Venez apprécier l'ambiance chaleureuse d'une conversation en français autour d'un verre de vin et d'apéritifs à moitié prix. C'est ouvert à tous quelque soit votre niveau, que vous soyez débutant ou bien que le Français soit votre langue maternelle. It is irresistible, to enjoy French convo with half-priced appetizers, glass of wine and rail drinks. The Event is open to all levels of French language, from beginners to native fluency. ***GRAB A DRINK AND YOU ARE 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. 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/)).

**AI-Supported Creative Exploration** *For Unassuming Intuitives & Practicing Creatives* (Please note that this event has not been organized or endorsed by The Writer's Center.) This meetup is part of AI as Creative Partner — A Practice Group, a set of open, non-sequential creative labs you can join at any point. We use AI as a thinking partner—not to replace your ideas, but to help surface and shape them without overthinking or pressure. You bring fragments—ideas, impulses, unfinished concepts. With AI as a supportive collaborator, we explore how those fragments can become clearer, more coherent, and ready to share if and when you want to. No technical background is required. If you can talk or type, that's enough to work with AI here. This session is intentionally low-commitment and flexible: * Arrive late or leave early * Work quietly or observe * Ask questions, or simply watch the process unfold There's no presentation and no expectation to finish anything. Showing up as you are is enough. **FROM FRAGMENT TO FORM - AN OPEN AI STUDIO** Many creative ideas don't arrive as "projects." They arrive as fragments, moods, or something that won't leave you alone. This open studio is a place to gently explore those fragments using AI as a thinking partner—without forcing clarity too soon. You're welcome to work, observe, arrive late, or leave early. This is a calm room for unfinished ideas. **HOW TO FIND US** Look for the room with the door open on the lower level. Look for the guy with the screen projector and ambient light and sound. Feel free to just walk in and settle. **(*This is an independent meetup using rental space at The Writer's Center. The Writer's Center has not organized or endorsed this event.*)**

Details Location: Crimson Whiskey Bar (Downstairs Bar, Not Rooftop) The purpose of Thinkers and Drinkers is to facilitate casual but meaningful and interesting conversations with other people in a face-to-face setting. The topics cover a wide variety of issues and are different for every meeting. While conversations may get heated at times, we ask that all members be respectful of each other and refrain from personal insults. Topic: Trust in Institutions Across much of the world, trust in major institutions, including government, media, corporations, courts, universities, and science, appears to be shifting. Surveys often show declining confidence in public institutions, while at the same time people continue to rely on them for stability, information, and coordination. Recent years have included disputed elections, misinformation concerns, public health crises, economic disruptions, and rapid technological change. These events have raised difficult questions about credibility, legitimacy, and accountability. Some argue that skepticism toward institutions is healthy in a democracy, encouraging transparency and reform. Others worry that widespread distrust can weaken social cohesion and make collective problem solving nearly impossible. Major surveys and studies on institutional trust include: • Pew Research Center, Public Trust in Government: https://www.pewresearch.org/politics/2024/04/30/public-trust-in-government-1958-2024/ • Edelman Trust Barometer (annual global survey): https://www.edelman.com/trust/trust-barometer • Gallup, Confidence in Institutions: https://news.gallup.com/poll/1597/confidence-institutions.aspx • World Values Survey, Trust indicators across countries: https://www.worldvaluessurvey.org Historically, periods of low institutional trust have sometimes preceded major reforms or political realignments, while in other cases they have contributed to instability or authoritarian backlash. Understanding when distrust is justified, and when it becomes dangerous, remains an open question. Questions to Consider • What factors most strongly shape trust in institutions, performance, transparency, shared identity, or something else? • Is declining trust primarily a problem, or can it be a healthy corrective? • Are some institutions, such as courts, science, or local government, more deserving of baseline trust than others? • How should societies respond when large portions of the public lose faith in elections, media, or public health guidance? • Can trust be rebuilt once it is lost, and if so, how? • Does technology, especially social media and AI, strengthen or weaken institutional legitimacy?

Paraphrased from BGG: ***Rurik: Dawn of Kiev*** is a euro-style realm building game set in an 11th century Eastern European Kingdom. It features area control, resource management, and a unique mechanic, "auction programming." You play as a potential successor to the throne following the death of your father, Vladimir the Great, in 1015. You must establish your legacy by building, taxing, fighting, and accomplishing great deeds. Will you win over the hearts of the people to become the next ruler of Kyivan Rus? The "auction programming" mechanism in *Rurik* allows players to openly bid for actions with their advisors. Stronger advisors earn greater benefits at the cost of performing their actions later than other players. Conversely, weaker advisors earn fewer benefits but perform their actions earlier. We have three copies of the game. So we will limit RSVPs to 12. After we have 12, new sign-ups will go on the waiting list. If you’re able to bring a copy, let us know, and we will increase the RSVP limit.

Title: An Easy Intro to Feynman's Quantum ElectroDynamics (QED) Summary: One of the most delightful and informative physics books ever written is Richard Feynman’s QED. In this short book, Feynman undertook the daunting task of explaining his Nobel-Prize-winning theory, Quantum ElectroDynamics, without any math except in a few elaborating footnotes. Remarkably, he succeeds! In this talk, Terry replicates many of his arguments to show how you, too, can understand one of the most fundamental mechanisms of physical reality by using not much more than lots of tiny one-hand clock dials moving through space. Speaker: Terry Bollinger is a computer scientist Speaker: Terry Bollinger is a computer scientist with BS, MS and Professional degrees from the Missouri University of Science and Technology.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!
