[Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Doom and Dinosaurs,”** a look at how mass extinctions shaped the dinosaurs and what research on these events tells us about Earth life’s long-term prospects, with Ian Wilenzik, paleontologist and visiting assistant professor of biology at George Washington University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-doom-and-dinosaurs](https://events.ticketleap.com/tickets/profsandpints/dc-doom-and-dinosaurs) .] Pity the poor dinosaurs. They lacked both scientific research to help deal with potential environmental catastrophes and places where they could have a beer and discuss it. You, on the other hand, have the opportunity to come to Profs and Pints to hear a fascinating talk on the impact of mass extinctions on dinosaur evolution and what research on dinosaurs tells us about biodiversity and Earth’s current biodiversity crisis. Dr. Ian Wilenzik, who has studied and taught courses on dinosaur evolution, population spread, and extinction, will leave you with a greater appreciation of the resilience of life on earth and how we’re both the product and source of biologically catastrophic events. Many of us are familiar with how a big meteor impact about 66 million years ago wiped out the Earth’s dinosaur population, leaving us only with their feathered descendants, birds. Less well known is how the Earth actually has undergone five periods of mass extinction that wiped out nearly all life, and how dinosaurs arose from one and endured another—both caused by volcanic activity—before meeting their match in the third. To ground his discussion, Dr. Wilenzik will talk about how we study mass extinctions by looking for geologic evidence of volcanic activity, meteoric blasts, and other catastrophic activity and of gaps in the fossil record after them. He’ll also discuss what makes a dinosaur a dinosaur, describing their distinct anatomical features. He’ll talk about how they and other forms of life evolved over long periods of time and were affected by extinction events. We’ll look at how the meteor-caused mass extinction that wiped out dinosaurs at the end of the Cretaceous paved the way for the rise of mammals and the emergence of primates, and, eventually, us. Looking ahead to future mass extinctions and what might survive them, we’ll talk about how that plant you forget to water might have the last laugh, as well as why crocodiles might be around a while. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.)

**Tired of surface-level conversations?** Join us for *Ditch the Small Talk*—an evening of deep, real connection with strangers who are down to go there. We’ll meet in the grass in front of the cathedral, break into small groups, and draw questions from a deck of cards designed to spark vulnerable, honest conversations. How it works: Draw a card and ask a question. Listen. Don't coach or give advice without permission. Try to ask follow-up questions when people share. You can spend 1 minute on a question or 1 hour, just go with the flow. **If you show up late, please don't interrupt the speaker. Just sit down in a group of your choice and they'll bring you up to speed when whoever is talking finishes. Bring a blanket or chair if you don't want to sit in the grass. *** Rules*** 1. Don't debate politics 2. Keep what is shared in the group within the group 3. If you need to use your phone, step away from your group first

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Facing Fascism,”** on the history, hallmarks, and lingering power of a deadly ideology, with Kevin Matthews, professor of history at George Mason University and teacher of courses on early 20th century European history. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-facing-fascism](https://events.ticketleap.com/tickets/profsandpints/nv-facing-fascism) .] Few political movements have aroused as much anger and fear as fascism. But despite its legacy of violence, persecution, and genocide, fascism continues to hold a strange attraction to many. Join historian Kevin Matthews for an in-depth look at an ideology that brought death to millions in Europe and yet continues to deeply influence our politics and culture. Dr. Matthews will start by discussing how the ideology of fascism arose in the aftermath of the First World War and took hold in Europe in the 1920s and 1930s. To give you a better grasp of what exactly fascism is, he’ll discuss its central themes: Anti-democracy. Extreme nationalism and anti-communism. The use, or threat, of violence in politics. Rejection of established values such as scientific objectivity. Denial of equal rights, especially for women. The assertion of power where a power vacuum exists. We’ll examine the rise and fall of two notorious fascist dictators, Adolf Hitler of Germany and Benito Mussolini of Italy. For a time it was believed that fascism died in the ashes of the Second World War, but it clearly didn’t, and we’ll look at where it remains a political force today. Finally, we’ll examine how fascism continues to permeate popular culture in ways that trivialize it, popping up in music from punk to Madonna, with its latent eroticism making it the subject of films such as *The Night Porter.* Having been called “the most self-consciously visual of all political forms,” it enlisted fashion leaders to produce uniforms and continues today to inspire a look known as “Nazi chic.” Dr. Matthews previously has given fantastic Profs and Pints talks on Ireland’s fight for independence and on World War II German submarine attacks off our coasts. He’s sure to leave you with a much better understanding of fascism and a recognition that is has hardly gone away. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.) Image: Benito Mussolini and Adolf Hitler during Mussolini's 1940 visit in Munich (photographer unknown / public domain).

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

A WiA Collective Wisdom Exchange At the start of this year, we gathered to look back, set intentions, and imagine the next chapter. This is the follow-up. Not a check-in. Not a progress report. A small, facilitated circle to reconnect with what you said mattered — and honestly explore what’s actually happening now. Together, we’ll explore: • What you intended at the start of this year - and what that looks like three months in • What’s surprised you, supported you, or shifted • What the next chapter needs now that you know what you know If you were at our January gathering, bring whatever you made or wrote — your word, your artifact, your intention. We’ll look at it with fresh eyes. If this is your first time, you belong here too. You’ll start where we all started: with what’s true right now. Optional art materials will be available for anyone who wants to reflect creatively alongside conversation. If you brought something home from January, you’re warmly invited to bring it back. The intention is the same as always: everyone leaves feeling more clear, more connected, and a little lighter. Space is intentionally limited to keep the experience intimate. What to Expect • A small, welcoming circle (not a large meetup) • Structured conversation so everyone has space to speak • Reflection, listening, and lived experience — not advice-giving • Optional creative reflection alongside conversation • A calm, supportive environment Who This Is For Women and underrepresented folks working in or around agile, product, technology, leadership, or organizational change — especially those looking for honest conversation and community beyond frameworks and buzzwords. Good to Know • No preparation required • If you attended in January, we invite you to bring anything you created or wrote (or something that represents your intention at the start of the year) - it’s optional but invited • Participation is invitational; listening is always welcome • Creative activities are optional
