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.

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!***

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.

**Join us in Falls Church for conversations that go beyond small talk.** Higher Grounds – Falls Church is where this growing network of gatherings began: a space for thoughtful, authentic dialogue about what matters most.

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. Moderators: Dr. Pawel Gora, CEO of Quantum AI Foundation and Dr. Sebastian Zajac , member of QPoland Zoom registration form will be provided no later than 1 hour prior to the event's start time.

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.

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.
