Join Late Morning Hikers to learn about the history of one of our regular haunts — the Appalachian Trail! We will nerd out together at a Profs and Pints talk at Penn Social — see description below. You must buy a ticket to attend — they’re about $16 in advance after fees. We’ll meet at 6pm (a comment will be posted on this page with a description of where we’re seated in the bar) and the talk starts at 6:30pm. Link to buy tickets: https://events.ticketleap.com/tickets/profsandpints/appalachian-trail Event description from Profs and Pints: Profs and Pints DC presents: “The Course of the Appalachian Trail,” on the fascinating past and uncertain future of a beloved wilderness trail and national park, with Mills Kelly, emeritus professor of history at George Mason University and author of A Hiker’s History of the Appalachian Trail. Spring brings people flocking back to the Appalachian Trail, which for more than 100 years has provided opportunities to spend anywhere from a few hours to six months traversing the Appalachian Mountains. Stretching more than 2,000 miles across 14 states, from Springer Mountain in Georgia to Mount Katahdin in Maine, it ranks among the most iconic long-distance hiking trails in the world. It and its associated national park are annually visited by nearly 17 million. Gear up for Earth Day—and perhaps some time on the trail yourself—by spending an evening with Mills Kelly, an expert on all things Appalachian Trail and is the author of two books and numerous articles on the trail’s history. We’ll start our scholarly journey by looking at the trail’s origins. First proposed by Benton MacKaye, a forester, in 1921 as a place for urban workers to get some fresh air and sunshine, the trail took 16 years to scout, map, and carve out of the mountains. The first version was woven together mostly from abandoned mountain roads, Indigenous people's paths, and highways. Drawing on research in archives up and down the length of the trail, Professor Mills will show us archival photographs and video clips spread across the decades of the trail’s history, and he'll let the voices of hikers themselves describe how the experience of hiking has changed over the decades. You’ll learn what hikers ate before the advent of freeze-dried backpacker meals and when and why thru-hiking became a thing. More profoundly, we’ll examine how innovations in gear changed the experiences of women on the trail, and how changing attitudes about race transformed the hiking community. Professor Mills will describe how the trail is maintained entirely by 33 volunteer clubs, including the D.C. area’s Potomac Appalachian Trail Club, founded in 1927 to help build it. Looking ahead, he’ll discuss how the trail’s long-term health as a recreational resource is being affected by declining federal support, overuse in some sections, and climate change. (Advance tickets: $13.50 plus sales tax and processing fees. Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

Have you been thinking about trying self-defense training, but do not want a loud, aggressive, or overly competitive environment? This free intro class is a simple way to get started. Maryland Systema offers practical self-defense training for adults in Rockville with a focus on movement, awareness, breathing, posture, and calm under pressure. This class is designed for beginners and first-timers who want real-world self-defense training in a welcoming setting. You do not need experience. You do not need to be in top shape. You do not need a martial arts background. You just need to show up ready to learn. This is not a sport-based class built around winning points, memorizing routines, or trying to look impressive. It is a more practical approach to adult self-defense training that helps you stay balanced, aware, and functional when things feel uncertain. If you have been searching for self-defense classes in Rockville, beginner self-defense near you, or practical self-defense training for adults, this class is a good place to start. **What you will work on** * Breathing and staying calm under pressure * Movement that improves balance and mobility * Awareness and posture * Simple partner drills * Practical self-defense training for beginners **Who this class is for** * Adults new to self-defense training * Beginners looking for a low-pressure class * People who want practical self-defense instead of sport martial arts * Adults in Takoma Park, Silver Spring, Rockville, and nearby areas looking for realistic self-defense classes **What to wear** Please wear comfortable workout clothes. No uniform is required. **Why start with this class** This free intro class gives you a chance to experience the training, meet the group, and see whether Maryland Systema is the right fit for you before joining regular weekly classes. **RSVP** Reserve your spot and come try a beginner-friendly self-defense class in Rockville.

[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Doom and Dinosaurs,”** a look at how mass extinctions shaped the dinosaurs and what research on these events tells us about Earth life’s long-term prospects, with Ian Wilenzik, paleontologist and visiting assistant professor of biology at George Washington University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-doom-and-dinosaurs](https://events.ticketleap.com/tickets/profsandpints/dc-doom-and-dinosaurs) .] Pity the poor dinosaurs. They lacked both scientific research to help deal with potential environmental catastrophes and places where they could have a beer and discuss it. You, on the other hand, have the opportunity to come to Profs and Pints to hear a fascinating talk on the impact of mass extinctions on dinosaur evolution and what research on dinosaurs tells us about biodiversity and Earth’s current biodiversity crisis. Dr. Ian Wilenzik, who has studied and taught courses on dinosaur evolution, population spread, and extinction, will leave you with a greater appreciation of the resilience of life on earth and how we’re both the product and source of biologically catastrophic events. Many of us are familiar with how a big meteor impact about 66 million years ago wiped out the Earth’s dinosaur population, leaving us only with their feathered descendants, birds. Less well known is how the Earth actually has undergone five periods of mass extinction that wiped out nearly all life, and how dinosaurs arose from one and endured another—both caused by volcanic activity—before meeting their match in the third. To ground his discussion, Dr. Wilenzik will talk about how we study mass extinctions by looking for geologic evidence of volcanic activity, meteoric blasts, and other catastrophic activity and of gaps in the fossil record after them. He’ll also discuss what makes a dinosaur a dinosaur, describing their distinct anatomical features. He’ll talk about how they and other forms of life evolved over long periods of time and were affected by extinction events. We’ll look at how the meteor-caused mass extinction that wiped out dinosaurs at the end of the Cretaceous paved the way for the rise of mammals and the emergence of primates, and, eventually, us. Looking ahead to future mass extinctions and what might survive them, we’ll talk about how that plant you forget to water might have the last laugh, as well as why crocodiles might be around a while.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation?
