Members of the public are invited to view the wonders of the universe through the telescopes of NOVAC volunteers at the Smithsonian's Udvar-Hazy Center in Chantilly, VA. You do not need to be a member of the club or own any astronomical equipment to attend. Telescopes will be provided by the Smithsonian and pre-approved members of the NOVAC. No other personal telescopes are permitted at the event. The event will take place on the bus parking lot of the museum. **Please park your vehicle at the south end of the main visitors lot and follow signs and red lights to the observing site. As a reminder, parking during the event is free.** Have a cosmic question? One of NOVAC's astronomers or museum staff will be happy to help you. As the sky gets dark, be prepared to enjoy the wonders of the night sky! Don't forget to dress warmly. Please check the weather forecast. For lighting, cover a flashlight in red cellophane (the darker the better). Bring along water to keep hydrated. Note: This outdoor event is weather-dependent and may be cancelled because of significant cloud cover or precipitation.

[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.)

Please join RBAC for our annual Ride of Silence starting in the plaza in front of the Rockville Public Library. Please plan to gather by 6:40 for the dedication and briefing. We will promptly roll out at 7 pm. This is a police-escorted ride in memorial of cyclists killed or injured while riding. You must have a helmet and be able to ride at a 10-mph pace. We will be riding a 9-mile route thru neighborhoods streets and on I-355/Rockville Pike. Front and rear lights are also strongly recommended. The Ride of Silence takes place on public streets and in mixed traffic. This ride is only recommended for bicycle riders who can maintain at least a 10-mph pace and can comfortably ride on the street along side motor vehicles. Since there will be a police escort, we will not be able to wait for riders who have fallen behind. Riders not able to maintain the pace will likely have to complete the route separately on your own. This ride is not recommended for families or children who are not experienced riding on public streets. Please pump up your tires, check your brakes, lube your chain, and take your bike for a test spin before you arrive. More details about this global 24th anniversary event can be found at: [https://rideofsilence.org/main.php](https://rideofsilence.org/main.php) READ THE FINE PRINT, PLEASE: • Bicycling involves inherent risks and requires that participants be in proper physical condition. When you RSVP "yes" to a Bike Rockville event, that RSVP is your digital signature attesting that you have read, understood, and agreed to the group's Liability Waiver and Release, located here: [https://drive.google.com/file/d/1BocKiaMJwba62c7b583CoOxIYamFiaWN/view?usp=sharing](https://drive.google.com/file/d/1BocKiaMJwba62c7b583CoOxIYamFiaWN/view?usp=sharing) • HELMETS ARE REQUIRED for all riders on every ride. • We strongly recommend you bring a water bottle, spare tube, cell phone, ID card, and cash or credit card for emergencies. • Since this part of a global movement , this ride goes on rain or shine!

**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!
