[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.)

Click here to attend: [https://www.jgoot.com/livestreams](https://www.jgoot.com/livestreams) Sometimes the difference between a decent booking and a great one isn’t more points, more time, or more effort. It’s one simple check. One small decision. One moment most people skip… and pay for later. It’s time for: **The Step Most Travelers Miss (And the 60 Second Solution to Never Miss It Again)** JGOOT Lounge Expert Coach Mira will be live with us to break down what that step is, why it matters more than most people think, and how it changes the way you approach every booking. This isn’t about chasing perfect redemptions. And it’s not about adding more complexity to your process. It’s about removing guesswork. Making faster, smarter decisions. And having confidence that you’re actually making the right call before you click “book.” Mira will walk through: • The step most travelers skip when evaluating a booking • Why “good” redemptions can still be the wrong choice • How to quickly compare your options without overthinking it • What to look for before you commit points or cash • A simple way to make sure you’re getting it right, every time This is the kind of session that makes everything else you’ve learned more effective. Because once you see it, you can’t unsee it. Whether you’ve been booking with points for years or you’re still figuring things out, this will give you a faster, clearer way to make decisions and avoid the mistakes most travelers don’t even realize they’re making. And once you have it, you’ll wonder how you ever booked without it. Click here to attend: [https://www.jgoot.com/livestreams](https://www.jgoot.com/livestreams)

***“I am struck with how rare it is to find a few good friends on the path. It is easy to find people who simply want to sit and be entertained by teachers, or who want to sit and entertain by playing the role of teacher. In other words, the quest for affirmation often outweighs the quest for truth.*** ***Yet you may have one or two good friends, and definitely have one or two waiting to be discovered. Find them; be thankful.”*** ***— Shawn Nevins*** 'What will make me happy in life?' ... 'Am I my thoughts?' ... 'What is Enlightenment?' ... We meet every week to ask questions like these in the pursuit of Self-Knowledge and Truth. We are interested in topics like: Zen, stoicism, spirituality, psychology, mindfulness, Nisargadatta, non-violent communication, Socrates, existential philosophy, Alan Watts, taoism, Eckhart Tolle, meditation, Ramana Maharshi, etc. But we are not affiliated with any dogma, philosophy, or religion. Our goal each meeting is to serve as mirrors for one another using question-based inquiry in a safe environment. In a session, every participant takes turns discussing the week's question or topic, and the group asks reflective questions without any agenda besides trying to understand the person's beliefs. A few other guiding principles of our group: * No one is obligated to share * Be honest with yourself and others * Do not try to convince others to believe or think as you do * Keep the focus on the person being questioned We meet at the [Bethesda Library](https://maps.app.goo.gl/GWMozF8zpY1m1PY26) every Monday. The library is a 5 minute walk from the Bethesda Metro on the Red Line, approx 25 minute Metro ride from Metro Center and Gallery Place stations. The library has a a parking lot with metered parking for $1/hour. \*\*\* WE WILL BE IN MEETING ROOM 3 UNLESS OTHERWISE NOTED ----- THE MEETING ROOM IS IN THE BACK OF THE LIBRARY \*\*\* Please contact us with any questions!

We will be hiking along the historic Alexandria waterfront down and through scenic Old Town to the Wilson bridge and back. Lovely views of the river, as well as of Old Town. Part of the walk is on the Mount Vernon Trail bike path. Hike is mostly flat, and on paved surfaces or board walk. Please note the hike leaves at 600PM sharp. There are bathrooms at the halfway point. **Meet at the small parking area closest to the bike path. First left on Marina Drive. Not the large marina parking area that is further along.** We walk pretty briskly around 3.-3.5 miles an hour. I assume if you can’t keep up, you can always find your way back to the starting point. Hope you can join our group of stalwart regulars and cheery newcomers. Happy hiking. Most of the walk has street lights, but not all so, but bring a light.

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.

It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself. Here is the secret of being positive and free: Thinking positively is not enough. You also have to get rid of the negative thinking. Your mind is like a garden. You can plant many beautiful flowers in it, but if you don't get rid of the weeds when you plant your flowers, the weeds will soon take over the whole garden. A positive thought is like a flower in your mental garden, and a negative thought is like a weed. You cannot expect to have a positive mindset if you continue to have negative thoughts dwelling and growing there. So, how do you get rid of the negative thoughts? That's what this Meetup is all about. Attend this local meeting and find out! The Meetup event will be led by a consultant who had helped many people live happier in life. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Dianetics & Scientology life improvement center.
