**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. Bio: Dr Saumya Biswas completed a Master's degree in electrical engineering from University of California Riverside in 2016, a PhD in Physics from University of Oregon in 2021. 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. Moderators: Dr. Sebastian Zajac, member of QPoland, Dr. Pawel Gora, CEO of Quantum AI Foundation

Learn to manage stress and achieve self-growth through simple relaxation and Meditation. Heartfulness Meditation is a simple, modern, methodical approach to meditation. Rather than homing in on your breath or repeating a mantra, you simply focus inward, on your heart, to cultivate inner strength and serenity. Heartfulness meditation is gaining traction in recent years. It focuses on the heart, allowing individuals to connect with themselves on a deeper level, and ultimately achieve peace, relaxation, and clarity. It is a practice that encourages patience, self-compassion, and acceptance, helping cultivate a deeper appreciation for the present moment. This practice is offered with love and at no cost

### 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.
