You can build a railroad, eradicate a plague, or explore the far reaches of the galaxy in one evening. While many will bring their own games, you can show up gameless and still play. We play at the Ballston Quarter mall basement food court on Wednesday from 6:30-10:00. It's within walking distance from the Ballston metro and there's parking in the garage for $1. **Find us at the tables to the right when you get off the elevators to the lower level.** Look for a group that has containers and carrying bags with multiple games.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“How AI Alters Thinking,”** on dealing with artificial intelligence’s capacity to change and undermine our thought processes, with Eli Alshanetsky, assistant professor of philosophy at Temple University, principal investigator at its Cognitive Integrity Lab, and author of an upcoming book on AI and freedom of thought. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-how-ai-alters](https://events.ticketleap.com/tickets/profsandpints/nv-how-ai-alters) .] Doctors who give bad advice can be sued for malpractice. Teachers belong to a profession with set standards. When artificial intelligence guides you, however, that guidance comes with a disclaimer: Use at your own risk. Every day millions of people take that risk, and usually AI seems genuinely helpful. But even if AI gives us good answers, might its use over time do bad things to how we think? Explore the relationship between AI and our own minds with Eli Alshanetsky, whose Cognitive Integrity Lab studies how artificial intelligence changes how we think, learn, and build trust. Author of *Articulating a Thought* and the upcoming book F*reedom of Thought in the Age of AI*, he’s on the cutting edge of efforts to answer AI-related questions such as: How can we tell when work is truly our own? How can technology support rather than replace authorship and reflection? What does trust mean when AI mediates our relationships with others and with our own thoughts? To set up his discussion of potential consequences of AI, he’ll describe how social media’s impact on society serves as a preview. Social media didn’t just give people what they wanted to click on, it actually changed what they regarded as click-worthy. It broke attention spans and fueled radicalization across millions of very different people. It left us with people who doom-scroll for hours, who can’t focus, who don’t know what to trust anymore. If you’d shown people this version of themselves ten years ago, would they have chosen it? Artificial intelligence is making a similar deal with us, but the stakes are higher. It isn’t chasing clicks. It’s optimized for giving you the most satisfying response to whatever is on your mind right now. The risk over time isn’t just that you’ll get lazy. More profoundly, even when you think hard, your sense of what counts as good thinking—as well as what sounds like you—will shift to match what AI has been feeding you. We’ll consider what kind of person this produces and whether this is someone we want to be or want children to become. Professor Alshanetsky will lay out a practical framework, which he calls “the interaction layer,” for using AI without letting it replace the thinking it’s supposed to support. He’ll also talk about what AI-related concerns should be the focus of parents and educators. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

GM Jason will run an Ultraviolet Grasslands session. Stay with me, here: what would happen if we mashed up Oregon Trail with Dying Earth with Mad Max? Well, UVG answers that question (that nobody ever asked) with this heavy metal psychedelic fantascience pointcrawl game. Please the horned catlords by hitching your lime green fox-ocerous pony to your wagon and heading west to see if you can’t trade all this vampire wine for some profit! None of those words will make any more sense to you after playing, probably, but we’ll have an amazing time exploring! This will be way more about the joy of exploration, the tedium of travel, and the thrill of commerce than it will be about battle. If that sounds refreshing, come try something new with us! This might be the first session in a mini-campaign, so we will start with rolling up new characters! New players welcome! No prep needed! **Where**: Your Hobby Place in Old Town Alexandria Looking for a place to play in-person RPGs and make new friends? Burnt out on internet D&D?

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“When Washington Burned,”** a detailed look at the devastating 1814 British attack on the Capitol, with Denver Brunsman, associate professor of history at George Washington University, lecturer at Mount Vernon, and scholar of the American revolution and early American republic. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-when-washington-burned](https://events.ticketleap.com/tickets/profsandpints/dc-when-washington-burned) .] You’ve probably toured several of Washington’s landmarks, but have you considered those that went up in smoke more than 200 years ago? Learn about one of our nation’s greatest scares from historian Denver Brunsman, a favorite of Profs and Pints audiences and expert on the War of 1812, which led to the infamous 1814 attack. He’ll tell the riveting tale of how British troops torched the Capitol and White House and burned down nearly all of Washington’s public buildings. He’ll frame his talk of such mayhem by discussing the origins and significance of the conflict that caused it, the War of 1812. In addition to helping to cement America’s independence, the War of 1812 helped give rise to a sense of nationalism among the people of Canada. It rallied boosters of the city of Washington—among them, First Lady Dolley Madison—to advocate for keeping it as the nation’s capital. With the war’s end, America was free to embark on two centuries of growth. You’ll leave with a much greater appreciation of how our nation has withstood tests in the past and how much of Washington D.C. has been built upon the ruins of previous losses.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“The Physics of Baseball,”** with Scott Paulson, professor of physics and interdisciplinary liberal studies at James Madison University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-physics-of-baseball](https://events.ticketleap.com/tickets/profsandpints/nv-physics-of-baseball) .] Profs and Pints is offering baseball fans an even bigger treat than Cracker Jack, an exploration of the physics underlying their beloved sport. Professor Scott Paulson, who regularly teaches introductory physics classes that make the physics behind real-world phenomena accessible to all, will discuss the forces and phenomena that come into play in baseball during pitching, batting, and fielding. He’ll toss you basic physics concepts that help explain how baseball’s routine plays got to be that way, and he’ll explain what’s going on in some situations where the laws of physics seem to be violated by what’s happening on the field. Ever wondered why curveballs curve or knuckleballs behave so strangely? You’ll learn how Newton’s laws and the Magnus force explain how pitchers get drastically different results from subtle differences in their releases. Curious about what exactly the “sweet spot” of the bat is? Ever wondered how big an advantage batters get from the thin air of Mile High Stadium? We’ll explore the physics of the batted ball, examining the phenomena of waves and analyzing the interaction of ball, bat and batter with the help of high-speed video. During one of the more exciting scenarios in a baseball game—the close play at the plate—fans often see outfielders throw to an infielder rather than directly to home. We’ll look at the pros and cons of this relay play, known as a “cut-off,” in the context of the physics of projectile motion. Finally, we will also look into high-profile cheating scandals involving corked bats and doctored balls. Dr. Paulson will present models to explain how these alterations to the equipment can benefit the batter and pitcher respectively, and he’ll discuss how much these models are backed up by data. These few hours in a brewpub will forever enhance your enjoyment of time at the ballpark. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.)

