## Details Hello everyone! We climb at Crystal City Movement every Monday. Please read rest of the description carefully. We mostly do tope rope climbing but we can arrange bouldering sessions as well. If you prefer lead climbing please post on the comments to find your belay partner. \#\# Requirements * If you are not a Movement member, you'll get a daily pass. If you don't have the equipments you can rent them in the gym. * Please sign the waiver through: [https://movementgyms.com/waiver/](https://movementgyms.com/waiver/) * You can get a discounted day pass and free rental gear if you say you are here for my meetup All skill levels are welcome! If you are totally new to climbing and want to do top rope, then you have to have a belay certificate. In order to do that; * You can check Movement gym Intro to Rope Climbing class : [https://movementgyms.com/crystal-city/climbing/classes/](https://movementgyms.com/crystal-city/climbing/classes/) * After the course, you should do the 'Belay Check' which can be done as soon as 24 hours after you take the class. The test takes around 15 mins so it can be done before the climbing session. Before your first visit you may want to check the related webpage: [https://movementgyms.com/first-visit/](https://movementgyms.com/first-visit/) \#\# Where to meet To find us go down the stairs in front of the front desk. We will meet around the benches next to climbing walls.

Climbers of all skill levels are welcome! To join us: 1. Complete the [participant agreement](https://movementgyms.com/participant-agreement/). 2. Pass the belay check, which can be done the same day. See [FAQs](https://movementgyms.com/first-visit/#faqs) for more info. 3. Pay for [gym membership or day pass](https://movementgyms.com/memberships-passes/). The event itself is run by volunteer organizers free of charge. If you are interested but have never belayed before, please take the [Introduction to Rope Climbing](https://movementgyms.com/rockville/calendar/#activity=climbing&location=rockville&class-type=intro-series&area-of-focus=safety-and-belaying) class first. We'd love to climb with you as soon as you know how to belay safely using a GriGri. To find us, go past the front desk and turn left. We'll gather by the fitness room entrance. If you need a refresher on knot tying and/or belaying, please post in comments or message the host and we'll be happy to help. We normally top rope in groups of 2-3 people, but some are also happy to lead. Post in comments or ask on the spot if you are interested in leading.

**This talk has been postponed to March 9th in response to a winter storm. Tickets for the March 9th staging of it are available at** [https://www.ticketleap.events/tickets/profsandpints/dc-wink-nod-kill ](https://www.ticketleap.events/tickets/profsandpints/dc-wink-nod-kill )**Anyone who had purchased a ticket for January 26th will be getting a refund.** [Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Wink, Nod, Kill,”** a look at implicit calls for violence and other speech that leads to bloodshed and threatens democracy, with Kurt Braddock, assistant professor of communications at American University and expert on terrorism. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://www.ticketleap.events/tickets/profsandpints/wink-nod-kill](https://www.ticketleap.events/tickets/profsandpints/wink-nod-kill) .[ Over the last decade, President Donald Trump and many of his allies have used language that implicitly advocates for the use of violence without directing it outright. From telling the Proud Boys to “stand back and stand by” to suggesting that legal acts of Democratic lawmakers should be “punishable by death,” Trump has consistently suggested that violence is a viable means of addressing political grievances. Support for political violence—implicit or explicit—goes beyond the sort of spirited debate and disagreement upon which the American experiment was founded. It represents a gray area in the connection between violent language and violent acts, an area that Kurt Braddock has spent years studying. Learn about research on the connection between real bloodshed and coded language, dogwhistles, and implicit calls for violence with Dr. Braddock, who has conducted research on communication and terrorism for several national and international organizations, including the U.S. Department of Homeland Security, the U.S. Department of State, and the United Nations Office of Counter Terrorism. Professor Braddock will give his audience a firm grounding in the concept of “stochastic terrorism,” or political violence spawned by vague calls to violent action. Tapping into decades of research on communication and decision-making and accounts of specific violent acts inspired by implicit orders, he’ll show us that the threat posed by implicit calls to violence is real. He’ll discuss whether implicit calls for violence represent a “new” form of political communication protected by the First Amendment, and he’ll describe the real-world dangers posed by these kinds of statements. Among the questions Dr. Braddock will tackle: Why do politicians use this language if they can reasonably assume that someone may be motivated by it to hurt someone else? Perhaps most importantly, what can we do about it, especially given the sacrosanctity of the First Amendment? His talk promises to give you a much more sophisticated understanding of recent events and a clearer sense of what might lie ahead. (Door: $17, or $15 with a student ID. Listed time is for doors.

Title: Geometric Machine Learning with Symmetries and Graphs: Applications in Molecular Problems Date: Jan 31 2026 Noon - 14:00 EST Abstract: For geometric problems, symmetry equivariant machine learning has emerged as the modus operandi. In physics, symmetry is treated as the north star, the guiding principle for problem characterization and method optimization. Geometric features are inherently compatible with continuous Lie groups (and therefore symmetries), leading to continuous parametrization and successful training methodologies. The general mapping of a classical embedding and a quantum mechanical embedding will be discussed in terms of group theoretical concepts. In the context of embeddings, graph embedding is also a powerful method for machine learning problems taking better care of inter-relations among nodal variables. Classical and quantum neural networks with different subsets of the concepts mentioned will be defined and learning attempted with. The dataset under study is geometric molecular data (from quantum mechanical models) with varying geometric complexity. Performance comparison will include accuracy metrics, generalizability metrics, and.general remarks about expressivity.

He has been serving as a PostDoc at University of Maryland from 2022. He is also active in the technology subspace, working with the companies Apsidal LLC and Sapienly for AI and quantum information innovations.

### Tools in your AI's Toolbox : An introduction to MCP Servers The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way? This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents. Join this session for a developer-focused introduction where you will learn how to: Understand the core concepts of the open-source Model Context Protocol and its architecture. Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases. Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI. Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem. Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.
