs and Pints fans by giving fantastic talks on medieval monsters and Norse mythology. As someone who has carried out extensive field research on runes, published several articles on runic objects, and even appeared on the History Channel commenting on runes in America, she’s exceptionally qualified to introduce you to runology and the fascinating things that runes tell us. Dr Kopár will discuss the development of runic script from its humble origins on the borders of the Roman Empire in the first or second century CE, through its popularity in the Viking world, to its use and misuse in modern times. She’ll discuss how runes are a set of related alphabets that underwent changes over time and she’ll describe what inspired changes in this writing system and where and how runes were used in the medieval period. Her richly illustrated talk will highlight some of the most intriguing objects with runic inscriptions, from humble bone fragments to impressive rune stones, and offer insight into the scholarly methods of deciphering and interpreting runic inscriptions. We’ll also look at the function of the runic script from simple practical notes and memorial inscriptions to cipher-runes and magic. The most fun might be the in-class assignment, which will involve reading a few runic inscriptions and writing your name and other words in runes. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

While we do aim to play seriously and challenge ourselves, the focus is more on growth and enjoyment than simply winning at all costs. That’s why the title doesn’t include “competitive” or “social”—we want a healthy mix of both. We do expect a mindset geared toward learning and getting better over time. That said, this event isn’t intended for total beginners; an understanding of the game is expected so that everyone can contribute to meaningful and engaging matches. The host holds the right to remove you from the game if they believe that you are at a C level(absolute beginner). if you can't pass to the setter for example, you are a beginner. **Skill Level:** 1. **If you want to know your level, please see the link below:** [Smiley Social Volleyball Levels](https://docs.google.com/document/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/edit) **YouTube:** The games may be recorded and uploaded to our channel here: Let the host know if you have an issue with this.

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 Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. We will be hearing from Becca Powell, Director of Advocacy and Outreach at Unchained At Last, an organization whose mission is dedication to ending forced and child marriage in the United States through direct services and systems change. Unchained At Last's mission clearly meshes and addresses several of our Humanist Ten Commitments. Becca will educate us about an issue many of us may not be familiar with--but should be. 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.

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.

The market changed—and most investors are still operating like it didn't. Deals that used to work don't. Buyers want different things. And a lot of what's being taught right now is outdated or just wrong. And, since 2011, it's been our job to make sure that our members are armed with the most up-to-date, real-world strategies for building wealth in Central Ohio real estate… …so our mission with this meeting (and every meeting) is to give you the no-hype, warts-and-all info you need to succeed. First, Wholesaling 101—a clear, real-world look at how wholesaling actually works today, what to pay, and how to stay out of trouble. Then, Creative Deal Autopsies—real investors breaking down real deals with real numbers, real conversations, and real outcomes. You'll also get the chance to put the presenters in the hot seat and ask any and every question you have about how they did their deals. You'll learn: 1. What wholesaling actually is 2. How to calculate real offers 3. Where deals are coming from now 4. What buyers want 5. How creative deals are structured 6. What contracts and terms are used 7. What can go wrong—and how to avoid it **Agenda:** 5:00–6:00: Free Light Dinner and Networking 6:00: Earlybird Meeting – Wholesaling 101 7:00: Buy-Sell-Trade (members only) 7:30: Creative Deal Autopsies Members: Free First-time guests: Free Non-members: $35 (or join for $30 instead) Remember, to actually reserve your seat, you have to go **[HERE](https://www.coreerocks.com/Events.aspx?ID=IN-PERSON-in-Columbus-Creative-Deal-Autopsies-Wholesaling-101-14-4-7-2026)** and register on our website!
