[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.)

**\* This is an in-person event** Most people only experience finished products. Very few get the opportunity to work on something before it's finished when it can still be shaped. This is one of those opportunities. Karen Hold, Director of DT:DC, is currently developing a new innovation skills workbook with Jeanne Liedtka, based on over a decade of teaching and working with leaders across organizations, universities, and the DT:DC community. Her work focuses on the five statistically validated skills that help people develop as innovation leaders. This workbook builds on her work in design thinking and innovation education, including programs at the University of Virginia Darden School of Business, École des Ponts Business School (Paris and Casablanca), and Boston College. For this session, Karen will share a draft chapter of her new workbook for live testing. This is not a polished workshop. It's a working lab. You won't just participate. You will help shape the material itself. What We’ll Be Testing: * Whether the exercises actually help people think differently * Where the material is clear and where it breaks * What feels useful vs. what needs to be reworked This is the kind of work that typically happens behind closed doors. **What You'll Do** Working in small groups, you will: * Work through exercises from a draft chapter of the workbook * Apply them to real situations and ideas * Share feedback on what is clear, confusing, or missing * Help identify how the material can be improved You’ll get: * Early access to work that is still being developed * A chance to influence how this material evolves * Practical tools you can immediately apply * A behind-the-scenes look at how skill-building experiences are designed This is a rare opportunity to be part of the process, not just the outcome. Join us if you want to be part of something early, unfinished and actively evolving. No prior experience is required. **About Karen Hold** Karen Hold is the founder of Experience Labs and Director of DT:DC, one of the world's largest innovation communities connecting founders, designers, policymakers, and changemakers. Her work sits at the intersection of teaching and real-world application. She works with Fortune 500 corporations, federal government agencies and non-profit organizations, helping teams strengthen how they think, make decisions, and move ideas forward. She teaches in graduate and executive education programs, including at the University of Virginia Darden School of Business, École des Ponts Business School (Paris and Casablanca), and Boston College. Karen is a co-author of *Experiencing Design – The Innovator’s Journey*, and her work focuses on developing the skills that enable individuals and organizations to navigate complexity and create meaningful change.

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. You can meet us in-person or attend online Join Zoom Meeting [https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1](https://us02web.zoom.us/j/87836564953?pwd=4Mi57ElZkDIFlb1fnlNwOJ0NiOK4tP.1) Meeting ID: 878 3656 4953 Passcode: 760812 One tap mobile +19292056099,,87836564953#,,,,\*760812# US (New York) +13017158592,,87836564953#,,,,\*760812# US (Washington DC) The formal presentation will start at noon

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.

This is a free, in person meeting. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.
