Chemistry

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.

The 4th Annual Cyclists Bowling League is here. Come enjoy hanging out and watching your favorite cyclists from your favorite cycling clubs as we eat, drink and talk trash while enjoying a little friendly competition. This time we're rolling strikes not bikes. Have questions? Want to join a Club's Team? Or maybe your club wants submit a team? We can help you with that but time is limited so act quick. Message us so we can get you started The League is held at Crofton Bowling Center every Friday beginning at 6p.

Venez apprécier l'ambiance chaleureuse d'une conversation en français autour d'un verre de vin et d'apéritifs. C'est ouvert à tous quelque soit votre niveau, que vous soyez intermédiaire/avancé ou bien que le Français soit votre langue maternelle. ***GRAB A DRINK AND YOU WILL BE ALL SET TO FLEX YOUR LANGUAGE CAPACITY. YOU NEED TO GET AT LEAST A DRINK OR FOOD :) To get the event going and show support. We know that you like our events. P.S. : We have non-alcoholic drinks as well.*** We have a tiny venue and we hit capacity often and early arrival is suggested. We have the discretion to decide entry. It is irresistible, to enjoy French convo with a glass of wine, appetizers and drinks. The Event is open to all levels of French language, from intermediate to native fluency. This is mainly a social for Intermediate/Advanced/Native Speakers. It is not as such to learn a language. Beginners, if you want to learn a language, reach out to us ([info@merevents.com](http://info@merevents.com/)). We have a school and will arrange you a class. ***AFTER THE HAPPY HOUR, WE HIT THE DANCE FLOOR! BRING YOUR DANCING SHOES, WE WILL DANCE THE NIGHT AWAY!***

This Happy Hour is devoted to professionals in the International Affairs and Development community, to grow, interact, and learn from each other. It is designed to provide a professional environment to meet other International Affairs professionals to broaden one's career. It is also for those interested in International Affairs and Development careers and are studying or intend to enter the dynamic world of global development. HOW IT WORKS : We will try to assign tables for each represented INDUSTRIES/SECTORS/SPECIALIZATIONS and will direct attendees to their respective tables accordingly. All industries are welcome!

Join us to discuss Wuthering Heights by Emily Bronte. We will be meeting in the food court, look for the table top sign with our group name. The book discussion will begin promptly at 3. If you’d like to purchase food/beverage, please plan on arriving early to do so.

**Drop-ins are allowed (you don't have to attend every week) but an RSVP is required so you receive the Zoom link. It's the same link for every class!** **Sign up here:** **[https://harringtonmatchmaking.as.me/constellations10](https://harringtonmatchmaking.as.me/constellations10)** Join a virtual group that meets on Wednesdays + Sundays and focuses on conversational skills, building early friendship and dating confidence, and so much more for neurodivergent adults. All are welcome, but this group is designed especially for autistic adults with little to no relationship experience and those who struggle with holding conversations or making new friends. The group is currently open at no cost to Neurodivergent District members but is part of the [Constellations program by Harrington Matchmaking](https://www.harringtonmatchmaking.com/constellations-membership). Currently, most participants are between ages 20 and 45 and are members of Constellations so they've signed up through the website. Many live with family, in supported or semi-independent housing, College Living Experience programs, or similar settings, and are looking for a safe, low-pressure place to practice conversation. Sessions are coach-led and structured. This is not a free-form discussion group. Each meeting includes guided practice, clear coaching, optional weekly sharing, and supportive feedback. The majority of the sessions are virtual, with occasional in-person meetups once a month on weekends in the Washington, DC area. **Drop-ins are allowed (you don't have to attend every week) but an RSVP is required so you receive the Zoom link.

Date : Feb 7 2026 13:00 - 15:00 EST Title: Symmetry, Topology, and Magnetoelectric Multiferroicity — Ferroelectric 'Tweezers' for Quantum Magnetism in Hexagonal Ferrites Abstract: The scalability of future quantum and spintronic hardware is currently facing a "physical wall": the challenges of excessive heat dissipation and environmental magnetic noise. To overcome these barriers, materials where magnetism can be controlled with high precision and minimal energy will be highly desirable. Magnetoelectric multiferroic hexagonal rare-earth ferrites (h-RFeO3, R: rare earth) have emerged as an important platform for this mission, offering a unique "playground" where symmetry and topology dictate functionality. In this talk, I will provide a comprehensive overview of research progress on these materials over the last decade. We will explore how a specific structural transition—trimerization—breaks symmetry to create a robust state known as improper ferroelectricity as well as weak ferromagnetism. The coupling between the ferroelectric and magnetic orders leads to a "ferroelectric tweezer" effect, where the material's ferroelectric domain spatially anchors and manipulates magnetic domains. Furthermore, we will address the "readout challenge": how to detect the diminutive magnetic moments inherent in these systems. I will show how the non-coplanar spin topology acts as a signal amplifier, enabling high-fidelity readout of magnetic states through spin-transport. By understanding the "solid science" of these complex oxides, we can define the roadmap for a new generation of stable, low-power topological electronics. Biography: Xiaoshan Xu is Susan J.

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.

Hey Chapter Twoers, one of my New Years resolutions was to be more creative in choosing restaurants for our events this year. Kitchens + Kocktails fits the bill. Here's how the restaurant describes itself: "Kitchen + Kocktails by Kevin Kelley is revitalizing how the world experiences elevated southern comfort food. Whether you have a taste for classic soul food entrees such as shrimp and grits, southern fried catfish or modern soul food options like chicken and waffles, jerk lamb chops, or a fresh lobster tail, Kitchen + Kocktails by Kevin Kelley will serve it and your experience will be one of high care and quality." I'm excited to try it. Come join me!

This is a time where players of all ages, and skill levels can gather and enjoy a nice Sunday full of Chess!
