[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.)

Tuesday Night Women's+ Ride at Wakefield This is the women's+ night ride at Wakefield Park in Annandale, Virginia. Brought to you by MORE. **Sign the ride waiver here:** [https://x.gldn.io/e/Wc3cUSEpC1b](https://x.gldn.io/e/Wc3cUSEpC1b) Ride Leaders Simona, Kathy, and Jessica Location Wakefield Park, Annandale, VA Schedule Meet up at 6:30 in the last parking lot. Park in the last parking lot. After you turn into the parking lot, make an immediate right and park (across from the purple recycling bin). We meet there prior to the ride. All riders joining this ride will need to accept the standard MORE liability waiver form. **Wheels down at 6:45pm** Ride will be about 1 to 1.5 hours, depending on the group. The ride leader(s) will try to start as promptly as possible. Bring: Trail-ready mountain bike, helmet, tube, and water. Optional: Tools, gloves, snacks, and lights. We will need lights this time of year. Pace Casual to moderate pace depending on the group. This is a no-drop ride. (A drop is leaving someone behind who is slower than the group. We won't do that - but if you feel like you are not able to keep up, please let the ride leader know.) All riding abilities are welcome, but it is recommended riders have a few off-road rides under their belts first. Terrain Wakefield is generally considered easier to intermediate by most riders. There are a few small stream crossings and some log obstacles. Riders should use good judgment and dismount when in doubt. The ride will typically consist of a mix of single track, fire roads, and other trail sections in the park.

[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.)

Let’s kick this off at Sully’s Pour House in Herndon on Wednesday the 20th. There is free parking in the back ('Municipal’ lot). The game starts at 7 but try to be there by 6:45 to pick categories. We’ll be getting in around 6:15 to try for a ‘high’ table, and you’re welcome to join us. We do tend to leave when the game finishes, but no one else has to. Team size is limited to 6, so only sign up if you can make it – and please remember to cancel as soon as possible If something changes. Look forward to seeing you!
