Join me and our member Yazmin M for a Sunday afternoon hike at Windy Run Park in Arlington! Getting to the waterfall at Windy Run is a fun little adventure right in Arlington! Most of the walk through the woods is nice and easy, but we will hop on some rocks to cross a couple of streams and go down a set of steep steps alongside the 35 foot waterfall. Yazmin says: I usually take my time going down as my left knee can be achy at times :) The hike should take about one hour and fifteen minutes. Wear shoes with good grip, and bring a water bottle, and mosquito repellent. We will meet by the park entrance on N Kenmore street. Yazmin recommends you park on the cul-de-sac around 2455 N Kenmore St, Arlington, VA 22207. Let us know if anyone needs a ride from Metro, we'd be happy to help with carpooling. Hope to see you!

**This talk has completely sold out in advance and no additional tickets will be sold at the door. A repeat of the talk at Penn Social in DC on Monday, May 18 still has tickets available.** [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.)

[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.)

This coming Sunday promises to be like early summer, so dress accordingly and don't forget to bring bug spray and sunscreen. Starting from the Tenl;eytown Metro Station at noon, we’ll first walk down to the Glover-Archbold trailhead on Van Ness Street and head south along a dirt trail. After a few miles we’ll turn east on the Whitehaven Trail., which is surprisingly rough for a short stretch. We will stop for water and a bathroom break at the Trader Joe's on Wisconsin Avenue. Then we’ll continue through Dumbarton Oaks to the Rock Creek trail, where we'll head north. That's a dirt trail until Connecticut Avenue, where it will become an asphalt trail that will take us past the Zoo and eventually to Peirce Mill, scene of Saturday's annual Picnic. A short distance later we’ll head up the Soapstone Trail to Connecticut Avenue, which we'll take southward to our ending point at the Van Ness Metro. Nearby you can enjoy optional beers at the Dog Haus Biergarten Van Ness (website: [https://locations.doghaus.com/locations/dc/washington/4340-connecticut-avenue-nw-retail-space-5](https://locations.doghaus.com/locations/dc/washington/4340-connecticut-avenue-nw-retail-space-5)). Total length of this moderate to strenuous outing is about 8.5 miles. We meet at noon in front of the Panera on Wisconsin Avenue @ Ablemarle Street, near the eastern exit of the Tenleytown Metro Station. We should finish by 4:30 p.m. Bring plenty of water, snacks, bug spray, sunscreen, and the $5 Adventuring trip fee (cash or Venmo). Please [click here](https://adventuringlgbtq.com/Adventuring_Release_Form.pdf) to review our release form. When you RSVP to an event, you affirm that you have read and agree to the terms of the release.

Hi ladies. We will meet in front of the Nature Center and head to the two Observation decks. We will then hike Hickory Ridge, Ripple Rock, Overlook and Sugarbush trails to get approximately four miles total distance. We will walk approximately a 18 minute mile pace. Please wear appropriate hiking shoes.

**Not everyone will come. That is exactly why you should.** **Two for Tuesdays** is for the people who actually want to get out and do something instead of just talking about it. We’re kicking off the night with a one-hour social walk before Duckpin Social. **Expect a laid-back** But an Intentional 1 hour walk (2-3 miles), good people, and a better way to spend your Tuesday than staying home and doing the same thing you always do. **If the weather does not cooperate, we’ll move indoors.** **This is a paid event.** A small contribution helps keeps events sustainable and ensures those **who RSVP actually show up.** Payment **Link Found in comments** or you can pay on Venmo, Paypal, @WiseUnlimitedLLC or Cashapp $WiseUnlimitedLLC. Walk RSVP **$2** Walk / DuckPin Social **$5** Walk / DuckPin Social + 1 game of duckpin **$12** Please be sure **to Put Event and Event Date** in the note when paying RSVP Fee

We'll get in around 4 miles at Three Creeks Metro Parks, primarily natural trails. 17-18 minute miles, no one left behind, and faster walkers are free to lead out. Optional lunch after! If you're joining for hiking all the metro parks, this is the sixth one!