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Popes and Politics,”** on the history of clashes between pontiffs and world leaders, with Vanessa Corcoran, medieval historian at Georgetown University and scholar of the history of the Roman Catholic church. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/northern-virginia-popes-politics](https://events.ticketleap.com/tickets/profsandpints/northern-virginia-popes-politics) .] President Trump recently shocked many by unleashing personal attacks on Pope Leo XIV, the first American-born pope, in a post on the Truth Social platform. Trump has been widely criticized by religious leaders for these remarks, made in response to the pontiff’s advocacy of peace with the U.S and Israel at war with Iran, and for his separate posts of AI-generated images depicting himself as a pope and as Jesus. For his part, Pope Leo has told journalists, “I am not afraid of the Trump administration,” and has found himself at the center of a heated debate over the proper role of any pope when it comes to commenting on global politics. As unsettling as such developments might be to Roman Catholics, they’re hardly unprecedented. Disagreements between popes and world leaders go back to the Middle Ages, and have played a significant role in shaping the Church and its role in the world. Explore the long history of popes’ conflicts with politicians with Vanessa Corcoran, a historian of the Roman Catholic Church who previously has given excellent talks on papal conclaves and the evolution of nativity scenes. She’ll discuss fascinating developments such as the fourteenth century Avignon Papacy, when Philip IV of France got the upper hand in a feud with the Church by pressuring a papal conclave to select a French pope and then getting the church’s leadership relocated from Rome to Avignon for nearly 70 years. In drawing parallels between recent events and medieval attacks on the Church’s authority she’ll describe how today’s anti-Church memes echo the anti-pope and anti-Catholic images that Martin Luther disseminated in large numbers with the help of woodcut printing. We’ll look at tensions between past presidents and past popes over not just wars, but issues such as abortion, stem-cell research, and abortion access. The talk will leave you with a deeper appreciation of the inherent tensions between politics and matters of faith. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.)

**ProductTank NoVA is back!** After a brief hiatus, we are relaunching the chapter with a format that cuts out the fluff and gets straight to the reality of building. Every product feed is flooded with AI hype right now, but what does it actually look like on the ground? Instead of a polished keynote, we are hosting **0 to 1 with AI: Real Product Talks**—a "Show & Tell" featuring 3–4 lightning talks focused on the intersection of AI and product. The framing for the talks is simple: *"Here is what I'm building, and here is what I'm stuck on."* We want to look at the messy, 0-to-1 reality of integrating AI into your workflows and products. *(Want to share what you are working on? Reach out! The bar is low-pressure, just 10–12 minutes to talk about a real AI problem you are trying to solve.)* **Agenda:** * **5:30 PM - 6:00 PM:** Doors open, networking, & name tags * **6:00 PM - 6:10 PM:** Welcome + Chapter Relaunch Intro * **6:10 PM - 7:30 PM:** Lightning Talks (Three 12-min talks + 5 mins Q&A each, with a 5-min stretch break) * **7:30 PM - 8:00 PM:** Open networking * **8:00 PM:** Soft close **Location & Logistics:** Herndon Fortnightly Library (Extended Hours Meeting Room) 768 Center St, Herndon, VA 20170 * **Parking:** We'll meet at the library, located just behind the Herndon Municipal Center. There is plenty of free public parking available around the municipal center. * **Metro & Bus:** Take the Silver Line to Herndon Metro Station, then connect via Fairfax Connector Route 921 or 950 to Historic Downtown Herndon. * **Driving (via VA-267/Dulles Toll Rd):** Take Exit 10 North (Centreville Rd, which becomes Elden St). Turn left onto Station St or Lynn St. * **Driving (via VA-286/Fairfax Co Pkwy):** Take the Elden St West exit. Turn right onto Lynn St. Looking forward to seeing everyone again and getting back to building!

After hosting successful events, I always think that we could have done better and relate it to our day to day life and make it educational. In this connection, I wanted to show off my investment and trade hat and organize series of Happy Hours around Investment & Trade. We will have speakers from different sectors and industries, at each Happy Hour. At this particular event, the speakers will discuss Avoiding Big Mistakes When Saving For Retirement. Topics will include: • The Effect of Inflation on the value of a dollar • Proper Investment Allocation • Underestimating the Effect of Taxes • Underestimating Spending During Retirement • Unrealistic Investment Expectations • Underestimating Time Spent in Retirement • Mismanaging Tax-Deferred Assets • Unexpected Health-Care Expenses The address will be sent to members who RSVPed, before the Event.
