Join us before the lecture for a casual get together to mingle and chat about science! You can get excited about the lecture, talk about previous lectures, indulge in completely unrelated science, whatever tickles your fancy! We'll hang out at The Board Room for about an hour and a half then make our way to the Powell Auditorium. There's no kitchen at the Board Room, so feel free to bring any snacks or dinner with you! There are, of course, drinks available. As this is a bar, this will be a 21+ unofficial gathering.

📚 Do you love reading, but wish you had a structure and a community to share your insights with? Join our small circle of curious minds (just 4 members per gathering) as we come together for an hour of focused reading—in the calm setting of a library or the cozy atmosphere of a café. Here’s how it works: First part: Quiet reading on your own—bring a book you’re exploring, whether it’s philosophy, history, psychology, literature, or anything meaningful to you. Second part: We regroup and each person shares key takeaways, insights, or questions sparked by their reading. This sparks a structured yet free-flowing conversation around ideas, perspectives, and personal reflections. Why join? Add structure to your reading habit. Discover new books, authors, and ideas through others’ choices. Build real connections by sharing and listening deeply. Socialize around something meaningful instead of small talk.

LInden, VA Forecast: https://forecast.weather.gov/MapClick.php?lat=38.9229&lon=-78.0881#.YzbHTiUpAlQ Join me on this moderate to moderately strenuous hike that ventures into the G.R. Thompson Wildlife Management Area (WMA) in Linden, VA. We will hike on the Appalachian Trail and turn around after a break at the Manassas Gap Shelter. With a steady climb at the beginning of the hike, we'll get a good workout with over 1,000 feet of elevation gain in the first two miles. No WMA access permit is needed because we don't leave the AT. There is an intermittent stream crossing, typically an easy rock hop when water is present. We typically hike about 2 mph. However, we leave no one behind and will move at a pace that is comfortable for all. NOTE: I will be carrying a bag to gather any litter near the shelter and its access trail, which I maintain. Join me if you wish. If there is hiker interest, I can demonstate how to hang a food bag on the shelter’s bear pole and/or answer questions about trail maintenance. **Wear BLAZE ORANGE for hunting season.** **Hike Route:** https://www.alltrails.com/trail/us/virginia/manassas-gap **Group Size:** 20 hikers **Time to Meet:** Please meet 15-20 minutes before the hike start for introductions and liability waiver sign in.

Like many shelters along the Trail, the Manassas Gap Shelter resided on private land for many decades. Built from chestnut logs, the shelter is a simple lean-to with three walls. Until the 1980s, there were also bunks across the back of the structure, but these were removed in the 1980s during a restoration of the shelter brought on by a severe infestation of mice and field rats. A spring is just downslope from the shelter.

Title: Biology-Inspired Neural Networks with Multi-Directional Propagation of Values and Distributions Date: Feb 8 2026 10:00 am - Noon EST Summary: While biological axons can propagate in both directions, current ANNs are focused on unidirectional propagation. Also usually they only propagate values, while uncertainty is shown also crucial for making decisions of biological organisms - suggesting to propagate also variance, probability distributions. I will talk about novel KAN-like approach to ANNs repairing these lack by using neurons containing inexpensive local joint distribution model as polynomial, allowing to freely change propagation direction by just switching indexes, also propagate entire probability distributions represented by vectors of moments. Beside backpropagation, it also allows many additional training approaches, like direct estimation, tensor decomposition, and through information bottleneck. Speaker: Dr Jarek Duda is an assistant professor at Jagiellonian University. He holds degrees in computer science (PhD), mathematics (MSc) and physics (PhD). He is mainly focused on physics foundations, information theory, statistical analysis, and is known for introduction of asymmetric numeral systems.

Dale Gnidovec, Curator of the Orton Hall Museum of Geology at The Ohio State University, will be presenting a program he has wanted to share with us for a long time: Plate Tectonics. His description of his program: Continents on the move - Nothing in Earth history makes sense without moving continents - it tells us why mountains, volcanoes, minerals, and fossils are where they are. This talk examines the evidence for continental drift, why it was disbelieved, and explains how the more-encompassing theory of plate tectonics was developed and eventually proven. Dale is an energetic, incredibly knowledgeable, and very entertaining speaker and this will be another wonderful program by Dale. Hope to see you there! Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Going forward our meetings will be hybrid.
