The Power of a Peaceful Mind
The Power of a Peaceful Mind
The Power of a Peaceful Mind In situations of conflict, we easily become angry. However, anger limits us and leaves a trail of painful feelings. On the other hand, the creative mind of patience opens us to options. In this series, we learn to understand and meditate on patience. We will discover how meditation helps us to find peaceful solutions to everyday problems. **REGISTRATION** Standard: $12 \| Financial Hardship: $6 \| Free for [Members](https://meditation-dc.org/membership/) [Pre-Register Here](https://meditation-dc.org/monday-evening-meditation/) Each class is available by drop in.

Profs & Pints DC: The Secrets of Runes
Profs & Pints DC: The Secrets of Runes
[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.)

Read & Reflect: A Social Reading Circle. Shared Pages, Shared Insights.
📚 Do you love reading, but wish you had a structure and a community to share your insights with? Join our small circle of curious minds (just 4 members per gathering) as we come together for an hour of focused reading—in the calm setting of a library or the cozy atmosphere of a café. Here’s how it works: First part: Quiet reading on your own—bring a book you’re exploring, whether it’s philosophy, history, psychology, literature, or anything meaningful to you. Second part: We regroup and each person shares key takeaways, insights, or questions sparked by their reading. This sparks a structured yet free-flowing conversation around ideas, perspectives, and personal reflections. Why join? Add structure to your reading habit. Discover new books, authors, and ideas through others’ choices. Build real connections by sharing and listening deeply. Socialize around something meaningful instead of small talk.

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.

On Monday, we'll meet in front of 2100 Clarendon Blvd (https://maps.google.com/maps?q=2100+Clarendon+Blvd&ll=38.889847,-77.084005&spn=0.009704,0.017531&hnear=2100+Clarendon+Blvd,+Arlington,+Virginia+22201&gl=us&t=m&z=16&layer=c&cbll=38.890666,-77.085485&panoid=Vy-Mbkk_fU1USwuw4_R6SQ&cbp=12,140.28,,0,0) around 6:50pm and head out for a nice hilly run at 7pm. We usually head out for a drink after the run. So if you're planning to stay after for drinks, bring your ID/etc. Notes: If you're not familiar with the area, please review the routes. If it's cold, take cover inside the foyer area of 2100 Clarendon Blvd. Photos taken during the event may end up on Instagram, Meetup, Strava and similar platforms. Routes: We'll alternate between the following routes. Both routes are hilly. We'll run 20 minutes out and then turn around and run 20 minutes back to Courthouse. Everyone runs at his/her own pace, so the distance will depend on your speed. 1. Courthouse to Georgetown Waterfront (one giant hill) (https://www.mapmyrun.com/routes/view/6264227038/) Veitch St. to the Custis Trail; downhill to Key Bridge; over to the Georgetown Waterfront. 2. Courthouse to Custis Trail West (rolling hills) (https://www.mapmyrun.com/routes/view/6600124130) Veitch St. to the Custis Trail; West toward Glebe Rd. Pace: All paces are welcome! We'll be doing an out and back route, so everyone will just turn around at the halfway time marker. That way we should all start and end at the same time. Free Parking at Courthouse Plaza: The underground garage (http://tiny.cc/OmKZx) is on Clarendon Blvd btwn Wayne and Veitch Sts. (near Strayer/CVS and the AMC Theater). If the first 2 levels on the left are full, you can park on the lower levels to the right. Street and Surface Parking lots should be free in the area as well.

CBusData: The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
CBusData: The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
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.

In-Person Event: The Answers to Depression & Anxiety
In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them. Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance". Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. 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. 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 Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
