Join us for an exciting evening of Chinese Mahjong, where players of all skill levles are invited to come together for fun, laughter, and friendly competition! **Please bring $5 to play!** Whether you're a seasoned pro or a curious beginner, this event is designed to foster a welcoming atmosphere where everyone can learn, play and enjoy the timeless game of Mahjong. **Game plan** Each attendee needs to bring $5 cash to play. **$1 per game:** Each player will contribute a dollar for every game we play. Don't worry; the winner gets to keep their dollar! **$3 per game for Wright to Read:** The remaining $3 from each game will go into our collection jar. At the end of the year, we'll donate these funds to **Wright to Read** which has been providing services in the city of Alexandria for over 45 years. Wright to Read recruits, trains, and supports volunteer tutor-mentors who support elementary-aged children enrolled in ACPS who have been identified as needing additional support in reading. More info here: https://www.campagnacenter.org/program/wright-to-read/ We raised $535 in 2025 (Goal was $500) 2026 goal is $600 Let's make our mahjong nights not only fun, but also impactful! **Per usual book club nights,** **attendees are also asked to please bring one of the following:** 1. A wine or beverage of choice 2. A cheese & cracker or alternate nosh of choice Host will provide glasses, wine opener, plates & napkins. **What to Expect:** \- Friendly games with players of varying experience \- A brief introduction to the rules for beginners \- Opportunities to meet new people and connect with fellow enthusiasts \- Light snacks and refreshments to keep you energized Don't miss the chance to dive into the world of Mahjong. Bring your friends or come solo - everyone is welcome! We'll reconfirm RSVP's again before the event to avoid no-shows and allow those on the waitlist an opportunity to join. We look forward to a fantastic night filled with strategy, skill and socializing! **WAITLIST:** Meetup does not allow a waitlist for paid events. If this event fills and you are interested in adding your name to the waitlist, please send host a message through the app. \*\* The small non-refundable registration fee helps us share the cost associated with the Meet-Up platform ($360/yr) and reduces the likelihood of no-shows, allowing us to better plan our events and accommodate all participants. Meetup charges $0.51 and Paypal charges $0.53 on the $2 registration fee. Thanks in advance for your understanding!\*\*

Early riser? Need to get your run in before the kids are up and the busy-ness of the day sets in? Join other early morning runners at the CAVA in Bowie, 15480 Annapolis Rd. The group meets at 5:30am and promptly sets out for a 3-5 mile run along Annapolis Rd. It's best if you arrive a few minutes early. **\*\*This is a regularly scheduled run and Kim, the run-host, does not check RSVPs on meetup. New runners are encouraged to email membership@pgrc.org for more info, prior to coming out.**

Doubles Volleyball - Competitive BB-A level @Bluemont Park Let's get together to play some fun A level Doubles games at Bluemont. Format: Doubles COST: FREE Court Type: Outdoor grass Minimum Skill Requirements: BB-A level (click [here](https://docs.google.com/document/u/2/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/mobilebasic) for details) Attention: 1. This event is not always on a first come, first served basis. Those who can bring a net and ball, may get priority over others on the waitlist. 1. Since skill levels are self-reported, some attendees may not meet the expected level in reality, so we encourage you to choose a partner you can enjoy the game with, and since this is a competitive event, it is okay if you make a strong team and win all the games. 1. Since people arrive at different times, each group of 1. Players will set up and claim a net as they arrive, and may continue playing without rotating until all nets are set. ——— Smiley Social documents: [Group Rules](https://docs.google.com/document/u/2/d/1HrG35p_0M08leRvCp8XWG3CMkr_GL928XFabl5T6Dvg/mobilebasic) [Liability Waiver](https://docs.google.com/document/u/2/d/1W2mq-7m99lmvd7gdWYaSUFtvVg4UGnzV6koafAbHmco/mobilebasic) [Volleyball Levels](https://docs.google.com/document/u/2/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/mobilebasic)

Join us for another session of our study group as we cover the book Build a Reasoning Model (from Scatch). In this session, we will try to cover Chapter 1 titled "Understanding Reasoning Models", which defines what a Reasoning Model is and Chapter 2, on "Generating Text with an LLM". This isn't just a lecture! Come ready to ask questions, share insights, and code along. Whether you're a beginner or have some experience, this is the perfect opportunity to continue to learn together. If you plan to work with the code on your own laptop during the session, try and download the code from it's GitHub repository at https://github.com/rasbt/reasoning-from-scratch ahead of time.

