20's

In the spirit of a 19th-century salon, this gathering will be a space for lively conversations, fascinating encounters, and the exchange of ideas over drinks. Whether you’re new in town or a local looking to expand your social circle, this is the perfect opportunity to connect with like-minded explorers of Berlin’s nightlife. Each week, we shine a spotlight on a **special guest** from our community — someone who brings along a topic they’re passionate about or deeply engaged with. It’s not a presentation or a performance, but rather a gentle invitation into conversation: a starting point for curiosity, questions, and unexpected connections. The topic can naturally weave its way into the evening, without needing to take over. If you’d like to be our next special guest, feel free to reach out via the contact form: [https://socialbutterfly.berlin/contact/](https://socialbutterfly.berlin/contact/) This time, we’re excited to introduce **Erik**, who’s been thinking about how we meet new people in a digital world. Erik has been developing his own app, inspired by the idea of making spontaneous, local gatherings more visible — and connecting with what’s happening around us in the moment. How do you usually meet new people — and what makes you stay in touch? Orga The location is cash only. It is non-smoking (with a separate room for smoking). We’ll be sitting on the couches in the first room. Questions?

Many have started to draw in our event actually. **Structure** A. Warmup Phase: We pose to each other for 1 minute. B. Main Phase: We pose to each other for 10 minutes. C. Showcase Phase: We show some of the drawings we did to each other. **Who We Are** Creative Sessions is an art events group located in Berlin. **Is it Free?** The event is free of charge.

[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.)

Let's go for a hike along the C&O Canal Trail! It's been a while since our last hiking event, so this is a great way to get outside and enjoy the spring scenery. Although certain sections of the C&O Canal Trail present moderate to challenging terrain, this event will primarily utilize the more accessible, easier paths. Nevertheless, we are open to adjusting the route based on the group's preference for a more adventurous experience, including steeper inclines or longer distances. It's recommended to bring hiking boots, a water bottle, and snacks like trail mix or granola bars to keep your energy up. The entrance fee is $10-20, so it is recommended that you carpool if needed. We will rendezvous at Vienna Metro Station Parking Lot at 9:30 AM to discuss the carpooling situation before heading over. \*If the weather calls for rain that day, we will postpone it to a later date.

Regular coffee meetup for people to meet, make new friends, or enjoy general conversations with coffee. Great for those who are new in town or looking for new activities to do! This will be held at Weird Brothers Coffee at Worldgate Centre in Herndon. Afterwards, if anyone is interested, we can grab lunch at whichever nearby restaurant in the shopping center. There’s a TGI Friday’s, a Thai place, a Mexican place, Inchin’s Asian fusion restaurant, and we are open to alternative preferences. Additional Note: If you are on the Wait List, you can still feel free to attend if you wish.

[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.)