If you’ve already learned the basics of volleyball and want to keep improving your skills while having fun, this event is for you! **Skill Level:** Advanced Beginner (click [here](https://docs.google.com/document/d/1PojSi4qdlRsv1msCHhvpQ43iDc4FfzQwpWCc3kafVMY/mobilebasic) for details). **Reminders** 1. Attendance: We’ve noticed that the waitlist is growing, so please make sure your name is on the Going list if you plan to play. Our number of nets is limited so this helps avoid too many rotations. If your name is on the list but you don’t show up, it will count as an absence according to Smiley Social rules. Please update your RSVP at least 12 hours in advance if your plans change. 2. Waitlist: The waitlist is not first come first serve. We prioritize regular attendees, and will fill empty spots with new faces closer to the event date. 3. Injuries: Play safely and be mindful of others on the court. Respect positions and avoid risky moves that could lead to injury. If you’re not sure the ball is yours, call it before going for it to avoid collisions. 4. Game Rules: Let’s follow the basic volleyball rules, especially the three-touch rule so we can play properly and improve as a team! **Smiley Social documents:** 1.

Hello again! After a long hiatus, the Monday meet up at Nanny O’Briens is back! We’ll have some games to play, but feel free to bring your favorites as well. Stop by for a game and a drink, and say hello! We’ll be in the back room. Other info: Nanny O'Brien's is allowing us to use their back room for some board game socializing. Please reciprocate their generosity by purchasing food and drinks. Free street parking starts at 6:30 in most areas (make sure to read the signs). If you're taking the metro, take the red line to Cleveland Park and walk two blocks southwest on Connecticut (we are located next to CVS).

We are NPS Weed Warriors and Arlington Regional Master Naturalists and you should volunteer with us on Sunday, May 17 to learn about nature and remove invasive plants from everyone's favorite urban island. Meet us at the entrance to the bridge (on the parking lot side, look for the sign) at 10:00 and bring your garden gloves and loppers/pruners if you have them. If not, we can provide gloves and tools. Wear long sleeves and pants and don't forget a water bottle. We will have tasks ranging from easy (cutting English ivy and honeysuckle vines from trees) to hard (sawing down bush honeysuckle). Parking at TRI can be tight if it's a pretty day. When the parking lot is full, you can park in Rosslyn and take the trail down. If you can bike or walk or take public transit, that's wonderful. We'll see you there! Erica, Stephanie, and Heidi P.S. If you can't wait until then to RIP (Remove Invasive Plants!), go here to find more volunteer opportunities in Arlington parks: [Volunteer to Restore Native Habitat – Arlington Regional Master Naturalists (armn.org)](https://armn.org/volunteer-opportunities/)

Join the Jaycees in volunteering at the Arlington Food Assistance Center (AFAC)! We sort donated canned goods or bag portions of dry goods or produce for AFAC's weekly food distributions to low-income families in Arlington. AFAC is a long-time community partner of the Arlington Jaycees! At 2:30, or when we are done at AFAC, we will head to **Guapos** in nearby Shirlington for food and drinks. So that we can appropriately plan the tasks to do for the right number of volunteers, **PLEASE UPDATE YOUR RSVP** as soon as possible whether or not you are able to attend. We have to limit the number of volunteers due to limited space at AFAC, and don't want spots to be taken by people who sign up but don't show up. AFAC is located at 2708 South Nelson Street and Four Mile Run Drive. There is street parking available near the building although parking spots are limited. The Volunteer Entrance is the GRAY DOOR by the loading dock. Volunteers must wear closed-toe shoes (no sandals or flip-flops) and must have your hair covered while bagging food. You can bring a hat from home or AFAC will provide disposable hairnets. The Arlington Jaycees (part of Junior Chamber International) is the premier nonprofit in Arlington that provides young people (ages 21-40) with opportunities for personal & professional growth, business networking, community involvement and social engagement in the Arlington Community and worldwide. Our mission is **leadership development through community service**.

Title: What Is Progress? Knowledge Aggregation, Living Textbooks, and the Automation of Scientific Discovery Date: June 20 2026 Noon - 14:00 EDT Summary: Our collective knowledge infrastructure — the textbooks, professional training resources, and literature syntheses that define what professionals across disciplines believe to be true — is quietly accruing a structural liability. Compounded confirmation bias, stacked citation-by-citation into the foundations of formal knowledge, means that breakthroughs can take decades to reach the classrooms, clinical workflows, and decision-making frameworks where they matter most. Meanwhile, the deepest friction is rarely acknowledged: before any field can build meaningful consensus on "why" or "how" a phenomenon occurs, it must first establish honest, consolidated agreement on "what" has actually been observed. That prior step is routinely skipped, assumed, or fragmented across siloed literatures that never cross-pollinate. This talk introduces a framework called "Knowledge Aggregation" — with two distinct but complementary ambitions. The first is descriptive transparency: algorithmically mapping what has been said, measured, and documented across a problem space, without imposing causal interpretation or narrative. The second traces the boundary between empirical observation and explanatory claim, building systems that can separate the "what" from the "why/how" — because consensus on mechanism cannot be meaningfully constructed until consensus on phenomenon is first established. Both ambitions are now within reach. By composing tools already at our disposal — large language models, classical NLP pipelines, public data repositories, and engineering-grade automation frameworks — it becomes possible to model knowledge itself, rather than merely imitate individual experts. One concrete expression of this is automating the writing of living textbooks: compressing the lag from bleeding-edge discovery, through replicated evidence, all the way to professional training resources. But the deeper aspiration reaches further — toward automating the discovery of scientific insights that have never previously been conceived, by systematically surfacing hypothesis combinations that no single siloed researcher would have had the cross-disciplinary vantage point to even ask. Drawing on ongoing systems biology and computational research — with ME/CFS research demoed as a use case for what siloed, fragmented knowledge infrastructure costs in practice — this talk maps the conceptual architecture, the real-world friction, and the data science toolkit for building it. Speaker: As a systems biologist at heart, Sam specializes his biomedical research on interactions and connections in biology - rather than just one domain of expertise. He wears many hats and collects skill sets across disciplines, with degree studies and industry experience acquired across Chemical Engineering (BSc), Bioinformatics (MSc), Systems and Synthetic Biology (M2), Biomedical Sciences (MSc), and beyond. Even more important to him than niches or fields of work, comes down to the synergistic approaches that allow us to move beyond reductionism. The notion that a question can only allow for one answer, is inherently reductionist. By resisting many norms in science and engineering which can get overly reductive, his current role as Principal Investigator of Research for DMV Petri Dish (501(c)(3) non-profit local to the DMV region) embraces computational frameworks that aide scale-up and automation - not only around the processes which already exist with established workflows, but also taking a keen interest in attempting and accomplishing ambitions which have never been perceived to be possible previously. Sam carries a passion for the synergy of computational biology - fused with wet lab validation. This way, one can build a beautiful knowledge base in the theoretical sense, and then test to see if said computational prediction might actually be able to stand in the real world with wet lab validation. Translational modeling starts to become possible once biological experiment design can be iteratively looped alongside computational model design, optimization, and analysis - empowering the design of a better wet lab experiment, followed by a better computational model, back and forth until science is done!

**Self-Proclaimed Trivia Master, Paul, has all the questions AND answers**: All YOU have to do is bring the answers. Easy? Let's find out in the next rendition of Trivia Night. Let's warm up with the question that I like to ask to establish your knowledge of current events and IQ. Don't be shy. Shout this one out. What happened in April in America that had not happened since 1972 ? (warm up questions answer is posted at the bottom) Okay, not bad. I heard that. RSVP and form up into teams of up to 4 people when you show up. Compete for prizes so large we had to park them at the airport. Prizes will be awarded for 1st, 2nd, 3rd place and Dead Last (that one's more of a remedial learning aid, but it will be fun. I promise). **On Freestyle night** \- just bring a bottle to share\. There is NO formal wine tasting like on other weeks\. Door charge is $10 \(cash or Venmo only please\)\. We may have some left over wines to clear out\! Glasses are provided\. Take Care\. See you there\. **Parking**: There are several public parking lots near the Alive614 hall. Please be careful to NOT park in private parking lots. They do tow. Check Google maps to scope out your space. Anyone who is early could easily find a parking space on the street nearby. I am told that the Chase parking lot is safe after hours. **Glasses**: …will be provided. Please note that after the wine tasting, the EMPTY glasses need to be returned to the boxes at the service table. Please do not make me hunt down your empty glass. Please be gentle, our glasses are fragile. Uh, they are made of glass! (ps - empty the glasses into the sink, not the trash ... please) **Food**: You are welcome to bring a snack to share. It is not required. Most people do though. If no one brings anything, there will be nothing. **Code of Conduct**: Though mostly understood, it’s still worth mentioning. We don’t have rules per se, but we highly discourage the following topics of discussion because they are likely to incite anti-social responses - Sex, Politics, Religion. Please don’t mistake this as an attempt to limit your free speech rights but rather a guide to a place and time for appropriate discussions. **After the lights go out**: After the last sip of wine, when we clean up and turn the lights out, if you still haven’t had enough of us, it is typical for a group to get together and go to a local eatery for food and/or drinks or coffee. Again, We look forward to meeting new members and reuniting with old friends. Sincerely, ***Paul Uttermohlen***, **Red 1 Realty** *Your Hilliard Wine Club Host* **Answer**: *That's right!* / We sent a rocketship with live astronauts to the moon for a quick lap around our only natural satellite. They didn't land. And they never got out of the capsule... for 10 days! Been there. Done that! (It's like they're replaying all the greatest hits from my childhood.)

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. Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went? Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence? Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp.
